Nikitich [7]

Answer:

Input

Independent variable

Step-by-step explanation:

we know that

<u>Independent variables</u>, are the values that can be changed or controlled in a given model or equation

<u>Dependent variables</u>, are the values that result from the independent variables

we have the function

d(t)=50t

In this problem

This is a proportional relationship between the variables d and t

The function d(t) represent the dependent variable or the output

The variable t represent the independent variable or input

Lillian kicks a football. Its height in feet is given by h(t)= -16t^2+72th(t)=−16t 2 +72t where tt represents the time in second
Hitman42 [59]

The after 9/4 seconds the football is at its highest point which is 81 feet if Lillian kicks a football. Its height in feet is given by h(t)= -16t²+72t

<h3>What is a parabola?</h3>

It is defined as the graph of a quadratic function that has something bowl-shaped.

\rm  h(t)= -16t^2+72t

Making perfect square:

\rm  h(t)= -[(4t)^2-72t+9^2 -9^2]

\rm  h(t)= -[(4t-9)^2 -81]

\rm  h(t)=  81-(4t-9)^2

The highest point will be when term (4t-9)² becomes zero

So the highest point = 81 feet, and it takes:

t = 9/4 seconds

Thus, the after 9/4 seconds the football is at its highest point which is 81 feet if Lillian kicks a football. Its height in feet is given by h(t)= -16t²+72t

Simplify the expression using the laws of exponents. 36x−2y2 15z−3 A) 12x1/2y2 5z3/2 B) 12x2z3 5y2 C) 12y1/2x2z3 5 D) 12y2z3 5x2
tino4ka555 [31]

Answer:

\frac{12 {z}^{ 3} {y}^{2} }{5 {x}^{ 2} }

Step-by-step explanation:

We want to simplify:

\frac{36 {x}^{ - 2} {y}^{2} }{15 {z}^{ - 3} }

The trick is that when a negative index in the numerator comes to the denominator , it becomes positive.

The vice-versa is also true.

That is:

{a}^{ - n}  =  \frac{1}{ {a}^{ n} }

and

{a}^{n}  =  \frac{1}{ {a}^{ - n} }

We simplify to get:

\frac{12 {z}^{ 3} {y}^{2} }{5 {x}^{ 2} }

The last choice is correct.
