Answer:
4.DH
Step-by-step explanation:
let's assume the point P to be the point that X will be after it is dilated.
we know that after dilation the length of PM should be two two times the length of XY
PM = 2.XY ===>
= 2
and from proportionality theorem we now that:
=
= 2
So we know XY should be half the size of MP and we can see the only line matching is DH thus the answer is DH
-20%
Basically, we are trying to find the change from 30 to 24 in terms of percent. We do this in three steps:
1) Find the difference between 30 and 24 as a number.
2) Divide the result from Step 1 by the starting number 30.
3) Multiply the result from Step 2 by 100 to get it in terms of percent.
The three steps above can be made into a formula. Thus, to find the percent change from 30 to 24, we use this formula:
((Y-X)/X)*100 = Percent Change
X is the starting number 30, and Y is the ending number 24 that it changed to. When we enter these numbers into the formula, we get:
((24-30)/30)*100 = -20.00%
Thus, the answer to the question "What is the Percent Change from 30 to 24?" is:
-20.00%
H^2 = B^2 + P^2
1. 12^2 = 6^2 + 9^2
144 = 36 + 81
144 = 117
Therefore, this is not a Pythagorean triple.
2. 12^2 = 10^2 + 7^2
144 = 100 + 49
144 = 149
Therefore, this is not a Pythagorean triple.
3. 25^2 = 18^2 + 16^2
625 = 324 + 256
625 = 580
Therefore, this is not a Pythagorean triple.
4. 45^2 = 36^2 + 27^2
2025 = 1296 + 729
2025 = 2025
Therefore, this is a Pythagorean triple.
The last one is a Pythagorean triple
Answer:
(0,0)
Step-by-step explanation:
the x coordinate for the vertex is at the line of symmetry
ax^2 +bx+c
the line of symmetry is at h =-b/2a
x^2 =12y
divide by 12
1/12 x^2 = y
a = 1/12 b=0 c=0
h = 0/(2* 1/12)
h =0
to find the y coordinate, substitute x=0 back in
y = 1/12 * 0 = 0
the vertex is (0,0)
