Find the inverse of f(x)= -4/x-1 +2

Mathematics
1 answer:
Flura [38]3 years ago
8 0

Answer:

The inverse f-1(x) = (2 - x)/4 + 1.

Step-by-step explanation:

Let y = -4 /(x - 1) + 2

-4/(x - 1) = y - 2

x - 1 = (y - 2) / -4

x =  -(y - 2)/4 + 1

x = (2 - y)/ 4 + 1

Now replace x by  f-1(x) ( the inverse) and y by x:

f-1(x) = (2 - x)/4 + 1.

Robert is traveling to Mexico for a family vacation. He is bringing 625 U.S. dollars with him. Robert needs to exchange his mone
Evgesh-ka [11]

Robert should get D. 8281.25 pesos in exchange.

Explanation:

  • Robert is bringing 625 U.S. dollars with him to Mexico. He needs to exchange the money he has with him to Mexico's currency i.e. from U.S. dollars to Mexican pesos.
  • The exchange rate is 13.25 Mexican pesos for each U.S. dollar. So                               1 U.S. dollar = 13.25 Mexican pesos.
  • So to calculate how much 625 U.S. dollars is in pesos we multiply 625 with the exchange rate i.e. 13.25 pesos                                                        625 U.S dollars = 625 × 13.25 = 8281.25 Mexican pesos.

Identify the domain and range of this graph​
RSB [31]

Answer:

domain is [-3,3] & range is [-3,3]

Step-by-step explanation:

When given a graph of a circle and ask to solve range and domain....

First: <u>find the four points</u> of the circle:

(-3,0);(3,0);(0,-3);(0,3) .   <em> **Best to plot these points on this graph to understand where the points are and what we are looking at.</em>

Second: Look for <u>range(vertical directions/left and right) and domain(horizontal direction/up and down)</u>.

domain: x-values, first coordinate  (-3,0) & (3,0)

range: y-values, second coordinate (0,-3);(0,3)

Third: take what you know and solve domain and range*include bracket to show domain and range

domain is [-3,3] & range is [-3,3]

A lighthouse keeper views a small boat at an angle of depression of 62 degrees. The boat is 446 feet away from the base of the l
Genrish500 [490]

Answer: the height of the lighthouse is 838.8 feet

Step-by-step explanation:

The right angle triangle ABC illustrating the scenario is shown in the attached photo.

The angle of depression and angle A are alternate angles, hence, they are the equal.

The height, h of the lighthouse represents the opposite side of the right angle triangle. The distance of the boat from the foot of the lighthouse represents the adjacent side of the right angle triangle.

To determine h, we would apply

the tangent trigonometric ratio.

Tan θ, = opposite side/adjacent side. Therefore,

Tan 62 = h/446

h = 446tan62 = 446 × 1.8807

h = 838.8 feet to the nearest tenth.
