Answer: FIRST OPTION
Step-by-step explanation:
<h3>
The missing picture is attached.</h3>
By definition, given a Quadratic equation in the form:
Where "a", "b" and "c" are numerical coefficients and "x" is the unknown variable, you caN use the Quadratic Formula to solve it.
The Quadratic Formula is the following:
In this case, the exercise gives you this Quadratic equation:
You can identify that the numerical coefficients are:
Therefore, you can substitute values into the Quadratic formula shown above:
You can identify that the equation that shows the Quadratic formula used correctly to solve the Quadratic equation given in the exercise for "x", is the one shown in the First option.
120 ft... a flat vertical line is 180 degrees, and since this is a 30,60,90 triangle, your equation is... 180-60=distance John is to the base
Answer:
3 1/3
Step-by-step explanation:
It is 3 1/3 because 2/3 x 5 equals 3.33333333333 which we shorten to 3.3 which equals 3 3/10 which that equals 3 1/3.
Answer:
2
Step-by-step explanation:
The given equation of line is
We need to find the slope of a line which is perpendicular to the given line.
The given equation can be rewritten as
...(i)
If a line is defined as 
, then the slope of the line is
In equation (i), a=3, b=6 and c=18. So, slope of the line is
Let 
be the slope of perpendicular line.
We know that product of two perpendicular line is -1.
Multiply both sides by -2.
Therefore, the slope of perpendicular line is 2.
Answer:
40 feet
Step-by-step explanation:
Given : The deck is at a height of 520 ft. She sees her friend on the ground below at an angle of depression of 85.6 degrees.
To Find : What is the distance between the two? Round your answer to the nearest tenth of a foot.
Solution :
Refer the attached figure
Height of deck =AB =520 ft.
Angle of depression ∠C = 85.6°
We are supposed to find length of BC i.e. distance between two.
We will use trigonometric ratios :
Thus the distance between two is 40 feet
