Answer A
-3 times 4=-12 12 limbs lost in 4 days Step-by-step explanation: A zombie lost 3 limbs each day for 4 days We need to frame the equation A zombie lost 3 limbs. It means 3 is negative because it says lost 3 limbs lost for 4 days So we need to add -3 , four times -3+(-3)+(-3)+(-3)= -12 We can also write equation as -3 \ times \ 4=-12 -12 represents the number of limbs lost in 4 days 12 limbs lost in 4 days

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.
