Pennsylvania has a land area of 44,816 spaure miles

Help please !~ I’ll give brainliest! Any help is appreciated :)

In most approximate way it can never be the area of the circle (Accurate area)

This is why because after creating base lines of each triangle it forms an inscribed polygon .

Some little spaces left over each side or b_n

So

h is already approaching to r

and b_1+b_2..b_n is approaching to the perimeter i.e 2πr

Option B

A group of hikers walks 3 miles east and then 1 mile north. After taking a break, they then hike 4 miles east to their final des

geniusboy [140]

Answer:

The vector that describes their hike from their starting position to their final destination is $\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi]$ .

Step-by-step explanation:

In this problem we assume that orthogonal axes coincide with the north and east. We proceed to translate each sentence from statement into vectorial equations:

(i) <em>A group of hikers walks 3 miles east and then 1 mile north:</em>

$\vec r_{A} = 3\,\hat{i}+1\,\hat{j}\,\,\,[mi]$

(ii) <em>After taking a break, they then hike 4 miles east to their final destination:</em>

$\vec r_{B} = 4\,\hat{i}\,\,\,[mi]$

The vector that describes their hike from their starting position to their final destination is the sum of the vectors deducted above. That is:

$\vec r = \vec r_{A}+\vec r_{B}$ (1)

$\vec r = (3\,\hat{i}+1\,\hat{j})+4\,\hat{i}\,\,\,[mi]$

$\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi]$

The vector that describes their hike from their starting position to their final destination is $\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi]$ .

Hey can you please help me posted picture of question

Sidana [21]

Number of outcomes when flipping a coin = 2
Favorable outcome is landing on head.
So,number of favorable outcomes = 1

Probability of getting a head when flipping a coin = $\frac{1}{2}$

Number of outcomes when rolling a dice = 6
Favorable outcomes are rolling 4,5 or 6.
So,number of favorable outcomes = 3

Probability of getting 4 or a bigger number when rolling a dice = $\frac{3}{6}= \frac{1}{2}$

Thus the probability of getting a head when flipping a coin and getting a number equal to or greater than 4 when a dice is rolled = $\frac{1}{2}* \frac{1}{2} = \frac{1}{4}$

So, option A gives the correct answer

Identify the function y=1/2x+6

melamori03 [73]

The given function is linear and slope intercept form.

To identify the function.

<h3>What is function?</h3>

A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Given that:

The given function is

y=1/2x+6

Put this equation into a graphing calculator and you will find that each y value will be 1/2 the x value plus 6

The y-intercept simply means the value of y when x=0.

The slope is 1/2 and the y-intercept is 6.

So, the given function is linear and slope intercept form.
