I have no clue but you could ask your teacher to help u with it no jk the answer is -7
Answer: C.$10,000
Step-by-step explanation:
Assuming the interest was compounded annually, then we would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
A = $31066
r = 6.5% = 6.5/100 = 0.065
n = 1 because it was compounded once in a year.
t = 18 years
Therefore,
31066 = P(1+ 0.065/1)^1 × 18
31066 = P(1.065)^18
31066 = 3.12P
P = 31066/3.12
P = $9957.1
Approximately $10000 to the nearest dollar
Answer:
11+4x
Step-by-step explanation:
2+3(x+3)+x
Distribute 3 through the parenthesis
2+3x+9+x
Add the numbers
11+3x+x
Collect thw like terms
11+4x
It looks like the given equation says
When <em>x</em> = 0, you have
Differentiating both sides with respect to <em>x</em> gives
That is, the derivative operator distributes over sums, and the derivative of a constant is 0; apply the product rule on the first term and chain rule on the second; then use chain rule one more time.
Now plug in <em>x</em> = 0 and <em>y</em> = 5, and solve for <em>y'</em> :
It would be A. A squares width and length are the same so both the width and length can be represented with x. The problem asks to add 5 to the length and 3 to the width creating the expression (x+5)(x+3). That can then be multiplied out to get x^2+8x+15
