SA = 2bA (base area) + LA (lateral area)

bA = r^2*pi = 13^2pi = 169pi cm^2

LA = 2r*pi*h = 2*13*pi*88,4 = 2298,4pi cm^2

SA = (2*169pi)+2298,4 pi = 338pi+2298,4pi = 2636,4pi

20 points! Write an exponential function in the form y=ab^x that goes through points (0, 8) and (2, 200)

alexandr402 [8]

Answer:

$y=8(5)^x$

Step-by-step explanation:

We want an exponential function that goes through the two points (0, 8) and (2, 200).

Since a point is (0, 8), this means that y = 8 when x = 0. Therefore:

$8=a(b)^0$

Simplify:

$a=8$

So we now have:

$y = 8( b )^x$

Likewise, the point (2, 200) tells us that y = 200 when x = 2. Therefore:

$200=8(b)^2$

Solve for b. Dividing both sides by 8 yields:

$b^2=25$

Thus:

$b=5$

Hence, our exponential function is:

$y=8(5)^x$

These two angles are vertical angles. Vertical angles are congruent, so you have to make an equation.
