Let r = ⟨5, –1⟩, s = ⟨6, 0⟩, and t = ⟨–1, –3⟩. Aaron incorrectly determined 2r + 4s – 7t as ⟨41, –23⟩. Review his calculations.
2r + 4s – 7t
2⟨5, –1⟩ + 4⟨6, 0⟩ – 7⟨–1, –3⟩
⟨10, –2⟩ + ⟨24, 0⟩ + ⟨7, –21⟩
⟨41, –23⟩

What mistake did Aaron make?

He added ⟨10, –2⟩ + ⟨24, 0⟩ + ⟨7, –21⟩ incorrectly.
He should have subtracted ⟨7, –21⟩ rather than add.
He did not correctly distribute 4 to both components of s.
He did not correctly distribute the negative when subtracting 7t.

Find the magnitude of the gravitational force
on Mars, with a mass of 6.34 x 1023 kg and a
radius of 3.43 x 106
Answer in units of N.

Answers

Answer:

6849.4

Step-by-step explanation:

m(r)(r) mass and radius equals N

The magnitude of the gravitational force  on Mars is 3.6N

Newton's law of gravitation states that the force is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them. It is given by:

F = G(m₁m₂)/r²

where m₁ and m₂ are mass, r is the distance, G is constant = 6.67 * 10⁻11 Nm²/kg² and F is the force.

Given m₁ = m₂ = 6.34 * 10²³, F = 3.43 x 10⁶, hence:

F = 6.67 * 10⁻¹¹(6.34 * 10²³)² / ( 3.43 x 10⁶)²

F = 3.6N

Hence the magnitude of the gravitational force  on Mars is 3.6N.

Slove the system of equations by useing the substitution method. 2x - 3y=9 y=x-4​

Answers

Answer:

x = 3

y = -1

Step-by-step explanation:

in this system, we are given that y = x - 4

this means that we can take the other equation and replace y with x - 4:

so 2x - 3y=9 turns into

2x -3 (x - 4) = 9

distribute -3 to x and -4:

2x - 3x + 12 = 9

add like terms and subtract 12 from both sides

-x = -3

divide both sides by -1 to get rid of the negative on x:

x = 3

now we have the value of x, so we can replace the x in y = x - 4 with the value we just got

so y = x- 4 turns into

y = (3) - 4

solve and you get

y = -1

David is buying a cheese wheel priced at $ 14 $14dollar sign, 14 before tax. The store charges 8 % 8%8, percent sales tax. What is the total price, including tax, David pays for the cheese wheel? $

Answers

Answer:

$15.12

Step-by-step explanation:

{10 * 0.08 = 0.8

4 * 0.08 = 0.32} (Brackets are here so you can see what I did easier and so you could see how to do it mentally.)

[0.8 + 0.32 = 1.12]

14 + 1.12 = 15.12

David is buying a cheese wheel priced at $14 on 8% sales tax.

David's pays for the cheese wheel is $15.12 .

Given:

Before-tax, the price of cheese wheel = $ 14

Sales tax on cheese wheel = 8%

Sales tax is 8% of $14

[tex]=\frac{8(14)}{100} = \frac{112}{100} = 1.12[/tex]

So, the sales tax on the cheese wheel is $1.12

The total price of the cheese wheel, including tax = $ 14 +  $1.12 = $15.12

Therefore, David's pays for the cheese wheel is $15.12 .

Recall that all angles in a triangle sum up to 180°, therefore:

(9x + 3) + (5x - 2) + (11x - 21) = 180

Combine like terms:

9x + 5x + 11x + 3 - 2 - 21 = 180

25x -20 = 180

Add 20 to both sides:

25x = 200

Divide both sides by 25:

x = 8°

Answer:

Step-by-step explanation:

we know that the sum of the angles in a triangle is 180

(5x-2)+(9x+3)+(11x-21)=180

=5x-2+9x+3+11x-21=180

25x=180+20

25x=200

x=8
