Solve y=-16(.72)^2+80sin80(.72)+0

$$y = - 16 ( .72 ) ^ { 2 } + 80 \sin 80 ( .72 ) + 0$$

Solve for y

$$y=59.2518340401612$$

Steps for Solving Linear Equation

Evaluate trigonometric functions in the problem

$$y = -16 {(.72)} ^ {2} + 80 \cdot 0.844327925502015 + 0$$

Calculate 0.72 to the power of 2 and get 0.5184.

$$y=-16\times 0.5184+80\times 0.844327925502015+0$$

Multiply -16 and 0.5184 to get -8.2944.

$$y=-8.2944+80\times 0.844327925502015+0$$

Multiply 80 and 0.844327925502015 to get 67.5462340401612.

$$y=-8.2944+67.5462340401612+0$$

Add -8.2944 and 67.5462340401612 to get 59.2518340401612.

$$y=59.2518340401612+0$$

Add 59.2518340401612 and 0 to get 59.2518340401612.

$$y=59.2518340401612$$

Assign y

$$y≔59.2518340401612$$
