Answer:
A
Step-by-step explanation:
1*1/4 is One lap, but you want 23 laps so exchange the 1 with a 23:
23*1/4
A
Answer: t= 4 seconds
Maximum height = 256 feet
Step-by-step explanation:
The height of the object projected upwards after t seconds is given by
s(t)=-16t^2+128t.
The expression is a quadratic equation. When this equation is plotted on a graph, height against time, it takes the shape of a parabola whose vertex represents the maximum height attained by the object.
To get the value of t at the maximum height,
t = -b/2a
From the equation,
a = -16
b = 128
t = -128/-2×-16
= -128 /- 32= 4
it will take 4 seconds to reach its maximum height
To find maximum height attained, put t= 4 in the equation
s(t)=-16t^2+128t
S = -16× 4^2 + 128×4
S = -256+512
S = 256 feet
Answer:
-3 1/2 + ( -6 1/2) = -10
5/8 - {-2/8} = 7/8
- 9/10 - 2/5 = -4
6 3/5 - (-2 1/5) = 44/5
Step-by-step explanation:
-3 1/2 + ( -6 1/2) = <em>-7/2 + (-13/2) = -20/2 =</em><em><u> </u></em><em><u>-10</u></em>
5/8 - {-2/8} = <em>5/8 + 2/8 = </em><u><em>7/8</em></u>
- 9/10 - 2/5 = <em>-18-2/5 = -20/5 = </em><u><em>-4</em></u>
6 3/5 - (-2 1/5) = <em>33/5 + 11/5 = </em><em><u>44/5</u></em>
Yes there is rotational symmetry and you can rotate 5 times in a complete circle.
so 360/5 = 72 degrees or C
