How do you take the limit of this
The limit of the function lim x → ∞(x⁴ - 9x² + x)/(x³ - x + 6) is DNE
To take the limit of the function lim x → ∞(x⁴ - 9x² + x)/(x³ - x + 6), we proceed as follows
Since we have the function lim x → ∞(x⁴ - 9x² + x)/(x³ - x + 6) and we want to take the limit, we proceed thus,.
First, we divide both the numerator and denominator by x⁴. So,
lim x → ∞(x⁴ - 9x² + x)/(x³ - x + 6) = lim x → ∞(x⁴ - 9x² + x)/x⁴ ÷ (x³ - x + 6)/x⁴
= lim x → ∞(x⁴/x⁴ - 9x²/x⁴ + x/x⁴ ÷ (x³/x⁴ - x/x⁴ + 6/x⁴)
= lim x → ∞(1 - 9/x² + 1/x³ ÷ (1/x - 1/x³ + 6/x⁴)
Now, taking the limit as x tends to infinity, we have that
= lim x → ∞1 - lim x → ∞9/x² + lim x → ∞1/x³ ÷ lim x → ∞1/x - lim x → ∞1/x³ + lim x → ∞6/x⁴
= (0 - 9/∞² + 1/∞³)/(1/∞ - 1/∞³ + 6/∞⁴)
= (0 - 9/∞ + 1/∞)/(1/∞ - 1/∞ + 6/∞)
= (∞ - 0 + 0)/(0 - 0 + 0)
= (∞)/(0)

The equation of this type of line is y = kx. What is special about k?
Answer:
C
Step-by-step explanation:
k is the slope of the line
The equation of the line is y = kx. Therefore, the special thing about k is that it is the slope of the line.
Equation of a lineUsing a slope intercept equation,
y = kx + b
where
k = slope of the lineb = y-interceptTherefore, the y-intercept of the line y = kx is zero.
What is special about k is that it is the slope of the line y = kx.

William Right broke his leg in an accidental fall. He has a deductible of $150 and a coinsurance payment equal to 20% percent of the cost less the deductible. The entire bill for medical services was $750.00.
How much did William pay? $
How much did the insurance company pay? $
We know that William
paid his deductible that amount is the $150.
Then William paid 20 percent of everything else. That's 20 percent of (750
minus 150), it is equal to 150.
Then the insurance company paid 80 percent of (750 minus 250), it is equal to
480.
Answer:
its is he payed 270 and insurance payed 480
Step-by-step explanation:
just simply add up the numbers to 750 and the only ones that go together are 270 + 480 = 750 hope it helps :)

The rules of the order of operations tells you to multiply and divide in order from left to right.
What is multiplication?Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.
The order of operations can be remembered by the acronym PEMDAS, which stands for: parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right. There are no parentheses in this problem, so start with exponents. Then, multiply and divide from left to right.
Hence, the rules of the order of operations tells you to multiply and divide in order from left to right.

If I spoke with 800 customers in 40 hours how many customers did I speak to every 30 minutes
Answer:
10 customers were spoken to in every 30 minutes
Step-by-step explanation:
First, we convert 40 hours into minutes by multiplying it with 60 [as 1 hour = 60 minutes]
So, 40 hours = 40*60 minutes
= 2400 minutes
In 2400 minutes, number of customers served = 800
In 1 minute, number of customers served = [tex]\frac{800}{2400}[/tex]
In 30 minutes, number of customers served = [tex]\frac{800}{2400}*30[/tex]
= [tex]\frac{800}{2400} * \frac{30}{1}[/tex]
= [tex]\frac{800*30}{2400*1}[/tex]
= [tex]\frac{24000}{2400}[/tex]
= 10
So,
10 customers were spoken to in every 30 minutes
Final answer:
You spoke with 10 customers every 30 minutes.
Explanation:
To find out how many customers you spoke to every 30 minutes, we can set up a proportion. We know that you spoke with 800 customers in 40 hours, which is equivalent to 2400 minutes. So, the proportion is:
800 customers / 2400 minutes = x customers / 30 minutes
Now, we can cross-multiply and solve for x:
800 * 30 = 2400 * x
x = 800 * 30 / 2400
x = 10
Therefore, you spoke with 10 customers every 30 minutes.
You drove to your cousin's house, which is 460 miles away. After two hours, you had go e 100 miles. After 8 hours, you reached your destination. Write an equation that gives the number of miles you had driven, y, in germs of the number of hours you had driven, t.
To express the number of miles driven, y, in terms of the number of hours driven, t, we first find the speed and then use it to formulate the equation of the line as y = 60t. However, to accurately represent the entire trip, we must include the initial 100 miles driven in 2 hours, leading to y = 60t - 20 as the final equation.
To write an equation that gives the number of miles driven, y, in terms of the number of hours driven, t, we can use the relationship between distance and travel time. Given that after two hours you had gone 100 miles and after 8 hours, you reached your destination, which is 460 miles away, we establish two points on our distance-time graph: (2, 100) and (8, 460).
Using the two points, we can find the slope of the line, which represents the speed:
Slope (speed) = (change in distance) / (change in time) = (460 - 100) miles / (8 - 2) hours = 360 miles / 6 hours = 60 miles/hour.
We can now express the equation of the line as y = mx + b, where m is the slope and b is the y-intercept. The y-intercept represents the distance at time zero, which for most driving scenarios we assume to be 0 miles. Thus, the equation becomes y = 60t. However, this equation would not accurately represent the entire trip since it doesn't account for the initial 100 miles driven in the first 2 hours.
To adjust for that, we'll introduce an offset for the initial 100 miles traveled in the first 2 hours. The y-intercept would be 100 miles less than if we had started from 0 miles at 0 hours. The corrected equation for the entire trip would be of the form y = 60t + b, where b = y - 60t and y are the miles covered in the initial 2 hours, which is 100 miles. Substituting the values, we get b = 100 - 60 x 2 which equals -20.
The final equation, accounting for the first 2 hours of travel, would therefore be: y = 60t - 20.
if you flip the graph of the exponential function f(x)=2x over the x axis what is the equation of the new function
Answer:
Option: B is the correct answer.
The equation of the new function g(x) on flipping the function f(x) over the x-axis is:
[tex]g(x)=-2^x[/tex]
Step-by-step explanation:
We are given a graph of the exponential function f(x) which is represented by:
[tex]f(x)=2^x[/tex]
We know that when a graph of a function is reflected or flipped over the x-axis then the the change that take place to the function is that f(x) is transformed to -f(x).
( Since on flipping the function over the x-axis the positive value of the function get changed to negative and the negative value of the function is changed to positive)
Hence, the equation for the new function is:
[tex]g(x)=-f(x)\\\\g(x)=-2^x[/tex]
Write the equation of the line containing the point (3, –2) and having a slope of 2 in slope-intercept form.
The equation of a line containing the point (3, –2) and having a slope of 2, is y = 2x-8
What is an equation of a line?The general equation of a line in two variables of the first degree is represented as Ax + By +C = 0, A, B ≠ 0 where A, B and C are constants which belong to real numbers. When we represent the equation geometrically, we always get a straight line.
Given that a line containing the point (3, –2) and having a slope of 2, we need to find the equation of the line,
So, the general equation of a line is y = mx+c
Where, m is the slope and c is the y-intercept.
Therefore,
y = 2x+c
Now, put x = 3 and y = -2 in the equation to find the value of c,
-2 = 3(2)+c
-2 = 6+c
c = -8
Put the value of c in the equation,
y = 2x-8
Hence, the equation of a line containing the point (3, –2) and having a slope of 2, is y = 2x-8

To find : Which is the equation of the line.
Solution : we have given that point ( -5 ,4)
By equation of line ([tex]y-y_{1}) = m (x -x_{1})[/tex]
