If the length of the radius and the height of a right circular cylinder are both tripled to form a larger cylinder, what is the ratio of the volume of the larger cylinder to the volume of the smaller cylinder? (Note: The two cylinders are said to be "similar.")
Answers
Answer:
The ratio of the volume of the larger cylinder to the volume of the smaller cylinder is 27:1
Step By Step Explanation:
Volume of the smaller cylinder(V1)=π(r^2)h
Volume of the larger cylinder(V2)=π(r^2)h
=π(3r)^2*3h
=π*9(r^2)*3h
=27π(r^2)h
The ratio of the volume of the larger cylinder to the volume of the smaller cylinder is 27π(r^2)h/π(r^2)h i.e. 27:1

Given f z please help
Answers
Answer:
z = -11, z = -2
Step-by-step explanation:
Given that, ([tex]f(z)=\sqrt{z+27} -z[/tex]) and ([tex]f(z)=7[/tex]), set up an equation that puts the first value of ([tex]f(z)[/tex]) equal to the other given value of the function.
[tex]f(z)=\sqrt{z+27}-z=7[/tex]
Use inverse operations to solve,
[tex]\sqrt{z+27}-z=7\\\\\sqrt{z-27}=7+z\\\\z+27 = (7+z)^2\\\\z + 27 = 49+14z+z^2\\ -(27+z)\\\\0 = z^2+13z+22[/tex]
Factor,
[tex]0=(z+11)(z+2)[/tex]
Solve using the zero product property, the zero product property states that any number times zero equals zero;
[tex]z=-11,z=-2[/tex]
Answer:
Then solve the rest using the quadratic formula

The Robotics Manufacturing Company operates an equipment repair business where emergency jobs arrive randomly at the rate of three jobs per 8-hour day. The company's repair facility is a single-server system operated by a repair technician. The service time varies, with a mean repair time of 2 hours and a standard deviation of 1.5 hours. The company's cost of the repair operation is $28 per hour. In the economic analysis of the waiting line system, Robotics uses $35 per hour cost for customers waiting during the repair process. What are the arrival rate and service rate in jobs per hour
Answers
Answer:
The correct answer is:
[tex]\lambda=0.375 \ jobs \ per \ hour[/tex][tex]\mu=0.5 \ jobs \ per \ hour[/tex]Step-by-step explanation:
The given values are:
Service time varies,
Repair time = 2 hours
Standard deviation = 1.5 hours
Robotics uses per hour cost,
= $35
Company's cost per hour,
= $28
(a)
⇒ Arrival rate = Jobs per hours
then,
= [tex]\frac{8 \ hours}{3 \ jobs}[/tex]
= [tex]2.666 \ hours \ per \ job[/tex]
The jobs per hour will be:
⇒ [tex]\lambda=\frac{1}{2.666}[/tex]
[tex]=0.375[/tex]
(b)
⇒ Service rate = jobs per hour
then,
μ = [tex]\frac{1 \ repair \ job}{2 \ hours}[/tex]
= [tex]0.5 \ jobs[/tex]
You are asked to draw a triangle with side lengths of 10 inches and 13 inches. What is the longest whole number length that your third side can be?
Answers
Answer:
22
Step-by-step explanation:
10 plus 13 equals 23, so if it is more than that than the lines wont be able to connect. if it is 23 exactly, the triangle will be a stright line, not a triangle, so it is 22.
Answer:
22
Step-by-step explanation:
triangle inequality theorem:
10 + 13 > x
x < 23
10 + x > 13
x > 3
third side: 3 < x < 23

The water diet requires one to drink two cups of water every half hour from when one gets up until one goes to bed, but otherwise allows one to eat whatever one likes. Four adult volunteers agree to test the diet. They are weighed prior to beginning the diet and after six weeks on the diet. The weights (in pounds) are
Person 1 2 3 4
Weight before the diet 180 125 240 150
Weight after six weeks 170 130 215 152
For the population of all adults, assume that the weight loss after six weeks on the diet (weight before beginning the diet minus weight after six weeks on the diet) is normally distributed with mean (µ). When testing the claim that the diet leads to weight loss after six weeks for all adults given that α=0.05, do you reject or fail to reject the Null Hypothesis, why or why not?

A research analyst for a car rental agency found that the probability distribution function for the age of the rental car (in years) is a straight line. The line decreases from the point (0, h) to the point (10, 0). None of the rental cars are older than 10 years. Enter your answers as decimals. 7(a). What is the height for the line when the age of the car is zero?
Answers
Answer:
10 years
Step-by-step explanation:
Given
Decline from (0,h) to (10,0)
See attachment for graph
Required
Determine the age when height = 0
The function of the graph is represented as: (age, height)
So, we need to read from the graph the corresponding value of age (on the x-axis) when height = 0 (i.e. the y-axis)
From the attached graph;
[tex]age = 10[/tex] when [tex]height = 0[/tex]
Hence, the age of the car is 10 years

Four members of a relay team evenly split the distance of a race. Each person ran more than 100 meters. Which inequality can be used to represent d, the total distance the group ran?
4 d greater-than 100
4 d less-than 100
StartFraction d Over 4 EndFraction greater-than 100
StartFraction d Over 4 less-than 100
Answers
Answer:
The answer would be C.
Step-by-step explanation:
Since each person ran more than 100 meters, the answer would be greater than 100.
d is the total distance the group ran, not the individual distance, so it couldn't be 4d because that would mean it would be 4 times d.
The answer would be d divided by 4. d/4. That is because the total distance divided by 4 would be the individual distance.
Answer:
it is c

On a coordinate plane, parallelogram H I J K is shown. Point H is at (negative 2, 2), point I is at (4, 3), point J is at (4, negative 2), and point K is at (negative 2, negative 3).
HIJK is a parallelogram because the midpoint of both diagonals is __________, which means the diagonals bisect each other.
(1,−1)
(1,1)
(1,0)
(0,1)
Answers
Answer:
(1,0)
Step-by-step explanation:
Given
[tex]H = (-2,2)[/tex]
[tex]I = (4,3)[/tex]
[tex]J = (4,-2)[/tex]
[tex]K = (-2,-3)[/tex]
Required
The midpoint of the diagonals
Midpoint is calculated as:
[tex]M = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
For H and J, the midpoint is:
[tex]M = (\frac{-2+4}{2},\frac{2-2}{2})[/tex]
[tex]M = (\frac{2}{2},\frac{0}{2})[/tex]
[tex]M = (1,0)[/tex]
For I and K, the midpoint is:
[tex]M = (\frac{4 - 2}{2},\frac{3-3}{2})[/tex]
[tex]M = (\frac{2}{2},\frac{0}{2})[/tex]
[tex]M = (1,0)[/tex]
