Answer:
7,228,202%
Step-by-step explanation:
Population at first census in 1979 was 3929
If the Population had increased to 284,000,000 by 2000, the population increase will be;
284,000,000-3929
= 283,996,071
%increase in population = increment/initial population×100%
= 283,996,071/3929×100%
= 7,228,202%
This means that the population has increased by 7,228,202%

Answer:
-5
Step-by-step explanation:
To Solve x we can use the product rule and multiply 4 in the the brackets:
We can move the fourty to the right hand side of the equal sign and then simplify the equation by dividing the whole expression by 8:
The value of x is -5
D: ( x, y ) ---> ( 4x, 4y )
A ( 2, 1 ), B ( 4, 1 ), C ( 4, -3 )
A. This is a dilation about (0, 0) with a scale factor of 0.25; A'(8, 4), B' (16, 4), C' (16, -12).
B. This is a dilation about (0, 0) with a scale factor of 4; A'(8, 4), B' (16, 4), C' (16, -12).
C. This is a dilation about (0, 0) with a scale factor of 0.25; A'(0.5, 0.25), B, (1, 0.25), C' (1, - 0.75).
D. This is a dilation about (0, 0) with a scale factor of 4; A'(0.5, 0.25), B'(1, 0.25), C'(1, -0.75)
The correct answer is:
B. This is a dilation about (0, 0) with a scale factor of 4; A'(8, 4), B' (16, 4), C' (16, -12).
Step-by-step explanation:
Given
Dilation: D : (x,y) => (4x,4y)
And Vertices
A ( 2, 1 ), B ( 4, 1 ), C ( 4, -3 )
Applying dilation on all vertices
To find the scale factor,
As we are multiplying each vertex coordinate by 4, the dilation factor is 4.
Moreover,
Hence the scale factor is 4.
So,
The correct answer is:
B. This is a dilation about (0, 0) with a scale factor of 4; A'(8, 4), B' (16, 4), C' (16, -12).

The distance of salmon from the surface of the water is 8 feet.
Calculate the answer using a math operator is referred to as a mathematical operation.
Basic mathematical operations are addition, multiplication, subtraction and division.
Given that,
The distance of school of salmon for the surface of the river = 5 feet.
Since, to escape a hungry bear, the school of salmon went down to 3 feet.
The position of the salmon to the surface = 5 + 3 = 8 feet.
The required distance of school of salmon from the surface of water is 8 feet.

Answer:
8 Feet below the surface
Step-by-step explanation:
If the salmon were initially 5 feet below the surface, and then travelled down an additional 3 feet from the initial 5, then the new position would be 8 feet down relative to the surface.
You can write this as -5 + -3 = -8, assuming that 0 represents surface level.
Cheers.
Hi there! :) The answer to your question is 4.02. I did 2.1+3.32= 5.42 then I did 5.42-1.4= 4.02. That I how I got the answer.
Hope I helped! ;D
