Explanation:
If we plugged x = 4 into the expression, then we'll have 0 in the denominator. This causes a division by zero error.
Luckily the numerator factors to (x-4)(x-2)^2. This is found by using the Rational Root Theorem, along with either synthetic division or polynomial long division. I'll skip these steps unless you need me to write them out.
Once we know the numerator factors this way, we can then write the following steps:
[tex]L = \displaystyle \lim_{\text{x}\to4}\frac{\text{x}^3-8\text{x}^2+20\text{x}-16}{\text{x}-4}\\\\\\L = \displaystyle \lim_{\text{x}\to4}\frac{(\text{x}-4)(\text{x}-2)^2}{\text{x}-4}\\\\\\L = \displaystyle \lim_{\text{x}\to4}(\text{x}-2)^2\\\\\\L = (4-2)^2\\\\\\L = 4\\\\\\[/tex]
Therefore,
[tex]\displaystyle \lim_{\text{x}\to4}\frac{\text{x}^3-8\text{x}^2+20\text{x}-16}{\text{x}-4}=4\\\\\\[/tex]

The function represented by the data in the table could
model the perimeter of a square whose area is x.
Explain how the function in the table models this
relationship. Be sure to identify how the function
represents area, perimeter, and the length of a side. Then
generalize the pattern in the table.
Type your response in the box.
Note that the pattern in the table is that the perimeter of a square with area x is four times the square root of x. We can express this relationship as:
f(x) = 4 * √(x)
What is the rationale for the above response?We know that the area of a square is calculated as the square of its side length, which means that the side length of a square with area x is the square root of x. Therefore, the length of the side of the square can be expressed as:
s = √(x)
To calculate the perimeter of the square, we simply add up the lengths of all four sides:
P = 4s = 4 * √(x)
So, the function f(x) in the table represents the perimeter of a square with area x, which can be calculated using the equation:
f(x) = 4 * √(x)
To verify this, let us take these examples:
when x = 1, the area of the square is 1, and the side length is 1. Therefore, the perimeter of the square is 4 * 1 = 4, which matches the value in the first row of the f(x) column.when x = 4, the area of the square is 4, the side length is 2, and the perimeter of the square is 4 * 2 = 8, which matches the value in the second row of the f(x) column, and so on.Learn more about Square Roots:

Find the values of x and y.
The value of x is 5, while the value of y is 24
How to solve for x and yIn order to get the value of x we would first have to find the value of y
The sum of angles on a straight line = 180
hence we would have:
5y + 2y + 12 = 180
7y = 180 - 12
7y = 168
y = 24 degrees
The angle that is made at R is 90 degrees
we would have
2y + 12 + 5x = 90
y = 24
2 * 24 + 12 + 5x = 90
60 + 5x = 90
5x = 90 - 60

Please help me with my following homework problem
The conclusion is that the mean bumper repair cost is greater for small pickups than for small utility vehicles at a significance level of 0.10.
How to make the decisionThe test statistic for this hypothesis test can be calculated as follows:
t = (μ1 - μ2) / sqrt(s1^2 / n1 + s2^2 / n2)
Plugging in the values, we get:
t = (1090 - 485) / sqrt(403^2 / 5 + 382^2 / 8) = 4.36
Next, we need to find the critical value for a two-tailed test at a significance level of 0.10 using a t-distribution table or using a t-distribution calculator.
Using a t-distribution table or calculator, we find the critical value for a two-tailed test at a significance level of 0.10 and df = 9.57 is ±1.833.
Since the calculated t-value (4.36) is greater than the critical value (1.833), we reject the null hypothesis and conclude that there is evidence to suggest that the mean bumper repair cost is greater for small pickups than for small utility vehicles at a significance level of 0.10.

The given expressions {4x^3+2x^2+6x+7}/{2x+1} and 2x^2+3+(4/{2x+1}) are equal at x = 10, they are not equal at x = -1/2, and they are equal for all x other than -1/2.
Substitute x = 10 in the given expressions, we get
{4x^3+2x^2+6x+7}/{2x+1}
= (4000+200+60+7)/21
=203.19
2x^2+3+(4/{2x+1}.)

The solution set for the inequality [tex]3(x+5)^3(x+4)^6(x+3)^3 > 0[/tex] is (-4, -3) ∪ (-3, ∞).
What is inequality?
An inequality is a mathematical statement that describes a relationship between two values or expressions, where one is greater than, less than, or not equal to the other.
To solve the inequality [tex]3(x+5)^3(x+4)^6(x+3)^3 > 0[/tex], we can use the concept of interval notation and test each interval to see if it satisfies the inequality. Here are the steps:
Find the critical points of the expression, which are the values that make the expression equal to zero. In this case, the critical points are -5, -4, and -3.
Use these critical points to divide the number line into four intervals: (-∞, -5), (-5, -4), (-4, -3), and (-3, ∞).
Test a value in each interval to see if the inequality is true or false. We can use the sign of the expression to determine this:
For x < -5, all three factors are negative, so the product is negative. Therefore, this interval does not satisfy the inequality.
For -5 < x < -4, the first factor is positive and the other two factors are negative. The product is therefore negative. This interval does not satisfy the inequality.
For -4 < x < -3, the first and third factors are positive and the second factor is negative. The product is therefore positive. This interval satisfies the inequality.
For x > -3, all three factors are positive, so the product is positive. Therefore, this interval satisfies the inequality.
Write the solution set using interval notation. We have found that the solution set is (-4, -3) union ( -3, ∞).
Therefore, the solution set for the inequality [tex]3(x+5)^3(x+4)^6(x+3)^3 > 0[/tex] is (-4, -3) ∪ (-3, ∞).

Provide your answer below:
Which option requires more interest to be paid over the life of the mortgage? How
Mortgage B requires $27,336.60 more interest than mortgage A. The solution has been obtained by using arithmetic operations.
What are arithmetic operations?
There are four fundamental mathematical operations that can be used to express any real number; these are referred to as "arithmetic operations." The four operations are multiplication, division, addition, and subtraction.
We are given the principal amount as $80,000.
So, interest on Mortgage A = Total amount payable - principal amount
Interest = $110,158.20 - $80,000
Interest = $30,158.20
Similarly, interest on Mortgage B = Total amount payable - principal amount
So,
Interest = $137,494.80 - $80,000
Interest = $57,494.80
So, difference in interest = $57,494.80 - $30,158.20 = $27,336.60
Hence, mortgage B requires $27,336.60 more interest than mortgage A.

b) Determine whether each sequence is arithmetic, geometric, or neither. Then find a formula for the n-th term of the sequence.

Answer:
Step-by-step explanation:
A) In a geometric sequence, t_(1)=625 and the common ratio is r=(1)/(5). For what value of n is t_(n)=(1)/(25)?
Step 1: Write the formula for the nth term
The formula for the nth term of a geometric sequence is t_n = t_1 * r^(n-1), where t_1 is the first term and r is the common ratio.
Step 2: Substitute the given values into the formula
t_n = 625 * (1/5)^(n-1)
Step 3: Solve for n when t_n = (1/25)
(1/25) = 625 * (1/5)^(n-1)
(1/25) / 625 = (1/5)^(n-1)
(1/5)^(n-1) = (1/25) / 625
(n-1) = log base (1/5) of ((1/25) / 625)
Step 4: Solve for n
n = 1 + log base (1/5) of ((1/25) / 625)
The value of n is the number of terms that have passed when t_n = (1/25).
B) (2)/(5),(3)/(6),(4)/(7),(5)/(8),...
Step 1: Determine the type of sequence
A sequence is an arithmetic sequence if the difference between any two consecutive terms is constant. Since this sequence does not have a constant difference, it is not an arithmetic sequence.
A sequence is a geometric sequence if the ratio between any two consecutive terms is constant. We can see that the ratio between any two consecutive terms is constant, so this sequence is a geometric sequence.
Step 2: Find the common ratio
To find the common ratio, we can divide any two consecutive terms. For example, the common ratio is (3/6) / (2/5) = (3/2) / (6/5) = 5/6.
Step 3: Write the formula for the nth term
The formula for the nth term of a geometric sequence is t_n = t_1 * r^(n-1), where t_1 is the first term and r is the common ratio.
Step 4: Substitute the given values into the formula
To use this formula, we need to know the value of t_1. We are given t_1 = (2/5), so:
t_n = (2/5) * (5/6)^(n-1)
This is the formula for the nth term of the sequence (2)/(5),(3)/(6),(4)/(7),(5)/(8),...
