Answer:
t=1.283 seconds and
0.779 seconds
Step by step Explanation:
Given: h=18 ft
The given equation is h=2+33t-16t²
Then if we substitute the value of given h, h=18 ft into the given equation we have,
18=2+33t-16t²
Then if we re- arrange we have
16t²−33t+16=0
We can see that the above quadratic equation is in standard form, with a=16, b=33 and c=16 then we can use quadratic formula in solving it which is
t= −(−33±√[(−33) ²−4×16×16)]/(2×16)
= [33±√[1089−1024]/(32)
= [33±√[65]/(32)
=1.283 or 0.779 seconds
the two real roots , of the quadratic are:
1.283 and
0.779 seconds
t= 1.283 or 0.779 seconds
Hence, the ball is at 18 feet with height 0.779seconds after it has been thrown up and,
and is at 21 feet with height 1.283 seconds after after thrown down
Solve for Y
6x+12y=3
-6x+10y=-14
22y/22=-11/22
y=-1/2
Now solve for X
6x+12(1/2)=3
6x+6=3
6x/6=-3/6
x=-1/2
I hope it's the correct answer. Good Luck!

Let 
be the number of items produced and sold.
a) Cost function Fixed cost 
variable cost \times number of items
So,
b) Revenue Price of an item 
number of items
So,
c) Profit Revenue 
Cost
d) <u>Break even point</u> 
.
So, the product should be produced for 
or more items.
