Answer:
52 miles per hour
Step-by-step explanation:
Firstly, It is important to point out that it is Average speed. The Average speed throughout all the way the car traveled.
And this is may calculated by a simple formula or if you'd rather by a proportion. Let's pick this simple formula, what's going to be useful.
Let's do the math!
Average speed = Δs/Δt
Δs = Variation of Space (given in miles) =156 -0
Δt =Variation of Time (given in hours) =3-0
Average Speed = 156-0/3-0 =156/3 =52 miles per hour
It is important to say, Average speed, is a rate so it is given in miles per hour
35km; Since the points on the map are one millionth of their actual size, simply multiply by one million and convert from there.
35*1,000,000 = 35,000,000mm
35,000,000/1000 = 35,000m
35,000/1000 = 35km
Answer:
You add common factors
Step-by-step explanation:
-3x^3 is the only x^3
5x^2 and -6x^2 can be added to get -x^2
4x and 2x can be added to get 6x
-7 and -3 can be added to get -10
the answer is -3x^3-x^2+6x-10
Answer:
The height of the surface increases, then decreases, from the center out to the sides of the road.
Step-by-step explanation:
Let
y------> the height of the surface
x------> the road
we know that
The quadratic regression graphed represent a vertical parabola open downward
The function increase in the interval --------> 
The function decrease in the interval --------> ![(0,5]](https://tex.z-dn.net/?f=%280%2C5%5D)
therefore
The height of the surface increases, then decreases, from the center out to the sides of the road.
400 i think i am pretty sure but if it's wronge i apolize
