Answer:

The maximum revenue will be R=\$25,000 at price p=\$100.

Step-by-step explanation:

Given:

R=-2.5p^2+500p

Find the vertex of the parabola represented by given equation:

p_v=\dfrac{-b}{2a}=\dfrac{-500}{2\cdot (-2.5)}=\dfrac{500}{5}=100

When p=\$100, then

R=-2.5\cdot 100^2+500\cdot 100=-2.5\cdot 10,000+50,000=-25,000+50,000=25,000

The maximum revenue will be R=\$25,000 at price p=\$100.

One of the slowest fish is the blenny
Gwar [14]

Answer:

It swims 1.75 miles in 3.5 hours. X stands for hours so x=3.5. Y stands for miles so y=1.75.

Step-by-step explanation:

your equation is y=0.5x

we know x=3.5

so y= 0.5(3.5)

solve and you get y= 1.75

so in (x,y) intercept format (3.5,1.75) and you can make a graph and label your x intercepts hours and your y intercepts miles traveled.

Given: PQ = RS, QR = 11, QS = x + 19, and RS = 2X. Find QS.<br> Can someone help
nalin [4]

QS =25

Step-by-step explanation:

QR + RS = QS

18 + (x-11) =2x-11

7 +x =2x -11

18=x

Plug in x

2(18) -11

36-11

QS=25

18 + (18-11) = 2(18)- 11

18+ 7 = 36 -11

25= 25

True

Answer:

QS + QR > RS

QR + RS > QS

RS + QS > QR

Step-by-step explanation:

Hope it helps you!

What is an equation of the line that passes through (2,2) and is parellel to the line y=7x
laila [671]

Answer:

Therefore, equation of the line that passes through (2,2) and is parellel to the line y=7x is y=7x-12

Step-by-step explanation:

Given:

a line y=7x

To Find:

Equation of line passing through ( 2, 2) and is parellel to the line y=7x

Solution:

y=7x     ...........Given

Comparing with,

y=mx

Where m =slope

We get

Slope = m = 7

We know that parallel lines have Equal slopes.

Therefore the slope of the required line passing through (2 , 2) will also have the slope = m = 7.

Now the equation of line in slope point form given by

(y-y_{1})=m(x-x_{1})

Substituting the points and so we will get the required equation of the line,

(y-2)=7(x-2)=7x-14\\\\y=7x-12......Equation\ of\ line

Therefore, equation of the line that passes through (2,2) and is parellel to the line y=7x is y=7x-12

Solve a-d please i really dont understand
valkas [14]
So i think what you do is if you make a number line like this:

1...2...3...4...5...6...7...8

you have to find out how many numbers are in between 4 and 7, so I would be 3 because there are 3 numbers I between 4-7.

so

a) 3
b) 6
c) 14
d) 8
