Not A C or E So maybe B or D hope this helped a little
If the coefficient squared is greater than one (multiplication), it stretches the graph vertically by the factor of the coefficient.
If the coefficient squared is less than one (division), it compresses the graph vertically by the factor of the coefficient.
Answer:
d
Step-by-step explanation:
Try this solution:
Common view of the equation of the circle is (x-a)²+(y-b)²=r², where point (a;b) is centre of the circle, r - radius.
1. using the coordinates of the centre and point (2;13) it is possible to define the radius of the circle: r=√(5²+12²)=13;
the equation is (x+3)²+(y-1)²=13² or (x+3)²+(y-1)²=169;
2. using the coordinates of the centre and the radius: (x-2)²+(y-4)²=6² or (x-2)²+(y-4)²=36.
Answer:
The ratio between them is approximately 
, therefore the correct answer is A.
Step-by-step explanation:
In order to calculate the ratio of the diameter of the Sun to the diameter of the Earth we will first represent the Earth's diameter as a scientific notation, to do this we will add one to the power of ten for every time the comma walks to the left until there's only one number to the left. This is done to make the division easier,
The ratio is given by the Sun's diameter divided by the Earth's, as shown below:
The ratio between them is approximately , therefore the correct answer is A.
