Amanda makes colored paper cone cups to serve nuts at a charity event. The height of each paper cone is 15 centimeters, and the

allsm [11]

Answer:

$V=261.80 \ cm^3$

Step-by-step explanation:

-The volume of a cone is given by the formula:

$V=\pi r^2 \frac{h}{3}$

Where:

r is the cone's radius.
h is the cone's height.

#We substitute for r and h in the formula to solve for V:

$V=\pi r^2 \frac{h}{3}\\\\=\frac{1}{3}\pi \times 5^2\times 10\\\\=261.80\ cm^3$

Hence, the each cone's volume is $261.80 \ cm^3$

Given the function g(x)= -x^2 + x + 5, determine the average rate of change of the function over the interval -4 ≤ x ≤ 3.

OleMash [197]

Answer:

The average rate of change is 2.

Step-by-step explanation:

We are given the function:

$g(x)=-x^2+x+5$

And we want to find the average rate of change over the interval:

$-4\leq x\leq 3$

The average rate of change is synonymous with the slope. So, we will evaluate the function at its endpoints and find the slope between them.

Our first endpoint is given by:

$g(-4)=-(-4)^2+(-4)+5=-15$

And our second endpoint is given by:

$g(3)=-(3)^2+(3)+5=-1$

This gives us two points (-4, -15) and (3, -1). The average rate of change will be the slope between them. Thus:

$\displaystyle ARC=\frac{-1-(-15)}{3-(-4)}=\frac{14}{7}=2$

The average rate of change is 2.

The length of a rectangle is 1ft less than 3 times the width. There is 310 ft squared.Find the dimension of the rectangle.

lozanna [386]

Answer:310

Step-by-step explanation:

l=-1+3w

l=3w-1

l*w=310

(3w-1)*w=310

3w^2-w-310=0

w= 31/3

w= 10 1/3

l=31/3*3-1

l=30

30*31/3=10*31=310
