Answer:

Only Cory is correct

Step-by-step explanation:

The gravitational pull of the Earth on a person or object is given by Newton's law of gravitation as follows;

[tex]F =G\times \dfrac{M \cdot m}{r^{2}}[/tex]

Where;

G = The universal gravitational constant

M = The mass of one object

m = The mass of the other object

r = The distance between the centers of the two objects

For the gravitational pull of the Earth on a person, when the person is standing on the Earth's surface, r = R = The radius of the Earth ≈ 6,371 km

Therefore, for an astronaut in the international Space Station, r = 6,800 km

The ratio of the gravitational pull on the surface of the Earth, F₁, and the gravitational pull on an astronaut at the international space station, F₂, is therefore given as follows;

[tex]\dfrac{F_1}{F_2} = \dfrac{ \dfrac{M \cdot m}{R^{2}}}{\dfrac{M \cdot m}{r^{2}}} = \dfrac{r^2}{R^2} = \dfrac{(6,800 \ km)^2}{(6,371 \ km)^2} \approx 1.14[/tex]

∴ F₁ ≈ 1.14 × F₂

F₂ ≈ 0.8778 × F₁

Therefore, the gravitational pull on the astronaut by virtue of the distance from the center of the Earth, F₂ is approximately 88% of the gravitational pull on a person of similar mass on Earth

However, the International Space Station is moving in its orbit around the Earth at an orbiting speed enough to prevent the Space Station from falling to the Earth such that the Space Station falls around the Earth because of the curved shape of the gravitational attraction, such that the astronaut are constantly falling (similar to falling from height) and appear not to experience gravity

Therefore, Cory is correct, the astronauts in the International Space Station, 6,800 km from the Earth's center, are not too far to experience gravity.

You are told x = 8y -4

Replace x in the second equation with 8y-4:

8y-4 + 8y = 6

Combine like terms:

16y-4 = 6

Add 4 to both sides:

16y = 10

Divide both sides by 16:

Y = 10/16

Simplify:

Y = 5/8

Now replace y with 5/8 do find x:

X = 8(5/8) -4 = 5-4 = 1

X = 1, y = 5/8

(1,5/8)

Answer:

x = -1 and y = 3     x = 3 and y = -1

Step-by-step explanation:

Answer:

Step-by-step explanation:

Since the relationship in the table is not a function, Rae could put any values for x that is already in the table.

This will result in repeat of x-values with different corresponding y-values.

Answer:

x=7

Step-by-step explanation:

Answer:

7

Step-by-step explanation:

well

8 x 7 is 56.

3 x 7 is 21

3 x 7 again is 21

21 + 21 is 42

56 + 42 is 98

- x or -7

98 - 7 is 91. it’s 7

x = 7

Answer:

The answer is 13.72 because 1.4^3=2.744 and 2.744*5=13.72

Answer:

The slope is 0, or it is a zero slope.

Step-by-step explanation:

The y coordinate is 4 throughout, and if it were the x coordinate that stayed the same for both points, it would be a undefined slope.

Answer:

60*2= 120 words in 2 minutes.

Step-by-step explanation:

Answer:

120 Words

Step-by-step explanation:

if Jeremy can type 60 words in one minute, we just need to multiple that number against 2 that's how we get 120 words in 2 minutes

Answer:

223 (rounded to closest one) actual answer would be 222.91479275

Step-by-step explanation:

use formula A=Pe^nt

$280 = Pe^0.019(12)

$280 = Pe^0.228, then evaluate the solution by isolating the variable and dividing each side by the factors which don't contain the variable.

P = 222.91479275

Answer:

Step-by-step explanation:

Sine doesn't have an inverse, until you restrict the domain to -pi/2 to pi/2. If you don't restrict the domain, then the inverse doesn't exist. Im going to assume the domain is restricted.

Switch the x and y values

[tex]x= \pi/4+ \sin(y)[/tex]

Subtract pi/4 on both sides

[tex]x- \pi/4= \sin(y)[/tex]

Take the arcsine of both sides

[tex]\arcsin(x- \pi/4)=y[/tex]

Step-by-step explanation:

Answer:

She would have $33 left.

Step-by-step explanation:

First input the $2.50 into the "d" variable and multiply 6 by 2.50.

48−(6)(2.5)

Then, subtract 48 by 15.

48−15

Finally, you have your answer.

Answer: C

Step-by-step explanation:

Answer:

132,  since that angle is corresponding to the line below it.

Using the rule of corresponding angles, we can determine that the transversal line that is intersecting the two parallel lines make x = 132.

Answer:

[tex]sin(36^{\circ})=\approx 0.5878[/tex]

Step-by-step explanation:

We are given that

[tex]sin(36^{\circ)[/tex]

We have to find the value of [tex]sin(36^{\circ)[/tex]

To find the value of [tex]sin(36^{\circ)[/tex]  we will use table of sin

From sin table

We get

[tex]sin(36^{\circ})[/tex]

=0.587785

We have to round off the answer to four decimal places

Therefore,

[tex]sin(36^{\circ})=\approx 0.5878[/tex]
