Step-by-step explanation:drum = cylinder
d = 2r => r = d/2 = 22in/2 = 11 in
h = 16 in
V = π·r²·h
= 3.14·(11in)²·16in
= 3.14·121in²·16in
= 6079, 04 in³
≈ 6079 in³

What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have a graph shown in the picture.
From the graph, we can see that:
The minimum value = -0.75
The maximum value = 0.75
The amplitude = 0.75
And the graph of the function:
y = 0.75cosx
Where y ∈ [-0.75, 0.75]
Thus, the minimum value of the graph is -0.75 and maximum value is 0.75, amplitude is 0.75, and function for the graph is y = 0.75cosx.

A group of 59 randomly selected students have a mean score of 29.5 with a standard
deviation of 5.2 on a placement test. What is the 90% confidence interval for the mean
score, ", of all students taking the test?
Answer:
[tex]29.5-1.671\frac{5.2}{\sqrt{59}}=28.37[/tex]
[tex]29.5+1.671\frac{5.2}{\sqrt{59}}=30.63[/tex]
And we can conclude that the true mean for the scores are given by this interval (28.37; 30.63) at 90% of confidence
Step-by-step explanation:
Information given
[tex]\bar X = 29.5[/tex] represent the sample mean
[tex]\mu[/tex] population mean
s= 5.2 represent the sample standard deviation
n=59 represent the sample size
Confidence interval
The confidence interval for the true mean is given by the following formula:
[tex]\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}[/tex] (1)
The degrees of freedom are given by:
[tex]df=n-1=59-1=58[/tex]
The Confidence interval is 0.90 or 90%, the significance is [tex]\alpha=0.1[/tex] and [tex]\alpha/2 =0.05[/tex], and the critical value is [tex]t_{\alpha/2}=1.671[/tex]
Now we have everything in order to replace into formula (1):
[tex]29.5-1.671\frac{5.2}{\sqrt{59}}=28.37[/tex]
[tex]29.5+1.671\frac{5.2}{\sqrt{59}}=30.63[/tex]
And we can conclude that the true mean for the scores are given by this interval (28.37; 30.63) at 90% of confidence

Solve the system of equations.
5x + y = 9
3x + 2y = 4
Answer:
(2,-1)
Step-by-step explanation:
Multiply first equation by 2:
10x + 2y = 18
Subtract the second equation from this so that the 2y terms cancel:
10x - 3x = 18 - 4
7x = 14
x = 2
Plug into first equation to find y:
5(2) + y = 9
10 + y = 9
y = -1
The answer is (2,-1)

Write an equation that is perpendicular to y=4x- 10 and goes through the point (4,2)
Answer:
y = (-1/4)x + 3
Step-by-step explanation:
The slope of our equation is 4, so to find the slope of the perpendicular equation, we have that:
m1 * m2 = -1
Where m1 is the slope of the first equation and m2 is the slope of the perpendicular equation.
So, we have that:
4 * m2 = -1
m2 = -1/4
So the second equation is y = (-1/4)x + b
If the second equation goes through the point (4,2), for x = 4 we have y = 2, then:
2 = (-1/4)*4 + b
2 = -1 + b
b = 3
So the perpendicular equation is:
y = (-1/4)x + 3
What operation could you use to find how many centimeters are in 3 meters?
Complete the explanation and the conversion of 3 meters to centimeters.
The operation needed is?
because there are
centimeters in 1 meter.
3 meters?
centimeters.
Answer:
300 centimeters ( cm)
Step-by-step explanation:
The operation is "multiply by 100 the numbers of meters because there are 100 cm in 1 m "
1m=100 cm
3m=3*100 cm=300 cm
There are 100 centimeters in a meter, resulting in 300 centimeters.
The operation needed to convert meters to centimeters is multiplication because there are 100 centimeters in 1 meter. To convert 3 meters to centimeters, you simply multiply 3 meters by the conversion factor of 100 centimeters per meter.
Therefore:
3 meters × 100 centimeters/meter = 300 centimeters
Using this operation and knowing the conversion factor, we find that 3 meters is equal to 300 centimeters.

Determine the intercepts of the line.
The x-intercept of the graph is (0.3, 0).
The y-intercept of the graph is (0, 0.4).
We have,
The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
The intercepts are:
The x-intercept is the point of the line when y = 0,
The y-intercept is the point on the line when x = 0.
Now,
Apply the intercepts concept on the given graph.
From the graph,
The point when x = 0 is 0.4.
The point when y = 0 is 0.3.
Thus,
The x-intercept of the graph is (0.3, 0).
The y-intercept of the graph is (0, 0.4).

Convert this equation to slope-intercept form:
25x + 10y = 1,000
Answer:
y = -2.5x +100
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
We need to solve for y
25x+ 10y =1000
Subtract 25x from each side
25x-25x+10y = -25x +1000
10y = -25x+1000
Divide each side by 10
10y/10 = -25x/10 +1000/10
y = -2.5x +100
Answer:
y = -2.5x + 100
Step-by-step explanation:
25x + 10y = 1,000
10y = -25x + 1000
y = -2.5x + 100
Find the radius of sphere with a volume of 1372π/3 cubic feet.
Answer:
The radius of the sphere is 7m
Step-by-step explanation:
Given
Volume of a sphere = 1372π/3 m³
Required
The radius.
The volume of a sphere is calculated using the following formula.
V = 4/3 πr³
Where V = volume of the sphere and r represents it's radius.
By substitution;
1372π/3 = 4/3 πr³
Multiply both sides by 3
1372π = 4πr³
Divide through by 4
343π = πr³
Divide through by π
343 = r³
Take cube root of both sides.
r = 7.
Hence, the radius of the sphere is 7m
