Answer: Choice C

[tex]y = x^2+2, \ x \ge 0[/tex]

=============================================

Work Shown:

[tex]f(x) = \sqrt{x-2}\\\\y = \sqrt{x-2}\\\\x = \sqrt{y-2} \ \text{ swap x and y}\\\\x^2 = y-2 \ \text{ square both sides}\\\\y = x^2+2\\\\f^{-1}(x) = x^2+2\\\\[/tex]

Since the range of f(x) is [tex]y \ge 0[/tex] this means the domain of the inverse will be [tex]x \ge 0[/tex]

The domain and range swap when you go from the original function to the inverse, or vice versa (due to x and y swapping)

So we must state the inverse is [tex]y = x^2+2 , \ x \ge 0[/tex]

Answer:

Following are the solution to the given points:

Step-by-step explanation:

In point a:

The middle point of the segment AB will be the hypothesis, which is equal to M.

In point b:

The conclusion of AB = 2AM.  

In point c:

If p q is incorrect, after all, M is not really the middle point of a section AB, then the inference is wrong.

Answer:

c

Jamal

Step-by-step explanation:

The statements are

[tex]-0.5[/tex] and [tex]-\dfrac{1}{2}=0.5[/tex]

They are equivalent

[tex]0.\bar{7}=0.7777\dots[/tex] and [tex]\dfrac{7}{10}=0.7[/tex]

They are not equivalent.

[tex]\dfrac{11}{20}=0.55[/tex] and [tex]0.55[/tex]

They are equivalent.

[tex]\dfrac{-1}{50}=-0.02[/tex] and [tex]-0.02[/tex]

They are equivalent

[tex]0.15[/tex] and [tex]0.1\bar{5}=0.15555\dots[/tex]

They are not equivalent.

Jamal's record [tex]\dfrac{7}{9}=0.\bar{7}[/tex]

Brian's record [tex]\dfrac{5}{8}=0.625[/tex]

[tex]0.\bar{7}>0.625[/tex]

So, Jamal's record is better.

Answer: It $7.80 per hour

Hi hi

Step-by-step explanation:

In order to solve how many problems each person has solved, you have to multiply the fraction by the number of problems on their assignment. To do this, you multiply the numberator by the number of problems and then divide that by the denominator for both Dustin and Kelsey.

For Dustin, 3/8 * 24 = 72 / 8 = 9 problems completed

For Kelsey, 4/15 * 30 = 120/15 = 8 problems completed

Dustin has completed more problems

Answer:9

Step-by-step explanation:

Dustin done more he done 9 and kelsey done 8

Answer:

p= 18,275

Step-by-step explanation:

The function would be p=29,175(-0.925)^t. You would then substitute t for 6 and solve from there to get p=18,275.

Answer:51.14

Step-by-step explanation:since its an isosceles triangle all interior angles are gonna be equal the exterior angle plus interior angle is will be kept equal to 360

2x+5+5x-3=360

7x+2=360

7x=358

x=51.14

The measure of each angle is 31, 31 and vertex angle is 118.

If a triangle side is created, the outside angle that results is equal to the product of the two opposite internal angles.

Given:

Base angle = (2x+ 5) and Vertex = (5x- 3)

So, We know that the exterior angle is equal to sum of opposite interior angle

5x- 3 = 2x+ 5 + 2x + 5

5x - 3= 4x + 10

x= 13

Thus, Each angle measure 2(13)+ 5 = 31 and

third angle = 180 - (5x- 3) = 180- 62 = 118

Hence, the measure of each angle is 31, 31 and vertex angle is 118.

320 is 80% of 400

Answer:

A and C

Step-by-step explanation:

Answer:

150%

Step-by-step explanation:

this is because you can make a part to whole ratio where you have x/100 (which would symbolize the percent) and 160/40 (which would symbolize the part) then, multiply 160 by 100 to get 16000 and then divide by 40 to fulfill the x. Hope this helps!

Step-by-step explanation:

Step 1: Define equation

5x + 2 = 20

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 20 does indeed equal 20.

∴ x = 18/5 is a solution to the equation.
