Answer:

? = 35

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan ? = opp /adj

tan ? = 33/48

Take the inverse tan of each side

tan ^ -1 ( tan ? ) = tan ^ -1 ( 33/48)

? =34.50852299

? = 35

What is the slope of a line perpendicular to a line with slope –9?

7nadin3 [17]

Answer:

The answer is 1/9.

Step-by-step explanation:

When solving for the slope of a perpendicular line to a given, you have to flip the opposite reciprocal.

First take the number and flip the reciprocal, in this case -9 turns into -1/9.

Then flip the sign, like making a negative to a positive or a positive to a negative. In this case make -1/9 into 1/9

Therefore the answer is 1/9.

What’s the rate of change of the table above? A) -1/3 B) 1/2 C) -1/4 D) 1/5

insens350 [35]

answer is option D

because you can divide them like

$\frac{2}{10} = \frac{1}{5} \\ \\ \frac{4}{20} = \frac{1}{5} \\ \\ \frac{6}{30} = \frac{1}{5} \\ \\ \frac{8}{40} = \frac{1}{5}$

so the option is D

Find the slope of the line graphed in the diagram and choose the correct answer from the choices below. The two intercepts are (

kolezko [41]

1.2 is the slope of the line graphed in the given diagram

Step-by-step explanation:

We can use the given points (0, 3) and (-2.5, 0) to solve.

Slope formula is given by

$\text { slope, } m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Given two intercepts:

$\left(x_{1}, y_{1}\right)=(0,3) \text { and }\left(x_{2}, y_{2}\right)=(-2.5,0)$

By substituting these in the slope equation, we get

$\text { slope, } m=\frac{0-3}{-2.5-0}=\frac{-3}{-2.5}=\frac{3}{2.5}=1.2$
