Answer:
y = 5x -2
Step-by-step explanation:
The slope is given by the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (8 -3)/(2 -1) = 5
The y-intercept is given by the formula:
b = y -mx
b = 3 -5(1) = -2
Then the slope-intercept form equation is ...
y = mx +b
y = 5x -2 . . . . . . . . using the m and b we found above
Answer:
a)
b)
And we can use the quadratic formula to solve it:
And since the time can't be negative the correct option would be
Step-by-step explanation:
For this case we can use the following kinematics formulas:
For this case we assume that the only acceleration is the gravity a = g =9.8 m/s^2. And for this case we can assume that the reference point is and the final height would be since is below the initial point.
Teh acceleration would be a=-g, since the gravity is acting dowward, we assume that the initial velocity is 0, so then we have everything to replace and we got:
And solving for t we got:
For the second part assuming that We have an initial vertical speed of we have the following equation:
And we have this quadratic equation:
And we can use the quadratic formula to solve it:
And since the time can't be negative the correct option would be
