Answer:
c on edg
Step-by-step explanation:
Answer:
If you need the expression: 2x^2-5x-3
If you need answers from a factored form: x=3 and x= -1/2
Step-by-step explanation:
(x-3)(2x+1)
2x^2+x-6x-3
2x^2-5x-3
1 + .3 +.07+.005 x 10 - 6
$7881.18
Step-by-step explanation:
Let the initial Investment be 
. The Interest is compounded on a monthly basis at 12% annual interest rate. After 17 years, the Investment amounts to $60,000.
As the annual interest rate is 12%, the monthly interest rate is 1%.
Since this is a compound interest problem, the total amount can be modeled as follows: 
Here 
is the interest rate, i.e 
, and t is the number of time periods, i.e 
= 
∴ Initial Investment = $7881.18

Answer:
k ≈ -0.06729
Step-by-step explanation:
The initial temperature difference is 85 -36 = 49 degrees. After 5 minutes, the temperature difference is 71 -36 = 35 degrees. The constant k is the natural log of the ratio of these temperature differences, divided by the time unit.
k = ln(35/49)/5 ≈ -0.06729
__
The equation for the temperature T of the can in the refrigerator is ...
T = 49e^(-0.06729t) +36
_____
<em>Additional comment</em>
Be careful with the sign. If you're filling in k in e^(-kt), then the sign of k will be positive. Above, we have taken the form of the exponential term to be e^(kt), so k is negative.
