Answer:

maximum area will be 1058 square yards

maximum height will be 81 feet

Step-by-step explanation:

P = 2L +2W

but in this case it will be P= L+2W and P=92 yards

L+2W = 92

Solve for L , L = 92-2W

The area of rectangle A = L x W

Plug in L and simplify: A = (92-2W)W =92W -2W²

Plot in your calculator and look for maximum so when the width is 23 yards maximum area will be 1058 square yards.

Second problems is the maximum height of the rocket. Maximum will be at the vertex of the upside-down parabola.

Find the real numbers x and y.<br> 27+yi= 11-x + 4i

Korvikt [17]

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \:x = -16$

$\qquad \tt \rightarrow \: y =4$

____________________________________

$\large \tt Solution \: :$

$\qquad \tt \rightarrow \: 27 + yi = 11 - x + 4i$

$\qquad \tt \rightarrow \: yi + x = 11 + 4i - 27$

$\qquad \tt \rightarrow \: x + yi = - 16 + 4i$

By equating both equations we get :

$\qquad \tt \rightarrow \: x = - 16$

$\qquad \tt \rightarrow \: y = 4$

An online video streaming service offers two plans for unlimited streaming. Plan A has a one-time $25 membership fee and is $8 p

Zanzabum

Answer:

The answer is that both plans are equal.

Step-by-step explanation:

you start by putting the plans into an equation then you set them equal to each other. you need to assign a variable for the number of months. we'll call it M. It would look like this:

plan A - 25 + 8M

plan B - 5 + 12M

25 + 8M = 5 + 12M

Then you solve which looks like this:

25 + 8M = 5 + 12M

-8M -8M

25 = 5 + 4M

-5 -5

20 = 4M

/4 /4

5 = M

Now we aren't done after finding out what M equals. We still need to know what each plan will cost. So, we substitute what M equals into the equation. if they both end up equaling the same thing then its equal. if you get two different numbers they aren't. it would look like this:

25 + 8(5) = 5 + 12(5)

25 + 40 = 5 + 60

65 = 65

They are equal. Both plans will cost 65 dollars.
