You can imagine the wave being a circle.

The highest point on the unit circle would have the y value of 1 and since that's a quarter of a circle past, it would have a x value of pi/2

Henceforth, the first answer would be (pi/2, 1)

Taking the same before analogy, the point would be in the middle of the circle therefore it would have the y value of 0.

Since it completed a half of the circle's circumference, it would have the x value of pi.

Henceforth, the second answer would be (pi, 0)

Answer:

1. width is w. length is w + 26

$w \times (w + 26) < 2040$

3. the width must be less than 34

4. sure, if the width is 10, then the area is 360

Step-by-step explanation:

$w \times (w + 26) < 2040$

Caitlin has $5 and $10 bills that are worth $675. She has twice as many $10 bills as $5 bills. How many of each type of bill doe

Lerok [7]

Caitlin has 27 $5 bills and 54 $10 bills.

Step-by-step explanation:

Given,

Worth of $5 and $10 bills = $675

Let,

Number of $5 bills = x

Number of $10 bills = y

According to given statement;

5x+10y=675 Eqn 1

She has twice as many $10 bills as $5 bills.

y=2x Eqn 2

Putting value of y from Eqn 2 in Eqn 1

$5x+10(2x)=675\\5x+20x=675\\25x=675$

Dividing both sides by 25

$\frac{25x}{25}=\frac{675}{25}\\x=27$

Putting x=27 in Eqn 2

$y=2(27)\\y=54$

Caitlin has 27 $5 bills and 54 $10 bills.
