<u>Corrected Question</u>
In the year 2009, the cost of a flat screen television can be modeled by the equation C = -10t^2 + 500 where t is the number of years since 2009. Factor this cost polynomial.
Answer:
Using express exponents, you write C=10(50-t^2)
Step-by-step explanation:
To factor the cost polynomial, , we follow these steps.
Step 1: Determine the greatest common divisor of the terms in the polynomial
The terms in the polynomial are
The greatest common divisor of is 10.
Step 2: Factor the polynomial by dividing each of the terms with the greatest common divisor obtained above.
Answer:
s = 144.64 feet
Step-by-step explanation:
Given that,
The initial speed of a car, u = 45 ft/s
Deacceleration of the car, a = -7 m/s²
We need to find the distance covered by the car travel before coming to a complete stop. let it is d.
Final velocity, v = 0
Using the third equation of motion as follows :
So, it will cover a distance of 144.64 feet.
