Answer:
We can prove the similarity of two circles by mapping one circle onto the other (i.e. making a circle look exactly like the other one) by a translation and a scale factor.
Let's map circle Y onto circle X for example. We need to make sure we have the same radii for both circles, so let's expand circle Y by a scale factor of 2. Then shift circle Y 6 units up and 6 units to the left to move the center point of circle Y over to that of circle X.
Now, since we could map circle Y onto circle X using transformations (scaling and translation), we know that the two circles are similar.
Answer:
three out of 10
Step-by-step explanation:
If the first ball drawn is purple, there will be eight purple balls left in the bag. Therefore, the probability the second ball will be purple is three out of 10.
Method for SA of cylinder=
2 x pi x r x h + 2 x pi x r^2
SA = 2 x pi x 4 x 10 + 2 x pi x 4^2
= 351.9 cm^2
Hope this helps!!
Answer:
1a the square root of 37
1b the same as a
2 y=3x+2
Step-by-step explanation:
a and b use the distance formula
for number 2 use rise over run to find the slope and find where the line intersects to find the y intercept.
Hope this helps :)
