The calculation of the integral will give us the answer.
Amount = Int (2000e^(-0,2t))dt
With t = 0 to t = 10
A = 2000.In(e^(-0,2t))dt
Making U = -0,2t
U = -0,2t
dU/dt = d(-0,2t)/dt
dU/dt = -0,2
dU = -0,2dt
dt = dU/-0,2
_______________
Then,
A = 2000.Int (e^U).dU/-0,2
A = -10.000.Int(e^U)dU
A = -10.000.e^U
A = -10.000.e^(-0,2t) | (0,10)
A = -10.000.(e^(-2)) - [ -10.000.e^(0)]
A = -10.000.e^(-2) + 10.000
A ~ 8,646 Gallons
Answer:
y=3/2x-2
Step-by-step explanation:
Find the slope first:

Then solve for y-intercept:

Now, write out your complete equation:
y=3/2x-2
Answer:
r = 7
Step-by-step explanation:
60 = -24 + 12r
<u>+24 +24</u>
84 = 12r
84 ÷ 12 = r
7 = r
Check:
60 = -24 + 12r
-24 + 12(7)
-24 + 84 = 60
Answer:
see below
Step-by-step explanation:
Except for the stretch factor, your work is completely correct. Multiplying only the x-coordinate by a factor of 2 results in a horizontal stretch by that factor.
Your coordinates and graph are correct.
In the comparison, you just need to say what happened.
14 over 26. Because if you want to find out the probability, you need to put the number of girls over the total of students.
Hope this helps!!!:)
