The correct answer is C. ordered pair negative 3 divided by 2 comma 3 square root 3 divided by 2

(r,θ) = (x,y)
x = r * cosθ
y = r * sinθ
Since your θ is 5π3, set your calculator to radians before taking the sine and cosine.

(3 cos 5π / 3, 3 sin 5π / 3)
(3* 1 / 2, 3 * - sqrt(3) / 2)
(3 / 2, −3 sqrt (3) / 2)
if r = -3, then x is negative, y is positive.

Here are the following choices:
A. ordered pair negative 3 divided by 2 comma 3 divided by 2
B. ordered pair 3 square root 3 divided by 2 comma negative 3 divided by 2
C. ordered pair negative 3 divided by 2 comma 3 square root 3 divided by 2
D. ordered pair 3 divided by 2 comma negative 3 divided by 2

Answer:

1) f(x) = x/8 - 7

2) f(x) = 1 - x/3

3) f(x) = 20 - 0.25x

4) f(x) = x + 7

Step-by-step explanation:

f^-1 = 8(x + 7)

x + 7 = y/8

x = y/8 - 7

f(x) = x/8 - 7

f^-1 = -3(x - 1)

y/-3 = x - 1

x = 1 - y/3

f(x) = 1 - x/3

f^-1 = 4(20 - x)

y/4 = 20 - x

x = 20 - y/4

f(x) = 20 - x/4

f(x) = 20 - 0.25x

f^-1 = x - 7

y = x - 7

x = y + 7

f(x) = x + 7

Mrs. Hinely grows roses. There are 6 roses on each of her 10 rose bushes. How many roses in all are on Mrs. Hinely's rose bushes
diamong [38]
In order to find the total number of roses, we can use multiplication. Since there are 6 roses on each bush, we can say that the answer is: 6+6+6+6+6+6+6+6+6+6. Since multiplication is a way to quickly add the same number, we can use 6*10. This becomes 60. 

Good luck :D
