Step-by-step explanation:
The value of the exponential equation is y = 3ˣ and the graph is plotted
What are the laws of exponents?When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
y = 3ˣ be equation (1)
Now , the y intercept of the equation is when x = 0
So , when x = 0
y = 3⁰
y = 1
Now , when y₁ = 3^1.2
The value of y₁ = 3.7
Therefore , the y intercept of the equation is 1 and the graph is plotted
Hence , the exponential equation is y = 3ˣ

A and B start toward each other at the same time from points 150 miles apart.
If A went at the rate of 20 miles an hour, at what rate must B travel if they
meet in 5 hours?
Answers
Answer:
B must travel at the rate of 10 miles per hour.
The speed at which B should travel is 10 mph
What is Speed?
Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the distance between A and B be D = 150 miles
Now , the equation will be
The speed of A = 20 mph
Let the speed of B be = B
The time required T = 5 hours
From the equation , Distance = Speed x Time
Substituting the values in the equation , we get
150 = ( A x T ) + ( B x T )
20 x 5 + ( B x 5 ) = 150
On simplifying the equation , we get
100 + 5B = 150
Subtracting 50 on both sides of the equation , we get
5B = 50
Divide by 5 on both sides of the equation , we get
B = 10 mph
Therefore , the value of B is 10 mph
Hence , the speed of B is 10 mph

Carlos can run 5 miles in 45 minutes, Kelly can run 10 miles in 80 minutes, and Mick can run 30 miles in 170 minutes
Answers
Answer:
Mick can run farther in less time if that's the question
Step-by-step explanation:
Mick's speed is faster.
What is speed?Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
We have,
Carlos can run 5 miles in 45 minutes.
45 minutes = 45/60 = 0.75 hours
Speed.
= 5/0.75
= 6.66 miles per hour.
Kelly can run 10 miles in 80 minutes.
80 minutes = 1.33 hours
Speed.
= 10/1.33
= 7.5 miles per hour.
Mick can run 30 miles in 170 minutes
170 minutes = 2.8 hours
Speed.
= 30/2.8
= 10.7 miles per hour
Thus,
Mick's speed is faster.
