Answer:

I would recommend taking practice quizzes online for the level of math you are taking to find what areas you understand well and what areas you are struggling in. From there, you can review that specific area of math and refine your knowledge. Taking practice quizzes repeatedly until you are confident both in the mathematics and the test taking itself(if you struggle with test taking in general) will help a lot.

Answer:

Step-by-step explanation:

Study Time: I suggest you study over a period of time and try to understand the topic. For example, try to include breaks to help yourself relax. DO NOT cram lots of math into your head on an overnight studying marathon. Many people try that, and unless you have a photographic memory, it does not help at all.

Topics: Try to study one topic at a time so the information does not get mixed up in your head. Try to remember things with variables.

Resources: Ask your teacher what topics the test will cover and how many questions will be on the test. You can find lots of worksheets online and review explanations to similar questions on websites.

Morning before the test: Sleep early and wake up early. Try to relax and eat a healthy breakfast.

I wish you luck on your test!

Matrix is an arrangement of numbers into rows and columns. Make your first introduction with matrices and learn about their dimensions and elements. A matrix is a rectangular arrangement of numbers into rows and columns. For example, matrix A has two rows and three columns.

The augmented matrix in row-reduced form below is equivalent to the augmented matrix of a system of linear equations.

[ 1 0 0 0 | -9 ]

[ 0 1 1 0 | -8 ]

[ 0 0 0 1 | 1 ]

We find that this is a rectangular matrix 3 rows and 4 columns

i.e. the variables are four but independent equations are only 3.

So only parametric equations can be found out

First row gives x = -9

Last row gives w = 1

II row gives y + z =-8 and we do not have any other equation in y or z

Hence we have solution as:

z =z and y -8-z

The solution set is

x=9, y =-8-z, w =1, z=z

It should be noted that the addition of 1.17+ √63 will give an irrational number.

If p and q are integers and q is not equal to 0, then the number is in the form of p/q and is said to be rational. Among the rational number examples are 1/3, 2/4, 1/5, 9/3, and so forth.

All real numbers that are not rational numbers are referred to be irrational numbers in mathematics. In other words, it is impossible to describe an irrational number as the ratio of two integers.

In this case, the answer is irrational, as the square root of 63 is not a rational number and cannot be expressed as a fraction of two integers.

A scale factor is the ratio of the new object to a given original object.

For example,

The scale factor is A : B.

We have two similar trapezoid as shown in the picture.

Find (a) the scale factor from shape A to shape B, and (b) the value of w!

The scale factor from shape A to shape B can be determined by analyzing one of the side length. We can take the longest side of the trapezoid.

Scale factor = 9/12 = 3/4

The value of w side is correspond to 7. So,

w/7 = 3/4

The value of the angle 4 is 96 degrees as shown in the diagram.

A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Since lines can exist in two, three, or higher dimensional environments, they are one-dimensional things.

From the given diagram, the measure of angle 1 and 3 are equal as well as 2 and 4.

Given the following angles

m<3 = 84 degrees

Since the measure of <3 and <4 lies on the same straight line, hence:

m<3 + m<4 = 180

84 + m<4 = 180

What is supervised learning?

The use of labelled datasets distinguishes the machine learning strategy known as supervised learning. These datasets are intended to "supervise" or "train" algorithms to correctly classify data or forecast outcomes. Labeled inputs and outputs allow the model to monitor its precision and improve over time.

When using data mining, supervised learning may be divided into two categories: classification and regression.

Using an algorithm, classification issues correctly categories test data into distinct groups, such as distinguishing apples from oranges.

Describe verbally how modifying a and b changes the graph's form.

Here, Element X starts with 490 grams

After 1 year we have  (490 X 0.81 grams) or 396.9 grams

Now, We can solve for half-life by this equation:

Half life = (time  X log 2) / log (beginning amount / ending amount)

Half-life = (1 year X 0.30102999566) / log (490 / 396.9)

Half life = (1 year X 0.30102999566) / log (1.2345679012 )

Step-by-step explanation:

the distance from a vertex of the quadrilateral to the touching points on the two sides emanating from the vertex is the same.

and that applies to each of the 4 vertices.

so, AB splits into the distance a (from A to the circle touching point on AB) and b (from the touching point on AB to B).

b = AB - a

in the same way, BC splits into b (B to circle touching point on BC) = AB - a, and c (circle touching point on BC to C).

c = BC - (AB - a) = BC - AB + a

CD splits into c (C to circle touching point on CD) = BC - AB + a, and d (circle touching point on CD to D).

d = CD - (BC - AB + a) = CD - BC + AB - a

DA now splits into d (D to circle touching point on DA) = CD - BC + AB - a, and into ... a (the circle touching point on DA to A).

a = DA - (CD - BC + AB - a) = DA - CD + BC - AB + a

0 = DA - CD + BC - AB

DA = CD - BC + AB = 8 - 5 + 4 = 7

By using the x- and y-intercepts, a graph of the function modeling the total number of tickets sold is shown in the image attached below.

The domain and range of each function is {-∞, ∞}.

The meaning of the x-intercept is that the initial number of student tickets sold is 600 tickets.

The meaning of the y-intercept is that the initial number of adult tickets sold is 300 tickets.

The slope of the function is 0.5 and it represents the number of tickets sold per week.

You can use the graph to determine a combination of ticket sales to meet the goal of $3,000 by adding each ordered pair (s, a) or (x, y) together.

Felina's graph is correct because it has the same x-intercept and y-intercept with the original graph.

In order to write a linear equation to describe this situation, we would a assign variable to the number of student tickets sold and the adult tickets sold respectively, and then translate the word problem into a linear equation as follows:

Since student are paying $5 while adults are paying $10 for a ticket and the athletic association need to raise $3000 by selling tickets, a linear equation that models the situation is given by:

5s + 10a = 3000

When s = 0, the value of a is given by:

5(0) + 10a = 3000

a = 300

When a = 0, the value of s is given by:

5a + 10s = 3000

s = 600

For the total number of tickets, we have this linear equation:

s + a = 450

In conclusion, we would use an online graphing calculator to plot the system of linear equations in order to determine the solution (point of intersection), which is at the ordered pair (300, 150).

The percent rate of change of s(t) is approximately -26.15%. This means that the function is decreasing at a rate of about 26.15% per unit of time.

The function s(t) = 0.65[tex](0.48)^t[/tex]represents a decreasing exponential function, where t is time and s(t) is the value of the function at time t.

To find the percent rate of change of s(t) at any given time t, we can use the formula:

percent rate of change = [(new value - old value)/old value] x 100%

In this case, the "old value" is s(t) and the "new value" is s(t+1), or the value of the function one unit of time later.

So, the percent rate of change of s(t) is:

percent rate of change = [(s(t+1) - s(t))/s(t)] x 100%

We can substitute the given function into this formula:

percent rate of change = [(0.65[tex](0.48)^(t+1)[/tex]- 0.65[tex](0.48)^t)[/tex]/0.65[tex](0.48)^t][/tex]x 100%
