Hey can someone help me and check my answers? thanks <3

Tasya [4]

Remember
x^-m=1/(x^m)
u^-3=1/(u^3)
1/(u^3)=1/125
therefor
u^3=125
u=5

x=-3
easy
y=-3-13
y=-16
correct

normally, y is output
(x,y)
chose al second numbers
0,3 are all acceptable
B and D

y=mx+b
m=-3
y=-3x+b
sub point
(x,y)
(1,-2)
-2=-3(1)+b
-2=-3+b
1=b
y=-3x+1

remember (x,y) you keep swtiching those

A cylindrical container is used to hold drinking water on the sidelines for a football team. The maximum capacity of the contain

wlad13 [49]

To solve this we are going to use the formula for the volume of a cylinder: $V= \pi r^2h$
where
$V$ is the volume of the cylinder in cube centimeters
$r$ is the radius of the cylinder in centimeters
$h$ is the height of the cylinder in centimeters

We know for the problem that volume of our cylinder is 26,460 mL. Since 1 mL = $1cm^3$ , the volume of our cylinder is $26460cm^3$ . We also know for our problem that the height of our cylinder is 60 cm, so $h=60$ . Lets replace those values in our formula and solve for $r$ :
$V= \pi r^2h$
$26460= \pi r^2(60)$
$26460=60 \pi r^2$
$r^2= \frac{26460}{60 \pi }$
$r^2= \frac{441}{ \pi }$
$r= \sqrt{ \frac{441}{ \pi } }$
$r= \frac{21}{ \sqrt{ \pi } }$
$r=11.8$

We can conclude that the radius of the football team's <span>cylindrical container is 11.8 cm</span>
