If the third and fourth term of an arithmetic sequence are -1 and -4, what are the first and second terms?

Answers

Answer 1

Answer: 5 and 2

Step-by-step explanation:

In an arithmetic sequence, the difference between consecutive terms is constant. Since the third and fourth terms are -1 and -4, the common difference is -4 - (-1) = -3. Therefore, the second term is -1 - (-3) = 2 and the first term is 2 - (-3) = 5. So the first and second terms of the sequence are 5 and 2 respectively.

Define compound interest?

One way to earn or pay interest on interest is through compound interest. It denotes that interest will be charged on both the main amount and the accrued interest in the subsequent period. Savings or investments can expand over time with the aid of compound interest.

We can use the following formula to determine compound future value:

FV = P * (r/n + 1)(n*t)

where P is the principal, r is the yearly interest rate, n is the number of times interest is compounded annually, and t is the amount of time in years.

Your values have led us to:

FV = 15300 * (1 + 0.08/4)²⁴

FV = $24,947.06

The total is $24,947.06 plus $9,647.06 in interest.

A house is purchased for $313,000 with a 15% down payment. A mortgage is secured at 7% for 25 years. Find the monthly payment.

Answers

If house is purchased for $313,000 with a 15% down payment, the monthly payment for the mortgage is $1,906.33.

To find the monthly payment for a mortgage secured at 7% for 25 years on a house purchased for $313,000 with a 15% down payment, we can use the formula for calculating mortgage payments:

P = L[c(1 + c)ⁿ]/[(1 + c)ⁿ - 1]

Where P is the monthly payment,

L is the loan amount (which is the purchase price minus the down payment),

c is the monthly interest rate (which is the annual interest rate divided by 12),  

n is the total number of monthly payments (which is the number of years multiplied by 12).

Substituting the given values, we get:

L = $313,000 - 0.15($313,000) = $266,050

c = 0.07/12 = 0.00583

n = 25 x 12 = 300

Plugging these values into the formula, we get:

P = $266,050[0.00583(1 + 0.00583)³⁰⁰]/[(1 + 0.00583)³⁰⁰ - 1]

Simplifying the expression, we get:

P = $1,906.33

The mixed fraction 1 and 1/4 is equal to 5/4 and the mixed fraction 1 and 1/2 is equal to 3/2.

Given first number = 1 and 1/4.

1 and 1/4 is a mixed fraction so, we can write it in the form as  [tex]1\frac{1}{4}[/tex] .

To find the value of  [tex]1\frac{1}{4}[/tex]  we have to multiply 4 with 1 and add the numerator part of the fraction which is 1 and then divide it by 4 which is the denominator. So,

 [tex]1\frac{1}{4}[/tex]  = ((4x1) + 1 )/4 = 5/4.

Similary, for 1 and 1/2,

[tex]1\frac{1}{2}[/tex] = ((2x1) + 1)/2 = 3/2.

What is the perimeter of the regular pentagon?

Answers

Answer:

To find the perimeter of a regular pentagon, you need to know the length of one side and the number of sides. In a regular pentagon, all sides have the same length and the shape has 5 sides.

Let's say the length of one side of the regular pentagon is 's'.

The formula for the perimeter of a regular pentagon is:

Perimeter = 5s

This is because a regular pentagon has 5 sides of equal length, so you can simply add the length of each side together 5 times.

Therefore, the perimeter of a regular pentagon with a side length 's' is 5s.

A motorist travelled from Town A to Town B. After travelling for 1 1/2 hours , he passed
a cyclist travelling at an average speed of 45 Km/h in the opposite direction.
when the motorist reached Town B 2 h later, the cyclist was 30 km away from Town A.

a) Find the average speed of the motorist.

b) Find the distance between Town A and Town B.

Answers

Answer:

the formula: Speed = Distance / Time.

Let's break down the problem into two parts:

a) Find the average speed of the motorist.

Let's assume the average speed of the motorist is "v" km/h.

The distance the motorist traveled in 1 1/2 hours is given by: Distance = Speed × Time = v × (3/2) km.

The distance the cyclist traveled in 1 1/2 hours (opposite direction) is given by: Distance = Speed × Time = 45 × (3/2) km.

Since they passed each other, the sum of their distances should be equal to the distance between Town A and Town B.

So, we can set up the equation: v × (3/2) + 45 × (3/2) = Distance between Town A and Town B.

b) Find the distance between Town A and Town B.

When the motorist reached Town B 2 hours later, the cyclist was 30 km away from Town A.

We can set up the equation: Distance between Town A and Town B = v × 2 + 30.

Now, let's solve the equations:

v × (3/2) + 45 × (3/2) = v × 2 + 30.

Simplifying the equation, we have: (3v + 135)/2 = 2v + 30.

Multiplying both sides of the equation by 2 to eliminate the fraction, we get: 3v + 135 = 4v + 60.

Subtracting 3v from both sides of the equation, we have: v = 75.

Therefore, the average speed of the motorist is 75 km/h.

To find the distance between Town A and Town B, we substitute the value of v into the equation:

Distance between Town A and Town B = v × 2 + 30 = 75 × 2 + 30 = 150 + 30 = 180 km.

Therefore, the distance between Town A and Town B is 180 km.

Find the are of the shaded shape below it has two lines of symmetry (vertical and horizontal) that pass through its centre
Give your answer in cm^2

Answers

The area of the shaded shape is 62.5cm^2.

To find the area of the shaded shape, we need to break it down into simpler shapes that we can calculate the area of. From the image, we can see that the shape is composed of a rectangle and two right-angled triangles.

First, we need to find the dimensions of the rectangle. Since the shape has vertical and horizontal lines of symmetry passing through its center, we know that the rectangle is divided into four equal parts.

Therefore, the length of the rectangle is twice the length of one of the triangles, which is 5cm. So, the length of the rectangle is 2 x 5cm = 10cm. The width of the rectangle is also 5cm.

Next, we need to find the area of each of the triangles. We know that the base of each triangle is 5cm, and the height is half of the width of the rectangle, which is 2.5cm. Therefore, the area of each triangle is:

0.5 x base x height = 0.5 x 5cm x 2.5cm = 6.25cm^2

So, the total area of the two triangles is 2 x 6.25cm^2 = 12.5cm^2.

Finally, we can find the area of the shaded shape by adding the area of the rectangle and the area of the triangles:

Area = rectangle area + triangle area = 10cm x 5cm + 12.5cm^2 = 62.5cm^2.

Complete the following statement to estimate the root of 75 to the nearest tenth. Use numbers that are closest to the root of 75

Answers

Answer:

√75 =8.66.

Step-by-step explanation:

The square root of 75 is an irrational number where the numbers after the decimal point go up to infinity. √75 = 8.660.√75 cannot be written in the form of p/q, hence it is an irrational number. irrational with never-ending digits.

How to Find the Square Root of 75?

Let's see how to find the square root of 75 by the long division method.

Step 1: Express 75 as 75.000000. We take the number in pairs from the right. Take 75 as the dividend.

Step 2: Now find a quotient which is the same as the divisor. Multiply quotient and the divisor and subtract the result from 75.

Step 3: Now double the quotient obtained in step 2. Here is 2 × 8 = 16. 160 becomes the new divisor.

Step 4: Apply decimal after quotient '8' and bring down two zeros. We have 1100 as the dividend now.

Step 5: We need to choose a number that while adding to 160 and multiplying the sum with the same number we get a number less than 1100. 160+ 6 = 166 and 166 × 6 = 996. Subtract 996 from 1100. We get 104

Step 6: Bring down two zeros again and place it after 104, so that it becomes 10400 which is the new dividend. Now multiply the number in the quotient by 2. Here it is 86. We get 172. Have it as 1720. Now find a number at the unit's place of 1720 multiplied by itself gives 10400 or less. We find that  1726  × 6 = = 10356. Find the remainder.

Step 7 : Repeat the process until we get the remainder equal to zero. The square root of 75 up to two places is obtained by the long division method. Thus √75 = 8.66

A company gives a 12% discount to his customers on retail price. If the total is over $10,000 after the discount, they give an additional 3% discount on the remaining balance. A customer’s total came to $13,500 (discounted price). How much did he save?

Answers

Answer:

Therefore, the customer saved $2,448.45.

Step-by-step explanation:

To answer this question, we need to use the percentage discount formula to find the original price and the amount saved.

Let x be the original price of the product. Then, after applying the 12% discount, the price becomes 0.88x. If the total is over $10,000 after this discount, then an additional 3% discount is applied on the remaining balance, which means the final price becomes 0.97 * 0.88x.

We are given that the final price is $13,500, so we can set up an equation and solve for x:

0.97 * 0.88x = 13,500 x = 13,500 / (0.97 * 0.88) x = 15,948.45

Therefore, the original price was $15,948.45.

The amount saved is the difference between the original price and the final price:

15,948.45 - 13,500 = 2,448.45

In the diagram shown, points B and D lie on sides AC and AE such that BD is parallel to CE. If AB=10, AD=16, and De=22 then find the length of AC

Answers

In triangle ACE, with BD parallel to CE, using similar triangles and ratios, we get a quadratic equation with two possible solutions. Only the positive one is chosen, so AC is approximately 30.96 units long.

Since BD is parallel to CE, we can use the property of similar triangles to find the length of AC.

Triangles ABD and ACE are similar because they have the same corresponding angles. This means that the ratios of their corresponding side lengths are equal.

We know that AB = 10, AD = 16, and DE = 22.

Let x be the length of AC. Then, we have

AB/AD = CE/EA (by similarity of triangles ABD and ACE)

10/16 = CE/(x-16+22) (substituting CE = EA - DE and simplifying)

5/8 = CE/(x-6)

CE = (5/8)(x-6)

We also know that

BD/DE = AB/AE (by similarity of triangles ABD and ADE)

BD/22 = 10/(x-22) (substituting BD = CE and AE = AC - CE - DE, and simplifying)

CE = (220 - 10x)/(x-22)

Since CE is equal in both expressions, we can equate them and solve for x

(5/8)(x-6) = (220 - 10x)/(x-22)

5x² - 196x + 1320 = 0

x² - 39.2x + 264 = 0

Using the quadratic formula, we get

x = 30.96 or x = 8.54

The length of AC must be positive, so we choose x = 30.96.

Therefore, the length of AC is approximately 30.96 units.

How to calculate the length of the arc?

In Mathematics and Geometry, if you want to calculate the length of an arc formed by a circle, you will divide the central angle that is subtended by the arc by 360 degrees and then multiply this fraction by the circumference of the circle.

Mathematically, the length of an arc formed by a circle can be calculated by using the following equation (formula):

The distance from Hans house to Priyas house is 4/5 kilometer. Han has walked 3/4 of the way already. How many kilometers has he walked?

Answers

Han has walked 3/5 km.

What is distance?

Distance is the length of space between two reference points. It is a scalar quantity, and it is measured in meters.

In the given question, we have that;

distance from Han's house to Priya's house = 4/5 km

Han has walked 3/4 of the way already.

Thus,

distance walked by Han = 3/4 of 4/5

                                         = 3/4 x 4/5

                                         = 12/ 20

                                         = 3/ 5

distance walked by Han is 3/5 km.

The sound wave of two music notes can be represented by the function y = 2sin2x and y = sin x, where x represents the time since the note is played. At what times will the frequencies of the sound waves be the same in the interval [0°, 360°)?
Group of answer choices

x = 0°, 30°, 150°, 180°

x = 0°, 180°, 210°, 330°

x = 30°, 90°, 150°, 270°

x = 90°, 210°, 270°, 330°

Answers

The correct answer is:

x = 0°, 30°, 150°, 180°

This is because the sine function equals 0 at 0° and 180° and equals 1/2 at 30° and 150°.

How to solve

For the frequencies to be the same, we need to find values of n and m such that:

n = m

Solving for n and m, we get:

n = m = 2

So both functions complete two cycles in the interval [0, 2π).

We can find the times when this occurs by setting the angles in radians equal to multiples of 2π/2, or π:

2sin2x = sin x

2sin2x - sin x = 0

sin x (2sin x - 1) = 0

sin x = 0 or 2sin x - 1 = 0

sin x = 0 when x is an integer multiple of π.

2sin x - 1 = 0 when sin x = 1/2, which occurs when x = π/6 or x = 5π/6.

Therefore, the frequencies of the sound waves are the same at x = π/6, x = π/2, x = 5π/6, and x = 3π/2.

The correct answer is:

x = 0°, 30°, 150°, 180°

This is because the sine function equals 0 at 0° and 180° and equals 1/2 at 30° and 150°.

Frank spends $90 on his $1800 monthly income what percent of monthly check does not go toward food

Answers

5% is spent on food
To find the answer we hav ego do these steps:
1800/100 = 18 - 18 dollars is 1%
90/18 = 5 - 90/18 = 5%
5% of his income is spent on food

If Frank spends $90 on his $1800 monthly income, then 95 percent of monthly check does not go toward food.

Let's say Frank spends $90 on food and has a monthly income of $1800. We can calculate the percentage of his monthly check that does not go towards food as follows:

Percentage = (Total Income - Food Expenses) / Total Income

Percentage = (1800 - 90) / 1800

Percentage = 0.95 = 95%

Therefore, 95% of Frank's monthly check does not go towards food.

Here are the steps in detail:

Subtract the food expenses from the total income to get the amount of money that is not spent on food.

Divide the amount of money that is not spent on food by the total income to get the percentage.

In this case, the amount of money that is not spent on food is $1800 - $90 = $1710. The percentage of the monthly check that is not spent on food is $1710 / $1800 = 0.95 = 95%.

When doubling the dimensions of a rectangle, why does the area quadruple and the perimeter only doubles?

Answers

If you double the length and the width, you are quadrupling the area.

This is because 2 × 2 = 4.

Perimeter of new rectangle=   2 × perimeter of initial rectangle.

The perimeter will be double of if we double the length and breadth of rectangle

→ When doubling the dimensions of a rectangle, why the area is quadruple:

We know that :

Area of rectangle = l × b

where, l is length and b is breadth

A = L × W

This means area equals length times width.

if you double the length and you double the width, the formula becomes:

A = 2 × L × 2 × W

A = 2 × 2 × L × W

A = 4 × L × W

if you double the length and the width, you are quadrupling the area.

This is because 2 × 2 = 4.

→When doubling the dimensions of a rectangle, why the perimeter is doubles?

Let length be equal to ′l′

And breadth be equal to ′b′

Perimeter of rectangle = 2 (l + b) ____(equation i )

The perimeter if the length and breadth of the rectangle will increase by two, or will it double? So new parameters of rectangle when its length and breadth will get double on initial one.

Double length of rectangle of initial one= 2 × l=2l

Double breadth of rectangle of initial one = 2×b=2b

So the perimeter of new rectangle whose length and breadth are double of initial one are:

As we know that:

Perimeter of rectangle = 2 (l + b)

So,

Perimeter of new rectangle= 2(2l+2b),  (by taking 2 common)

Perimeter of new rectangle = 2×2(l + b) ____  equation (ii)

As from equation (i) perimeter of initial rectangle is = 2(l + b)

So from equation (i) and (ii)

Perimeter of new rectangle= 2 × 2(l + b)

Perimeter of new rectangle=   2 × perimeter of initial rectangle.

Hence, the perimeter will be double of if we double the length and breadth of rectangle.
