Answer:240.1 m
Step-by-step explanation:
We are given the following equation that models the the time it takes to an object to fall to the ground:

Where:
is the time it takes to the object to fall to the ground
is the object's initial height
is the acceleration due gravity
Isolating
:



Solving with the given data:

This is the initial height
Answer:
Business A= x
Business B= 2x-2,000,000
Business C= 2(2x-2,000,000)-2,000,000
Step-by-step explanation:
Don't feel like explaining this unless you really want me to. Also, brainliest would really be appreciated.
Answer:
60 miles per hour
Step-by-step explanation:
Use speed = distance / time
Speed = 240 / 4
240 / 4 = 60
Speed = 60
It's a Quadratic that doesn't have any real roots as the parabola doesn't cross the x-axis.
For graphing:
If you're familiar with the parabola of y=x^2, then you could graph that but just translate it upwards by +4 on the y such that f(x)+4 will be equal to it.
If you aren't, then we know the y-intercept is 4, and that's also the point of the minimum point of the curve. If I were you, I'd write a table of some of the integer values:
x y
-2 8
-1 5
0 4
1 5
2 8
The value of y is the same for x and -x as anything squared is positive.This means that there is a line of symmetry in the y-axis.
This then makes it much easier to graph, simply place these points on the graph and make sure the curve is exponential. This means the gradient (steepness) gets greater the bigger the value of x.
If he scored all 2 pointers, it would be 26. If he scored all 3 pointers,it would be 39.
