Answer:
Step-by-step explanation:
To find out if a point (x, y) is on the graph of a line, we plug in the values and see if we get a true statement, such as 10 = 10.
<span>It is estimated that the city of Houston, Texas, will double in size every 35 years:
</span>P=Po(2)^(t/35)
<span>If the population is currently 2.4 million people:
Po=2.4 millions
</span><span>How many people will there be in 20 years?
t=20 years, P=?
P=(2.4 millions)(2)^(t/35)
P=(2.4 millions)(2)^(20/35)
P=(2.4 millions)(2)^(0.571428571)
P=(2.4 millions)(1.485994289)
P=3.566386294 millions
P=3.6 millions
Answer: There will be 3.6 million people in 20 years.</span>

Answer:
100 units
Step-by-step explanation:
We want to find x when ...
C = 11030
x² +10x +30 = 11030 . . . . fill in for C
x² +10x = 11000 . . . . . . . . subtract 30
x² +10x +25 = 11025 . . . . add 25 to complete the square
(x +5)² = 105² . . . . . write as squares
x +5 = ±105 . . . . . . . take the square root
x = -5 ±105 = {-110, 100}
The number of units manufactured at a cost of $11,030 is 100.
