Answer:

15) 30°

16) 49.5°

Step-by-step explanation:

15) We solve using the Trigonometric function of Sine

sin θ = Opposite/Hypotenuse

Opposite = 12

Hypotenuse = 24

sinθ = 12/24

θ = arc sin(12/24)

= 30°

Approximately = 30°

16)We solve using the Trigonometric function of Cosine

cos θ = Adjacent/Hypotenuse

Adjacent = 13

Hypotenuse = 20

cos θ = 13/20

θ = arc cos (13/20)

= 49.458398126°

Approximately = 49.5°

Function A) Rate of change is 6 because it represents 'm' from mx (6x).

Function B) Rate of change is 5 because there is an increase of 5 as it moves to the right.

Answer:

a) (-25)(4)

Step-by-step explanation:

To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations. In this case,

withdrew means no longer there which means subtracted.

Then, times mean multiply.

Therefore, -minus twenty-five times (x) four

combine them and it equals (-25)(4)

Answer:

4.5 mph

Step-by-step explanation:

2 m/s = (2 m/s)(60)(60) = 7200 m/h or 7.2 km/hr

if 5 miles = 8 km, then 1 km = 0.625 miles

7.2 x 0.625 = 4.5 mph

The quotient is the outcome of the division one number or expression known as the dividend, by another number or expression known as the divisor

The option that gives the correct quotient is;

[tex]\mathbf{2\cdot x + 1 + \dfrac{2 \cdot x - 5}{x^2 + x + 1}}[/tex]

Where, the quotient is 2·x + 1, and the reminder is 2·x - 5

The reason the above option is correct is as follows:

The given dividend is 2·x³ + 3·x² + 5·x - 4

The divisor is x² + x + 1

By long division of a polynomial we have;

2·x + 1(Quotient)

(2·x³ + 3·x² + 5·x - 4) ÷ (x² + x + 1 )

2·x³ + 2·x² + 2·x

0    +   x²  + 3·x - 4

[tex]{}[/tex]           x² + x    + 1

[tex]{}[/tex]           0  + 2·x - 5

Therefore, we have;

[tex]\dfrac{2\cdot x^3 + 3 \cdot x^2 + 5 \cdot x - 4}{x^2 + x + 1} = 2\cdot x + 1 + \dfrac{2 \cdot x - 5}{x^2 + x + 1}[/tex]

Therefore, the correct option is;

[tex]\mathbf{2\cdot x + 1 + \dfrac{2 \cdot x - 5}{x^2 + x + 1}}[/tex]

The table for total repayment and interest paid for each loan offer:

Loan offer Interest rate Total repayment Total interest paid

1-year loan 6.5%         $37,275                 $2,275

5-year loan 8.2%         $41,570                 $6,570

Simple interest is an amount which is calculated for a certain period of time and for a certain rate, in simple interest calculation there are three factors which we consider: principal amount(P), rate(R) and time(T).

Formula;    Simple Interest(I) =  P × R × T/100

For the 1-year loan, the total repayment and total interest paid can be calculated as follows:

Total repayment = Principal + Interest = $35,000 + (0.065 x $35,000)

                                                               = $37,275

Total interest paid = $37,275 - $35,000

                               = $2,275

For the 5-year loan, the total repayment and total interest paid can be calculated as follows:

Total repayment = Principal + Interest

                            = $35,000 + (0.082 x $35,000 x 5)                

                            = $41,570

Total interest paid = $41,570 - $35,000 = $6,570

Loan offer Interest rate Total repayment Total interest paid

1-year loan 6.5%         $37,275                 $2,275

5-year loan 8.2%         $41,570                 $6,570

Answer:

0 units

Step-by-step explanation:

What's the length of one leg of a right triangle if the length of the hypotenuse is 25 units and the length of the other leg is 25 units?

The formula to solve for the sides of a right angled triangle

= Hypotenuse² = Opposite² + Adjacent ²

Hypotenuse = 25 units

One side = 25 units

To find the other side

√ 25² - 25²

= √625 - 625

= √0

= 0 units

The length of the other leg = 0 units

Answer:

12 years

Step-by-step explanation:

Given that

P = 5,600 e^0.0591

Reaching amount = 11,200

time period = t

We need to find out the time period i.e. t

So,

11,200 =  5,600 e^0.0591t

2 =  e^0.0591t

Now take the log on both the sides

ln2 = 0.0591t ln

t = ln2 ÷ 0.059

= 0.693147÷ 0.059

= 11.748

$100 profit, $300 cost

Step-by-step explanation:

So 25% of $400 is $100, now we know she made $100 on the article

and the other $300 was the amount used to make the article i'm asuming

A woman sold an article for 400.00

made a profit of 25%

Cost price and profit​ is $100 profit, $300 cost.

There are four levels of profit or profit margins: gross profit, operating profit, pre-tax profit, and net profit.

These are reflected on a company's income statement in the following sequence: A company takes in sales revenue, then pays direct costs of the product of service.

Profit is a term that often describes the financial gain a business receives when revenue surpasses costs and expenses. For example, a child at a lemonade stand spends one quarter to create one cup of lemonade. She then sells the drink for $2. Her profit on the cup of lemonade amounts to $1.75.

1020 students

Step-by-step explanation:

Given the trend line equation :

y = 0.1x + 18,

where y is the total number of staff members and x is the total number of students.

Using the equation, the predicted number of students in a school with 120 staffs ;

y = 120

y = 0.1x + 18

120 = 0.1x + 18

120 - 18 = 0.1x

102 = 0.1x

x = 102 / 0.1

= 1020 students
