In 1972 a Honda Civic went for $2000, today a Honda civic sells for around $25000. The rate of inflation is %
Answer:
5.1%
Step-by-step explanation:
You want the rate of inflation if the price of a Honda Civic increase from $2000 in 1972 to $25000 in 2023.
InflationThe rate of inflation can be computed from ...
r = (p1/p0)^(1/t) -1
r = (25000/2000)^(1/51) -1 ≈ 0.05077 ≈ 5.1%
The rate of inflation is about 5.1%.

Complete the square. Fill in the number that makes the polynomial a perfect-square quadratic. x2 + 12x + 36 12 6 24
Answer:
x2 + 6x + 9
Step-by-step explanation:
There is one "special" factoring type that can actually be done using the usual methods for factoring, but, for whatever reason, many texts and instructors make a big deal of treating this case separately. "Perfect square trinomials" are quadratics which are the results of squaring binomials. (Remember that "trinomial" means "three-term polynomial".) For instance:
(x + 3)2
= (x + 3)(x + 3)
= x2 + 6x + 9
...so x2 + 6x + 9 is a perfect square trinomial.
The trick to seeing this pattern is really quite simple: If the first and third terms are squares, figure out what they're squares of. Multiply those things, multiply that product by 2, and then compare your result with the original quadratic's middle term. If you've got a match (ignoring the sign), then you've got a perfect-square trinomial. And the original binomial that they'd squared was the sum (or difference) of the square roots of the first and third terms, together with the sign that was on the middle term of the trinomial.
Find two integers whose product is 20 and whose sum is 9. (enter your answers as a comma-separated list.)
To find two integers whose product is 20 and whose sum is 9, you can use the following steps:
1. Let the two integers be x and y.
2. Write down the given conditions as equations:
a) x * y = 20 (product condition)
b) x + y = 9 (sum condition)
3. Solve the equations simultaneously.
a) From the sum condition, y = 9 - x
b) Substitute this expression for y into the product condition: x * (9 - x) = 20
4. Expand and rearrange the equation:
x^2 - 9x + 20 = 0
5. Factor the quadratic equation:
(x - 4)(x - 5) = 0
6. Find the integer solutions for x:
x = 4 or x = 5
7. Find the corresponding y values:
a) If x = 4, y = 9 - 4 = 5
b) If x = 5, y = 9 - 5 = 4
Therefore the two integers are 4 and 5.

dilating a triangle changes the shape of the triangle but does not change its size
Answer:
false it does not change the shape but it does change the size
Step-by-step explanation:
False, because Dilating a triangle changes the size of the triangle but does not change its shape.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Since,
Dilation is a type of transformation which stretches and reduces the size of the original figure.
A dilation has a center of dilation and a dilation scale factor. If the scale factor is less than one then the original size will shrink, and if the scale factor is greater than one then the figure will increase in size.
Dilation transformation does not alter the shape of a figure but alters the size by making it bigger or smaller.
Thus, We can say that;
Dilating a triangle changes the size of the triangle but does not change its shape.

The gas mileage m (x) (in mpg) for a certain vehicle can be approximated by m (x)=-0.025x²+2.618x-35.021, where x is the speed of the vehicle in mph. Part: 0/2 Part 1 of 2 (a) Determine the speed at which the car gets its maximum mileage. Round your answer to the nearest mph. mph. The gas mileage is at a maximum when the car travels at X
Rounding to the nearest whole number, the speed at which the car gets its maximum mileage is approximately 52 mph.
To determine the speed at which the car gets its maximum mileage, we need to find the x-value at which the function reaches its maximum point. In this case, the function represents gas mileage (m) as a function of speed (x).
The given function for gas mileage is:
m(x) = -0.025x² + 2.618x - 35.021
To find the maximum point, we can use calculus. The maximum point occurs at the vertex of the quadratic function, and the x-coordinate of the vertex can be found using the formula:
x = -b / (2a)
In our case, the quadratic function is in the form:
f(x) = ax² + bx + c
Comparing the function m(x) = -0.025x² + 2.618x - 35.021 with the general form, we can see that:
a = -0.025
b = 2.618
Using the formula x = -b / (2a), we can calculate the speed at which the car gets its maximum mileage:
x = -(2.618) / (2 * (-0.025))
x = -2.618 / (-0.05)
x ≈ 52.36
Rounding to the nearest whole number, the speed at which the car gets its maximum mileage is approximately 52 mph.

details scalccc4 8.1.049. my notes practice another determine whether the sequence is increasing, decreasing, or not monotonic. an = 1/3n 4
To determine whether the sequence \(\(a_n = \frac{1}{3n^4}\)\) is increasing, decreasing, or not monotonic, we can analyze the behavior of the terms as \(\(n\)\)increases.
Let's calculate the values of \(\(a_n\)\) for a few values of \(\(n\)\) to observe any patterns:
\(\(a_1 = \frac{1}{3(1)^4} = \frac{1}{3}\)\)
\(\(a_2 = \frac{1}{3(2)^4} = \frac{1}{48}\)\)
\(\(a_3 = \frac{1}{3(3)^4} = \frac{1}{243}\)\)
\(\(a_4 = \frac{1}{3(4)^4} = \frac{1}{768}\)\)
We can see that as \(\(n\)\) increases, the values of \(\(a_n\)\) are decreasing. This indicates that the sequence is decreasing.
To formally prove this, we can compare the terms \(\(a_n\)\) and \(\(a_{n+1}\)\) for any \(\(n\)\) :
\(\(a_n = \frac{1}{3n^4}\)\)
\(\(a_{n+1}\) = \(\frac{1}{3(n+1)^4}\)\)
To determine if \(\(a_n\)\) is less than \(\(a_{n+1}\)\) , we can simplify and compare the fractions:
\(\(\frac{1}{3n^4} < \frac{1}{3(n+1)^4}\)\)
Cross-multiplying and simplifying:
\(\(3(n+1)^4 < 3n^4\)\)
Expanding the binomial and further simplifying:
\(\(n^4 + 4n^3 + 6n^2 + 4n + 1 < n^4\)\)
Since the left side of the inequality is positive and the right side is \(\(n^4\)\) (which is positive for all \(\(n\))\) , we can see that the inequality is not true for any \(\(n\).\) Therefore, \(\(a_n\)\) is always less than \(\(a_{n+1}\)\) , indicating that the sequence is decreasing.
In conclusion, the sequence \(\(a_n = \frac{1}{3n^4}\)\) is a decreasing sequence.

What is the magnitude of vector R, And Direction of R ?
The sum of the given two vectors A and B is found to be R = 3i + 3j. The magnitude of vector R is found to be 3√2 and its direction is 45°.
The sum of the two vectors A and B is given by: R = A + B
Here, vector A = i + 4j And, vector B = 2i - j
Now, to find R, we will add the respective components of the two vectors, i.e,
R = (i + 4j) + (2i - j)
= 3i + 3j
The magnitude of vector R is given by the formula:
|R| = \(\sqrt{(R_x^2 + R_y^2)}\)
Substituting the values,
|R| = √(3² + 3²) = √18 = 3√2
The direction of vector R is given by the formula:
θ = tan⁻¹(\(R_y/R_x\))
θ = tan⁻¹(3/3)
θ = 45°
Therefore, the magnitude of vector R is 3√2 and its direction is 45°.

(9,−7) after a dilation by a scale factor of 4 centered at the origin?
The image of the coordinates after a dilation of (9, −7) by a scale factor of 4 centered at the origin include the following: (36, -28).
What is dilation?In Geometry, dilation can be defined as a type of transformation which typically changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.
Next, we would have to dilate the coordinates of the preimage (9, -7) by using a scale factor of 4 centered at the origin as follows:
Coordinate A (9, -7) → Coordinate A' (9 × 4, -7 × 4) = Coordinate A' (36, -28).
In conclusion, the coordinates of the image after a dilation are (36, -28).

a child is selected at random. let the random variable x be the age of the child. find the probability distribution of x. (enter your probabilities as fractions.
We can make some assumptions of a possible probability distribution. However, it's important that this probability distribution is based on a set of assumptions
Let's assume that the ages of children in the population of interest are integers between 1 and 10, and that each age has an equal probability of being selected. In this case, the probability distribution of the age of a child would be:
x P(X=x)
1 1/10
2 1/10
3 1/10
4 1/10
5 1/10
6 1/10
7 1/10
8 1/10
9 1/10
10 1/10
This probability distribution assigns a probability of 1/10 to each age between 1 and 10, indicating that each age is equally likely to be selected. Note that the sum of all probabilities equals 1, as it should be for any probability distribution.
However, it's important to note that this probability distribution is based on a set of assumptions, and in reality, the ages of children may not follow this exact distribution. It's always important to carefully consider the assumptions underlying any probability model and to gather as much relevant data as possible to inform the model.

when the sample size is small, the main assumptions of parametric tests may be violated. State True or False
True. Parametric tests are a category of statistical tests that can only be applied to data that meets certain criteria.
They make use of normal distribution assumptions when analyzing data, which means that a significant proportion of the data must follow a normal distribution for the test to produce valid outcomes
.A sample is a subset of the population that is being examined. The size of the sample has an impact on the accuracy of the study. If the sample size is insufficient, it may not be representative of the entire population. In small sample sizes, the main assumptions of parametric tests may be violated, and the results of the test may be skewed.
A sample is a group of individuals or objects from a population that are chosen for a study. The size of the sample is critical since it has a direct impact on the statistical accuracy of the data. A small sample size can cause the primary assumptions of parametric tests to be broken.
Parametric tests are a type of statistical test that can only be used with specific kinds of data. When parametric tests are used to evaluate data, it is assumed that the data follows a normal distribution. In general, this means that the data should be symmetric around the mean, with the majority of the data values being near the mean and fewer outliers. However, when the sample size is small, the accuracy of these assumptions may be in doubt.
As a result, it's crucial to ensure that you choose the proper statistical test based on the size of your sample and the distribution of your data.
