Answer:
a₄ = 50
Step-by-step explanation:
work back from the seventh term a₇ using the reverse of the term to term rule , that is
divide by 2 then subtract 3
a₇ = 442
a₆ = 442 ÷ 2 - 3 = 221 - 3 = 218
a₅ = 218 ÷ 2 - 3 = 109 - 3 = 106
a₄ = 106 ÷ 2 - 3 = 53 - 3 = 50
Answer:
[tex]a_{4}=50[/tex]
Step-by-step explanation:
[tex]a_{4} = 50[/tex]
a₇ = 442
a₆ = 442 ÷ 2 - 3 = 221 - 3 = 218
a₅ = 218 ÷ 2 - 3 = 109 - 3 = 106
a₄ = 106 ÷ 2 - 3 = 53 - 3 = 50

Antonio has 2 2/3 of a piece of wood that he wants to cut into 4 pieces. How long should he cut each piece?
A 8 2/3
B 10 2/3
C 8/3
D 2/3
Answers
Answer:
D 2/3
explanation:
[tex]\bold{total \ length \ \div \ number \ of \ pieces }[/tex]
solve
[tex]\sf 2\dfrac{2}{3} \div 4[/tex]
reciprocal to change signs
[tex]\sf \dfrac{8}{3} \ * \ \dfrac{1}{4}[/tex]
simplify
[tex]\sf \dfrac{2}{3}[/tex]
Solution:
To find the measure of each piece, divide the total piece of wood (2 2/3) by the number of pieces Antonio wants to cut (4).
From the following, we obtained:
[tex]\rightarrow 2 \dfrac{2}{3} \div 4[/tex]
Convert 2 2/3 into an improper fraction:
[tex]\rightarrow 2 \dfrac{2}{3} \div 4[/tex]
[tex]\rightarrow \dfrac{2 \times 3 + 2}{3} \div 4\\[/tex]
[tex]\rightarrow \dfrac{6 + 2}{3} \div 4\\[/tex]
[tex]\rightarrow \dfrac{8}{3} \div 4\\[/tex]
Simplifying the expression:
[tex]\rightarrow \dfrac{8}{3} \div 4\\[/tex]
[tex]\rightarrow \dfrac{8}{3} \times \dfrac{1}{4} \\[/tex]
[tex]\rightarrow \dfrac{8}{3 \times 4}[/tex]
[tex]\rightarrow \dfrac{8}{12} = \boxed{\dfrac{2}{3}}[/tex]
Thus, Antonio should cut 2/3 of wood for each piece.
Express as a sum.

Using Cos formula of a triangle
let BA be x
x² = a² + b² -2abCos(90°)
x² = 64 + 196
x = √260
To find <B using Cos again
b² = a² + c² - 2acCos(B)
196 = 64 + 260 - 2 * 8 * √260 * cosB
196=324 - 16√260 *cosB
324-196=16√260CosB
8 = √260CosB
CosB = 8/√260
B = cos-¹(8/(√260))

What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
We can determine the discounted fee for each rental fee by looking at the coordinates on the graph.
The x-axis represents the rental fee, and the y-axis represents the discounted fee.
For example, at a rental fee of 10, the discounted fee is 5, so we have the point (10, 5) on the graph.
To calculate how much each discounted fee is less than the rental fee, we can subtract the discounted fee from the rental fee.
For example, at a rental fee of 10 and a discounted fee of 5, the discounted fee is $5 less than the rental fee of $10.
This means that the discounted fee is 50% less than the rental fee.
Using this method for each point on the graph, we get:
At a rental fee of 10, the discounted fee is 5, which is $5 less than the rental fee.
Therefore, the discounted fee is 50% less than the rental fee.
At a rental fee of 20, the discounted fee is 15, which is $5 less than the rental fee.
Therefore, the discounted fee is 25% less than the rental fee.
At a rental fee of 30, the discounted fee is 25, which is $5 less than the rental fee. Therefore, the discounted fee is 16.67% less than the rental fee.
At a rental fee of 40, the discounted fee is 35, which is $5 less than the rental fee. Therefore, the discounted fee is 12.5% less than the rental fee.
Thus,
Each discounted fee is $5 less than the corresponding rental fee, and the percentage discount decreases as the rental fee increases.
