The graph of f(x) is shown below.
(First image below)
If g(x) and f(x) are inverse functions, which graph represents g(x)?
A. 2nd Graph below
B. 3rd Graph below
C. 4th Graph below
D. 5th Graph below
Answers
[tex]f(x) = \sqrt{x} [/tex]
to find the inverse, replace f(x) with y, switch the x and the y, then solve for y
[tex]f(x) = \sqrt{x} ... \: y = \sqrt{x} \\ x = \sqrt{y} \\ {( \sqrt{y})}^{2} = {x}^{2} \\ y = g(x) = {x}^{2} [/tex]
The only graph showing exponential growth is the 2nd graph (note how at 1 it's 1, at 2 it's 4, at 3 it will be 9, etc.)
Given that we have the graph of f(x), we want to see which one is the graph of its inverse. The correct option is B, the third graph.
Remember that two functions f(x) and g(x) are inverses if:
f(g(x)) = g(f(x)) = x
This also means that if:
f(x) = y
then g(y) = x.
So we basically should have the exact same graph of f(x), but we just "interchange" the two axes.
From this, we can see that the correct option is the third graph (the one where the curve goes upwards. So the correct option is B.

A rational number between 9.6 and 9.7 is 93/20.
The given decimal numbers are 9.6 and 9.7.
What are the rational numbers?Rational numbers are in the form of p/q, where p and q can be any integer and q ≠ 0. This means that rational numbers include natural numbers, whole numbers, integers, fractions of integers, and decimals (terminating decimals and recurring decimals).
Now, (9.6+9.7)/2

a furlong is a unit of length still used today in racing and agriculture. a race that is 8 furlongs is 1 mile. a furlong is 660 feet. how many furlongs are in 1 mile?
Answers
There are 0.125 miles in one furlong.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Examples:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
There are 8 furlongs in 1 mile.
Since a furlong is 660 feet, we can convert the number of feet into 1 mile.
Now,
1 mile = 5280 feet
Multiply 660/5280 on both sides.
660/5280 mile = 660 feet
0.125 mile = 660 feet

Dam is rowing a boat away from a dock the graph shows the relationship between the time and sams distance from the dock. Evaluate the function for an input of 9
Answers
A and C would not be correct because you are finding the distance for 9 minutes. D is not correct because the y-axis does not even have 3 meters on it, neither does the graph hit y=3.
Answer:
B. After 9 minutes Sam is 80 meters away from the dock.
Step-by-step explanation:
We have been given a graph of function that shows the relationship between the time and Sam's distance from the dock.
Let us see our given options one by one to find the correct choice.
A. After 80 minutes Sam is 9 meters away from the dock.
Upon looking at our graph we can see that y-axis is representing distance in meters and x-axis is representing time in minutes. Range of x is from 0 to 11 So our input cannot be greater than 11.
Therefore, option A is not a correct choice.
B. After 9 minutes Sam is 80 meters away from the dock.
We can clearly see from our given graph that at 9 minutes distance is 80 meters, which means that after 9 minutes Sam is 80 meters away from the dock. Therefore, option B is the correct choice.
C. After 80 minutes Sam is 80 meters away from the dock.
We can see from our graph that range of x is from 0 to 11 minutes, So our input can not be greater than 11. Therefore, option C is not a correct choice.
D. After 9 minutes Sam is 3 meters away from the dock.
We can see from our graph that initial value of our function is 20, which means that at time equals 0 minutes Sam was 20 meters away from dock and this distance is increasing with the time. Therefore, option D is not a correct choice.

If a train is moving 72 km/h on a road of 360 km, how much time will it take to arrive?
Answers
72 kilometers is 72,000 meters, and an hour is 60 minutes of 60 seconds each, meaning an hour is 3600 seconds (60m*60s). This means that in 3600 seconds the car travels 72,000 meters. You can figure out how many meters are travelled per second by dividing 72,000 meters by 3,600 seconds, giving you 20 meters per second. This would give you an answer of 80 meters in 4 seconds, not 120 m. I don't know how to account for that disparity, but 80 meters would be the correct answer.

I have part A however idk how to work out part B how would i write the equation out???
Answers
We find the slope by choosing two points that are on the line:
(9, 18) is easy to spot; and (2, 7) is fairly easy to spot as well. The formula for slope is:
m=y₂-y₁/x₂-x₁
m=7-18/2-9 = -11/-7 = 11/7
Slope intercept form, y=mx+b, has the slope and the y-intercept. Plugging those in we have y=11/7x+3.
y-yo = m (x-xo)
We look for the slope:
m = (y2-y1) / (x2-x1)
m = (18-15) / (9-7)
m = (3) / (2)
m = 3/2
We write the equation choosing any point:
y-15 = (3/2) (x-7)
we rewrite the equation:
y-15 = (3/2) x-10.5
y = (3/2) x-10.5 + 15
y = (3/2) x + 4.5
Then, for x = 13 we have:
y = (3/2) * (13) +4.5
y = 24
Answer:
The equation is:
y = (3/2) x + 4.5

Compare how you would model and record finding the sum difference of two rocks weighing 2/8 pound and 3/8 pound.
Answers
3/8-2/8=1/8
hope this helped
Final answer:
To find the sum or difference of two rocks weighing 2/8 pound and 3/8 pound, add or subtract their numerators while keeping the denominator the same. The sum is 5/8 pound, and if finding a difference with the second rock being lighter, it's 1/8 pound.
Explanation:
To model the sum of two rocks weighing 2/8 pound and 3/8 pound, we work with fractions with the same denominator. To find the sum, simply add the numerators together and keep the same denominator. Thus, 2/8 + 3/8 equals 5/8. To record the sum difference, you list both weights then show their combined weight, which is the sum.
The process is like this:
Write down the weights of the two rocks: 2/8 pound and 3/8 pound.Add the numerators (2 + 3 = 5) while keeping the denominator the same (8).The sum is therefore 5/8 pound.If we were to find the difference, you would subtract the smaller numerator from the larger numerator:
Assuming we're taking the second rock's weight from the first: 3/8 - 2/8.Subtract the numerators (3 - 2 = 1) while keeping the denominator the same (8).The difference is therefore 1/8 pound.
