Which of the following is a function equivalent to f(x) = 4(1.8)2x?f(x) = 4(3.24)x
f(x) = 4(3.24x)
f(x) = 12.96x
f(x) = 51.84x
Answers
f(x) = 4 * (1.8)^(2x)
f(x) = 4 * 3.24^x
f(x) = 4 * (3.24)^x
The correct result would be f(x) = 4(3.24)x.
Answer:
A

Option D is the correct answer.
What is a function?
A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To find (C o D)(x), we need to substitute d(x) into c(x) and simplify the resulting expression.
First, we have:
C(D(x)) = 4D(x) - 2
Next, we substitute d(x) for x in the expression for D(x):
D(x) = x² + 5x
So,
C(D(x)) = 4(x² + 5x) - 2
Simplifying, we get:
C(D(x)) = 4x² + 20x - 2
Therefore,
The value for the compositefunction is 4x² + 20x - 2.

Explanation: We know this because 45% off means it was at 55% of its value. 55% = .55, so we can divide the sale price by the percent of its value. 115.25 / .55 ~=~ (is around) 209.55. The answer is $209.55.
Final answer:
The original price of the tablet, before the 45% off was applied, was approximately $209.54.
Explanation:
To find the original price of the tablet, we have to understand that the 45% off coupon reduced the price to $115.25, which represents 55% (100% - 45%) of the original price. Hence, we can set up the maths, using the principle of the proportion as follows:
55/100 = $115.25/ORIGINAL PRICE
Cross multplying the fractions and dividing, gives us the original price:
ORIGINAL PRICE = (100 * $115.25)/ 55 = $209.54 rounded to the nearest cent.
So, the original price before the discount was applied should have been approximately $209.54

What is a right triangle?
A triangle with one of its angles measuring 90° is known as a right triangle.
Given a right triangle with a hypotenuse of length 58 and a leg of length 32.
Use the sine rule:
(sin90°) / 58 = (sinx) / 32
sinx = 32/58
x = sin⁻¹ ( 32/58)
x = 33.49°
Hence, the value of x is 33.49°.
