Given:
Population of a colony in 2000 = 250
Population of a colony in 2004 = 400
To find:
The average rate of change.
Solution:
Let y be the population of the colony at x year.
The population of a colony grows from 250 in the year 2000 to 400 in the year 2004. So, the two points are (2000,250) and (2004,400).
Formula for slope or average rate of change is




Therefore, the average rate of change of population is 37.5.
I think the rest of the question is ( what is the price after the discount)
the new price will be = ( c - 0.05 *c )
Answer:
The distance between zoo and library is 200 feet....
Step-by-step explanation:
Look at the picture. As the figure describes,
Let H denote the position of Helicopter.
Z denote the position of Zoo.
and L denote the position of library.
Hence, we will firstly find the distance between G and zoo and then we find the distance between G and library and subtract the first distance from second to obtain the distance between zoo and library.
In ΔHGZ.
tan 60°=HG/GZ
√3=100√3/GZ
Hence, GZ=100 feet.
Similarly in ΔHGL
tan 30°=HG/GL
1/√3=100√3/GL
GL=300 feet.
Hence, the distance between zoo and library is:
GL-GZ
=300-100
=200 feet.
Hence, the distance between zoo and library is 200 feet....
Answer:
Square B 9 × 7.5
Step-by-step explanation:
The computation is shown below:
9 × 7 = 63 > 55
8 × 5 = 40 < 55
5 × 10 = 50 < 55
As it can be seen that in only one condition the total of square feet is less and in the other conditions the total of square feet is more
Therefore the option Square B is correct
And, the rest of the options are incorrect
The same to be considered
Answer:
-51
Step-by-step explanation:
Let's do order of operations.
10+8-70-(-1) <- We did negative 7 times 10.
18-70-(-1) <- We did 10 plus 18.
-52-(-1) <- We did 18 minus 70
When you open the () we get:
-52--1
Negative minus a negative equals a positive.
-52+1=
-51
