Me with problem 3 letters a and b too

a) 30

b) 2

at 2 seconds, the balloon reaches the greatest height, 30

Step-by-step explanation:

y=height

x=seconds

The greatest height that the table shows is 30; the number of seconds it took to reach 30 is 2, (2,30)

Accordingly:

at 2 seconds, the balloon reaches the greatest height, 30

Pls let me know if this helps!

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
