Answer:
Step-by-step explanation:
A function is odd if f(-x) = -f(x)
A function is even if f(-x) = f(x)
And neither if neither are true.
In this case if we plugged in a negative x here
f(-x) = (-x)^3 - 11(-x)
f(-x) = -x^3 + 11
Therefore, this function is odd because if we pulled out a negative one again we would get back the original function. Or in other words f(-x) = -f(x) for f(x) = x^3 - 11x
Answer:
c, summing up. not the others
Answer:
Ali's heart rate is 135 beats per minute
Step-by-step explanation:
Let
x ----> Ali's heart rate
y ----> Ben's heart rate
we know that
isolate the variable x
----> equation A
we have
---> equation B
Solve the system by substitution
substitute equation B in equation A
Solve for x
simplify
therefore
Ali's heart rate is 135 beats per minute
If she has only done 25% (a quater of her sit ups). She needs the other “3 quaters” of situps. So the 50 done + 50+50+50=200 she plans to do 200 situps
So your present value is 7750. this is what you have now. they give you the intesrest rate which is 4% and how the amount of year is 5.
recall the formula for a compounded continously is
P×e^(r×t)
the answer is 7750×e^(.04×5)
