Answer:
Height of cylinder is [tex]\frac{4}{5}\ ft[/tex].
Step-by-step explanation:
Diameter of cylinder, D = 6 feet
Relation between Radius, R and diameter, D is given by:
[tex]R = \dfrac{D}{2}[/tex]
So, radius, R = [tex]\frac{6}{2} \Rightarrow 3[/tex] feet
Let height of cylinder be [tex]h[/tex] feet.
Formula for volume of cylinder is given by:
[tex]V = \pi R^{2} H[/tex]
Where, R is the radius of base of cylinder
and H is the height of cylinder
We are given that,
[tex]V = \dfrac{36 \pi}{5} ft^{3}[/tex]
Using formula for volume, [tex]V = \pi R^{2} H[/tex]
[tex]\dfrac{36\pi}{5} = \pi \times 3^{2} \times h\\\Rightarrow \dfrac{36\pi}{5} = \pi \times 9 \times h\\\Rightarrow h = \dfrac{4}{5} ft[/tex]
Hence, Height of cylinder is [tex]\frac{4}{5}\ ft[/tex].

Which is the graph of the function f(x) = x3 – x2 – 17x - 15?
Answer with Step-by-step explanation:
We are given that a function
[tex]f(x)=x^3-x^2-17x-15[/tex]
We have to find the graph of the given function.
y-intercept:It is that value of y where the graph cut the y- axis.
Let
[tex]y=f(x)=x^3-x^2-17x-15[/tex]
Substitute x=0
Then, we get
[tex]f(0)=-15[/tex]
y-intercept of the graph=-15
x- intercept: It is that value of x where the graph cut the x- axis.
Substitute y=0
[tex]x^3-x^2-17x-15=0[/tex]
Substitute x=-1
[tex]-1-1+17-15=0[/tex]
Therefore,x=-1 is a solution of given equation.
[tex](x+1)(x^2-2x-15)=0[/tex]
[tex](x+1)(x^2-5x+3x-15)=0[/tex]
[tex](x+1)(x(x-5)+3(x-5))=0[/tex]
[tex](x+1)(x+3)(x-5)=0[/tex]
[tex]\implies x=-1,-3,5[/tex]
Hence, the x-intercept are
-3,-1 and 5

Mario earns money mowing his neighbors' lawns.
The revenue for mowing x lawns is (X) = 25x.
Mario's cost for gas and the mower rental is (x) = 6x + 15.
His profit from mowing x lawns is p(x) = (r- c)(X). What is p(x)?
A. p(x) = 31x+15
B. p(x) = 19x - 15
C. p(x) = 19x+ 15
O D. p(x) = 31x- 15
SUBMIT
Answer:
His profit from mowing x lawns is 19x-15
Step-by-step explanation:
Revenue for mowing x lawns = 25x
Cost for gas and the mower rental = 6x+15
We are supposed to find His profit from mowing x lawns
p(x) denotes His profit from mowing x lawns
Profit = Revenue - Cost
So,p(x)=25x-(6x+15)
p(x)=25x-6x-15
p(x)=19x-15
So, Option B is true
Hence His profit from mowing x lawns is 19x-15

Paul is looking at a detailed plan showing the layout of the extension with the new equipment, He knows the new oven will be 1.5 meters wide and on the plan it measures 7.5 centimeters.
What scale is used on the plan?
Answer:
Scale = 1/200 = 1 : 200
Therefore, 1 centimeter on the plan represent 200 centimeters on the original length.
Step-by-step explanation:
Scale is the ratio of the original object to the drawn plan.
Scale = plan : original
Scale = plan length ÷ original length
Plan length = 7.5 centimeters
Original length = 1.5 meters = 1,500 centimeters
Substituting the values;
Scale = 7.5/1500 = 1/200
Scale = 1 : 200
Therefore, 1 centimeter on the plan represent 200 centimeters on the original length.

The ratio of boys to girls at Jackie Chan high school is 5:3. If there are a total of 250 boys in the school how many girls are in the school?
Answer:
150
Step-by-step explanation:
As the ratio is 5:3 ,
Number of boys / number of girls = 5 / 3
250 / number of girls = 5 / 3
Number of girls = 250 × 3/5
Number of girls = 150
Amber's mean mark on five tests is 80.
Her marks on four of these tests are 68, 81, 74 and 89.
Work out her mark on the fifth test.
Answer:
The answer is 88.
Step-by-step explanation:
68+81+74+89+x/5=80
312+x/5=80
312+x=80*5
312+x=400
x=400-312
x=88
Answer:
88
Step-by-step explanation:
The mean is the total sum of all the marks divided by how many there are.
68+81+74+89=312 Total of 4 tests
80×5 = 400 Total marks on 5 tests
400-312 = 88 Total marks on 5 tests - Total marks on 4 tests = 1 test
68+81+74+89+88 = 400

-8
osy<00
2 sy<00
Answer:
D.
Step-by-step explanation:
(-∞, ∞) is the range of the function y = f(x) = x/2 + 8.
What is a function?A relation is a function if it has only One y-value for each x-value.
The function y = f(x) = x/2 + 8 is a linear function with slope 1/2 and y-intercept 8.
As x varies from negative infinity to positive infinity, the value of f(x) also varies from negative infinity to positive infinity.
Therefore, the range of the function is all real numbers, that is:
y ∈ (-∞, ∞)
In interval notation, this can be written as (-∞, ∞)
Hence, (-∞, ∞) is the range of the function y = f(x) = x/2 + 8.

A bolt is to be made 2.0 cm long with a tolerance of 4%. Set up an equation to solve for the shortest and longest bolt length. Show your original equation and the process used to find the shortest and longest bolt length.
Answer:
The equations are:
[tex]\text{shortest} = \text{length} - \frac{\text{tolerance}}{100}*\text{length}\\\text{shortest} = 2 - \frac{4}{100}*2 = 1.92\\\text{longest} = \text{length} + \frac{\text{tolerance}}{100}*\text{length}\\\text{longest} = 2 + \frac{4}{100}*2 = 2.08\\[/tex]
Step-by-step explanation:
The ideal length of the bolt is 2.0 cm, since it has a tolerance of 4%, this means that length values between [tex]2 + \frac{4}{100}*2[/tex] and [tex]2 - \frac{4}{100}*2[/tex] are acceptable, because by those expressions the length of the bolt will be 4% higher or lower than it's original length. With this in mind let's find it's values:
[tex]\text{shortest} = \text{length} - \frac{\text{tolerance}}{100}*\text{length}\\\text{shortest} = 2 - \frac{4}{100}*2 = 1.92\\\text{longest} = \text{length} + \frac{\text{tolerance}}{100}*\text{length}\\\text{longest} = 2 + \frac{4}{100}*2 = 2.08\\[/tex]
