Answer:
D. Minimum at (3, 7)
Step-by-step explanation:
We can add and subtract the square of half the x-coefficient:
y = x^2 -6x +(-6/2)^2 +16 -(-6/2)^2
y = (x -3)^2 +7 . . . . . simplify to vertex form
Comparing this to the vertex for for vertex (h, k) ...
y = (x -h)^2 +k
We find the vertex to be ...
(3, 7) . . . . vertex
The coefficient of x^2 is positive (+1), so the parabola opens upward and the vertex is a minimum.
Answer: Car B traveled 60 mph.
Step-by-step explanation:
A= B-15
A: (B - 15)(2 hr)=D
B: (B)(1.5)=D
Since B and A traveled the same distance you can plug in 1.5B for D.
2B - 30 = 1.5B
-1.5B +30 = -1.5B
——————+30—
2(0.5B) = 2(30)
B = 60 mph
Answer:
Fr^2/Gm_2=m_1
Step-by-step explanation:
What you do first is you have to cross-multiply so f*r^2 and 1*gm_1m_2 to get
Fr^2=Gm_1m_2. Next you will divide Gm_2 from both sides to get
Fr^2/Gm_2=m_1 as your answer.
Answer: 2075
Step-by-step explanation:
Sonia traveled 2905 miles in 7 days
2905/7=415 miles/day
415*5=2075 miles
The answer is A because if u shift 4 units up then it's +4
