You fly a hot air balloon 3.5 miles above the ground. What is the measure of BD⌢, the portion of Earth that you can see? Round y

STatiana [176]

Answer:

$\Delta s \approx 334.545\,m$

Step-by-step explanation:

Let assume that Earth is a sphere, the following trigonometric diagram is constructed and presented below. The central angle is given by this inverse trigonometric equation:

$\theta = 2\cdot \cos^{-1} \left(\frac{r}{r+h} \right)$

$\theta = 2\cdot \cos^{-1}\left(\frac{4000\,mi}{4000\,mi+3.5\,mi} \right)$

$\theta = 4.792^{\circ}$

The distance of the portion of Earth that can be seen is:

$\Delta s = \frac{4.792^{\circ}}{360^{\circ}}\cdot (2\pi)\cdot (4000\,mi)$

$\Delta s \approx 334.545\,m$

Which expressions are equivalent to the one below? Check all that apply.log(10^7)

maksim [4K]

The value of expression is 7.

<h3>What is expression?</h3>

An expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.)

Given:

$log 10^{7}$

Now, using property of log

$log b^{a} =$ a log b

So,

$log 10^{7}$ = 7 log 10

As log 10 = 1

$log 10^{7}$ = 7 (1)

$log 10^{7}$ = 7

On a coordinate plane the coordianits of vertices the and t for a polygon are r(-7,3) and r (3,3) what is the length of side rt

NemiM [27]

The length is 10.

Since the two points share the same y-coordinate, the segment rt is horizontal.

This means that the length of the side is simply the difference (in absolute value) between the x coordinates of the two points.

So, we have

$\overline{RT} = |-7-3| = |-10| = 10$
