Answer:
96 ft
Step-by-step explanation:
Perimeter= a (base)+b (side)+c (side)
281 = 89 +b + c
281 -89 = b + c
192 = b+ c ( however in an iscoceles triangle, 2 sides aree equal therefore b and c will be equal)
So: 192/2 = 96
You have to be more specific, you should add a picture of your problem that’s your struggling with
Step-by-step explanation:
The height of the swipe card is given by :
.....(1)
We need to find the maximum height of the swipe card and the time to reach the maximum height.
For maximum height, put dh/dt = 0
So,

It will take 1.67 seconds to reach the maximum height.
Now, put t = 1.67 s in equation (1).

Hence, the maximum height of the swipe card is 34.68 feet and the time to reach this height is 1.67 s.
