Answer:
82,068.55 = f(66)
Step-by-step explanation:
Here you want to "evaluate" the function "f" at x = 66.
We have f(66) = 1.1e^(11.22) = 1.1(74607.78) = 82,068.55 = f(66)

Answer:
Part a) The average speed is 
Part b) The linear equation that represent the situation is
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
x ----> the time in hours
y ---> the distance biked in miles
we have the points
(0,0) and (4.5,63)
This problem represent a proportional relationship because is a line that passes through the origin
Find the constant of proportionality k

For the point (4.5,63)

The constant of proportionality or slope represent the average biking speed in miles per hour
so

The equation is equal to
Answer:
y = mx + 1/2
Step-by-step explanation:
(x,y)
- Plot each point on a graph
- The line should go from the bottom left (-6,-10) to the top right (1,4)
- Count how many spaces are on the y-axis from -6 to 1 for numerator
- Count how many spaces are on the x-axis from -10 to 4 for denominator
- Positive slope
- Slope = 7/14
- Simplify to 1/2
Answer:
Inital height is 20
Step-by-step explanation:
h= (-5x-5)(x-4)
h= -5x^2+15x+20
