Answer:
F(x) = 45*x - (5/2)*x^2 + C
Step-by-step explanation:
Here we want to find the antiderivative of the function:
f(x) = 45 - 5*x
Remember the general rule that, for a given function:
g(x) = a*x^n
the antiderivative is:
G(x) = (a/(n + 1))*a*x^(n + 1) + C
where C is a constant.
Then for the case of f(x) we have:
F(x) = (45/1)*x^1 - (5/2)*x^2 + C
F(x) = 45*x - (5/2)*x^2 + C
Now if we derivate this, we get:
dF(x)/dx = 1*45*x^0 - 2*(5/2)*x
dF(x)/dx = 45 - 5*x
1. 1 hour is 3x20 minutes so distance is 3 km wi=hich is 3000 metres
2. same way as before but now 4x 1km is 4000 metres, minus the previous answer is 1000 metres.
3. 26 days x 24 hours (in one day) = 624 hours
4. A) 1 hour 45 minutes
B) 10:10, because add one hour and then minus 10 minutes (probably easiest way)

Well, first, you would fine how much she put in the bank in the first place!
250,000-96,000=154,000
Then you would do 154,000*0.02 to find how much interest is charged per month.
154,000*0.02=3080
Finally, you would multiply 3080 by 6 {because you need to account for all of the months}.
3080*6=18,480

Answer:
All positive rational numbers greater than 50
Step-by-step explanation:
Since the delivery cost is fixed per trip, the cost incurred can be represented by the equation
y(x)=8x+50 so in case Tess wants only 1 tone, the cost will be y(x)=8(1)+50=58
Therefore, it's proper to conclude that all numbers in the possible range are positive rational numbers greater than 50
Answer:
root 25
Step-by-step explanation:
root 25 is 5, and every other number may not be able to be written as a whole number (please give brainliest)
