47400, because you would round the seven up to ten to move it up to 47400 because 90 is the last ten out of 100 so you move up one in the hundreds place since there is no more room in the tenths place.
Answer:
Mr. Porter's claim was not correct and it will be a 21% increment.
Step-by-step explanation:
The value of the house when Mr. Porter bought the house was d.
The present value of the house is given by d + 0.21d = 1.21d.
Hence, the increase in the value of the house is 0.21 d and the final value of the house is 1.21d.
So, if Mr. Porter claims that the value of his house has increased by 121%, then his claim is wrong. The increase in value is only by 0.21d i.e. by 21% and after this increment, the value becomes 1.21d i.e. 121%.
Therefore, his claim is not correct and it will be a 21% increment. (Answer)
The output value of f(3) in the given function f(x) = 2x² + 5√(x-2) is 23.
<h3>What is the output value of f(3) in the given function?</h3>
Given the data in the question;
- Function: f(x)= 2x²+5√(x-2)
- f(3) = ?
To determine the output value, we replace the variable x with 3 in the given function.
f(x) = 2x² + 5√(x-2)
f(3) = 2(3)² + 5√(3-2)
We simplify
f(3) = 2(9) + 5√(1)
f(3) = 18 + 5√(1)
f(3) = 18 + 5(1)
f(3) = 18 + 5
f(3) = 23
Therefore, the output value of f(3) in the given function f(x) = 2x² + 5√(x-2) is 23.
