Answer:
48
Step-by-step explanation:
f(x)= 1/3(4 - x)^2
f(16) = (1/3)(4 - 16)^2
f(16) = (1/3)(-12)^2
f(16) = (1/3)(144)
f(16) = 48
Answer: The required discount is $819 and the rate of discount is 20.48%.
Step-by-step explanation: Given that a home theater system is marked down from $3999 to $3180.
We are to find the discount and the rate of discount.
The discount will be given by actual price minus the marked price.
We have
Actual price = $ 3999 and marked price = $3180.
So, the discount is given by
![\textup{Discount}=\$(3999-3180)=\$819](https://tex.z-dn.net/?f=%5Ctextup%7BDiscount%7D%3D%5C%24%283999-3180%29%3D%5C%24819)
And the rate of discount is
![\textup{Rate of discount}=\dfrac{819}{3999}\times100\%=20.48\%](https://tex.z-dn.net/?f=%5Ctextup%7BRate%20of%20discount%7D%3D%5Cdfrac%7B819%7D%7B3999%7D%5Ctimes100%5C%25%3D20.48%5C%25)
Thus, the required discount is $819 and the rate of discount is 20.48%.
Answer:
B
Step-by-step explanation:
Given
P = 2(l + b) ← distribute
P = 2l + 2b ( subtract 2b from both sides )
P - 2b = 2l ( divide both sides by 2 )
= l → B
