What is the value of 2x 3y 36 when Y 6?.

Answer:

the answer is (-3)

Step-by-step explanation:

its to make it work

These are the vertex, focus, directrix, and focal width

Vertex: (0, 0), Focus: (0, 7), Directrix: y = -7, Focal width: 28

The vertex, focus, directrix, and focal width of the parabola described by the equation x^2 = 28y are:

Vertex: (0, 0)

Focus: (0, 7)

Directrix: y = -7

Focal width: 28

The vertex of a parabola is the midpoint of the directrix and the focus, which in this case is (0, 0). The focus is the point on the parabolic curve that is closest to the directrix, which in this case is (0, 7).

The directrix is the line along which the distance between the parabolic curve and its focus is minimized, which in this case is y = -7. The focal width is the distance between the focus and the directrix, which in this case is 28.

we can conclude that the probability for the first apple than the peach fruit is 10/39.

What is probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Here, we have

Given that there are 8 apples and 5 peaches in a basket.

Total Fruits = 13

For the first event, the probability of getting an apple is,

P(A) = 8/13

Now, Total Fruits = 12

For the second event, the probability of getting peach is,

P(B) = 5/12

The probability for both events is given below.

P = P(A)×P(B)

P = 8/13 ×  5/12

P = 40/156 = 10/39

Hence we can conclude that the probability for the first apple than the peach fruit is 10/39.

The amount of money that the farmer will make after the deduction of percentage of service fees would be = $783.75

A contract earning is defined as the amount of money an individual or company earns for a period of time which only lasts till the end of the contract.

FROM the question,

1 acre /year = 0.11 metric tons

50 acre/year = 0.11 × 50

In addition, the 45-45-90 triangle is an isosceles triangle, which indicates that each of its legs is the same length.

In a triangle, the trigonometric ratio Tan Theta is the same as opposite or adjacent.

A 45-45-90 triangle has side lengths that are 1: 1: .

As a result, tan45 has a value of 1.

(a)

the y- intercept is the point on the y- axis where the line crosses.

the line crosses at (0, 6 ) , then y- intercept = 6

(b)

the gradient m ( slope) of the line is calculated using the gradient formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 0) and (x₂, y₂ ) = (0, 6) ← 2 points on the line

m = [tex]\frac{6-0}{0-(-3)}[/tex] = [tex]\frac{6}{0+3}[/tex] = [tex]\frac{6}{3}[/tex] = 2

From the adjacent image we can identify the points of the graph.

From the points we can easily find y-intercept and gradient.

How can we identify the points.

Line where cut the x-axis and y-axis. Take that location as point.

For writing point observe the distance of x-axis and y-axis

Let say point A=(0,6) and point B=(-3,0)

For find y-intercept we must know gradient first

Gradient formula for two points m=[tex]\frac{y_{2} -y_{1 }}{x_{2} -x_{1 }}[/tex]

Submit Point A and Point B    m=[tex]\frac{0 -6}{-3 -0\\}[/tex]

Therefore, Gradient of slope m=2

To find y-intercept, we must solve lin equation

m = gradient and b=y-intercept

Submit m in line equation y=2x+b

Submit any one point in the line equation

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 = 13

To find the solution of equation 2x+3y=13, first we solve equation for x and then for any real value of y we find value of x.

We solve this equation for x,

Consider 2x + 3y = 13

2x + 3y - 3y = 13 - 3y            .........(subtract 3y from each side of equation)

2x/2 = (13 - 3y)/2                   .........(divide each side by 2)

x = (13 - 3y)/2

for any real value of y we can find value of x.

This means, an equation 2x + 3y = 13 has infintely many solutions.

The graph of 2x + 3y = 13 is shown below.

What is the solution of 2x + 3y =13?.

The angle 360 degree is called as complete angle.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles.

A form of angle that measures 360° is known as a full angle. When two lines meet at a point, an angle is created, and the angle is the width of the space created.

The angle generated in this case is referred to be the complete angle if, after one complete revolution, the final ray corresponds with the incident or initial ray. A round angle and a complete angle are the alternate names. The angle, which corresponds to the center of a circle, is 2 radians, or 360 degrees. A complete angle is made up of four right angles or two straight angles. The amount of rotation makes the angle different from a zero angle.

An inductive proof requires two cases. The first, or base case, establishes the proposition that n = 0 without requiring any prior knowledge of other situations. The second example, the induction step, demonstrates that if the assertion is true for any particular case where n = k, then it must also be true for the subsequent case when n = k + 1. These two actions prove that the statement is true for all n = 1 natural numbers. The base case establishes the truth of the statement for all natural numbers n N, but it does not always start with n = 0. Instead, it frequently starts with n = 1, and it may also start with any fixed natural number n = N.

Sum is an aggregation of the numbers, quantities etc. It is write as 4 + 4 = 8 ( plus symbol (+ ) represent the sum). Similarly, ∑ (sigma) also represents the sum of numbers.

Addition is an important topic in Mathematics. When we add two or more numbers, the result is defined as the SUM. The added numbers are called addends. The sum of two or more numbers make a new number say total. A plus symbol (+) is used when we add the numbers. Summation (or) sum formula is the sum of consecutive terms of a sequence. To write the sum of more terms, say n terms, of a sequence {an} , we use the summation notation instead of writing the whole sum manually. That is summation symbol which represent the sum is ∑ (sigma). For example, Sum of two numbers say 6 and 7 is equals to 6 + 7 = 13. But in case of "n" numbers the sum is determined as following way. Consider the first n even numbers, i.e., 2,4,6,....,n and we have to calculate the sum of it. As we see the above sequence is in AP with first term, a = 2 and common difference, d= 2. Then the sum formula in AP is S = n/2[ 2a + (n -1)d ]

=> S = n/2 [ 4 + (n-1)2 ]

=> S = n/2 [ 4 + 2n - 2 ]

=> S = n(n+1) or ∑n( n+1,) ; n = 1,2,.......

The coordinates of the midpoint of PQ is (5/8, 1/8)

i. To find the slope of the line l1, you can rearrange the equation 4x - 3y + 5 = 0 to the standard form of y = mx+ b, where m is the slope and b is the y-intercept.

4x - 3y + 5 = 0

3y = -4x + 5

y = (-4/3)x + (5/3)

So the slope of the line l1 is m = -4/3.

ii. To find an equation of the line l2, which passes through the point (1, 2) and is perpendicular to the line l1, you can use the slope-intercept form of a line y = mx + b, where m is the slope and b is the y-intercept. Since line l2 is perpendicular to line l1, the slope of l2 is the negative reciprocal of the slope of l1.

m = -1/(-4/3) = 3/4

We can substitute point (1, 2) into the equation

2 = 3/4 * 1 + b

b = 2 - 3/4

So the equation of the line l2 is y = 3/4 x + (2 - 3/4) = 3/4 x + 1/4

iii. To find the coordinates of the point where line l1 crosses the x-axis, we can set y to 0 and solve for x.

y = (-4/3)x + (5/3)

0 = (-4/3)x + (5/3)

x = 5/4

The point where line l1 crosses the x-axis is (5/4, 0)

Similarly, to find the point where line l2 crosses the y-axis, we can set x to 0 and solve for y.

y = 3/4 x + 1/4

y = 3/4 * 0 + 1/4

y = 1/4

The point where line l2 crosses the y-axis is (0, 1/4)

The midpoint of two points can be found by taking the average of the x and y coordinates.

Midpoint of P and Q = ( (5/4 + 0) / 2, (0 + 1/4) / 2) = (5/8, 1/8)

So the coordinate of the midpoint of PQ is (5/8, 1/8).
