The rule of reflection for the triangle is Ry ( x , y ) → ( -x , y )

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Given data ,

Let the triangle be represented as ΔMLN

Now , the coordinates of the triangle are

The coordinate of M = M ( -5 , 4 )

The coordinate of L = L ( -6 , 2 )

The coordinate of N = N ( -3 , 2 )

when the triangle is reflected across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse.

The reflection of point (x, y) across the y-axis is (-x, y).

So , the coordinate of M' = M' ( 5 , 4 )

The coordinate of L' = L' ( 6 , 2 )

The coordinate of N' = N' ( 3 , 2 )

Hence , the rule of reflection is Ry ( x , y ) → ( -x , y )

Answer:

A 1:3

Step-by-step explanation:

Point P(-1, -12/5) partitions the line segment AB in the ratio of 2:1, which is calculated using the section formula in coordinate geometry.

To determine the ratio at which point P partitions AB, we can use the concept of section formula in coordinate geometry. The section formula states that if a point P(x, y) divides the line segment AB in the ratio m:n, then its coordinates are given by:

[tex]\[ x = \frac{mx_2 + nx_1}{m + n} \quad \text{and} \quad y = \frac{my_2 + ny_1}{m + n} \][/tex]

Substituting the given coordinates of A(-3, -4), B(2, 0), and P(-1, -12/5), we can form two equations with the unknowns m and n. Solving for m and n will give us the required ratio.

[tex]\[ -1 = \frac{m \cdot 2 + n \cdot (-3)}{m + n} \text{ and } (-\frac{12}{5}) = \frac{m \cdot 0 + n \cdot (-4)}{m + n} \][/tex]

Solving the equations, we find m = 2 and n = 1, meaning P divides AB in the ratio of 2:1, which is option B.

Answer:

Volume of larger ball = 220,781.3 cubic centimeters

Step-by-step explanation:

Let's use ratios to solve for the diameter of the larger ball first (let the diameter of larger ball be L)

[tex]\frac{LargerBall}{SmallerBall}=\frac{15}{11}=\frac{L}{55}\\11*L=15*55\\11*L=825\\L=\frac{825}{11}=75[/tex]

So, the diameter of the larger ball is 75 cm. We know radius is half of diameter, so radius of larger ball is (1/2)(75) = 37.5 cm

Ball is in the shape of a sphere, which has a formula for volume as:

[tex]V=\frac{4}{3}\pi r^3[/tex]

where V is the volume and r is the radius

now we simply plug in 37.5 into r and use 3.14 as π:

[tex]V=\frac{4}{3}\pi r^3\\V=\frac{4}{3}(3.14)(37.5)^3\\V=220,781.3[/tex]

Answer:

In 1981, the Australian humpback whale population was 350

Po = Initial population = 350

rate of increase = 14% annually

P(t) = Po*(1.14)^t

P(t) = 350*(1.14)^t

Where

t = number of years that have passed since 1981

Year 2000

2000 - 1981 = 19 years

P(19) = 350*(1.14)^19

P(19) = 350*12.055

P(19) = 4219.49

P(19) ≈ 4219

Year 2018

2018 - 1981 = 37 years

P(37) = 350*(1.14)^37

P(37) = 350*127.4909

P(37) = 44621.84

P(37) ≈ 44622

There would be about  44622  humpback whales in the year 2018

Final answer:

To predict the Australian humpback whale population, an exponential growth model is used with equation P(t) = 350  [tex]imes (1 + 0.14)^t.[/tex] By substituting t with the number of years since 1981, we can estimate the population for any given year.

Explanation:

To write the equation for a function you could use to predict the number of humpback whales, we can use an exponential growth model because the population increases by a constant percentage rate each year. The general form of an exponential growth model is [tex]P(t) = P0 imes (1 + r)t,[/tex]where P(t) is the population at time t, P0 is the initial population, r is the growth rate, and t is the number of years since the initial time.

Given that the initial population in 1981 was 350 whales and the growth rate is 14% or 0.14, and taking t to be the number of years since 1981, the function to predict the number of whales in year t is:

[tex]P(t) = 350 imes (1 + 0.14)t[/tex]

For the number of whales in the year 2000, we substitute t with 19 (since 2000-1981=19), and for the year 2018 it would be 37 (since 2018-1981=37).

To predict the number of humpback whales in the year 2018, we use the function with t=37:

[tex]P(37) = 350 imes (1 + 0.14)37[/tex]

Calculating this, the result is rounded to the nearest whole number giving us the approximate whale population in 2018.

x=15

I know its kind of confusing, it took me a while to get geometry down too.

But I hope this helps :)

Answer:

x = 15

Step-by-step explanation:

Since the triangles are similar, we can say that the ratio between the respective sides of the first triangle and the 2nd is constant.

Basically, VW / ST = VU/SR = WU/TR = k, where k is a positive real number

Solving for k is simple:

k = VU/SR = 42/21 = 2

So we found out that the 1st triangle is the 2nd triangle but scaled up 2 times.

We use this to find x.

ST * 2 = VW

2x = 30

x = 15

If it was asking for one can you would put 42.41 because it is (pi)(1.5)^2(6)

But then you times it by 6 cans and you get 254.47inches cubed

The total volume of juice in a six-pack, with each can being 6 inches tall and having a diameter of 3 inches, is 254.34 cubic inches. This is calculated using the volume formula for a cylinder.

The question asks for the total volume of juice in a six-pack of cans, where each can is 6 inches tall and has a diameter of 3 inches. To find the volume of one can, we use the formula for the volume of a cylinder: V = πr^2h, where V is volume, r is radius, and h is height. First, we find the radius of the can by dividing the diameter by 2, which gives us 1.5 inches. The volume of one can is therefore calculated as V = π(1.5)^2(6), which simplifies to V = π(2.25)(6) = 42.39 cubic inches. To find the total volume for a six-pack, we multiply this volume by 6: 42.39 in^3  × 6 = 254.34 in^3. Therefore, the total volume of juice in the six-pack is 254.34 cubic inches.

an = 3 * (3)^ (n-1)  or

an = 3^n

Step-by-step explanation:

To find the common ratio, take the second term and divide by the first term

9/3 = 3

To verify take the third term and divide by the second

27/9 =3

Since this is a geometric sequence, it is of the form

an = a1*r^(n-1)  where a1 is the first term and r is the common ration

an = 3 * (3)^ (n-1)

Since the first term is the same as the term inside the parentheses, we can combine

an = 3^1 * 3 ^ (n-1)

   = 3^ (1+n-1)

  = 3^ (n)

An algebraic equation is a mathematical statement that contains two or more algebraic expressions that are set equal to each other. The algebraic expressions can contain variables, constants, and operators.

We have:

3(17x – 6.5) = 108

We can solve for the value of x as follow:

3(17x – 6.5) = 108

17x(3) - 6.5(3) = 108

51x - 19.5 = 108

51x = 108 + 19.5

51x = 127.5

x = 127.5/51

x = 2.5

Therefore, x equal to 2.5 in this equation

Saving account: A = 500(1 + 0.023t)

CD account: A = 500(1 + 0.018/12)^(12t)

Future value of saving account is $730

Future value of CD account is $716.47

She should choose the saving account

Step-by-step explanation:

* Lets revise the rules of simple and compound interest

- Simple Interest Equation (Principal + Interest)

 A = P(1 + rt)

- Where:

• A = Total amount (principal + interest)  future amount

• P = Principal Amount

• I = Interest Amount

• r = Rate of Interest per year in decimal; r = R/100

• t = Time Period involved  

- Compound interest can be calculated using the formula

 A = P (1 + r/n)^(nt)

Where:

• A = the future value of the investment, including interest

• P = the principal investment amount (the initial amount)

• r = the annual interest rate (decimal)

• n = the number of times that interest is compounded per unit t

• t = the time the money is invested for

* Now lets solve the problem

- Saving account:

# P = $500

# r = 2.3/100 = 0.023

# t = t

∴ A = 500(1 + 0.023t) ⇒ (1)

- CD account:

# P = $500

# r = 1.8/100 = 0.018

# n = 12

# t = t

∴ A = 500(1 + 0.018/12)^(12t) ⇒ (2)

* In case t = 20 years

- In equation (1)

# A = 500(1 + 0.023 × 20) = $730

- In equation (2)

# A = 500(1 + 0.018/12)^(12 × 20) = $716.47

Step-by-step explanation:

[tex]a^2.\frac{a^{3}+a^2b }{5a}.\frac{25}{3b+3a}[/tex]

We need to solve the above equation.

We take a^2 common from a^3+a^2b

and we take 3 common from 3b+3a

Solving,

[tex]a^2\:\frac{a^2\left(a+b\right)\:}{5a}\frac{25}{3\left(b+a\right)}[/tex]

Since a+b = b+a we can cancel them with each other.

[tex]=a^2\:\frac{a^2}{5a}\frac{25}{3}\\=a^2\:\frac{a^2}{a}\frac{5}{3}\\=a^2\:a\:\frac{5}{3}\\=\frac{5a^3}{3}[/tex]

So, The simplified result is: [tex]\frac{5a^3}{3}[/tex]

The simplified expression is (5(a + b)) / (3a(b + 1)).

To simplify the given expression, we'll perform the indicated operation step by step:

a² * [(a³ + a²b) / 5a] * [25 / (3b + 3a)]

Step 1: Cancel common factors within each fraction:

a² * [(a³ + a²b) / (5a)] * [25 / (3(b + a))]

Step 2: Simplify further:

(a³ + a²b) * [25 / (5a * 3(b + a))]

Step 3: Factor out common terms:

(a²(a + b)) * [25 / (15a(b + a))]

Step 4: Cancel common factors between numerators and denominators:

(a + b) * (25 / (15a(b + a)))

Step 5: Simplify further:

(25(a + b)) / (15a(b + a))

Step 6: Factor out common terms again:

(25(a + b)) / (15a * a(b + 1))

Step 7: Cancel common factors:

(5(a + b)) / (3a(b + 1))

So, the simplified expression is (5(a + b)) / (3a(b + 1)).
