Answer:

-9

Step-by-step explanation:

for linear equations, the show off the line is the coefficient of x.

in this case, the slope would be -9

The domain of the relation is x = - 2 and the range of the relation is -2 ≤ y < 1

The range of a relation is the possible values of the output of the relation.

The domain of a relation is the possible value of the input of the relation.

Looking at the graph, we see the only value for x is x = - 2. Since this is the input of the relation.

So, the domain is x = - 2.

Looking at the graph, we see that the minimum value of y is at y = - 2 and its maximum value is at y = 1. Also, we see that the circle at y = - 2 is shaded, so that value of y is included but, the circle at y = 1 is not shaded, so y = 1 is not included.

So, the range is -2 ≤ y < 1

So, the domain of the relation is x = - 2 and the range of the relation is -2 ≤ y < 1

The slope =2 and y-intercept = -3.

What is slope?

Calculated using the slope of a line formula, the ratio of "vertical change" to "horizontal change" between two different locations on a line is determined. The difference between the line's y and x coordinate changes is known as the slope of the line.Any two distinct places along the line can be used to determine the slope of any line.

Here let us take two points \((x_1,y_1)=(1.5,0) , (x_2,y_2)=(0,3)\) .

Now using slope formula then,

Slope m = \(\frac{y_2-y_1}{x_2-x_1}\)

=> m = \(\frac{3-0}{0-1.5} = \frac{3}{-1.5}=2\)

Now using equation formula then,

=> \(y-y_1=m(x-x_1)\)

=> y-0=2(x-1.5)

=> y = 2x-3

Here y=mx+b, where b= y-intercept.

Hence slope =2 and y-intercept = -3.

The sequence is arithmetic. The common difference is 6. Answer: b

If a sequence is arithmetic, there exists a common difference d that is added to each term to get the next term. For instance, given the sequence 2, 5, 8, 11, 14, ...  to get each of the subsequent terms, we add 3. 2 + 3 = 5; 5 + 3 = 8, and so on.

The given sequence is 2,7,13,20, ...To determine whether it is an arithmetic sequence, we need to find the common difference d.

Subtract each subsequent term from its preceding term;7 - 2 = 513 - 7 = 620 - 13 = 7

Answer:

C (1,11) and (-1,-5)

Step-by-step explanation:

According to the given information the line integral is 8(1+125\(\sqrt{110}\)) / 15 .

What distinguishes a line integral from a definite integral?

Line integrals include several integrals across a curve, but definite integrals only entail a single integral over a specified interval. This is the primary distinction between the two types of integrals.

\(\int\limits_c {xy} \, ds\),  C : x = t^2 , y = 2t,  0 ≤ t ≤ 3

x' = 2t , y' = 2

ds = \(\sqrt{(x')^2 + (y')^2}\)

\(\sqrt{4(t)^2 + 4}\)

\(\int\limits C {xy} \, ds\) = \(\int\limits^3_0 {2.2t.2\sqrt{1+t^2}} \, dt\)

t = tanθ

dt = (1+\(tan^{2}\)θ)dθ = (\(sec^{2}\)θ)dθ

= \(\int\limits^3_0 {4t^3\sqrt{1+t^2} } \, dt\)

= 8(1+125\(\sqrt{110}\)) / 15

If all the conditions are met to conduct a hypothesis test, the null and alternative hypotheses are given below:

Option d. H0 : μ= 0 minutes, H1 : μ≠ 0 minutes is the correct answer.

A statistical hypothesis test is a method of making a statistical decision using experimental data. Hypothesis testing is a way to infer about a population using data gathered from a sample. The process involves several steps, including stating the null and alternative hypotheses.

The first step in hypothesis testing is to state the null hypothesis (H0) and the alternative hypothesis (H1). The null hypothesis represents the assumption that there is no significant difference or effect in the population. It assumes that any observed difference or effect is due to random chance.

In this case, the null hypothesis is stated as H0 : μ = 0 minutes, where μ represents the population mean. This means that the population mean is assumed to be zero minutes.

The alternative hypothesis (H1) is the hypothesis that contradicts the null hypothesis. It represents the possibility of a significant difference or effect in the population. In this case, the alternative hypothesis is stated as H1 : μ ≠ 0 minutes, indicating that the population mean is not equal to zero minutes.

The choice of the alternative hypothesis depends on the research question and the specific hypothesis being tested. It could be a two-tailed test, as indicated by the "≠" symbol in the alternative hypothesis, suggesting that the population mean could be significantly greater than or less than zero minutes.

After stating the null and alternative hypotheses, the significance level (α) is determined, which represents the probability of rejecting the null hypothesis when it is actually true. The significance level helps in making a decision about the null hypothesis based on the calculated test statistic and p-value.

In conclusion, option d. H0 : μ = 0 minutes, H1 : μ ≠ 0 minutes is the correct answer for the null and alternative hypotheses in this context.

The Taylor series for f(x) is f(x) = x + (1/3)x^3 + (2/15)x^5 . The Taylor series for f(x) = tan(x) centered at x = 0 can be computed by differentiating tan(x) multiple times and evaluating the derivatives at x = 0.

However, since this process can be quite tedious, it is more efficient to use computational tools like Wolfram Alpha to compute the derivatives and the Taylor series directly. Using Wolfram Alpha, the derivatives of tan(x) at x = 0 are:

f(0) = 1

f(0) = 0

f(0) = 2

f(0) = 0

f(0) = 16

Substituting these values into the formula for the Taylor series, we can compute the Taylor series for f(x) centered at x = 0 up to the x^5 term. The Taylor series for f(x) is:

f(x) = x + (1/3)x^3 + (2/15)x^5

Comparing this series to the Taylor series computed using Wolfram Alpha, we can see that they agree. The Taylor series contains only odd powers of x (x, x^3, x^5), while tan(x) is an odd function. This agreement between the series and the nature of tan(x) being odd is expected.

Using Desmos to plot both tan(x) and the power series approximation on the same graph, we can see that the power series approximation "looks good" around the interval [-π/2, π/2] (excluding the vertical asymptotes). Within this interval, the power series provides a reasonable approximation to the behavior of tan(x).

Step-by-step explanation:

since there is no graph it's a bit hard to answer this question, but I'll try. I can help solve the equation that represents the ratio of the two numbers:

(x + 1/2)/y = 1/3

This can be simplified to:

x + 1/2 = y/3

To graph this equation, you would need to plot points that satisfy the equation. One way to do this is to choose a value for y and solve for x. For example, if y = 6, then:

x + 1/2 = 6/3

x + 1/2 = 2

x = 2 - 1/2

x = 3/2

So one point on the graph would be (3/2, 6). You can choose different values for y and solve for x to get more points to plot on the graph. Once you have several points, you can connect them with a line to show the relationship between x and y.

We may determine that the triangles are congruent based on the (B) HL criterion right away.

According to the HL Postulate, a right triangle's hypotenuse and leg are congruent if they are also congruent with the hypotenuse and leg of another right triangle.

So, we can see from the accompanying figure that these two triangles share a center line that is parallel to the base.

The two triangles are therefore right-angled triangles.

The hypotenuse of two triangles being congruent is then mentioned as a further argument.

Triangle congruence according to the HL criterion allows for a quick determination of congruence.

An ice cream shop has 10 flavors and one can choose 4 different flavors. The question asks for the total number of possible flavor combinations.Therefore, we need to find the number of ways in which 4 flavors can be chosen from 10 flavors.

In such cases where order does not matter and repetitions are not allowed, we can use the formula for combinations which is as follows:C(n, r) = n! / (r! (n - r)!)Where n is the total number of items, r is the number of items being chosen at a time and ! represents the factorial function.

Using this formula we can find the total number of possible flavor combinations. Substituting the values in the above formula, we get:C(10, 4) = 10! / (4! (10 - 4)!)C(10, 4) = (10 * 9 * 8 * 7) / (4 * 3 * 2 * 1)C(10, 4) = 210Hence, there are 210 possible flavor combinations when one can choose 4 different flavors

.Explanation:The formula to be used for this type of question is combination. Combination is the method of selecting objects from a set, typically without replacement (without putting the same item back into the set) and where order does not matter.

The percentage of model A cars sold that are gray is 23.8% and the percentage of red cars sold that are model B is 55.6%.

The percentage of model A cars sold that are gray can be calculated by dividing the number of gray model A cars by the total number of model A cars sold, and then multiplying by 100.

From the table, we can see that there were 5 gray model A cars sold. To find the total number of model A cars sold, we need to add up the values in the first row of the table, which gives us 9 + 12 = 21.

So, the percentage of model A cars sold that are gray is (5/21) * 100 = 23.8%.

To find the percentage of red cars sold that are model B, we need to divide the number of red model B cars by the total number of red cars sold, and then multiply by 100.

From the table, we can see that there were 10 red model B cars sold. To find the total number of red cars sold, we need to add up the values in the second column of the table, which gives us 5 + 3 + 10 = 18.

So, the percentage of red cars sold that are model B is (10/18) * 100 = 55.6%.

Answer:

$1053

Step-by-step explanation:

If we have that £1 = $1.62, then we can multiply both sides by 650 in order to get £650 on the left side of the equality. We must multiply the right side also by 650, and so we get £650=$1.62 * 650.

To do this multiplication, we can break 1.62 down  simply into $1.00 +$0.6+$0.02

650*$1.00=$650, 650*$0.6=650*6/10=65*6=$390, and 650*$0.02=650*2/100=6.5*2=$13.

When we add these three products together, we get $650+$390+$13=$1053. And so, £650=$1053
