The value of n will be:
[tex]n=\frac{89}{4}[/tex]Step-by-step explanation:
Given the expression
[tex]\frac{n}{2}-8^{-1}=11[/tex]
Apply the exponent rule:
[tex]a^{-1}=\frac{1}{n}[/tex]so the expression becomes
[tex]\frac{n}{2}-\frac{1}{8}=11[/tex]
Add 1/8 to both the sides
[tex]\frac{n}{2}-\frac{1}{8}+\frac{1}{8}=11+\frac{1}{8}[/tex]
[tex]\frac{n}{2}=\frac{89}{8}[/tex]
[tex]n=\frac{89}{4}[/tex]
Therefore, the value of n will be:

Answers
Answer:
a, b ,e
Step-by-step explanation:
The solutions to the equation f(x) = g(x) are x = -3.3 and x = 5.2
The correct answers are option (A) and option (E)
What is equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
What is solution to equations?"It is a value or a set of values, when substituted for the unknowns, the equation becomes true."
For given question,
We have been given the graph of a quadratic function f(x) and an absolute value function g(x).
We need to find the x-values that are approximate solutions to the equation f(x) = g(x).
To solve the equation f(x) = g(x), we look for the points where the graphs of f(x) and g(x) intersect.
The intersection point of f(x) = g(x) appears to be at point which lie in the second quadrant and the x-value lie between -2 and -4.
Also, the second intersection point lie in the fourth quadrant where x value is in between 4 and 6.
So, the solutions to the equation f(x) = g(x) are x = -3.3 and x = 5.2
The correct answers are option (A) and option (E)

There 18 rows of seats in the auditorium there are 24 seats in each row how many seats are in the auditorium
Answers
Answer:

Find the sum of the finite geometric series
6 - 4 + 8/3 - 16/9 + 32/17
Answers
Answer:
The sum of geometric series 6 - 4 + 8/3 - 16/9 + 32/17 is 4.0416
Step-by-step explanation:
We need to find the sum of geometric series 6 - 4 + 8/3 - 16/9 + 32/17
The formula used to find sum of geometric series is [tex]S_n=\frac{a(1-r^n)}{1-r}[/tex]
where a is 1st term, n is number of terms and r is common ratio
so, in the given geometric series 6 - 4 + 8/3 - 16/9 + 32/17 we have
First Term a=6
Common ratio r= -0.6
Number of terms n= 5
Putting values in formula to find sum of given geometric series
[tex]S_n=\frac{a(1-r^n)}{1-r}\\S_n=\frac{6(1-(-0.6)^5 )}{1-(-0.6)}\\S_n=\frac{6(1-(-0.07776))}{1+0.6}\\S_n=\frac{6(1+0.07776)}{1.6}\\S_n=\frac{6.46656}{1.6}\\S_n=4.0416[/tex]
So, the sum of geometric series 6 - 4 + 8/3 - 16/9 + 32/17 is 4.0416

Slope of Reflection line: 0.25
Equation of Reflection line: y = 0.25x - 2
Step-by-step explanation:
Slope of dotted line: rise/run. So 3/1 = 3. It is a negative slop because of the way it is facing ( \ ).
Slope of reflection line: rise/run. So 1/4 = 0.25. It is a positive slope ( / ).
Equation of reflection line: y = mx + b
m = slope
b = y-intercept
y = 0.25x - 2

Answer:
The answer is C)Spelling Scores vs. Hours Spent Studying
Step-by-step explanation:
This is the answer because if you look at all of the other options, then you will see that they have a steeper slope, you could also calculate and find for slope if u are still unsure :) hope this helps
The graph that has a trend line with the least slope is the History Scores vs. Hours Spent Studying graph
What is the slope of a line?The slope of a line is the quotient of the change in the vertical values to the corresponding horizontal values
Check below on how the trend line with the least slope can be determined
From the question, we have:
Line 1: (2.5, 60) and (3.5, 70)Line 2: (0.5, 40) and (3.5, 50)Line 3: (0.5, 80) and (4.5, 90).Line 4: (0.5, 50) and (2, 70).The slope (m) is calculated using:
m = (y₂ - y₁)/(x₂ - x₁)
So, we have:
m₁ = (70 - 60)/(3.5 - 2.5) = 10m₂ = (50 - 40)/(3.5 - 0.5) = 3.3m₃ = (90 - 80)/(4.5 - 0.5) = 2.5m₄ = (70 - 50)/(2 - 0.5) = 13.3The line 3 has the least slope
i.e. m₃ = 2.5
Hence, the graph that has a trend line with the least slope is the History Scores vs. Hours Spent Studying graph

Bob bought 5 books for x dollars each and a DVD for $12. Write an expression for how much money Bob spent.
Answers
Answer:
5x+12
Step-by-step explanation:
X symbolizes how many he is buying plus the extra 12 dollars
Answer:
5x+12=y
Step-by-step explanation:
Y represents the amount of money spent.
if x represents the amount of one book and Bob bought 5 books than you have to multiply the amount of one book by five to get the amount spent on all the books. Thus getting 5x
You need an equation to find how much money spent total. Thus adding $12 because Bob also bought a DVD for $12.
Therefore, the only logical equation is 5x+12=y
1. The Willis Tower (formerly known as the Sears Tower) in Chicago is about 1454 feet tall. A model of it has a scale of 2 in = 45 feet. How tall is the model?
Answers
Answer:
[tex]x\approx64.622\text{ inches}[/tex]
Step-by-step explanation:
We can write a proportion that relate the model lengths to the actual length. The traditional format is:
[tex]\frac{\text{Model Length}}{\text{Scale Factor}}=\frac{\text{Original Length}}{\text{Scale Factor}}[/tex]
Hence, we will substitute 1454 for the “Original Length.”
2in for the “Scale Factor” below the model.
And 45ft for the “Scale Factor” below the original.
Let the model length be x.
This yields:
[tex]\frac{x}{2}=\frac{1454}{45}[/tex]
Solve for x. Cross-multiply:
[tex]2908=45x[/tex]
Divide both sides by 45:
[tex]x\approx64.622\text{ inches}[/tex]
Therefore, the height of the model is about 64.6 inches.
Step-by-step explanation:
solution
we know that,
tower hight = 1454 feet
here
2inch=45 feet
now,
1454 feet=(1454/45)inch
1454 feet =32.31 inch
so,tower is 32.31 inch tall according to model length
