Using L'Hopital's rule, we can find that the limit is equal to (g(0) - 3)/2.

Since the line tangent to g at (0,3) has slope 2, we know that g(0) - 3 = 2(0) = 0. Therefore, the limit is 0/2 = 0. Based on the given information, we have a twice-differentiable function g(x) and its tangent line at the point (0,3). To find the value of the limit as x approaches 0 for g(x)e^(-x) - 3x^2 - 2x, we can use L'Hopital's rule since it involves indeterminate forms of the type 0/0 or ∞/∞.  Apply L'Hopital's rule twice on the given expression. Then, evaluate the resulting expression at x=0. This will give you the value of the limit for the given expression. Make sure to check if the conditions for using L'Hopital's rule are met before applying it.

The logical expressions p⊕q (exclusive OR) and p∨q (inclusive OR) have different truth values when the values of p and q are such that either one of them is true while the other is false.

The exclusive OR (⊕) is a logical operation that returns true if and only if exactly one of the operands is true. In other words, it is true when the values of p and q are different.

On the other hand, the inclusive OR (∨) is a logical operation that returns true if at least one of the operands is true. It is true when either p, q, or both are true.

Therefore, the expressions p⊕q and p∨q have different truth values when one of the following conditions is met:

p is true and q is false.

p is false and q is true.

In these cases, p⊕q will evaluate to true (1), indicating that the values of p and q are different. On the other hand, p∨q will also evaluate to true (1) because at least one of the operands is true, regardless of whether the values of p and q are the same or different.

The graph on the right depicts the linear function y=2x.

Linear function graph is a straight line that depicts linear function y = f(x) = mx + k. It tells the dependent variable y changes by a constant amount as the independent variable x also changes by a constant amount. Whilst variable k is the y-intercept.

The slope of the graph, m, is determined by:

m = (y₂-y₁) / (x₂-x₁)

We are given two graphs. The left graph depicts the line y=x. We want to know what the right graph depicts.

Firstly, we pick two random points on the left graph to find the slope of the graph. Let's say we pick (1,2) and (5,10).

m = (y₂-y₁) / (x₂-x₁)

   = (10-2) / (5-1)

   = 8 / 4

   = 2

Then we find the y-intercept (k), the point where the graph intersects the y-axis. Its value is 0.

Now we put the value of m and k into the linear function:

y = f(x) = mx + k

           = 2x + 0

           = 2x

Thus, the graph on the right shows the line y=2x

It generally takes more effort to cool something quickly compared to cooling it slowly. This is because cooling something quickly requires a larger difference in temperature between the object and its surroundings.

When an object is cooled slowly, the temperature difference between the object and its surroundings is relatively small. This means that heat is transferred at a slower rate, requiring less effort to cool the object. In contrast, when an object is cooled quickly, the temperature difference between the object and its surroundings is larger. This leads to a faster rate of heat transfer and requires more effort to cool the object.

To understand this concept, let's consider an example. Imagine you have a cup of hot water and you want to cool it down. If you place the cup in a room temperature environment, the temperature difference between the hot water and the room is relatively small. As a result, the cup of hot water will cool down slowly.

However, if you want to cool the cup of hot water quickly, you could place it in a refrigerator or pour it over a container of ice. In these scenarios, the temperature difference between the hot water and the cold environment is larger, leading to a faster rate of heat transfer and thus, faster cooling.

In summary, cooling something quickly requires a larger temperature difference and therefore more effort compared to cooling it slowly.

Answer:

f (x) = 1

substitute 1 for x

f (1) = 3 (1) - 4

= 3 - 4

= -1

Answer:

\(y = \frac{ x + 4}{3} \)

Step-by-step explanation:

Let f(x) =y

y= 3x-4

[interchanging variables]

x=3y-4

[making y the subject]

3y=x+4

Therefore the inverse of the function is

\(y = \frac{x + 4}{3} \)

Answer:

Step-by-step explanation:

The calculated t-value for the independent samples t-test (-1.709) is within the range of the critical t-value at α = 0.05 and df = 55. Therefore, we fail to reject the null hypothesis, indicating no significant difference in anxiety levels between bullies and victims.

To determine the exact answer, we can perform a two-sample t-test to compare the means of the bully group and the victim group. The formula for the t-test statistic is:

t = (x₁ - x₂) / √((s₁² / n1) + (s₂² / n₂))

Where

x₁ and x₂ are the sample means of the bully group and victim group, respectively.

s₁ and s₂ are the sample standard deviations of the bully group and victim group, respectively.

n₁ and n₂ are the sample sizes of the bully group and victim group, respectively.

Given the following data:

Bully group: n₁ = 30, x₁ = 21.5, s₁ = 10

Victim group: n₂ = 27, x₂ = 25.8, s2 = 9

Let's calculate the t-test statistic:

t = (21.5 - 25.8) / √((10² / 30) + (9² / 27))

Calculating the values within the square root

t = (21.5 - 25.8) / √((100 / 30) + (81 / 27))

= (21.5 - 25.8) / √(3.333 + 3)

Now, evaluating the square root and simplifying further:

t = (21.5 - 25.8) / √(6.333)

= (21.5 - 25.8) / 2.516

Finally, computing the numerator and denominator:

t = -4.3 / 2.516

≈ -1.709

Therefore, the exact value of the t-test statistic is approximately -1.709.

To compare the calculated t-value (-1.709) with the critical t-value at a significance level of α = 0.05 with a two-tailed test, we need to determine the degrees of freedom (df) first.

The degrees of freedom (df) for the independent samples t-test is given by the formula:

df = n₁ + n₂ - 2

In this case, n₁ = 30 (number of bullies) and n2 = 27 (number of victims). Therefore:

df = 30 + 27 - 2

df = 55

Next, we need to find the critical t-value from the t-distribution table or a statistical software for a two-tailed test at α = 0.05 and df = 55.

For a two-tailed test at α = 0.05 and df = 55, the critical t-value is approximately ±2.004.

Since the calculated t-value (-1.709) is within the range of the critical t-value (-2.004 to 2.004), we fail to reject the null hypothesis. This means that there is not enough evidence to conclude that there is a significant difference in anxiety levels between bullies and victims.

Step-by-step explanation:

By vertical line test the relation represented by given curved graphs is a function.

A relation is said to be a well defined function if one element of domain set is related to exactly one element of codomain.

Here it is clear that if we draw a vertical line at any point that line cuts through only one point of the curve.

So vertical line test shows that one point of X axis i.e. one element of domain is related to one point on Curve i.e. one element of Codomain.

Hence by vertical line test we can say that the relation given is a function.

The area of the triangle is 4.5 square unit.

We have, y= 4x/ (1 + x³)

Now, differentiating the above equation wrt to x we get

y' = 4(1 + x³)- 4x . 3x² / (1+ x³)²

y'= -8x³ + 4/ (1+x³)²

When x = 1 then y' = -4/4 = -1

so, y -2 = -1 (x-1)

y= -x+ 3

Here the x intercept is (3, 0) and y intercept is (0, 3).

so, Area of Triangle is

Answer:

0.8^4

Step-by-step explanation:

Write the expression using exponents.

\(0.8 \: · \: 0.8 \: · \: 0.8 \: · \: 0.8 \: = \boxed { ? }\)

Since, the expression is actually the repetition of 0.8, so we can write this as,

⇒ 0.8 · 0.8 · 0.8 · 0.8 = ( 0.8 )⁴

Calculating further, We get,

⇒ ( 0.8 )⁴ = \( \sf \frac{8 \times 8 \times 8 \times 8}{10 \times 10 \times 10 \times 10} = \frac{8⁴}{10⁴} \)

⇒ ( 0.8 )⁴ = \( \frac{4096}{10000} \)

Calculating further, We get,

⇒ ( 0.8 )⁴ = 0.4096

∴ 0.8 · 0.8 · 0.8 · 0.8 = ( 0.8 )⁴ = 0.4096

Using probability of independent events, it is found that there is a:

------------------------------------

\(P(A \cap B) = P(A)P(B)\)

One team is favored in its semi-final match by odds of 1.40 to 1.60:

Thus it's probability of winning is:

\(p_1 = \frac{1.6}{1.4 + 1.6} = \frac{1.6}{3.0} = 0.5333\)

Another squad is favored in its contest by odds of 2.30 to 1.70:

Thus it's probability of winning is:

\(p_2 = \frac{2.3}{4} = 0.575\)

The probability of both winning is:

\(p = 0.5333(0.575) = 0.3066\)

0.3066 = 30.66% probability that both teams win their games.

The probability of neither winning is:

\(p = (1 - 0.5333)(1 - 0.575) = 0.1983\)

0.1983 = 19.83% probability that neither favored team wins its game.

At least one is complementary to neither, thus, the probability of at least one is:

\(p = 1 - 0.1983 = 0.8017\)

0.8017 = 80.17% probability that at least one of the favored teams wins its games.

We proved that \(\angle2\cong\angle4\).

Given: \(\angle2\) and \(\angle4\) are vertical.

We have to prove \(\angle2\cong\angle4\)

The \(\cong\) means congruence which means \(\angle2\) and \(\angle4\) both have same size and angle. We have to show that they both have same size or angle to prove them congruence.

As we know that the value of straight line is \(180^{o}\).

From the given figure we can see that

\(\angle1+\angle2=180^{o}\)

\(\angle3+\angle4=180^{o}\)

\(\angle1+\angle4=180^{o}\)

\(\angle2+\angle3=180^{o}\)

To prove the \(\angle2\cong\angle4\) we subtract \(\angle1+\angle2=180^{o}\) and \(\angle1+\angle4=180^{o}\)

\(\angle1+\angle2-(\angle1+\angle4)=180^{o}-180^{o}\)

We first simplify bracket. When we multiply with the subtraction sign then the sign under the bracket will changed.

\(\angle1+\angle2-\angle1-\angle4=0\)

There have \(\angle1\) in addition and subtraction then there only remains

\(\angle2-\angle4=0\)

We can write that notation as

\(\angle2=\angle4\)

Since \(\angle2=\angle4\), that means they both have same angle.

So we proved that \(\angle2\cong\angle4\).
