Answer:

A

Step-by-step explanation:

Given a parabola in standard form, y = ax² + bx + c ( a ≠ 0 ), then

minimum/ maximum value is the y- coordinate of the vertex.

The x- coordinate of the vertex is

\(x_{vertex}\) = - \(\frac{b}{2a}\)

y = x² - \(\frac{5}{3}\) x + \(\frac{31}{36}\) ← is in standard form

with a = 1 and b = - \(\frac{5}{3}\) , thus

\(\frac{x}{vertex}\) = - \(\frac{-\frac{5}{3} }{2}\) = \(\frac{5}{6}\)

Substitute this value into y

y = (\(\frac{5}{6}\) )² - \(\frac{5}{3}\) (\(\frac{5}{6}\) ) + \(\frac{31}{36}\)

   = \(\frac{25}{36}\) - \(\frac{25}{18}\) + \(\frac{31}{36}\) = \(\frac{1}{6}\)

Since a > 1 then the vertex is a minimum, thus

minimum value = \(\frac{1}{6}\) → A

Step-by-step explanation:

=92

Answer: About 9.68

2.9 ^ (x + 10) + 3 - 3 = 92 - 3

2.9 ^ (x + 10) = 89

Next, we'll take the logarithm base 2.9 of both sides:

log2.9 (2.9 ^ (x + 10)) = log2.9 89

x + 10 = log2.9 89

Finally, we'll solve for x:

x = log2.9 89 - 10

x ≈ 9.68.

Reason:

Vertical angles form after intersecting two lines in an X shape. The vertical angles are opposite one another. They do not have to be vertically aligned.

The other pair of vertical angles are ADB and XDF.

Vertical angles are always congruent.

The problem statement as given is y - 3x = 1y.  That's a little strange because we could subtract y from both sides of the equation and y would disappear completely, leaving us with -3x = 0.

Perhaps the correct problem statement is y - 3x = 1.  This is just a guess and so could be wrong.  But it allows us to look at how to solve similar problems.  

I suggest putting the problem into standard slope-intercept form.  That's a good idea when answering questions involving slopes.  Slope-intercept form means working on the equation to get it into a form that shows y = mx + b, where m is the slope and b is the intercept.

To do this for our equation, we can add 3x to both sides of the equation to get y = 3x + 1.  We note that our slope is 3 since 3 is the coefficient on the x term when the equation is put into standard slope-intercept form.

All lines parallel to this line must have the same slope.  So, all parallel lines will have a 3x term when put in standard slope-intercept form.  The only answer that meets that requirement is D. y = 3x + 2.

The missing values are:

BC = 25, BN = 16, NC = 9, and AN = 12

Given:

AB = 20

AC = 15

Using the Pythagorean theorem in triangle ABC:

CB = √AC² + AB²

CB= √20² + 15²

CB= √625

CB= 25

Since, AN is altitude we have ΔNBA~ΔABC and ΔNAC~ΔABC

BN / AN = BA / CB

BN/ 20= 20/25

BN = 16

and, AN / BA = AC / CB

AN /20 = 15/ 25

AN = 12

Now, CN=  CB - BN

CN = 25- 16

CN= 9

BC^2 = 20^2 + 15^2

BC^2 = 400 + 225

Since ΔANC is a right triangle so

AN = √15²-12²

AN = √81

AN = 9

The order of events from least likely to most likely are as follows:

The reason for this order is because of the chances of each event occurring. Event D has the least chance of occurring because no numbers in the set have a value less than or equal to 0. Event A is the next least likely because only one number in the set is greater than 0, which is the number 1. Event C is the next least likely because only two numbers in the set are at least 2 (2 and 3). Event B is the next least likely, as there are only five even numbers in the set (2, 4, 6, 8, and 10). Events E, F, G, and H are the most likely to occur, because of the number of numbers that are divisible by 3, and 5, and are prime numbers.

The area under the curve of the function f(x) between the points x = 1 and x = 5 is equal to 6 units.

Given that f is a continuous function and ∫1 5 f(x)dx = 6, we know that the area under the curve of f between 1 and 5 is equal to 6.

We don't have any information about g, so we can't say much about it. However, we can use the fact that f is continuous to make some deductions.

Since f is continuous, we know that it must be integrable on [1, 5]. This means that we can define another function F(x) as the definite integral of f(x) from 1 to x:

F(x) = ∫1 x f(t) dt

We can then apply the fundamental theorem of calculus to F(x) to get:

F'(x) = f(x)

In other words, F(x) is an antiderivative of f(x), so its derivative is f(x).

We can also use the fact that f is continuous to say that it must have an average value on [1, 5]. This average value is given by:

avg(f) = (1/4) ∫1 5 f(x) dx

Using the fact that ∫1 5 f(x)dx = 6, we can simplify this to:

avg(f) = (1/4) * 6 = 1.5

This means that on average, the value of f(x) between 1 and 5 is 1.5.

However, since we don't know anything else about f, we can't say much more than that.


Based on the given information, f and g are continuous functions and the definite integral of f(x) from 1 to 5 is equal to 6. In mathematical notation, it can be expressed as:

∫(from 1 to 5) f(x)dx = 6

Gross margin is calculated by subtracting the cost of goods sold from the total revenue.

To understand this calculation more comprehensively, let's break it down:

1. Total Revenue: Total revenue represents the total amount of money generated from the sales of goods or services.

It includes the selling price of the products or services and any additional income related to sales, such as shipping charges or discounts.

2. Cost of Goods Sold (COGS): Cost of Goods Sold refers to the direct costs incurred in producing or acquiring the goods that were sold.

It includes expenses such as the cost of raw materials, manufacturing costs, labor costs directly associated with production, and any other expenses directly tied to the production of goods.

By subtracting the COGS from the total revenue, we arrive at the gross margin, which represents the amount of money remaining after accounting for the direct costs associated with the production or acquisition of the goods sold.

Gross margin reflects the profitability of the core business operations before considering other indirect expenses such as overhead costs, marketing expenses, or administrative costs.

The formula for calculating gross margin can be represented as follows:

Gross Margin = Total Revenue - Cost of Goods Sold

Primarily, horizontal lines mean zero slope. Therefore the equation is y= 3 because you are only left with the y-intercept at this point. The rate of change is another way of saying slope. Function 2's slope is 5 and function 1's slope is 0. Therefore, the rate of change of function 2 is greater than the rate of change of function 1 by 5.

6 x 6 is 36. 3 x 2 is 6. 36 + 6 is 42.

Option 2 is correct - g(x) = x^3 function  has an inverse.

For a function to have an inverse, it must be One-to-One.

for f(x)= x^2

f(-1) = (-1)^2

= 1

and f(1) = (1)^2

=1

i.e x1 does not equal to x2 but f(x1) = f(x2)

Therefore the function is not One-to-One. So, it doesn't have an inverse.

for g(x) = x^3

g(-1) = (-1)^3

= -1

and g(1) = (1)^3

= 1

i.e x1 does not equal to x2 and g(x1) is not equal to g(x2).

Therefore the function is One-to-One . So, it has an inverse.

so y= g(x) = x^3

the inverse is y^-1 = g^-1(x) = x^1/3.

The Wald test is a statistical test that can be used to test the significance of a group of coefficients in a multiple regression model.

The test statistic is calculated as the ratio of the estimated coefficient to its standard error. If the test statistic is significant, then the null hypothesis that the coefficient is equal to zero can be rejected.

Suppose we have a multiple regression model with three independent variables: age, gender, and education. We want to test the hypothesis that the coefficients for age and education are both equal to zero. The Wald test statistic would be calculated as follows:

Test statistic = (Estimated coefficient for age) / (Standard error of estimated coefficient for age) + (Estimated coefficient for education) / (Standard error of estimated coefficient for education)

If the test statistic is significant, then we can reject the null hypothesis that the coefficients for age and education are both equal to zero. This would mean that there is evidence that age and education are both associated with the dependent variable.

The Wald test is a powerful tool that can be used to test the significance of a group of coefficients in a multiple regression model. However, it is important to note that the test statistic is only valid if the assumptions of the multiple regression model are met. If the assumptions are not met, then the p-value of the Wald test may be inaccurate.

Here are some of the assumptions of the multiple regression model:

* The independent variables are independent of each other.

* The dependent variable is normally distributed.

* The errors are normally distributed.

* The errors have constant variance.

If any of these assumptions are not met, then the Wald test may not be accurate.
