C. g(x) = (x+3)2 +5(x + 3) - 1
D. g(x) = (x-3)2 + 5(x-3) -1

Answers

Answer:

D

Step-by-step explanation:

When a function is being shifted to the left, all x values will be added by y units shifted. (The constant that comes with x is excluded, eg. 3x shifted by 2 units left, becomes 3(x+2) and not 3x+2.)

Likewise, when a function is being shifted to the right, all x values will be subtracted by y units shifted. (Constant rules applies as well.)

Given f(x) is shifted 3 units right,

the new function, g(x) becomes:

[tex] g(x) = {(x - 3)}^{2} + 5(x - 3) - 1[/tex]

Therefore the answer is D in this case.

A scale drawing of a house addition shows a scale factor of 1 in. = 3.3 ft. josh decides to make the house addition smaller, and he changes the scale of the drawing to 1 in. = 1.1 ft. what is the change in the scale factor from the old scale to the new scale? one-third two-thirds 2.2 3

Answers

3 is the scale factor that was changed from the previous scale to the new scale.

What is  the scale factor?

The scale factor is a way to compare figures that appear to be similar but actually have distinct scales or measurements. Let's say two circles have similar appearances but different radii. A figure's scale factor indicates how much larger or smaller it is than the original figure.

What is the change in the scale factor?

A scale drawing is a condensed representation of an original image, structure, or object in terms of dimensions. The scale drawing is typically shrunk at a fixed dimension.

The change in the scale factor = larger scale / smaller scale

3.3 / 1.1 = 3

The end behavior of the given function (range) is x< 4 or x > 4. So, f(x) < 4 or f(x) > 4. The solution in interval notation is [tex]\mathbf{(-\infty, 4) \cup (4, \infty)}[/tex].

The last option is correct.

What is the range of the function?

The end behavior of the given function f(x) = (8x+1)/2x-9 wants us to identify the range of the given function.

The range is the set of values of the dependent variable for which a function is defined. The function range is the combined domain of the inverse function.

From the information given:

[tex]\mathbf{f(x) = \dfrac{8x +1}{2x -9 }}[/tex]

Inverse of [tex]\mathbf{\dfrac{8x +1}{2x -9 }}[/tex] becomes [tex]\mathbf{f(x) = \dfrac{1+9x}{2(-4+x) }}[/tex]

The domain of the inverse is x< 4 or x > 4. So, f(x) < 4 or f(x) > 4. Now, representing the solution in interval notation, we have:

Quadratic formula for ax^2 + bx + c = 0  is

Here we have a = 5, b = -6 and c = -2

so x =  [-(-6)  ± √((-6)^2 - 4*5*-2)]/ 2*5

=  [ 6 ± √(36 + 40)] / 10

= 0.6 ±  √76 / 10

x^2 + 3x = 40

x^2 + 3x - 40 = 0

If either a or b equals zero, then the sums would be the same.

Since the square root of 0 is 0, adding it to a given radical would not change the radical. Also, adding zero to the radicand would not change its value.

The statement √a + √b = √(a + b) is not possible since a ≠ b

How to determine whether or not the statement is true?

The operation involving surd is most likely an algebraic expression where in the case of surd the value in the square root are like the alphabets in algebraic expression.

Some surd operations are given as shown below:

√a + √a = 2√a√a × √a = a2√a + √a = (2 + 1)√a = 3√a3√a - 2√a = (3 - 2)√a = √a√a × √b = √(a × b) = √(ab)√a + √b = √a + √b

Now, let us consider the question given:

a ≠ b√a + √b = √(a + b)

Since a and b are not equal, it means

√a + √b ≠ √(a + b)

Thus, we can conclude that the statement √a + √b = √(a + b) is not possible

Answers

The value of z in the given figure of circle with two lines dividing it into segments is 100.

We are given that the measures of angles ∠1 and ∠2 are 105° and 120°, respectively.

Step 1: Since the interior angles of a triangle add up to 180°, we know that the measure of ∠3 is 180° - 105° - 120° = 55°.

Step 2: Since ∠3 and ∠z are supplementary angles, we know that m∠3 + m∠z = 180°.

Step 3: Substituting the measures of ∠3 from step 1 into step 2, we get 55° + m∠z = 180°.

Step 4: Subtracting 55° from both sides of the equation in step 3, we get m∠z = 180° - 55° = 125°.

Step 5: Since m∠z = 125°, then z = 125°.

Therefore, the value of z is 100.

Considering the definition of an inequality, the number of friends admitted must be less than or equal to 8, expressed as p ≤ 8

Definition of inequality

An inequality is the existing inequality between two algebraic expressions, connected through the signs:

greater than >.less than <.less than or equal to ≤.greater than or equal to ≥.

An inequality contains one or more unknown values ​​called unknowns, in addition to certain known data.

Solving an inequality consists of finding all the values ​​of the unknown for which the inequality relation holds.

Inequality in this case

In this case, you know that:

A group of friends have no more than $325 to spend on parking and admission. Parking is $11Tickets cost $39.25 per person, including tax.

Being "p" the maximum number of people who can go to the amusement park, the inequality that expresses the previous relationship is

39.25 p + 11 ≤ 325

Solving:

39.25 p ≤ 325 -11

39.25 p ≤ 314

p ≤ 314÷ 39.25

p ≤ 8

Finally, the number of friends admitted must be less than or equal to 8, expressed as p ≤ 8

With the 10th payment, the borrower pays an extra 1,000, and then repays the balance over 10 years with a revised annual payment. The effective rate of interest is 8%. Calculate the amount of the revised annual payment. PLSSSSSS HELP PLS!!!!!Booker T. Washington wrote about education in 1899. The Supreme Court's decision inBrown vs. Board of Education was made in 1954. Based on the information in thepassages, compare the state of education for black children at these two points inAmerican history. Use details from both passages to support your answer 5. explain when donated materials should be recognized as a contribution and as an expense by a not-for-profit organization. Which of the following best describes the means by which most of those people leaving death row since 1976 have left?a. Most were executed.b. Most received clemency.c. Most died from causes other than execution.d. Most had their sentence or conviction overturned by an appeals or higher court. A die is selected at random from an urn that contains two six-sided dice. Die number 1 has three faces with the number 3, while one face each has the numbers 1, 2, and 4. Die number 2 has three faces with the number 2, while one face each has the numbers 1, 3, and 4. The first five rolls of the die yielded the numbers 1,3,3,2, and 4, in that order. Determine the probability that the selected die was die number 2.

CVP analysis Describe a walk along the number line that (a) is unbounded, and (b) visits zero an infinite number of times. Does a series corresponding to this walk converge? An ideal gas undergoes a spontaneous expansion at constant temperature. During this process, its entropy __________Select the correct answer:a) decreases.b) remains unchanged.c) increases.d) cannot be predicted from the data given Explain how delta T would be affected if a greater amount of surrounding solvent (water) is used, assuming the mass of salt remains constant? b. Explain how q_reaction would be affected if a greater amount of surrounding solvent (water) is used? Explain. If the following enthalpies are known: A + 2B rightarrow 2C + D delta H = -95 kJ B + X rightarrow C delta H = +50kJ What is delta H for the following reaction? A rightarrow 2X + D Brodifacoun is a rat poison with a LD50 = 0.35 mg/kg. It is mixed into rat bate (50mg/kg). How much rat bait (in kg) would be needed to reach the LD50 for a 129 lb muskrat?
