Answer:
15 m/s
Step-by-step explanation:
Velocity is the derivative of position:
v(t) = s'(t) = 24 +6t -3t^2
v(3) = 24 +3(6 -3·3) = 15
At t=3 seconds, the velocity of the body is 15 m/s.
4n + 2n = 4
6n = 4
Divide by 6 both sides
n = 2/3
A)
The slope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
We have the points (2, 5.1) and (-1, -0.5). Substitute:
Therefore we have:
Put the coordinates of the point (-1, -0.5) ot the equation:
<em>multiply both sides by 2</em>
<em>add to both sides</em>
<em>divide both sides by 2</em>
Answer:
-------------------------------------------------------------------------
B)
We have the points (-2, 3) and (3, -4).
Calculate the slope:
Therefore we have:
Put the coordinates of the point (-2, 3) to the equation of a line:
<em>subtract from both sides</em>
Answer:
Well, the exact product of the two is 3,024, so that would mean it's in between the numbers 3,023 and 3,025.
I hope this helped! :)
