The function f is given by
f(x) = 2x^3– 4
(a) Show that f^-1(50) = 3
Answer:
hope it helps you.....
and I m feeling bad for my handwriting
The proof of the value of the inverse equation f^-1(50) = 3 is below
How to prove the value of the inverse equationFrom the question, we have the following parameters that can be used in our computation:
f(x) = 2x^3 - 4
To show that f^-1(50) = 3, we simply show that
f(3) = 50
substitute the known values in the above equation, so, we have the following representation
f(3) = 2 * 3^3 - 4
Evaluate
f(3) = 50
Hence, the proof of the value of the inverse equation is done

How do you do this, because I really do not know how to do this and plz explain how to do this
Answer:
A
Step-by-step explanation:
the leading degree(the biggest power in the function) x^4 and the leading coefficient is the number next to the highest power which is -5
so the answer should be
-5,4,x -> infinity, f(x) -> -infinity ; x -> -infinity, f(x) -> -infinity
when you get asked questions like this look for the biggest power and the number next to it. if the power is even x will always be positive if its odd x can be either positive or negative it depends on restrictions.
for instance in this example -5 * x^4 will always give you negative because -5 will multiply with a positive number x (the power is even so its always positive)

Sarah took a 20? Test and got 17 problems correct what percent did she get
Answer:
85%
Step-by-step explanation:
Divide the number of problems gotten right by the total number of problems.
Sarah got an 85%.
Use this method.
part/whole = %/100
So.
17/20 = x/100
Cross multiply.
17•100=1700
20•x=20x
Divide by 20
1700÷20=85
Therefore the answer is 85%

1. Optiond D is correct, Triangle proportionality theorem can be used to find a missing length in a right triangle.
2. Option D is correct, the value of x is 6.
1. The Triangle proportionality theorem can be used to find a missing length in a right triangle.
The triangle proportionality theorem states that if a line parallel to one side of a triangle intersects the other two sides at different points, then it divides the remaining two sides proportionally.
2. By triangle proportionality theorem:
NO/OP=NM/x
20/8=15/x
Simplify the LHS:
5/2=16/x
Apply cross multiplication:
5x=15×2
5x=30
x=30/5
x=6
Hence, the value of x is 6.

Determine a series of transformations that would map Figure C onto Figure D.
We have that for the Question, it can be said that The series of transformations that would map Figure C onto Figure D are
[tex]Rotation\ 90\textdegree \ clockwise\\\\Z'=(-2,4),(-2,8),(-5,2,(-8,8)[/tex][tex]Translation\\\\(h,k) \arrow (h*-1,k)\\\\Z'=(2,4),(2,8),(5,2),(8,8)[/tex]
From the question we are told
Determine a series of transformations that would map Figure C onto Figure D.
Generally the Co-ordinates for the Figure C map is is mathematically given as
Z=(-4,-2),(-8-2),(-2-5),(-8-8)
Therefore
Initial Transformation
Rotation 90 \degree clockwise
Hence
Z'=(-2,4),(-2,8),(-5,2,(-8,8)
Final Transformation
Translation
(h,k) \arrow (h*-1,k)
Z'=(2,4),(2,8),(5,2),(8,8)
Therefore
The series of transformations that would map Figure C onto Figure D are
[tex]Rotation\ 90\textdegree \ clockwise\\\\Z'=(-2,4),(-2,8),(-5,2,(-8,8)[/tex][tex]Translation\\\\(h,k) \arrow (h*-1,k)\\\\Z'=(2,4),(2,8),(5,2),(8,8)[/tex]
