The equation of parabola is [tex]y=1/4x^{2}+x/2-4\\\\[/tex].

A symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side. The path of a projectile under the influence of gravity follows a curve of this shape. A plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line.

Given:

The equation of parabola in vertex form is

[tex]y=a(x-h)^{2} +k[/tex]

Being vertex here

h=-2

k=-5

According to given question we have

∴

Equation of parabola in vertex form is

[tex]y=a(x+2)^{2} -5[/tex]

. The parabola passes through point  (4,4)  So the point (4,4)  will satisfy the equation .

[tex]4=a(4+2)^{2} -5\\\\4=a*36-5\\\\9=a*36\\\\a=9/36\\\\a=1/4[/tex]

Hence the equation of parabola is

[tex]y=1/4(x+2)^{2} -5\\\\y=1/4(x^{2} +4+2x)-5\\\\y=1/4x^{2} +1+x/2-5\\\\y=1/4x^{2}+x/2-4\\\\[/tex]

Step-by-step explanation:

The coordinates of S are (-4,2) .

The sails' center of rotation = Origin (0,0)

Coordinates of S on the top of one of the sails, = (2,4)

The action or process of rotating on or as if on an axis or center.

The center of rotation is a point about which a plane figure rotates. This point does not move during the rotation.

It is given that sails have rotated 270° clockwise.

So, When we rotate a figure of 270 degree clockwise, each point of the given figure has to be changed from (x, y) to (-y, x) and graph the rotated figure.

So, the point  turn (2, 4) into (-4, 2).

Thus, the coordinates of S are (-4,2).

Answer:

∠ EBF = 16°

Step-by-step explanation:

note that EB is the angle bisector of ∠ ABF , then

∠ ABE = ∠ EBF = 2x and

∠ ABF = ∠ ABE + ∠ EBF , that is

7b - 24 = 2b + 2b

7b - 24 = 4b ( subtract 4b from both sides )

3b - 24 = 0 ( add 24 to both sides )

3b = 24 ( divide both sides by 3 )

b = 8

Then

∠ EBF = 2x = 2(8) = 16°

The measure of the angle 2 is 122°.

Given that angles 1 and 2 form a linear pair,

angle 1 + angle 2 = 180 degrees         —— (1)

We've also been notified that angle 2 is 6 times the size of angle 1.

That is to say: angle 2 = (2×angle 1) + 6      ———- (2)

Putting the angle 2 value in (1) from (2)

180 = angle 1 + 2×angle 1 + 6

3×angle 1 = 174

1st angle = 58 degrees  ———-(3)

(1) and (3) come from:

angle 2 + 58 = 180

2nd angle = 122 degrees

As a result, angle 2 has a measure of 122 degrees.

The population mean of the data is 6.

The population has n = 16 scores.

The sum of all of the scores is equal to 96.

Therefore, the population mean can be found as follows:

The population mean is the mean or average of all values in the given population.

The population mean is represented mathematically as follows:

population mean = sum of terms / number of terms

Therefore,

sum of terms = 96

number of terms = 16

The solution of the system of linear equations behind the geometric system is (x, z) = (29, 13). The measures of the angles RIG and ZIM are 59° and 140°, respectively.

In this problem we find a geometric system generated by lines GZ, AM and IR, in which two variables are shown (x, z) and whose values can be found by applying the concepts of complementary and supplementary angles.

A group of angles are complementary if the sum of their measures equals 90°, and supplementary if that sum equals 180°. This system can be represented by the following system of linear equations:

(3 · x - 56) + 90 + (4 · z + 7) = 180       (1)

(4 · z + 7) + (x + 2) = 90                        (2)

By (1):

(3 · x - 56) + (4 · z + 7) = 90

3 · x + 4 · z - 49 = 90

3 · x + 4 · z = 139                                  (1b)

By (2):

x + 4 · z = 81                                         (2b)

The solution of the system of linear equations behind the geometric system is (x, z) = (29, 13).

Then, the measures of the angles RIG and ZIM are, respectively:

m ∠ RIG = 4 · z + 7

m ∠ RIG = 4 · 13 + 7

m ∠ RIG = 59°

m ∠ ZIM = 360° - (3 · x - 56) - 90° - (4 · z + 7) + (x + 2)

m ∠ ZIM = 360 - 3 · 29 - 56 - 90 - 4 · 13 + 7 + 29 + 2

m ∠ ZIM = 140°

The measures of the angles RIG and ZIM are 59° and 140°, respectively.

We are given an expression:

(4 y + 1) × 0 = 0

We need to tell which property is this.

The property that is used is called the property of zero. In this, it states that whenever a number is multiplied by 0, the answer or the result will always be zero.

For example: 3 × 0 = 0, 4 × 0 = 0, M × 0 = 0 or P × 0 = 0.

It does not matter whether a constant or a variable is multiplied with it, the result of the multiplication will always be zero.
