Explanation:

To get the domain, list the x coordinate of each point shown.

The points on that graph are (-1, 1), (0, -2), (1, 3) and (3, 0). We see the x coordinates are: -1, 0, 1 and 3

Therefore, the domain is {-1, 0, 1, 3} which is choice A. The curly braces indicate we have a set of values. The domain is the set of all possible x inputs.

Answer:

(2³)³=512

because, 2³=8 & 8³=512

Answer:

512

Step-by-step explanation:

Ok, let's start by deciphering how powering works:

[tex]a^3 = a \cdot a \cdot a\\a^b * a^c = a^{b+c}\textrm{; because it's "multiply a b times" multiplied by "multiply a c times"}\\(a^b)^c = a^{b\cdot c}\textrm{; because of the above}\\[/tex]

[tex](2^3)^3 = 2^{3\cdot3} = 2^9\\[/tex]

and because of KibiBytes existing, we know that 2^10 = 1024, so 2^9 will be equal to 1024/2=512

Answer:

(8.21, -20.79)

Step-by-step explanation:

Given the simultaneous equation;

[tex]\frac{a}{b} - \frac{b}{2} = 10\\a - b = 29[/tex]

From 2;

a = 29 + b ....3

Substitute 3 into 1;

[tex]\frac{29+b}{b} - \frac{b}{2} = 10\\\frac{2(29+b)-b^2}{2b} = 10\\\frac{58+2b-b^2}{2b} = 10\\58+2b-b^2 = 20b\\b^2-2b-58 = -20b\\b^2-2b+20b -58 = 0\\b^2+18b-58 = 0\\[/tex]

Factorize

b = -18±√18²-4(-58)/2

b = -18±√324+232/2

b = -18±√556/2

b = -18±23.58/2

b = -18-23.58/2 and -18+23.58/2

b = -41.58/2 and 5.58/2

b = -20.79 and 2.79

Since a = 29 + b

when b = -20.79

a = 29 - 20.79

a = 8.21

Hence the solution to the system of equation is (8.21, -20.79)

Answer:

y = -1 and u = 3.333

Step-by-step explanation:

The given equations are :

3u + y = 9 ...(1)

3u-5y = 15 ...(2)

Subtract equation (2) from (1).

3u + y-( 3u-5y)= 9 -15

y+5y = -6

6y = -6

y = -1

Put the value of y in equation (1).

3u + (-1) = 9

3u-1 = 9

3u = 10

u = 10/3

u = 3.333

The attached figure shows the graph for the above equations.

Answer:

the answer is 50, trust me!

Step-by-step explanation:

The measure of AU is 50.

An arc is a part of a curve that is a continuous portion of the circumference of a circle or an ellipse. It is defined by two endpoints and the arc itself, which is the curved section between the endpoints.

Given:

arc QU = 88 and <QUA = 111

So, QDA = 2 <QUA

        = 2 X 111

        = 222

Now, QUA = 360- 222 = 138

and, arc AU = QUA - arc QU

           = 138- 58

           = 50

Hence, the measure of AU is 50.

Answer:

444

Step-by-step explanation:

The radius of a circle is the center point to the end of the circle in any direction.

the diameter of a circle is the full stretch of the circle.

In order to find out the diameter from the radius all you have to do is multiply the radius by 2.

222*2=444.

An isosceles triangle is one with two equal-length sides. The value of x is 58°.

An isosceles triangle is one with two equal-length sides. It is sometimes stated as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter form containing the equilateral triangle as a particular case.

Since the given triangle is an isosceles triangle, therefore, the angle opposite to side 6.25 units will be equal, therefore, the sum of all the angles of the triangle will be,

61° + 61° + x = 180°

x = 58°

Hence, the value of x is 58°.

Answer:

Step-by-step explanation:

Answer:

21

Step-by-step explanation:

Hey There

So remember all of the angles in a triangle add up to equal 180

The exterior angle is equal to the missing interior angle because they are vertical angles

so 180 = 2x + 6 + x + 9 + 129

step 1 combine like terms

6+9+129=144

2x+x=3x

now we have

180=144+3x

step 2 subtract each side by 144

180-144=36

now we have

3x=36

step 3 divide each side by 3

36/3=12

Now we just plug in 12 to x+9

12+9=21

so we can conclude that angle A = 21
