<u>Answer:</u>

-2/3

<u>Step-by-step explanation:</u>

We are to find the slope of a line which is perpendicular of a line with an equation 2y=3x-1.

We know that the slope of line which is perpendicular to another line is the negative reciprocal of that perpendicular line.

So writing the given equation of a line in the slope intercept form:

2y=3x-1 ---> y=\frac{3}{2} x-\frac{1}{2}

Here the slope of this line is \frac{3}{2} so the slope of a line which is perpendicular to the given line will be -\frac{2}{3}.

Given f ( x ) = 1 x + 10 , find the average rate of change of f ( x ) on the interval [ 8 , 8 + h ] . Your answer will be an exp
son4ous [18]

Answer: 1

Step-by-step explanation:

f(8+h)=8+h+10=18+h\\\\f(8)=8+10=18

So, the average rate of change is:

\frac{(18+h)-18}{(8+h)-8}=\frac{h}{h}=\boxed{1}

The question is wrong, the expression will not be in terms of h since it is a linear function.

Find the surface area of the prism
Anastasy [175]

slated surface

17 × 20 = 340

2 triangle sides

2 × 8 × 15 ÷ 2 = 120

backside

8 × 20 = 160

bottom

15 × 20 = 300

sum all of it

340 + 120 + 160 + 300 = 920
