Find the value of the following polynomial at the indicated value of the variable:
$p(t) = 5t^{2} - 11t + 7$ at $t = a$

(N/A) Given the polynomial $p(t) = 5t^{2} - 11t + 7$.
To find the value of the polynomial at $t = a$,substitute $a$ in place of $t$ in the given expression.
$p(a) = 5(a)^{2} - 11(a) + 7$
$p(a) = 5a^{2} - 11a + 7$
Therefore,the value of the polynomial $p(t)$ at $t = a$ is $5a^{2} - 11a + 7$.
