the answer would be -\frac{23}{56} because you would need to find the LCD, which in this case would be 56 and you solve from there.

A certain company's main source of income is selling cloth bracelets. The company's annual profit (in thousands of dollars) as a
tester [92]

Answer:

8 thousand dollars

Step-by-step explanation:

The company's annual profit (in thousands of dollars) as a function of the price of a bracelet (in dollars) is modeled by: P(x)=-2x^2+16x-24

To find maximum profit , we need to find out the vertex

x coordinate of vertex formula is -b/2a

P(x)=-2x^2+16x-24

a=-2  and b = 16

x= \frac{-b}{2a}= \frac{-16}{2(-2)} = 4

Now we plug in 4 for x  and find out P(4)

P(x)=-2(4)^2+16(4)-24= 8

So the maximum profit the company can earn is 8 thousand dollars when price = $4

Answer is choice B

The ratio of the sides (first to the second) is 11/9 since we divide 22/18 and reduce that fraction

Once we know the scale factor is 11/9, we square it to get (11/9)^2 = 121/81 which is the ratio of the first area to the second area
