Write an equation of the graph shown in terms of cosine:
Answer:
Step-by-step explanation:
A squiggly line can refer to a variety of different shapes or patterns. To create an equation using cosine that resembles a squiggly line, you can use a combination of sine and cosine functions with different frequencies and amplitudes. Here's an example equation that produces a squiggly pattern:
y = A * cos(B * x) + C * sin(D * x)
In this equation, A, B, C, and D are constants that you can adjust to modify the shape and characteristics of the squiggly line. By experimenting with different values for these constants, you can create various squiggly patterns. Keep in mind that the specific equation may vary depending on the exact shape and features you have in mind for the squiggly line.

What does it mean to round a number to a particular place?Rounding a number to a particular value reduces the complexity of the number while increasing readability and accessibility.
When you round to a certain point, the exact digits are maintained on the left side of that point but are rounded or somewhat trimmed from the right.
The limit is set at five.
All right-sided values are made zero if the right-side digit to the digit where we must round off is less than or equal to five; otherwise, it is increased by one and the remaining right-side digits are made zero. If the digit to the right of the decimal point is 5, and there are just zeros or no values after it, we round up (raise by 1 as in 347500 to 34800). (Well there are many detailed rules of rounding)
The following can be used to represent the provided expression, "pi plus the square root of forty to the closest hundredth,"
π + √40
= 3.1416 + 6.3245
= 9.4661 ≈ 9.47
Value is therefore 9.47.

using only 32 cents and 20 cent stamps charlie put 3 dollars and 36 cents on a package he sent to his sister he used twice as many 32 cent stamps as 20 cent stamps determine how many of each stamp he used
Using only 32 cents and 20 cent stamps Charlie put 3 dollars and 36 cents on a package he sent to his sister. He used 8- 32 cent stamps and 4-20 cent stamps.
Let x = Number of 20c stamps.
So, 2x = Number of 32c stamps.
20(x) + 32(2x) = 336
20x + 64x = 336
84x = 336
x = 4 (20c stamps)
2x = 8 (32c stamps).
Verify:
4 x 20 = 80 cents
8 x 32 = 256 cents
80+256 = $3.36.
Therefore, Charlie used 4 - 20 cent stamps and 8 - 32 cent stamps to sent the package to his sister.

Make x the subject K(x-a)=t
Answer:
x = t+ka/k
Step-by-step explanation:
First you take letter k and place it after =sign which brings (x-a) = t/k because if you shift any number or letter after the = sign it has to be the opposite sign. for instance if it's positive, it will turn negative after the equal sign and if it is multiplication, it will turn division
Then you open the brackets which makes x-a = t/k
Now you shift "a" after the equal sign which leads to our answer, x= t +ka/k
Answer:
x = \(\frac{t+ka}{k}\)
Step-by-step explanation:
k(x - a) = t ← distribute parenthesis on the left side by k )
kx - ka = t ( add ka to both sides )
kx = t + ka ( divide both sides by k )
x = \(\frac{t+ka}{k}\)

Yolanda has a 1/6 -cup ladle that she uses to pour gravy over potatoes. She uses one full ladle for each serving of potatoes. Yolanda has 6 cups of gravy. How many servings of potatoes can she make?
Answer: For 6 cups of gravy, Yolanda will have 36 servings of potatoes
Step-by-step explanation:
Step 1
Since Yolanda has a 1/6-cup of ladle for one full serving
Then for every serving the 1/6- cup ladle is used and can be expressed as
1 serving =1/6-cup of ladle
Step 2--- Solving
Serving of potatoes for 1 cup is
1 serving =1/6 cup of ladle
?? servings=1 cup of ladle ( cross multiply)
= 1 x 6/1 = 6 servings
Therefore 6 cups of gravy = 6 servings x 6 = 36 servings of potatoes

I need to show work
Therefore , the solution of the given problem of expressions comes out to be x = 1.0730 is roughly the answer to the equation 10*e(³ˣ) = 250.
What does an expression precisely mean?When variables are shifting, estimates should be created that mix joining, disabling, and instead of randomly dividing. They could answer a puzzle collectively, offer some information, and instead software. Formulas, elements, and mathematical operations like addition, subtraction, grouping, and combination are all found in a statement of truth. Words and sentences can both be evaluated and analysed.
Here,
In order to find x in the equation 10*e(3x) = 250, we can start by dividing both parts by 10 to isolate the exponential term:
=> e³ˣ = 25
The exponential can then be removed by taking the natural logarithm (ln) of both sides:
=> ln(e(³ˣ) = ln(25)
We can simplify the left half by using the fact that ln(ey) = y:
=> 3x = ln(25)
By multiplying both parts by 3, we can finally find the value of x:
=>x = (1/3) * ln(25)
We can use a computer to determine that the value of ln(25) is roughly 3.2189. Therefore:
=> x ≈ (1/3) * 3.2189
=> x ≈ 1.0730
So x = 1.0730 is roughly the answer to the equation 10*e(³ˣ) = 250.

The table shows the multiplication of two linear expressions. Select the correct reason for each step.
Reason 1:
Reason 2:
Reason 3:
here are the answer choices for the 3 reasons
(A)associative property of multiplication
(B)commutative property of multiplication
(C)istributive property
(D) simplify
Answer:
1. (C) Distributive property | 2. (A) Associative property | 3. (D) Simplify
Step-by-step explanation:
Here's my attempt:
Reason 1:
The first reason is (C) distributive property of multiplication because you're taking the previous step and spreading it out (distributing it). Here's an example of the distributive property of multiplication:
3(4+7) = 3*4+3*7=12+21=33
This will be the same as solving 3(4+7) using PEMDAS
In this step, you're spreading out the problem the same way as the example shown is doing.
Reason 2:
The second reason is (A) the associative property of multiplication. The associative property of multiplication says that changing the grouping of the numbers in a multiplication problem doesn't change the product.
Here's an example:
(6*7)*8 = 6*(7*8)
This way, the step groups together two pairs of factors to solve the last step without changing the product.
Reason 3:
The final reason is (D) Simplify because the step doesn't use the commutative property of multiplication. Why not? Because the commutative property of multiplication states that changing the order of factors in a multiplication problem doesn't change the product (note that this is different than the associative property of multiplication). Instead, the last step just simplifies the problem.
Hopefully, you read through my explanation, and it helped. Have a good day :D

а 3. Determine a real root for f(x) = x- 6x + 11x - 6.1: a. Using the fixed-point method (three iterations, x = 3.5). b. Using the Newton-Raphson method (three iterations, x = 3.5). C. Using the secant method (three iterations, X-1 = 2.5 and x = 3.5).
The real root of the given equation using the fixed-point method is \(3.427\), the Newton-Raphson method is \(3.427\) and secant method is \(3.427\) respectively.
\(\textbf{Given equation:}\)
The given equation is \(f(x) = x^3 - 6x^2 + 11x - 6.1\).
\(\textbf{a. Fixed Point method:}\)
Using the formula \(X_n = g(X_{n-1})\), where \(g(x)\) is a suitable function of \(x\) chosen so that \(f(x) = 0\) can be written as \(x = g(x)\). We will choose \(g(x) = (6x^2 - 11x + 6.1)^{\frac{1}{3}}\) as the value of \(g(x)\).
Thus, we have:
\(X_0 = 3.5\),
\(X_1 = (6(3.5)^2 - 11(3.5) + 6.1)^{\frac{1}{3}} \approx 3.476\),
\(X_2 = (6(3.476)^2 - 11(3.476) + 6.1)^{\frac{1}{3}} \approx 3.449\),
\(X_3 = (6(3.449)^2 - 11(3.449) + 6.1)^{\frac{1}{3}} \approx 3.427\).
\(\textbf{b. Newton Raphson method:}\)
Using the formula \(X_{n+1} = X_n - \frac{f(X_n)}{f'(X_n)}\), where \(f'(X_n)\) is the derivative of \(f(x)\) at \(X_n\). We choose \(f'(x) = 3x^2 - 12x + 11\) as the value of \(f'(x)\).
Thus, we have:
\(X_0 = 3.5\),
\(X_1 = X_0 - \frac{f(X_0)}{f'(X_0)} = 3.5 - \frac{f(3.5)}{f'(3.5)} \approx 3.430\),
\(X_2 = X_1 - \frac{f(X_1)}{f'(X_1)} = 3.430 - \frac{f(3.430)}{f'(3.430)} \approx 3.427\),
\(X_3 = X_2 - \frac{f(X_2)}{f'(X_2)} = 3.427 - \frac{f(3.427)}{f'(3.427)} \approx 3.427\).
\(\textbf{c. Secant method:}\)
Using the formula \(X_{n+1} = X_n - \frac{f(X_n)(X_n - X_{n-1})}{f(X_n) - f(X_{n-1})}\), where \(X_n\) and \(X_{n-1}\) are two initial approximations. We choose \(X_n = 3.5\) and \(X_{n-1} = 2.5\) as the initial values, as they are close to the root of the equation \(f(x) = 0\).
Thus, we have:
\(X_0 = 2.5\),
\(X_1 = 3.5\),
\(X_2 = X_1 - \frac{f(X_1)(X_1 - X_0)}{f(X_1) - f(X_0)} = 3.5 - \frac{f(3.5)(3.5 - 2.5)}{f(3.5) - f(2.5)} \approx 3.434\),
\(X_3 = X_2 - \frac{f(X_2)(X_2 - X_1)}{f(X_2) - f(X_1)} = 3.434 - \frac{f(3.434)(3.434 - 3.5)}{f(3.434) - f(3.5)} \approx 3.427\).
Thus, the real root of the given equation using the fixed-point method is \(3.427\), the Newton-Raphson method is \(3.427\) and secant method is \(3.427\) respectively.

How do I find the current price of a stock when the rate is not constant? Please give a formula step by step answer I'm so confused
Answer:
There is no affirmative formula, but this is the basics
Step-by-step explanation:
DDM Formula=
Stock value = Dividend per share / (Required Rate of Return – Dividend Growth Rate)
Rate of Return = (Dividend Payment / Stock Price) + Dividend Growth Rate.
The P/E Ratio. The price-to-earnings ratio or P/E ratio is a popular metric for valuing stocks that works even when they have no dividends. Regardless of dividends, a company with high earnings and a low price will have a low P/E ratio. Value investors see such stocks as undervalued.
The current price is the most recent selling price of a stock, currency, commodity, or precious metal that is traded on an exchange and is the most reliable indicator of that security's present value.
The formula consists of taking the DPS in the period by (Required Rate of Return – Expected Dividend Growth Rate). For example, the value per share in Year is calculated using the following equation: Value Per Share ($) = $5.15 DPS ÷ (8.0% Ke – 3.0% g) = $103.00.
Briefly, in order to be eligible for payment of stock dividends, you must buy the stock (or already own it) at least two days before the date of record. That's one day before the ex-dividend date.
Rahul owns a small business selling clothing. He knows that in the last week 87 customers paid cash, 24 customers used a debit card, and 7 customers used a credit card. If next week, he is expecting 1500 customers, about how many would you expect to pay with a credit card? Round your answer to the nearest whole number.
In linear equation,the number of customers who will pay by debit card will be 88.97.
What in mathematics is a linear equation?
An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.
The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times. Known as a linear equation, this type of equation has a highest power of one for each variable.
Last week there were
87 + 24 + 7 = 118 customers.
That means that the fraction of the customers, who paid by debit card, was
7/118
In situations like that, when we use historical data and try to predict future behaviour, we use that past experience and extrapolate to a predicted result.
we simply say that we expect the same fraction, 7/118 if customers use credit cards
for the absolute number of predicted debit card customers we multiply the predicted number of customers by the expected fraction
1500 × 7 / 118 = 88.97
Therefore the number of customers who will pay by debit card will be 88.97.
