Step-by-step explanation:

Circumcenter of A triangle is the center of a circle passing through the vertices of the given triangle.

So, the distance of Z from the vertices Q, R and S will be the radii of the circle.

Therefore, ZQ = ZR = ZS

Since, circumcenter of a triangle is defined by the point of intersection of the perpendicular bisectors of the sides of the given triangle.

Therefore, points W, X and Y are the midpoints of sides QR, RS and QS.

Using these facts,

a). QR = 2(WQ)

          = 2(25)

          = 50

b). Apply Pythagoras theorem in ΔRXZ,

    (RZ)² = (RX)² + (ZX)²

    (RZ)² = (40)² + (9)²

     RZ = √1681 = 41

c). XS = [tex]\frac{1}{2}(RS)[/tex]

          = [tex]\frac{1}{2}(80)[/tex]

          = 40

d). Since, ZQ = ZR = ZS

    ZS = 41

e). By applying Pythagoras theorem in ΔRWZ,

   (RZ)² = (WZ)² + (WR)²

   (41)² = (WZ)² + (25)²

   (WZ)² = (41)² - (25)²

    WZ = √1056

   WZ = [tex]4\sqrt{66}[/tex]

          ≈ 32.5

Applying the circumcenter theorem and the Pythagorean Theorem, the following measures are calculated as:

a. QR = 50

b. RZ = 41

c. XS = 40

d. ZS = 41

e. WZ = 32.5

Based on the circumcenter theorem of a triangle, the following holds true given that Z is the circumcenter of triangle QRS:

Given:

a. Find QR:

QR = 2 × WQ = 2 × 25

QR = 50

b. Find RZ in right ΔXRZ:

XZ = 9 (given)

XR = 1/2(RS) = 1/2(80) = 40

RZ = √(XZ² + XR²)

RZ = √(9² + 40²)

RZ = 41

c. Find XS:

XS = 1/2(RS) = 1/2(80)

XS = 40

d. Find RZ:

RZ = ZS = QZ = 41 (equidistant)

ZS = 41

e. Find WZ in right ΔWRZ:

WR = WQ = 25

WR = 25

RZ = 41

WZ = √(RZ² - WR²)

WZ = √(41² - 25²)

WZ = 32.5

The mistake is on the second line of her work.

She wrote -2x + 4 when it should have been -2x -4 because she multiplied -2 by 2 the 4 would be negative: -2 x 2 = -4

Then adding 4 to the 7, x would be 11

Answer: She’s wrong because on the second line, she should’ve put -2x-4 instead of -2x+4 . X equals 11 because if you add 4 to 7 that’s what you’ll get ,

The value of the simplified expression is 4.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

18 - 6 (2 + 4 - 1 + 2) ÷ 3

Apply the PEMDAS rule.

P = Parenthesis

E = exponents

M = Multiplication

D = Division

A = addition

S = Subtraction

Step 1:

18 - 6 (8 - 1) ÷ 3 ( remove the parentheses )

18 - 6 x 7 ÷ 3

Step 2:

18 - 42 ÷ 3 ( Multiplication )

Step 3:

18 - 42/3 (Division)

18 - 14

Step 4:

18 - 14 ( Subtraction )

Answer: The lines through the pairs of points are perpendicular.

Step-by-step explanation: The lines when graphed do not have the same slope so they can not be parallel. However, when graphed the points (-3, 5) and (-1, 0) goes through the midpoint of the points (-3,1) and (2,3) meaning that the above points are perpendicular! Hope this makes sense and helps.

Step-by-step explanation:

Given:

Anna’s cell phone plan charges her $30 per month plus a $150 one-time activation fee.

Evelyn’s cell phone plan charges her $20 per month, plus a $450 one-time activation fee.

To find:

The number of months after which the costs for the girls’ cell phone plans the same.

Solution:

Let x be the number of months.

Total cost = Fixed cost + Variable cost

According to the question, cost equation for Anna’s cell phone is

[tex]y=150+30x[/tex]           ...(i)

Cost equation for Evelyn's cell phone is

[tex]y=450+20x[/tex]         ...(ii)

Equate (i) and (ii) to find the time after which the costs for the girls’ cell phone plans the same.

[tex]150+30x=450+20x[/tex]

[tex]30x-20x=450-150[/tex]

[tex]10x=300[/tex]

Divide both sides by 10.

[tex]x=\dfrac{300}{10}[/tex]

[tex]x=30[/tex]

Therefore, the costs for the girls’ cell phone plans the same after 10 months.

Step-by-step explanation:

We cannot write [tex]\sqrt{103}[/tex] as a ratio of integers, so that's why it's irrational.

Note that [tex]\sqrt{103} \approx 10.1488915650922[/tex]

The decimal digits go on forever without any pattern. If the digits repeated themselves, then we would have a rational number.

A quick way to tell if it is rational or not, without using a calculator, is to note that 103 is not a perfect square. The list of perfect squares are:

1,4,9,16,25,36,49,64,81,100,121,...

we see that 100 is the closest perfect square, but 103 is not in that list. Each perfect square is of the form x^2, where x is some positive whole number.

Answer:

Yes this is irrational like the guy above me said you cannot write it as a ratio, of integer since rational numbers are:

A rational number is any integer,

fraction,

terminating decimal,

or repeating decimal.

So its Not Rational
