We are given a table of values for function f(x) as:
x y=f(x)
−3 −14
−2 −6
−1 −2
0 3
1 5
2 6
We know that the y-intercept of a function is a point where the x-value is zero.
i.e. the input value is zero.
Hence, after looking at the table of values of the function f(x) we have the y-intercept of the function f(x) is:
y=3
Also we are given function g(x) as:
g(x) = 3 cos(2x) + 1
Hence, we calculate the y-intercept of the function g(x) by taking x=0
on taking x=0 we have:
g(0)=3 cos(0)+1
g(0)=3+1=4
Hence, the y-intercept of function g(x) is 4.
Hence, g(x) has the greatest y-intercept.

Answer: 3.1
Step-by-step explanation:
The mean of the frequency distribution is 3.1. Which is the correct answer would be an option (B)
What is arithmetic mean?
Arithmetic mean is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean. One of the basic methods used to acquire a result, the term "Mean" is commonly used in the field of statistics.
The formula for the mean of a given set of data is as follows:
Mean = Sum of Observations/Total number of observations
Given the frequency distribution as :
Household size (x) Frequency (f) fx
1 2 1 × 2 = 2
2 4 2 × 4 = 8
3 6 3 × 6 = 18
4 5 4 × 5 = 20
5 2 5 × 2 = 10
Summation of fx = (Σfx) = 2 + 8 + 18 + 20 + 10 = 58
Total frequency = (Σf) = 2 + 4 + 6 + 5 + 2 = 19
⇒ Mean = Σfx/Σf
⇒ 58/ 19
⇒ 3.1
Thus, the mean of the frequency distribution is 3.1.

What is the midpoint of the x-intercepts of
f(x) = (x – 4)(x + 4)?
Answer:
midpoint is (0,0)
Step-by-step explanation:
the midpoint of the x-intercepts of
[tex]f(x) = (x - 4)(x + 4)[/tex]
To find the midpoint of x intercepts, we need to find the x intercepts first
we find x intercepts by replacing f(x) with 0
[tex]0 = (x - 4)(x + 4)[/tex]
Set each factor =0 and solve for x
[tex]x-4=0 , x=4[/tex]
[tex]x+4=0, x=-4[/tex]
X intercepts are -4 and 4
Midpoint of -4 and 4 is [tex]\frac{-4+4}{2} =0[/tex]
X intercepts lies on x axis . So midpoint is (0,0)
A boat traveled downstream a distance of 80 mi and then came right back. If the speed of the current was 7 mph and the total trip took 3 hours and 20 minutes, find the average speed of the boat relative to the water.
By converting the total trip time to minutes, using the formula for speed (distance/time), and using a system of equations representing the total trip speed when the boat is moving downstream and upstream, we can find the average speed of the boat relative to the water.
Explanation:To solve this problem, we first need to convert the total trip time to minutes to make calculations easier. Given in the problem, 3 hours 20 minutes equates to 200 minutes. Next, we should use the formula for speed, which is distance divided by time. We know that the total distance traveled by the boat is 80 miles downstream and 80 miles back, totaling 160 miles.
When moving downstream, the speed of the boat and the speed of the current both aid in the boat’s motion. Thus we have speed of the boat = speed of the boat in still water + speed of the current. However, when the boat is moving upstream, the speed of the current works against the boat's motion. Thus we have speed of the boat = speed of the boat in still water - speed of the current.
By using the system of these equations and the fact that total time equals total distance divided by the speed of the boat, we can find the speed of the boat in still water, which represents the average speed of the boat relative to the water.

Solve the system using the elimination method.
2x + y − z =9
−x + 6y + 2z =−17
5x + 7y + z =4
Whats x, y, and z???
Using the elimination method, the given system of equations leads to a solution of x = -1, y = 1, and z = -2.
Explanation:Solving the SystemThe first step in solving this system of equations using the elimination method is to try and eliminate one of the variables. Let's start with eliminating 'z' by adding the first and the third equation: [tex](2x + y - z) + (5x + 7y + z) = 7x + 8y = 13.[/tex]Now we can eliminate 'z' from the second equation as well by subtracting from it twice the first one:[tex]-(-x + 6y + 2z) - 2(2x + y - z) = -3x + 4y = -5.[/tex]Then we solve the new system of two equations: 7x + 8y = 13 and -3x + 4y = -5. Using substitution or elimination on this will give y = 1Substituting y = 1 into the equation -3x + 4y = -5 gives x = -1.Finally, substituting x = -1 and y = 1 into the first original equation 2x + y - z = 9 gives z = -2.

{(–5, –5), (–1, –2), (0, –2), (3, 7), (8, 9)}
Answer:
Option C is correct
Yes, the set of ordered pairs {(–5, –5), (–1, –2), (0, –2), (3, 7), (8, 9)} represents the function.
because every x-value corresponds to exactly one y-value.
Step-by-step explanation:
A function states that it is a relation in which every domain value is paired with exactly one element of range.
Given the set of ordered pair:
{(–5, –5), (–1, –2), (0, –2), (3, 7), (8, 9)}
Domain is all the x-values, and range is all the y-values.
Domain: {-5, -1, 0, 3, 8}
Range: {-5, -2, -2, 7, 9}
By definition:
each input value (i.e x values) is paired with exactly one element of y-value.
therefore,the set of ordered pairs {(–5, –5), (–1, –2), (0, –2), (3, 7), (8, 9)} represents the function.

How do write 21,070 in standard form
Final answer:
The number 21,070 is already in standard form. Standard form is a straightforward expression of a number as commonly written, without the need for scientific notation for simple numbers like this one.
Explanation:
The number 21,070 written in standard form is simply 21,070 itself. In mathematics, standard form refers to the way a number is commonly written. This number is already in standard form because it is expressed in a direct and straightforward manner. There is no need for further simplification or conversion. When numbers are very large or very small, they can be cumbersome to write out in full, which is why scientists and mathematicians may use scientific notation to express them.
For instance, if we had a larger number like 77,123,450, we could write it in scientific notation as 7.712345 × 10⁷, emphasizing that it is 7.712345 times ten to the seventh power.
For the provided number 21,070, no such conversion is necessary, and it remains 21,070 in standard notation.
Given line L = ax + by + c = 0, b 0 What is the x-intercept? y-intercept?
Answer:
On Odyssey ware it is -c/a
Step-by-step explanation:
The x-intercept and the y-intercept of a line can be found by setting y and x to zero in the line equation respectively. The x-intercept is -c/a and the y-intercept is -c/b.
Explanation:To find the x and y-intercepts of the given line equation L = ax + by + c = 0, we must set one variable to zero and solve for the other.
To find the x-intercept of a line, we can set y to zero (as this is the case when the line crosses the x-axis), we get:
L = ax + b(0) + c = 0 or x = -c/a
Therefore the getX-intercept of the line is -c/a.
Similarly to find the y-intercept of the line equation, we can set x to zero (as this is the case when the line crosses the y-axis), we get:
L = a(0) + by + c = 0 or y = -c/b
Hence, the y-intercept of the line is -c/b.
