Answer:
![A' =(-y,x)](https://tex.z-dn.net/?f=A%27%20%3D%28-y%2Cx%29)
Step-by-step explanation:
Given
Represent point A as thus;
![A = (x,y)](https://tex.z-dn.net/?f=A%20%3D%20%28x%2Cy%29)
Required
Determine the new position of A, when rotated counterclockwise
The new position will be denoted as A'
When a point is rotated counterclockwise, we start by switching the positions of x and y as follows:
![Pos = (y,x)](https://tex.z-dn.net/?f=Pos%20%3D%20%28y%2Cx%29)
Then, y is negated to give A'
![A' =(-y,x)](https://tex.z-dn.net/?f=A%27%20%3D%28-y%2Cx%29)
Answer: 6144m^2
Step-by-step explanation:
P(A) =0.54
P(B)= 0.68
P'(A)= 1-0.54 = 0.46
P'(B)= 1- 0.68 = 0.32
The probability of neither of both event will occur:
= P'(A)×P'(B)
=0.46 × 0.32
=0.1472
Answer:
Yes its correct

Hey there.. I will be more than happy to help you today.. :)
A Number squared decreased by ten
We will do this with steps:-
Step 1 - "A number ". So, Let's say any number be x
Step 2 - "A number squared". Our number x is squared i.e. x²
Step 3 - "A number squared" ( i.e. x² ) is decreased by ten
x² - 10
This is your answer.
Hope this helps you :)
