One of the zeroes would be : x = 1
f (1) = 1^3 + 6(1) ^2 + 3 (1) - 10
f(1) = 1 + 6 + 3 - 10
f (1) = 10 - 10
f (1) = 0
Hope this helps
Answer:
The total cost is $81.78
Step-by-step explanation:
First lets calculate the tip
tip = cost * percent of tip
tip = 65.42*.25
tip = 16.355
Which rounds to 16.36 since we are working with money and round to the nearest cent
total cost = cost of cut and blowout + tip
= 65.42 +16.36
=81.78
The return trip was 21.2 hours long.
Step-by-step explanation:
Given,
Speed of plane from US = 212 mph
Speed of plane on return trip = 232 mph
Let,
x be the time taken on return trip.
Time taken from US = x+2
We know that;
Distance = Speed * Time
Distance of plane from US = 212(x+2) = 212x+424
Distance on return trip = 232x
As the distance will be same, therefore,

Dividing both sides by 20

The return trip was 21.2 hours long.
