Paula dives into a swimming pool from a diving board 2 feet above the water's surface. She descends to a depth 7 feet below the
lys-0071 [83]

Answer:

1. 2

2. -9

3. 2+-9

4. -7

5. -15 + 8 = -7

Step-by-step explanation:

The surface of the water is 0. If Paula is above the surface of the water than she is positive. If she is below or heading down she is negative. She starts 2 feet above which is 2. She descends a total of -9 from 2 to -7. She ends up -7 or 7 feet below surface. So she travels from 2+-9 = -7.

Yolanda owes her friend $15  or -15. She earns $8 a week or +8. If she earns 8 dollars this week and pays Yolanda back then -15+8=-7. She now owes $7.

Determine is (x-3) is a factor of<br> x^3 - 5x^2 - 4x + 6 using the remainder<br> theorem:
Nutka1998 [239]

Answer:

(x - 3) is not a factor

Step-by-step explanation:

If (x - h) is a factor of f(x) then f(h) = 0

here

f(x) = x³ - 5x² - 4x + 6 , then

f(3) = 3³ - 5(3)² - 4(3) + 6 = 27 - 5(9) - 12 + 6 = 27 - 45 - 6 = - 24

since f(x) ≠ 0 then (x - 3) is not a factor of f(x)

A rectangle has a length x centimeters and a width that is equal to half its length. The perimeter of the rectangle is 50 centim
dusya [7]

Answer:

Step-by-step explanation:

Let x = length

Then width = (1/2)x

Perimeter = 2(length) + 2(width) = 54

                  length + width = 27

So, x + (1/2)x = 27

           (3/2)x = 27

                 x = 27(2/3) = 18     (1/2)x = 9

Answer:  length = 18 cm and width = 9 cm
