Answer:
Step-by-step explanation:
- Since 2 opposite add up to 0,remove them from the expression (+4ab, - 4ab)
2. Calculate the product
Answer:
3
Step-by-step explanation:
Answer:
d = 5t + 20
Step-by-step explanation:
d represents the distance and t represents the time, in hours
Let he equation which model this situation ⇒ d = a t + b
Where a and b are constant.
Let the gas station is the starting point
So, at gas station t = 0 , d = 20
∴ 20 = 0 * a + b ⇒ b = 20
When he reaches home 2 hours later notes that he has traveled 30 miles.
and with substituting with b = 20
∴ 30 = 2 * a + 20
2a = 30 - 20 = 10 ⇒ a = 10/2 = 5
∴ d = 5t + 20
The equations that can be used to model this situation <u>d = 5t + 20</u>
Felicia has 96 coins because 30+20+30= 80.And 80+6=86. 86+10=96.
I hope I helped! :)
Given v=31 and s=0
<span>H(t) = -16t2 + vt + s
</span>
H(t) = -16t^2 + 31t
dH/dt = -32t + 31
<span>At the maximum height, dH/dt = 0
-32t + 31 =0
t = 31/32 = .96875
substitute back to H(t)
</span>
H( .96875) = 15.0 ft
ans is C
