Answer:
4 mi/h
Step-by-step explanation:
The distance between the cyclists is the hypotenuse of an isosceles right triangle. The hypotenuse is √2 times the length of the legs in such a triangle, so each cyclist must have ridden 8 miles in 2 hours.
Their speed is (8 mi)/(2 h) = 4 mi/h.

<em>Additional comment</em>
Consider an isosceles right triangle with leg lengths 1. Then the Pythagorean theorem tells us the length of the hypotenuse is ...
c² = a² +b² . . . square of hypotenuse is sum of squares of legs
c² = 1² +1² . . . . both legs are 1 in our example triangle
c² = 2
c = √2
That is, the hypotenuse is √2 times the leg length.
F(x): slope is 1.5
Y intercept is 1
G(x): slope is 2
Y intercept is 1
Statement A is correct
f(x) slope is less than g(x)
The y intercept of f(x) is the equal to the y intercept of g(x)
Answer:
$2.69
Step-by-step explanation:
Distribution method:
.20(2.50, 4.95, 6.00)
(0.50, 0.99, 1.20)
Now add them up.
Non-distribution method:
$2.50 x .20 = 0.50
$4.95 x .20 = 0.99
$6.00 x .20 = 1.20
Add them up
