The total surface area of a cylinder with height 5 in. is given by the function g(x) = 2πx2 + 10πx, where x is the radius, and the function f(x) = 10πx gives the surface area of the side of the cylinder. Which combined function gives the total surface area of the two bases of the cylinder? A. f + g B. f – g C. g – f D. f · g
Answer:
C. g - fStep-by-step explanation:
Total surface area of a cylinder with height 5 is:
A = 2πrh + 2πr² = 10πr + 2πr²If we substitute r with x, we get:
g(x) - full surface areaf(x) - surface areaTotal surface area of two bases:
g - f = 2πx² + 10πx - 10πx = 2πx²Correct choice is C

Complete the equation of this circle:
(x - [ ? ])2+(y - [ ])2= []
The complete equation of the circle graphed is (x - 2)² + (y + 2)² = 9
Determining the equation of the circle graphedFrom the question, we have the following parameters that can be used in our computation:
The circle
Where, we have
Center = (a, b) = (2, -2)
Radius, r = 3 units
The equation of the circle graphed is represented as
(x - a)² + (y - b)² = r²
So, we have
(x - 2)² + (y + 2)² = 3²
Evaluate
(x - 2)² + (y + 2)² = 9
Hence, the equation is (x - 2)² + (y + 2)² = 9

Ryan's take-home pay is $2,500 each month. The amount for gas is $125. Calculate the percentage Ryan uses on gas from his take-home pay. please help!! O^O
Answer: 5%
Step-by-step explanation:
Since Ryan's take-home pay is $2,500 each month and the amount for gas is $125.
The percentage that Ryan uses on gas from his take-home pay will be:
= Amount used on gas / Take home pay × 100
= 125/2500 × 100
= 1/20 × 100
= 5%
He used 5% on gas.

A triangle has angle measures of 47 degrees and 92 degrees. What is the measure of the third angle?
Answer:
The missing angle is 41 degrees
Step-by-step explanation:
First of all, a triangle is measured at 180 degrees in total
To find the missing measurement for the third angle, add the 47 and 92 degrees together which would equal 139 degrees.
47+92=139 degrees
Next just subtract 139 from 180 to get your answer.
180-139=41 degrees
The answer is 41 degrees

can someone please double check this for me?
Answer:
False
True
False
True
Step-by-step explanation:
The 4th option should be correct because the y-intercept on A is greater than the one in B,
A: y = -1/3x + 0 (usually when the y-intercept ain't appearing it means it's 0).
B: y = -1/3 - 2
As we know 0 is greater than -2 because it's closer to being a positive number, so 0 is not positive or negative; 0 is greater than any negative number but smaller than any positive numer so,
0 > -2.
Therefore the last option is true.

Recall the volume of a pyramid is:
V = 1/3(bh)
We are given the volume and side length of the base. Find the area of the base:
A = s²
A = (5xy²)² = 25x²y⁴
Plug in the solved for base:
125x³y³ = 1/3(25x²y⁴)h
To isolate for h, begin by multiplying both sides by 3:
375x³y³ = (25x²y⁴)h
Divide both sides by 25x²y⁴. Use the following exponent property:
xᵃ / xᵇ = xᵃ⁻ᵇ
Thus:
375x³y³ / 25x²4⁴ = 15x/y.
The height must be equal to:

Let f(x) = 7x² + 19x + 21 and g(x) = 4x² + 4x + 3 . Identify the solution(s) of f(x) = g(x).
Answer:

Step-by-step explanation:
7x² + 19x + 21 = 4x² + 4x + 3
combine like terms:
3x² + 15x + 18 = 0
3(x² + 5x + 6) = 0
(x + 3)(x + 2) = 0
