Answer:

18.04 gallons

Step-by-step explanation:

The cost of filling the empty tank of the vehicle is $71.98.  

If each gallon of gas costs $3.99, then we have to find the volume of the sedan's tank in gallons.

Now, $3.99 is the cost of 1 gallon of gas.

Hence, $71.98 will be the cost of \frac{71.98}{3.99} = 18.04 gallons.

Therefore, the volume of the tank is 18.04 gallons. (Answer)

The area of the smallest equilateral triangle with one vertex on each of the sides of the right triangle with side lengths and <
Gre4nikov [31]
Set up the given triangle on x-y coordinates with right angle at (0,0). So the two vertices are at (5,0) and (0,2sqrt{x} n]{3})

let (a,0) and (0,b) be two vertices of the<span> equilateral triangle. So the third vertex must be at </span>(\frac{a+\sqrt{3}b}{2} ,  \frac{b+\sqrt{3}a}{2} )

for a pt (x,y) on line sx+ty=1, the minimum of \sqrt{x^{2} + {y^{2} }
equals to \frac{1}{ \sqrt{ s^{2} +  t^{2} } }

smallest value happens at \frac{10 \sqrt{3} }{67}

so area is \frac{75\sqrt{3}}{67}

hence m=75, n=67, p=3
m+n+p = 75+67+3 = 145

A firework is launched at the rate of 10 feet per second from a point on the ground 50 feet from an observer. to 2 decimal place
Kazeer [188]

The rate of change of the angle of elevation when the firework is 40 feet above the ground is 0.12 radians/second.

First we will draw a right angle triangle ΔABC, where ∠B = 90°

Lets, assume the height(AB) = h and base(BC)= x

If the angle of elevation, ∠ACB = α, then

tan(α) = \frac{AB}{BC} = \frac{h}{x}

Taking inverse trigonometric function, α = tan⁻¹ (\frac{h}{x}) .............(1)

As we need to find the rate of change of the angle of elevation, so we will differentiate both sides of equation (1) with respect to time (t) :

\frac{d\alpha}{dt}=[\frac{1}{1+ \frac{h^2}{x^2}}]*(\frac{1}{x})\frac{dh}{dt}

Here, the firework is launched from point B at the rate of 10 feet/second and when it is 40 feet above the ground it reaches point A,

that means h = 40 feet and \frac{dh}{dt} = 10 feet/second.

C is the observer's position which is 50 feet away from the point B, so x = 50 feet.

\frac{d\alpha}{dt}= [\frac{1}{1+ \frac{40^2}{50^2}}] *\frac{1}{50} *10\\ \\ \frac{d\alpha}{dt} = [\frac{1}{1+\frac{16}{25}}] *\frac{1}{5}\\ \\ \frac{d\alpha}{dt} = [\frac{25}{41}] *\frac{1}{5}\\   \\ \frac{d\alpha}{dt}= \frac{5}{41} =0.1219512

= 0.12 (Rounding up to two decimal places)

So, the rate of change of the angle of elevation is 0.12 radians/second.
