Answer:
y=x^2-2
Step-by-step explanation:
It should be this one because if you have x squared it will be a parabola. A line should have a consistent slope. so Somethingx + y intercept =y
Answer:
5mph
Step-by-step explanation:
Given that two cars are 40 miles apart at the beginning.
They started at the same time with speeds 48 mph and 56 mph respectively
Since both cars are travelling in the same direction,
Relative velocity = Speed of the behind car-Speed of the first car
=56-48 =8mph
To catch the I car, the second car has to travel a distance of 40 miles extra in the same time as the I car
i.e. speed to be made up by the second car = 40 miles
Relative velocity per hour = 8mph
Hence time taken to catch up = 
Answer:
<h3>7x+3y+4</h3>
Step-by-step explanation:
The rate of the faster car would be 87 kilometers per hour.
<em>200.96 cm^3</em>
Step-by-step explanation:
The equation for the volume of a cone is...

Since we are using 4 for the radius we can plug that in, along with 12 for the height and 3.14 for pi.
So the equation with everything plugged in will be...

Now we can solve.

The volume of the cone is...
<em><u>200.96 cm^3</u></em>
