Answer:
[-3,9]
Step-by-step explanation:
you look at the x axis
I believe that the answer you're looking for is B. h+(h+2.5)=22.
h+(h+2.5)=22
h+h+2.5=22
Combine like terms.
2h+2.5=22
Subtract 2.5 from both sides.
2h=19.5
Divide both sides by 2.
h=9.75
Now let's check the work by plugging 9.75 into the equation.
9.75+(9.75+2.5)=22
9.75+9.75+2.5=22
22=22
So we now see that the answer choice <u>B.</u> Is correct! And William worked 9.75 hours. I hope that you found this helpful!
Answer: =9k−26
Step-by-step explanation:
Answer: 
Step-by-step explanation:
Given: The number of bacteria, B, in a refrigerated food is given by the function
, where t is the temperature of food in degrees Fahrenheit.
The function
gives the temperature, t, of the food h hours after being removed from the refrigerator.
Now, the number bacteria in the food in h hours is given by:-

So, The number bacteria in the food in h hours is given by:

The correct answer would be 22.9^2 mm.
Since area of a circle is 'A = piR^2'.
We don't have the radius (from the middle out) but we do have the diameter (from one point to the other). We can divide this by 2 to find the radius.
5.4/2 = 2.7.
The radius is 2.7.
A = 3.14(2.7^2)
A = 22.8
