The equation 2x + 3y = 16 has infinitely many solutions.
We know that a linear equation in two variables is of the form ax + by + c = 0, where a, b, c are non-zero real numbers.
Here we have been given a linear equation in two variables 2x + 3y = 16
We solve this equation for x,
Consider 2x + 3y = 16
2x + 3y - 3y = 16 - 3y .........(subtract 3y from each side of equation)
2x/2 = (16 - 3y)/2 .........(divide each side by 2)
x = (16 - 3y)/2
for any real value of y we can find value of x.
This means, an equation 2x + 3y = 16 has infintely many solutions.
For x = 0,
2(0) + 3y = 16
y = 16/3
y = 5.333
This means, the y-intercept of line 2x + 3y = 16 is (0, 5.333)
For y = 0 ,
2x + 3(0) = 16
x = 16/2
x = 8
This means, the x-intercept of line 2x + 3y = 16 is (8, 0)

About one through 2% of the population ha red hair. If 800 people were randomly ampled about how many of them would you expect to be redhead?
We would expect about 16 people in a sample of 800 people to be redheads, give or take some random variation.
What is probability ?
Probability is the measure of the likelihood of an event occurring. It is a number between 0 and 1, with 0 indicating that an event is impossible and 1 indicating that an event is certain. Probability can be expressed as a fraction, decimal, or percentage. For example, a probability of 0.5 is the same as a probability of 1/2 or 50%.
The probability of an event can be calculated by counting the number of favorable outcomes and dividing by the total number of possible outcomes.
If 2% of the population has red hair, we can expect 2 out of every 100 people in the population to be redheads. To find out how many redheads we would expect in a sample of 800 people, we can use this proportion and multiply it by the number of people in the sample.
2/100 * 800 = 16
So, we would expect about 16 people in a sample of 800 people to be redheads, give or take some random variation.

Why are the values for sine and cosine equal at 45?.
Answer: In an equilateral triangle, the hypotenuse and its opposite side are equal
By the way, I am human. There is too many bot answers.
The values for sine and cosine are equal at 45 degrees because they are related to the right triangle formed by the angle.
In a right triangle, the sine of an angle is equal to the length of the side opposite the angle divided by the length of the hypotenuse. The cosine of an angle is equal to the length of the adjacent side divided by the length of the hypotenuse.
When the angle is 45 degrees, the triangle formed is a 45-45-90 triangle, this is a special triangle in which all the angles are 45 degrees and all the sides are in the ratio of 1:1:√2.
In this triangle, the hypotenuse is √2 times the length of either leg. So, the sine of 45 degrees is opposite/hypotenuse = (1/√2) and the cosine of 45 degrees is adjacent/hypotenuse = (1/√2). Since the opposite and adjacent sides are of the same length in the 45-45-90 triangle, the sine and cosine of 45 degrees are equal.
So, sine 45 = cosine 45 = 1/√2.

There are 5280 feet in a mile and about 3.28 feet in a meter. Given that sound travels about 343 meters per second what’s is the distance in miles from alyssa to the lighting bolt
Answer: We know that sound travels about 343 meters per second. To convert the distance in meters to miles, we need to use the conversion factor that there are 3.28 feet in a meter and 5280 feet in a mile.
1 mile = 5280 feet = 5280/3.28 meters = 1600 meters
Therefore, the distance in miles from Alyssa to the lightning bolt can be calculated by dividing the distance in meters by the number of meters per mile:
distance in miles = distance in meters/1600
So, the distance in miles from Alyssa to the lightning bolt is 343 meters/1600 miles = 0.215 miles (approx)
Note that this calculation is based on the assumption that sound travels 343 meters per second and it's an approximation.

The form of function is a logarithmic function. either "y equals the log of x, base b" or "y equals the log, base b, of x."
What is logarithmic function?
An exponential function's inverse is a logarithmic function. An exponential function's basis is the same as that of a log function. Exponents include logarithms. f(x) = bx is the formula for the exponential function. f(x) = log base b of x is how the logarithmic function is expressed.
The expression "y equals the log of x, base b" or "y equals the log, base b, of x" is the definition of a logarithmic function. In both cases, b > 0, b 1, and x > 0. There are no limitations on y. logarithm, the exponent or power that a base must be increased to in order to get a specific number. If bx = n, then mathematically, x is the base-b logarithm of n.
Determine the logarithmic function of the provided graph by using the provided points in the following manner:
[tex]f(x) = log_a(x-h)[/tex]
Create two equations by substituting the provided points (3/2, 1) and (3, -1) into the formula:
[tex]log_a(\frac{3}{2}-h) = 1[/tex]
[tex]log_a({3}-h) = -1[/tex]
To isolate a, use the log law and rearrange each equation:
[tex]log_a(\frac{3}{2}-h) = 1[/tex]
⇒ [tex]a^1 = (\frac{3}{2}-h)[/tex]
⇒1/a = 3 - h
⇒ a = 1/ [tex]\frac{3}{2}[/tex] - h ....................................(1)
[tex]log_a({3}-h) = -1[/tex]
⇒[tex]a^{-1} = ({3}-h)[/tex]
⇒ 1/a = 3-h
⇒ a = 1/3-h ..............................................(2)
Solve for h:
⇒ 3/2 - h = 1/3-h
⇒ 3-2h/2 = 1/3-h
⇒ 9 - 9h + 2h^2 = 2
⇒(2h-7)(h-1) = 0

What is vertex form of a quadratic equation?.
The vertex form of a quadratic equation is written as y = a(x-h)^2 + k, where (h,k) is the vertex of the parabola and a is the leading coefficient.
The vertex form can be converted from the standard form (y = ax^2 + bx + c) by completing the square and shifting the parabola horizontally and vertically.
The vertex form of a quadratic equation is y = a(x-h)^2 + k, where (h,k) is the vertex of the parabola, which is the lowest point for a parabola that opens upwards, and highest point for a parabola that opens downwards. The "a" coefficient is the leading coefficient which represents the direction of the parabola, whether it opens upwards or downwards. The vertex form is useful in identifying the vertex of the parabola and its symmetry axis, as well as its direction.
So, the vertex form of a quadratic equation is written as y = a(x-h)^2 + k, where (h,k) is the vertex of the parabola and a is the leading coefficient.

The weight of the cashews plus the weight of the peanuts cannot be more than 192 ounces and the weight of the cashews must be at least one-fourth of the total weight of the mixture.
Step 1: Let c = weight of cashews
Step 2: Let p = weight of peanuts
Step 3: 0.25c + p ≤ 48
Step 4: Multiply both sides by 4
Step 5: 4(0.25c + p) ≤ 4(48)
Step 6: c + p ≤ 192
This system of inequalities models the situation of combining cashews and peanuts to make a nut mixture. The first inequality states that the weight of the cashews plus the weight of the peanuts cannot exceed 48 ounces, and the second inequality states that the weight of the cashews must be at least one-fourth of the total weight of the mixture. To model this situation, we let c equal the weight of the cashews and p equal the weight of the peanuts. We then multiplied both sides of the first inequality by four to get the second inequality, which states that the weight of the cashews plus the weight of the peanuts cannot exceed 192 ounces. This system of inequalities accurately models the situation of combining cashews and peanuts to make a nut mixture, and it ensures that the weight of the cashews is at least one-fourth of the total weight of the mixture.

Nelly works at an hourly rate of $11. 28 per hour and worked 45 hours last week. She earns overtime for hours exceeding 40 hours. She is paid overtime at a rate of time and a half. What was her gross pay last week?.
Nelly's gross pay is $451.20 + $84.60 = $535.80.
Gross pay refers to the total amount of money an employee earns before any deductions or taxes are taken out. It is the total amount of money earned by an employee for the hours worked, including any overtime or bonuses.
First, we calculate her regular pay.
She worked 45 hours last week, and her regular hourly rate is $11.28 per hour. Therefore, her regular pay for the week is 40*$11.28 = $451.20. This is the pay she receives for the hours she worked up to 40 hours, which is considered the standard workweek.
Next, we calculate her overtime pay. Nelly worked 45 hours last week, and she is entitled to overtime pay for hours exceeding 40 hours. Therefore, she worked 45-40 = 5 hours of overtime.
Since she is paid time and a half for overtime, her overtime pay is calculated by multiplying her regular hourly rate by 1.5. Therefore, her overtime pay is 5*$11.28*1.5 = $84.60.
Finally, we add her regular pay and her overtime pay to get her gross pay. Her gross pay is the total amount she earns for the week, including both her regular pay and her overtime pay.
Therefore, her gross pay is $451.20 + $84.60 = $535.80.

Can someone help me on this and show me how to do it like show the work
Answer:
381 feet
Step-by-step explanation:
You are 220 ft from a tree whose top you see at a 60° angle of elevation. You want to know the height of the tree.
TangentThe tangent relation between sides of a right triangle is ...
Tan = Opposite/Adjacent
where "opposite" and "adjacent" refer to the sides opposite and adjacent to the acute angle of interest.
ApplicationHere, the 60° angle of elevation is adjacent to the 220 ft distance from the tree, and opposite the height of the tree. This means ...
tan(60°) = height/(220 ft)
Multiplying by 220 ft, we find the height to be ...
height = (220 ft)tan(60°) = 220√3 ft ≈ 381 ft
The tree is 381 feet tall.
__
Additional comment
The triangle that models this geometry is a 30°-60°-90° right triangle, one of the "special" right triangles that often shows up in geometry and trigonometry problems. Its side lengths have the ratio 1 : √3 : 2. Knowing this, you know the tree height is √3 times the distance from the tree:
220√3 ft
Your calculator can tell you this is about 381 feet.
To find the height of the tree, we can use the tangent function, which relates the opposite side (the height of the tree) to the adjacent side (the distance from the tree) and the angle. The formula is:
Why is it referred to as a tangent function?
Tangent is derived from the Latin verb tangere, which means "to touch." A circle has one point where a line that is tangent to it intersects.
tangent(angle) = opposite / adjacent
In this case, the angle is 60 degrees, the opposite side is the height of the tree, and the adjacent side is the distance from the tree, which is 220 feet. So we can write:
tan(60) = height / 220
To find the height, we can divide both sides by the tangent of 60 degrees:
height = 220 * tan(60)
The exact value of the height of the tree is not possible to be obtained with the given information, the height of the tree is a number in the infinite set of real numbers.
We can use a calculator or a table of tangents to find an approximate value of the height.
It could be around 379.3 ft.

Function in math is known as a correspondence from one value x of the first set A to another value y of the second set B.
Here we need to identify the way to know that whether the given unction is inverse function or not.
By using the horizontal line test that is If any horizontal line intersects the graph of f more than once then the function f does not have an inverse.
Where as If no horizontal line intersects the graph of f more than once, then the function f does have an inverse.
Here we have also have the property of having an inverse is very important in mathematics, and it has a name.

For what value of k does the system of equations kx 2y 5 and 3x 4y 10 have no solution?.
Hence value of k does the system of equations k x +2y= 5 and 3x - 4y =10 have no solution[tex]\frac{-3}{2}[/tex]
The given system of equations:
k x + 2y = 5
⇒ k x + 2y - 5 = 0 ….( i)
3x - 4y = 10
⇒3x - 4y - 10 = 0 …(ii)
These equations are of the forms:
a1x + b1y + c1 = 0
a2x + b2y + c2 =0
where, a1 = k
b1 = 2
c1 = -5
a2= 3
b2 =-4
c2 = -10
[tex]\frac{a1}{a2} \neq \frac{b1}{b2}[/tex]
[tex]\frac{k}{3} \neq \frac{2}{-4}[/tex]
[tex]k\neq \frac{-3}{2}[/tex]
Thus for all real values of k other than −3/2 ,
the given system of equations will have a unique solution.
(ii) For the given system of equations to have no solutions, we must have:
[tex]\frac{a1}{a2} = \frac{b1}{b2}\neq \frac{c1}{c2} \\\\ \frac{k}{3} = \frac{2}{-4}\neq \frac{-5}{-10} \\ \\ \frac{k}{3} = \frac{2}{-4}\\ \\ \frac{k}{3} \neq \frac{1}{2} \\ \\ \\k \neq \frac{3}{2} \\\\k =\frac{-3}{2} \\[/tex]
Hence value of k does the system of equations k x +2y= 5 and 3x - 4y =10 have no solution[tex]\frac{-3}{2}[/tex]

please help with this coordinates question
Answer:
Coordinates of C are (22, 20)
Step-by-step explanation:
We can see the squares are identical
The x-distance between A and B is 38 - 6 = 32
This covers 4 squares so each square side length = 32/4 = 8
Since point C is two squares away, the x-coordinate of C is 8 x 2 = 16 units away from the A x coordinate
x-coordinate of C = x-coordinate of A + 16 = 6 + 16 = 22
So x-coordinate of C is 22
To find the y-coordinate of C, because it is a square each vertical side of the square is also 8 units
If the third square were aligned with the top right of the second square, the y-coordinate of that square should be :
y-coordinate of A + 2 x 8 = 7 + 16 = 23
In this case, the y-coordinate of B should have been 23 + 2 x 8 = 23 + 16 = 39
However, because of the downward shift of the third square, the y-coordinate of B is only 36
39-36 = 3
So the third square has been shifted down by 3
Therefore y coordinate of C = 23 - 3 = 20
Coordinates of point C: (22, 20) which will result in the figure shown.
Just to verify
Since point B is 16 units to the right of C, its x-coordinate = 22 + 16 = 38
Point B
Point B y-coordinate is 16 units vertically up from y-coordinate of C.
So y-coordinate of B = 20 + 16 = 36
Hence verified
I hope that makes sense.
The attached figure shows exactly the figure in the question but with the coordinates marked. You can independently verify this
