If both cars in Exercise 62 are on one side of the plane and if the angle of depression to one car is 38∘ and that to the other
Sati [7]

The two cars lying on one side of the plane are 50 meters apart.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

let us assume that the height is 100 m. Let d represent the horizontal distance. For depression of 38°, Ф = 90 - 38 = 52°, hence:

tan(52°) = d / 100

d = 128 m

For depression of 52°, Ф = 90 - 52 = 38°, hence:

tan(38°) = d / 100

d = 78 m

Distance apart = 128 - 78 = 50 m.

The two cars lying on one side of the plane are 50 meters apart.

What is the rate of change from x = n to x = 2n?​
puteri [66]

Answer:

\dfrac{-8}{\pi}

Step-by-step explanation:

The rate of change of the function f(x) from point x_1 to point x_2 can be calculated using formula

\dfrac{f(x_2)-f(x_1)}{x_2-x_1}

Given

x_1=\pi\\ \\x_2=2\pi

From the graph of the function

f(x_1)=f(\pi)=4\\ \\f(x_2)=f(2\pi)=-4

So, the rate of change is

\dfrac{f(x_2)-f(x_1)}{x_2-x_1}=\dfrac{-4-4}{2\pi -\pi}=\dfrac{-8}{\pi}

Solve for w. <br><br> 1/3w + 5/6w - 2 = -w
Scorpion4ik [409]

Answer: w=\frac{12}{13}

Step-by-step explanation:

To solve for w, we want to isolate the variable.

\frac{1}{3}w +\frac{5}{6}w-2=-w        [add both sides by 2 and w]

\frac{1}{3}w +\frac{5}{6}w+w=2           [convert to same denominator]

\frac{2}{6}w +\frac{5}{6}w+\frac{6}{6} w=2         [add]

\frac{13}{6} w=2                          [multiply both sides by 6/13]

w=\frac{12}{13}

Now we know that w=\frac{12}{13}.
