Answer:
depreciation is $3,333.33 per year
Step-by-step explanation:
Initially : date = 2006, worth = $34,500
Finally : date = 2009, worth = $24,500
if we let x = date and y = worth, we end up with two points (coordinates) on the x-y graph
i.e
Initial = Point 1 (2006, 34500)
Final = Point 2 (2009, 24500)
The rate of change is simply the slope, m of the line joining these two points
given by:
m = (34500 - 24500) / (2006-2009)
= 10000 / -3
= -3,333.33
hence the annual rate of depreciation is $3,333.33 per year
Final answer:
The boat's value depreciated by $10,000 over 3 years, resulting in an annual depreciation rate of $3,333.33.
Explanation:
The student's question involves calculating the annual rate of change of the value of a boat from the year it was bought (2006) to the year 2009. To find the rate of change, we need to determine how much the value of the boat depreciated over the given time period and then divide it by the number of years.
The boat depreciated from $34,500 in 2006 to $24,500 in 2009, which is a decrease of $34,500 - $24,500 = $10,000 over the course of 3 years. To find the annual depreciation rate, we divide the total depreciation amount by the number of years: $10,000 ÷ 3 years = $3,333.33 per year. Therefore, the annual rate of depreciation is $3,333.33 per year, rounded to the nearest hundredth if necessary.

Answer:
3rd choice
Step-by-step explanation:
In division for variables with same base, you do subtract top exponent minus bottom exponent. She did that correctly since -3-(-1)=-3+1=-2 and -2-1=-3.
The problem said m=-2 and n=4 and she replace m with (-2) and n with (4). She did this correctly.
You can multiply base numbers unless the exponents are the same 4 doesn't have the exponent -2 on it so you can't do (4(-2))^(-2)
The error is the 3rd option.
We start with
[tex]\dfrac{4m^{-3}n^{-2}}{m^{-1}n}[/tex]
Simplifying the exponents, we have
[tex]\dfrac{4m^{-3}n^{-2}}{m^{-1}n} = 4m^{-3}n^{-2} (mn^{-1}) = 4m^{-3+1}n^{-2-1}=4m^{-2}n^{-3}[/tex]
So, the exponents are ok.
If we plug the values, we have
[tex]4m^{-2}n^{-3} \mapsto 4(-2)^{-2}(4)^{-3} = 4\cdot \dfrac{1}{(-2)^2}\cdot\dfrac{1}{4^3} = 4\cdot \dfrac{1}{4}\cdot \dfrac{1}{64} = \dfrac{1}{64}[/tex]
So, she didn't apply the exponent -2 correctly.

Andrew is riding his bike. He biked a distance of 14 miles at a rate of 7 miles per hour. Using the distance formula, d = rt, solve for Andrew's time in minutes
d = rt ( d = distance, r = rate (speed) and t = time)
14 = 7t
Divide both sides by 7:
t = 14/7
t = 2 hours
1 hour = 60 minutes.
2 hours x 60 = 120 minutes total.
Based on the distance Andrew went and the rate at which he went, Andrew's time in minutes was 120 minutes.
The distance formula is:
Distance = Rate x Time
Andrew's time is therefore:
14 = 7 x Time
Time = 14 / 7
= 2 hours
In minutes this is:
= 2 x 60 minutes per hour
= 120 minutes
In conclusion, Andrew covered that distance in 120 minutes.

Which ordered pair is the best estimate for the solution of the system of equations?
(7,5, 0.5)
(7, 0.5)
(7,0)
(7,0)
Answer:
The best estimate for the solution of the system of equations is the ordered pair (7, 0.5)
Step-by-step explanation:
The way to solve this problem is to take a deep look into the picture, where we can see that the interception between the lines occurs right in x=7. thus, eliminating the first choice.
Next, we can see that the interception is somewhere far from the 'x' axis, hence 'y' variable can not be zero in this point.
Thus, we have our possible solution, without knowing anything else, the ordered pair (7, 0.5).
Remember, a system of equation has a solution when an interception occurs between its equations

Which of the following is equal to the square root of the cube root of 5 ? (1 point)
5 to the power of 1 over 3
5 to the power of 1 over 6
5 to the power of 2 over 3
5 to the power of 3 over 2
Answer: Second Option
5 to the power of 1 over 6
Step-by-step explanation:
The square root of the cubic root of 5 is written as follows
[tex]\sqrt[2]{\sqrt[3]{5}}[/tex]
Now use the following property of the roots
[tex]\sqrt[m]{\sqrt[n]{x}}=\sqrt[m*n]{x}[/tex]
In this case [tex]m = 2[/tex] and [tex]n=3[/tex] and [tex]x=5[/tex]
So we have that
[tex]\sqrt[2]{\sqrt[3]{5}}=\sqrt[2*3]{5}[/tex]
[tex]\sqrt[2*3]{5}=\sqrt[6]{5}[/tex]
Now use the following property
[tex]\sqrt[n]{x^h}=x^{\frac{h}{n}[/tex]
So we have that:
[tex]\sqrt[6]{5}=5^{\frac{1}{6}}[/tex]
The answer is the second option

Step-by-step explanation:
Solve 4^x- 3 = 18. Round to the nearest thousandth.
4^(x- 3) = 18
ln[4^(x- 3)] = ln(18)
ln4(x - 3) = ln(18)
ln4x - ln4(3) = ln18
ln4x = ln18 + 3ln4
x = [ln18 + 3ln4]/ln4
x = 5.0849625007
x is approximately 5.085.
To solve the equation 4^x - 3 = 18, isolate the exponential term, take the logarithm of both sides, apply the power rule, and then divide to solve for x. The solution to the nearest thousandth is x ≈ 2.416.
Explanation:To solve the equation 4^x - 3 = 18, first add 3 to both sides of the equation to isolate the exponential term:
4^x = 18 + 3
4^x = 21
Now, take the logarithm of both sides. You can use any logarithm base, but it's most common to use either the natural logarithm (ln) or the common logarithm (log base 10). For this example, we'll use the common logarithm.
log(4^x) = log(21)
Using the power rule for logarithms, which states that log(a^b) = b * log(a), you can write:
x * log(4) = log(21)
Now, divide both sides by log(4) to solve for x:
x = log(21) / log(4)
Use a calculator to find the value of x. Be sure to round your answer to the nearest thousandth, as the problem instructs. The answer comes out to:
x ≈ 2.416
This value of x solves the original equation when rounded to the nearest thousandth.
Find f(–2) for the function f(x) = 3x2 – 2x + 7. −13 −1 1 23
Answer:
f(-2) = 23Step-by-step explanation:
[tex]f(x)=3x^2-2x+7\\\\f(-2)\to\text{put x = -2 to the equation of a function:}\\\\f(-2)=3(-2)^2-2(-2)+7=3(4)+4+7=12+4+7=23[/tex]
Answer:
The correct option is 4. The value of f(-2) is 23.
Step-by-step explanation:
The given function is
[tex]f(x)=3x^2-2x+7[/tex]
We have to find the value of f(-2). It means we need to find the value of function f(x) at x=-2.
Substitute x=-2 in the given function to find the value of f(-2).
[tex]f(-2)=3(-2)^2-2(-2)+7[/tex]
On simplification we get
[tex]f(-2)=3(4)-(-4)+7[/tex]
[tex]f(-2)=12+4+7[/tex]
[tex]f(-2)=23[/tex]
The value of f(-2) is 23. Therefore the correct option is 4.

It looks like this question can be grouped using to sets of brackets.
(4r^3 + 10r^2) : Pull out the common factor. 2r^2* (2r + 5)
The second set of brackets is a little bit tricker. Minus signs are not to be ignored.
(-10r - 25) : -5(2r + 5)
Now put both together,
2r^2(2r + 5) - 5(2r + 5)
Notice that there is a common factor on either side of that isolated minus sign. The common factor is 2r + 5. Use the distributive property to pull it out.
(2r + 5)(2r^2 - 5)
It looks like C will be the answer.

Yuri buys a ton of straw every year. The first time he bought straw, in Year 0, it cost $150.00. He
notices the price is getting less expensive, at a rate of 1.5% per year.
Yuri sketches a graph of the situation.
Which statement is true?
Helpppp me
Answer: the graph decreases from left to right
Step-by-step explanation:
because the price over time is getting cheaper the graph will decrease from 0 onward
(pls mark me the brainliest)
Answer:
The graph decreases from left to right.
Step-by-step explanation:
Given,
The original cost of the straw, P = $ 150.00,
The rate of decreasing per year, r = 1.5% = 0.015
Thus, the price after x years,
[tex]C(x)=P(1-r)^x[/tex]
[tex]\implies C(x) = 150(1-0.015)^x=150(0.985)^x[/tex]
Which is an exponential function,
∵ An exponential function [tex]f(x) = ab^x[/tex] has,
Decay : if 0 < b < 1, ( decreasing from left to right )
Growth : if b > 1, ( increasing from left to right )
Since, 0.985 < 1
Thus, the graph is decreasing from left to right,
if x = 2,
C(2) = [tex]150(0.985)^2[/tex] = 145.53375 ≠ 147.75,
I.e. (2, 147.75) does not lie on the graph,
If x = 3,
C(3) = [tex]150(0.985)^3[/tex] = 143.35 ≠ 141.20
i.e. (3, 141.20) does not lie on the graph.

Two poles, AB and ED, are fixed to the ground with the help of ropes AC and EC, as shown:
Two right triangles ABC and EDC have a common vertex C. Angle ABC and EDC are right angles. AB is labeled 13 feet, AC is labeled 15 feet, EC is labeled 10 feet, and ED is labeled 4 feet.

[tex]\bf \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies \sqrt{c^2-b^2}=a \qquad \begin{cases} c=hypotenuse\\ a=adjacent\\ b=opposite\\ \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \sqrt{15^2-13^2}=w\implies \sqrt{225-169}=w\implies \sqrt{56}=w\implies 7.48\approx w \\\\\\ \sqrt{10^2-4^2}=z\implies \sqrt{100-16}=z\implies \sqrt{84}=z\implies 9.17\approx z \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill \stackrel{w+z}{16.65}~\hfill[/tex]
Applying the Pythagorean Theorem, the approximate distance in feet, between the two poles is: b. 16.65 feet
Recall:
For a right triangle where c is the hypotenuse and a and b are the other legs of the right triangle, the Pythagorean Theorem states that: c² = a² + b².
The distance between the two poles = BC + DC
Given:
AB = 13 feetAC = 15 feet EC = 10 feetED = 4 feet.Apply the Pythagorean Theorem to find BC and DC respectively.
Length of BC:
BC = √(AC² - AB²)
SubstituteBC = √(15² - 13²)
BC = 7.48 feet
Length of DC:
DC = √(EC² - ED²)
SubstituteDC = √(10² - 4²)
DC = 9.17 feet
The distance between the two poles = 7.48 + 9.17 = 16.65 feet

what are the domain and range of the function f(x)= 2x+1
Answer:
Domain: All the real numbers
Range: All the real numbers
Step-by-step explanation:
The domain of a function is the complete set of possible values of the independent variable 'x'. That is to say, all the values that 'x' can take:
In this case, f(x)= 2x+1, the independent variable has no restrictions. Meaning that 'x' can take all the Real Values. In set notation: x∈ℝ.
The range of a function is the complete set of all possible resulting values of the dependent variable 'y'. In this case, given that the independent variable has no restrictions, the dependent variable 'y' can take any value. So, the range is: y ∈ ( −∞, ∞ ) - All the real numbers.

y=-x-1
y=-x+5
y=x-1
y=x+5
Answer: [tex]y=-\frac{5}{2}x-1[/tex]
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
[tex]y=mx+b[/tex]
Where "m" is the slope of the line and "b" is the y-intercept.
Write the equation of the given line in Slope-Intercept form by solving for "y":
[tex]5x + 2y = 12\\\\2y=-5x+12\\\\y=-\frac{5}{2}x+6[/tex]
You can observe that the slope of this line is:
[tex]m=-\frac{5}{2}[/tex]
Since the slopes of parallel lines are equal, then the slope of the other line is:
[tex]m=-\frac{5}{2}[/tex]
Now, substitute the slope and the point (-2, 4) into [tex]y=mx+b[/tex] and solve for "b":
[tex]4=-\frac{5}{2}(-2)+b\\\\4=\frac{10}{2}+b\\\\4-5=b\\\\b=-1[/tex]
Then the equation of the line parallel to the given line is:
[tex]y=-\frac{5}{2}x-1[/tex]
ine segment AB has endpoints A(–4, –10) and B(–11, –7). To find the x-coordinate of the point that divides the directed line segment in a 3:4 ratio, the formula x = (x2 – x1) + x1 was used to find that x = (–11 – (–4)) + (–4).
Therefore, the x-coordinate of the point that divides AB into a 3:4 ratio is
Answer:
-7
Step-by-step explanation:
The coordinates of the point wich divide the segment AB, where [tex]A(x_A,y_A),\ B(x_B,y_B)[/tex] in ratio [tex]m:n[/tex] can be calculated using formula
[tex]C\left(\dfrac{nx_A+mx_B}{m+n},\dfrac{ny_A+my_B}{m+n}\right)[/tex]
In your case,
[tex]A(-4,-10)\\ \\B(-11,-7)\\ \\m:n=3:4\Rightarrow m=3,\ n=4[/tex]
Hence,
[tex]C\left(\dfrac{4\cdot (-4)+3\cdot (-11)}{3+4},\dfrac{4\cdot (-10)+3\cdot (-7)}{3+4}\right)\\ \\C\left(-\dfrac{49}{7},-\dfrac{61}{7}\right)\\ \\C\left(-7,-\dfrac{61}{7}\right)[/tex]
Therefore, x-coordinate of the point that divides AB into a 3:4 ratio is -7.

Graph the system of equations. Then determine whether the system has no solution, one solution, or infinitely many solutions. If the system has one solution, name it.
y=-5x+1
y=-2x-2
Answer:
Second option: One solution. Independent.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
[tex]y=mx+b[/tex]
Where "m" is the slope and "b" is the y-intercept.
Since the equations of the system have this form, we know that they are lines.
We can identify that the y-intercept of the first equation [tex]y=-5x+1[/tex] is:
[tex]b=1[/tex]
Now we need to find the x-intercept. Substitute [tex]y=0[/tex] and solve for "x":
[tex]0=-5x+1\\\\5x=1\\\\x=\frac{1}{5}=0.2[/tex]
Then, we can graph the first line which passess through the points (0,1) and (0.2,0). Observe the graph attached.
The y-intercept of the second equation [tex]y=-2x-2[/tex] is:
[tex]b=-2[/tex]
Now we need to find the x-intercept. Substitute [tex]y=0[/tex] and solve for "x":
[tex]0=-2x-2\\\\2x=-2\\\\x=\frac{-2}{2}=-1[/tex]
Then, we can graph the second line, which passess through the points (0,-2) and (-1,0).
You can observe in the graph that the lines intersect at the point (1,-4). Therefore, that point is the solution of the system of equations.
Since the lines intersect, then there is one solution that is true for both equations. It is independent

How do I define slope?
What is slope?
dlqndpQAI:?s
Step-by-step explanation:
Konichiwa~! My name is Zalgo and I am here to help you out on this great day. Hmm, how do you define slope... Well, the slope or "gradient" of a line is a number that describes both the steepness and direction of the line itself. Now, slope is "a surface of which one end or side is at a higher level than another; a rising or falling surface".
I hope that this helps you! :P

which expression is equivalent to sqrt(2x^5/18)? Assume x greater than or equal to 0
For this case we must indicate an expression equivalent to:
[tex]\sqrt {\frac {2x ^ 5} {18}}[/tex]
We rewrite 18 as 2 * 9:
[tex]\sqrt {\frac {2x ^ 5} {2 * 9}} =[/tex]
We simplify common factors:
[tex]\sqrt {\frac {x ^ 5} {9}} =[/tex]
We rewrite:
[tex]x ^ 5 = x ^ 4 * x = (x ^ 2) ^ 2 * x\\9 = 3 ^ 2[/tex]
So, we have:
[tex]\sqrt {\frac {(x ^ 2) ^ 2 * x} {3 ^ 2}} =\\\sqrt {(\frac {x ^ 2} {3}) ^ 2 * x} =[/tex]
We get the terms of the radical "
[tex]\frac {x ^ 2} {3} \sqrt {x}[/tex]
Answer:
[tex]\frac {x ^ 2} {3} \sqrt {x}[/tex]
