Which functions represent a horizontal translation to the left of the parent function f(x) = ln x?
Check all that apply.
g(x) = 3 ln(x − 1) + 6
h(x) = 3 ln(x + 3) + 1
r(x) = −3 ln(x + 1) + 3
s(x) = −3 ln(x) − 3
p(x) = ln(x + 2) − 2
A horizontal shift happens when you add or subtract a value from the input value of x.
To shift left the number would be added to the x.
The answers are:
h(x) = 3 ln(x + 3) + 1
r(x) = −3 ln(x + 1) + 3
p(x) = ln(x + 2) − 2
Answer:
h(x) = 3 ln(x + 3) + 1
r(x) = −3 ln(x + 1) + 3
p(x) = ln(x + 2) − 2
Step-by-step explanation:
The parent function given to us is: [tex]f(x)=\ln x[/tex].
A horizontal translation to the left k units is of the form [tex]y=\ln (x+k)[/tex].
This implies that;
h(x) = 3 ln(x + 3) + 1, is a horizontal translation to the left by 3 units.
r(x) = −3 ln(x + 1) + 3, is a horizontal translation to the left by 1 unit.
p(x) = ln(x + 2) − 2, is a horizontal translation to the left by 2 unit.

Step-by-step explanation:
Write a proportion and show work
for this case we must write a proportion that shows the earnings obtained from Mrs. Miller for the sale of the house.
By making a rule of three we have:
179000 ------------> 100%
x -----------------------> 6%
Where "x" represents the gains obtained.
So:
[tex]x = \frac {6 * 179000} {100}[/tex]
Writing the proportion:
[tex]\frac {x} {179000} = \frac {6} {100}[/tex]
The earns were:
[tex]x = 10740[/tex]
ANswer:
[tex]\frac {x} {179000} = \frac {6} {100}\\x = 10740[/tex]
Answer:
$10,740
Step-by-step explanation:
You know that Mrs. Miller sells a house for $179,000. Then the cost of the house will be the 100%.
Knowing that she earns 6% of comission, you can set up the following proportion (Let be "x" the amount of money she earns), then:
[tex]\frac{\$179,000}{100}=\frac{x}{6}[/tex]
Now you need to solve for "x". Therefore, you get:
[tex](6)(\frac{\$179,000}{100})=x[/tex]
[tex]x=\$10,740[/tex]

Joe’s department store sells pens for 60 cents each and pencils for 40 cents each. Diane purchased a total of 17 items (pens and pencils) for $8.20. How many pens did Diane purchase?
Answer:
Diane purchased 7 pens
Step-by-step explanation:
Let
x----> the number of pens
y----> the number of pencils
we know that
x+y=17
y=17-x -----> equation A
0.60x+0.40y=8.20 -----> equation B
Solve the system of equations by substitution
Substitute equation A in equation B and solve for x
0.60x+0.40(17-x)=8.20
0.60x+6.8-0.40x=8.20
0.20x=8.20 -6.8
x=1.4/0.2=7 pens
Answer: The number of pen purchased by Diane is 7.
Step-by-step explanation: Given that Joe’s department store sells pens for 60 cents each and pencils for 40 cents each.
Diane purchased a total of 17 items for $8.20.
We are to find the number of pen that Diane purchased.
We know that
1 cent = $ 0.01.
Let x and y represents the number of pen and pencils that Diane purchased.
Then, according to the given information, we have
[tex]60\times0.01x+40\times 0.01y=8.20\\\\\Rightarrow 0.6x+0.4y=8.20\\\\\Rightarrow 6x+4y=82~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
and
[tex]x+y=17\\\\\Rightarrow y=17-x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]
Substituting the value of y from equation (ii) in equation (i), we get
[tex]6x+4y=82\\\\\Rightarrow 6x+4(17-x)=82\\\\\Rightarrow 6x+68-4x=82\\\\\Rightarrow 2x=82-68\\\\\Rightarrow 2x=14\\\\\Rightarrow x=\dfrac{14}{2}\\\\\Rightarrow x=7.[/tex]
Thus, the number of pen purchased by Diane is 7.

Step-by-step explanation:
find the area of the figure 11.2 in 6.7 in
Without more information on the shape, it's not possible to provide the area of the figure from just the provided dimensions. Assuming it's a rectangle and using significant figures, the example calculation yields an area of 4.1 cm² when multiplying 0.6238 cm by 6.6 cm and rounding to two significant figures.
Explanation:To find the area of a figure with given dimensions, one would typically multiply the length by the width. However, the question provided seems to be missing specific details about the shape of the figure. Given the figure's dimensions, if we assume it is a rectangle, the calculation would be straightforward: multiply the length by the width. Unfortunately, without additional information about the exact shape or context provided by equations or a figure reference, it is not possible to provide an accurate answer. It's essential to verify the shape and relevant equations before proceeding with the area calculation.
However, based on the examples given, to calculate the area with significant figures, one must consider the number of significant figures in the given dimensions. For example, if we multiply 0.6238 cm by 6.6 cm, the result is 4.11708 cm², which we round to 4.1 cm² (to two significant figures) because we are multiplying a number with four significant figures by a number with two significant figures.
ASAP!! Graph the function. f(x)=−15x+4 Use the Line tool and select two points to graph.
To graph the function f(x) = -15x + 4, plot the points (0,4) and (1,-11) on the graph. The slope of the line is -15 and the y-intercept is 4.
Explanation:To graph the equation f(x) = -15x + 4, you need to plot two points on a graph then draw a line through those points. First, plug in value x = 0 into the equation, you get f(0) = -15*(0) + 4 = 4. So, one point is (0,4). Second, let's plug another x value, for example, x = 1, into the function. Hence, f(1) = -15*(1) + 4 = -11, giving you the second point (1,-11).
Also remember that this is a linear function and you'll see that it forms a straight line when graphed. The slope of the line is -15, which means the line will fall to the right. The y-intercept of the line is 4, which is the point where the line crosses the y-axis.

The graph of f(x) = -15x + 4 is a line with a slope of -15 and a y-intercept of 4. Connecting points (0, 4) and (1, -11) depicts the downward-sloping trend.
To graph the linear function f(x) = -15x + 4, we can use the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope (m) is -15, and the y-intercept (b) is 4.
To create the graph, we choose two points and connect them with a line. Let's select x = 0 and x = 1 to find the corresponding y-values.
For x = 0: y = -15(0) + 4 = 4. So, the point (0, 4) is on the graph.
For x = 1: y = -15(1) + 4 = -11. The point (1, -11) is on the graph.
Now, we can use these two points to draw the line on the coordinate plane. The line will have a negative slope, indicating a downward trend, and it intersects the y-axis at 4.
In summary, the graph of f(x) = -15x + 4 is a downward-sloping line that passes through the point (0, 4) and (1, -11).

The angels are ADJACENT ANGELS
Answer:
21
(Side Note: I solved this for anyone who needs the answer.)
Definitions:
Adjacent: Congruent meaning same measure.
Vertical: Two angles that have a common side.
Explanation:
This equation is adjacent.
If we look at this problem and look to the bottom and see that tiny square, that means it is a right angle, right angles equal to 90 degrees.
Step-By-Step:
To solve for x, we need to put 25 degrees and x into a formula.
x + 35 = 90
Next and the last step is to subtract 90 and 35:
90 - 35 = 21
Our final answer is 21.

(3 + 5) * 2Y = (5 * 8) - (2 * 4)
Answer:
Y = 2
Step-by-step explanation:
Solve for Y:
(3 + 5)×2 Y = 5×8 - 2×4
3 + 5 = 8:
8×2 Y = 5×8 - 2×4
5×8 = 40:
8×2 Y = 40 - 2×4
-2×4 = -8:
8×2 Y = -8 + 40
8×2 = 16:
16 Y = 40 - 8
40 - 8 = 32:
16 Y = 32
Divide both sides of 16 Y = 32 by 16:
(16 Y)/16 = 32/16
16/16 = 1:
Y = 32/16
The gcd of 32 and 16 is 16, so 32/16 = (16×2)/(16×1) = 16/16×2 = 2:

The cost to rent an instrument is $65 for the first month. It costs $30 for each additional month, x, that the instrument is rented. Which expression represents the total cost of renting the instrument?
A. 30 + 65x | B. x + 35 | C. 65 + 30x | D. x + 95
Final answer:
The total cost of renting the instrument is represented by the expression 65 + 30x, which accounts for the initial rental fee and the additional cost per subsequent month.
Explanation:
The expression that represents the total cost of renting the instrument is C = 65 + 30x, which is option C. To understand this, consider that there is a flat rental fee of $65 for the first month and an additional cost of $30 for each subsequent month an instrument is rented. The variable x represents the number of additional months the instrument is rented. Therefore, the total cost is given by the initial cost plus the cost for additional months, which in algebraic terms is 65 + 30x.
Which of the following describes the roots of the polynomial function K x) - (x+ 2)(x-4)(x+1)3?
Answer:
It's the first option.
Step-by-step explanation:
(x + 2)^2 gives a duplicate (multiplicity 2) root. (because (x + 2)^2 = 0 so x = -2 multplicity 2)
(x - 4) gives one root of 4.
(x + 1)^3 gives x = -1 with multiplicity 3.
Answer:
-2 with multiplicity 2, 4 with multiplicity 1, and -1 with multiplicity 3.
Step-by-step explanation:
The given polynomial function is: [tex]f(x)=(x+2)^2(x-4)(x+1)^3[/tex].
To find the roots of this polynomial, we equate each factor to zero.
This implies that;
i. [tex](x+2)^2=0[/tex], [tex]\implies x=-2[/tex], the multiplicity of this root is 2, because the factor repeats twice
ii. [tex]x-4=0[/tex], [tex]\implies x=4[/tex], the multiplicity of this root is 1, because the factor repeats once.
ii. [tex](x+1)^3=0[/tex], [tex]\implies x=-1[/tex], the multiplicity of this root is 3, because the factor repeats three times.

Step-by-step explanation:
Using the trigonometric identities
• 1 + tan²x = sec²x
• cot x = [tex]\frac{1}{tanx}[/tex]
Given
secΘ = [tex]\frac{4}{3}[/tex], then
tan²Θ = sec²Θ - 1 = ([tex]\frac{4}{3}[/tex] )² - 1 = [tex]\frac{16}{9}[/tex] - 1 = [tex]\frac{7}{9}[/tex], hence
tanΘ = ± [tex]\sqrt{\frac{7}{9} }[/tex] = ± [tex]\frac{\sqrt{7} }{3}[/tex]
Since 270° < Θ < 360° ← fourth quadrant where tanΘ < 0
Hence tanΘ = - [tex]\frac{\sqrt{7} }{3}[/tex]
and
cotΘ = [tex]\frac{1}{-\frac{\sqrt{7} }{3} }[/tex] = - [tex]\frac{3}{\sqrt{7} }[/tex] = - [tex]\frac{3\sqrt{7} }{7}[/tex]
A projectile is thrown upward so that its distance above the ground after t seconds is given by the function h(t) = -16t2 + 704t. After how many seconds does the projectile take to reach its maximum height? Show your work for full credit.
Final answer:
The projectile reaches its maximum height after 22 seconds, which is determined by the vertex formula t = -b/(2a) applied to the given quadratic function representing the height over time.
Explanation:
To determine after how many seconds the projectile reaches its maximum height, we need to analyze the function h(t) = -16t2 + 704t. This is a quadratic function, and the maximum height will be reached at the vertex of the parabola represented by this function.
The vertex of a parabola given by ax2 + bx + c can be found using the formula t = -b/(2a), where a, b, and c are coefficients from the quadratic equation. In this case, a = -16 and b = 704.
Using the formula to find the time t when the projectile reaches its maximum height, we calculate: t = -704/(2 × -16) = 704/32 = 22. Therefore, the projectile reaches its maximum height after 22 seconds.
Please help me with this!!
Step-by-step explanation:
To find the y-coordinate points we need to evaluate the function for all the [tex]x[/tex] values in the table. In other words, we need to replace [tex]x[/tex] with each value in our given function and simplify.
- For x = 0
[tex]f(x)=(x-2)^2-5[/tex]
[tex]f(0)=(0-2)^2-5[/tex]
[tex]f(0)=(-2)^2-5[/tex]
[tex]f(0)=4-5[/tex]
[tex]f(x)=-1[/tex]
Since [tex]x=0[/tex] and [tex]y=-1[/tex], our first point is (0, -1)
- For x = 1
[tex]f(x)=(x-2)^2-5[/tex]
[tex]f(1)=(1-2)^2-5[/tex]
[tex]f(1)=(-1)^2-5[/tex]
[tex]f(1)=1-5[/tex]
[tex]f(x)=-4[/tex]
Our second point is (1, -4)
- For x = 2
[tex]f(x)=(x-2)^2-5[/tex]
[tex]f(2)=(2-2)^2-5[/tex]
[tex]f(2)=(0)^2-5[/tex]
[tex]f(x)=-5[/tex]
Our third point is (2, -5)
- For x = 3
[tex]f(x)=(x-2)^2-5[/tex]
[tex]f(3)=(3-2)^2-5[/tex]
[tex]f(3)=(1)^2-5[/tex]
[tex]f(3)=1-5[/tex]
[tex]f(x)=-4[/tex]
Our fourth point is (3, -4)
- For x = 4
[tex]f(x)=(x-2)^2-5[/tex]
[tex]f(4)=(4-2)^2-5[/tex]
[tex]f(4)=(2)^2-5[/tex]
[tex]f(4)=4-5[/tex]
[tex]f(x)=-1[/tex]
Our fifth point is (4, -1)
Now we just need to plot each point in our coordinate plane and join them with the parabola as you can see in the attached picture.
Complete the square to solve the equation below.
X^2 +x=11/4
Answer:
The solutions of the equation are √3 - 1/2 and -√3 - 1/2
Step-by-step explanation:
* Lets revise how to make the completing square
- The form of the completing square is (x - h)² + k, where h , k
are constant
- The general form of the quadratic is x² + bx + c, where b , c
are constant
- To change the general form to the completing square form equate
them and find the constant h , k
* Now lets solve the problem
∵ x² + x = 11/4 ⇒ subtract 11/4 from both sides
∴ x² + x - 11/4 = 0
- Put the equation equal the form of the completing square
∵ x² + x - 11/4 = (x - h)² + k ⇒ solve the bracket power 2
∴ x² + x - 11/4 = x² - 2hx + h² + k
- Equate the like terms
∵ x = -2hx ⇒ divide both sides by x
∴ 1 = -2h ⇒ divide both sides by -2
∴ -1/2 = h
∴ the value of h = -1/2
∵ -11/4 = h² + k
- Substitute the value of h
∴ -11/4 = (-1/2)² + k
∴ -11/4 = 1/4 + k ⇒ subtract 1/4 from both sides
∴ -12/4 = k
∴ k = -3
∴ The value of k is -3
- Substitute the value of h and k in the completing square form
∴ (x - -1/2)² + (-3) = 0
∴ (x + 1/2)² - 3 = 0 ⇒ add 3 to both sides
∴ (x + 1/2)² = 3 ⇒ take square root for both sides
∴ x + 1/2 = √3 OR x + 1/2 = -√3
∵ x + 1/2 = √3 ⇒ subtract 1/2 from both sides
∴ x = √3 - 1/2
OR
∵ x + 1/2 = -√3 ⇒ subtract 1/2 from both sides
∴ x = -√3 - 1/2
* The solutions of the equation are √3 - 1/2 and -√3 - 1/2

Answer:
1500(1.0115)^(2t)
Step-by-step explanation:
The formula for the balance in an account earning compound interest is ...
A = P(1 +r/n)^(nt)
where P is the principal invested, r is the annual rate, n is the number of times per year interest is compounded, and t is the number of years.

Using the given values in the formula, we have ...
A = 1500(1 +0.023/2)^(2t)
Simplifying a bit, this is ...
A = 1500(1.0115)^(2t) . . . . . CD value after t years
Replacing only the minimum value in a data to a smaller number will also change the mean
A.always
B. Sometimes
C.never true
Answer:
Always.
Step-by-step explanation:
I can think of no example that makes always false.
Replacing the minimum value in a dataset with a smaller number can sometimes change the mean. Hence, the correct answer is B.
Sometimes, replacing only the minimum value in a dataset with a smaller number may change the mean.
For example, if the dataset is {1, 3, 4, 5} and you replace the minimum value 1 with 0, the mean changes from 3.25 to 3.
