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>

Which expression represents the second partial sum for
NeTakaya

Answer:

S_{2} = 3\cdot \left(\frac{1}{2} \right)^{0} + 3\cdot \left(\frac{1}{2} \right)^{1}

Step-by-step explanation:

The first partial sum is:

S_{1} = 3\cdot \left(\frac{1}{2} \right)^{0}

The second partial sum is:

S_{2} = 3\cdot \left(\frac{1}{2} \right)^{0} + 3\cdot \left(\frac{1}{2} \right)^{1}

Which represents the option A.
