Answer:

Max

Step-by-step explanation:

y" = -2

Basically is a constant value of -2, which doesn't depend on x.

Find the turning point using y' = 0.

y' = 4 - 2x = 0

4 - 2x = 0

x = 2

So the turning point is at x = 2,

y = 5 + 4(2) - 2² = 9

(2,9) is the turning point

For the nature (max/min):

y" = -2

Since y" < 0, it is a maximum turning point

Answer:

Step-by-step explanation:(a)

1.65p+1.36j=118.17 and p+j=79

We can say p=79-j and sub this value in first equation

1.65(79-j)+1.36j=118.17

130.35-1.65j+1.36j=118.17

-0.29=-12.18

j=42, p=79-j, p=79-42=37

(b)

1.65(37)=61.05 and 1.36(42)=57.12

Sanchez class earned more selling pies.

(c)

61.05-57.12=3.93

So Sanchez class made $3.93 more than Kelley class.

Penny reads 13 pages in 1/2 hour. What is the unit rate for pages per hour? For hours per page? How many hours per page

horsena [70]

Answer:

13 pages : 1/2 hour Multiply both sides by 2

26 pages : 1 hour ------>> 26 pages/hr

Flip over 26 pages/hr ----->>> hr / 26 pages = 1 hr / 26 pages

Split up the fraction: (1/26) hr / page

Answer:

A. 15, 20, and 25

Step-by-step explanation:

Note that 3-4-5 is a pythagorean triple via following:

$\sqrt{ (3^2 + 4^2 )} = 5^2$

Dividing 15, 20, and 25 by 5 nets you the pythagorean triple 3-4-5.
