Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given that Cassandra is hanging crystal stars from the gym ceiling using string for the homecoming dance

She wants the ends of the strings where the stars will be attached to be 7 feet from the floor.

BD is perpendicular to AC.

∠BDA+∠2+∠3=180

∠2+∠3=90 degrees.

∠1=∠3 (the equivalent substitution)

ΔABD=ΔBCD

AD/BD=BD/DC

(Similar triangles have sides that are proportional)

AD.DC=BD²

PC⊥AC

∠ACP=90 degrees.

∠ACM+∠MAC+∠∠CAM=180

∠ACM=∠APC

Find the relative maximum and minimum values of f(x,y) = x3/3 + 2xy + y2 - 3x + 1. 3

Answers

The critical point (1, -1) represents a relative minimum of f(x, y) with a value of -1/3 and (1, -1) is the only extremum or relative maximum of the function.

To find the relative maximum and minimum values of the function f(x, y) = (\(x^3\))/3 + 2xy +\(y^2\) - 3x + 1, we need to analyze its critical points and classify them using the second partial derivative test.

To find the critical points, we need to compute the partial derivatives of f with respect to x and y and set them equal to zero:

∂f/∂x = \(x^2\) + 2y - 3 = 0

∂f/∂y = 2x + 2y = 0

Solving these equations simultaneously, we find x = 1 and y = -1.

Thus, the critical point is (1, -1).

Next, we need to compute the second partial derivatives and evaluate them at the critical point:

∂²f/∂x² = 2

∂²f/∂y² = 2

∂²f/∂x∂y = 2

Now, we can use the second partial derivative test to classify the critical point.

The discriminant D = (∂²f/∂x²) × (∂²f/∂y²) - \(\left(\frac{{\partial^2 f}}{{\partial x \partial y}}\right)^2\) = (2)(2) - \((2)^2\) = 0.

Since D = 0, the test is inconclusive.

To determine the nature of the critical point, we can examine the function near the critical point.

Evaluating f at the critical point (1, -1), we find f(1, -1) = \((1^3)\)/3 + 2(1)(-1) + \((-1)^2\) - 3(1) + 1 = -1/3.

Hence, the critical point (1, -1) represents a relative minimum of f(x, y) with a value of -1/3.

There are no other critical points to consider, so we can conclude that (1, -1) is the only extremum of the function.

Find the sum of the series. [infinity] Σn = 0 7(−1)^n ^(2n +1). 3^(2n +1) (2n + 1)!

Answers

The given series is a complex alternating series. By applying the ratio test, we can show that the series converges. However, it does not have a closed form expression, and therefore we cannot obtain an exact value for the sum of the series.

The given series can be written in sigma notation as:

∑n=0 ∞ 7\((-1)^n(\)2n +1) \(3^(2n +1)\) (2n + 1)!

To test for convergence, we can apply the ratio test, which states that if the limit of the absolute value of the ratio of consecutive terms is less than 1, then the series converges absolutely. Applying the ratio test to this series, we get:

lim|(7*\((-1)^(n+1)\) * 3\(^(2n+3)\) * (2n+3)!)/((2n+3)(2n+2)(3^(2n+1))*(2n+1)!)| = 9/4 < 1

Answers

You can say about getting the outcome of precisely 500 tails you should not expect exactly 500 tails in 1000 tosses, but the proportion of tails should approach 0.5 as the number of tosses increases. The correct answer is option B.

You should not expect exactly 500 tails in 1000 tosses, but the proportion of tails should approach 0.5 as the number of tosses increases. The probability of getting a head or a tail while flipping a fair coin is 0.5 or 1/2, respectively. If a fair coin is tossed 1000 times, the probability of getting a head or a tail is 0.5.

Hence, you should expect exactly 500 tails in 1000 tosses.

However, the number of tails tossed is a random quantity, and there is no guarantee that half of the tosses will result in tails. Getting 500 tails is just as likely as getting any other number of tails in 1000 tosses.

Answers

The function \(y = xe^{(2x)} + Ce^z\) is the general solution to the differential equation \(y' = 2y + e^{(2x)}\). A particular solution satisfying y(0) = a is\(y = xe^{(2x)} + ae^z\).

To show that\(y = xe^{(2x)} + Ce^z\) is the general solution of the differential equation \(y' = 2y + e^{(2x)}\), we need to substitute y into the differential equation and verify that it satisfies the equation.

First, let's find y' by taking the derivative of y with respect to x:

\(y' = d/dx (xe^{(2x)}) + d/dx (Ce^z)\)

Using the product rule, we have:

\(y' = e^{(2x)} + 2xe^{(2x)} + C * d/dx (e^z)\)

Since the derivative of \(e^z\) with respect to x is zero, we have:

\(y' = e^{(2x)} + 2xe^{(2x)}\)

Now, substitute y and y' into the differential equation:

\(e^{(2x)} + 2xe^{(2x)} = 2(xe^{(2x)} + Ce^z) + e^{(2x)}\)

Simplifying, we find that the left side is equal to the right side, verifying that y is a solution to the differential equation.

To find a particular solution satisfying the initial condition y(0) = a, we substitute x = 0 into y:

\(y(0) = 0e^{(2*0)} + Ce^z = 0 + Ce^z = a\)

This implies that \(Ce^z = a\), and we can solve for C:

\(C = a/e^z\)

Therefore, a particular solution satisfying the initial condition is\(y = xe^{(2x)} + (a/e^z)e^z = xe^{(2x)} + ae^z.\)

In summary, \(y = xe^{(2x)} + Ce^z\) is the general solution, and a particular solution satisfying y(0) = a is \(y = xe^{(2x)} + ae^z\).

The simplified Boolean functions expressed in the sum of minterms are: option 3-F(A, B, C, D) = BD + CD + ABC

What is Boolean function?

A Boolean function is a mathematical function that operates on one or more Boolean variables and returns a Boolean value as its output. Boolean variables can only have two possible values: true (1) or false (0).

To simplify the given Boolean functions, we can use Karnaugh maps, also known as K-maps. K-maps provide a graphical representation of the truth table and help identify simplification patterns.

For the function F(A, B, C, D), we construct a 4-variable K-map with minterms Σ(0, 6, 8, 13, 14). We place 1s in the corresponding cells for these minterms. By observing the patterns in the K-map, we can group adjacent 1s to form larger groups. The resulting simplified expression is BD + CD + ABC.

For the function d(A, B, C, D), we construct another 4-variable K-map with minterms Σ(2, 4, 10) along with the don't care conditions. By grouping adjacent 1s, we obtain the simplified expression BD + CD.

The simplified expressions are derived from the K-maps using the rules of Boolean algebra and the objective of minimizing the number of terms and literals.

An item is regularly priced at $60. It is on sale for 40% off the regular price. What is the sale price? ​

Answers

Answer: The sale price is $36.

Step-by-step explanation:

40% ÷ 100 = 0.4

0.4 × $60 = $24

$60 - $24 = $36

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

If there is an off of 40% on an item that cost $60.

The regular price of the item is $48.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

105 = 10/100 = 1/10

Example:

50% of 40 is 20.

50/100 x 40 = 20

25% of 100 is 25.

25/100 x 100 = 25.

We have,

Regular price = $60

Off = 40%

Sale price:

= 60 - (40% of 60)

= 60 - (40/100 x 60)

= 60 - (2/5 x 60)

= 60 - (2 x 12)

= 60 - 24

= $48

Since, Alice ate 5 cookies and 2 carrots for a total of 590 calories; bob ate 3 cookies and 4 carrots for a total of 410 calories. Therefore, In a cookie there are 110 calories.

A calorie is a unit of energy that food and drink provide. we can usually find out how many calories are listed in foods, and wearables like the best fitness trackers let you monitor how many calories you're burning in different activities. Certain foods, such as processed foods, tend to be high in calories. Other foods, such as fresh fruits and vegetables, tend to be low in calories. there is not. Calories are needed to give you enough energy to move, keep warm, grow, work, think, and play. Our circulation and digestion also need to work well with the energy we get from calories.

Let x = calories in cookies.

     y = calories in carrots.

Now, according to the question:

     5x + 2y = 590                   --------------------------------------- (1)

     3x + 4y = 410                    -------------------------------------- (2)

Multiplying equation(1) by 3 and equation(2) by 5:

         15x + 6y = 1770                       ---------------------------(3)

         15x + 20y = 2050                   ---------------------------(4)

Solving we get:

    y = 280/14

or, y = 20 units.

Putting the value of y = 20 in equation (2)

    3x + 4y = 410

⇒  3x + 4 × 20 = 410

⇒ 3x = 410 - 80
