Domain is: -∞, ∞
Range is: 16, -∞
The answer is D-16
16/4= 4. 4x3=12. 12-2=10
I believe that the answer is c but if you wanted to make sure you could figure out the correlation on a graphing calculator.
Step-by-step explanation:
Axis of symmetry for quadratic ax² + bx² + c:
x = -b/2a.
Therefore for y = x² - 4x + 2,
-b/2a = -(-4)/2(1) = 2
The axis of symmetry is x = 2.
okay realize that the distance traveled by the small plane, distance traveled by jet, and the distance between them makes a right triangle. Using Pythagorean theorem and allowing x be the distance between them, x² = (20 miles)² + (64.5 miles
x = 67.53 miles the distance between the two entities in nearest tenth is approximately 67.5 miles.
