Answer:
a) decay
b) 2,950,000
c) 0.025
d) 
e) 2,409,123
Step-by-step explanation:
<u>Part (a)</u>
Exponential DECAY, since the population was decreasing annually.
<u>Part (b)</u>
Initial amount = 2,950,000 people (in the year 2000)
<u>Part (c)</u>
Decay factor = 2.5% = 0.025 (in decimal form)
<u>Part (d)</u>
General form of exponential decay function:
where:
- a = initial amount
- r = rate of decay (in decimal form)
- x = time (in years)
Given:
<u>Part (e)</u>
To determine the city's population in 2008:
Answer:
The slope is -0.048/2.000 or -0.024
Step-by-step explanation:
Answer:
1 ton = 2000 pounds
1 pound = 16 ounces
Step-by-step explanation:
You have a square with half circles along the sides.
The length of each side is 4ft, so the radius of the circles is 2ft
to calculate the perimeter you can calculate the circumference of 4 half circles = 2 complete circles
c=2r*
=
2*2
=12.56
perimeter=2c=25.12=8
the area is the area of 2 circles+the area of the square
circle area= r^2*
=2*2
=4
concrete area=circle area*2+square area
=4
*2+(4*4)
=8
+(4*4)
=8
+16ft
=41.12 ft^2
Hi there! :)
Answer:
(75x - 67y) - (47x + 15y)
Distribute the '-' sign with the terms inside of the parenthesis:
75x - 67y - (47x - (15y))
75x - 67y - 47x - 15y
Combine like terms:
28x - 82y
Distribute out the greatest common factor:
2(14x - 41y)
