Answer:
Step-by-step explanation:
We can use the geometric mean theorem:
The altitude on the hypotenuse is the geometric mean of the two segments it creates.
In your triangle, the two segments are MP and PO.
MP + PO = MO
MP + 3 = 15
MP = 12
Then,
Answer:
(a). ; (b). <em>33 to 40 </em>
Step-by-step explanation:
Use "magic fraction"
<em>(a).</em> Distance covered by runner is 33 yards
Whole distance is 40 yards
The portion of the race that the runner has completed is
<em>(b).</em> The portion of the race that the runner has completed is <em>33 to 40</em>
So for this equation we're going to complete the square.
Firstly, what two terms have a product of 120x^2 and a sum of 29x? 24x and 5x. Replace 29x with 24x + 5x:
Next, factor 4x^2 + 24x and 5x + 30 separately. Make sure that they have the same quantity inside the parentheses:
Now you can rewrite the equation as:
Now using zero product property, solve for x:
In short, x = -1.25 and -6
