Answer:
A Walk in the City
Make a list of the number of cars, jeeps, tricycle, and even trucks you've seen on your way to school. On a Decision Making Chart, answer the question, "Does the volume of traffic affect the air quality in my local community?" Write your reasons for saying YES on the Reasons for column, and the reasons for saying NO on the Reasons Against column. At the bottom of a chart, make a position by writing your decision on the same question.

Answer:
We readily separate the variables and integrate:
∫dP/P=∫(k+bcos2t)dt
ln P=kt+(b/2)*sin2t+ln C
Clearly C = Po, so we find that P(t) = Poexp(kt + (b/2)* sin 2t). The 271- curve with the typical numerical values P_o = 100, k = 0.03, and b = 0.06. It oscillates about the curve which represents natural growth with P_o and k = 0.03. We see that the two agree at the end of each full year.
note:
find the attached graph
BE = 3x - 1
BC = BD - CD = 2x - 4 - 2
DE = CE - CD = 2x - 3 - 2
_______________________
BC + CD + DE = BE
( 2x - 4 - 2 ) + 2 + ( 2x - 3 - 2 ) = 3x - 1
2x - 6 + 2 + 2x - 5 = 3x - 1
2x + 2x - 5 - 6 + 2 = 3x - 1
4x - 11 + 2 = 3x - 1
4x - 9 = 3x - 1
Add both sides 9
4x - 9 + 9 = 3x - 1 + 9
4x = 3x + 8
Subtract both sides 3x
4x - 3x = 3x - 3x + 8
<em>x = 8 </em>
___________________
BD = 2x - 4
BD = 2(<em>8</em><em> </em>) - 4
BD = 16 - 4
BD = 12
And we're done...
The graph shows the relationship between the total cost. The true statement is
Seven erasers cost $3.50. Option D
This is further explained below.
<h3>The graph shows the relationship between the total cost and the number of erasers bought at the student store. Which statement is true?</h3>
Generally, A cost is the worth of the money that has been spent in the process of producing something or delivering a service, and as a result, it is no longer accessible for use.
This concept is utilized in manufacturing, research, retail, and accounting. In the world of business, a cost may refer to a purchase, in which case the sum of money spent on the item in question is considered to be the cost of the item.
In conclusion, each eraser will cost u 50 cents
so 7 erasers will cost (7 * 0.50) = 3.50
