Answer:
Therefore,
The ball strike the ground at time , t = 6 s
Step-by-step explanation:
Given:
The equation for the ball’s height, h, at time t seconds is
To Find:
time, t = ? (When the ball strike the ground)
Solution:
When the ball strike the ground height, h will be ZERO,
So put h = 0 in above given equation for time,
Which is a Quadratic Equation
Dividing throughout by - 4.9 we get
On Factorizing, splitting the middle term we get
As time cannot be negative,
t = 6 s
Therefore,
The ball strike the ground at time , t = 6 s
Answer:
Hi there, you can use Pitagoras relationship to solve this up (Without using any other "tool".
Point A is located wheter in (-6,8) or could be located in (-6,8)
Step-by-step explanation:
Point A is 10 units away from the origin, and its x coordinate is -6, using this information, you can draw a triangle from 0 to -6 (the basis) and using 10 as the hypotenuse, so, you have this equation:
solving for Y variable, you have this
y=±
Note the combined sing ±, meaning that y=8 is a valid answer and that y= -8 is also a valid answer.
Hope It helps
