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.
You did not supply instructions for this problem.
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:
400 degrees
Step-by-step explanation:
Step 1 : To convert radians to degrees, multiply the given radian by 180/pi
7pi/3 x 180/pi
Step 2 : Cancel pi
7/3 x 180
= 420 degrees
Step 3 : Round it to nearest 100
Since 20 is closer to 400 than 500 therefore it will be rounded off to
400 degrees
!!
Y=v(initial)*t+1/2at^2
since the velocity is zero at the maximum height then we get
y=1/2at^2
a is just acceleration due to gravity so a=g which is 9.8 m/s^2.
so y=1/2gt^2.
