Answer:

x = 34

Step-by-step explanation:

A straight line is 180 degrees

We can sum angles to form a straight line

x+12 + 100 +x = 180

Combine like terms

2x+112 = 180

2x+112-112 = 180-112

2x = 68

Divide each side by 2

2x/2 = 68/2

x = 34

answer:

=x+12+100+x =180

=x+x+12+100=180

=2x+112=180

=2x=180-112

=2x=68

=2/2x=68/2

=x=34

Step-by-step explanation:

From the information given:

\(r^2 = x^2 +y^2\)

\(r^2 = (-6)^2 + (5)^2\)

\(r^2 = 36 +25\)

\(r^2 =61\)

\(r = \sqrt{61}\)

\(Sin \theta = \dfrac{y}{r} = \dfrac{5}{\sqrt{61}}\)

\(Cos \theta = \dfrac{x}{r} = \dfrac{- 6 }{\sqrt{61}}\)

\(Sec \theta = \dfrac{1}{cos \theta} = \dfrac{\sqrt{61}}{5}\)

\(tan \theta = \dfrac{Sin \theta }{Cos \theta}\)

\(tan \theta = \dfrac{\dfrac{5}{\sqrt{61}} }{\dfrac{{-6} }{\sqrt{61}} }\)

\(tan \theta = {\dfrac{5}{\sqrt{61}} }\times \dfrac{\sqrt{61} }{-6}\)

\(tan \theta = {\dfrac{5}{-6} }\)

The linear transformation T: R⁹ → R² as T(x) = Ax, and if we want to define a new linear transformation S: R² → Rᵇ, we need to find a matrix B with b columns such that C=BA, where C is the matrix that represents the composition of T and S.

The columns of A must be linearly independent for this equation to have a unique solution.

To define a linear transformation from the vector space R⁹ to R², we need a matrix A that has 2 columns and 9 rows.

Let us denote this matrix as A=[a1 a2 ... a9], where each column ai is a 9-dimensional column vector.

Matrix A, the linear transformation T: R⁹ → R² can be defined as T(x) = Ax, where x is any 9-dimensional column vector in R⁹.

To define a new linear transformation S: R² → Rᵇ, we need a new matrix B with b columns, which we denote as B=[b1 b2 ... bb].

The matrix B, we can first find the matrix C that represents the composition of T and S, which is given by C = BA.

Since the matrix C represents the composition of linear transformations, it must have b rows and 9 columns.

B must be a 2x b matrix.

Matrix a must be a b×a matrix, and the input vector x must have a dimensions (a×1) for the linear transformation t(x) = ax to be well-defined.

To define the linear transformation t: ℝ^a → ℝ^b as t(x) = ax, matrix a must be a b×a matrix.

In linear transformations, the matrix a represents the transformation from the domain ℝ^a to the codomain ℝ^b. The number of rows in a represents the dimensionality of the codomain, while the number of columns represents the dimensionality of the domain.

Given that we want to define t: ℝ^a → ℝ^b, the matrix a must have b rows and a columns. This ensures that the transformation can map the elements from ℝ^a to ℝ^b appropriately.

Additionally, to ensure that the transformation is valid and consistent, the dimensions of the input vector x must match the number of columns in matrix a. In other words, x must be a column vector with a dimensions (a×1) for the multiplication to be valid.

False. We do not always evaluate just the specific result obtained in an experiment.

In scientific experiments, we do not just evaluate the specific result obtained in the experiment. Instead, we evaluate the entire experimental design, including the methods used, the sample size, and the statistical analysis.

For example, suppose a researcher conducts an experiment to test a new drug's effectiveness in treating a particular disease. If the result of the experiment shows that the drug is effective, the researcher cannot simply conclude that the drug works based on this one result. Instead, the researcher must evaluate the experimental design to ensure that the result is reliable and valid.

This evaluation includes examining the study's methods to determine if they are appropriate and if the sample size is large enough to produce meaningful results. It also involves statistical analysis to assess the strength of the relationship between the treatment and the outcome and to determine if the result is statistically significant.

Therefore, evaluating just the specific result obtained in an experiment is not sufficient. We must also consider the experimental design, methods used, sample size, and statistical analysis to draw valid and reliable conclusions from the experiment.

Answer:

The answer is 50%

Step-by-step explanation:

The given double integral is ∫ ∫ (x² + y²)dx dy, and we need to evaluate it over the region in the positive quadrant where x+y≤1.

To evaluate this double integral, we can first determine the limits of integration for both x and y based on the given region. In the positive quadrant, x and y both range from 0 to 1.

Now, integrating the inner integral with respect to x, we get:

∫ (x² + y²)dx = (1/3)x³ + y²x + C1,

where C1 is the constant of integration.

Next, we integrate the resulting expression with respect to y:

∫ [(1/3)x³ + y²x + C1] dy = (1/3)x³y + (1/3)y³x + C1y + C2,

where C2 is another constant of integration.

Finally, we evaluate this double integral over the given region by substituting the limits of integration:

∫∫ (x² + y²)dx dy = ∫[0 to 1] ∫[0 to 1-x] (x² + y²)dy dx.

Performing the integration, we can find the numerical value of the double integral within the given region.

Step-by-step explanation:

The correct answer is A. The standard error of the sample proportion will become larger as the sample size increases.

The standard error is a measure of the variability or uncertainty associated with an estimate. In the case of the sample proportion, it measures the spread or variability in the proportion of successes observed in the sample compared to the true population proportion.

As the sample size increases, the standard error decreases, indicating greater precision in estimating the true population proportion. This is because a larger sample provides more information and reduces the impact of sampling variability.

On the other hand, options B, C, and D are incorrect. The standard error is not affected by the population proportion itself but rather by the sample size. The population proportion approaching 0.50, 1.00, or 0 does not directly impact the standard error, although it may affect other measures such as the margin of error or confidence intervals. The primary factor influencing the standard error is the sample size, with larger samples leading to smaller standard errors.

Answer: 16.1 cm

Step-by-step explanation:

Attached below is a diagram of the triangle.

If you have two legs, you can find the hypotenuse of the right triangle by using the Pythagorean Theorem.

Pythagorean Theorem: a² + b² = c²

Let's set

a = 16 cm

b = 2 cm

So we get,

16² + 2² = c²

256 + 4 = c²

260 = c²

Take the square root of both sides to get c. Since you are taking the square root, there are two answers, positive and negative, but a side length can not be negative.

\(\sqrt{260}\) = c

Input this into your calculator, and you get

c = 16.1245155 cm

Rounding to the nearest tenth you get c = 16.1 cm

The limit is infinity, which is greater than 1, the ratio test fails to establish convergence. Therefore, we can conclude that the series Σ n! / 105! diverges.

To determine the convergence of the series Σ n! / 105!, we can apply the ratio test.

The ratio test states that if the limit of the absolute value of the ratio of consecutive terms in a series is less than 1, then the series converges. If the limit is greater than 1 or it does not exist, then the series diverges.

Let's apply the ratio test to the given series:

aₙ = n! / 105!

aₙ₊₁ = (n+1)! / 105!

Taking the ratio of consecutive terms:

|aₙ₊₁ / aₙ| = [(n+1)! / 105!] / [n! / 105!]

= (n+1)! / n!

= n+1

Taking the limit as n approaches infinity:

lim(n→∞) (n+1) = ∞

Since the limit is infinity, which is greater than 1, the ratio test fails to establish convergence. Therefore, we can conclude that the series Σ n! / 105! diverges.

We are given that;

The statement

Now,

The value of -sec x is positive when -cos x is positive and negative when -cos x is negative.

This is because the secant function is the reciprocal of the cosine function, so \($sec x = \frac{1}{cos x}$\)

Hence, \($-sec x = -\frac{1}{cos x} = \frac{1}{-cos x}$.\)

The sign of a fraction depends on the sign of its numerator and denominator.

If both are positive or both are negative, the fraction is positive. If one is positive and the other is negative, the fraction is negative.

So, when -cos x is positive, \($\frac{1}{-cos x}$\) is negative, and when -cos x is negative, \($\frac{1}{-cos x}$\) is positive.

The difference in the account balance between a simple interest and a compound interest over an 8-year time period, rounded to the nearest cent, is $12,189.02.

To calculate the difference in the account balance between simple interest and compound interest over 8 years, we first need to determine the final balance for each case.

Simple Interest:

Simple interest is calculated as a percentage of the initial principal (or the original amount deposited) and is paid only on the principal amount. The formula for simple interest is:

I = P * r * t

where I is the interest earned, P is the principal amount (in this case, $5,000), r is the annual interest rate (as a decimal), and t is the time period in years.

For this problem, the interest rate is given as 31%, which is equivalent to 0.31 as a decimal. Therefore, we have:

I = $5,000 * 0.31 * 8 = $12,400

The final balance for simple interest is the sum of the principal and the interest earned:

Final balance (simple interest) = $5,000 + $12,400 = $17,400

Compound Interest:

Compound interest is interest that is calculated on both the principal amount and any accumulated interest. The formula for compound interest is:

A = P * (1 + r/n)^(n*t)

where A is the final amount, P is the principal amount, r is the annual interest rate (as a decimal), n is the number of times per year that interest is compounded, and t is the time period in years.

For this problem, the interest rate is 31% and the account is compounded annually, so n = 1. Therefore, we have:

A = $5,000 * (1 + 0.31/1)^(1*8) = $29,589.02

The final balance for compound interest is the amount we just calculated:

Final balance (compound interest) = $29,589.02

The difference in the two account balances is:

$29,589.02 - $17,400 = $12,189.02

Therefore, the difference in the account balance between a simple interest and a compound interest over an 8-year time period, rounded to the nearest cent, is $12,189.02.
