If the function f(x) = 5(2x) is squared, which function is produced?
The function is a linear function, and the equation of the function when squared is (f(x))² =25(4x²)
How to determine the new function?The equation of the function is given as:
f(x) = 5(2x)
When the function is squared, we have:
(f(x))² =(5(2x))²
Evaluate the exponent
(f(x))² =25(4x²)
Hence, the equation of the function when squared is (f(x))² =25(4x²)

Answer:
This method is incorrect.
Step-by-step explanation:
The student's understanding of an exponent -1 is correct, but applying it to the inverse function f^-1(x), is wrong.
The method to find inverse function is to replace f(x) with y, switch x and y, then solve for y.
To use the (incorrect) "simple method" Put a 1 on top and move the function to the bottom (denominator).
For example, let's look at the function f(x) = x+3
Write y in place of f(x).
y = x + 3
Switch x and y.
x = y + 3
Solve for y.
Subtract 3.
x - 3 = y
Rewrite.
y = x - 3
This is the proper inverse function.
f^-1 (x) = x - 3
Using the (incorrect) "simple method"
f(x) = x + 3
f^-1(x) = 1/(x+3)
This shows that the shortcut doesnot work, its wrong. To do it correctly, switch x and y and solve for y.

Check photo for work
The 12 pounds of ground beef cost is $15.48.
What is unitary method ?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the question
8 pounds of ground beef cost $10.32
i.e 8 pounds of ground beef = $10.32
1 pounds of ground beef = [tex]\frac{10.32}{8}[/tex]
1 pounds of ground beef = $1.29
Therefore,
12 pounds of ground beef = 1.29*12
12 pounds of ground beef = $15.48
Hence, 12 pounds of ground beef is of $15.48.

Amy and Julie are going camping.
Each of them both has a bag of marshmallows. The bag of marshmallows has 30 marshmallows inside. The girls also bring crackers. If Amy and Julie make 15 s'mores, how many crackers and marshmallows did they use?
Answer:
60 marshmallows and 30 crackers
Step-by-step explanation:
Each girl brought a bag of marshmallows containing 30 marshmallows inside. 2 x 30 = 60 marshmallows altogether.
Since there are 15 s'mores, we have to distribute the marshmallows equally.
60 ÷ 15 = 4 marshmallows in each. But if we multiply that again ( 15 x 4 ) we get 60 again. Thus, they used 60 marshmallows altogether.
The girls make 15 smores. A s'more has two crackers inside one.
2 x 15 = 30 crackers.
Hope this helped.
Answer:
60 marshmallows and 30 crackers
explanation:
1. 15 x 4 = 60
60 divided by 15 = 4
2. 15 x 2 = 30

28.26 x 9/3
28.26 x 3
answer = 84.78
Answer:
84.78 inches cubed
Step-by-step explanation:
You need to comprehend the volume formula for cones
Volume Formula for Cones: V=1/3hπr²
Your measurements:
9 inches for height
3 inches for radius
**Radius is half of a circle and diameter is full of the circle/base.***
Equation:V=1/3 x 9in x π x 3²
You should do 3 squared first so that you can input it into your calculator easily.
V=1/3 x 9in x π x 9
Now on a calculator do 1 divided by 3 which is the "1/3" in the formula.
Then multiply 9, 3.14 for pi, and 9 for radius.
Note: You should do 3.14 for pi not the whole pi symbol on the calculator.
Your answer: 84.78 in cubed

3.75 * 3 * 5 =
231 - 7a = 98
How to solve this
Answer:
19
Step-by-step explanation:
231 - 7a = 98 = -7a + 231 = 98
Subtract 231 from both sides to get -7a = -133
Divide by -7 on both sides to get a = 19
Answer:
a = 19 is the correct solution.
Step-by-step explanation:
Step 1 : Start by simplifying both sides of the problem.
231 − 7a = 98
231 + − 7a = 98
−7a + 231 = 98
Step 2 : Next step is to subtract 231 from both sides
−7a + 231 − 231 = 98 − 231
−7a = −133
Step 3: Finally, divide both sides by -7.
( When I use the symbol /, it signifies I'm dividing.)
-7a/-7 = -133/-7
-133 divided by -7 equals 19
This shows that a = 19. I hope this helps! :D

It takes staff members 162 minutes total each night to clean all six ovens. If each staff
member works for 18 minutes, how many staff members does it take to clean the
ovens?
Answer:
9
Step-by-step explanation:
If it takes 162 minutes each night to clean all 6 ovens, and each staff member works for 18 minutes each then we have to use division to find out how many staff members it will take to clean the ovens.
First we have to divide 162 by 18 which equals 9. This is a one step problem, so 9 is the answer.
It will take 9 staff members to clean all 6 ovens.
Happy Holidays
It takes 9 staff members to clean all six ovens, with each staff member working for 18 minutes.
Given that total cleaning time is 162 minutes
Time per staff member is 18 minutes
To find the number of staff members (N), we divide the total cleaning time by the time per staff member:
N = Total cleaning time / Time per staff member
N = 162 minutes / 18 minutes
N = 9
Therefore, it takes 9 staff members to clean all six ovens, with each staff member working for 18 minutes.
