slope (y2-y1)/(x2-x1)
m=(10000-4000)/(0-15)
m=6000/-15
m=-400
the helicopter descends 400 ft/min
Choice B
We are given the two sides of the right triangle therefore we can use the pythagorean theorem to solve for the third side. This theorem states that, in a right triangle the square of the hypotenuse is equal to the sum of the square of each leg.
c² = a² + b²
70² = 35² + b²
b = √70² - 35²
b = 60.62 feet
That is the difference of two squares and is factored in this way:
(7 +x) * (7 -x)
Answer:
B
Step-by-step explanation:
The dot on 2 is an open spot, so 2 isn't part of the solution. the arrow points towards +∞ so, yeah. b
