Answer:
Area of floor = 21.6m2
area of tile = 576cm2=0.0576m2
now,
number of tiles = 21.6/0.0576
= 375
Answer:
$3.35
Step-by-step explanation:
volume of balloon in the shape of sphere= 4/3 * pi * r^3 = 4.189 cubic foot

Answer:
D. y = -(x-5)(2x+1)(x+3)
Step-by-step explanation:
"r" is a zero of the polynomial when (x -r) is a factor.
The three given zeros mean that (x -5), (x -(-1/2)), and (x -(-3)) will be factors of the equation. The product of the constants in these binomials (and any vertical scale factor) must be equal to the y-intercept.
For some scale factor "a", we want ...
(a)(-5)(1/2)(3) = 15
a = 15/(-7.5) = -2
and the desired polynomial function is ...
y = -2(x -5)(x +1/2)(x +3 = -(x -5)(2x +1)(x +3) . . . . matches choice D
