Answer:
((2a+b)/2 , a/2)
Step-by-step explanation:
The midpoint is the mean/average of both the x and y values.
Our x values are a+b and a
Our y values are a-b and b
The midpoint x value is (a+b + a ) /2 = (2a + b)/2
The midpoint y value is (a-b + b) /2 = (a)/2
The midpoint combines these two values to get ((2a+b)/2 , a/2) as our midpoint
6 sec can take penny to strike the ground.
Solution:
Given data:

Re-arrange the terms from greatest degree to smallest degree.

We can solve it by applying quadratic formula,

Here a = –16, b = 48, c = 288




Now, write find two t's using plus and minus operation.


t = –3 (or) t = 6
We cannot write time is negative. so neglect t = –3.
Therefore t = 6.
Hence 6 sec can take penny to strike the ground.
What equation? You would have to pass a photo, but...
Standard form is: ax+by=c
Slope intercept form is: y=my+b
Point slope for is: y − y1 = m(x − x1)
