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.

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.

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.

Step-by-step explanation:

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.

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.

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.
