How far is a football kicked if its y=-0.03x^2+1.53x

weqwewe [10]

The answer is 51 (not sure of the measurement unit). Assuming you mean the football hits the ground when it's kicked and lands somewhere downfield, y would be 0 (y means height from the ground, and if something is on the ground, it has no height. Hence, the 0). Set the equation equal to 0 and factor to solve for x. 0 = -.03x(x-51). 0 = -.03x and x = 0, or 0 = x-51 and x = 51

Find the area of a pentagon with an apothem of 7 centimeters

Alexeev081 [22]

If the side length of the pentagon is 19.27 centimeters. Then the area of the pentagon will be 337.225 square cm.

<h3>What is a polygon?</h3>

The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.

The apothem of the pentagon is 7 cm.

Then the area of the pentagon will be

$\rm Area = 5 \times \dfrac{1}{2} \times apothem \times side \ length$
