Depends on wether you are losing or gaining because of tax -

You would either multiply your base by 1.09 or by .91.

how would you figure out how many terminal zeroes are at the end of 1x2x3x4x5x6x7x8x9x10x11x12x13x14x15x16x17x18x19x20 WIThOUT using a calculator?
With a lot of time I think.

on a calc it is just 20! = 2.4390200817664 x 10^18

so that has 4 terminal zeros.

You taught me a new term - I had never heard of terminal zeros before.

The annual profit, p(x), in dollars of a small company varies with the number of employees, x, as p(x) = -40x^2 + 4400x. What is the range of the number of employees for which the company’s annual profit will be at least $112,000?

p(x) = -40x^2 + 4400x

-40x^2 + 4400x >= 112000

-40x^2 + 4400x - 112000 >= 0

-40x^2 + 4400x - 112000 >= 0
divide everything by 40
-x^2 + 110x - 2800 >= 0

now times by -1 but don't forget that when you multiply an inequality by a neg, you have to turn the sign around
x^2 - 110x + 2800 <= 0
now you have to factorise to get the roots. I notice straight away that -4*-7=28 and -4+-7=-11 so I know what the factors are but if you don't see this you can use the quadratic equation.

(x-40)(x-70) <=0
When x=40, or x=70 this will equal 0

consider the graph
y=(x-40)(x-70)
the equation we want will be true if y is positive
this is the equation of a concave up parabola with roots at 40 and 70 (sketch it)
So y will be positive or zero 40<=x<=70

so to make a profit of at least $112000 the company need to have between 40 and 70 employees.

If anything doesn't make sense, please post again.

Wow thank you so much! I kept trying to turn it into log form before dividing by 5 and just getting ridiculous answers. Thank you for explaining to me, I understand how to find the inverse function with a negative exponent now and it actually makes sense! Thanks again for your help, much appreciated.

square root w-8=8

(square root w)-8=8

(square root w)-8+8 =8+8

I think you can finish it . If no then post again.

D=5*e^(-0.4h)

Find h when D=2

2=5*e^(-0.4h)
divide both sides by 5
0.4 = e^(-0.4h)

ln 0.4 = lne^(-0.4h)

ln 0.4 = -0.4h

h = ln0.4 / -0.4 = 2.29072683hours

h = 2 hours and 17 minutes to the nearest minute.
-----------------------------
now looking at your specific concerns
1) what to do with the 5 when turning it into log form (hopefully you can see what happened to the 5)

2) and also how is the answer positive with the -.4h.

-0.4h is the power of e. Any positive number raised to any number (positive or negative) will be positive. e is a positive number.

I don't know how good you can manipulate indices but maybe if you think about this it might help

16^(-0.5) = 1 / 16^(0.5) = 1 / the sqrt of 16 = 1/4

Sorry it is the first one you wrote. D=5*e^(-.4h)

I just want to clarify
is it

D=5*e^(-0.4h)
or
D=5*e^(-0.4)*h = 5*h*e(-0.4) [tecnically this is what you have written]

what is two to the negative fifth power?

It is 1/ two to the positive fifth power

when you want to get rid of a negative power you swap the whole thing to the other side of the fraction line and change the negative to a positive.

When you say 5th do you mean a power of 1/5 OR do you mean a power of 5?

what is the multiplicative inverse or reciprocal inverse of 4/9

The reciprocal is 9/4
The inverse is 9/4

The reciprocal inverse makes no sense to me.

Can't you at least start it in your own calculator?

It is too huge for your calc to compute.
But, the smallest digit will be 5
