Answer:
f(15) = 242
Step-by-step explanation:
Step 1: Define
f(x) = 2(4 - x)²
f(15) = x = 15
Step 2: Substitute and Evaluate
f(15) = 2(4 - 15)²
f(15) = 2(-11)²
f(15) = 2(121)
f(15) = 242
Answer:
x²-y² = 40
Step-by-step explanation:
Factorising x²-y²:
x²-y² = (x+y)(x-y)
This is due to the property that states:
a²+b² = (a+b)(a-b)
Substituting the given values into the above equation:
x²-y² = (10)(4)
= 40
Hence, x²-y² = 40

Answer:
Step-by-step explanation:
Answer:
Option D.
Step-by-step explanation:
Exchange rate from Dollars to Riyal is,
1 Dollar = 3.7 Riyals
Bill wants to exchange $11.60 for which we will use the exchange rate.
∵ 1 Dollar = 3.7 Riyals
∴ 11.60 Dollars = 3.7 × 11.60
= 42.9 Riyals
Therefore, after exchange of 11.6 Dollars Bill will get 42.9 Riyals.
Option (D) is the correct option.
