Answer:
3.5 m/s
Step-by-step explanation
Remove brackets
d = t^2 + 0.2t + 3.3t + .66
Combine
d = t^2 + 3.5t + .66
The initial velocity is 3.5
Answer:
Line

Step-by-step explanation:
We are given that


Subtract one equation from other then we get



Substitute the value of x in first equation then we get

Hence, the solution
is the intersection point of two line equations .
Answer:Line
intersects line 
f = t = n five ten and twenty
5n + 10n + 20n = 560
35n = 560
n = twenty dollar coins = 16
The answer is A! Hope you have a nice day <3
Answer:
t = (p - 1/2)/3
Step-by-step explanation:
p = 4t + 1/2 - t
combine like terms:
p = 3t + 1/2
subtract 1/2 from each side of the equation:
3t = p - 1/2
divide both sides by 3:
t = (p - 1/2)/3
