What is the domain of the relation?


A)

{-4,- 2 1, 4}

B)

{-2, 1, 4}

C)

{-2, 1, 4, 4}

D)

(-4,-2), (-2,1), (1,4), (4,4)

Answer:

center: (0,0)

radius: 4 units

Step-by-step explanation:

the circle goes through points (0,4), (0,-4), (4,0), and -4,0).

if you notice, all four points are 4 away from the origin, (0,0). this means that there center is (0,0).

if you start at one of the points and go to the origin, it will be 4 units. that will be your radius

Answer:

True

Step-by-step explanation:

Dilations preserve angle measure, betweenness of points and collinearity. It does not preserve distance. Simply, dilations always produce similar figures

Answer:

0.02623 rounds to 0.03

Step-by-step explanation:

ones. tenths hundredths thousands

we look at the thousandths place when rounding to the hundredths

the thousands place is 6 (which is 5 or greater) so we will round the hundreds place up 1

0.02623 rounds to 0.03

Answer:

Jack can form four rectangular prisms with 20 unit cubes.

Step-by-step explanation:

Number of unit cubes Jack has = 20

Factors of 20 = 1, 2, 4, 5, 10, 20

The possible dimensions of a rectangular prism that can be formed by these unit cubes may be,

1 × 1 × 20 (One cube at the base)

1 × 2 × 10 (2 cubes at the base)

1 × 4 × 5 (4 cubes at base in a single row)

2 × 2 × 5 (4 cubes at the base with 2 cubes in length and 2 cubes in width)

Therefore, Jack can form four rectangular prisms with 20 unit cubes.

Answer:

Step-by-step explanation:

A secant is a straight line from a point outside a given circle that passes through two points on its circumference.

From the given diagram, EM and EQ are secants.

Thus,

<PEW ≅ <WEP    (common angles)

<EMP ≅ <EQW (secant-chord theorem)

<WMP ≅ <PQM (inscribed angles of arc WP)

Therefore,

[tex]\frac{EW}{WM}[/tex] = [tex]\frac{EP}{PQ}[/tex]   (corresponding sides of a triangle)

This implies that,

EW*PQ = EP*WM

Therefore,

MP*EW = WQ*EP  (properties of a similar triangle)

Step-by-step explanation:

Split it up.

3 rectangles.

You have two congruent ones, whose area is 2 * 4 = 8 and their total is 16

Then you have another one whose area is 6 * 2 = 12

16 + 12 = 28

1/2*7/8=7/16

Answer:

7/16

The required fraction of 1/2 of 7/8 is given as 7/16.

Fraction is defined as the number of compositions that constitutes the Whole.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
1/2 of 7/8 = 1/2 × 7/8
               = 7 / 16

Thus, the required fraction of 1/2 of 7/8 is given as 7/16.

Answer:

The y-intercept is 3.

Step-by-step explanation:

Step 1: Find the slope of the line.

m =  rise/run = y2 - y1/ x2 - x1

m= 9-(-1)/-3-2

m=10/-5 = -2

Slope-intercept form equation is y = mx + b

Step 2: Plug in slope to slope-intercept equation and solve for b (y-intercept)

y = -2x + b

We can use the point (2, -1)

Plug it in.

-1 = -4 + b

Solve.

b = 3

COS(225°)= -.707

SIN(225°)= -.707

Answer:

cos(225)= 0.3673193677

sin (225)= -0.930094878

Step-by-step explanation:

Answer:

25^2=625

24^2= 576

7^2= 49

as 625 = 576+49 so 7,24,25 form a Pythagorean triplet

Answer:

18a) The height of tree is 6.34ft.

Diagram We would scale a right side triangle showing side; 6.34ft x base 13.59ft x 15cm slope.

b) 11.54 degree

Step-by-step explanation:

18a) sin(25) = 0.4226182617 is what you multiply to check the height.

15 x 0.4226182617 = 6.339273926   = 6.34ft.

Using the measurements of pythagoras you can scale each measurement above.  6.34 = (x0.5) = 3.17cm to draw the trees height.

15ft wire = scale the diagram draw  1cm = 2ft So that 7.5cm =  = 15ft

Draw a right angle triangle and before creating the slope use protractor or guess 25 degree at bottom of slope and label it.

This will make a 7.5cm slope and label it 15ft.

We also measure out the base which on scale cm per foot is 13.59 x 0.5 = 6.80cm and label it 13.59ft.

We find the base measurement by finding the square of each 15 and 6.34

c^2 - a^2 = b^2

a= 6.34 x 6.34 = 40.1863939089 = √40.19

c = 15 x 15 =  √225

c-b = √225 - √40.19 =  √184.81

side = b  

b^2 = √184.81= 13.5944841756 = 13.59ft

18 b)  To find an angle x  with given measurements 4ft base and 20ft slope we  

use sin( base/slope) = (run/rise)

So that 4/20 = 0.2  

Then plug in for sin -1  0.2 = 11.54 degree = (calc ..11.53695903)

Notes;

If 4ft base was not given and the height of wall was given we would do the same using base as run and slant as run run/rise  but we would substitute sin-1 and after division run/rise we would plug in the decimal to cos-1 (decimal).

To find f(3) we just need to plug in 3 wherever we see an n

f(3) = f(3 - 2) + f(3 - 1)

f(3) = f(1) + f(2)

Since f(1) and f(2) are given, we can plug in the respective values

f(3) = f(1) + f(2) → f(3) = 1 + 2 = 3

Step-by-step explanation:

The value of x using the concept of similar triangles is; x = 41/36

Two triangles are said to be similar if their corresponding angles are congruent and their corresponding sides are proportional. So you can find the dimensions of a triangle using another triangle. If ABC and XYZ are two similar triangles, you can find the associated angles and side lengths using the formulas below.

∠A = ∠X, ∠B = ∠Y, and ∠C = ∠Z

AB/XY = BC/YZ = AC/XZ

Thus, our Triangle is solved as;

4/9 = 24/(12x - 3)

24(4/9) = 12x - 3

32/3 = 12x - 3

32 = 36x - 9

36x = 41

x = 41/36
