Please use " ^ " to indicate exponentiation: <span>y=−0.5x^2+8x
Examining this function, we see that its graph is a vertical parabola opening down.

However, one could guess that you might want to find the highest point of the grasshopper's path. To do this, find the vertex: Find the x value defined by
x = -b/(2a). Here, a= -0.5 and b= 8. Thus, the vertex is at x = -8/(2[-0.5]), or
x -8/(-1) = 8 units. The corresponding y value is then
y = </span><span>−0.5*8^2+8(8) = -0.5(64) + 64, or 32 units.</span>
Answer:
x = 65 + -2y

You should have specified that this is simple interest.
I=P(r/12)t
r=(12I)/(Pt)
r=(12(40))/(500(16))
r=0.06
r=6%

Answer:
○ sin 15° = sin 30°⁄2 = ±√[1 - cos 30°\2]
Step-by-step explanation:
According to the Sine Half-Angle Identity, this is the formula:
sin x = sin ˣ⁄2 = ±√[1 - cos x\2]
Notice the <em>-</em><em>cos</em><em> </em><em>x</em><em>\</em><em>2</em><em> </em>inside the radical. The second option nearly resembles this option. It has a positive symbol inside. Do not let this confuse you. The Cosine Half-Angle Identity is the formula that has a positive in the radical:
cos x = cos ˣ⁄2 = ±√[1 + cos 30°\2]
