You do the things in the parentheses first then multiply them by 2
Answer:
14 3/4 years
Step-by-step explanation:
Let's assume compound inflation. The appropriate formula for that is:
A = P(1 + r)^t.
If we represent current prices by P, then double that would be 2P:
2P = P(1 + 0.048)^t Find t, the time required for prices to double.
Then:
2 = 1.048^t
Taking the natural log of both sides, we get:
ln 2 = t·ln 1.048, so that:
t = (ln 2) / (ln 1.048) = 14.78
At 4.8 inflation, with annual compounding, prices will double in approx. 14 3/4 years.
Answer:
$0.50
Step-by-step explanation:
This is a simple equation. All you need to do is divide 18 by 36.
18/36 = 0.5
Slope = rise / run = Δy / Δx = (y2 - y1) / (x2 - x1) = [33 - 9] / [ (-10 - (-2)]
Slope = 24 / ( -8) = - 3
Answer: - 3
Answer:
x = -7, 7
Step-by-step explanation:
- 2x²-50 = x² -1
- 2x²-x²-50+1 = 0
- x²-49 = 0
- (x+7)(x-7)
- x = -7, 7
