The function that represent the given table is f(x) = 2n+1.
In the given question we have to write the correct function for the table given below.
The given table is
x y
0 3
1 5
2 7
3 9
We can write it as
x y
0 3=1+2
1 5=3+2
2 7=5+2
3 9=7+2
So we can see that in each odd number we are adding 2.
So the function should be
f(x) = (2n−1)+2
f(x) = 2n−1+2
f(x) = 2n+1
Hence, the function that represent the given table is f(x) = 2n+1.

A boat is heading towards a lighthouse, where Yaritza is watching from a vertical distance of 139 feet
Yaritza measures an angle of depression to the boat at point AA to be 21°
Yaritza takes another measurement and finds the angle of depression to the boat (now at point BB) to be 50°
the distance from point AA to point BB = ?
The direction of movements describes a right triangle of
opposite = ?
adjacent = 139 feet
The distance is calculated using tan, TOA let the angle be x
tan x = Opposite / Adjacent
for x = 21 point AA is solved
tan 21 = ? / 139
? = 139 * tan 21
? = 53.357
for x = 50 point BB is solved
? = 139 * tan 50
? = 165.654
the distance from point AA to point BB
= 165.654 - 53.357

Answers
Answer: 3 is less than 7, the absolute value of 3 is less than the absolute value of 7
Step-by-step explanation: Absolute value is how far a number is from 0. the best way to show absolute value is to test how far away the number is from 0 by using a number line. For example, the absolute value of -9 would be 9, or the absolute value of 5 would be 5. Absolute value is the amount of distance between the number and 0.

Use a determinant to find the area of the triangle in R^2 with vertices (-4, -4), (0,-2), and (-2, 4) Hint: A triangle is half a parallelogram.
Answers
Area of the triangle in R² using determinant for the given vertices (-4, -4) , (0,-2) and (-2,4) is equal to 14 square units.
As given in the question,
Vertices of the triangle are given by:
( x₁ , y₁ ) = (-4,-4)
(x₂ , y₂) = (0, -2)
( x₃ , y₃) = (-2, 4)
Area of triangle using determinant is given by
= [tex]\frac{1}{2} \left|\begin{array}{ccc}-4&-4&1\\0&-2&1\\-2&4&1\end{array}\right|[/tex]
= (1/2) [-4(-2 -4) + 4(0+2) +1(0-4)]
=(1/2) ( 24 + 8 - 4)
= (1/2) ( 28)

Find the missing values in the ratio table. Then write the equivalent ratios. Burgers 3 9 hot dogs 5 10 the equivalent ratios are $3:$ , $:10$ , and $:$.
Answers
The required ratio for the burger is 3:6:9 and the ratio for the hot dog is 5:10:15.
Let the missing ratio in Burger be x and the ratio in the Hot dogs be y,
Now,
According to the question,
3 / 5 = x / 10
x = 6
Now,
x / 10 = 9 / y
Substitute the value of x,
6 / 10 = 9 / y
y = 90 / 6
y = 15
Thus, the required ratio for the burger is 3;6:9 and the ratio for the hot dog is 5:10:15.
In mathematics, a ratio suggests how commonly one variety consists of another. for example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to 6 (this is, eight:6, that's equal to the ratio four:3). similarly, the ratio of lemons to oranges is 6: 8 (or 3:4) and the ratio of oranges to the total amount of fruit is 8:14 (or 4:7).
The numbers in a ratio may be quantities of any kind, consisting of counts of human beings or items, or which include measurements of lengths, weights, time, and many others. In maximum contexts, each number is constrained to be advantageous.
A ratio may be specified either by way of giving each constituting number, written as "a to b" or "a: b", or through giving simply the price of their quotient a/b. identical quotients correspond to the same ratios.
Consequently, a ratio may be considered as an ordered pair of numbers, a fraction with the first number inside the numerator and the second one in the denominator, or as the price denoted by using this fraction. Ratios of counts, given via (non-zero) herbal numbers, are rational numbers, and might occasionally be natural numbers. while portions are measured with the same unit, as is often the case, their ratio is a dimensionless number. A quotient of quantities that are measured with distinct devices is referred to as a rate.

The ratio of the size of the event space to the size of the sample space is the probability of an event.
The total number of possible outcomes is the size of the sample space.
The number of outcomes in the event you are interested in is called the event space.
Using the formula,

Function A has a rate of change of 5 & function B has a rate of change of -4.5. so, function A has a greater rate of change.
What is the rate of change?
The rate at which a variable changes over a given time period. It is frequently used when discussing momentum, and it can be expressed as a ratio of a change in one variable to a corresponding change in another. This ratio is represented graphically by the slope of a line.
For the first function, we can use the equation of the slope
[tex]m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
take any two points,
m = (25-15)/5.5-3.5 = 10/2 = 5
The general equation of a straight line is;
y = mx + c
where m is the slope
Therefore, in the case of the second equation, -4.5 is the slope
Hence, function A has a rate of change of 5 & function B has a rate of change of -4.5. so, function A has a greater rate of change.

a process used to manufacture paint yields, on the average, 70 tons of paint each day. yields, however , vary from day to day due to changes in raw materials and plant conditions. suppose, it is established that the daily yields are normally distributed, and that the variability from one day to the other is more or less independent , and the standard deviation is 3 tons. because of increasing demand for this type of paint, certain modifications are suggested , and we are interested in estimating the mean yield of this modified process. how many sample observations do we have to obtain if we want to be 98% confident that our estimate is within 1 ton of the true, but unknown mean?
Answers
Using the Sample size formula , the sample manufactuer of paints observations or sample size is 22 ton .
Sample size: It is defined as the number of participants or total observations in a study of sample.
we have provided that,
standard deviations of sample (σ)= 3 tons
mean of sample ( X) = 70 tons
confidence level = 98% = 0.98
Margin of error (M.E) = 1 ton
Using the sample size formula,
n = z²(σ)(1-σ) /( M.E)²[1+σ (1-σ)z²/(M.E)²X]
where, X---> population size
s.d --> standard deviations
M.E ---> margin of error
Z-value for confidence level
so, z-value corresponding to 98% of confidence level is 2.32 ..
putting all the values in above formula we get, n = (2.32)²(2)3/(1)²(1+ (2.32)²(6)70×1)
=> n= 32.29/(1+(0.46))= 32.29/ 0.46

The comparison of the linear functions to line A are given as follows:
y = 4x ± constant: parallel.y = -x/4 ± constant: perpendicular.y = x/4 ± constant: neither parallel nor perpendicular.When are lines parallel, perpendicular or neither?A linear function is defined as follows:
y = mx + b.
In which the coefficients are listed as follows:
m is the slope.b is the intercept.The slope determines if the lines are parallel, perpendicular, or neither, as follows:
If the slopes for both lines are equal, the lines are parallel.If the multiplication of the slopes of both lines is of -1, they are perpendicular.Otherwise, they are neither.In this problem, the function is:
y = 4x - 6.
Hence the slope is of:
m = 4.
Then the functions, relative to y = 4x - 6, are classified as follows:
Parallel: slope of 4.Perpendicular: slope of -1/4, as 4 x (-1/4) = -1.Neither: any slope different of 4 and of -1/4.Missing InformationThe problem gives three lines with different slopes, and you have to define if they are parallel, perpendicular or neither parallel nor perpendicular.
The intercepts are not relevant and I couldn't find the problem on the internet, hence I say that they are constants.
