Write - x^4+4x^3+5x^3-20x-40 ÷ x^2-5
Word form-
x raised to the power of four plus four x to the power of three plus five x raised to the power of three minus twenty x minus fourty divided by x raised to the power of two minus five
Numerical form-
x^4+4x^3+5x^3-20x-40 ÷ x^2-5
Um... i cant help if there are not any question...
Answer:
133.33 mph
Step-by-step explanation:
The small trick is to notice the time. Is it 8:00 AM the same day. We don't know, but we will assume it is.
So the truck was on the road for 2 hours.
The car was on the road for 2 - 1/2 = 1 1/2 = 1.5 hours.
The distance travelled was 200 miles
Solution
d = r * t
200 = r * 1.5
200/1.5 = r
r = 133.33 miles / hour
The noise you hear is a siren trying to catch up to the car.

<span>0.3046% chance of damaging at least one of five payloads.
First, determine how many standard deviations it takes for the parachute to open at 100 meters. So
200 m - 100 m = 100 m
100 m / 31 m = 3.2258
Looking up on a standard normal table, the probability of having that deviation or higher is 0.00061, or 0.061%
Since you're looking for the probability of damaging at least one of five, the easiest way of calculating that is to subtract from 1 the probability of having all five parachutes successfully deploy. So
1 - (1 - 0.00061)^5 = 1 - 0.99939^5 = 1 - 0.996953719 = 0.003046281 = 0.3046%</span>
