Answer:
Find out the what function equation represents the population of the city after t years .
To prove
The population of a city is 451,400. The population is expected to decrease at a rate of 3.2% each year.
This can be represented by exponential decreasing function.
Where a is the initial value.
r is the rate in decimal form
t is the time.
Here
a = 451,400
3.2 % is written in the decimal form.
= 0.032
Put in the formula
Therefore the decrease in the population of the city after t years is represented by
I suspect this is what you mean, if let me know
2x(3)^2+x(2)^2
2(3)(9)+3(4)
54+12=66
6x-18 14x+38
subtract the 6 from the 6 and the 14 which will give you: then add the 18 to the the 18 and the 38
8x = 56
then divide 8/8 which is zero and 8/56 which equals 7 so ur answer is x=7
Answer: C
Step-by-step explanation:
4x + 1 = 9
4x + 1 -1 = 9-1
4x=8
8/4=2
Answer:
u=30
x=150
z=150
y=30
Step-by-step explanation:
u=y [ being vertically opposite angle]
x+u=180[ being linear pair]
x+30=180
x=180-30
x=150
z=x[being vertically opposite angle]
z=150
y=u[ being voa]
