The equation 4x + √y = 12 is a non-linear function because of the square root term. Non-linear functions do not have a constant rate of change and their graphs are not straight lines.
Explanation:The equation 4x + √y = 12 is not a linear function. A linear function is defined as a function that can be represented by a straight line. However, this equation contains a square root term, which makes it a non-linear function. To determine the type of function, it is important to consider the rules and properties of different function types.
In this case, the equation represents a non-linear function because of the square root term. Non-linear functions do not have a constant rate of change and their graphs are not straight lines. The square root term introduces a curve in the graph.
For example, let's say y = 4, then we can solve for x: 4x + √y = 12, which simplifies to 4x + 2 = 12. Solving for x, we get x = 2. So, for y = 4, x = 2. If we continue to substitute different values for y, we will see that the relationship between x and y is not linear.

on a map with a scale 1:100,000 the distance between two cities is 12cm. what would be the distance between these two cities on a different map with a scale 1:300,000?
Part 1)
we have
the scale is [tex]1:100,000[/tex]
the distance on a map is [tex]12\ cm[/tex]
we know that
The scale is equal to the distance on a map divided by the real distance
Let
x------> distance on a map
y-------> real distance
S-------> scale
[tex]S=\frac{x}{y}[/tex]
In this part we have
[tex]S=\frac{1}{100,000}[/tex]
[tex]x=12\ cm[/tex]
Find the value of y
[tex]y=\frac{x}{S}[/tex]
Substitute the values
[tex]y=\frac{12}{(1/100,000)}[/tex]
[tex]y=1,200,000\ cm[/tex]
Convert to kilometers
[tex]y=12\ Km[/tex]
Part 2)
In this part we have
[tex]S=\frac{1}{300,000}[/tex]
[tex]y=12\ km[/tex]
Find the value of x
[tex]x=S*y[/tex]
Substitute the values
[tex]x=(1/300,000)*12[/tex]
[tex]x=0.00004 Km[/tex]
Convert to centimeters
[tex]x=4\ cm[/tex]
therefore
the answer is
The distance is [tex]4\ cm[/tex]
The step function f(x) is graphed. What is the value of f(0)? -2 -1 0 1
Answer: -2 is the correct answer
Explanation:
This is the graph for greatest integer function by looking at the graph we can clearly conclude that f at zero is giving the value -2
Greatest integer function gives the value that is less than or equal to the value taken inside the function
For example if we have 2.09 and is operating under greatest integer function the value comes out to be 2 because it will convert the decimal value in integer
denoted as [2.09]=2

A hummingbird can travel up to 15 meters per second. What is the hummingbirds speed in miles per hour? 1 mile = 1609 meters
Answer:
33.56 miles per hour.
Step-by-step explanation:
First we will see how many meters the hummingbird can travel in an hour (in meters)
it can travel up to 15 meters per second, but we know that one hour has 3600 seconds ( because an hour has 60 minutes of 60 seconds each one ( 60 x 60 = 3600)
So the hummingbird can travel 3600 x 15 = 54,000 meters in one hour.
Now, we know that 1 mile = 1609 meters, so in order to convert the 54,000 meters in miles per hour we're going to use a rule of three.
1 mile ----------- 1609 meters
x miles ---------- 54,000 meters
x miles = 54,000/1,609 = 33.56
Therefore, the hummingbird speed is 33.56 miles per hour.

how much is 81% of 403? find the missing element in the following base-rate-percentage problem. round the answer to the nearest hundredth.
Find 81% of 403 by converting the percentage to a decimal (0.81) and then multiplying it by 403, which equals to 326.43 when rounded to the nearest hundredth.
Explanation:The student is asking for the solution to determine the value of 81% out of 403. This is a simple proportional math problem and could be solved with the following steps:
Convert the percentage (81%) to its decimal equivalent. This is done by dividing the percentage by 100. So, 81 divided by 100 equals 0.81.Multiply the given total number (403) by the decimal equivalent of the percentage. So, 0.81 times 403 equals 326.43.So, 81% of 403 is approximately 326.43, rounding to the nearest hundredth.

The word geometry has eight letters. Three letters are chosen at random. What is the probability that two consonants and one vowel are chosen?
Answer: [tex]\dfrac{15}{28}[/tex]
Step-by-step explanation:
The given word : geometry
Total letters in the above word = 8
Number of vowels (a e i o u) in word =3
Number of consonants = 5
Number of ways to choose two consonant and one vowel is given by :-
[tex]F=^5C_2\times^3C_1\\\\=\dfrac{5!}{2!(5-2)!}\times (3)\ [ \because ^nC_1=n]\\\\=5\times2\times3=30[/tex]
Number of ways to choose any three letters from the 8 alphabets:-
[tex]T=^8C_{3}=\dfrac{8!}{3!(8-3)!}=8\times7=56[/tex]
Now, the probability that two consonants and one vowel are chosen :-
[tex]=\dfrac{F}{T}\\\\=\dfrac{30}{56}=\dfrac{15}{28}[/tex]
Hence, the required probability = [tex]\dfrac{15}{28}[/tex]

Jeremy saves $35 per month over the first 7 months of the year. He saves $40 per month over the next 5 months of the year. If Jeremy spends none of his savings, which expression shows how many dollars he will have saved by the end of the year?
Answer: The expression shows the number of dollars he will have saved by the end of the year is given by [tex]35(7)+40(5)=\$445[/tex]
Step-by-step explanation:
Since we have given that
Amount he saved per month over the first 7 months = $35
Amount he saved per month over the next 5 months = $40
So, total saving by the end of the year is given by
[tex]35\times 7+40\times 5\\\\=\$245+\$200\\\\=\$445[/tex]
Hence, the expression shows the number of dollars he will have saved by the end of the year is given by
[tex]35(7)+40(5)=\$445[/tex]
Suppose that the sample space is s = {a, b, c, d, e, f, g, h} and that outcomes are equally likely. find the probability of the event e = {b, f, h}.
The probability of the event E = {b, f, h} with the sample space S = {a, b, c, d, e, f, g, h} is 3/8 or 0.375.
Explanation:The student has asked to find the probability of the event E = {b, f, h} given the sample space S = {a, b, c, d, e, f, g, h} where all outcomes are equally likely. To calculate the probability, we need to use the formula for theoretical probability, which is the number of favorable outcomes divided by the total number of possible outcomes in the sample space.
We see that the event E has 3 outcomes (b, f, h) and the sample space S has 8 outcomes. So the probability of event E is given by:
P(E) = Number of outcomes in E / Number of outcomes in S = 3 / 8 = 0.375

To rent a bike there is a set fee, plus an hourly rate. Renting a bike for 4 hours costs $24. Renting it for 7 hours costs $37.50. How much to rent it for 3 hours?
By solving a system of linear equations, the set fee for renting a bike is determined to be $6 and the hourly rate is $4.50. Hence, the cost to rent the bike for 3 hours is $19.50.
Explanation:The question involves creating linear equations based on the given information to find the cost of renting a bike for a certain number of hours. We are told that renting a bike for 4 hours costs $24 and renting for 7 hours costs $37.50. We can express this situation with two equations, where x represents the set fee and y represents the hourly rate:
4y + x = 247y + x = 37.5We solve this system of equations to find the values of x and y. Subtracting the first equation from the second gives us 3y = 13.5, hence y = 13.5 / 3 = $4.50 per hour. We can then substitute y back into the first equation: 4(4.50) + x = 24, which simplifies to 18 + x = 24, hence x = $6.
To rent the bike for 3 hours, the cost would be 3(4.50) + 6 = $13.50 + $6 = $19.50.

Why would the owner withdraw assets from other cash?
Answer:
The owner of a business sometimes withdraw assets other than cash because cash is more liquid and can be used in transactions easily, whereas the assets after a period of times becomes liable of depreciation.
The depreciation on assets decreases the amount of the assets based on the time and wear and tear of the tangible assets.
Therefore, to retain some liquid assets in hand the tangible or intangible assets are used first.

C. -12
D. 16
The result of evaluating the expression 4(2m-n)-3(2m-n) with respect to m=-15 and n=-18 is -12.
Explanation:To evaluate the expression 4(2m-n)-3(2m-n) for m=-15 and n=-18, we first substitute these given values into the expression.
Therefore, our expression becomes 4(2*(-15) - (-18)) - 3(2*(-15) - (-18)). Simplify the expression in the parentheses first according to the order of operations (also known as BEDMAS or PEMDAS) which stands for Brackets/parentheses, Exponents/Orders, Division/Multiplication, Addition/Subtraction.
4(2*-15 - (-18)) - 3(2*-15 - (-18)) simplifies to: 4(-30 +18) - 3(-30 + 18). Further simplify to: 4*-12 - 3*-12.
Then, doing the multiplication gets: -48 - (-36), which simplifies to: -48 + 36. Therefore, the value of the expression is -12.
