Answer:
<h2>Increase.</h2>
Step-by-step explanation:
Two-dimensional space is modelled by the coordiante system with 4 quadrants only, and the axis are x and y, the independent and the dependent variables, respectively.
On the other hand, the three-dimensional space has three coordinates, x, y and z. The extra coordinate allows to have a three-dimensional space. Also, this extra coordinate increases the number of quadrants, actually, they are called octants, becayse they are eight.
Therefore, the word missing here is "increase".
The horizontal and the vertical components of the vector are -8.86 and -1.566 respectively.
<h3>What is a vector?</h3>
A vector is a quantity that has both magnitude and direction.
To calculate the horizontal components of the vector, we use the formula below.
Formula:
- Vx = Vcos∅............ Equation 1
Given:
Substitute into equation 1
- Vx = 9cos190°
- Vx = 9×(-0.9848)
- Vx = -8.86
Also, to find the vertical component of the vector, we use the formula below
- Vy = Vsin∅............. Equation 2
Also, substitute these values above into equation 2
- Vy = 9sin190°
- Vy = 9×(-0.174)
- Vy = -1.566
Hence, the horizontal and the vertical components of the vector are -8.86 and -1.566 respectively.

Answer:
Part A: 480 ounces of water are left in the water tank.
Part B: he will drink 3 tanks of water in 30 days.
Step-by-step explanation:
Part A:
5x8x16 = 6x16 = 1/2x8x16
=640 = 96 = 64
=480
Part B:
4x30 divided by (5x8) = 120 divided by 40 = 3
