Answer:
t(h)= (h-200)/-4.9
The time to reach a height of 50 meters is 30.6 seconds
Step-by-step explanation:
To express t as a function of height (h) we must transform the equation below:
h=200-4.9t
h-200=-4.9t
(h-200)/-4.9=t
t(h)= (h-200)/-4.9
To find the time to reach a height of 50 meters, we must replace this value on the new equation:
t(h)=50-200/-4.9
t(h)= 30.612
The time to reach a height of 50 meters is 30.6 seconds
Answer:
True.
Step-by-step explanation:
If I = prt, They are all being multiplied together, therefor being constant.
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:

13:
It is a function, notice that if you draw a vertical line anywhere, it doesn't pass two points.
Domain : All real numbers (x-values)
Range : 2 (y-values)
14:
Not a function, if you draw a vertical line through one point, it will hit two others.
Domain : -3
Range : 4 , 0, -4
15:
It is a function, no two points in any vertical line.
Domain: All real numbers
Range: All real numbers
16:
Not a function, two points in one line
Domain : -5 ≤ x ≤ 5
