Answer:
You subtract Sean's mothers time from the lowest score of the women's winner age 65-69 group.
You will notice the winner of the 65=69 group is a higher value from the two but a lower value in the actual 65-69 group. Once you find that lower value you then subtract Sean's Mothers result, show the answer in difference of; time difference in seconds or minutes/seconds.
Step-by-step explanation:
Y=-0.5x²+1.25
To find the vertex we need to write given equation in the vertex form.
y=a(x-h)²+k
(h,k) - coordinates of the vertex
y=-0.5x²+1.25 can be written as
y=-0.5(x-0)²+1.25
So, h=0, k=1.25
Vertex is (0, 1.25)
Complementary angles are angles that add up to 90 degrees. 2x is the first angle. Let y be the second one.
y+2x = 90
Subtract 2x from both sides.
y = 90 - 2x.
The second option is your answer. Have is nice day! :)
Answer:
4π in ≈ 12.57 in
Step-by-step explanation:
One full revolution (2π radians) is made in 60 minutes. In 40 minutes, the hand moves through an angle θ of (40/60)(2π) = 4π/3 radians. The length of the arc is ...
s = rθ = (3 in)(4π/3) = 4π in ≈ 12.57 in
