y=sin 20 find the period

The ordered pair (1, 2.7) is a solution to y = 0.7x + 2. The flowers may or may not reach the same height.

The main condition y = 0.7x + 2 addresses the level of blossoms after x days in the event that they develop at a pace of 0.7 inches each day and begin at a level of 2 inches. The second condition y = 0.4x + 2 addresses the level of blossoms after x days on the off chance that they develop at a pace of 0.4 inches each day and begin at a level of 2 inches.

To check which requested pair is an answer for the framework, we really want to substitute the x and y values from each arranged pair into the two conditions. Just (0, 2) is an answer, as it fulfills the two conditions. (1, 2.7) and (1, 2.4) don't fulfill the two conditions.

The blossoms won't ever arrive at a similar level since they are developing at various rates. The pace of development of the principal condition (0.7 inches each day) is quicker than the pace of development of the subsequent condition (0.4 inches each day).

The y-catch of every situation addresses the beginning level of the blossoms, which is 2 creeps in the two cases. This truly intends that at day zero (x = 0), the level of the blossoms is 2 creeps for the two conditions. As the worth of x builds, the level of the blossoms will increment at various rates in light of the development rate in every situation.

Answer:

y > 10

Step-by-step explanation:

1/2y>5​

Multiply each side by 2

2* 1/2y>5​*2

y > 10

Answer:

y > 10

Step-by-step explanation:

Inequality:

1/2y>5​

We need to isolate the variable y.

Since it is being multiplied by 1/2, we need to multiply by the reciprocal, or opposite, on both sides. The reciprocal of 1/2 is 2. (Check by multiplying both numbers and making sure the product is 1.)

Multiply:

1/2y>5​

x2     x2

y > 10

Therefore, the simplified inequality is y > 10.

The equation for the hyperbola with foci (0,±5) and asymptotes y=± 3/4 x is:

y^2 / 25 - x^2 / a^2 = 1

where a is the distance from the center to a vertex and is related to the slope of the asymptotes by a = 5 / (3/4) = 20/3.

Thus, the equation for the hyperbola is:

y^2 / 25 - x^2 / (400/9) = 1

or

9y^2 - 400x^2 = 900

The center of the hyperbola is at the origin, since the foci have y-coordinates of ±5 and the asymptotes have y-intercepts of 0.

To graph the hyperbola, we can plot the foci at (0,±5) and draw the asymptotes y=± 3/4 x. Then, we can sketch the branches of the hyperbola by drawing a rectangle with sides of length 2a and centered at the origin. The vertices of the hyperbola will lie on the corners of this rectangle. Finally, we can sketch the hyperbola by drawing the two branches that pass through the vertices and are tangent to the asymptotes.

The length of James' rectangular yard is 96 inches. To find the length of James' rectangular yard in inches, we need to use the perimeter formula, which is given as p = 2l + 2w. In this case, the perimeter is 20 feet.

Since 1 foot is equal to 12 inches, we can convert the perimeter to inches: 20 feet * 12 inches/foot = 240 inches.
We also know that the width of the yard is 2 feet, so we can convert it to inches: 2 feet * 12 inches/foot = 24 inches.
Now, we can substitute the values into the perimeter formula: 240 inches = 2l + 2 * 24 inches.
Simplifying the equation: 240 inches = 2l + 48 inches.
Subtracting 48 inches from both sides: 192 inches = 2l.
Dividing both sides by 2: 96 inches = l.
Therefore, the length of James' rectangular yard is 96 inches.
The length of James' rectangular yard is 96 inches.
To find the length of James' rectangular yard in inches, we can use the perimeter formula, which is given as p = 2l + 2w. In this case, the perimeter of his fence is 20 feet.

To convert the perimeter to inches, we need to multiply it by the conversion factor of 12 inches per foot.

So, 20 feet * 12 inches/foot = 240 inches. Next, we can find the width of the yard, which is given as 2 feet.

Again, we can convert it to inches by multiplying by 12 inches per foot: 2 feet * 12 inches/foot = 24 inches.

Now, we can substitute the values into the perimeter formula: 240 inches = 2l + 2 * 24 inches.

Simplifying the equation gives us 240 inches = 2l + 48 inches. To isolate the variable, we subtract 48 inches from both sides: 192 inches = 2l.

Finally, dividing both sides by 2 gives us the length of James' rectangular yard in inches: 96 inches.
Therefore, the length of James' rectangular yard is 96 inches.

The probability that both numbers are prime is 0.16

What is probability ?

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

Have given,

Total integers(S) = {1,2,3,4,5,.......,20} , n = 20

Prime integers(E) = {2,3,5,7,11,13,17,19} , n = 8

If two different integers are chosen at random,

Then probability of prime integers P(E) = \(\frac{n(S)}{n(E)} *\frac{n(S)}{n(E)}\)

⇒\(\frac{8}{20} *\frac{8}{20}\)

⇒\(\frac{64}{400}\)

⇒ 0.16

Hence , The probability that both numbers are prime is 0.16

The answer is A. √145.

What is magnitude of vector?
The length of a vector determines its magnitude. The letter |a| stands for the vector's magnitude.

The vector 2QS is obtained by multiplying the vector QS by 2. The magnitude of a vector (a, b) is given by the formula √(a² + b²). So we need to find the vector QS and then multiply its magnitude by 2.

The vector QS can be obtained by subtracting the coordinates of Q from the coordinates of S:

QS = (2 - 3, -8 - 4) = (-1, -12)

The magnitude of QS is:

|QS| = √((-1)² + (-12)²) = √(1 + 144) = √145

So the magnitude of 2QS is:

|2QS| = 2|QS| = 2√145

Therefore, the answer is A. √145.

The correct answer is (a) there is a 95% chance that the interval (51%, 57%) contains the true percent of American adults who do not think that human beings developed from earlier species.

The margin of error, stated as 3% in the Harris Poll, is associated with a 95% confidence level. This means that in repeated sampling, 95% of the confidence intervals generated would contain the true proportion of American adults who do not believe in human evolution. Therefore, answer (a) is the correct interpretation of the margin of error.

Answer (b) is incorrect because the margin of error does not imply that the poll's estimate will be within 3% of the true proportion in 95% of cases. The margin of error only pertains to the width of the confidence interval, not the individual estimates.

Answer (c) is also incorrect because the margin of error only applies to the specific poll conducted and does not guarantee that the results of a future poll would fall within the same range.

Answer (d) is incorrect because the margin of error does not indicate the probability of the interval being correct. It is associated with the level of confidence, not the probability of correctness.

Step-by-step explanation: a) To determine for how many years should the company use the new machine to maximize its net savings, we need to find the value of x that maximizes the difference between the savings and the costs.To do this, we need to first calculate the net savings, N(x), which is given by:S'(x) - C'(x) = 175 - x² - (x² + 11x) = -2x² - 11x + 175To find the maximum value of N(x), we need to find the critical values, which are the values of x that make N'(x) = 0:N'(x) = -4x - 11 = 0 ⇒ x = -11/4The critical value x = -11/4 is not a valid solution because x represents the number of years of operation of the machine, which cannot be negative. (i.e., not use it at all).However, this answer does not make sense because the company would not introduce a new machine that it does not intend to use. Therefore, we need to examine the concavity of N(x) to see if there is a local maximum in the feasible interval.

The supply of average eggs is decreasing at a rate of approximately -550 cartons per week as the price decreases 7 cents per carton per week.

The equation given states that the weekly supply x (in thousands of cartons) of a certain brand of medium-sized eggs is related to the wholesale price p (in dollars/carton) by the following equation: 625p2 − x2 =100. In order to determine the rate at which the supply is changing, we must first calculate the value of p when x = 37,000, which is the number of cartons available at the beginning of the week. To do this, we can solve the equation for p when x = 37,000\(p = (100 + x2)1/2/625\). When x=37,000, p=3.65. Therefore, if the price is falling at the rate of 7¢/carton/week, then the new price p = 3.65 - 0.07 = 3.58. When we plug this new value of p into the supply equation, we get\(x^2\) = 4,225. Taking the square root of both sides gives us x = 65. Therefore, the supply is decreasing at a rate of approximately -550 cartons per week as the price decreases 7 cents per carton per week.
