Answer:
101.1%
Step-by-step explanation:
The two batteries are in the shape of cylinder.
The total surface area of a cylinder
SA = (2πr^2 + 2πrh ) =
For AAA battery
h = 0.8mm
r = 1.9 mm
SA = (2π(1.9)^2 + 2π × 1.9 × 0.8 )
SA = 22.68 + 9.55
SA = 32.23 mm^2
For AA battery
h = 1 mm
r = 2.75 mm
SA = (2π(2.75)^2 + 2π×2.75× 1 )
SA = 47.52 + 17.28
SA = 64.80 mm^2
Increase in SA = 64.80 - 32.23
Increase in SA = 32.57
% increase = increase in SA/AAA × 100
% increase in SA = 32.57/32.23 × 100
% increase in SA = 101.1%
A = (350/13) and B = (400/-13)
The inverse function is:
And g(2) = 212.
<h3>
How to get the inverse function?</h3>
We need to find g(x) such that:
g(h(x)) = x.
We know that:
![h(x) = \frac{\sqrt[3]{x + 4} }{3}](https://tex.z-dn.net/?f=h%28x%29%20%3D%20%5Cfrac%7B%5Csqrt%5B3%5D%7Bx%20%2B%204%7D%20%7D%7B3%7D)
Then our function must be a cubic, multiplied by 3^3 = 27, and then subtracts 4, it is:
As you can see, if you evaluate in h(x), the outcome is x.
Now we can evaluate this in x = 2, we get:
The correct option is C.

Answer:
-(135/31), 60/31
Step-by-step explanation:
y=60/31
x=-(135/31)
42 is your answer since you add your two bases and the divide by 2. after you've done that you multiply your height.
