Let u = ⟨–2, 6⟩, v = ⟨3, 2⟩, and w = ⟨–1, 4⟩. What is the magnitude and direction angle of 2(u + v) – 3w?

2.8; θ = 45.0°
6.4; θ = 38.7°
28.0; θ = 92.0°
41.0; θ = 51.3°

Answers

u = ⟨-2, 6⟩

v = ⟨3, 2⟩

w = ⟨-1, 4⟩

u + v = ⟨-2, 6⟩ + ⟨3, 2⟩

u + v = ⟨-2 + 3, 6 + 2⟩

u + v = ⟨1, 8⟩

2 (u + v) = 2 ⟨-1, 8⟩

2 (u + v) = ⟨2 • 1, 2 • 8⟩

2 (u + v) = ⟨2, 16⟩

-3 w = -3 ⟨-1, 4⟩

-3 w = ⟨-3 • (-1), -3 • 4⟩

-3 w = ⟨3, -12⟩

2 (u + v) - 3 w = 2 (u + v) + (-3 w)

2 (u + v) - 3 w = ⟨2, 16⟩ + ⟨3, -12⟩

2 (u + v) - 3 w = ⟨2 + 3, 16 + (-12)⟩

2 (u + v) - 3 w = ⟨5, 4⟩

Then the magnitude of this vector is

||2 (u + v) - 3 w|| = √(5² + 4²) = √41 ≈ 6.403

so the second choice is correct.

When would Casey pay the same amount to be a member of either gym? How much would he pay?

Answers

Answer: After 6 Months Casey would have paid $450 at either gym.

Step-by-step explanation:

Since we're looking for these two gyms cost the same, we need to make the equation compare the two together:

35x + 240 = 75x (the 1st gym with a joining fee $240 and 35 monthly equals $75 monthly)

Subtract 35x from both sides:

35x - 35x + 240 = 75x - 35x

240 = 40x

Divide by 40:

240 / 40 = 6

6 = x

So they cost the same after 6 months

35 * 6+ 240 = 75 * 6

450 = 450

And you'll be spending $450 in total.

Answers

Answer:

x = -3

Step-by-step explanation:

3x + 9 = 12x + 36 (rewrite)

3x - 12x + 9 = 36 ------> 3x - 12x = 36 - 9

3x - 12x = 36 - 9 (collect like terms)

-9x = 36 - 9 ( substract)

-9x = 27 (divide both sides for the answer)

A cylinderical container of height 28cm and diameter 18cm is filled with water. The water is then poured into another container with a rectangular base 27cm and width 11cm. Calculate the depth of the water in the container ( take π=22/7)

Answers

Answer:

h = 24 cm

Step-by-step explanation:

volume of water in the cylinder = volume of water in the rectangular base container

But ,

volume of cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

where:  is the radius and h is the height.

volume of cuboid = length x width x height

                             = l x w x h

So that;

[tex]\pi[/tex][tex]r^{2}[/tex]h = l x w x h

But, r = [tex]\frac{diameter}{2}[/tex] = [tex]\frac{18}{2}[/tex] = 9 cm, height of cylinder = 28 cm, length = 27 cm, width = 11 cm, [tex]\pi[/tex] = [tex]\frac{22}{7}[/tex].

Thus,

[tex]\frac{22}{7}[/tex] x [tex](9)^{2}[/tex] x 28 = 27 x 11 x h

[tex]\frac{22}{7}[/tex] x 81 x 28 = 27 x 11 x h

7128 = 297h

h = [tex]\frac{7128}{297}[/tex]

  = 24

h = 24 cm

The depth of the water in the container is 24 cm.

When converting a decimal to a fraction, the digits to the right of the decimal point become the _____
of the fraction.

Answers

Answer:

numerator

Step-by-step explanation:

it becomes the numerator because however many places over the numbers to the decimals are is the amount if its in like the 10th 100th 1000th and so on. But if there is a one or more to the left side of the decimal it becomes the whole number, so that leaves the numerator. So that is how the numerator is the answer.
