The rate of change is 2om per hour
Answer:
27.7 degrees
Step-by-step explanation:
We can use the inverse sine to find the angle x as we are given the opposite sided length and the hypotenuse
x = sin-1(13/28)
x = 27.66
x = 27.7 (round to tenths)
Convert the 5 6/8 into a fraction
46/8
3/8+46/8=49/8
or
6 1/8
Given the triangles ABC and EDC
We will find the transformation that makes the triangles are similar
As shown: the triangles are reflected over the y-axis
the rule of the reflection over the y-axis will be as follows:

And as shown, the length of the side AB = 3 units
And the length of the side ED = 1 units
So,

So, the answer will be:
D) (x,y) ⇒ (-x, y)
E) (x,y) ⇒ (1/3 x, 1/3 y)
