AB = 14
The angle = 39 degrees
The slope of a line that is parallel to y=5x+3 is 5x.
Two lines must have the same slope to be parallel to each other.
Well for 3. you use the Pythagorean theorem to say that 28^2 - 18^2= x^2 so 21.4 and for 4. the Pythagorean theorem says a^2 + b^2 = c^2 with c being the hypotenuse of any right triangle so the sums of the two smaller squares make the sum of the larger square making the answer b
Answer:
it is a parabola with max of -4
so domain (-∞,∞)
