Answer:

  $18.97

Step-by-step explanation:

You want to know Ai Mi's bill if her $16 lunch had 6% tax added, and she tipped 14% on the amount with tax.

Adding tax multiplies the bill by (1 +6%) = 1.06.

Adding the tip on the amount with tax multiplies that amount by (1 +14%) = 1.14.

The total cost of Ai Mi's lunch is ...

  ($16(1.04))(1.14) ≈ $18.97

The total cost with tax and tip was $18.97.

Vector equation: r(t) = <1, -1, 7> + t<6, 7, -6>

Parametric equations:

x(t) = 1 + 6t

y(t) = -1 + 7t

z(t) = 7 - 6t

The vector equation and parametric equations describe the line segment that joins the two points p and q.

The vector equation is given by r(t) = <1, -1, 7> + t<6, 7, -6>

Here, <1, -1, 7> is the vector that represents the point p, and <6, 7, -6> is the direction vector of the line segment.

The variable t is a scalar parameter that describes the position of any point on the line segment.

The parametric equations are x(t) = 1 + 6t, y(t) = -1 + 7t, z(t) = 7 - 6t.

These equations express the coordinates of any point on the line segment in terms of the parameter t. So we can substitute any value of t between 0 to 1 in this equation to get the coordinates of a point on the line segment.

For example, if we substitute t = 0, we get x(0) = 1, y(0) = -1, z(0) = 7

which gives us the coordinates of point p.

Similarly, if we substitute t = 1, we get x(1) = 7, y(1) = 6, z(1) = 1

which gives us the coordinates of point q.

So, the line segment is defined by the set of all points whose coordinates are given by these equations for values of t between 0 and 1.

Answer: 8 shirts for 128 shekels

Step-by-step explanation:

First, we can set up fractions and simplify to find the cost of one shirt.

5shirts/100shekels = 1shirt/20 shekels

8 shirts/128 shekels = 1shirt/16 shekels

Ultimately, whichever cost per shirt is lower is going to be the better buy. Since 16shekels/shirt is less than 20shekels/shirt, you are ultimately buying more shirts for a lower cost. Hope this helps

where M is we can see that those 3 sections add up to make 180.

Therefore 180-96=84 and 84/2=42 so the angles by 84 on both side is 42 since we know that LM and MN is the same we can then determine that the angles in the middle triangle add up to make 180.  By looking at the proofs at the top NO and LM are the same so both the bottom angles in each triangle is 42. So we know that 84 is the addition of both the bottom angles 180 - 84 is 96. We set that equal to 3x. 3x=96 Divide both sides by 3 x is equal to 32.

Step-by-step explanation:

The rate of change of the radius is -9/(2π*99) inches/second.

The volume of a cylinder can be found with the equation V = πr^2h, where V is the volume, r is the radius, h is the height and π is a constant. We know that the volume is constant at 1318 cubic inches and we know that the height of the cylinder is increasing at a constant rate of 9 inches per second.

V = πr^2h

1318 = π * 99^2 * h

Now we can differentiate this equation with respect to time.

dV/dt = 2πr*dr/dt * h + πr^2 * dh/dt

where dV/dt is the rate of change of the volume, dr/dt is the rate of change of the radius and dh/dt is the rate of change of the height.

Now we know that dV/dt = 0, dh/dt = 9 and we know the value of r, we can substitute these values in the above equation and solve for dr/dt

0 = 2π * 99 * dr/dt * h + π * 99^2 * 9

dr/dt = -9/(2π*99) inches/second

The rate of change of the radius is -9/(2π*99) inches/second at the instant when the radius of the cylinder is 99 inches.

Answer: It is greater than 4.

Step-by-step explanation: It is equal to 2 root 5. But if you convert to a decimal you get 4.4721 which is greater than 4.

The formula to find the square root is: y=√a

The probability of getting one defective component per customer is very low, less than 1/14,254. The probability of getting five defective components to a single customer is also low, 1/14,254. And the probability of getting two defective components to two different customers and the rest of the customers getting none is 10/14,254.

(a) The probability that each customer will receive one defective component is the probability that the five defective components will be drawn in a specific order, divided by the total number of ways the 50 components can be drawn. There are 5049484746 ways that the 50 components can be drawn, and 5! (5 factorial) ways that the defective components can be drawn in a specific order. So the probability is (5!)/(5049484746) = 1/14,254.

(b) The probability that one customer will have drawn five defective components is the probability that all five defective components will be drawn in a row, divided by the total number of ways the 50 components can be drawn. There are 5049484746 ways that the 50 components can be drawn, and 5! (5 factorial) ways that the defective components can be drawn in a row. So the probability is (1!)/(5049484746) = 1/14,254,

(c) The probability that two customers will receive two defective components each, two none, and the other one, is the probability that the five defective components will be drawn in a specific order and then divided among the five customers in a specific way, divided by the total number of ways the 50 components can be drawn. The number of ways to divide the defective components among the customers is 5!/(2!2!1!) = 10. There are 5049484746 ways that the 50 components can be drawn, and 5! (5 factorial) ways that the defective components can be drawn in a specific order, so the probability is (105!)/(50494847*46) = 10/14,254.

The greatest number of elements that s can have is 2002, and the set s = {1,2,3,4,5,...,2002}

The property of the set s states that for every element x in s, the arithmetic mean of the set obtained by deleting x from s is an integer.

To understand this property, we can start by considering the case when the set s has only two elements, say x and y. In this case, the arithmetic mean of the set obtained by deleting x from s is y, and the arithmetic mean of the set obtained by deleting y from s is x. As both x and y are integers, this property holds true.

When the set s has three elements, say x, y, and z. The arithmetic mean of the set obtained by deleting x from s is (y+z)/2. as y and z are integers, (y+z) is always even, thus (y+z)/2 is always an integer. The same applies to the arithmetic mean of the set obtained by deleting y and z.

As we can see, this property holds true for any set of distinct positive integers, no matter the number of elements.

Given that 1 belongs to s and that 2002 is the largest element of s, we can use the property of the set to find the greatest number of elements that s can have.

The arithmetic mean of the set obtained by deleting 1 from s is (x+y+z+...+2002)/(n-1) = (x+y+z+...+2002)/n + 1/n. as x, y, z... 2002 are integers, (x+y+z+...+2002) is always an integer, thus (x+y+z+...+2002)/n is always an integer. Then, as 1/n is always an integer, (x+y+z+...+2002)/n + 1/n is always an integer.

Therefore, the greatest number of elements that s can have is 2002, and the set s = {1,2,3,4,5,...,2002}

Answer:

To solve the equation cos (2x) = √2 - cos (2x), we can first isolate the variable on one side of the equation.

cos (2x) = √2 - cos (2x)

add cos(2x) to both sides

2*cos(2x) = √2

divide both sides by 2

cos(2x) = √2/2

Now we can use the identity cos 2x = 2cos^2 x - 1, so

2cos^2 x - 1 = √2/2

Square both sides

4cos^2 x - 2 = 2 - 1

4cos^2 x = 1

Divide both sides by 4

cos^2 x = 1/4

Since cos^2 x = 1/4, then cos x = +/- √(1/4) = +/- 1/2

So x = pi/3 + 2npi or x = 5pi/3 + 2n*pi

To show that var(aX + bY + c) = a^2 var X + b^2 varY + 2ab cov(X, Y), we can start by using the definition of variance, which is var(X) = E[(X - E[X])^2], and the definition of covariance, which is cov(X, Y) = E[(X - E[X])(Y - E[Y])].

Variance is a measure of the spread of a random variable's possible values. It is defined as the expected value of the squared deviation of a random variable from its mean. For a random variable X, the variance is denoted as Var(X) or σ^2(X) and is calculated as:

Var(X) = E[(X - E[X])^2]

Using these definitions, we can write:

var(aX + bY + c) = E[(aX + bY + c - E[aX + bY + c])^2]

Using the properties of expectations and bilinearity, we can simplify this to:

var(aX + bY + c) = E[(a(X - E[X]) + b(Y - E[Y]))^2]

Expanding the square and using bilinearity again, we get:

var(aX + bY + c) = a^2 E[(X - E[X])^2] + b^2 E[(Y - E[Y])^2] + 2ab E[(X - E[X])(Y - E[Y])]

Since the expectations of (X - E[X])^2 and (Y - E[Y])^2 are equal to var(X) and var(Y) respectively, we can substitute these values into the above equation to get:

var(aX + bY + c) = a^2 var X + b^2 varY + 2ab cov(X,Y)

Therefore, we have shown that var(aX + bY + c) = a^2 var X + b^2 varY + 2ab cov(X,Y)

Step-by-step explanation:

At the 20th generation, 400 squares, 400 triangles, and 400 trapezoids are needed.

The pattern for the first through the fifth generations of squares, triangles, and trapezoids is that each generation is made up of the previous generation's shapes, but with each shape having an additional set of smaller shapes attached to each side.

For example, in the first generation, there is only one square. In the second generation, four smaller squares are attached to the sides of the first square. In the third generation, nine smaller squares are attached to the sides of each of the four squares in the second generation, and so on.

The number of shapes needed to create each generation can be found using the formula:

(n^2)

Where n is the generation number.

For example, in the first generation, only 1 square, 1 triangle and 1 trapezoid is needed, in the second generation, 4 of each are needed, in the third generation, 9 of each are needed, and so on.

If this pattern holds for each generation, the number of tiles required at the 20th generation can be found by substituting n = 20 into the formula:

(20^2) = 400

To determine if the generation you are building is similar (by mathematical definition) to the other generations, you would need to check whether the ratio of corresponding sides is the same for each shape in the generation.

When you double the dimensions of a given polygon, the area is multiplied by four. When you triple the dimensions of a given polygon, the area is multiplied by nine.

The pattern for the number of shapes needed to create each generation follows the pattern of a square of n^2. Therefore, the number of tiles required at the 20th generation can be found by substituting n = 20 into the formula, n^2 = 20^2 = 400.
