You drop a feather from a height of 160 centimeters. The function h= -16x^2 + 160 represents the height H (in centimeters) of the feather after x seconds. How long does it take the feather to touch the ground?

3.16

Step-by-step explanation:

At the ground, h = 0.

h = -16x^2 + 160

0 = -16x^2 + 160

16x^2 = 160

x^2 = 10

x = +\- sqrt(10)

Since we cannot have a negative time, we discard the negative answer.

3.16 seconds

idk but i found this "the graph of y = f(x-2) is the graph of y = f(x) translated two units rightward.  

so, since the point (9,2) lies on the graph of y = f(x), the point (11,2) lies on the graph of y = f(x-2)."

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
