A rose garden is formed by rectangular and semi-circular parts. If the gardener wants to build a fence around the garden, then total 134.95 feet of fence are required.

The perimeter is defined as calculating the outer length of boundaries of shape.

We have a rose garden is formed by joining a rectangle and a semicircle, as present in above figure. We have to determine the feet of fence are required to build a fence around the garden.

From the above figure, length of rectangular part, l = 34 ft

Width of rectangular part, w = 26 ft.

Also, diameter of semi-circular part, d

= 26 ft

Radius of of semi-circular part, r = d/2

= 26/2 ft = 13 ft

So, the perimeter of semi-circular part, Pₛ= π× r = π× 13 ft

= 40.95 ft.

Here, the fence required for the rectangle shape is three sides that two long sides and one wide side. The fourth side of the width is already covered by the semi-circular part. So, the perimeter formula for the rectangle shape, Pᵣ = 2l + w. Therefore, perimeter of garden

= Pₛ + Pᵣ

= 40.95 ft + 2×34 ft + 26 ft

= 68 ft + 26 ft + 40.95 ft

= 134.95 ft.

Hence, required value is 134.95 feet.

The null hypothesis is denoted by the symbol H0, not H1. The null hypothesis is a statement that is typically formulated in terms of population parameters or characteristics, not sample statistics. It states that there is no significant or meaningful effect or relationship between variables or treatments under investigation.

The alternative hypothesis (H1 or Ha) is the complementary statement to the null hypothesis, representing the claim or hypothesis that contradicts the null hypothesis. The alternative hypothesis is often formulated to suggest that there is a significant effect or relationship present.

The null hypothesis, denoted by the symbol H0, is a fundamental concept in hypothesis testing and statistical inference. It is formulated as a statement about the population parameters or characteristics under investigation. The null hypothesis typically assumes that there is no significant effect, difference, or relationship between variables or treatments being studied.

In statistical hypothesis testing, researchers aim to gather evidence to either reject or fail to reject the null hypothesis. If the evidence is strong enough, the null hypothesis is rejected in favor of the alternative hypothesis, suggesting that there is a significant effect or relationship present.

The alternative hypothesis, denoted by H1 or Ha, is the complement to the null hypothesis. It is usually stated as the hypothesis that contradicts the null hypothesis and supports the researcher's claim or hypothesis. The alternative hypothesis asserts that there is a significant effect, difference, or relationship between variables or treatments.

It is important to note that the formulation of the null and alternative hypotheses depends on the research question and the specific context of the study. The null hypothesis is essential in hypothesis testing as it provides a baseline against which the alternative hypothesis can be compared and evaluated using statistical methods.

Sin 36= 0.5877

x= 14/sin36

x= 24

a) The value of cos(2x) = 17/25

b) The value of sin(2x) = -8√21/25

c) The value of tan(2x) = ± (2/5) (1 + √21/5) / (1 - √21/5)

Finding the value of cos(x) in Since the sin(x) = 2/5, use the Pythagorean identity to find the value of cos(x).

cos²(x) = 1 - sin²(x)cos²(x)

= 1 - (2/5)²cos²(x)

= 1 - 4/25cos²(x)

= 21/25cos(x)

= ± √(21/25)

x is in Q2, therefore, cos(x) is negative, so:

cos(x) = - √(21/25)cos(x)

= - √21/5

find the values of (a) cos(2x), (b) sin(2x), (c) tan(x/2). Finding the value of cos(2x) Now, use the double-angle identity to find cos(2x).

cos(2x) = cos²(x) - sin²(x)cos(2x)

= (21/25) - (4/25)cos(2x)

= 17/25

Finding the value of sin(2x) Now, use the double-angle identity to find sin(2x).

sin(2x) = 2 sin(x) cos(x)sin(2x)

= 2 (2/5) (-√21/5)sin(2x)

= -8√21/25

Finding the value of tan(x/2) Now, use the half-angle identity to find tan(x/2).

tan(x/2) = ± sin(x) / (1 + cos(x))

tan(x/2) = ± (2/5) / (1 - √21/5)

rationalize the denominator by multiplying the numerator and the denominator by (1 + √21/5).

tan(x/2) = ± (2/5) (1 + √21/5) / (1 - √21/5)(a) cos(2x)

The equation that can be used to find y, the year in which both bodies of water have the same amount of mercury is 0.05 + 0.1y = 0.12 + 0.06y. Hence, the 3rd option is the right choice.

In the question, we have been asked for the equation that can be used to find y, the year in which both bodies of water have the same amount of mercury.

First, we will find the equations showing the level of mercury in each body of water.

For the first water body:

Initial measure of mercury = 0.05 ppb.

Rate of rising = 0.1 ppb each year.

Number of years = y.

Thus, the equation showing level of mercury = 0.05 + 0.1y.

For the second water body:

Initial measure of mercury = 0.12 ppb.

Rate of rising = 0.06 ppb each year.

Number of years = y.

Thus, the equation showing level of mercury = 0.12 + 0.06y.

We are looking for the equation, to find y, the year in which both bodies of water have the same amount of mercury.

As they will have the same amount of mercury, their respective equations showing the level of mercury should be equal, that is:

0.05 + 0.1y = 0.12 + 0.06y, which is the required equation.

Thus, the equation that can be used to find y, the year in which both bodies of water have the same amount of mercury is 0.05 + 0.1y = 0.12 + 0.06y. Hence, the 3rd option is the right choice.

You are solving for x so obviously you have to have your x variable on one side of the equal sign by itself.

So how do you do that? Combine the same calues together and seperate the rest

4x + 2x = 6x

6x = 18 + 6

6x = 24

x = 3

Practice practice practice. Simple stuff. You got this!

Answer:

A. x = 4

Step-by-step explanation:

To answer this question, we first have to combine like terms:

4x - 6 + 2x = 18

6x - 6 = 18

Now, we take away 6 from the left side and add it to the right side:

6x - 6 = 18

     +6   +6

6x = 24

Then, we isolate the variable:

6x = 24

The parametric equations for the motion of the particle in the xy plane that traces the counterclockwise ellipse are x = 6cos(t) and y = 4sin(t), where t is the parameter. The parameter interval for the motion is 0 ≤ t ≤ 2π.

To find the parametric equations for the counterclockwise motion of the particle along the given ellipse, we can start by parameterizing the ellipse equation  \(16x^2 + 9y^2 =\) 144. We divide both sides of the equation by 144 to normalize it, giving us  \((x^2/9) + (y^2/16\)) = 1. By comparing this equation with the standard form of an ellipse, we can see that a = 3 and b = 4.

We can then use the trigonometric parametrization of an ellipse to obtain the parametric equations. Letting x = acos(t) and y = bsin(t), where t is the parameter, we substitute the values for a and b, resulting in x = 6cos(t) and y = 4sin(t). These equations represent the motion of the particle along the ellipse.

Since we want the particle to trace the ellipse counterclockwise, we need to cover the full circumference of the ellipse. This corresponds to a parameter interval of 0 ≤ t ≤ 2π, which completes one full revolution around the unit circle. Therefore, the parametric equations for the motion of the particle are x = 6cos(t) and y = 4sin(t), with a parameter interval of 0 ≤ t ≤ 2π.

Explanation:

We're conducting a one proportion Z test.

The hypothesized population proportion is p = 0.53, which is not to be confused with the p-value (unfortunately statistics textbooks seem to overuse the letter 'p'). Luckily this problem is not asking for the p-value.

The sample population proportion is

phat = x/n = 41/79 = 0.518987 approximately

The standard error (SE) is

SE = sqrt(p*(1-p)/n)

SE = sqrt(0.53*(1-0.53)/79)

SE = 0.056153 approximately

Making the test statistic to be

z = (phat - p)/(SE)

z = (0.518987 - 0.53)/0.056153

z = -0.19612487311452

z = -0.196

The alternative that proportionates the greatest quality of the product R is alternative 3. This can be justified mathematically.

In order to determine the greatest quality of the product R, we need to consider the stoichiometry of the reaction and the conditions of the reactors. The fact that the reaction is elemental in the liquid state means that the reaction is highly dependent on the reactant concentrations and the residence time of the reactants in the reactors.

By using plug flow reactors, we ensure that the reactants flow through the reactors without any mixing or backflow. This allows for better control over the reaction conditions and minimizes side reactions.

Alternative 3, which consists of two reactors, will provide a larger total volume for the reaction compared to the other alternatives. This means that the reactants will have a longer residence time in the reactors, allowing for a higher conversion of reactants to product R.

Additionally, the larger volume in alternative 3 will allow for better temperature and concentration control, leading to a higher quality product R.

Therefore, alternative 3 proportionates the greatest quality of the product R based on the stoichiometry of the reaction and the use of plug flow reactors.

The response variable in this study is a categorical binary variable that measures the preference of the students between two brands of instant coffee.

In mathematics, a variable is referred to as the alphanumeric symbol used to represent a number or numerical value. An unknown quantity is represented as a variable in algebraic equations.

The response variable in this study is the preference of the students between brand A and brand B of instant coffee. The students are asked to try both brands and indicate which one they prefer, so the variable is categorical with two possible outcomes: preference for brand A or preference for brand B.

In statistical research, a response variable is an outcome or result that is being studied or measured. In this particular study, the response variable is the preference of the students between two brands of instant coffee, which are brand A and brand B.

Since the students are asked to try both brands and then indicate their preference, the response variable is categorical because it involves classifying each student's response into one of two possible categories: preference for brand A or preference for brand B.

Furthermore, the response variable is binary since there are only two possible outcomes for each student. The students either prefer brand A or prefer brand B, so the variable takes on one of two values: 0 for preference for brand A or 1 for preference for brand B.

Therefore, the response variable in this study is a categorical binary variable that measures the preference of the students between two brands of instant coffee.
