Answer:

5

Step-by-step explanation:

Alright so this problem is like that other one i did where line RQx2 is equal to line SU

First we set up an equation

x+3=x-2

because line RQ is only 1/2 of line SU we multiple its side by 2 to get the new equation of

x+3=2x-4

step 1 subtract each side by 2x

-1x+3=-4

step 2 subtract each side by 3

-1x=-7

divide each side by -1

x=7

Next we plug in x (7) so 7-2=5

line RQ=5

Write the volume of a cylinder with a base radius 3 m and height 8 m in terms of pi
IRISSAK [1]

Answer:

72π (in terms of pi)

Step-by-step explanation:

V = π·r²·h

Plug in the values.

V = π·3²·8

Solve.

V = 72π

To leave an equation in terms of pi, just square, multiply, and leave pi at the end.

3² = 9·8 = 72

72π

If you need the answer fully simplified, it is 226.19 (rounded up).

11. PLS help!!! the question is attached in the image below
Colt1911 [192]

Answer:

y = 3/2x-5/2

Step-by-step explanation:

We have two points so we can write the equation for the line. (-1,-4) and (3,2)

First we can find the slope by using

m= (y2-y1)/(x2-x1)

m = (2- -4)/(3 - -1)

   =(2+4)/(3+1)

   = 6/4

    = 3/2

Then put the slope into the slope intercept form of the equation

y= mx+b  where m is the slope and b is the y intercept

y = 3/2x+b

We will use the point (3,2) and substitute it into the equation to find b

2 = 3/2(3)+b

2 = 9/2 +b

Subtract 9/2 from each side

4/2 -9/2 = 9/2-9/2 +b

-5/2 = b

y = 3/2x-5/2
