Astrid says the function being graphed is y=-4+1/3
. She says that her equation is correct because the slope of the line is -4.
Matt says the function that is being graphed is y=1/3x
. He says that the slope of the line is actually 1/3
Is Astrid correct? Is Matt correct? Explain your reasoning
If Astrid says the function being graphed is y=-4+1/3. Matt is correct, while Astrid is incorrect.
How to find if Matt or Astrid is correct?Astrid's equation y = -4 + 1/3 is incorrect because it is missing the variable x. The equation is missing a term that represents the x variable, so the equation does not represent a line.
On the other hand, Matt's equation y = 1/3x is correct, and the slope of the line represented by this equation is indeed 1/3. This can be seen from the fact that the equation is in the form y = mx, where m is the slope of the line. In this case, m = 1/3, so Matt is correct.
Therefore, Matt is correct, while Astrid is incorrect.

Find the slope of the following line:
x = 5
Answer:
The equation x = 5 represents a vertical line passing through the point (5, 0) on the x-axis. A vertical line has an undefined slope because the rise (change in y) is undefined when the run (change in x) is zero. Therefore, the slope of the line x = 5 is undefined.

⦁ What is the product of -2^3 + x - 5 and x^3 -3x +4 ?
⦁ Show your work.
⦁ Is the product of -2^3 + x - 5 and x^3 -3x +4 equal to the product of x^3 -3x +4 and -2^3 + x - 5 ? Explain your answer.
The product of -2³ + x - 5 and x³ -3x +4 is -5x³ + 16x - 28.
How did we get the value?The given expression is:
-2³ + x - 5 x (x³ -3x +4)
We need to follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
First, let's simplify -2³, which means -2 x 2 x 2 = -8, so we have:
-8 + x - 5 x (x³ -3x +4)
Next, we need to distribute the -5 to the terms inside the parentheses:
-8 + x - 5x³ + 15x - 20
Now we can combine like terms:
-5x³ + 16x - 28
Therefore, the product of -2³ + x - 5 and x³ -3x +4 is -5x³ + 16x - 28.
Now, to answer the second part of the question, we need to check if:
-2³ + x - 5 x (x³ -3x +4) = (x³ -3x +4) * (-2³ + x - 5)
We can simplify both expressions first:
-8 + x - 5x³ + 15x - 20 = -8 + x - 5x³ + 15x - 20
We can see that both expressions are identical, which means that the product of -2³ + x - 5 and x³ -3x +4 is equal to the product of x³ -3x +4 and -2³ + x - 5, regardless of the order in which we multiply the factors.

The percent increase in the amount of interest paid between a household with a 780 credit score and one with a 589 credit score is approximately 0.8%, which is closest to option B, 0.8% or 39.9%.
Finding the entire amount paid by each family and comparing the difference in total amount paid will allow us to determine the percentage rise in the amount of interest paid between a household with a credit score of 780 and one with a score of 589.
The overall cost for a FICO score of 780 is:
$12,650 for the principal balance and all installments plus (33 x $60) to get $14,930.
With a 589 FICO score, the total cost is:
Total payments plus principal balance equal $12,650 plus (40 x $60) = $15,050.
The two households' combined total outlays differ in the following ways:
$15,050 - $14,930 = $120
We multiply by 100 and divide the difference by the initial sum to determine the percent increase:
($120 / $14,930) x 100% = 0.802% ≈ 0.8%
In light of this, the difference in interest rates between a family with a 780 credit score and one with a 589 credit score is roughly 0.8%, which is closest to option B, 0.8% or 39.9%.

A manufacturer knows that their items have a normally distributed length, with a mean of 9.8
inches, and standard deviation of 2 inches.
If 17 items are chosen at random, what is the probability that their mean length is less than 10.9
inches?
As a result, the likelihood that the mean length of a random sample of 17 items is less than 10.9 inches is about 0.9265, or 92.65%.
What exactly is probability?Probability is a measure of how likely an event is to occur. It is a number between 0 and 1, with 0 suggesting that an occurrence is impossible and 1 indicating that an event is unavoidable. A given event's probability is computed by dividing the number of positive outcomes by the total number of potential possibilities.
In this case, we may utilize the central limit theorem to estimate the sample mean distribution. The central limit theorem states that if the sample size is high enough (n 30), the distribution of the sample mean will be normal.
Regardless of demographic distribution, the population is essentially typical.
In this scenario, the population has a normal distribution with a mean () of 9.8 inches and a standard deviation () of 2 inches. We wish to calculate the likelihood that the sample mean (x) of 17 objects is smaller than 10.9 inches.
The formula for calculating a sample mean's z-score is: z = (x - ) / ( / sqrt(n)), where n is the sample size.
We obtain: z = (10.9 - 9.8) / (2 / sqrt(17)) by substituting the numbers supplied in the problem.
z = 1.45
We may calculate the chance that a standard normal variable is smaller than 1.45 using a typical normal distribution table or calculator:

Answer:
C) 260 square inches.
Step-by-step explanation:
To find the surface area of a pyramid, we can use the formula.
Surface Area = (1/2) x Perimeter of Base x Slant Height + Base Area
where l is the length of one side of the square base, s is the slant height, and Base Area is the area of the square base.
In this case, the base of the pyramid is a square with side length l = 10 inches, so its area is
Base Area = l^2 = 10^2 = 100 square inches
To find the perimeter of the base, we can simply multiply the length of one side by 4
Perimeter of Base = 4l = 4 x 10 = 40 inches
We are also given that the slant height of the pyramid is s = 8 inches.
Now we can substitute the values into the formula.
Surface Area = (1/2) x Perimeter of Base x Slant Height + Base Area
Surface Area = (1/2) x 40 x 8 + 100
Surface Area = 160 + 100
Surface Area = 260 square inches
Therefore, the surface area of the pyramid is 260 square inches.

Let r(x) = f(g(h(x))), where h(1) = 3, g(3) = 4, h'(1) = 3, g'(3) = 4, and f '(4) = 5. Find r'(1).
The value of r'(1) = 60 for the given function, using the chain rule.
What are derivatives of composite function?By adding the derivatives of f(x) with regard to g(x) and g(x) with respect to the variable x, one may get the derivative of the composite function h(x) = f(g(x)). The chain rule of differentiation can be used to derive derivatives of composite functions. Now, let's go over what composite functions are. When a function is expressed in terms of another function, it is said to have a composite function. This suggests that a function can be changed into another function in a composite function.
Using the chain rule of derivatives we have:
r'(x) = f'(g(h(x))) * g'(h(x)) * h'(x)
Substituting the values we have:
r'(1) = f'(g(h(1))) * g'(h(1)) * h'(1)
r'(1) = f'(g(3)) * g'(3) * 3
r'(1) = f'(4) * 4 * 3
r'(1) = 5 * 4 * 3
r'(1) = 60
Hence, the value of r'(1) = 60 for the given function, using the chain rule.

Write an equation parallel to each of the following:
Please help!!!!
find the critical points and critical values of the function z=x^3+6xy-y^3-1
Answer:
∂z/∂x = 3x^2 + 6y
∂z/∂y = 6x - 3y^2
Now, we need to solve the system of equations:
3x^2 + 6y = 0
6x - 3y^2 = 0
From the first equation, we get:
y = -x^2/2
Substituting this into the second equation, we get:
6x - 3(-x^2/2)^2 = 0
Simplifying, we get:
6x - 3x^4/4 = 0
Multiplying by 4 and rearranging, we get:
3x^4 - 24x = 0
Factoring out 3x, we get:
3x(x^3 - 8) = 0
Therefore, the critical values of x are x = 0 and x = 2.
For x = 0, we have y = 0 (from y = -x^2/2). So, one critical point is (0, 0).
For x = 2, we have y = -2. So, the other critical point is (2, -2).
To find the critical values of the function, we need to evaluate the function at each critical point:
z(0, 0) = 0^3 + 6(0)(0) - 0^3 - 1 = -1
z(2, -2) = 2^3 + 6(2)(-2) - (-2)^3 - 1 = -13
Therefore, the critical values of the function are -1 and -13.

B) 3 years
C) 7 years
D) 8 years
Using the equation, A = 6,000(1+0.029t) The number of years that is the investment period is: D 8 years.
How to Calculate Investment Period?Investment period refers to the length of time during which an individual or organization invests money in a particular investment vehicle or asset. It can also be referred to as the holding period, and it is the duration for which an investment is held or maintained before it is sold or liquidated.
We can start by setting the equation for the final account balance, A, to $7,392:
7,392 = 6,000(1 + 0.029t)
Divide both sides by 6,000:
1.232 = 1 + 0.029t
Subtract 1 from both sides:
0.232 = 0.029t
Divide both sides by 0.029:

If x is the average of m and 9, y is the average of 2m and 15, and z is the average of 3m and 18, what is the average of x, y, and z in terms of m
Answer: To find the average of x, y, and z in terms of m, we first need to find expressions for x, y, and z in terms of m:
x = (m + 9)/2
y = (2m + 15)/2
z = (3m + 18)/3 = (m + 6)
To find the average of x, y, and z, we add them up and divide by the number of terms:
average = (x + y + z)/3
Substituting the expressions for x, y, and z, we get:
average = [(m + 9)/2 + (2m + 15)/2 + (m + 6)]/3
Simplifying the expression by combining like terms, we get:
average = (4m + 30)/6
Simplifying further by dividing both the numerator and denominator by 2, we get:
average = (2m + 15)/3
Therefore, the average of x, y, and z in terms of m is (2m + 15)/3.
