4 0

Answer:

The coefficient is 1

Step-by-step explanation:

There is an imaginary 1 in front of variables that becomes the coefficient if there isn't already a number there. If it was 5x squared, the coefficient would be 5.

the volume of a cylinder is given by the formula v=3.14r^2h, where r is the radius of the cylinder and h is the height. suppose

photoshop1234 [79]

we know that

The volume of a cylinder is given by the formula

$V=3.14 r^{2} h$

where

r is the radius of the cylinder

h is the height of the cylinder

in this problem

$r=x+8\\h=2x+3$

Substitute the values in the formula above

$V=3.14*(x+8)^{2}*(2x+3)$

$V=3.14*(x^{2}+16x+64)*(2x+3) \\ V=3.14 *(2x^{3} +3x^{2} +32x^{2} +48x+128x+192)\\ V=3.14*(2x^{3} +35x^{2} +176x+192)$

therefore

<u>the answer is</u>

The volume of the can is equal to

$V=3.14 *(2x^{3} +35x^{2} +176x+192)\ units ^{3}$

Find ST if S(-3, 10) and T(-2, 3)

FrozenT [24]

We have the following points and their coordinates:

$\begin{gathered} S(-3,10), \\ T(-2,3). \end{gathered}$

We must compute the distance ST between them.

The distance ST between the two points is given by:

$ST=\sqrt[]{(x_S-x_T)^2+(y_S-y_T)^2_{}},$

where (xS,yS) are the coordinates of the point S and (xT,yT) are the coordinates of the point T.

Replacing the coordinates of the points in the formula above, we find that:

$\begin{gathered} ST=\sqrt[]{(-3_{}-(-2)_{})^2+(10_{}-3_{})^2_{}}, \\ ST=\sqrt[]{1^2+7^2}, \\ ST=\sqrt[]{50}\text{.} \end{gathered}$

Answer: ST = √50
