The simple way to dilate from the origin is to multiply each coordinate by the dilation factor.
Example:
point A(2,-4) dilated by 2
A'(2*2, -4*2) = A'(4, -8)
Point A dilated by 1/2
A''(2*1/2, -4*1/2) = A''(1, -2)
If you have multiple points dilated by the same factor, then follow the procedure for ALL the points
The answer is 3.00-0.22=2.78
Answer:
paul put it at 3,8 and its supposed to be at 0,6
Step-by-step explanation:
Explanation:
We can rewrite the expression:
√8×√20
using the following rule for radicals:
√a⋅√b=√a⋅b
√8⋅√20⇒√8⋅20⇒√160
Now, we can use this rule for radicals to simplify the radical:
√a⋅b=√a⋅√b
√160⇒√16⋅10⇒√16⋅√10⇒4√10
So each digits can only be selected once.
Let's start counting desired outcome.
Hundred position need to be at least 8. There is only one possible digits. So we will go with 8 and then there are 7 remaining digits.
One position can only be 2,4,6. because we need number to be even. So that's 3 possible digits. We will take one. 6 digits remaining.
Ten position can be anything so that would be 6 possible digits.
So the number of desired outcomes is 3·6 = 18.
Now count all outcomes.
Hundred, ten, and one position can get any digits
So that's 8·7·6 = 336
So the probability would be 18 / 336 = 3 / 56 ≈ 0.0536
Hope this helps.
