Answer:
480 ...12%9 of 8000 ÷2...
The answer is <span>D. $661.55
</span>
A = P * eᵃˣ
A - the future value
P - the principal
a - the rate
x - the period of time
We know:
A = ?
P = $500
a = 4% = 4%/100% = 0.04
x = 7
A = P * eᵃˣ
A = 500 * e⁰.⁰⁴*⁷
A = 661.55
We take the equation <span>d = -16t^2+12t</span> and subtract d from both sides to get
0<span> = -16t^2+12t - d
We apply the quadratic formula to solve for t. With a = -16, b = 12, c = -d, we have
t = [ -(12) </span><span>± √( 12^2 - 4(-16)(-d) ) ] / [2 * -16]</span>
= [- 12 ± √(144-64d) ] / (-32)
= [- 12 ± √16(9-4d)] / (-32)
= [- 12 ± 4√(9-4d)] / (-32)
= 3/8 ±√(9-4d) / 8
The answer to your question is t = 3/8 ±√(9-4d) / 8
Option 2 is the correct option
Step-by-step explanation:
Step 1 :
Given expression : (x + 12)(x - 12)
We need to find the expression from the given options which matches the given expression
Step 2 :
The given expression is of the form (a+b)(a-b)
where a = x and b = 12 here
The product of this is given by formula
(a+b)(a-b) = (a² - b²)
Substituting the value of a and b in formula we get
(x + 12)(x - 12) = x² - 12² = x² - 144
Hence option 2 is the correct option from the given list.
Step 3 :
Answer :
Option 2 is the option which matches the given expression
