Answer:

D. plane

Step-by-step explanation:

A. is incorrect because three points don't make a point.

Can Someone Explain algebraic fractions to me please? I Don't understand It
lbvjy [14]
Algebraic fractions are the same as normal fractions, but they have algebraic expressions as the numerator/denominator. 

For example, \frac{2}{7} is a normal fraction, but \frac{3y - 2x}{2y + 5x} is an algebraic fraction.

The angle of elevation from the top of a house to a jet flying 2 miles above the house is x radians. If d represents the horizon
alisha [4.7K]

Answer:

d = 2cot(x) or d = 2/tan(x)

Step-by-step explanation:

The vertical distance from the jet to the top of the house represents the opposite side to the 'x' angle, while the horizontal distance, d, represents the adjacent side. Since we do not know the hypotenuse, the tangent and cotangent functions are the preferable choices:

tan (x) = \frac{2}{d}\\d = \frac{2}{tan (x) }\\cot (x) = \frac{d}{2} \\d= 2cot(x)

Therefore, the distance 'd' can be expressed as d = 2cot(x) or d = 2/tan(x).
