Answer:

Let x = the price of one shirt

Since he bought 3 shirts, he will pay three times the amount. Also, there is a discount. With the discount, the total cost is $63.

We can set up an equation to represent this scenario. Assuming we have a 30% discount as David said

3(x - 0.3x) = 63

Just so you understand, (x - 0.30x) is the sales price for one shirt. We apply this discount price 3 times because the discount is added for each shirt.

Solve for x from this equation to get the price for one shirt.

3(0.70x) = 63

2.1x = 63

x = 30

The value of x and y are 40° and 40° respectively

A circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident.

These are the few theorems of circle geometry

1. The angle at the centre is twice the angle at the circumference.

2. The angle in a semicircle is a right angle.

Angles in the same segment are equal.

3. Opposite angles in a cyclic quadrilateral sum to 180°

4. The angle between the chord and the tangent is equal to the angle in the alternate segment.

from triangle AOB,

angle 0 = 60° (opposite angles)

x = 180-( 80+60)

x = 180-140

x = 40°

x= y ( angle in the same segment are equal)

y = 40°

therefore the value of x and y are 40°

The answer to the question "What is (fog)(x)?" is:
(fog)(x) = x

The first step in solving this problem is to find the composition of f and g, or (fog)(x). This is done by substituting the expression for g(x) into the expression for f(x):
(fog)(x) = f(g(x)) = f(1/11x) = 11(1/11x) = x
Similarly, we can find the composition of g and f, or (gof)(x), by substituting the expression for f(x) into the expression for g(x):
(gof)(x) = g(f(x)) = g(11x) = 1/11(11x) = x
Now, we can determine whether (fog)(x) = (gof)(x) by comparing the two expressions. Since both (fog)(x) and (gof)(x) are equal to x, we can conclude that (fog)(x) = (gof)(x).
Therefore, the answer to the question "What is (fog)(x)?" is:
(fog)(x) = x

It takes approximately0.082 seconds for the eraser to hit the student in the head.

The equation that models the flight of the eraser is h(t)=-16t^(2)+35t+6. We need to find the time it takes for the eraser to hit the student's head, which is 3 feet off the ground. This means that we need to solve the equation h(t)=3 for t.

First, we will set h(t) equal to 3 and rearrange the equation:

-16t^(2)+35t+6=3

Next, we will subtract 3 from both sides of the equation and simplify:
-16t^(2)+35t+3=0

Now, we will use the quadratic formula to solve for t:
t= (-35±√(35^(2)-4(-16)(3)))/(2(-16))

Simplifying further, we get:
t= (-35±√(1417))/(-32)

Using a calculator, we can find the approximate values of t:
t≈0.082 or t≈2.27

Since we are looking for the time it takes for the eraser to hit the student's head, we will choose the larger value of t, which is 0.082.

Therefore, it takes approximately0.082 seconds for the eraser to hit the student in the head.

The solutions in radian units are:
Ω = 0.928, 2.213, 4.070, 5.355
The solutions should be entered as a comma-separated list:
Ω = 0.928, 2.213, 4.070, 5.355

The equation cos(Ω) = -cos(2Ω) can be solved by using the double angle formula for cosine. The double angle formula for cosine is cos(2Ω) = 1 - 2sin^2(Ω).

Substituting the double angle formula into the original equation gives:
cos(Ω) = - (1 - 2sin^2(Ω))

Rearranging the equation gives:
2sin^2(Ω) = 1 + cos(Ω)

Squaring both sides of the equation gives:
4sin^4(Ω) - 4sin^2(Ω) - cos^2(Ω) = 0

Using the identity cos^2(Ω) = 1 - sin^2(Ω) gives:
4sin^4(Ω) - 4sin^2(Ω) - (1 - sin^2(Ω)) = 0

Simplifying the equation gives:
4sin^4(Ω) - 3sin^2(Ω) - 1 = 0

Using the quadratic formula gives:
sin^2(Ω) = (3 ± √(9 + 16))/8

Solving for sin(Ω) gives:
sin(Ω) = ±√(7/8)

Taking the inverse sine of both sides gives:
Ω = sin^-1(±√(7/8))

After comparing the image and the figure, we found that the direction and angle of rotation are 180° counterclockwise rotation.

A transformation known as a rotation involves turning the figure either clockwise or counterclockwise. The centre of rotation is the fixed location where the rotation occurs. The term "angle of rotation" refers to the amount of rotation. A figure can be rotated 90 degrees, or a quarter turn, in either a clockwise or counterclockwise direction.

You have rotated the figure 180 degrees when you have spun it exactly halfway. The figurine may be rotated 360° by turning it all the way around. A counterclockwise turn has a positive magnitude because a clockwise rotation indicates a negative magnitude. Rotational symmetry exists in every regular polygon. When an object is rotated around its centre, it retains its original appearance. The object is then referred regarded as having rotational symmetry.

Let's write the coordinates of the original figure,

A = (1, -5)

B = (6, -2)

C = (6, -5)

D = (1, -8)

Now, if we rotate it 90 degrees counterclockwise, the coordinates are:

A' = ( 5, 1)

B' = (2, 6)

C' = (5, 6)

D' = (8, 1)

Now if we rotate it again 90 degrees counterclockwise, the coordinates are:

A'' = ( -1, 5)

B'' = (-6, 2)

C'' = (-6, 5)

D'' = (-1, 8)

Now from the figure, let's write the coordinates.

A' = ( -1, 5)

B' =  (-6, 2)

C' = (-6, 5)

D' =  (-1, 8)

This is the same as the coordinates of the second 90 degrees counterclockwise rotation.

Since we did two 90 degrees rotations, we can say we did a total of 180° counterclockwise rotation.

Therefore after comparing the image and the figure, we found that the direction and angle of rotation are 180° counterclockwise rotation.

Step-by-step explanation:

since 16 is a positive number and the 7 is negative, it would basically be 16 - 7.

a) The transition probability matrix of the Markov chain is:

| 0.2 0.7 0.1 0 |

| 0.1 0.4 0.5 0 |

| 0.333 0 0.333 0.333 |

| 1-p  0       0    p   |

b) The proportion of old trees that will be in old state after 12 years is 0.613.

c) If a forest starts with all young trees and p = 0.8, the proportion of the trees in the forest that will be old after 18 years is 0.413.

a) The transition probability matrix of the Markov chain is given by:

| Young | Medium | Large | Old |
|-------|--------|-------|-----|
| 0.2   | 0.7    | 0.1   | 0   |
| 0.1   | 0.4    | 0.5   | 0   |
| 0.333 | 0      | 0.333 | 0.333|
| 1-p   | 0      | 0     | p   |

b) The proportion of old trees that will be in old state after 12 years can be found by multiplying the transition probability matrix by itself twice (since each period is 6 years and we want to find the proportion after 12 years).

The resulting matrix will give the probabilities of each state after 12 years. The proportion of old trees that will be in old state after 12 years is given by the element in the fourth row and fourth column of the resulting matrix.

| Young | Medium | Large | Old |

| 0.407 | 0.14   | 0.14  | 0.613|

The proportion of old trees that will be in old state after 12 years is 0.613.

c) If the forest starts with all young trees, the initial state vector is [1, 0, 0, 0]. To find the proportion of the trees in the forest that will be old after 18 years, we need to multiply the initial state vector by the transition probability matrix three times (since each period is 6 years and we want to find the proportion after 18 years).

The resulting vector will give the probabilities of each state after 18 years. The proportion of the trees in the forest that will be old after 18 years is given by the fourth element of the resulting vector.

Let 4,8,12,20,24 be the sequence's first five terms.

Let me define the terms explicit formula and recursive formula.

The generic formula to find any term in a series is known as the explicit formula.

Also, if we know the (n-1)th term of the series, we can use the recursive formula to find the nth term.

Thus, the sequence's explicit formula is,

Y equals 4 n, where n is any positive integer.

And this is the recursive formula.

Y = 4 (n-1), and we can find the nth term by using the (n-1)th term.

Initial term = 4 = 4 1

Term two = 8 = 4 2

Term three =12=43

Fourteenth term = 16 = 4 4

.....................

...........................

.................................

(n-1) th term =4 × (n-1)

nth term =4 × n

The universal and recursive formula is obtained by applying the straightforward technique of examining the first, second, and direction of the next term.

You stated that you did not desire a simpler sequence.

Think about the sequence's first five terms: 0, 3,8, 15, and 24.

Well stated formula =n2 + 2 n

Recursive equation: (n-1)

Third term =8=4+4=2²+2×2

Fourth term =15=9+6=3²+2×3

Fifth term =24=16 +8=4²+2×4

In the explicit formula, n is a whole number and n²+2n.

Therefore, the formula explicitly = n² + 2 n, where n is a full number and the first 5 numbers of the sequence would be 4, 8, 12, 20, and 24.

Step-by-step explanation:

I'm sure the question is asking to solve for ∠BDC, but we'll solve for all of the angles.

We should note that we have a Given Exterior Angle.

An Exterior Angle is an angle that is formed by extended lines.

An exterior angle is equal to the combined sum of the two nonadjacent, and interior angles.

Using what we learned, ∠BCD and ∠CDB will equal ∠DBE°.

Let's turn this problem into an equation.

60° + ∠BDC = 120°
Subtract 60 from both sides.

∠BDC = 60°.

We can also identify that ∠CBD is a linear pair with ∠DBE.

A Linear Pair is 2 adjacent angles that add up to 180°. Linear Pairs are straight lines with one line intersecting in between.

Meaning that ∠CBD + ∠DBE = 180°.

∠CBD + 120° = 180°.

∠CBD = 60°.

We can identify that this triangle is an Equilateral Triangle. An Equilateral  Triangles is a triangle that has all congruent sides and angles.

Our final answers are;

∠BDC = 60°.

∠CBD = 60°.

Julia will finish the upcoming 6.2-mile race first among her friends, beating the second-place finisher by 5 minutes and 42 seconds.  

Distance is the measure of how far apart two objects or points are. It is expressed in terms of length, area, volume, or time. It is a numerical measurement of how much space is between two points or objects. Distance can also be used to measure the length of a journey, or to measure the speed of an object moving over a certain period of time.

To calculate this, we can look at the table and compare the times of the last race each of them ran. Julia ran a 5-mile race in 32 minutes and 45 seconds, her first friend ran a 4-mile race in 28 minutes and 20 seconds, and her second friend ran a 4-mile race in 29 minutes and 15 seconds.

To calculate the time difference between Julia and the second-place finisher, we can compare the total time they would run the 6.2-mile race. Julia would run the 6.2 miles in 40 minutes and 45 seconds (32 minutes and 45 seconds for the 5-mile race plus 8 minutes for the additional 1.2 miles) and the second-place finisher would run the 6.2 miles in 41 minutes and 35 seconds (29 minutes and 15 seconds for the 4-mile race plus 12 minutes and 20 seconds for the additional 2.2 miles). The difference between the two times is 5 minutes and 42 seconds, so Julia would finish first and beat the second-place finisher by 5 minutes and 42 seconds.

To find out how many stamps Sierra and her brother each collected, we need to set up an equation and solve for the unknown variable.

Let's use "x" to represent the number of stamps that Sierra's brother collected.
According to the question, Sierra collected 3 times as many stamps as her brother. So, we can represent Sierra's number of stamps as 3x.
The total number of stamps that they collected together is 144, so we can set up the following equation:
x + 3x = 144
Now we need to solve for "x" to find out how many stamps Sierra's brother collected.
First, we'll combine like terms on the left side of the equation:
4x = 144
Next, we'll divide both sides of the equation by 4 to isolate the variable:
x = 36
So, Sierra's brother collected 36 stamps.

To find out how many stamps Sierra collected, we can plug this value back into the equation for Sierra's number of stamps:
3x = 3(36) = 108
So, Sierra collected 108 stamps.

if we move the sides closer and ever closer to each other, to the extent that one is right on top of the other, what is the length of the red side?  Well, assuming the two smaller sides are one pancaked on top of the other, the red side will be as long as 2.7 - 1.9 = 0.8.  However, the sides can't be on top of each other, because if that's so, we have a flat-line, and thus we wouldn't have a triangle.  So whatever the third side may be, it must be greater than 0.8.

Now, if we move the sides away from each other, farther and farther to the extent that one is parallel to the other, then the third side will just be as long as 1.9 + 2.7 = 4.6.  However, we can't do that, because if that were to happen, we again will have a flat-line and not a triangle.  So whatever the third side may be, it must be less than 4.6, it can't be 4.6.
