The proof of the value of the inverse equation f^-1(50) = 3 is below

From 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

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.

Answer:

The area of the red carpet is 1057 ft²

Step-by-step explanation:

The area of the red carpet is 112.35 ft².

Given that, the width of the stage =63 ft and the length of the stage =10 2/3 ft.

The area of a rectangle is obtained by multiplying its length and width. Thus, the formula for the area, 'A' of a rectangle whose length and width are 'l' and 'w' respectively is the product "l × w".

Now, the width of the red carpet is 1/6 of the width of the floor = (1/6) × 63

=10.5 ft

Here, 10 2/3 can be written as 10.66 ≈ 10.7 ft

The area of the red carpet = length × width = 10.7 × 10.5

=112.35 ft²

Therefore, the area of the red carpet is 112.35 ft².

Answer:

x is 60 because the total of angles in a triangle is 180 degrees

Answer: 5

Step-by-step explanation:

Since we are given two angles and one side, we can use the side angle side comparison logic to figure out that all sides are 7 and all angles are 60. Since we are given that a side with length 7 is also 2x-3, we can infer that 2x-3=7. 2x=10, x=5. easy

Answer:

399 minutes a month

Step-by-step explanation:

As I understand the question the answer would, in other words, be how many minutes you can long-distance call with the economy plan for under $30.

The unit ratio is 5 cents per minute, which equates to 20 minutes worth of call time for one dollar (100/5).

The economy plan is $20 cheaper than the deluxe plan. $20 spent on long-distance calling gets you 400 mintues, but the question asks for an integer that would still leave remaining money.

Therefore the answer is 399 minutes of long-distance calling, which would leave five unspent cents.

Answer → x = 96° (degree)

Answer:

96 Degrees

Step-by-step explanation:

If we look at the problem, we know that due to the fact that they are adjacent that they MUST be equal.

Here is the proof:

We'll assign each angle a letter as following

A B C D with A being the top left and D being the bottom right!

Now that we know that, first off, A has to be equal to 180-96 due to them being Supplementary Angles.

Therefore, A is 84 degrees.

Now to find x, we can use Supplementary Angles again.

x has to be 180-84 which is 96 degrees proving the theorum.

Have a nice day!
