11 - 5 = 6

x = 6

I sent something 

For the function  N(t)  =  2500 + 2t⁴,

                          N'(t)  =  8t³

                  so    N'(5)  =  8·5³  =  8·125  =  1000

Okay... I will go ahead and post this one

How many   21.98 inches   are in   10,000 miles ?

\(\frac{10,000 \text{ miles}}{21.98 \text{ inches}}=\frac{10,000\text{ miles}\,*\,63,360\text{ inches per mile}}{21.98\text{ inches}}=\frac{633,600,000\text{ inches}}{21.98\text{ inches}}\approx28,826,205.64\)

The meaning to life may still be unknown. But according to google, the answer to life, everything, and the universe = 42.

When put into the calculator, the square root of 0.81237 = 0.9013157049558162. Even I am a little confused, as I have not learnt much about this even though I'm already in high school.

21.60 or 21.6 divided by 1.35 equals 16.

9 + 10 = 19. If you are having trouble, try counting using crayons, your fingers and toes, toothpicks, etc. You can also try to input that into a calculator and it will solve the expression for you.

The unit rate is $9 per hour. If you are having trouble understanding, remember problems usually give hints. Two big example of hints for unit rates are the words "per" and "each." When something is taken away or added "per" hour, minute, second, week, day, etc. that is usually a unit rate.

9 dollars/hour

I recommend using a compass, just like hectictar said. If you don't have own, practice drawing circles by moving the pencil around one point on a paper. If that still doesn't work, hold down the pencil on a part of a paper, preferrably the middle, at an angle. Then, turn the paper around either clockwise or counterclockwise. Just don't hold the pencil at a big angle or the circle will be too big. Good luck!

I have to solve for the last one which i needed help on, hectictar was helping..

No I have to solve for those umm

Hectictar knows.. 

Are we supposed to see an image, NSS??

I was right when I just solved it!! omg yay i followed how you did the last one and came up with this same answer yess

For this one,  we can use the same set up as last time.

How many   75.36 inches   are in   10,000 miles ?

\(\frac{10,000 \text{ miles}}{75.36 \text{ inches}}\,=\,?\)

We need to convert 10,000 miles into inches.....and..    1 mile = 63,360 inches

\(\frac{10,000 \text{ miles}}{75.36 \text{ inches}}=\frac{10,000\text{ miles}\,*\,63,360\text{ inches per mile}}{75.36\text{ inches}}=\frac{633,600,000\text{ inches}}{75.36\text{ inches}}\approx8,407,643.312\)

The exact same way you just said. 7/14.

Thank you thank you so much!! It did make sense

F=m(a) is mass =2kg and acceleration= 5m/s^2 

F =m x a

F =2 x 5 =10 kg.m/s^2 =10 newtons of force.

So what should I do for E?

Ah ha! I got it after trying for some time... It's 78!

Flip your monitor upside down. What pattern do you see now? When you orient the numbers in the correct position, this is what you see...

\(86, ?,88,89,90,91\)

The numbers are going in ascending by one each time. The ? is clearly 87. Let's flip this number back around to see what it looks like. Flip the order to make the number look like it would in the sequence. You get 78!

How many   94.2 inches   are in   10,000 miles?

\(\frac{10,000 \text{ miles}}{94.2 \text{ inches}}=\,?\)

We need to convert 10,000 miles into inches.....and..    1 mile = 63,360 inches

\(\frac{10,000 \text{ miles}}{94.2 \text{ inches}}=\frac{10,000\text{ miles}\,*\,63,360\text{ inches per mile}}{94.2\text{ inches}}=\frac{633,600,000\text{ inches}}{94.2\text{ inches}}\approx6,726,114.65\)

I hope this made sense!
