<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:
-
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m = =
= 5
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
