Monica built a remote-controlled, toy airplane for a science project. To test the plane, she launched it from the top of a build

ing. The plane traveled a horizontal distance of 50 feet before landing on the ground. A quadratic function which models the height of the plane, in feet, relative to the ground, at a horizontal distance of x feet from the building is shown.
Since the domain represents the airplane while it was in the air, the values of the domain should be restricted to the interval [, ].

Answer:

[0,50]

Step-by-step explanation:

The function takes from value the distance from the plane to the building, and returns the height of the plane at that point in feets. Assuming that the plane goes always down, it will always be up to the height of the building. Note that the horizontal distance the plane travels at any point is equivalent to the distance of the plane with the building at that point, because the building is perpendicular to the ground. So, at the end of the travel the plane will be 50 feets away from the building. SInce it starts at 0 distance, then the domain of the function is [0,50]

You are measuring the height of a statue. You stand 17 feet from the base of the statue. You measure the angle of elevation from
olga_2 [115]

Answer:

height ≈ 31 ft

Step-by-step explanation:

The illustration below will form a right angle triangle. He is standing 17 ft away from the base of the statue.  The angle of elevation from the ground to the top of the statue  is 61°. The height of the statue can be computed below.

adjacent side of the triangle = 17 ft

opposite side = a

Using SOHCAHTOA principle

tan 61° = opposite/adjacent

tan 61° = a/17

cross multiply

a = 17 tan 61°

a = 17 × 1.80404775527

a = 30.6688118396

a ≈ 31 ft

A coordinate plane with a line passing through (0, negative 3), (2, 0), and (4, 3).
adell [148]

Answer:

y=\frac{3}{2}x-3

Step-by-step explanation:

The given line passes through: (0,-3), (2,0), and (4,3).

We first of all find the slope using m=\frac{y_2-y_1}{x_2-x_1}

Using (x_1=0,y_1=-3),and\:(x_2=2,y_2=0) we find the slope to be

m=\frac{0--3}{2-0}=\frac{3}{2}

The equation is given by y=mx+c, where m=\frac{3}{2} is the slope and c=-3 is the y-intercept.

Therefore the equation is y=\frac{3}{2}x-3
