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:
B. 9.6 %.
Step-by-step explanation:
A = P e^rt
His investment doubles so it comes to 3000 * 2 = $6000.
Substituting in the formula>
6000 = 3000e^7.2r ehere r is the interest rate.
e^7.2r = 2
Taking logs
7.2r = ln 2
r = ln2 / 7.2
r = 0.096
So the rate is 9.6%.
75.4
12 would be considered the radius
C = 2 pi R
so just insert that into the formula and the answer should be
75.39 but if you round up it would be 75.4
Step-by-step explanation:
8/3 cups of sugar is needed to make 16 cookies.
For 90 cookies, we will need 8/3 * 90/16 = 15 cups of sugar.
