Y=-3/2x + 2 this is because of algebra
When you round you have to check the number to the right of the number you are rounding. If the number to the right is 0-4 then you keep the number the same. 5-9 the number you are rounding goes up by one. Now the 4 before the decimal point is in the ones spot. The 5 to the right of the 4 is the tenth spot and the 6 to the right of that is in the hundredth spot. so this is where we need to round. To the right of the 6 is a 4 so the number would stay the same. Now when you round you drop all the numbers after it so the number is 3184.56
Answer:
Step-by-step explanation:
The formula for arc length is:
Where Θ is measured in degrees.
We know that the arc length is 8π when the degree is 80. So, substitute 8π for A and 80 for Θ:
Divide both sides by 2π:
Simplify the fraction:
Multiply both sides by 9/2:
So, the radius is 18.
Now, we can find the area of the circle. The formula for the area of a circle is:
Substitute 18 into r:
Simplify:
And we're done!
It should be 3 but i think 4
YES if you simplify 15:10 by 5 since they can both be divided by 5 the ratio becomes 3:2
