Answer:
<h2>282.857 in²</h2>
Step-by-step explanation:
The formula of a surface area of a cylinder:

r - radius
H - height
We have:
r = 5 in
H = 4 in
Substitute:


Substitute:

Answer: y = 1.231x + 1.385,
= .703, r = .839
Step-by-step explanation:
If you plug these points into a TI-84 and use the linear regression function, you'll get this result.
Answer:
x=-3 y=17 (-3;17)
Step-by-step explanation:
-3x+8-y=0
-5x+2-y=0
-2x-6=0
So: x=-3
While....by substituting: y=17
Answer:
y = x
Step-by-step explanation:
Find the slope using rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-8 - 0) / (-8 - 0)
-8 / -8
= 1
So, the slope is 1.
Plug in the slope and a point into y = mx + b and solve for b:
y = mx + b
-8 = 1(-8) + b
-8 = -8 + b
0 = b
Plug in the slope and y intercept into y = mx + b
y = mx + b
y = 1x + 0
y = x
So, the equation of the line is y = x
X=27
81 = 3x= 27
So x means 27
