[tex]Given,\ To\ find\ for\ x,[/tex]

[tex]Let\ c\ be\ the\ centre\ of[/tex]

[tex]Circle,\ where[/tex][tex]AD=22.4\ (Diameter)[/tex]

[tex]AC=\frac{22.4}{2}=11.2\ (radius)[/tex]

[tex]AB=8.8[/tex]

[tex]In\ \Delta\ ABC, Right\ angled\ at[/tex]

[tex]B.\ USing Pythagoras\ theovem[/tex]

[tex](AB)^2+(BC)^2=(AC)^2[/tex]

[tex](8.8)^2+(BC)^2=(11,2)^2[/tex]

[tex](BC)^2=125.44-77.44=48[/tex]

[tex]BC=\sqrt{48}=6.92[/tex]

[tex]E_c=x+y\ \ \ \ \(Where\ Fc\ is\ also\ radius\ of\ arcle[/tex]

[tex]\therefore\ \ \ \ \11.2=x+6.92[/tex]

[tex]x=11.2-6.92=4.28[/tex]

Answer:

[tex]m\angle QPO + (2x+16)^\circ = 180^\circ[/tex]

Step-by-step explanation:

In a cyclic quadrilateral, opposite angles add up to 180 degrees. Therefore, our answer would be the third answer, [tex]m\angle QPO + (2x+16)^\circ = 180^\circ[/tex], where QPO and QRO are opposite of each other.

An expression has numbers, variables, and mathematical operations. The factors of the expression x³-4x²+7x-28 are (x²+7)(x-4).

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The factors of the expression x³-4x²+7x-28 can be written as,

[tex]x^3-4x^2+7x-28\\[/tex]

Take x² as the common factor from the first two terms while 7 as the common factor from the last two terms.

[tex]x^3-4x^2+7x-28\\\\=x^2(x-4)+7(x-4)\\\\=(x^2+7)(x-4)[/tex]

Hence, the factors of the expression x³-4x²+7x-28 are (x²+7)(x-4).

The other roots of the given polynomial equation are 2 and -2.

Given polynomial equation is:

[tex]x^{6} -16x^{2} =4x^{4} -64[/tex].....(1)

A polynomial is the sum of monomials of the form axⁿ where n is a whole number.

Rewriting the (1) as:

[tex]x^{6} -4x^{4} -16x^{2} +64=0[/tex]

[tex]x^{4} (x^{2} -4)-16(x^{2} -4)=0[/tex]

[tex](x^{2} -4)(x^{4} -16)=0[/tex]

[tex]x^{2} -4=0[/tex]

[tex]x^{2} =4[/tex]

[tex]x=2[/tex]

[tex]x=-2[/tex]

So, the other roots are 2 and -2.

Hence, the other roots of the given polynomial equation are 2 and -2.

Answer:

  a = 80°

Step-by-step explanation:

In order to solve this figure, we need to find a useful relationship between the various angles. We can use the straight angle at the upper left vertex of the equilateral triangle.

__

The sum of angles there is ...

  a + 60° +(a/2) = 180°

  3/2a = 120° . . . . . . . . . . subtract 60°, collect terms

  a = 80° . . . . . . . . multiply by 2/3

Additional comment

All triangles are isosceles, because they all have 2 (or more) sides the same length. That means the base angles are half the supplement of the a.pex angle. Of course, adjacent vertices of a rhombus have supplementary angles.

Answer:

f(x) = -5x - 2

Step-by-step explanation:

Plug in the first set of values into each possible equation. Whichever equation yields the correct ouputs (y-values) for ALL input (x-values) is the correct answer. For the function f(x) = -5x - 2,  f(-2) = 8, f(-1) = 3 and so on... So f(x) = -5x - 2 is the correct answer!

The Answer is C: [tex]y > x, y < 4[/tex]

Step-by-step explanation:

By looking at the graph the shaded area is the inequalities that you need to find.

[tex]y=4[/tex] is the lines on the y-axis. Below the y-axis is shaded [tex]y < 4[/tex].

From the [tex]y=x[/tex] is a linear line. Above the linear line is [tex]y > x[/tex]

2x+4(2x+7)=3(2x+4)

2x+8x+28=6x+12

10x+28=6x+12

4x+28=12

4x=-16

x=-4

Answer:

4x²+20x+16=0

Step-by-step explanation:

First we can expand the right side:

[tex](2x+4)(2x+7) = 4x^{2} +8x+14x+28[/tex]

Simplify:

[tex]4x^{2} +26x+28[/tex]

Now we can expand the left side:

[tex]3(2x+4) = 6x+12[/tex]

Now we equate both of them to each other:

[tex]4x^{2} +26x+28= 6x+12[/tex]

To make this into a quadratic form we can subtract 6x+12 from both sides:

[tex]4x^{2} +26x+28 - (6x+12) = 6x+12- (6x+12)[/tex]

Simplify

[tex]4x^{2} +20x+16 = 0[/tex]

This is the equation in most simplified version.
