In a beaded necklace 3/12 are blue and 1/3 are green
The question is: What fractions of the beads are blue or green ?
The answer is: 7/12 of the beads are either blue or green.
Part A: What do the x-intercepts and maximum value of the graph represent in context of the described situation?
Part B: What are the intervals where the function is increasing and decreasing, and what do they represent about the sale and
profit for the company in the situation described?
Part C: What is an approximate average rate of change of the graph from x = 1 to x = 3, and what does this rate represent in
context of the described situation?
The x intercept of the given graph of the company's profit is where the curve of the graph crosses the x-axis.
How to determine the x-interceptIn this figure, the graph crosses the x-axis at x = 0 and x = 6
This represents the profit is 0 when the price is $0 and $6, respectively
The maximum valueThis represents the maximum profit that can be made.
From the graph, the maximum profit is $120
The increasing and the decreasing intervalFrom the graph, the graph increases from x = 0 to x = x = 3, and it decreases from x = 3 to x = 6
These intervals represent when the profit increases, and when it decreases
The average rate of changeThis is calculated as:
[tex]m = \frac{f(b) - f(a)}{b - a}[/tex]
So, we have:
[tex]m = \frac{f(3) - f(1)}{3 - 1}[/tex]
[tex]m = \frac{f(3) - f(1)}{2}[/tex]
Substitute known values
[tex]m = \frac{120 - 60}{2}[/tex]
[tex]m = \frac{60}{2}[/tex]
Simplify
[tex]m = 30[/tex]
Hence, the average rate of change from x = 1 to x = 3 is a profit of $30 per unit sale

Hello.
First, let's recall the Properties of Exponents:
[tex]\displaystyle(\frac{a}{b} )^{m}[/tex]= [tex]\displaystyle\frac{a^{m} }{b^{m}}[/tex]
Let's use this property to simplify the given expression:
[tex]\displaystyle(\frac{9}{16} )^\frac{1}{2}[/tex]
[tex]\displaystyle\frac{9^{\frac{1}{2} } }{16\x^{\frac{1}{2} } }[/tex]
Now, the [tex]\frac{1}{2}[/tex] power means "square root of"
The square root of 9 is 3, and the square root of 16 is 4.
Thus, we have
[tex]\displaystyle\frac{\sqrt{9} }{\sqrt{16} } \\\displaystyle\frac{3 }{4}[/tex]
Therefore, the answer is
[tex]\displaystyle\frac{3}{4}[/tex]

The distance between the oak tree and the maple tree is 9 yards
How to determine the distance?From the diagram, we have the following highlights:
The distance between the maple tree and the end is [tex]28\frac 26[/tex] yardsThe distance between the oak tree and the end is [tex]11\frac 36 + 7\frac 56[/tex] yardsThe distance (d) between the oak tree and the maple tree is the difference between the above measurements.
So, we have:
[tex]d = 28\frac 26 - (11\frac 36 + 7\frac 56)[/tex]
Simplify the expression in the bracket

Find the 95th term of the arithmetic sequence 4, -5, -14
Answer: -842
Step-by-step explanation:
To find n95, we have to use the equation aₙ = d * n + a₁ - d
a₁ is the first term, which here is 4. d is the common difference, which we can find out but seeing what we can add pr subtract from 4 to -5 which also equals -5 to -14, in this equation, the common difference would be -9 as it goes down by 9 every term. Once we plug these into the equation, we get
a₉₅ = -9 * n + 4 - (-9)
We can solve this for - aₙ = -9n + 13
Now that we have our equation to find a term, we can plug in n for 95 for
-9(95) + 13
Which equals -842

Here is a system of linear equations
2x+3y=14
4x-3y=10
Which would be more helpful for solving the system: adding the two equations or subtracting one from the other?
Answer:
adding the 2 equations
Step-by-step explanation:
2x + 3y = 14 → (1)
4x - 3y = 10 → (2)
since the coefficients of the y- terms are opposites then adding will eliminate y
add (1) and (2) term by term
6x + 0 = 24
6x = 24 ( divide both sides by 6 )
x = 4
substitute x = 4 into either of the 2 equations and solve for y
substituting into (1)
2(4) + 3y = 14
8 + 3y = 14 ( subtract 8 from both sides )
3y = 6 ( divide both sides by 3 )
y = 2
solution is (4, 2 )
