The tangent secant theorem says
PR × PS = PQ²
4 × (4+5) = PQ²
36 = PQ²
PQ=6
Answer: 6
<span>Rational exponent are exponents written in the form of a fraction.
A rational power can be rewritten as a radical in the following way: the bottom of the rational exponent is the root, while the top of the rational exponent is the new exponent on the radical.
Example: X^(1/2)= </span>√X
Simple interest: i = p*r*t, where r is the annual interest rate and t is the number of years.
14%
This boils down to ----------- interest per month: a monthly rate of 0.0117.
12 mo
Thus, after 3 months, the amount owed, including the original $700, would be $700 + 3($700)(0.0117) = $724.57.
It would be 9x^3+6x^2+12x+8
