Through:(-5, -4), perp. to y = 5x – 5

1 answer:

6 0

Perpendicular means reverse reciprocal of the slope. Here the slope is 5 so the slope of the perp line is -1/5. Now you have y = -1/5 + x so just plug in -5 as x and -4 as y and you get -4 = -1/5 - 5

Sin 33°= 7/x A. 5.9 B. 12.9 C. 10.8 D. 8.3

DanielleElmas [232]

Answer:

Step-by-step explanation:

The equation to solve is:

$Sin(33)=\frac{7}{x}$

Sin 33 has a value in the calculator. We simply cross multiply and do algebra and solve:

$Sin(33)=\frac{7}{x}\\Sin(33)*x=7\\x=\frac{7}{Sin(33)}\\x=12.85$

Rounding to 1 decimal place, we have:

12.85 = 12.9

Answer choice B is right.
