From the calculation done below, the interest when the rate is 9% is $101.25.
<h3>How interest is calculated using direct variation?</h3>
Since the interest on investment varies directly as the rate of interest, the relevant direct variation formula to use to calculate investment is as follows:
i = kr ................................. (1)
Where:
i = interest amount = $45
k = investment = ?
r = interest rate = 0.04
Substituting the values into equation (1) and solving for k, we have:
45 = k0.04
k = 45 / 0.04
k = $1,125
To find the interest when the rate is 9%, we substitute k = $1,125 and r = 9% into equation (1) as follows:
i = $1,125 * 9% = $101.25

hope this helpss
That what the answer is because on what is asking the answer is gonna be 6,1761
Answer:
Step-by-step explanation:
f(9) = |9 + 9| = |18| = 18
f(-4) = |-4 + 9| = |5| = 5
f(0) = |0 + 9| = |9| = 9
pretty boring examples as you're always taking the absolute value of a positive number.
what do you suppose f(-12) is???
f(-12) = |-12 + 9| = |-3| = 3
