<em>Note: I am assuming we have to determine the value of the side 'x'.</em>
Answer:
The value of x = 8.1 units
Step-by-step explanation:
<em>Note: I am assuming we have to determine the value of the side 'x'.</em>
Given
Angle Ф = 32°
To determine:
x = ?
Using the trigonometric ratio
tan Ф = opposite / adjacent
here
Ф = 32°
opposite to angle 32° = x
adjacent to angle 32° = 13
Therefore,
substituting adjacent = 13, Ф = 32°, opposite = x in the equation
tan Ф = opposite / adjacent


x = 8.1 units tan 32° = 0.62
Therefore, the value of x = 8.1 units
In a conventional gradient, the amount of money in period one is known as the base amount.
<h3>What is an arithmetic gradient? </h3>
An arithmetic gradient series is a cash flow series that either increases or decreases by a constant amount each period.
<h3>What is a base amount?</h3>
Base amount is the fundamental numerical assumption from which something is begun or estimated in a given arithmetic series. It usually occurs in period for a conventional gradient.
Thus, in a conventional gradient, the amount of money in period one is known as the base amount.

Answer:
The answer is 9(7x – 1).
Step-by-step explanation:
63x – 9
3 × 3 × 7 × x – 3 × 3
9(7x – 1)
Thus, The answer is 9(7x – 1).

<h3>What is price index?</h3>
An index number expressing the level of a group of commodity prices relative to the level of the prices of the same commodities during an arbitrarily chosen base period and used to indicate changes in the level of prices from one period to another.
Given:
Comm. p0 q0 p1 q1 p0q0 p1q0 p1q1 p0q1
A 25 750 30 960 18750 750 28800 24000
B 30 450 25 550 13500 750 13750 16500
C 5 250 6 360 1250 30 2160 1800
D 6 90 7 210 540 42 1470 1260
E 10 140 10 190 1400 100 1900 1900
F 4 48 5 65 192 240 365 260
Now,
p0q0 = 35632
p1q0 = 1912
p1q1 = 48445
p0q1= 45720
1) P01(L) =
p1q0/
p0q0 * 100
= 5.36
2) P01(L) =
p1q1/
p0q1 * 100
= 105.96
Dorbish- Bowley
= 5.36+ 105.96/2
=55.66
Marshall- Edgeworth
= 1912+ 48445/35632 + 45720
= 50357/ 81352
= 0.619 *100= 61.9
Fisher's price index
=( 5.36 * 105.96 )^ 0.5
=23.831
