Answer:
4:25
Step-by-step explanation:
Given that,
r₁ = 15 inches, r₂ = 6 inches
The area of the cylinder is given by :
The ratio of surface areas of two cylinders,
Hence, the required ratio is 4:25.
Answer:
Step-by-step explanation:
2x + 3 = 4x - 5
-2x + 3 = -5
-2x = -8
x = 4
Answer: 1
A plane is uniquely defined by 3 distinct points. Think of a stool with 3 legs. Each part of the leg that makes contact with the ground allows the stool to stay stable. It turns out that that extra 4th leg may make the stool wobbly which is why 3 legs are preferred.

Answer: A) linear function</h3>
Each time x goes up by 2, y decreases by 4
This indicates we have a linear function. The slope in this case would be
m = rise/run = (change in y)/(change in x) = -4/2 = -2
The y intercept can be found by following these steps
y = mx+b
0 = -2(5)+b
0 = -10+b
10 = b
b = 10
Therefore, the equation of this line is y = -2x+10. Plug in something like x = 1 and it should lead to y = 8. The same applies for any other column of x,y values.
