What we know :
After m minutes, and adult blinks about 10m+3 times.
1 hour= 60 minutes

What we need to find:
About how many times does an adult blink in 3 minutes? In 2hours?

m=3
f (m)=10m+3
f (3)=10 (3)+3
=30+3
=33
An adult blinks 33 times in 3 minutes

2hours=2×60=120minutes

f (120)=10 (120)+3
=1200+3
=1203

An adult blinks 1203 times in 2 hours.

Which expression is equivalent to 4 sqrt 16x^11y^8/ 81x^7y^6 Assume x> 0 and y=0
Romashka [77]

One interpretation of your intent would be as follows:


                 16x^11y^8

Find 4 √ [-----------------]. Is that what you meant?

                   81x^7y^6

                                                                4*x^5*√x*y^4

If so, then the correct result would be 4 ---------------------

                                                                  9*x^3*√x*y^3


and this could be reduced to:


       4*x^5 * y^4 * √(x)     4*x^2*y

4 --------------------------- = -------------

      9*x^3*y^3 √(x)               9

Please help!!!!!!!!!! !!
mestny [16]

Answer:

The ~length~ is ~9.6~ units ✔︎

༄❁༄❁༄❁༄❁༄

a=8\\b=2\\c=?\\d=?\\e=5

Using~ Pythagorean ~theorem:

c^2=a^2+b^2

c^2=(8)^2+(2)^2

\sqrt{c^2} =\sqrt{68}

c=\sqrt{68} ~or~2\sqrt{17}

»»---------------------►

d^2=c^2+e^2

d^2=(2\sqrt{17})^2+(5)^2

d^2=68+25

\sqrt{d^2} =\sqrt{93}

d=\sqrt{93} ~or~9.6

So, your~ answer ~is ~9.6

Three highways connect the centers of three towns and
Vera_Pavlovna [14]

we know that

The circumcenter of a triangle is the point where the perpendicular bisectors of the sides intersect. It is also the center of the circumcircle, the circle that passes through all three vertices of the triangle

The distance of the circumcenter to the vertices of the triangle is equal to the radius of the circle

see the attached figure to better understand the problem

therefore

the answer is

The cell phone company must be place the new cell tower in the circumcenter of the triangle formed by the center of the three towns
