Consider the following function.
r(x)=4−32x
Step 2 of 2 : Find two points on the line to graph the function.
Answers
We can plot (0, 4) and (1, -28) points on a coordinate plane and draw a straight line passing through both points to graph the function.
What is a coordinate plane?
A coordinate plane, also known as a Cartesian plane, is a two-dimensional plane that is used to plot points and graph mathematical equations. It consists of two perpendicular number lines called the x-axis and the y-axis. The x-axis is the horizontal line, with positive values to the right of the origin (0) and negative values to the left of the origin. The y-axis is the vertical line, with positive values above the origin and negative values below the origin. The x-coordinate gives the horizontal position of the point, and the y-coordinate gives the vertical position of the point. By plotting points on a coordinate plane, we can graph lines, curves, and other mathematical functions. It is a fundamental tool in mathematics, science, and engineering for visualizing and analyzing relationships between variables.
To find two points on the line of the function r(x) = 4 - 32x, we can simply choose any two values of x and find the corresponding values of r(x).
For example, when x = 0:
r(0) = 4 - 32(0) = 4
So one point on the line is (0, 4).
When x = 1:
r(1) = 4 - 32(1) = -28
So another point on the line is (1, -28).
Therefore, we have two points on the line: (0, 4) and (1, -28).
We can plot these points on a coordinate plane and draw a straight line passing through both points to graph the function.

Five lemonades and two cookles cost $1.50. Two lemonades and five cookles cost $2.70. How much does one cookle and one lemonade cost?
Answers
Answer:
50¢/cookie, $1.00/lemonade
Step-by-step explanation:
Let l = cost of one lemonade
c = cost of one cookie
We have:
5l + 2c = 1.50 -------> 10l + 4c = 3.00
2l + 5c = 2.70 -------> 10l + 25c = 13.50
-----------------------
21c = 10.50
c = .50
5l + 2(.50) = 1.50
5l + 1.00 = 1.50
5l = 5, so l = 1.00
Each cookie costs 50¢, and each lemonade costs $1.00.
If 80% of a number is 304 and 15% of the same number is 57, find 95% of that number.
Answers
Answer:
95% of that number is 361
Step-by-step explanation:
Let's start by finding the actual value of the number.
If 80% of a number is 304, we can set up the equation:
0.8x = 304
To solve for x, we can divide both sides by 0.8:
x = 380
So the number is 380.
Now we can use the second piece of information to find 15% of the number:
0.15(380) = 57
This confirms that our value for x is correct.
Finally, we can use this information to find 95% of the number:
0.95(380) = 361
Therefore, 95% of the number is 361.

A graph: what is it?A graph is a visual representation or diagram that displays facts or values in an organized manner in mathematics.
The red graph is represented by the function:
f(x)=x²
Also, we need the formula for the blue graph.
We can see that the blue graph is just the red graph with the horizontal axis moved 2 units to the right.
An example of a horizontal transition is:
f(x-h) where h is the quantity we shift (to the right).
h = 2 since we moved two units to the right.
Our new role will thus be:
g(x)=f(x-2)=(x-2)²
Therefore:
g(x)=(x-2)²
Our response is B.
Notes:
A denotes a downward vertical movement of two units.
C (assuming it is x²) denotes a two-unit vertical displacement upward.
And D (if you let h = -2, then f(x - (-2)) = f(x + 2) = (x + 2)²) is a horizontal shift of two units to the left.

To qualify for a police academy, candidates must score in the top 10% on a general abilities test. The test has a mean of 200 and a standard deviation of 20. Find the lowest possible score to qualify. Assume the test scores are normally distributed.
Can someone give a step by step explanation on how to find the Z score? I know how to find X but I need help with mostly Z.
Answers
So the lowest possible score to qualify for the police academy is 225.6.
What is mean?In statistics, the mean is a measure of central tendency that represents the average value of a set of data. It is calculated by adding up all the values in the data set and then dividing by the total number of values.
Here,
To find the Z-score, you will need to use the following formula:
Z = (X - μ) / σ
where:
X = the raw score you are trying to find
μ = the population mean (in this case, 200)
σ = the population standard deviation (in this case, 20)
To find the lowest possible score to qualify, you need to find the score that corresponds to the 90th percentile (i.e., the top 10%).
To do this, you can use a standard normal distribution table or a calculator that has a normal distribution function.
Here are the steps:
Find the Z-score that corresponds to the 90th percentile.
You can use a standard normal distribution table to find this value. Look for the row that corresponds to the first digit(s) of the percentile (in this case, 9) and the column that corresponds to the second digit (in this case, 0.0). This will give you the Z-score that corresponds to the 90th percentile, which is approximately 1.28.
Alternatively, you can use a calculator that has a normal distribution function. For example, in Excel, you can use the formula =NORM.S.INV(0.9) to find the Z-score that corresponds to the 90th percentile.
Plug in the values for μ, σ, and Z into the formula for Z-score:
Z = (X - μ) / σ
Rearranging the formula, we get:
X = Z * σ + μ
Substituting the values we know, we get:
X = 1.28 * 20 + 200
X = 225.6

Answers
Answer: The interest rate per quarter is 5%/4 = 1.25%.
At the end of the first quarter, the balance is:
$1000 + $1000(1.25%) = $1000 + $12.50 = $1012.50
At the end of the second quarter, the balance is:
$1012.50 + $1012.50(1.25%) = $1012.50 + $12.66 = $1025.16
At the end of the third quarter, the balance is:
$1025.16 + $1025.16(1.25%) = $1025.16 + $12.82 = $1037.98
At the end of the fourth quarter, the balance is:
$1037.98 + $1037.98(1.25%) = $1037.98 + $13.00 = $1050.98
Therefore, the year-end balance is $1050.98 (rounded to the nearest penny).

the lowest form of 28 upon 36 is ........... ( with explanation pls)
Answers
Answer:
To find the lowest form of 28 upon 36, we need to simplify or reduce the fraction to its lowest terms. This can be done by finding the greatest common factor (GCF) of the numerator (28) and the denominator (36) and dividing both by it.
First, we can find the prime factors of 28 and 36:
28 = 2 × 2 × 7
36 = 2 × 2 × 3 × 3
Next, we can identify the common factors, which are 2 and 2.
To find the greatest common factor, we need to multiply the common factors together. In this case, 2 × 2 = 4, so the greatest common factor is 4.
Now we can divide both the numerator and the denominator by the GCF:
28 ÷ 4 = 7
36 ÷ 4 = 9
Therefore, the lowest form of 28 upon 36 is 7/9.

Answers
The sequence generated by the formula f(n) = (4n - 7) starting with n = 1 is: -3, 1, 5, 9, 13
What is functions?A function is typically denoted by a symbol, such as "f(x)", where "x" is the input value and "f(x)" is the output value. The input value is sometimes referred to as the "argument" of the function.
The formula f(n) = (4n - 7) generates a sequence of numbers when we plug in different values of "n". To generate the terms f(1), f(2), f(3), f(4), f(5) we need to substitute each value of n into the formula and evaluate the expression.
Starting with n = 1, we can generate the terms as follows:
f(1) = (4 × 1 - 7) = -3
f(2) = (4 × 2 - 7) = 1
f(3) = (4 × 3 - 7) = 5
f(4) = (4 × 4 - 7) = 9
f(5) = (4 × 5 - 7) = 13
So the sequence generated by the formula f(n) = (4n - 7) starting with n = 1 is: -3, 1, 5, 9, 13
Each term in the sequence is found by plugging in a different value of "n" into the formula f(n) = (4n - 7). The first term, f(1), is found by plugging in n = 1, the second term, f(2), is found by plugging in n = 2, and so on.

He could survey the first 25 women and 25 men he met at a grocery store, survey every 10th woman and every 10th man from a list of people living in the town, survey one person from every 10th home in the town, or survey the first 50 people he saw at the airport as he got off the plane.Each of these methods would result in a sample of 50 people that is randomly selected from the population of 500 residents. This would ensure that the sample is representative of the population and that the results of the survey are not biased in any way. Furthermore, the sample size of 50 is large enough to be considered representative of the population of 500.

6 typists working 5 hours a day can type the manuscript of a book in 16 days. How many days will 4 typists take to do the same job? each working 6 hours a day?
Answers
Answer:
Let's begin by finding the total work required to complete the manuscript of the book:
Total work = (Number of typists) x (Number of hours per day) x (Number of days) = 6 x 5 x 16 = 480
Now let's find the work done by 4 typists working 6 hours per day:
Work done by 4 typists = (Number of typists) x (Number of hours per day) x (Number of days) = 4 x 6 x d
where d is the number of days required to complete the manuscript.
Since the amount of work done is the same in both cases, we can set the two equations equal to each other and solve for d:
6 x 5 x 16 = 4 x 6 x d
Simplifying this equation, we get:
480 = 24d
Dividing both sides by 24, we get:
d = 20
Therefore, it will take 4 typists working 6 hours per day a total of 20 days to complete the manuscript of the book.

reagan wanted to paint so she invested $500 several years later,she has earned $2000 in interest. how long did reagan invest the money if she earned a simple interest rate of 5% ?
Answers
Regan invested the money for 8 years at simple interest to earn $2000.
What is the difference between simple interest and compound interest?Simple interest is calculated on the loan amount or principle amount, whereas compound interest is calculated using both the principal amount and the interest that has accrued over the course of a prior period or particular time. Simple interest is based on the principal amount, which is the main distinction between it and compound interest. Contrarily, compound interest is calculated using the principle sum and interest that has been compounded over the course of a period.
The simple interest is given as:
SI = Prt
where I is the interest earned.
P is the principal, = 500.
is the interest rate = 5% = 0.05.
t is the time (in years).
Substituting the values:
2000 = 500 * 0.05 * t
t = 8 years
Hence, Regan invested the money for 8 years at simple interest to earn $2000.

opposite directions. From point A, the crew
of boat A (red boat) measures the angle of
elevation to the top of the lighthouse as 45°.
On the other hand, from point B, the crew
of boat B (green boat) measures the angle
of elevation to the top of the lighthouse as
30°. The lighthouse is at a height of 300 ft
above the water.

a) How far is boat A from the
lighthouse? (the horizontal distance)
b) How far is boat B from the
lighthouse? (the horizontal distance)
c) And hence, find the total horizontal
distance between the two boats.
Answers
Hypotenuse equals opposite/tan(45°) = 300/1 = 300 feet. Boat A is therefore 300 feet horizontally away from the lighthouse.
what is distance ?The numerical measurement of distance is the separation between two objects or points. Typically, it is expressed in terms of metres, kilometres, miles, or feet. Distances can be calculated either along a simple path (the Euclidean distance) or along a more complicated one (such as a curved surface or a circuitous route). Distance is a crucial notion that is used to define the separation between things, the length of a route or path, and the displacement of an object through time in many disciplines, including physics, mathematics, geography, and engineering.
given
We may utilise trigonometry and create some equations based on the provided angles and distances to solve this problem.
a) We can use the tangent function to calculate the separation between boat A and the lighthouse:
opposite/hypotenuse = tan(45°)
where the hypotenuse is the distance between boat A and the lighthouse, the other side is the lighthouse's height (i.e., the horizontal distance we want to find). By calculating the hypotenuse, we obtain:
Hypotenuse equals opposite/tan(45°) = 300/1 = 300 feet. Boat A is therefore 300 feet horizontally away from the lighthouse.
