1 answer:

6 0

y^8 = 4
y^7 = 3/x

y(y^7) = 3/x(y)
y^8 = 3y/x

3y/x = 4
3y = 4x
y = 4x/3

Answer: (A)

Answer:

$\displaystyle -\frac{13}{10}$

Step-by-step explanation:

To solve this problem, first you have to use the slope formula of $\displaystyle \frac{y_2-y_1}{x_2-x_1}$ .

y2= (-7)

y1=6

x2=4

x1(-6)

Solve.

$\displaystyle \frac{(-7)-6}{4-(-6)}=\frac{-13}{10}=\boxed{-\frac{13}{10}}$

Therefore, the correct answer is -13/10.

Step-by-step explanation:

$tan \: 48 \degree = \frac{x}{61} \\ \\ 1.11 = \frac{x}{61} \\ \\ x = 1.11 \times 61 \\\\ x = 67.7 feet\:$

RP = 67.7 feet
