1) 30x4 − 20x3 + 15x2

This is the answer to 1. Don't forget to rearrange the terms in ascending order. That can trip people up.

2) x3 + 8x2 + 13

Don't forget to check the terms sign. The subtraction symbol switches them all.

SS tax is 6.2% of 1,047.30

In math "of" means times, so

.062 x 1047.30 = 64.9326

Rounded to the nearest cent $64.93

A grasshopper jumps from the ground. The path of the grasshopper is modeled by the equation y=−0.5x2+8x where x is the horizonta

Marysya12 [62]

Please use " ^ " to indicate exponentiation: 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 = −0.5*8^2+8(8) = -0.5(64) + 64, or 32 units.
