The second bus is traveling at a speed of 33.3 miles per hour.

Given that the speed of first bus is 60 miles per hour , distance between both the buses is 700 miles after 8 hour.

We are required to find the speed of second car which is heading towards south.

If first car is travelling at a speed of 60 miles per hour then the distance of first car after 8 hours is 60*8=480 miles.

We have been given that the distance between both the cars after 8 hours is 700 miles,So,

Distance of second car after 8 hours=700-480=220 miles.

We know that the speed is equal to distance divided by time.

We know that we have calculated distance after 8 hours so the speed of second car will be =20/6

=33.3 miles per hour

Hence the speed of second car which is heading towards south is 33.3 miles per hour.

R^2+3r+5-r^3/r is a quadratic/cubic/linear polynomial?
Sergeu [11.5K]

r^2+3r+5-r^3/r is  a linear polynomial

S<u>tep-by-step explanatio</u>n:

based on the highest power of the variables of a polynomial, it can be classified as linear,polynomial, quadratic polynomial,cubic polynomial etc.

In a linear polynomial, the highest power of the variable is 1. The general form of a linear polynomial is ax+b

In a quadratic polynomial, the highest power of the variables is 2.The general form of quadratic polynomial is ax^2+bx+c

In a cubic polynomial,the highest power of variable is 3.The general form of cubic polynomial is ax^3+bx^2+cx+d.

Take the given question and simplify it

r^2+3r+5-r^3/r=r^2+3r+5-r^2\\=3r+5

It is of the form ax+b. Hence it is  a linear polynomial.

draw and label a parallelogram with a base twice as long as the height and an area less than 60 square inches. find the area
liubo4ka [24]
Answer: 5 cm by 10 cm gives an area of 50 cm^2

To do this draw a parallelogram and start by labeling the base as 10 cm. If 10 cm is the base, then the height needs to be 5 cm.

To find the area, multiply the base times height.

This will give you: 5 x 10 = 50 which is less than 60.
