The mass of sodium chloride required for 1. 8 × 10^3 people is 3. 6 × 10^5 grams. Option A is the correct answer.

<h3>How do you calculate the mass of sodium chloride required?</h3>

Given that weigh of the person is 50 KG. The mass of the sodium chloride in one person is given below.

$1 \;\rm Person = 2\times 10^2\;\rm g$

The mass of sodium chloride is calculated as given below.

$1.8\times 10^3 \;\rm Person = 2\times 10^2 \times 1.8\times 10^3$

$1.8\times 10^3 \;\rm Person = 3.6\times 10^5\;\rm g$

Hence we can conclude that the mass of sodium chloride required for 1. 8 × 10^3 people is 3. 6 × 10^5 grams. Option A is the correct answer.

Answer:

1- 51.496yd 2- 39.25ft 3- 163.28cm 4- 53.38mm 5- 50.24in 6-94.2ft 7-18.84yd 8- 207.24m

Step-by-step explanation:

So how you do circumference is you find the diameter and times it by pi.

for 1. you will do 8.2 times 2 for the diameter then times it by pi and get 51.496 yards.

for 2 you would do 12.5 times pi and get 39.25ft

for 3 you would do 26 times 2 which is 52 then multiply it by pi which is 163.28cm

for 4 you do 17 times pi which is 53.38mm

for 5 you do 16 times pi which is 50.24in

for 6 you do 30 times pi which is 94.2ft

for 7 you do 3 times 2 which is 6 then multiply by pi which is 18.84yd

for 8 you do 33 times 2 which is 66 then multiply by pi which is 207.24m.

Prove<br><br> that BUGS is a trapezoid with coordinates B(-2,-1), U(0,3), G(3,2) and S(4,-3).

telo118 [61]

Answer:

Proved

Step-by-step explanation:

Given

$B =(-2,-1)$

$U = (0,3)$

$G = (3,2)$

$S = (4,-3)$

Required

Prove BUGS is a trapezoid

Given the coordinates, to prove a trapezoid; all we need to do is to check if one pair of sides is parallel.

<u></u>

<u>Taking BU and GS as a pair</u>

First, we calculate the slope using:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

For BU

$B =(-2,-1)$ --- $(x_1,y_1)$

$U = (0,3)$ --- $(x_2,y_2)$

So, we have:

$m = \frac{3 - -1}{0- -2}$

$m = \frac{4}{2}$

$m = 2$

For GS

$G = (3,2)$ --- $(x_1,y_1)$

$S = (4,-3)$ --- $(x_2,y_2)$

So, we have:

$m = \frac{-3-2}{4-3}$

$m = \frac{-5}{1}$

$m = -5$

<em>The slope of BU and GS are not the same; hence, they are not parallel.</em>

<u>Taking BS and GU as a pair</u>

Calculate the slope

For BS

$B =(-2,-1)$ --- $(x_1,y_1)$

$S = (4,-3)$ --- $(x_2,y_2)$

So, we have:

$m = \frac{-3 - -1}{4- -2}$

$m = \frac{-2}{6}$

$m = -\frac{1}{3}$

For GU

$G = (3,2)$ --- $(x_1,y_1)$

$U = (0,3)$ --- $(x_2,y_2)$

So, we have:

$m = \frac{3-2}{0-3}$

$m = \frac{1}{-3}$

$m = -\frac{1}{3}$

The slope of BS and GU are the same; hence, they are parallel.

<em>BUGS is a trapezoid because BS and GU have the same slope</em>

A rock is thrown into the air. The height of the rock is modeled by s(t) = −16tଶ + 64t + 80 feet for t ≥ 0 seconds. The rock hit

ExtremeBDS [4]

Answer:

144 feets

Step-by-step explanation:

Look on s(t) like quadratic function. We need to find maximum of the function using 1st diferetioal:

s(t)=-16t^2+64t+80

s’(t)=-32t+64

S’(t)=0 if t=2

For t>2, s’(t)<0

For t<2, s’(t)>0. So the maximum od function is in the point 2.

S(2)=-16*4+64*2+80=-64+128+80=144
