Answer: Absolutely Never. No. He didn't do it correctly. Don't you do it.

I have never seen that error on Brainly before, although while I was teaching, I saw it enough times that I could always bet my math classes that I would see that error 100 times by the end of term. I always promised a case of beer for their grad (which would have given them 1 beer each). I never had to pay. They always made the error 100 times as a class.

Micah CANNOT cancel across a plus sign when going from the numerator to the denominator. You have to be able to take an x^2 out of every term or no term. Micah is totally wrong. Don't, whatever you do, follow his example.

Here is the only condition which will permit you that kind of cancellation.

\dfrac{x^4 + 5x^3 + 10x^2 }{3x^4 + 6x^2} = \dfrac{x^2(x^2 + 5x + 10)}{x^2(3x^2 + 6) }

Now Micah can cancel out the x^2. That is the only condition that will work.

the proper angle for a ladder is about 75 degrees. from the ground. suppose you have a 9 foot ladder. how far from the house sho
icang [17]

ANSWER:

2.33 foot

STEP-BY-STEP EXPLANATION:

We can calculate the distance from the staircase to the wall, by means of the trigonometric cosine ratio, which is the following:

\begin{gathered} \cos \theta=\frac{\text{ adjacent}}{\text{ hypotenuse}} \\ \theta=75\text{\degree} \\ \text{ hypotenuse = 9 foot} \\ \text{adjacent = x} \end{gathered}

Replacing and solving for x:

\begin{gathered} \cos 75=\frac{x}{9} \\ x=9\cdot\cos 75 \\ x=2.33 \end{gathered}

The distance would be 2.33 foot

Ryder Industries is considering a project that will produce cash inflows of $92,000 a year for five years. What is the internal
RSB [31]

Answer:

20.02%

Step-by-step explanation:

Formula : NVP = 0 =-P_0 + \frac{P_1}{(1+IRR)} + \frac{P_2}{(1+IRR)^2} + . . . +\frac{P_n}{(1+IRR)^n}

P_0 = 275000

n = 1,2,3,4,5

Substitute the values in the formula :

0 =-275000 + \frac{92000}{(1+IRR)} + \frac{92000}{(1+IRR)^2} + \frac{92000}{(1+IRR)^3}+\frac{92000}{(1+IRR)^4}+\frac{92000}{(1+IRR)^5}

275000 = \frac{92000}{(1+IRR)} + \frac{92000}{(1+IRR)^2} + \frac{92000}{(1+IRR)^3}+\frac{92000}{(1+IRR)^4}+\frac{92000}{(1+IRR)^5}

Solving for IRR using calculator

IRR = 20.02

Hence the internal rate of return if the initial cost of the project is $275,000 is 20.02%
