V=100 inches³
r= 2 inches
V=πr²h100=π2²h
100=π4h
25=πh
h=25/π
h=7.957747 inches

(10-P) Help please, thanks.

The formula of linear equation is:
y1  -  y2 = m(x1  -  x2)
Where
x1 and x2: x coordinates(-1 and 3)
y1 and y2: y coordinates(-2 and 10)
m is the slope

We can then choose a point from the line to find the eqaution.

We need to first find the slope:
\frac{y1 - y2}{x1 - x2}
In this case:
\frac{ - 2 - 10}{ - 1 - 3}   \\ =  \frac{ - 12}{ - 4}  \\  = 3

In this case, as the y2 is given as 1,put (-1,-2) , and the slope(3 )into the eqaution :

y-(-2) = 3(x-(-1))
y+2 = 3(x+1)

Therefore
y + 2 = 3x + 1
is the answer.

Hope it helps!

The larger of the two numbers is 4 more than twice the smaller. The difference of the larger number and the smaller number is 6.
xxMikexx [17]

Answer:

2 and 8

Step-by-step explanation:

Larger number = y

Smaller number = x

---------------------------------

y = 2x+4

y - x = 6 ->  y= x+6

---------------------------------------

x + 6 = 2x + 4

2 = x

y = x+ 6

y = 2 + 6

y = 8

Hope this makes sense!!!!

What is the slope of a line perpendicular to the line whose equation is 3x-3y=54. Fully simplify your answer.​
padilas [110]
Perpendicular = opposite sign and reciprocal slope
Make equation into y = mx + b
Add 3y to both sides
3y + 54 = 3x
Subtract 54
3y = 3x - 54
Divide by 3
y = x - 18
The slope is 1
Make it negative and reciprocal
= -1/1 = -1

Solution: the slope will be -1
