If you think about it, an octagon is made up of 8 triangles. So you first find the area of one triangle then multiply it by 8 for the total area:
A=1/2bh
A=1/2(9.9)(12)
A=59.4

59.4 x 8= 475.2

Therefore the total area for the octagon should be 475.2 units^2

Hope this helps !

Find the number c that satisfies the conclusion of the Mean Value Theorem on the given interval. (Enter your answers as a comma-

coldgirl [10]

Answer:

c is all the points in the open interval (0,25)

Step-by-step explanation:

Here given is a function

$f(x) =x$ , which is continuous in the interval [0,25] and differentiable in (0,25)

Mean value theorem says there exists at least one c in the interval (0,25) such that

$f'(c) = \frac{f(25)-f(0)}{25-0}$

We have

$f(25)=25 and f(0) = 0\\f'(c) = 1$

For the given function

$f'(x) =1$

Hence we have c equals all the points in the open interval (0,25)

If f(x) = 6(9)^x then f(1/2) =?

Oksi-84 [34.3K]

F(x) = 6(9)^x

f(1/2) = 6(9)^(1/2)

f(1/2) = 6(9)^(0.5)

f(1/2) = 6*(9^0.5) 9^0.5 = √9 = +3 or -3.

f(1/2) = 6*3 = 18 or 6*-3 = -18

f(1/2) = 18 or -18

Hope this helps.
