Answer: 3.96 meters
Step-by-step explanation:
Draw a Right triangle as the one shown in the image attached, where "x" is the distance from the base of the pole to the point in which the cable is attached to the ground.
In this case you need to use the Pythagorean Theorem. According to this theorem:
Where "a" is the hypotenuse and "b" and "c" are the legs of the Right triangle.
If you solve for one of the legs, you get:
In this case, you can identify that:
Substituting values, you get the following result:
2x2=4 so if you multiply a number times another one it will add up to a greater number
Answer:
The points at which the graph crosses or touches x- axis, give the real roots of the function (or zeros of the function) represented by the graph. If the graph touches x-axis and turns back, then it would be a double root at that point.

Answer:
for second question
first length is 9cm
Area=l*b
= 9cm *9cm
=81<em><u>cm</u></em>
then, For semicircle
radius is 9 cm
area= 1/2*9cm
now , area of two semi circle = 2*1/2*9
= 9 cm
now area of shaded = 81-9
=72
