Can someone help me with these questions

Mathematics
1 answer:
Varvara68 [4.7K]3 years ago
5 0

Answer:

1.) can not be found

2.)V=11403.98

3.)

Step-by-step explanation:

volume = π r×r × H

r = Radius

H = height

π = 3.14

the first one does not have a radius so therefore we can NOT find the volume

the second one is π×(11×11) ×30 =11403.98

the 3rd one is π× (10×10) ×5 =1570.79

hope this helped

For question 4: you have to do (y2 - y1) divided by (x2 - x1) to get the rise over run...

5-2
——. = 3/4
11 - 7


For question 5: input the values of x,y and the gradient into the equation of a line.....

y = mx+ c

-8 = 3(-2) + c

-8 = -6 + c

-2 = c

therefore:

y = 3x - 2

Hope this helps! Any questions let me know :)

Solving for y. - y = -2x -5
Effectus [21]

Answer:

y = 2x+5

Step-by-step explanation:

Add y on both sides, this cancels out the y on the left side

add 2x and add 5 on both sides, this cancels out the -2x and the -5 on the left side.

<u>OR </u>

Divide/Multiply both sides by -1, as it will cancel out the negatives as two negatives make a positive.

If you needed a value for y, more info is needed.

hope this helps (:

please rate, thanks !
