Given :
The angle of depression is 30 degrees from the bottom of the boat to a
deep sea diver a the depth of 120 ft.
To Find :
The distance x the diver must swim up to the boat to the nearest foot.
Solution :
Let, distance between diver and boat is x.
So,
Therefore, distance the diver must swim up to the boat to the nearest foot is 240 foot.
Hence, this is the required solution.
<em>Answer:</em>
a = 7 & a = −7
<em>Explanation:</em>
Rewrite the equation as
(x+a)(x−a)=x^2−49
Simplify (x+a)(x−a)
x^2−a^2=x^2−49
Move all terms not containing a to the right side of the equation.
−a^2=−49
Multiply each term in −a^2=−49 by −1
a^2=49
Take the square root of both sides of the equation to eliminate the exponent on the left side.
a=±√49
The complete solution is the result of both the positive and negative portions of the solution.
a=7,−7
The sum of 107+0(which has no value so it's like it's not even there) +39+13 = 159
Answer:
When a point gets reflected across the x-axis, the sign of its y-coordinate changes so the coordinates of Q' are (3, 4).
