The space that will be on either side if its placed on the pedestal of the cylinder that is 18 inches across will be 4.47 inches.
How to compute the dimension?It should be noted that the volume of a cylinder is given as:
= πr²h
We'll then slot the values given into the formula. This will be:
Volume = πr²h
1130.97 = (3.14 × r² × 18)
1130.97 = 56.52r²
r² = 1130.97/56.52
r² = 20
r = ✓20
r = 4.47
In conclusion, the space will be 4.47 inches.

Is a triangle with the side lengths 4 feet, 7. 5 feet, and 8. 5 feet a right triangle? Why or why not?
Answer:
Yes
Step-by-step explanation:
You can test if a triangle is right-angled by using Pythagoras' Theorem.
So:
[tex]4^2 + 7.5^2 = 8.5^2[/tex]
16 + 56.25 = 72.25

The area of a rectangle is (x4 4x3 3x2 – 4x – 4), and the length of the rectangle is (x3 5x2 8x 4). if area = length × width, what is the width of the rectangle? x 1 x – 9 x 4 x – 1
Answer:
Area = x4 + 4x3 + 3x2 - 4x - 4
Length = x3 +5x2 + 8x + 4
Width = Area / Length.
Performing long division with polynomial.
x4 + 4x3 + 3x2 - 4x - 4 / x3 + 5x2 + 8x + 4 = x-1
Width = x-1
Step-by-step explanation:
The value of the width of the rectangle is,
⇒ (x - 1)
We have to given that;
In a rectangle;
Area = x⁴ + 4x³ + 3x² - 4x - 4
Length = x³ +5x² + 8x + 4
We know that;
Width = Area / Length.
Hence, Performing long division with polynomial.
Width = x⁴ + 4x³ + 3x² - 4x - 4 / x³ +5x² + 8x + 4
= x - 1
Thus, The value of the width of the rectangle is,
⇒ (x - 1)

What are the vertex and x-intercepts of the graph of the function given below?
y=x²-2x-48
O A. Vertex: (-1, -21); intercepts: x = 6,4
B. Vertex: (1, -40); intercepts: x = 6,7
C. Vertex: (1,-49); intercepts: x = 8,-6
D. Vertex: (0, 0); intercepts: x= -4, 6
SUBMIT
Answer:
C. Vertex: (1,-49); intercepts: x = 8,-6Step-by-step explanation:
x²-2x-48 = (x²-2x +1) - 1 - 48
= (x - 1)² - 49
Then
The vertex is (1 , - 49)
==================
x²-2x-48 = 0
⇔ (x - 1)² - 49 = 0
⇔ (x - 1)² = 49
⇔ x - 1 = 7 or x - 1 = -7
⇔ x = 8 or x = -6
Then
intercepts: x = 8,-6
Suppose a town has a population of 5,000 residents but that the population is decreasing by 200 people each year. Write a linear function to represent the population of the town in terms of the numbers of years. After how many years will the town have a population of 1,800? When will the town have only 400 residents?
Answer:
it will take 16 years to reach a population of 1800 and in 23 years the population will be 400.
Step-by-step explanation:
population: 5000
population decreasing: 200x
y=5000-200x
(1800-5000)/-200
(400-5000)/-200

A 1,500-gallon tank contains 200 gallons of water. Water begins to run into the tank at the rate of 75 gallons
per hour. When will the tank be full but not overflowing?
Answer:
17hrs (a little more)
Step-by-step explanation:
The tank is 1500 gallon capacity, it already contains 200 gallons.
1500-200=1300
Now, you have to figure how many hrs it will take at 75 gallons / hr to reach the additional 1300 gallons.
1300÷75= 17.33
It says full, but not overflowing. So I would say around 17hrs
