-2/1 I did this is math class , we’re on this unit to,
Explanation
Saying it’s a negative number because it is pointing in a left word position, you have to go down twice and over once to find the exact point where the line crosses over a point on the graph, and there you will get -2/1
Answer:
0.72secs
Step-by-step explanation:
Given the height of the ball in air modeled by the equation:
h=−16t²+23t+4
Required
Total time it spent in the air
To get this we need to calculate its time at the maximum height
At the maximum height,
v = dh/dt = 0
-32t + 23 = 0
-32t = -23
t = 23/32
t = 0.72secs
<em>Hence the total time it spend in the air will be 0.72secs</em>
It will take Jon 240 minutes or 4 hours.
I got this:
Tennis court is a rectangle
(Rectangle - 2 sides the same length and the other 2 sides the same. So 2 pairs of equal length sides)
If one is 27 the other has got to be 27 as well - 27+27= 54
210 - 54 = 156
156 / 2 = the other "pair"
Hope that helps and correct me if I'm wrong!
