Answer:

Step-by-step explanation: The graph is vertically stretched by a scale factor of 0.5 and shifted up 3 units.

Here we need to explain what the two transformations applied to f(x) do, and then we also can see it graphically.

we can see that we have a vertical stretch of scale factor k = 0.5 followed by a vertical shift of 3 units upwards.

Now let's explain how we know that.

The two transformations applied are:

Vertical stretch:

For a given function f(x) we write a vertical stretch of scale factor as:

g(x) = k*f(x).

Which stretches or contracts the graph vertically, depending on the value of k.

Vertical shift.

For a function f(x) a vertical shift of N units is written as:

g(x) = f(x) + N

So here we have:

g(x) = 0.5*f(x) + 3

Comparing with the general transformations, we can see that we have a vertical stretch of scale factor k = 0.5 followed by a vertical shift of 3 units upwards.

The two functions are:

f(x) = |x|

g(x) = 0.5*|x| + 3

The graphs can be seen below, where the blue one is the graph of g(x), the transformed function.

The probability that the students will have a pop quiz on a randomly selected day is 0.77, or 77%.

Probability is a measure of the likelihood of an event occurring. In mathematics, probability is usually defined as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. For example, the probability of rolling a six on a fair six-sided die is 1/6, or approximately 0.167.

The concept of probability is used to describe random phenomena, such as the outcomes of a coin toss or the weather forecast. Probability theory provides a framework for calculating the probabilities of various events, based on certain assumptions and rules.

To find the probability that the students will have a pop quiz on a randomly selected day, we need to use the law of total probability and consider both cases: when Mrs. Barnes checks homework and when she does not check homework.

The probability of having a pop quiz on a randomly selected day can be calculated as:

P(pop quiz) = P(checks homework) * P(pop quiz | checks homework) + P(does not check homework) * P(pop quiz | does not check homework)

Substituting the given probabilities, we get:

P(pop quiz) = 0.42 * 0.6 + 0.58 * 0.9

P(pop quiz) = 0.252 + 0.522

P(pop quiz) = 0.774

Therefore, the probability that the students will have a pop quiz on a randomly selected day is 0.77, or 77%.

Answer:

\(8*8*8*8*3*3= 8^4 * 3^2\)

Step-by-step explanation:

The exponents are used to write mathematical expressions in compact and simple form which is called scientific notation.

Given expression is:

\(8*8*8*8*3*3\)

When two or more same numbers are multiplied they can be written using exponents. i.e. a*a*a = a^3

We can see that 8 is repeated four times in the expression so,

\(8*8*8*8 = 8^4\)

Similarly, 3 is repeated two times

\(3*3 = 3^2\)

Combining both we get

\(= 8^4 * 3^2\)

Hence,

\(8*8*8*8*3*3= 8^4 * 3^2\)

Answer:

7x^3 + 2x^2 - x

Step-by-step explanation:

To subtract the two expressions (9x^3-4x^2+2x) and (2x^+6x^2-3x), we will need to line up the terms with the same exponent and subtract them.

(9x^3-4x^2+2x) - (2x^+6x^2-3x)

= (9x^3 - 2x^3) + (-4x^2 + 6x^2) + (2x - 3x)

= 7x^3 + 2x^2 - x

So the result of the subtraction is 7x^3 + 2x^2 - x

Please note that if you want to simplify the result further, you can combine like terms.

Both expressions equal 5 when substituting 2 for x because the expressions are equivalent.

Algebra is the branch of mathematics that deals with numbers and values which are represented with letters and symbols.

Sometimes, we do not want to mention a particular number, we can represent the number by a letter or a suitable symbol. This approach is algebraic.

For example, d + d = 2d

This is an example of an algebraic expressionns.

Given the algebraic expressions,

cos(xº)

Changing the degree into radian, we have

cos(xπ/180)

Answer:

The downtown angle measures about 22.62° and the town pool angle measures about 67.38°.

The hypotenuse measures 13 miles. Each third measures 4 1/3 miles.

Step-by-step explanation:

Use trigonometric ratios to solve this problem.

a. Find the measure of each acute angle of the right triangle shown.

Let's start with the acute angle that's marked near downtown. We can use the trigonometric ratio tangent to find the measure of this angle. (Remember, tangent = opposite/adjacent!)

We can divide the opposite side from the angle by the adjacent side to find the tangent:

5/12

= 0.4166666...

Now, we do the inverse tangent to find the measure of the angle:

≈ 22.62°

Now, we can find the angle near the town pool. This time, we can use tangent again, but the 12 mi side is the opposite and the 5 mi side is the adjacent:

12/5

= 2.4

Now, calculate the inverse tangent:

≈ 67.38°

b. Find the length of the hypotenuse. Also find the length of each of the three congruent segments forming the hypotenuse.

We can use the Pythagorean theorem to find the length of the hypotenuse. Remember, given legs a and b and hypotenuse c, the Pythagorean theorem states:

a² + b² = c²

Plug the values in this triangle into this equation:

5² + 12² = c²

25 + 144 = c²

169 = c²

13 = c

The hypotenuse measures 13 miles.

Now, we find the length of the three congruent segments that form the hypotenuse. (to be honest, I'm not sure that there are three congruent segments, but oh well, I'll just go with what it says there).

Since all the segments are the same length, we can just divide 13 by 3 to find the length of each of them:

13/3 = 4 1/3.

Each of the segments measures 4 1/3 miles.
