Answer:
x = 21 units
Step-by-step explanation:
<em>The tangent squared is equal to the secant's total length multiplied by the secant's length without the part inside the circle.</em>
So here, that will look like: <em>36² = 27 * (27 + x)</em>
Expansion and multiplication gives us: <em>1296 = 729 + 27x</em>
Subtract from both sides: <em>567 = 27x</em>
Divide from both sides: x = 21.

Answer:
f(-4) = -120
Step-by-step explanation:
So we know that f(x) = 11x - 5x² + 4, and we are trying to solve for f(-4). To solve for f(-4), we plug -4 for x in the equation of f(x). In other words, change all x's into -4 in the equation 11x - 5x² + 4 and then solve.
f(x) = 11x - 5x² + 4
Plug in -4 for x.
f(-4) = 11(-4) - 5(-4)² +4
Simplify. 11(-4) = -44, 5(-4)² = 5(16) = 80.
f(-4) = -44 - 80 + 4
Solve.
f(-4) = -120
The answer is f(-4) = -120.
