Given that f(x) = 3x + 2 and h(x) = x3, find (h o f)(2).
Answer/Step-by-step explanation:
This is what we know...
f(x) = 3x + 2 and h(x) = 3x and that h(2) or x=2
Given that info we can input our values into the variables.
f(2) = 3(2) + 2
Now according to the Order of Operations, we should multiply next.
f(2) = 6 + 2
Now according to the Order of Operations, we should add.
f(2) = 8
I don't know if your question wants it as a ordered pair or not so ignore this if there is any of those. The answer in an ordered pair would be (2,8)
Now we have to do the other equation.
Input our values into the variables
h(2) = 3(2)
Now according to the Order of Operations, we should multiply next.
h(2) = 6
I don't know if your question wants it as a ordered pair or not so ignore this if there is any of those. The answer in an ordered pair would be (2,6)
Hope this Helps! :)

A robot can complete 5 tasks in 3/4
hour. Each task takes the same amount of time.
a. How long does it take the robot to complete one task?
b. How many tasks can the robot complete in one hour?
Answer:
[A] 9 minutes to complete one task
[B] 6 tasks completed, with 2/3rds of another task completed.
Step-by-step explanation:
5 tasks in 45 mins is equal to one task in 9 minutes
60 minutes in an hour, 9 minutes per task = 6 tasks completed, with 2/3rds of another task completed.

Step-by-step explanation:
sin(x)==cos(90-x)
cos(90-195)
cos(-105)
cos(105)
cos(105)= [tex]\frac{\sqrt{2}-\sqrt{6} }{4}[/tex]
Sandra brings 6 dolls to her grandma's house. These dolls represent 60% of her collection, as shown in the diagram. What is the total number of dolls in Sandra's collection.
Answer:
10
Step-by-step explanation:
60% of 10 is 6, so if 6 is 60% then 100% of them would be 10
If 4 gal of premium unleaded gasoline costs $15.04, how much would it cost to completely fill a tank whose capacity is 9-gal?
The cost to completely fill the tank is $
Answer:
$33.84 cents
Step-by-step explanation:
Given the following question:
4 gallons = 15.04
1 gallon = ?
How much for 9 gallons?
To find the answer we have to find how much one-gallon costs since we already know how much it costs for 4 gallons of this unleaded gasoline.
[tex]15.04\div4[/tex]
[tex]15.04\div4=3.76[/tex]
[tex]=3.76[/tex]
One gallon of this gasoline costs $3.76 now we need to find how much it costs for 9 gallons.
[tex]3.76\times9=33.84[/tex]
[tex]=33.84[/tex]
For nine gallons of gasoline it will cost you "$33.84 cents."
Hope this helps.
Find the equation of the line that is parallel to the line y = 3x + 1 and passes through
the point (1, 2).
(Show Work and steps)
Answer:
[tex]y=3x-1[/tex]
Step-by-step explanation:
lines that are parallel have the same gradient
using this fact we can create the equation:
[tex]y=3x+c[/tex]
and substitute in our values
[tex]2=3+c[/tex]
[tex]c=-1[/tex]
so the equation of the line is [tex]y=3x-1[/tex]

A motorboat takes 3 hours to travel 108 kilometers going upstream. The return trip takes 2 hours going
downstream. What is the rate of the boat in still water and what is the rate of the current?
Answer:
45 km/h and 9 km/hStep-by-step explanation:
Let the rate of boat in still water be b and the speed of the current be c
Speed downstream = b + cSpeed upstream = b - cWe got equations for time:
108/(b - c) = 3 ⇒ b - c = 36108/(b + c) = 2 ⇒ b + c = 54Add up the equations:
b - c + b + c = 36 + 542b = 90b = 45 km/hThen finding the values of c
c = 45 - 36 = 9 km/hPlease help me find the missing angle measures. :(

An airplane on autopilot took 5 hours to travel 3,475 kilometers. What is the unit rate for kilometers per hour?
A car manufacturer claims that the company’s newest model has a peak power of exactly 329 horsepower. Katherine is a reporter for an automotive magazine. She is testing the manufacturer's claim and says that the population mean peak power is less than the advertised amount. She measures the peak horsepower of 42 randomly selected cars of the new model. The sample mean is 327.74 horsepower with a standard deviation of 2.41 horsepower. Should Katherine reject or fail to reject the null hypothesis given the sample data below? H0:μ=329 versus Ha:μ<329 α=0.05 (significance level) t≈−3.39 with 41 degrees of freedom p-value<0.005
Answer: Katherine should reject the null hypothesis.
Step-by-step explanation:
We reject the null hypothesis when p-value is less than the significance level.
here, H0:μ=329 versus Ha:μ<329
α=0.05 (significance level)
p-value<0.005
so , we should reject the null hypothesis as p-value is less than the significance level.
Hence, Katherine should reject the null hypothesis.

In all, 54 children were assigned to the Montessori school and 115 to other schools at age three. When the children were five, parents of 38 of the Montessori children and 34 of the others could be located and agreed to and subsequently participated in testing. This information reveals a possible source of bias in the comparison of outcomes. Explain why. (Round your answers to the nearest whole number.) About % of Montessori parents participated in the study, compared to about % of the other parents. (c) One of the many response variables was score on a test of ability to apply basic mathematics to solve problems. Here are summaries for the children who took this test:
Full question attached
Answer:
Option C: because the percent of children compared differ too much
Explanation:
Sample Proportion of students from Montessori = students that participated from Montessori /total number of students assigned to Montessori
=30/54= 0.56
Sample proportion of students from other schools = students that participated I'm the study /total number of students assigned to other schools
=25/112
=0.22
We observe that there is a large difference(0.56-0.22) between the two sample proportions hence the bias

For each part, first decide which of the three methods sections will most easily enable you to sketch the surface. These are the generalized cylinder method, the surface of revolution method, and the method of slices (traces) for general quadric surfaces. Then apply that method to sketch the surface.
a. x^2 = 4z +8
b. x^2 - 4y^2 – 4z^2 = 16
c. y^2 = x^2 + 2z^2
Answer:
Step-by-step explanation:
We use these three methods
1. Generalized cylinder method
2. Surface of revolution method
3. Method of slices general quadratic
1. For A = x² = 4z + 8
We use the method of slices for general quadratic
2. X²-4y²-4z² = 16
We use the generalized cylinder method
3. Y² = z² + 2z²
We use surface of revolution

Answer:
41
Step-by-step explanation:
Answer:
the value of x is 41°
Step-by-step explanation:
x + 76°+63° = 180°{being straight angle}
or, x+139° = 180°
or, x = 180° - 139°
or, x = 41°

The Pythagorean theorem states that a² + b² = c² for a right triangle with leg lengths, a and b, and hypotenuse length, c.
The hypotenuse of a right triangle is 5 units long and has the points (3, 0) and (0, 4) as end points. One of the legs has length 3.
Use the Point and Segment tools to draw a right triangle at demonstrates the other leg length is 4.
Answer:
Step-by-step explanation:
Draw the third point at (0, 0). This would make the distance from (3,0) to (0,0) equal to 3, and the distance from (0,4) to (0,0) be 4.
