Answers
Answer:
Step-by-step explanation:
12) f(x) = 3x
y = 3x
x = 3y
x/3 = y
13) f(x) = 4x-10
y = 4x - 10
x = 4y - 10 (isolate y)
(x+10)/4 = y
The required inverse function would be f⁻¹(x) = x / 3.
What is an inverse function?The inverse function is defined as a function obtained by reversing the given function.
To determine the inverse of a function, all you have to do is switch where x and y are and resolve for y.
We have to find the inverse of the function below :
f(x) = 3x
So after switching x and y,
Now, we solve for y regularly.
f(x) = x = 3y
Solve for y :
⇒ x = 3y
⇒ x / 3 = y
⇒ y = x / 3 = f⁻¹(x)
Therefore, the required inverse function would be f⁻¹(x) = x / 3.

Answer:
x = 9.47 degrees ( in first quadrant.
Step-by-step explanation:
sin2x + sinx cos x = 1/2
Now sinx cos x = 1/2sin2x so:
3/2sin2x = 1/2
sin2x = 1/2 / 3/2
sin2x = 1/2 * 2/3 = 1/3
2x = arcsin 1/3 = 19.47 degrees
x = 9.74 degrees to nearest hundredth.

What is the smallest multiple of 18 of the form 2A945B, where A and B are digits?
Answers
Answer:
[tex]219456[/tex]
Step-by-step explanation:
It must end in [tex]0,2,4,6,8[/tex] (divisible by 2 rule) and the digits must sum to a multiple of 9(divisible by 9 rule).
The digit sum is [tex]2+A+9+4+5+B=20+A+B[/tex].
We want to make [tex]A[/tex] as low as possible because it's a higher digit than [tex]B[/tex].
If [tex]A[/tex] is as low as possible, we have that the sum is [tex]20+0+7=27[/tex]. Uh-oh. [tex]B[/tex] has to be even! So [tex]A=0[/tex] doesn't work.
If [tex]A=1[/tex], we have that the sum is [tex]20+1+6=27[/tex]. Yay!
So, the answer is [tex]\boxed{219456}[/tex]

suppose another line for a chair lift is placed at a constant distance c below the gondola line. what is the equation of the new line? is the new line also parallel to the hill? explain.
Answers
Answer:
Yes They are Parallel.
Step-by-step explanation:
The required equation of the line y = ax + c as of the old line and also the line is parallel to the hill.
Given that,
Suppose another line for a chair lift is placed at a constant distance c below the gondola line. the equation of the new line and is the line parallel to the hill is to be discussed.
A line is a straight curve connecting two points or more showing the shortest distance between the initial and final points.
Here,
The required new line is placed at a constant distance c below the gondola line,
If the line has a constant distance from the other line that implies that the line is parallel, and the equation of the line is given as,
y = ax + c
Thus, the required equation of the line y = ax + c as of the old line and also the line is parallel to the hill.

First Class Airlines has 40 pilots for every 15 aircrafts. If they employ 250 pilots, how many aircrafts does First Class Airlines own?
(Answer is ratio or proportion)
Answers
We want to find a proportional relationship between the number of pilots and aircraft, and use that to find the number of aircrafts for a given number of pilots.
We can expect to have 94 aircrafts if there are 250 pilots.
Let's see how to get that.
We start by defining what a proportional relationship is.
A proportional relationship between two variables x and y can be written as:
y = k*x
Where k is the constant of proportionality.
Here we do know that there are 40 pilots for every 15 aircrafts, then we can replace these values in the general proportional equation, where x will be the number of aircrafts and y the number of pilots.
40 = k*15
40/15 = k
Now we know the proportional relationship:
y = (40/15)*x
Now to find the number of aircrafts given that we have 250 pilots, we just need to replace the number of pilots by 250 and solve for x:
250 = (40/15)*x
250*(15/40) = x = 93.75
We can round this to the next whole number, 94.
So we can expect to have 94 aircrafts if there are 250 pilots.
