# Chapter 5 - Section 5.3 - Polynomials and Polynomial Functions - Exercise Set: 84a

910 feet

#### Work Step by Step

We are given that the height of the football above the Colorado River at any time t can be described by the polynomial function $P(t)=-16t^{2}+10t+910$. In order to find the height at $t=0$ seconds, we can calculate the value of $P(0)$. $P(0)=-16(0)^{2}+10(0)+910=0+0+910$ feet
