Aparachutist jumps from an airplane and immediately opens her parachute. her altitude in metres, after t seconds, is modelled by the equation y = -11t + 500. a second parachutist jumps 5 secs later and free falls for a few seconds. his altitude during this time is modeled by the equation y = -4.9 (t-4)^2 + 500. when does he catch up to the first parachutist? (hint: when do they meet in the air? )

They meet in air after 1.6 seconds

Step-by-step explanation:

We have the equations that model the altitude of both parachutist:

(1)

(2)

Both parachutists meet in the air when :

(3)

Rearranging the equation:

(4)

(5)

Finding the positive solution for with the quadratic formula , where , , :

 This is the time when both parachutists meet

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.
