Answer:
h(3.2) represents the height of the rock 3.2 seconds after it is propelled. Remember, h(t) represents the height of a rock t seconds <em>after it is propelled.</em>
Answer:
<h2>6.5</h2>
Step-by-step explanation:
Given the sum of the series represented as 
. <u>To get the sum to infinity of the geometric series, we need to get its first term and its common ratio</u>. comparing to the general term of the sum of series of a GP 
a = first term of the series
r = common ratio
On comparing to the given series, a = 1.3 and r = 0.8
Sum to infinity of a Geometric series is expressed as:
The left triangle is a 30-60-90 triangle so line ST = 2 which means line RT is 4 (double the length of ST).
The right triangle is a 45-45-90 triangle which means RT and RQ are congruent.
So if RT = RQ and RT = 4, then x = 4
7x+10y=6400
x+y=700
x=700-y
7(700-y)+10y=6400
4900-7y+10y=6400
-7y+10y=1500
3y=1500
y=500
x=700-y
x=700-500
x=200
there were 200 children and 500 adults at the show
