Answer:
The expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is 
Step-by-step explanation:
We are given:
Distance = 100 m
Time = 20 s
We need to find:
Speed
The formula used is: 
Putting values and finding the expression

So, the expression that calculates the speed in meters per second of an object that travels a distance of 100 m every 20 s is

Answer:
The answer to your question is 7.8 mi
Step-by-step explanation:
Data
H (4,3)
G (10, 8)
Process
1.- Use the distance between to points formula to find the distance
dHG = 
x1 = 4 y1 = 3
x2 = 10 y2 = 8
2.- Substitution
dHG = 
3.- Simplification
dHG = 
dHG = 
dHG = 
4.- Result
dHG = 7.8 mi
The value of Δy using the function y= 5x^3 as x goes from -2 to 1 is; Δy = 45
The question requests that Δy be computed according to the function, y = 5x³ as x goes -2 to 1.
where:
and
Therefore,
Δy = 45.
