Explanation:

a) The more like a cube or a ball the figure is, the smaller its surface area.

b) Solids with smaller surface area have nearly the same dimension in every direction.

c) Solids with larger surface area have a very high ratio between the largest dimension and the smallest dimension. The flatter or more string-like the figure is, the larger its area.

Ricardo throws a stone off a bridge into a river below. The stone's height (in meters above the water), xxx seconds after Ricard

Dominik [7]

For this case we have the following function:
w (x) = - 5 (x-8) (x + 4)
Rewriting we have:
w (x) = - 5 (x ^ 2 + 4x - 8x - 32)
w (x) = - 5x ^ 2 - 20x + 40x + 160
w (x) = - 5x ^ 2 + 20x + 160
Then, deriving we have:
w '(x) = - 10x + 20
We equal zero and clear x:
0 = -10x + 20
10x = 20
x = 20/10
x = 2 seconds
Substituting values:
w (2) = - 5 (2-8) (2 + 4)
w (2) = - 5 (-6) (6)
w (2) = 180 meters
Answer:
The maximum height that the stone will reach is:
w (2) = 180 meters

What are the possible values of x if (4c-5)^2= 49?

kykrilka [37]

Answer:

c = 3 c = -1/2

Step-by-step explanation:

(4c-5)^2= 49

Take the square root of each side

sqrt((4c-5)^2)= ±qrt(49)

4c-5 = ±7

Separate into two equations

4c-5 = 7 4c-5 = -7

Add 5 to each side

4c-5+5 = 7+5 4c-5+5 =-7+5

4c =12 4c = -2

Divide by 4

4c/4 = 12/4 4c/4 = -2/4

c = 3 c = -1/2
