A point on the terminal side of angle 0 is given. Find the exact value of the indicated trigonometric function of 0. (9,12) Find csc 0.

Answers

Answer 1

Given a point on the terminal side of an angle, (9, 12), we can find the exact value of the cosecant (csc) of the angle. The exact value of csc(θ) is 13/9.

To find the exact value of csc(θ), we need to use the given point (9, 12) on the terminal side of angle θ.

The cosecant function (csc) is defined as the reciprocal of the sine function (sin). Since the sine of an angle is given by the ratio of the opposite side to the hypotenuse in a right triangle, we can determine the value of csc(θ) by calculating the ratio of the hypotenuse to the opposite side.

In this case, the coordinates of the point (9, 12) represent the lengths of the sides of a right triangle. The opposite side is 12 and the hypotenuse is the length of the hypotenuse is the distance from the origin (0, 0) to the point (9, 12), which can be calculated using the Pythagorean theorem.

Using the Pythagorean theorem, we find that the hypotenuse is √(9^2 + 12^2) = √(81 + 144) = √225 = 15.

Therefore, the exact value of csc(θ) is the reciprocal of the sine of the angle θ, which is 13/9.

A spherical globe has a diameter of 10 inches. What is the approximate volume of the globe?

Answers

Answer:

523.33 in^3

Step-by-step explanation:

A sphere is a 3-dimensional version of a circle. An example of a sphere is a ball

Volume of a sphere = [tex]\frac{4}{3}[/tex]π[tex]r^{3}[/tex]

Where

π = 3.14

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

diameter = 2r

Radius = 10 in / 2 = 5 inches

[tex]\frac{4}{3}[/tex] × 3.14 ×[tex]5^{3}[/tex] = 523.33 [tex]in^{3}[/tex]

Determine whether the given differential equation is exact. If it is exact, solve it. (If it is not exact, enter NOT.) dy/ dx = 9xe^x – y + 6x2

Answers

The given differential equation is not exact. To determine if a differential equation is exact, we need to check if its partial derivatives satisfy a specific condition.

In this case, the given equation is dy/dx = 9xe^x – y + 6x^2. Let's find the partial derivatives of the expression on the right-hand side with respect to y and x.∂/∂y (9xe^x – y + 6x^2) = -1∂/∂x (9xe^x – y + 6x^2) = 9e^x + 12x

The condition for exactness is that these partial derivatives are equal: ∂/∂y (∂/∂x) = ∂/∂x (∂/∂y). However, in this case, we have -1 ≠ 9e^x + 12x, which means the equation is not exact.As the equation is not exact, we cannot directly solve it by finding a potential function. Other methods, such as using integrating factors or applying specific techniques for solving non-exact equations, may be required.

A rod of length 30.0 cm has linear density (mass per length) given by
λ=50.0+20.0 x
where x is the distance from one end, measured in meters, and λ is in grams/ meter.
What is the mass of the rod?

Answers

The  mass of the rod is 15.9 grams.

To find the mass of the rod, we need to integrate the linear density function over the entire length of the rod. The linear density function is given by λ = 50.0 + 20.0x, where x is the distance from one end measured in meters.

The mass of an infinitesimally small element of length dx is given by dm = λ*dx. Substituting the linear density function, we have dm = (50.0 + 20.0x)*dx.

Integrating both sides from x = 0 to x = 0.3 meters (corresponding to the length of the rod), we get:

∫dm = ∫(50.0 + 20.0x)dx
m = ∫(50.0 + 20.0x)dx
m = [50.0x + 10.0x^2] evaluated from x = 0 to x = 0.3
m = 50.00.3 + 10.0(0.3)^2
m = 15.0 + 0.9
m = 15.9 grams.

Therefore, the mass of the rod is 15.9 grams.

What is the simple interest earned on an $4,350 investment for 5 years at a rate of 2%?

Answers

Hey!

A = $4,785.00

I = A - P = $435.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 2%/100 = 0.02 per year.

Solving our equation:

A = 4350(1 + (0.02 × 5)) = 4785

A = $4,785.00

The total amount accrued, principal plus interest, from simple interest on a principal of $4,350.00 at a rate of 2% per year for 5 years is $4,785.00.

In Canada, the rate of inflation (i.E. How much things cost) is about 2.0%/year. In other words, the real value of your money is worth 2.0% less each year. Imagine you have $2250 in savings under your mattress

Answers

Answer:

Step-by-step explanation:

If you have $2250 as against an inflation rate of 2% every year, this then means that after the first year, the value of your money becomes

2250 * 2% =

2250 * 0.02 = 45

2250 - 45 = $2205

At the end second year

$2205 * 2% =

$2205 * 0.02 = 44.1

$2205 - 44.1 = 2160.9

At end of the third year

$2160.9 - 2% =

$2160.9 * 0.02 = 43.218

$2117.682

An economist conducted a study of the possible association between weekly income and weekly grocery expenditures. The particular interest was whether higher income would cause shoppers to spend more en groceries. A random sample of shoppers at a local supermarket was obtained. A questionnaire was administered asking about the weekly income of each shopper's family and their grocery bill for that werk. The gender of each shopper was also obtained. The data below are expenditures and income for 10 selected survey participants. Income Grocery 98 52 201 78 298 108 398 95 481 198 600 99 738 162 805 187 890 105 1023 173 The correlation for these data is given by 0.794 Ob-0.619. 0.649 4.0.735.

Answers

The correlation coefficient for the data is 0.794.

The correlation coefficient measures the strength and direction of the linear relationship between two variables. In this case, the correlation coefficient of 0.794 indicates a strong positive correlation between weekly income and weekly grocery expenditures.

A correlation coefficient value of 0.794 suggests that as the weekly income increases, the weekly grocery expenditures tend to increase as well. The positive correlation implies that shoppers with higher incomes tend to spend more on groceries.

It is important to note that correlation does not imply causation. The study observed a correlation between income and grocery expenditures, but it does not necessarily mean that higher income directly causes shoppers to spend more on groceries. Other factors and variables may also influence grocery spending habits.

In summary, based on the given data, there is a strong positive correlation (0.794) between weekly income and weekly grocery expenditures for the surveyed shoppers.

Using hypothesis testing, determine whether the sample mean is not equal to the block population's mean (R+) with a confidence level of 99%.

Answers

Hypothesis testing is a statistical method used to determine if a hypothesis regarding a population parameter is correct or not.

It is a decision-making process that aids in making decisions about population parameters when only a sample statistic is available. It has the following steps: State the null and alternative hypotheses. Choose the significance level. Determine the critical value or p-value. Calculate the test statistic. Make a decision and state the conclusion. The formula for the test statistic is given, where x is the sample mean, μ is the population mean, s is the sample standard deviation, and n is the sample size. The null and alternative hypotheses for this problem are:H0: μ = R+ (the sample mean is equal to the block population's mean)Ha: μ ≠ R+ (the sample mean is not equal to the block population's mean)We will use a two-tailed test since we are testing whether the sample mean is not equal to the block population's mean.

The significance level is given as 99%. This means that α = 1 - 0.99 = 0.01.The critical value for a two-tailed test with α = 0.01 and degrees of freedom (df) = n - 1 is obtained from a t-distribution table. Since the sample size is not provided, we cannot determine the critical value. The p-value is the probability of obtaining a test statistic at least as extreme as the one observed, assuming that the null hypothesis is true. The p-value for a two-tailed test is given by:

P-value = P(|t| > |t*|)where t* is the test statistic and |t| is the absolute value of the test statistic. Since we do not have the sample size or the test statistic, we cannot calculate the p-value. Therefore, we cannot make a decision and state a conclusion about the hypothesis test.

What is Fundamental Theοrem οf Calculus?

Tο find the value οf f(6), we can use the Fundamental Theοrem οf Calculus. Accοrding tο the theοrem, if f(x) is cοntinuοus οn an interval [a, b] and F(x) is an antiderivative οf f(x) οn that interval, then the definite integral οf f(x) frοm a tο b is equal tο F(b) - F(a).

Given that f'(x) is cοntinuοus, we can apply the theοrem tο the integral:

∫₅₆ f'(x) dx = f(6) - f(5)

We are given that ∫₅₆ f'(x) dx = 19, and f(5) = 11. Plugging in these values, we have:

19 = f(6) - 11

Tο sοlve fοr f(6), we add 11 tο bοth sides:
