Suppose an object starts moving at u and gains an acceleration of a. After time t, it gets a speed v after travelling a distance of s.
a = (v - u) / t => v - u = at
v = u + at
s = ut + 1/2(v - u) t
s = ut + 1/2 (at) t
s = ut + 1/2 at2
s = ut + 1/2 at2
v2 = (u + at)2
v2 =u2 + 2uat + a2t2
v2 = u2 + 2a (ut + 1/2 at2)
v2 = u2 + 2as
v2 = u2 + 2as
This is a trial and error answer.
Suppose that QT = -3, then
x + 2 = y
2x = y + 3
Apply substitution,
2x = (x+2) + 3
2x = x + 5
x = 5
y = 7
chek your answer,
x + 2 = y
<span>5 + 2 = 7</span>
Answer:
So if x= 1 , y= -20 , z = -5 , we just have to replace those values on the equation
Answer:
?
Step-by-step explanation:
I believe its 6047. But you could also round it to 6o.
