Lines m and p are perpendicular. If the slope of line m is -3, what is the slope of line p?
Answer: The slope of p is 1/3
Step-by-step explanation:
If the lines are perpendicular, this means they are opposite.
Thus, O is opposite P and since O = -3, P = 1/3

Sequence of numbers is collection of ordered numbers. The given sequence is described by formula:
What is a geometric sequence and how to find its nth terms?There are three parameters which differentiate between which geometric sequence we're talking about.
The first parameter is the initial value of the sequence.
The second parameter is the quantity by which we multiply previous term to get the next term.
The third parameter is the length of the sequence. It can be finite or infinite.
Suppose the initial term of a geometric sequence is and the term by which we multiply the previous term to get the next term is
Then the sequence would look like
(till the terms to which it is defined)
Thus, the nth term of such sequence would be
Tn = ad^n-2
For the given sequence, it can be seen that each term is divided by 3 to get the next term. We can take it as we're doing multiplication by 1/3
Thus, the given sequence is geometric sequence and its characteristics are:
Thus, ith term is given as:
Ti = 27/3^i-2
We write sequence as: {an}b_c
where n starts with value b and runs integer values and end up on n = c
For this case, we've n = 1 to 5, thus,
The given sequence is written as:
{27/3^n-1 }5_1
Thus,
The given sequence is described by formula: {27/3^n-1 }5_1

Write the equation of the line for the graph shown below, please
Answer:
Given the proposed interrogate, as well as the graph provided, the correct answer is B. Y = 1/2 x + 4
Step-by-step explanation:
To evaluate such, a comprehension of linear Cartesian planes are obligated:
Slopes = rise/run
X- intercept: The peculiar point in which linear data is observed to intersect the x-axis.
Y- intercept: The peculiar point in which linear data is observed to intersect the y-axis.
Slope: 1/2 as for every individual space endeavored, a space of 2 to the right is required.
Y- intercept: (4,0)
Thus, the ameliorated answer to such interrogate is acknowledged as B. Y = 1/2 x + 4.
*I hope this helps.
For this question it’s asking for it in slope intercept form. So all you need to find is the slope and the y intercept.To find the y int look at where the line passes y. In this case it is y=4, then find slope by finding change in y/ change once which is 1/2, so you get y=1/2x+4
Tom and Carl start 200 miles apart, running towards each other. Tom runs 5 miles per hour faster than Carl. If they meet after 10 hours, how fast are they running?
Answer:
12.5 mph and 7.5 mphStep-by-step explanation:
Tom's speed = xCarl's speed = yWe have:
x = y + 5(x + y)*10 = 200Substitute x and solve for y:
(y + y + 5)*10 = 2002y + 5 = 202y = 15y = 7.5Find x:
x = 7.5 + 5 = 12.5Tom's speed is 12.5 mph
Carl's speed is 7.5 mph
Now
a=b+510(a+b)=200From eq(2)
a+b=20From eq(1)
a-b=5Adding these recent two
2a=25a=12.5mphPutting in eq(1)
b=a-5b=12.5-5b=7.5mphthe expectation students often have when doing the coin flip experiment is that thye will flip exactly 5 heads and 5 tails because there is 50% chance of flipping each. Is this a realistic expectation
Answer:
No
Explanation:
A coin which has a head and a tail has 1/2 probability of each which is a 50% chance of getting either a head or a tail. This means that given two sides of a coin, probability looks at the number of favorable outcomes and total number of outcomes, a formula that reflects a pattern seen in past experiences. Probability isn't absolute but relative. When we say there is a 50% chance of getting a head in a coin flip, it is relative to past experiences but doesn't assure of particular future occurrences regarding the coin flip.

Answer:
b = -13/3
Step-by-step explanation:
Plug in the 13/3 into the t and then try to solve it. Like this:
(13/3 - 8/3)(13/3 + b) = 0 ----> 5/3(13/3+b) = 0 ----> from here you have to distribute ----> 65/9 + b = 0 (here you have to subtract from both sides)
b = -65/9 (you could simplified) ---> b = -13/3
Identify two linear correlations and two curvilinear correlations not mentioned in either the text or the lecture. What is the relationship between the variables
Answer and explanation:
Linear correlation is relationship between two variables, negative or positive. When there is a negative linear correlation between two variables, one variable increases steadily while the other decreases in same proportion. In positive linear correlation, two variables increase or decrease in steadily on same proportion.
Curvilinear correlation is relationship between variables that occurs when two variables increase steadily at same rate but at some point one begins to decrease while the other increases.
Two examples of linear correlation are : increase in work hours and increase in pay cheque
increase in expenses and decrease in cash
Two examples of curvilinear correlation are:
increase in staff cheerfulness and customer satisfaction but to certain extent
increase in achievements and increase in anxiety but to certain point when achievements begin to decrease.

Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 29 problems. Each problem is
worth either 5 points or 2 points. Write a system of equations that can be used to find how many problems of each
point value are on the test.
Let x be the number of questions worth 5 points and let y be the number of questions worth 2 points.
O x + y = 29, 5x + 2y = 100
Ox+y = 100, 5x + 2y = 29
O 5x + y = 29, 2y + x = 100
O 2x + y = 100, 5y + x = 29
Answer:
x + y = 29, 5x + 2y = 100
Step-by-step explanation:
First, create an equation based on how there are 29 problems on the test.
x + y represents all of the questions on the test, so it should be set equal to 29.
The first equation is x + y = 29.
Now, create an equation based on how the test is worth 100 points.
5x will represent the points from the questions worth 5 points, and 2y will represent the points from the questions worth 2 points.
These terms will be added together, and set equal to 100.
The second equation is 5x + 2y = 100.
So, the system of equations is x + y = 29, 5x + 2y = 100
It is known that a
a) add 4 to both sides of the inequality
b) multiply each side of the inequality by 8
PLEASE HELP NEED ASAPPPP WILL GIVE BRAINLIEST TO FIRST CORRECT ANSWER
Answer:
the answer is B
Step-by-step explanation:
Multiplying or dividing both sides by a negative number reverses the inequality. This means < changes to >, and vice versa. For example, given that 5 < 8 we can multiply both sides by 6 to obtain 30 < 48 which is still true. −30 > −48, which is a true statement.
when solving inequalities with absolute values When solving an inequality: • you can add the same quantity to each side • you can subtract the same quantity from each side • you can multiply or divide each side by the same positive quantity If you multiply or divide each side by a negative quantity, the inequality symbol must be reversed.

According to the Fundamental Theorem of Algebra, which polynomial function has exactly 8 roots?
PLS HELP IM TIMED
Answer:
Option (1)
Step-by-step explanation:
Fundamental theorem of Algebra states degree of the polynomial defines the number of roots of the polynomial.
8 roots means degree of the polynomial = 8
Option (1)
f(x) = (3x² - 4x - 5)(2x⁶- 5)
When we multiply (3x²) and (2x⁶),
(3x²)(2x⁶) = 6x⁸
Therefore, degree of the polynomial = 8
And number of roots = 8
Option (2)
f(x) = (3x⁴ + 2x)⁴
By solving the expression,
Leading term of the polynomial = (3x⁴)⁴
= 81x¹⁶
Therefore, degree of the polynomial = 16
And number of roots = 16
Option (3)
f(x) = (4x² - 7)³
Leading term of the polynomial = (4x²)³
= 64x⁶
Degree of the polynomial = 6
Number of roots = 6
Option (4)
f(x) = (6x⁸ - 4x⁵ - 1)(3x² - 4)
By simplifying the expression,
Leading term of the polynomial = (6x⁸)(3x²)
= 18x¹⁰
Degree of the polynomial = 10
Therefore, number of roots = 10
