Answer: The correct answer is: [D]: "8" .
Step-by-step explanation:f y varies inversely with x; then y = k/x ; with "k" being the "constant" in this equation.
You can find the constant by substituting the values given: x = 16, f(x) = y = 2 ;
So, f(x) = y = 2 = k/16 ;
→ 2 = k / 16 ;
Solve for the constant; "k" ;
Multiply EACH SIDE of the equation by "16"
→ 16* (2) = (k / 16) * 16 ;
→ 32 = k ;
↔ k = 32 ;
As such, we can write the equation:
y = k/ x ; as:
→ y = 32/ x ;
Since we are given: "x = 4" ; Plug in that value; and solve for "y" ;
y = 32/4 = 8 .
y = 8 .
y = f(x) ;
So; f(x) = 8 ; which is: Answer choice: [D]: "8" .
Answer:
P = $6923
Step-by-step explanation:
The simple interest formula is given by
1) I = principal *interest rate * time period
where I is the interest
The amount due after the time period is given by:
2) T = principal + I
After three months, you have $9.000, so T = 9000. The present value P is the principal. We have that:
9000 = P + I
I = 9000 - P
In our problem, we have that the time period is 3 months and out interest rate is 10%.
Replacing in 1)
9000 - P = P*0,1*3
9000 = 0.3P + P
1.3P = 9000
P = $6923
So the present value P is $6923
