Answer:

t = [0.493,4.2]

Step-by-step explanation:

The height of the rocket straight up into the air is given by :

$h(t)=-16t^2+85t+5$

We need to find the interval the rocket be at least 43 feet above the ground.

$43\ge -16t^2+85t+5\\\\t\ge 0.493\ and\ t\le 4.82\ s$

So, the required interval during which the rocket is at least 43 feet above the ground is [0.493,4.2].

Sally is 1 year older than 3 times the age of joe.Chirs is 5 years younger than 6 times the age of joe.If sally and Chris are th

Sav [38]

S = sally C = Chris J = Joe
sally is one year older than 3 times the age of joe, so
s = 3j + 1
chris is 5 years younger than 6 times the age of jo, so
c = 6j - 5
sally and chris are the same age so
s = c so
3j + 1 = 6j - 5
-3j -3j
1 = 3j - 5
+5 +5
6 = 3j or
3j = 6
3j/3 = 6/3
j = 2

check
s = c
3(2) +1 = 6(2) - 5
6 + 1 = 12 - 5
