Answer:
9.577 mm.
Step-by-step explanation:
We have been given that the diameter of a quarter is 24.26 mm and the diameter of a nickel is 21.21 mm.
Let us find the circumference of quarter and nickel using circumference of circle formula.
, where r represents radius of the circle.
Since we know that diameter of circle is 2 times its radius, so let us find radius of quarter and nickel by dividing their diameter by 2.






Therefore, circumference of quarter is 76.1764 mm.
Let us find circumference of nickel.

Let us subtract circumference of nickel from circumference of quarter.


Therefore, the distance around a quarter is 9.577 millimeters bigger than a nickel.
Answer:
1st blank: X axis reflection
2nd blank: Y axis reflection
Step-by-step explanation:
If you drew the first triangle and then the second triangle on a piece of paper, you would notice that it would reflect across the corresponding axis.
So the solution is to just draw it out.
Answer:

Step-by-step explanation:
We want to find the inverse of

We interchange x and y.

We need to solve for y, so let us multiply through by 2.

Subtract 6 from both sides.

Therefore the required inverse is
