Answer:
Take a look at the 'proof' below
Step-by-step explanation:
The graph of the function g(x) is similar to that of the function f(t). The local minimum, local maximum, absolute minimum, maximum etc... of 'x' is always the closest x-intercept of the graph of f(t).
Let's check if this statement is right. The two local minimum(s) of the function f(t) occurs at x = 2, and x = 6. The two local maximum(s) occur at 1/4 and 4. As you can see the maximum / minimum of the function g(x) is always an x-intercept, x = 3, x = 7.
For part (b) the absolute maximum value of the function f(t), is 8. The closest x-intercept is 9, which is our solution.
The required temperature at the height of 1200 meters is 13 degree Celcius.
Given that,
Temperature drops an average of 1 degree celsius for every 100 meters that a hot air balloon rises.
The temperature is 25 degrees celsius on the ground.
The approximate temperature is 1200 meters above the ground is to be determined.
<h3>What are functions?</h3>
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
The expression of for temperature drops an average of 1-degree celsius for every 100 meters that a hot air balloon rises.
Let x be the height in meters and y be the temperature in degrees celcius
y = -x/100 + 25
For temperature 1200 meters above ground
x = 1200
y = -1200/100 + 25
y = -12 + 25
y = 13
Thus, the required temperature at the height of 1200 meters is 13 degrees Celcius.

Answer:
Jenna spent 7 hours babysitting.
Step-by-step explanation:
With the information provided, you can say that Jenna's total earnings are equal to the amount she earned cleaning her neighbor's basement plus the result of multiplying the charge per hour for babysitting for the number f hours, which is:
e=20+5x, where:
e represents the total earnings
x is the number of hours
Now, you can replace e with 55 that is the toal amount she earned and solve for x:
55=20+5x
55-20=5x
35=5x
x=35/5
x=7
According to this, the answer is that Jenna spent 7 hours babysitting.
