Answers
Answer:
(x, y) -> (2.5x, 2.5y)
Step-by-step explanation:
To find which equation is correct, first, let's find a similar point of Figure J and Figure K.
Figure J: (-3, -2). Figure K: (-7.5, -5)As you can see, Figure J was enlarged by a SF of 2.5 because -3 x 2.5 = -7.5, and -2 x 2.5 = -5.
Therefore, the answer is (x, y) -> (2.5x, 2.5y).

What is the solution to the equation?
5(8 + 7) = 5•x + 5•7
Answers
Answer:
x = 8
Step-by-step explanation:
5( 8 + 7 ) = 5 ⋅ x + 5 ⋅ 7
Add 8 and 7 to get 15.
5 × 15 = 5x + 5 × 7
Multiply 5 and 15 to get 75.
75 = 5x + 5 × 7
Multiply 5 and 7 to get 35.
75 = 5x + 35
Swap sides so that all variable terms are on the left-hand side.
5x + 35 = 75
Subtract 35 from both sides.
5x = 75 − 35
Subtract 35 from 75 to get 40.
5x = 40
Divide both sides by 5.
x = [tex]\frac{40}{5}[/tex]
Divide 40 by 5 to get 8.
x = 8

The terminal ray of ∠A passes through the point (−4,−6). ∠A is drawn in standard position. What is the value of cscA?
Answers
The terminal ray of an angle A passes through the origin
The value of csc(A) is -1.2
How to determine the cosine of angle AThe coordinates of the terminal ray is given as:
(x,y) = (-4,-6)
Start by calculating the length (L) of the hypotenuse
[tex]L = \sqrt{x^2 + y^2}[/tex]
So, we have:
[tex]L = \sqrt{(-4)^2 + (-6)^2}[/tex]
Evaluate the exponent
[tex]L = \sqrt{52}[/tex]
Evaluate the root
[tex]L = 7.2[/tex]
The sine of the angle A is then calculated as:
[tex]\sin(A) = \frac{-6}{7.2}[/tex]
The csc of the angle A is then calculated as:
[tex]\csc(A) = \frac{1}{\sin(A)}[/tex]
So, we have:
[tex]\csc(A) = \frac{7.2}{-6}[/tex]
[tex]\csc(A) = -1.2[/tex]
Hence, the value of csc(A) is -1.2

The initial investment is compounded annually 3.25%
That means the equation will look like this:
[tex]500(1 + 0.0325) = 500 + 500 * 0.0325[/tex]
500(1 + 0.0325) is the initial investment plus the initial investment times the percentage which in the end will give you the total amount after the investment is compoundedHowever, we want it compounded yearly for every year after the first initial investment
---> [tex]500(1+0.0325)^t[/tex]
Therefore the equation is the amount of money in the account after 't' year or the second choice.
