A blimp provides aerial television views of a tennis game. The television camera sights the stadium at a 17degrees angle of depr
BaLLatris [955]

Answer:

1379.31meters  is the​ line-of-sight distance from the television camera to the base of the stadium​ .

Step-by-step explanation:

As given

A blimp provides aerial television views of a tennis game.

The television camera sights the stadium at a 17degrees angle of depression. The altitude of the blimp is 400m.

Now by using the trignometric identity .

sin\theta = \frac{Perpendicular}{Hypotenuse}

As the figure is given below .

Perpendicular = AC = 400 m

Hypotenuse = AB

\theta = 17^{\circ}

Putting all the values in the identity .

sin17^{\circ} = \frac{400}{AB}

0.29\ (Approx)= \frac{400}{AB}

AB= \frac{400}{0.29}

AB = 1379.31 meters

Therefore the 1379.31 meters  is the​ line-of-sight distance from the television camera to the base of the stadium​ .

Andrews [41]

Answer: =\frac{17}{60}\quad \left(\mathrm{Decimal:\quad }\:0.28333\dots \right)

Step-by-step explanation:

\left(\frac{7}{10}\right)-\left(\frac{5}{12}\right)

=\frac{7}{10}-\frac{5}{12}

=\frac{42}{60}-\frac{25}{60}

=\frac{42-25}{60}

=\frac{17}{60}

The number of hours, t, it takes a boat to travel 15 miles upstream is represented
iogann1982 [59]

The equation of c is an illustration of subject of formula

The equation of c in terms of r and t is c = r - 15/t

<h3>How to determine the equation?</h3>

The equation is given as:

t = 15/(r - c)

Cross multiply

t(r - c) = 15

Divide both sides by t

r - c = 15/t

Subtract r from both sides

-c = -r + 15/t

Multiply both sides by -1

c = r - 15/t

Take LCM

c = \frac{rt - 15}{t}

Hence, the equation of c in terms of r and t is c = \frac{rt - 15}{t}
