Answer:
Yes, both have the same value ( 20) when x = 5.
Step-by-step explanation:
We have two functions:
y = 15 + x
y = 4*x
We want to see if these functions have the same value when x = 5.
Then we just need to replace x by 5 in both equations, and see if the values of y are the same
first function:
y = 15 + 5 = 20
second function:
y = 4*5 = 20
So yes, both functions are equal to 20 when x = 5.
Rise over run: (9 - 4)/(-4 + 3)= 5/-1
Divide: 5/-1 = -5
The answer is B.
Answer:
a. 38.19m/s
b. 38.605m/s
c. 38.937m/s
d. 39.0117m/s
e. 39.01917m/s
Step-by-step explanation:
The average velocity is defined as the relationship between the displacement that a body made and the total time it took to perform it. Mathematically is given by the next formula:
Where:
a. Let's find h(3) and h(4) using the data provided by the problem:
The average velocity over the interval [3, 4] is :
b. Let's find h(3.5) using the data provided by the problem:
The average velocity over the interval [3, 3.5] is :
c. Let's find h(3.1) using the data provided by the problem:
The average velocity over the interval [3, 3.1] is :
d. Let's find h(3.01) using the data provided by the problem:
The average velocity over the interval [3, 3.01] is :
e. Let's find h(3.001) using the data provided by the problem:

Answer:
The bus =40 kilometers
The car = 60km
Step-by-step explanation:
step one:
given
The speed of the car was 120 kilometers per hour
The speed of the bus is 40 kilometers per hour slower than the speed of a car
hence the speed of the bus is = 120-40 = 80 kilometers per hour
Required
The distance traveled
we are told that they spent the same amount of time.
let the distance covered by the bus be x kilometers
so the distance covered by the car = (20+x) kilometers
Step two:
from
v=d/t
time= d/v
time taken by the car
= 20+x/120-----------1
time taken by the bus
= x/80--------2
equate both equations
20+x/120=x/80
cross multiply
120x=80(20+x)
120x=1600+80x
120x-80x=1600
40x=1600
divide both sides by 40
x=40 kilometers
The bus travels 40 kilometers
The car travels 20+40= 60km
