The answer is 1206 cm. The formula for the volume of this cone is 1/3 • 3.14 • 12(2) • 8.
Which gives you 1205.76 which is rounded up to 1206.

The (2) means the second power so it’s 12 to the second power.

What is the yintercept of f(x) =(1/2)^x<br> ?

Anestetic [448]

$\text{Find the y-intercept:}\\\\\text{To fidn the y-intercept, we would have to plug in 0 to x. Since the y-intercept}\\\text{exists whenever x is equal to 0}\\\\\text{Solve:}\\\\f(x)=(\frac{1}{2})^0\\\\\text{We know that whenever the exponent is 0, it equals to 1}\\\\f(x)=1\\\\\text{Therefore, this makes the y-intercept 1.}\\\\\text{Answer is stated as a point on the graph}\\\\\boxed{(0,1)}$
