Answer: -2
Y = x(x+3)
Y = (-2)((-2)+3) * Distribute*
Y = 4 - 6
Y = -2
Answer:
18 days
Step-by-step explanation:
1 1/4 hours each day and 22 1/2 hours so far, so we divide 22 1/2 by 1 1/4
22 1/2÷ 1 1/4
=45 ÷ 5
2 ÷4
= 45 ×4
2 ×5
= 9×2
= 18
Answer:
22.05
Step-by-step explanation:
21/2 has 5 halves
10.5 divided by 5= 2.1
2.1= 1/2 2.1 x 10 = 21
2.1 / 2 = 1.05
21 + 1.05= 22.05
Answer:
t = 25.1seconds
Step-by-step explanation:
X(t)= 16cos75°t
Y(t)= 6 + (Vosin75°t - 16t^2)
Converting 78 yards to feet :
1 yard = 3 feet
78feet =?
78×3=234 feet
Y(t)= number of feet above the ground at t seconds
VoCos75° t = 234
t = 234/(VoCos75°)
At this time,4 = y(234/VoCos75°)
4 = 6 + VoSin75°(234/VoCos75) - 16(234/VoCos75°)^2
Vo= 140.66ft/s
Time,t= 234/(140.66× Cos75°)
t = 25.087seconds
t= 25.1 seconds (1 decimal place)
There are 120 female rabbits and 30 male rabbits because 30 times 4 is 120 and 120 plus 30 is 150
