Rajeev buys good worth Rs 6650.He gets a rebate of 6% on it.After getting the rebate, he pays sales tax @10%. Find the amount he
finlep [7]

Rajeev will pay Rs 6876.10 for the goods.

Step-by-step explanation:

Given,

Worth of goods = Rs 6650

Rebate = 6%

Amount of rebate = 6% of worth of goods

Amount of rebate = \frac{6}{100}*6650=0.06*6650

Amount of rebate = Rs 399

Amount after rebate = 6650 - 399 = Rs 6251

Sales tax = 10%

Amount of sales tax = 10% of amount after rebate

Amount of sales tax = \frac{10}{100}*6251=0.1*6251

Amount of sales tax = Rs 625.10

Total amount of goods paid = Amount after rebate + sales tax

Total amount of goods paid = 6251+625.10 = Rs 6876.10

Rajeev will pay Rs 6876.10 for the goods.

What is the value of f(x) when x = 4 in the piecewise function f(x) = 2x² when x&gt;4
zepelin [54]

Answer:

16

Step-by-step explanation:

f(x) = 2x² when x>4

We cannot use this expression of f to calculate f(4)

because ,this expression define f for the value of x

that are greater (not equal) than 4.

………………………………………………………

f(x) = 4x when x ≤ 4 , here x is can be equal to 4

(notice the sign ≤ )

Therefore

f(4) = 4 × (4) = 16
