Answer:
A'(7, - 3 )
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
A(- 7, 3 ) → (- 7, - 3 )
Under a reflection in the y- axis
a point (x, y ) → (- x, y ), thus
(- 7, - 3 ) → A'(7, - 3 )

Answer:
In similar figures, the angles are congruent, even if the sides are not. Notice that one angle in each pair of figures corresponds to an angle in the other figure. They have the same shape but not the same size
Answer:
Step-by-step explanation:
Given the differential (d/dx)(cos−1(x)), to find the equivalent formula we will differentiate the inverse function using chain rule as shown below;
let;
Therefore;
Since x = cos y from the above substitute;
Hence, gives the required proof
The greatest common divisor of these numbers is 12.
