Answer: =−14a3−2a2+12
Step-by-step explanation:
−5a3−7a2+3−9a3+5a2+9
=−5a3+−7a2+3+−9a3+5a2+9
Combine Like Terms:
=−5a3+−7a2+3+−9a3+5a2+9
=(−5a3+−9a3)+(−7a2+5a2)+(3+9)
=−14a3+−2a2+12
Answer:
=−14a3−2a2+12
Answer:
x = -1/24
Step-by-step explanation:
8 - 1/3x = 16
8 × 3x - 1/3x = 16
24x - 1/3x = 16
24x - 1 = 16 × 3x
24x - 1 = 48x
1 - 24x = - 48x
1 = 24x - 48x
1 = - 24x
-1/24 = x
x = -1/24
Follow the given formula. The initial amount of money invested, P, becomes 2P (same thing as "doubles) after t years. Since compounding is quarterly, n=4. The annual interest rate is 12%. That is, r=0.12.
Then we have 2P = P (1 + 0.12/4)^(4t) and need only solve for time, t.
Simplifying the above equation: 2 = (1.03)^(4t)
We must isolate 4t, and then isolate t. To do this, take the common log of both sides of the above equation. We get:
log 2 = (4t) log 1.03. This gives us 4t = [log 2] / [log 1.03], or
4t = 23.4498
Dividing both sides by 4, we get t = 5.86 (years).
Answer:
$55
Step-by-step explanation:
1) since we are taking 50% of the price of lets find 50% of 110
so 0.50*110=55
50% of 110 is 55 hence we can subtract 55 from 110(since its getting marked down)
110-55=55
$55 is the new price
Hope this helps!
