2. Write an expression for the perimeter of a rectangle with a length of
solmaris [256]

Answer:

<h2><u><em>2 × [(3x² + x + 2) + (-x² – 5x + 1)] =</em></u></h2>

Step-by-step explanation:

Write an expression for the perimeter of a rectangle with a length of

(3x² + x + 2) and a width of (-x² – 5x + 1).

P = 2 × (L + W)

<u><em>2 × [(3x² + x + 2) + (-x² – 5x + 1)] =</em></u>

if you want the result:

4x²−8x+6

Given: circle k(O), m LM = 164°, m WK = 68°, m∠MLK = 65°. Find: m∠LMW
Musya8 [376]

Answer:

The measure of angle LMW is m\angle LMW=67\°

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of arc MW

we know that

The inscribed angle measures half that of the arc comprising

so

m\angle MLK=\frac{1}{2}[arc\ MW+arc\ WK]

substitute the given values

65\°=\frac{1}{2}[arc\ MW+68\°]

130\°=[arc\ MW+68\°]

arc\ MW=130\°-68\°=62\°

step 2

Find the measure of arc LK

we know that

arc\ LM+arc\ MW+arc\ WK+arc\ LK=360\° -----> by complete circle

substitute the given values

164\°+62\°+68\°+arc\ LK=360\°

294\°+arc\ LK=360\°

arc\ LK=360\°-294\°=66\°

step 3

Find the measure of angle LMW

we know that

The inscribed angle measures half that of the arc comprising

so

m\angle LMW=\frac{1}{2}[arc\ LK+arc\ WK]

substitute the given values

m\angle LMW=\frac{1}{2}[66\°+68\°]=67\°

Find ModifyingBelow lim With h right arrow 0limh→0StartFraction f (x plus h )minus f (x )Over h EndFraction f(x+h)−f(x) h for th
UkoKoshka [18]

Answer:

Answer is 88

Step-by-step explanation:

We have Given function

f(x)=88x-77

we have to find f'(x) at x=3  Where f'(x) shows derivative of the given function.

This means we need

f'(3)=?

So By definition of the Derivative that is

f'(x)=lim(h---->0)(f(x+h)-f(x))/h

so this our definition of derivative of the function

Now We have to find out at x=3, So By putting x =3 in definition ,We get

f'(3)=lim(h---->0)(f(3+h)-f(3))/h

   Here lim(h--->0) means limit h approaches to zero(right arrow 0limh→0)

     =lim(h---->0)((88(3+h)-77))-(88(3)-77))/h

     =lim(h---->0)((264+88h-77)-264+77)/h

     =lim(h----->0)(264+88h-77-264+77)/h

now by performing simple arithematic we get result

f'(3) = lim(h---->0)(88h/h)

f('3) = lim(h---->0)(88)

here we use law of the limit we limit of the constant is that constant

lim(h----->0)c=c

so

f'(3)=88

So this our answer
