Answer:
(x, y) ⇒ (x -2, y +2)
Step-by-step explanation:
Reflection across the line y = x+2 has the effect of interchanging x and y and translating by (-2, 2).
Reflection across the line y = x+4 has the effect of interchanging x and y and translating by (-4, 4).
The composition of these transformations is then ...
(x, y) ⇒ ((x +2) -4, (y -2) +4) = (x -2, y +2)
distance = rate * time
rate = distance / time
rate = .75 miles / .666666 hours
rate = 1.125 miles per hours (.125 = (1/8) ) so
rate = 1 plus 1/8 miles per hour. answer is B
Answer:
-1?
Step-by-step explanation:
That would be 644.8 / 31 = 20.8 feet / second
Answer:
See explanation
Step-by-step explanation:
The given trigonometric equation is 
.
We take the inverse cosine of both sides to get:
to the nearest degree
None of the options satisfies the given equation.
But if the question is actually;
Then;
.

.
Or
.
In this case the answer will be B
