Answer:
The focus of a parabola is (2, 5) and the directrix is y = 3. Find the equation of the parabola in standard form.
Step-by-step explanation:
Answer:
x = 36.9°
Step-by-step explanation:
We need to find out what sides of the triangle we have, <em>so we can find the formula for the missing angle, x.</em>
We have been given the <em>opposite</em> and <em>hypotenuse</em> so we are using sine
SOH, CAH, TOA
sin (x) = opp ÷ hyp
<em>Substitute in the values</em>
sin (x) = 9 ÷ 15
<em>Simplify</em>
sin (x) = 0.6
<em>Rearrange to find x</em>
x = sin^-1(0.6) - Type this into your calculator
<h3>
sin^-1 is the inverse or opposite of sin</h3>
x = 36.8698... ≈ 36.9°
5 3/4 = 23/4.
-4 5/6 = -29/6.
23/4 - (-29/6) = 10 7/12
