line L passes through point (2, -5) and is perpendicular to the line with equation y=7. determine the equation of line L
Andrew [12]

Answer:

The equation of the line L is x=2

Step-by-step explanation:

we know that

The line y=7

Is a horizontal line (parallel line to the x-axis)

The slope of a horizontal line is equal to zero

A line L perpendicular to the given line must be a vertical line (parallel to the y-axis)

The slope of the line L is undefined

The line L passes through the point (2,-5)

therefore

The equation of the line L will be equal to the x-coordinate of the given point

x=2

Question 2

Answer:

<em>The firefighter should extend the ladder at 54° of elevation.</em>

Step-by-step explanation:

<u>Trigonometric Ratios</u>

The ratios of the sides of a right triangle are called trigonometric ratios. There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant, and cotangent.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

Selecting any of the acute angles as a reference, it has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.

<em>Tangent Ratio:</em>

\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}

The woman is trapped at 91 feet up from the ground, and the firetruck is 67 feet away from the building.

The wall, the ground, and the ladder form a right triangle, where θ is the horizontal angle of the ladder.

Being the height of the woman the opposite leg and the distance where the firetruck is parked, the adjacent leg:

\displaystyle \tan\theta=\frac{91}{67}=1.3582

The angle is calculated as the inverse tangent:

\theta=arctan(1.3582)\approx 54^\circ

The firefighter should extend the ladder at 54° of elevation.

153 is 0.9% of what number? Tell which equivalent ratios you used to find the solution
Naddik [55]
0.9% / 100% = 0.009
= 9/1000

equivalent ratio:
9/1000 = 153/x

cross multiply
9x = 153,000
x = 153,000/9
x = 17,000

153/17,000 = 0.009
