fifteen points, no three of which are collinear, are given on a plane. how many lines do they determine?
Answers
15 non-collinear points on a plane determine 105 lines
To find the number of lines determined by 15 non-collinear points on a plane, we can use the combination formula. The combination formula is written as C(n, k) = n! / (k!(n-k)!), where n is the total number of elements and k is the number of elements we want to choose from the total.
In this case, we have 15 points (n = 15) and we need to choose 2 points (k = 2) to form a line. Applying the combination formula:
C(15, 2) = 15! / (2!(15-2)!) = 15! / (2! * 13!) = (15 * 14) / (2 * 1) = 105
Therefore, 15 non-collinear points on a plane determine 105 lines.

Answers
The unit vector in a direction of zero change with a positive x-component is (1/√17) i - (4√2/√17) j.
To find the directions in the xy-plane in which the function f(x,y) = 7 - 4x² - 2y² has zero change at the point P(1,-1,1), we will find the gradient of the function and then plug in the given point and solve for the unit vectors in the xy-plane. Answer:Part 1:Gradient of the function f(x, y) = 7 - 4x² - 2y² is:∇f(x, y) = (-8x, -4y) At the point P(1, -1),
we have∇f(1,-1) = (-8, 4)To find the directions in the xy-plane in which the function f(x,y) = 7 - 4x² - 2y² has zero change at the point P(1,-1,1), we need to solve the equation ∇f(1,-1) . (a, b) = 0, where (a, b) is the direction vector in the xy-plane. This gives us:∇f(1,-1) . (a, b) = -8a + 4b = 0⇒ b = 2a
We also know that the direction vector (a, b) should be a unit vector, so |(a, b)| = 1. Substituting b = 2a and |(a, b)| = 1, we get:√(a² + b²) = √(a² + (2a)²) = √(5a²) = 1⇒ a = 1/√5 and b = 2/√5.
Therefore, the two directions in the xy-plane in which f(x,y) = 7 - 4x² - 2y² has zero change at P(1,-1,1) are (1/√5, 2/√5) and (-1/√5, -2/√5) respectively, and in terms of unit vectors, they are: (1/√5) i + (2/√5) j and (-1/√5) i - (2/√5) j.

simplify (1-cos x)(1+cos x)
Answers
Answer:
\(sin^2x\)
Step-by-step explanation:
To simplify the expression (1 - cos x)(1 + cos x), we can use the difference of squares identity, which states that \(a^2 - b^2 = (a + b)(a - b).\)
Let's apply this identity to the given expression:
\((1 - cos x)(1 + cos x) = 1^2 - (cos x)^2\)
Now, we can simplify further by using the trigonometric identity \(cos^2(x) + sin^2(x) = 1.\) By rearranging this identity, we have \(cos^2(x) = 1 - sin^2(x).\)
Substituting this into our expression, we get:
\(1^2 - (cos x)^2 = 1 - (1 - sin^2(x))\)
Simplifying further:
\(1 - (1 - sin^2(x)) = 1 - 1 + sin^2(x)\)
Finally, we get the simplified expression:
\((1 - cos x)(1 + cos x) = sin^2(x)\)
To simplify the expression \(\sf\:(1-\cos x)(1+\cos x)\\\), follow these steps:
Step 1: Apply the distributive property.
\(\longrightarrow\sf\:(1-\cos x)(1+\cos x) = 1 \cdot 1 + 1 \cdot \\\)\(\sf\: \cos x -\cos x \cdot 1 - \cos x \cdot \cos x\\\)
Step 2: Simplify the terms.
\(\longrightarrow\sf\:1 + \cos x - \cos x - \cos^2 x\\\)
Step 3: Combine like terms.
\(\longrightarrow\sf\:1 - \cos^2 x\\\)
Step 4: Apply the identity \(\sf\:\cos^2 x = 1 - \sin^2 x\\\).
\(\sf\:1 - (1 - \sin^2 x)\\\)
Step 5: Simplify further.

What is equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

Answers
The central angle of mobile phones section in February be 91°
Given,
The total number of electronic devices sold by a shop in January = 900
According to pie chart
900 implies 360°. Therefore, 900/360 = 2.5
Now lets check the number of devices sold in January:
Desktop = 60° ⇒ 60 × 2.5 = 150
Laptop = 146° ⇒ 146 × 2.5 = 365
Tablet = 84° ⇒ 84 × 2.5 = 210
Mobile = 70° ⇒ 70 × 2.5 = 175
Its given that in February, all other numbers are same except Mobile phones.
40% more mobile phones are sold in February than in January.
So, number of mobile phones sold in February = 175 × (140/100) = 245
Now lets calculate the total number of devices sold in February:
900 - 175 = 725
725 + 245 = 970
970 devices sold in February.
According to pie chart:
970 implies 360 = 970/360 = 2.69
Now lets check the degree in pie chart for each devices,
Desktop = 150 ⇒ 150/2.69 = 55.7°
Laptop = 365 ⇒ 365/2.69 = 135.5°
Tablet = 210 ⇒ 210/2.69 = 78°
Mobile = 245 ⇒ 245/2.69 = 91°

marla earns an annual salary of $28,000 at her new job. She received a 3% salary increase every year. Find Marla’s total earnings over the course of her first five years working at her job.
Answers
ANSWER:
$148,655.8
STEP-BY-STEP EXPLANATION:
Given:
Original salary = $28,000
Increase per year = 3%
The sum of all the earnings would be the sum of the original salary, the salary after 1 year, the salary after 2 years, the salary after 3 years and the salary after 4 years.
The salary in each year is calculated by multiplying the original salary by the increase raised after n years, just like this:
\(\begin{gathered} s_n=28000\cdot(1+3\%)^n_{} \\ s_n=28000\cdot(1+0.03)^n_{} \\ s_n=28000\cdot(1.03)^n_{} \end{gathered}\)Therefore, the total earnings would be as follows:
\(\begin{gathered} t=28000+28000\cdot(1.03)^1+28000\cdot(1.03)^2+28000\cdot(1.03)^3+28000\cdot(1.03)^4 \\ t=28000+28840+29705.2+30596.4+31514.2 \\ t=148655.8 \end{gathered}\)Therefore, the earnings in the first 5 years of MARla is $148,655.8

How do I determine whether a graph is a function?
Answers
Here's a more detailed explanation: To determine if a graph is a function, you can use the vertical line test. The vertical line test states that if you can draw a vertical line that intersects the graph in more than one place, then the graph is not a function.
Determining whether a graph represents a function is an important concept in mathematics, especially in algebra and calculus. A function is a set of ordered pairs where each input is associated with exactly one output.
So, if you take a ruler or a straight edge and place it vertically on the graph, and it intersects the graph in two or more points, then the graph is not a function. This is because if two points in the graph have the same x-value, they must have different y-values, since functions can only have one output for each input.
On the other hand, if you place a vertical line anywhere on the graph and it intersects the graph in only one point, then the graph is a function.
It's also important to remember that a function must also pass the horizontal line test, which means that no horizontal line can intersect the graph in more than one place.
