old (first visit): 550 grams
second visit: gained 350 grams
third visit: gained 300 grams
new: cora's kitten is now 1200 grams.
-> now, we must find the percent increase between 550 and 1200.
to find percent increase, we use this equation
new - old / old x 100
-> (1200 - 550 / 550) x 100
(650 / 550) x 100
= 1.18 x 100
<u>percent increase: 118% </u>
<u></u>
✧ hope this helped!

Answer:
3.61 seconds
Step-by-step explanation:
The bird starts 50 feet in the air, so will come down to a height of 40 feet after 3.61 seconds.
We want to solve h = 40.
40 = -16t^2 +55t +50
16t^2 -55t -10 = 0
t = (55 +√(55^2 -4(16)(-10)))/(2(16)) = (55 + √3665)/32 ≈ 3.61060
The bird will be 40 ft above the ground the first time after about 3.61 seconds.
