Answer:
40.5 ft
Step-by-step explanation:
Solve for the time at which the balls meet, then find the corresponding height.
__
The balls will meet at the height such that the two values of h are the same.
-16t^2 +56t = h = -16t^2 +156t -248
0 = 100t -248
t = 2.48
Using the first equation to find h, we have ...
h = t(-16t +56) = 2.48(-16·2.48 +56) = 40.4736
The balls meet at a height of about 40.5 feet.
Okay I'm not too sure on this but I believe it is the third one.
I hope this helps!!
Answer:
One
Step-by-step explanation:
The most triangles you can make from three given sides is <em>one</em>.
However, you may not be able to make any.
To form a triangle, the sum of the two smaller sides must be <em>greater than</em> the longest side.
16 + 11 > 26, so you can form one triangle: an obtuse scalene triangle.
