There's ambiguity here.  Either the original expression is "5 times the square root of a" or 5 is the "index of the root."

Then "5 times square root of a" would be  5a^(1/2), or
     1/2
5a


.  On the other hand, if you meant 5 to be the "index of the root," then the correct result would be

  1/5
a



If you're left unsure of which answer is correct, try copying the original problem onto paper and then writing out the answer you believe is correct.  Upload this image to Brainly and then attach it to your question.

There are 1420 students enrolled at Senn. If 60% of these students walk to school, how many students are walking to school?
pychu [463]

Answer:

852 students walking to school

Step-by-step explanation:

Lets start with a simple example so you can get it

if 60% of 100 students walk to school that means

60 students walk to school... right??

so lets simplify it more that means you have multiplied 100 (students) by 60%

or \frac{60}{100}  (note: you can say that 60% is equal to \frac{60}{100} )

so the problem told 60% of 1420 students walk to school that means we should

do this:     1420*\frac{60}{100} = 852

Is this a linear function? One person sends an email to 2 people. Those 2 people send it to 4 people, and those 4 send it to 8 p
Mumz [18]
Yes; this is a linear function because you plug in a number and multiply it by two, so the function would be y=2x, which is linear despite the fact that it lacks a b value.

Hope this helps! :)

Firdavs [7]

Answer: D

Step-by-step explanation:

Think of it logically: A and C are not below sea level so you can cross them out. And B doesn't work because if you decrease -10 by 10 you get -20. So, D is correct.

Find the interval(s) of upward concavity on this accumulation function.
maxonik [38]

\displaystylef(x)=\int_{0}^{x^2}\sec^2(\sqrt{x})dx \\=\int_{0}^{\sqrt{x^2}}\sec^2(u)\cdot2udu \\=2\int_{0}^{\sqrt{x^2}}\sec^2(u)du \\=2\Big[u\tan(u)-\int\tan(u)du\Big]_{0}^{\sqrt{x^2}} \\=2\Big[u\tan(u)+\ln\Big(\mathrm{abs}(\cos(u))\Big)\Big]_0^x \\=2\Big(x\tan(x)+\dfrac{1}{2}\ln\Big(\cos^2(x)\Big)\Big) \\=2x\tan(x)+\ln(\cos^2(x))

Hope this helps.
