In a basic sine curve, where can the zeros NOT be found?
a. middle
b. beginning
c. maximum point
d. end
Answer: Option 'C' is correct.
Step-by-step explanation:
Since we know that
[tex]f(x)=\sin x[/tex]
It is an odd function.
It has a period of 2π because the sine wave repeats after every 2π units.
It value lies between -1 and 1.
And we know that
[tex]\sin 0^\circ=0^\circ[/tex]
And 0 occurs exactly middle of -1 and 1.
So, the zeroes can be found in the middle, beginning and at the end.
But at maximum point, there will be no zero.
As when it attains its maximum point, it won't touch x-axis.
Hence, Option 'C' is correct.

What is the following product?
3 sqrt24 * 3sqrt 45
The product of 3√24 and 3√45 is approximately 295.77.
Explanation:To find the product, we can first simplify the individual square roots.
√24 = √(4 * 6) = 2√6
√45 = √(9 * 5) = 3√5
Substitute the simplified terms: 3 * 2√6 * 3 * 3√5 = 18√30
Factor out a 9: 18√30 = 9 * 2√(10 * 3)
Simplify the remaining square root: 9 * 2√30 ≈ 9 * 2 * 5.477 = 295.77 (rounded to two decimal places).
Therefore, the product of 3√24 and 3√45 is approximately 295.77.

Formulate a decision model to determine whether there are any arbitrage opportunities with the spot currency rates given in table 1. note that an arbitrage opportunity could involve several currencies. if there is an arbitrage opportunity, your model should specify the exact set of transactions to achieve it. to us dollar pound ffranc dmark yen us dollar - 0.63900 5.37120 1.57120 98.8901 pound 1.56480 - 8.43040 2.45900 154.7733 from ffranc 0.18560 0.11860 - 0.29210 18.4122 dmark 0.63610 0.40630 3.42330 - 62.9400 yen 0.01011 0.00645 0.05431 0.01588 - table 1: cross-currency spot rates
Final answer:
To determine if there's an arbitrage opportunity, convert an amount through various currencies in the table and see if you end with more than you started. If more is ended up with, there's an opportunity, specifying the currencies and transactions. If not, the market is in equilibrium, and rates will adjust to prevent arbitrage.
Explanation:
To identify an arbitrage opportunity within the given spot currency rates, one must find a sequence of exchanges that results in more currency than initially started with, after accounting for the currency exchange rates in table 1. The decision model for discovering an arbitrage opportunity typically involves converting an amount from one currency to another across several pairs and ending up with more than one started with in the original currency. The following steps outline the process to determine if arbitrage is possible:
Start with a denomination of one currency (e.g., $1).
Convert this amount into another currency using the provided spot rates.
Repeat the conversion process for subsequent currencies.
Finally, convert back to the original currency.
If the final amount is greater than the starting amount, an arbitrage opportunity exists. In such a scenario, the model should indicate the currencies involved and the specific transactions to execute the arbitrage. However, if no sequence of transactions results in profit, then no arbitrage opportunity is present given the rates provided. The absence of arbitrage ensures that the markets are in equilibrium, and the exchange rates will adjust to eliminate any potential for arbitrage as per the efficient market hypothesis.

robert ordered 11 pizzas for a pizza party for the softball team. when he ordered the pizzas, he told members they could each eat 3/5 of a pizza. if each person gets 3/5 of a pizza, how many people can eat this much pizza at the party
Final answer:
18 people can eat 3/5 of a pizza, with a little pizza left over.
Explanation:
To find out how many people can eat 3/5 of a pizza at the party, we need to divide the total number of pizzas by the fraction each person can eat.
Number of people who can consume 3/5 of a pizza = Total pizzas / (3/5)Number of people = 11 / (3/5)Number of people = 11 / (3/5) = 11 * (5/3) = 55/3 = 18.33Therefore, approximately 18 people can eat 3/5 of a pizza at the party.

Lesson 8 homework practice solve percent problems
To solve percent problems, we can use equivalent fractions, cross-multiply, solve for the unknown, or convert percent to a fraction and simplify. In context, a 24% positive rate among students indicates that 24 out of every 100 students are positive.
Explanation:In mathematics, specifically in percentage calculation, there are several methodologies to solve problems. One very common way, as mentioned in the reference material, is by setting up equivalent fractions with 100 as the denominator, and cross-multiplying. For example, if you have the fraction 9/37 representing some scenario (like 9 successful attempts out of 37), you can set up an equation like 9/37 = x/100, where 'x' is the equivalent percentage. Cross-multiply and solve for 'x' to get x = (9/37) * 100, giving you the percentage.
Also, note that a percent can be converted to a fraction by writing the value of the percent as a fraction with a denominator of 100. Simplify the fraction, if possible.
In context, if 24% of students are positive, that means for every 100 students, 24 would be positive. If only 70 are surveyed, then (24/100)*70 = 16.8 students, but since we can't have a part of a student, we would round it to 17 students are positive for this sample size.

Bill's new porch is rectangular, with an area of 50 square feet. If the length of the porch is two times the width, what is the perimeter of the porch?
The width of the porch is 5 feet and the length is 10 feet. The perimeter of the porch is 30 feet.
Explanation:To find the perimeter of the porch, we first need to find the dimensions of the porch. Let's assume the width of the porch is x feet. According to the problem, the length of the porch is two times the width, so the length would be 2x feet. Since the area of the porch is 50 square feet, we can set up the equation: x * 2x = 50. Simplifying this equation, we get 2x^2 = 50. Divide both sides by 2 to isolate x^2: x^2 = 25. Taking the square root of both sides, we find that x = 5. Therefore, the width of the porch is 5 feet and the length is 2 * 5 = 10 feet.
To find the perimeter, we use the formula: perimeter = 2 * (length + width). Substituting the values, we get perimeter = 2 * (10 + 5) = 2 * 15 = 30 feet. So, the perimeter of the porch is 30 feet.
