Rachel had a loan for $4,000 loan for 4 years.
She paid a total of $608 in simple interest over the 4 years.
What was the annual interest rate for the loan?

Answer:

7.8

Step-by-step explanation:

We can use pythagorean theorem [tex](a^2+b^2=c^2)[/tex] where a and b are sides of a right triangle and c is the hypotenuse.

[tex]x^2+13.3^2=15.4^2[/tex].

[tex]x^2=15.4^2-13.3^2\\[/tex]

[tex]x^2=237.16-176.89\\x^2=60.27\\x=7.763[/tex]

Rounded to the nearest tenth, x = 7.8

Answer:

1. [tex]\frac{3}{8}[/tex]

2. [tex]\frac{1}{4}[/tex]

3a. [tex]-\frac{1}{4}[/tex]

3b. 3

3c. [tex]-\frac{4}{5}[/tex]

4. [tex]m = \frac{y_1 - y_2}{x_1-x_2}\\[/tex]

Step-by-step explanation:

1.

Rises 6 inches for every horizontal change of 16 inches

Slope = rise/run

Slope = 6/16

Slope = 3/8

2.

Rises 3 feet for every horizontal change of 12 feet

Slope = rise/run

Slope = 3/12

Slope = 1/4

3a.

[tex]m = \frac{y_1 - y_2}{x_1-x_2}[/tex]

[tex]m = \frac{3-2}{-2-2}[/tex]

[tex]m = \frac{1}{-4}[/tex]

[tex]m = -\frac{1}{4}[/tex]

3b.

[tex]m = \frac{y_1 - y_2}{x_1-x_2}\\[/tex]

[tex]m = \frac{-1 - 2}{-1-0}[/tex]

[tex]m = \frac{-3}{-1}[/tex]

[tex]m = 3[/tex]

3c.

[tex]m = \frac{y_1 - y_2}{x_1-x_2}\\[/tex]

[tex]m = \frac{1 - (-3)}{-1-4}\\[/tex]

[tex]m = \frac{4}{-5}\\[/tex]

[tex]m = -\frac{4}{5}[/tex]

4.

[tex]m = \frac{y_1 - y_2}{x_1-x_2}\\[/tex]

Compound interest is the interest generated on a sum of money invested. The amount of money that you will have in your account after 25 years is  $122,653

Compound interest is the interest generated on a sum of money invested. The formula for calculating compound interest is expressed as:
A = P(1+r/n)^nt

Given the following parameters

Principal P = $3600 (a year)
rate r = 0.03
Time  t = 25 years

n  = 12 (time of compounding)

Substitute

A = 3600(1 + 0.03/12)^12(25)
A = 3600 (1.0025)^300
A = 3600(2.1150)
A = $122,653

Hence the amount of money that you will have in your account after 25 years is  $122,653

So substitute into the formula:

4x - 1 + 6x - 3 /2 × (x - 5)

1. 4x - 1 + 6x - 3 (collect all like terms)

4x + 6x + -1 -3 = 10x - 4

2. 10x - 4 / 2

The standard form of the equation y=(x-1)²-9 is y=x²-2x-8

Two or more expressions with an Equal sign is called as Equation.

y=(x-1)²-9 equation is in the form of a quadratic equation

where y is the unknown variable and x is the known variable.

The equation can be written in standard form by expanding the (x-1)² term and combining like terms.

y=(x-1)²-9

y=x²+1-2x-9

Combine the like terms

y=x²-2x-8

The expanded form of the equation is y=x²-2x-8

Hence, the standard form of the equation y=(x-1)²-9 is y=x²-2x-8

Answer:

addition or multiplication

Answer:

B

Step-by-step explanation:

Firstly, we will take a look at the equation and the options listed to choose from.

Secondly, we notice these options are reffering to rational and irrational numbers.

A rational number is a number that can be expressed in a ratio of 2 integers. (Form example whole numbers such as 1 (1/1), 2(2/1) 5(5/1, 10/2) and even decimals like 3.75 (375/100) or (750/200) etc.

As for irrational numbers, these can NOT be simplified between a ratio 2 integers. For example the question states 3 multiplied by the square root of 5. The square root of 5 is 2.2360679... multiplied by 3 we get 6.7082..... Numbers such as those can go on for infinity and can not be simplified as integers therefore they are irrational numbers.

With this knowledge, it means then options A and C are out. So lets take a look at B and D which statement is true and which is false?

With this knowledge, it means then options A and C are out. So lets take a look at B and D which statement is true and which is false?B is true because we already know that the product of the numbers was 6.708.... irrational number based on our workings above.

So lets take a look at B and D which statement is true and which is false?B is true because we already know that the product of the numbers was 6.708.... irrational number based on our workings above.D is false because if the product is 6.708 it can not be the square root of 15 (3.872)

B. It is an irrational number because the product of the side lengths is [tex]3\sqrt{5}[/tex], an irrational number.

According to this question, we know the lengths of the two sides of the rectangle, the length of a side is an positive integer and the length of the other one is an positive irrational number. The area of the rectangle is the product of the two sides lengths mentioned above.

By algebra, we know that the product between an integer and an irrational number leads to other irrational number. Therefore, the area of the rectangle is represented by an irrational number.

[tex]A = (3)\cdot \sqrt{5}[/tex]

[tex]A = 3\sqrt{5}[/tex]

Hence, the right answer is B.
