Answer:

Step-by-step explanation:

One complete turn is 1 perimeter (aka circumference).

We have to find the length it turned, hence, its circumference.

The formula for circumference (C) of a circle is:

$C=2\pi r$

Where r is the radius

The radius is HALF of diameter. Given diameter is 250, the radius is:

r = 250/2 = 125 feet

Now, substituting in formula we have:

$C=2\pi r\\C=2\pi (125)\\C=250\pi\\C=785.4$

So, it turned 785.4 feet with 1 rotation.

The correct answer is A

Answer:

if I read your screen correctly

$F radius = 5 x {10}^{-8 }$

$Sr radius = 2 x {10}^{-7}$

Step-by-step explanation:

divide the larger one (Sr) by smaller one (F)

the coefficient = 2/5

the exponent = -7-(-8)

can you get the answer from there, don't forget to simplify

in the game of hearts, four players are each dealt 13 cards from a deck of 52. is this a function? if so, what are the domain an

skelet666 [1.2K]

Based on the fact the game of hearts, four players are each dealt 13 cards from a deck of 52

The domain is the deck of 52 cards
codomain is 4 players
function, f(k) maps a card to each player
It is surjective

This is further explained below.

<h3>What is a surjective Function?</h3>

A surjective function is a kind of function that exists in mathematics that ensures that any element y may be transferred to element x in such a way that f(x) equals y.

To put it another way, each element that makes up the function's codomain is the mirror image of at least one element that makes up the domain.

Generally, function, f(k) maps a card to each player

And since each player is dealt 13 cards st 13 of the cards are mapped to each player.

It is a function as one card is mapped to one and only one player.

The function is not injective because 13 cards 1 are mapped to one player so it is a many-one function but the injective function does not map two elements to a common clement.

In conclusion, It is surjective as each player is dealt 13 cards. the function is not injective hence rot bijective.

Find the length of the arc.<br> A. 15π mi<br> B. 5400π mi<br> C. 135π mi<br> D. 125π16 mi

weqwewe [10]

Answer:

A. 15π mi

Step-by-step explanation:

First find the circumference

C = 2*pi*r

C = 2 * pi*18

C = 36pi

The arc is 150 degrees

The fraction of the circle is

150/360 = 5/12

Multiply this by the circumference

5/12 * 36 pi

15 pi

An aircraft (at Z) is spotted by two observers (at X and Y) who are L = 1950 feet

Blizzard [7]

Answer:

889.70 feets

Step-by-step explanation:

From the solution diagram attached :

C = 180 - (40 + 45) = 95°

According to the sine rule :

Sin95 / 1950 = Sin40 / b = Sin 45 / a

1950 sin40 / sin 95 = b = 1248.22 ft

1950 sin 45 / sin 95 = a = 1384.13 ft

Sin 40 = h / 1384.13

h = 1384.13 * sin 40

h = 889.70 feets
