Answer:
11860.22 rev/hour
Step-by-step explanation:
The diameter if a cylinder, d = 21.02 inches
Radius, r = 10.51 inches
or
r = 0.875 feet
The linear speed of a point on the cylinder's surface is 18.12 ft/sec.
We need to find the angular speed of the cylinder.
The relation between the linear speed and the angular speed is given by :
[tex]v=r\omega[/tex]
Where
[tex]\omega[/tex] is angular speed
[tex]\omega=\dfrac{v}{r}\\\\\omega=\dfrac{18.12}{0.875}\\\\\omega=20.7\ rad/s[/tex]
or
[tex]\omega=11860.22\ rev/hour[/tex]
So, the required angular speed of the cylinder is 11860.22 rev/hour.

Answer:
Step-by-step explanation:
the total price for clothes= 24.95+14.95=39.90
sales tax 39.90*9.5/100=3.79
the total paid to the clerk will be=39.90+3.79=43.69

at 6:00 a.m., the temperature is 58°. At 2:00 p.m., temperature is 76°. Find the rate of change in degrees per hour during this time.
Answer:
The rate of change is of 2.25 degrees per hour.
Step-by-step explanation:
The rate of change in degrees per hour is given by by the change in temperature divided by the change in time(by number of hours).
In this question:
From 6 am to 2 pm, there are 12 - 6 + 2 - 0 = 6 + 2 = 8 hours
The change in temperature was of 76 - 58 = 18º
Rate of change:
18º/8 = 2.25º
The rate of change is of 2.25 degrees per hour.
A clinical psychologist is the primary therapist for 12 patients. She randomly selects a sample of 3 patients to be in her study. How many different samples of this size can be selected from this population of 12 patients using theoretical sampling and experimental sampling?
(a) theoretical sampling
samples
(b) experimental sampling
samples
Answer:
a)[tex]X=1728[/tex]
b)[tex]X'=220[/tex]
Step-by-step explanation:
From the question we are told that
Population size N=12
Sample size n=3
a)Generally using theoretical sampling we can solve mathematically
[tex]X=N^n[/tex]
[tex]X=12^3[/tex]
[tex]X=1728[/tex]
b)Generally using experimental sampling we can solve mathematically
[tex]X'=^NC_n[/tex]
[tex]X'=^1^2C_3[/tex]
[tex]X'=220[/tex]

Given the function g(x) = x2 + 10x + 19, determine the average rate of change of
the function over the interval -9 < x < 1.
Answer:
The average rate of change of the function over the interval is of 2.
Step-by-step explanation:
Suppose we have a function f(x), over an interval (a,b).
It's average rate of change over the interval is given by:
[tex]A = \frac{f(b) - f(a)}{b - a}[/tex]
In this question:
[tex]g(x) = x^2 + 10x + 19[/tex]
Over the interval -9 < x < 1, so [tex]a = -9, b = 1[/tex]. So
[tex]A = \frac{g(1) - g(-9)}{1 - (-9)} = \frac{g(1) - g(-9)}{10}[/tex]
We have that:
[tex]g(1) = 1^2 + 10(1) + 19 = 1 + 10 + 19 = 30[/tex]
[tex]g(-9) = (-9)^2 + 10(-9) + 19 = 81 - 90 + 19 = 10[/tex]
So
[tex]A = \frac{30 - 10}{10} = \frac{20}{10} = 2[/tex]
The average rate of change of the function over the interval is of 2.

Step-by-step explanation:
Concrete workers are busy preparing to pour a rectangular patio on the rear of Miguel's new house. The workers have laid out, using boards, what appears to be rectangle to frame where the concrete will go.
What could the workers do to ensure the patio is really rectangular before pouring the concrete?
Answer:
See Explanation below.
Step-by-step explanation:
What the workers can do to ensure the patio is truly rectangular, before pouring the concrete, is to measure the length of the sides of the patio.
This requires full knowledge of the physical properties of a rectangle.
The opposite sides of a rectangle (the two sides which go in the same direction or which are parallel to each other) are equal in length and one set of parallel sides must be longer than the other set of parallel sides.
These are the conditions that the patio must satisfy, to be truly rectangular.
Once the workers have made sure of this, they can go ahead and pour the concrete.

Step-by-step explanation:
The length of a living room is 12 feet and its width is 10.5 feet. The length of the room is being expanded by x feet.
A. Write an expression to represent the new area of the living room in square feet.
B. Expand the expression.
Answer:
A) A= 10.5(12 +x)
B) A= 10.5x +126
Step-by-step explanation:
A) Length of living room= 12 ft
Width= 10.5 ft
Since the length expanded by x ft,
New length of living room= (12 +x) ft
Area= length ×width
Let the new area of the living room be A ft².
A= 10.5(12+x)
B) To expand the expression, multiply 10 to each term and constant in the bracket on the right hand side of the equation.
A= 10.5(12 +x)
A= 10.5(12) +10.5x
A= 126 +10.5x
