Answer:
The answer is 4 + √15 .
Step-by-step explanation:
You have to get rid of surds in the denorminator by multiplying it with the opposite sign :







Well 1/40 is 0.025 so that should be the write fraction to use
<span>Okay, pretend the number equals X,
so x is 35%, and that would equal 7, so then
x is still 35/100 = 7
x = 7 which is 100/35
x = 700/35
x = 20
then you get the number = 20
I hope this was helpful, and good luck! :P</span>
At x = 0, y-coordinate is at -4 so that means f(0) = -4
Now for f(x) = 4, we need to find any x-coordinates such that y-coordinates is 4.
There are two possible answer: x = -8 and x = 8
So x = -8, 8
Hope this helps.
Let the model for the change in water vapor be
y = x^3 − 8x^2 + 15x
to find the x intercepts we can factor this expression
x^3 − 8x^2 + 15x = x(x−3)(x−5)
the x intercepts are 0, 3, 5
Hope this helps!
