Answer: a 470
Step-by-step explanation:
The exponential growth equation with rate of growth r in time period t is given by :-
, where A is the initial amount
Given : The rate of growth of population every year : 0.9% =0.009
The initial population = 430
Then , the exponential growth equation in time period t is given by :-
In 2010 or for t= 10 years
The projected population of the town will be :-
Hence, the projected population of the town in 2010 is about 470.
Answer:
Step-by-step explanation:
In algebra , We use algebraic expression to represent word phrase.
For example : 7 is added to p is written as " "
-8 is multiplied by p is written as " "
The statement : Suzy found the difference of x and 4 and then divided by 2.
First we express the difference of x and 4 as
Then, we express entire statement : "difference of x and 4 and then divided by 2" =
Hence, the algebraic expression to represent this word phrase:
<em></em>
Solution
Step 1
Two distinct lines intersecting each other at 90° or at right angles are perpendicular to each other.
Hence apply this to question 8 the type of lines shown in the figure is perpendicular lines. Option C
Step 2
To explain this as stated above line A and line B intersect each other at a right angle hence line A and B are perpendicular lines. The line segments are seen below.
