The number of cows a farmer has on his farm over several years can be modeled by an arithmetic sequence. During the 2nd, 5th, and 7th years, he has 30, 39, and 45 cows, respectively. How many cows did the farmer have in his first year on the farm?
As per the arithmetic sequence, the farmer have 21 cows in his first year on the farm
An arithmetic sequence is a sequence of numbers in which each successive number is obtained by adding a fixed number to the previous number.
To determine the common difference, we can take the difference between any two consecutive terms in the sequence.
The difference between the 2nd and 5th years is 9 cows
=> (39 - 30 = 9).
Now that we know the common difference is 9, we can use it to find the first term of the sequence. To do this, we can take the second term (30 cows) and subtract the common difference from it.
This would give us the first term of the sequence, which is 21 cows.
Therefore, the farmer had 21 cows in his first year on the farm.

Answer:
Quadrant III, sin θ = -12/13
Step-by-step explanation:
To solve this problem we can look at a unit circle (attached below). We can observe the following about the quadrants:
cos θ = 5/13 falls into the first OR fourth quadrant since cos (67) = 5/13 (roughly, obtained with inverse cosine function). However, we also have the restriction that sin θ < 0, therefore the quadrant that cos θ falls into is the fourth quadrant.
To find sin θ we first consider that cosine is adjacent over hypoteneuse. So, a = 5 and h = 13. Using pythagorean theorem we find that o (opposite) is equal to 12. Since sine is opposite over hypoteneuse we have:
sin θ = ±12/13
We use the plus or minuse sign because sin θ maps to both a positive and negative value, even though we used a geometrical approach, we still have to consider this. Of course, we know that sin θ has to be negative (given in the problem) so sin θ is -12/13.
Part 2- Calculate Relative Frequencies
Calculate the relative frequencies for Tables 1 and 2 by dividing the value in each cell by the total for that table.
(For example, to calculate the relative frequency of men in Cambridge who walked to work, divide 8,110 by
20,276. You should get a decimal between 0 and 1 that, after moving the decimal point to the right two places,
represents the proportion of men in Cambridge who walked to work.) Round your numbers to the nearest whole
percentage and place them in Tables 3 and 4.
The relative frequency of men in Cambridge who walked to work is 0.39
How to find the relative frequency?Relative frequency is defined as the ratio of the considered sub group's count to the total count. (so its frequency of the considered sub group relative to the total frequency).
We have to consider that frequency of men in Cambridge who walked to work, 8,110 by 20,276.
In order to find the relative frequencies for Tables 1 and 2 by dividing the value in each cell by the total for that table.

The function that can be graphed is option (d) f(x) = √(x + 1) + 8
Functions are commonly used in mathematics to describe relationships between variables.
To determine which of the four functions could be graphed, we first need to identify the curve's intercepts and asymptotes.
From the graph, we can identify the intercepts as (0,8) and (–3,0). The asymptotes are given by the equations x = 0 and y = 8. We can then use these points to compare the given functions and determine which one could be used to graph the curve.
Of the four functions, only f(x) = √(x + 1) + 8 fits the given description. This function has intercepts at (0,8) and (–3,0) and asymptotes at x = 0 and y = 8. Thus, f(x) = √(x + 1) + 8 is the function that could be graphed

These retain more complicated result sets involving one, zero, horizonless or any number of results, but work also to direct systems in that their results are the points satisfying all equations involved.

10 is five times larger than 2, and the ratio of blue to white marbles in the population is 1:5
What is ratio ?
Ratio can be defined as given value divided by total value.
The ratio of blue marbles to white marbles in the population is:
9 blue marbles : 45 white marbles
which simplifies to:
1 blue marble : 5 white marbles
If a representative sample contains 2 blue marbles, we can use this ratio to find the expected number of white marbles in the sample:
2 blue marbles × 5 white marbles/blue marble = 10 white marbles
Therefore, we would expect the representative sample to contain 10 white marbles.
To explain this result, we can think of the representative sample as a smaller version of the population, where the ratio of blue marbles to white marbles is the same. Since we know that the ratio of blue to white marbles in the population is 1:5, we can use this ratio to estimate the number of white marbles we would expect to see in the sample, given that we have observed 2 blue marbles. In this case, we would expect to see 10 white marbles,
Hence, 10 is five times larger than 2, and the ratio of blue to white marbles in the population is 1:5

In mathematics, what is dilation?
Dilation is the process of changing the size of an object or form by shrinking or extending its dimensions based on certain scale variables. For example, a circle with radius 10 unit is decreased to a circle with radius 5 unit and there are only four basic types of transformations. They are as follows:
RotationTranslationReflectionDilation or ResizingSome characteristics stay constant during dilation are:
The figure's angles are all the same.The midpoints of the figure's sides stay the same as the midpoint of the dilated form.The figure's parallel and perpendicular lines stay the same as the dilated figure's parallel and perpendicular lines.The visuals stay unchanged.Now,
Before reflection
Coordinates of V are (−3, −1).
and reflection of V is across y=-x, which will make values for x and y opposite or change the sign of coordinates.

the value of x will be 8√2 for the given right-angle triangle.
What is the right-angle triangle?A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.
Given, Two right-angle triangles one with the height of "x" and a base angle of 45-degree.
Another with a base of 8 and a base angle of 60-degree.
From the cosine rule of trigonometry:
Cos θ = base/(hypotenuse)
Sin θ = height/(hypotenuse)
For the triangle with a base angle of 45-degree
sin 45 = height/(hypotenuse)
1/√2 = x/(hypotenuse)
hypotenuse = x *√2.....(1)
For the triangle with a base angle of 60-degree
cos 60 = base/(hypotenuse)
1/2 = 8/(hypotenuse)
hypotenuse = 16
substitute this value in equation 1
x = 8√2
therefore, the value of x will be 8√2 for the given right-angle triangle.

Two vectors are linearly dependent if and only if they are collinear.
True/False
The given statement "Two vectors are linearly dependent if and only if they are collinear" is true because one is a scalar multiple of the other.
Two vectors are linearly dependent if and only if one of them is a scalar multiple of the other. This means that if you have two vectors, say v and w, then there exists a scalar c such that v = cw or w = cv.
If v and w are collinear, then they lie on the same line and one is a scalar multiple of the other. Specifically, if v = (a, b) and w = (c, d) are collinear, then there exists a scalar k such that v = kw, which means that a = kc and b = kd.
Conversely, if v and w are linearly dependent, then one is a scalar multiple of the other, which means that they lie on the same line and are collinear.

A decimal number can be defined as a number whose whole number part and fractional part are separated by a decimal point. Writing 2/5 as a decimal number by converting the denominator to powers of 10. We multiply the numerator and denominator by a number so that the denominator is a power of 10.
2/5 = (2 × 2) / (5 × 2) = 4/10
Now move the decimal point to the left as many places as there are zeros in the denominator, which is a power of 10.
