Answer:
pi times 4
Step-by-step explanation:
Circumference: pi times diameter (pi)(d) or pi times 2 times the radius (pi)(2r)
From the information: v is 64 while c is 5
Differentiate the new equation h=-16
+ 64t + 5 to get 
= -32t + 64.
no 13). At maximum height this derivative equals zero so: -32t + 64 = 0; -32t = -64; t=2.Hence ans is 2 secs
no 14). put t as 2 sec in the equation: h=-16 + 64t + 5. This gives
h=-16( 
) + 64(2) + 5; h=-64+128+5=69. Hence h is 69ft
Answer
Everything will increase.
Step-by-step explanation:
According to the question, the chair rises every 4 seconds 14 feet high. Therefore, the relationship between the chair and time is: the chair rises every 4 seconds.
Feel free to copy it I don't mind :)
The answer would be a -3/4 I’m almost positive
