Please hurry I will mark you brainliest <br> Find the surface area

erastova [34]

Triangle area = 8 x 3/2

= 12

12 x 2 = 24cm^2 for 2 triangles

Height of rectangle must be found, so use pythag on triangle

a^2+ b^2 = c^2

16 + 9 =c^2

C=5

A= 5 x 12

= 60

60 x 3 triangles in total is 180cm^2

180cm^2 + 24cm^2 = 204cm^2

Ans: 204cm^2

Which expression can be used to determine the average rate of change in f(x) over the interval mc001-1.jpg

Mrac [35]

The average rate of change of a function f(x) over an interval (a, b) is given by
$\frac{f(b)-f(a)}{b-a}$

Therefore, given a function, f(x), over an interval (2, 9), the average rate of change of the function can be found using the expression
$\frac{f(9)-f(2)}{9-2}$
