Answer:
1st pic) 17.8
2nd pic) 16.8
3rd pic) 9.1
4th pic) 13.5
Step-by-step explanation:
<u>1st pic:</u>
(write equation) Cos 27 (cos 27 = 0.89) = ![\frac{x}{20}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B20%7D)
(new equation) 0. 89 = ![\frac{x}{20}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B20%7D)
(multiply 20 on both sides) 0.89 x 20 =
x 20
(solve) 17.8 = x
<u>2nd pic:</u> ![tan = \frac{adjacentx}{hypothenuse}](https://tex.z-dn.net/?f=tan%20%3D%20%5Cfrac%7Badjacentx%7D%7Bhypothenuse%7D)
(write equation) tan 40 (tan 40 = 0.84) = ![\frac{32}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B32%7D%7Bx%7D)
(new equation) 0.84 = ![\frac{32}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B32%7D%7Bx%7D)
(multiply 32 on both sides) 0.84 x 20 =
x 20
(solve) 16.8 = x
<u>3rd pic:</u> ![cos = \frac{adjacent}{hypothenuse}](https://tex.z-dn.net/?f=cos%20%3D%20%5Cfrac%7Badjacent%7D%7Bhypothenuse%7D)
(write equation) cos 55 (cos 55 = 0.57) = ![\frac{16}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7Bx%7D)
(new equation) 0.57 = ![\frac{16}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7Bx%7D)
(multiply 16 on both sides) 0.57 x 16 =
x 16
(solve) 9.1 = x
<u>4th pic:</u> ![tan = \frac{adjacentx}{hypothenuse}](https://tex.z-dn.net/?f=tan%20%3D%20%5Cfrac%7Badjacentx%7D%7Bhypothenuse%7D)
(write eqaution) tan 42 (tan 42 = 0.90) = ![\frac{x}{15}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B15%7D)
(new equation) 0.90 = ![\frac{x}{15}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B15%7D)
(multiply 15 on both sides) 0.90 x 15 =
x 15
(solve) 13.5 = x

A.
Because in mathematics, a geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
The ordered pair which is a solution to the given inequality is: C. (2, 1).
<h3>What is an inequality?</h3>
An inequality can be defined as a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following arguments:
- Less than (<).
- Greater than (>).
- Less than or equal to (≤).
- Greater than or equal to (≥).
Next, we would test the ordered pair with the given inequality to determine a solution as follows:
For ordered pair (4, 4), we have:
3x + 2y < 15
3(4) + 2(4) < 15
12 + 8 < 15
20 < 15 (False).
For ordered pair (3, 3), we have:
3x + 2y < 15
3(3) + 2(3) < 15
9 + 6 < 15
15 < 15 (False).
7x - 4y > 9
7(3) - 4(3) > 9
21 - 12 > 9
9 > 9 (False)
For ordered pair (2, 1), we have:
3x + 2y < 15
3(2) + 2(1) < 15
6 + 2 < 15
8 < 15 (True).
7x - 4y > 9
7(2) - 4(1) > 9
14 - 4 > 9
10 > 9 (True)
For ordered pair (1, 0), we have:
3x + 2y < 15
3(1) + 2(0) < 15
3 + 0 < 15
3 < 15 (True).
7x - 4y > 9
7(1) - 4(0) > 9
7 - 4 > 9
3 > 9 (False)
