On solving the provided question, we can say that coordinates of the point in the unit circle  S = ( cos [tex]3\pi /2[/tex] , sin [tex]3\pi /2[/tex] ) => S= ( 0 , -1 )

Every point in the plane that is a certain distance away from a certain point forms a circle (center). It is, thus, a curve formed by points moving in the plane at a fixed distance from a point. At every angle, it is also rotationally symmetric about the center. A circle is a closed two-dimensional object where every pair of points in the plane are equally spaced out from the "center." A line that goes through the circle creates a specular symmetry line. At every angle, it is also rotationally symmetric about the center.

S = (0, -1 )

Step-by-step explanation:

Given the system of equation, \left \{ {{x+6y=28} \atop {2x-3y=-19}} \right.{

2x−3y=−19

x+6y=28

, solve by elimination.

\left \{ {{-2(x+6y=28)} \atop {2x-3y=-19}} \right.{

2x−3y=−19

−2(x+6y=28)

, multiply the top equation by -2.

We get, \left \{ {{-2x-12y=-56} \atop {2x-3y=-19}} \right.{

2x−3y=−19

−2x−12y=−56

+ {{-2x-12y=-56} \atop {2x-3y=-19}} \right. , add the equations together.

We get, -15y=75−15y=75 , we just eliminated the variable, x, we can now solve this equation for y.

-15y=-75 = > y=\frac{-75}{-15}−15y=−75=>y=

−15

−75

, y=\frac{75}{15} = > y=5y=

15

75

=>y=5

We just found the value y, which is y=5. Now we can take this value and plug it into y for either of the two original equations and solve for x. I will take the top equation...

x+6y=28 = > x+6(5)=28 = > x+30=28x+6y=28=>x+6(5)=28=>x+30=28 , subtract the value, 30, from both sides. We get, x=-2x=−2 .

We found the value x, x=-2.

Thus the solution to the given system of equations is (-2,5).

The product of (2x-3y)(2x+3y) is 4x^2-9y^2

Product= (2x-3y)(2x+3y)

Let the product of (2x-3y)(2x+3y) be P

P=2x(2x+3y)-3y(2x+3y)

P= 2x(2x)+2x(3y)-3y(2x)-3y(3y) {using distributive property of multiplication}

This property states that  multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together. The multiplication of (a-b)(a+b) is equal to a^2 - b^2. This result is used as an identity.

P= 4x^2 +6xy - 6xy -9y^2

solving 6xy-6xy=0

P= 4x^2 - 9y^2

4x^2-9y^2 is the product of (2x-3y)(2x+3y).

Answer:

Step-by-step explanation:

The linear equation f(x) is  4x - 10 and the quadratic equation f(k) is -5/2k^2 + 4k - 1 for the two given points.

The linear equation can be found using the slope-intercept form (y = mx + b), where m is the slope of the line and b is the y-intercept. To find the slope (m) we can use the two points given:

m = (y2 - y1) / (x2 - x1) = (18 - 2) / (7 - 3) = 16/4 = 4

The y-intercept (b) can be found using one of the points and the slope:

b = y - mx = 2 - 4(3) = -10

So the linear equation in standard form is:

f(x) = 4x - 10

For the quadratic equation, we know that it's in the form of y = ax^2 + bx + c. We have 2 points, so we have 2 equations with 2 unknowns. We can use this information to solve for a, b and c.

Let's (3,2) point 1 and (7,18) point 2.

f(k) = ak^2 + bk + c....(1)

point 1: f(3) = 2 = 9a + 3b + c...(2)

point 2: f(7) = 18 = 49a + 7b + c...(3)

Now we have 2 equations and 3 unknowns.

using theirs first equation and substitute it in the second and third equation

18 = 49a + 7b + c

2 = 9a + 3b + c

c = 2 - 9a - 3b

18 = 49a + 7b + (2 - 9a - 3b)

18 = 49a + 7b + 2 - 9a - 3b

18 = 40a + 4b + 2

16 = 40a + 4b

now this equation is used to solve for a and b

b = (16 - 40a) / 4

so a,b and c are

a = -5/2

b = 4

c = -1

so the quadratic equation in standard form is:

f(k) = -5/2k^2 + 4k - 1

4x - 10 is the linear equation f(x)  and -5/2k^2 + 4k - 1 is the quadratic equation f(k) for the two given points.

No, the sides of a right triangle do not include 8, 15, and 17. The sides of a right triangle must follow the Pythagorean theorem, so the sum of the squares of the two shorter sides must equal the square of the longest side. 8² + 15² does not equal 1

8² + 15² = 64 + 225 = 289

17² = 289

Therefore, 8, 15, and 17 are not the sides of a right triangle.

The Pythagorean theorem is an important mathematical concept used to determine if three numbers form the sides of a right triangle. This theorem states that the sum of the squares of the two shorter sides must equal the square of the longest side. In the case of 8, 15, and 17, 8² + 15² does not equal 17², so it is not a right triangle. To test this, we can calculate 8² + 15² = 289, and then 17² = 289. Since the two values are not equal, we can conclude that 8, 15, and 17 are not the sides of a right triangle.

The result of (x-3)(4x+2) using FOIL method is 4x^2 -6x +2x -6.

The FOIL method is a technique used to multiply two binomials. It stands for "First, Outer, Inner, Last" and follows these steps:

First: Multiply the first term of the first binomial by the first term of the second binomial

Outer: Multiply the first term of the first binomial by the second term of the second binomial

Inner: Multiply the second term of the first binomial by the first term of the second binomial

Last: Multiply the second term of the first binomial by the second term of the second binomial

Applying FOIL method to (x-3)(4x+2) we get:

First: 4x * x = 4x^2

Outer: 4x * -3 = -12x

Inner: -3 * 4x = -12x

Last: -3 * 2 = -6

So the result of (x-3)(4x+2) is 4x^2 -12x -12x -6 = 4x^2 -24x -6.

Answer:

2027 = $122.25

2016 = $48

Step-by-step explanation:

Find 1% of 75

75 / 100 = 0.75

multiply by 9

0.75 * 9 = 6.75

So that's $6.75 each year

Now, lets find our answers for 7 years.

6.75 * 7 = $47.25

75 + 47.25 = $122.25

The stock will be $122.25 in 2027

Now for 2016.

$6.75 * 4 = $27

$75 - $27 = $48

The question is incomplete, as the required figure is not attached to the question.

From the question, we can deduce that the telescope is a composite figure made from a cone and a cylinder.

To get the volume of the materials used, you have to calculate the volume of the cone and that of the cylinder.

The sum of these volumes, is your answer.

Assume the following dimensions:

Cone

[tex]r = 5\\[/tex] --- radius

[tex]h = 7[/tex] --- height

Cylinder

[tex]r = 5\\[/tex] --- radius

[tex]h = 20[/tex] --- height

The volume of the cone is:

[tex]Volume = \frac{1}{3} \pi r^2h[/tex]

[tex]V_1= \frac{1}{3} \pi *5^2*7[/tex]

[tex]V_1= \frac{1}{3} \pi *25*7[/tex]

[tex]V_1= \frac{175}{3} \pi[/tex]

The volume of the cylinder is:

[tex]Volume = \pi r^2h[/tex]

[tex]V_2 = \pi * 5^2 * 20[/tex]

[tex]V_2 = \pi * 25* 20[/tex]

[tex]V_2 = 500\pi[/tex]

The total is:

[tex]Volume = V_1 + V_2[/tex]

[tex]Volume = \frac{175\pi}{3} + 500\pi[/tex]

Take LCM

[tex]Volume = \frac{175\pi+1500\pi}{3}[/tex]

[tex]Volume = \frac{1675\pi}{3}[/tex]

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given few inequalities and some operations are performed on them

For first inequality:

=> 4 < 7

Multiply both sides by 3, then by 2, then by 4, then by 9

=> 4 *3 * 2 * 4 * 9 < 7  *3 * 2 * 4 * 9

=> 864 < 1512

there is no change in the inequality sign and it is still true.

For the second inequality:

=>11 > -2

Add 3 to both sides, then add 3, then add (-4)

=> 11 +3 + 3 + (-4) > -2 + 3+3 + (-4)

=> 13 > 0

there is no change in the inequality sign and it is still true.

For the third inequality:

=> -2 ≤ -2

Subtract 6 from both sides, then 8, and then 2

=> -2 -6 -8 -2 ≤  -2 -6 -8 -2

=>  -18 ≤ -18

there is no change in the inequality sign and it is still true.

For the fourth inequality:

=> -4 < 8

Divide both sides by -4

=> -4 / -4 < 8 / -4

Since, after dividing or multiplying on both sides by a negative sign, inequality changes its sign

=> 1 > -2

Divide both sides by -2

=> -1/2 < 1

there are two times a change in the inequality sign and it is still true.
