Ascientist invents a car that can travel for many hours without stopping for fuel. the car travels around a track at 51 miles an hour for 24 hours. at the end of the 24 hours, how far has the car traveled? a) 306 miles b) 1,020 miles c) 75 miles d) 1,224 miles

1224 miles

Step-by-step explanation:

Given : The car travels around a track at 51 miles an hour for 24 hours.

To Find: At the end of the 24 hours, how far has the car traveled?

Solution:

Speed of the car = 51 miles/hr

Time taken by car = 24 hours

Now we are supposed to find how far has the car traveled i.e. Total distance

So, Total distance = 1224 miles

Hence The car has traveled 1224 miles

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
