Answer:
(1, -1)
Step-by-step explanation:
You have the point ...
(3, f(3)) = (3, -1)
The corresponding point on the horizontally compressed graph will be ...
(3x, f(3x)) = (3, -1)
(x, f(3x)) = (1, -1) . . . . . the first coordinate of the given point is divided by 3
The time of takeoff of this hovercraft would be 0 seconds, as if you were starting a timer. So, if you plug in 0 for x (unit for seconds) in your equation, it will look like this:
h(0) = -3(0 - 3)² + 108
Parenthesis first
h(0) = -3(-3)² + 108
Exponents next
h(0) = -3(9) + 108
Multiplication
h(0) = -27 + 108
Combine like terms
h(0) = 81: The height of the hovercraft at the time of takeoff is 81 meters!
Hope this helps :)
A conversion factor is used to change the units of a measured quantity without changing its value. Because of the identity property of multiplication, the value of a number will not change as long as it is multiplied by one.
Answer:
Statistic
Step-by-step explanation:
Generally, when we talk about statistic, we are talking about the characteristic of a sample. A statistic can be said to be a value which is calculated or computed from the values in a sample.
By applying mathematical functions in this case addition and division to the values present in the sample, we have what is now known as statistic.
