Answer:
7(-6)=-42
After 7 weeks the price will be reduced by 7 times $6
Thus the price will be $42
27 squared is equal to 729, and the square root of 729 is equal to 27.
Hopefully, this helps.
Answer:
f(x) = 2x^2 - 6x - 20.
Step-by-step explanation:
(-2, 0) and (5, 0) are 2 zeroes of the function so we can write the function as
f(x) = a(x + 2)(x - 5) where a is a constant.
Now as (4, -12) is a point on the graph:
-12 = a(4 + 2)(4 - 5)
-12 = a * 6 * -1
-6a = -12
a = 2.
So f(x) = 2(x + 2)(x - 5)
f(x) = 2x^2 - 6x - 20.
62.8cm^2 I think that's the answer
