Answer:
15x/2*4
Step-by-step explanation:
Answer:
<u>The correct answer is B. 3/4</u>
Step-by-step explanation:
In the expression 5n - 2m/7+ 3/4, what is the constant?
Let's analyze the coefficients, variables, operators and constants, as follows:
A. Coefficients:
5 is coefficient for n and 2/7 is coefficient for m
B. Variables:
n and m
C. Operators:
- between 5n - 2m/7
+ between 2m/7+ 3/4
D. Constant:
3/4 that is not affected by any variable
<u>The correct answer is B. 3/4</u>
First
224-108=116miles left
And 4 days left
116/4
=29 miles each day
Congrats on making it to integrals!
Basically you need to integral your function because integral rate in respect to time = total amount.
Also your bounts are (2001-1990,2006-1990)=(11,16)
Thus we take integral like:
int(11,16)(928.5e^(0.0249x))=
(11,16)928/0.0249e^(0.0249(x))-928/0.0249e^(0.0249(x))
(You can check this by taking its derivative and seeing if you get the original function)
928/0.0249e^(0.0249(16))-928/0.0249e^(0.0249(11))=6498.1
The number of gallons of water in the tank at t=10 is
... W(10) = 160,000 -10(8000 -10) = 80100
The number of gallons of water in the tank at t=10.5 is
... W(10.5) = 160,000 -10.5(8000 -10.5) = 76110.25
The rate of change over the interval is
... (W(10.5) - W(10))/(10.5 - 10) = (76110.25 - 80100)/(0.5) = -7979.5
The average rate of change in the number of gallons of water in the tank over the interval is -7979.5 gal/min.
The sign is negative, so the amount of water is decreasing.
