How do I find the inverse of the function? Also, is it a function and why?

Mathematics
1 answer:
yaroslaw [1]3 years ago

Answer:

Step-by-step explanation:

Essentially, begin by flipping the x and y terms:

x = (1 - 2y)^2 + 5

Then, solve for y:

\ x = (1-2y)^2 + 5\\\sqrt{x-5} = 1 - 2y\\\sqrt{x-5} - 1 = 2y\\\frac{\sqrt{x-5} - 1}{2} = y^-1\\

Because we know there is only 1 y-value for any given x-value, the inverse of the given function is also a function.

Angle MNO is formed by segments MN and NO on the following coordinate grid:
Eva8 [605]

Answer:

I am 90% sure that the answer is M'N'O' is 90*

Step-by-step explanation:

A line segment MN is shown as M = -1,1 and N= -5,4 this makes a diagonal line across the grid. Another line segment NO is shown with O as ordered pair negative 1, 4. Angle MNO is rotated 90 degrees counterclockwise about the origin to form angle M′N′O′. this is where the angles meet, Rotating the shape (or the angles) does not change the degree of the angle of the shape. I am 99% sure that an 90* angle would be formed. but im just in middle school so what do i know?

The popular candy Skittles comes in five colors. According to the Skittles website, the five colors are evenly distributed in th
Firdavs [7]

Answer:

No, this result is not surprising. It is a little bit more than one standard deviation above 20%

Step-by-step explanation:

Proportion of each color in the population (p) = 0.20

Sample size (n) = 20 Skittles

The standard deviation of a sampling distribution is determined by:

\sigma = \sqrt{\frac{p*(1-p)}{n}}\\\sigma = \sqrt{\frac{0.20*(1-0.20)}{20}}\\ \sigma =0.089

The difference between the observed proportion of 0.30, and the mean proportion of 0.20 is 0.10, which is just a little bit more than one standard deviation of 0.089. Therefore, this result is not surprising since it is a little bit more than one standard deviation above 20%.
