Answer:

B) -5, 5, -7, 7           

Step-by-step explanation:

3x² - bx + 2

factor:

(3x - 2 )(x - 1) = 3x² - (5)x + 2      so 5 does work

(3x - 1 )(x - 2) = 3x² - (7)x + 2      so 7 does work

(3x + 2 )(x + 1) = 3x² + 5x +2    =    3x² - (-5)x + 2      so -5 does work

(3x + 1 )(x + 2) = 3x² + 7x + 2   =    3x² - (-7)x + 2      so -7 does work

Builders are covering a wall that is 4 meters tall and 7 meters wide with bricks. They will cover the entire wall except for a s
marin [14]

Answer:

24 m^2

Step-by-step explanation:

There are two areas to consider here:  first, the area of the wall, and second, the area of the window.  We answer this question by finding these two areas and subtracting the area of the window from the area of the wall.

Wall area:  (4 m)(7 m) = 28 m^2

Window area:  (2 m)(2 m) = 4 m^2

Net area of wall, to be covered in brick:

28 m^2 - 4 m^2 = 24 m^2

the function h(t)=-16t2+144 represents the height, h(t), in feet, of an object from the ground at t second after its dropped. A
blagie [28]
The domain is the limits of the function. Since time doesnt go negative, start with 0. At time 0, the height is

-16(0)^2 + 144 = 144ft

Then, solve for t to find the upper limit for t, which is when the height is zero (since you're dropping the object).

-16t^2 + 144 = 0
-16t^2 = -144
t^2 = 9
t = sqrt(9)
t = 3

The domain is 0 to 3 seconds.
