Because this is a positive parabola, it opens upwards, like a cup, and the vertex dictates what the minimum value of the function is. In order to determine the vertex, I recommend completing the square. Do that by first setting the function equal to 0 and then moving the 9 to the other side by subtraction. So far:

. Now, to complete the square, take half the linear term, square it, and add that number to both sides. Our linear term is 6. Half of 6 is 3 and 3 squared is 9. So add 9 to both sides.

. The right side reduces to 0, and the left side simplifies to the perfect square binomial we created while completing this process.

. Move the 0 back over and the vertex is clear now. It is (-3, 0). Therefore, 0 is the minimum point on your graph. The first choice above is the one you want.

Step-by-step explanation:
√576 = √64*9 = √(2)⁶*(3)² = 2³*3 = 24
√15876 = √4*81*49 = √2²*3⁴*7² = 2*3²*7 = 126
Answer:120°
Step-by-step explanation:
sum of exterior angles=360
In a triangle we have 3 exterior angles
Size for each exterior angle=360/3
Size for each exterior angle=120°
Answer:
drone is 60km/h bird 40km/h
Step-by-step explanation:
Graph the line using the slope and y-intercept, or two points.
Slope= -5
y- intercept= (0,2)
The answer has two points (0,2) and (1,-3) place them and then make a line going left through them.
