Each Of The Four Graphs Represents A Function. Which Function Has An Inverse That Is Also A Function?840664+-8-6

Answers

Answer 1

Answer124

Step-by-step explanation:

Answer 2

Answer: The answer is C

Step-by-step explanation:  Graph C passes the horizontal line test and becomes a function as the horizontal line does not cut the curve more than once along any line drawn.

Also, the curve passes the vertical line test as well, if a vertical is drawn, it does not cut the curve more than once if drawn any where vertically.

Thus, graph C passes both the horizontal and vertical line test. So the curve has both function and inverse function.

The half-life of Palladium-100 is 4 days. After 24 days a sample of Palladium-100 has been reduced to a mass of 7 mg.

A.) What was the initial mass (in mg) of the sample?


B.) What is the mass (in mg) 4 weeks after the start?

You may enter the exact value or round to 4 decimal places.

Answers

9514 1404 393

Answer:

  A) 448 mg

  B) 3.5 mg

Step-by-step explanation:

24 days is 24/4 = 6 half-lives. That is, the mass of 7 mg is 2^-6 times the initial mass.

A) The initial mass is 2^6×(7 mg) = 448 mg

__

B) 4 weeks is 28 days, or 7 half-lives. The remaining mass will be half the amount after 6 half-lives.

  (7 mg)/2 = 3.5 mg . . . . remaining after 4 weeks

If you jog 8 times around a track that is 600 meters long, how many kilometers have you covered?

Answers

Answer:

0.6 km

Step-by-step explanation:

If If you jog 8 times around a track that is 600 meters long, then 4.8  kilometers you  have covered

What is Unit of Measurement?

A Unit of measure is the actual unit in which the associated values are measured.

Given,

If you jog 8 times around a track that is 600 meters long,

We need to find how many kilometers you have covered.

8 times around a track that is 600

It means we have to multiply eight with six hundred.

8×600

=4800

We know that 1 km is 1000 m

So divide 4800 by 1000 to find in kilometers

4800/1000=4.8km

Hence If you jog 8 times around a track that is 600 meters long, Then 4.8  Kilometers you have covered.

v÷1/6=[tex]\pi[/tex]r³

(when dividing by a fraction, invert and multiply)

6v=[tex]\pi[/tex]r³

6v÷[tex]\pi[/tex]=r³

(6v)/[tex]\pi[/tex]=r³

take the cube root of both sides

A towns population went from 40,000 to 50,000. What was the percent of change in the population?

Answers

Answer:

The percent of change in the population was of 25%.

Step-by-step explanation:

Percent change:

The percent change is given by the change multiplied by 100, and divided by the initial value.

A towns population went from 40,000 to 50,000.

Change: 50000 - 40000 = 10000

Initial value: 40000

10000*100/40000 = 25%

The percent of change in the population was of 25%.

A line passes through the points (4,15) and (9,20). Right in line your function rule in terms of x and y for this line

Answers

Answer:

15

Step-by-step explanation:

use formula y-y1=m(x-x1)

(4,15) = (x1,y1)
(9,20)=(x2,y2)

m is the slope which you don’t have but you can find by doing (y2-y1)/(x2-x1)
m=(20-15)/(9-4)
m=5/5
m=1

y-y1=m(x-x1)
y-15=1(x-4)
y-15=x-4 |+15 to both sides
y=x +11
