maybe this ?

Answer:

9) no solution

10) p = 4

11) n = 2

12) x = 3

Step-by-step explanation:

9) -5 ( -v - 4) + 4v = v + 20

5v + 20 + 4v = v + 20

no solution

10) -2 -3(p + 3) = -4p - 7

-2 - 3p - 9 = -4p - 7

-11 = -1p - 7

-4 = -1p

p = 4

11) 4(3 - 4n) = -24 + 2n

12 - 16n = -24 + 2n

-18n = -36

n = 2

12) 4(4 - 3x) = -23 + x

16 - 12x = -23 + x

-13x = -39

x = 3

hope this helps! :)

Answer:

Number 11 Answer = n = 2 || Number 12 Answer = x = 3

Step-by-step explanation:

12) 4(4 - 3x) = -23 + x

1. multiply 4 times 4 and 4 times 3x

16 - 12x = -23 + x

2. subtract 16 from itself 16 and 23

-12x = -39 + x

3. subtract x from itself and -12x

-13x = -39

4. Divide -13 from itself and -39

x = 3

11) 4(3 - 4n) = -24 + 2n

1. multiply 4 times 3 and 4 times 4n

12 - 16n = -24 + 2n

2. subtract 12 from itself and 24

-16n = -36 + 2n

3. subtract 2n from itself and -16n

-18n = -36

4. Divide -18n from itself and -36

n = 2

The additive inverse of the expression -3/w is 3/w.

A number is known as the additive inverse of another, if the sum of the two numbers comes out to be zero. For example- given a number 3, its additive inverse will be -3, as 3 + (-3) = 0. The additive inverse of 0 is 0 itself.

Here, we are given an expression -3/w, such that w ≠ 0

Let us assume that the additive inverse of -3/w is x

Then, the sum of -3/w and x must be equal to zero

⇒ -3/w + x = 0

adding 3/w to both sides

⇒ x = 3/w

Thus, the additive inverse of -3/w is 3/w.

The statement is false. When an economy shrinks at a constant annual rate, the cumulative decline over multiple years is not simply the sum of the annual rates of decline.

To calculate the cumulative decline over the four-year period, we need to use the concept of compound growth/decline.

If the economy shrinks at a rate of 10% per year for four consecutive years, the actual cumulative decline can be calculated as follows:

Cumulative decline = (1 - Rate of decline) ^ Number of years

In this case, the rate of decline is 10% or 0.1, and the number of years is 4.

Cumulative decline = (1 - 0.1) ^ 4

Cumulative decline = 0.9 ^ 4

Cumulative decline = 0.6561

So, the economy would actually shrink by approximately 65.61% over the four-year period, not 40%.

To find the union and intersection of the intervals I₁ = (-2, 2] and I₂ = [1, 5), let’s consider the overlapping values and the combined range.

The union of two intervals includes all the values that belong to either interval. Taking the union of I₁ and I₂, we have:

I₁ U I₂ = (-2, 2] U [1, 5)

To find the union, we combine the intervals while considering their overlapping points:

I₁ U I₂ = (-2, 2] U [1, 5)
= (-2, 2] U [1, 5)

So the union of the intervals I₁ and I₂ is (-2, 2] U [1, 5).

Now let’s find the intersection of the intervals I₁ and I₂, which includes the values that are common to both intervals:

I₁ ∩ I₂ = (-2, 2] ∩ [1, 5)

To find the intersection, we consider the overlapping range between the two intervals:

I₁ ∩ I₂ = [1, 2]

Therefore, the intersection of the intervals I₁ and I₂ is [1, 2].

Answer:

Mr. A initially paid approximately N8000 for the land.

Step-by-step explanation:

Step 1: Let's assume Mr. A initially purchased the land for a certain amount, which we'll call "x" in currency units.

Step 2: Mr. A sold the land to Mr. B at a profit of 10%. This means Mr. A sold the land for 110% of the amount he paid (1 + 10/100 = 1.10). Therefore, Mr. A received 1.10x currency units from Mr. B.

Step 3: Mr. B sold the land to Mr. C at a gain of 5%. This means Mr. B sold the land for 105% of the amount he paid (1 + 5/100 = 1.05). Therefore, Mr. B received 1.05 * (1.10x) currency units from Mr. C.

Step 4: According to the given information, Mr. C paid N1240 more for the land than Mr. A paid. This means the difference between what Mr. C paid and what Mr. A paid is N1240. So we have the equation: 1.05 * (1.10x) - x = N1240

Step 5: Simplifying the equation: 1.155x - x = N1240

Step 6: Solving for x: 0.155x = N1240

x = N1240 / 0.155

x ≈ N8000

Therefore, in conclusion, Mr. A initially paid approximately N8000 for the land.

Answer:

k=16

Step-by-step explanation:

So the tangent line is

\(4x + k\)

and it tangent to function

\( {x}^{2} + 8x + 20\)

Since the slope of the tangent line is 4, this means the derivative of f(x) is 4 but first let find the derivative of

\( {x}^{2} + 8x + 20\)

Use the Sum Rule,

\( \frac{d}{dx} {x}^{2} + \frac{d}{dx} 8x + \frac{d}{dx} 20\)

Use the Power Rule and we get

\(2x + 8\)

Set this equal to 4

\(2x + 8 = 4\)

\(2x = - 4\)

\(x = - 2\)

So at x=-2, the slope of the tangent line is 4.

Plug -2 in the orginal function, and we get

\( { - 2}^{2} + 8( - 2) + 20 = 8\)

So the point must pass through -2,8 with a slope of 4.

\(y - 8 = 4(x + 2)\)

\(y - 8 = 4x + 8\)

\(y = 4x + 16\)

So the value of k is 16.

The Chi-square test is a statistical test used to determine if there is a significant difference between observed and expected frequencies in categorical data. In this example, the test is used to assess whether there is a significant difference in the mean breaking strengths of two types of cables.

The Chi-square test of significance is employed when dealing with categorical or nominal data. It compares the observed frequencies with the frequencies that would be expected if the variables were independent. In this case, the breaking strengths of the two cables are the variables of interest.

To perform the test, the first step is to define the null hypothesis (H0) and the alternative hypothesis (Ha). In this example, H0 assumes that there is no difference in the mean breaking strengths of the two cables, while Ha suggests that there is a difference.

Next, the test statistic, denoted by X2 (chi-square), is calculated using the formula X2 = Σ[(O - E)²/E], where O represents the observed frequencies and E represents the expected frequencies under the assumption of independence.

To determine the expected frequencies, we need to estimate the means and variances of the breaking strengths. Here, x = 1925 and sigma = 40 for the first cable, and x = 1905 and sigma = 30 for the second cable.

Once the test statistic is calculated, it is compared to a critical value from the Chi-square distribution with degrees of freedom equal to (r - 1)(c - 1), where r is the number of rows and c is the number of columns in the contingency table. The significance level of 0.01 determines the critical value.

If the calculated X2 value is greater than the critical value, we reject the null hypothesis and conclude that there is sufficient evidence to indicate a difference in the mean breaking strengths of the two cables. Conversely, if the calculated X2 value is less than or equal to the critical value, we fail to reject the null hypothesis and conclude that there is no significant difference.

A ratio is an ordered pair of numbers a and b written  as:

a / b where b does not equal 0.

A proportion is an equation in which two ratios are equal to each other.

We have,

The ratio of men to women:

= 5:7

= 5/7

Let,

The number of men = 5x

The number of women = 7x

Now,

If the number of women = 595

We have,

7x = 595

Multiplying both sides by 5/7 we get,

5/7 x (7x) = 5/7 x 595

5x = 5/7 x 595

5x = 5 x 85

5x = 425

This means if there are 435 men in the social club if the number of women is 595.

Thus if the number of women in the social club is 595 then the number of men in the social club is 425.

The measure of angle 4 is 90 degrees.

When two parallel lines are cut by a transversal, the corresponding angles formed are congruent. In this case, angle 4 is formed by the intersection of transversal f and line b. Since lines a and b are parallel, angle 4 is a corresponding angle to angle 1, which is formed by the intersection of transversal f and line a.

Since angle 1 is a right angle, measuring 90 degrees, it follows that angle 4, being the corresponding angle, will also measure 90 degrees. Therefore, the measure of angle 4 is 90 degrees.

True, the eventual success of any system solely depends on how users work with it.

A system's success is determined by various factors, such as its design, functionality, and compatibility with user needs.

However, user engagement, adaptability, and willingness to work with the system notably contribute to its success.

Users who understand the system's features and can efficiently adapt and utilize them in their workflow contribute to its overall effectiveness.

In contrast, a system with poor user adoption and engagement may not achieve its intended outcomes, regardless of its inherent quality.

So, even if a system is well-designed and has all the necessary features, if users are unable to effectively use it, the system will not achieve its intended purpose.

The radioactive substance remaining after 43 hours is: 62.7273 mg by unitary method.

A single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary method.

Now,

Given that 180 mg is present at t = 0 hours.

After t = 33 hours, substance left = 90mg

By unitary method, after = 1 hour, substance left = \(180-\frac{90}{33}=180 -\frac{30}{11}\)mg

The substance left after t = 43 hours = \(180 - \frac{30\times43}{11}= 180 - \frac{1290}{11}=180 - 117=62.7273mg\)

The statement is true. In the context of vector calculus, the dot product between two vectors u and v is defined as the product of their magnitudes and the cosine of the angle between them.

The dot product satisfies the distributive property and is linear with respect to scalar multiplication, which means that for any scalar c and vectors u and v, we have:

u · (cv) = c(u · v)

This equation states that taking the dot product between vector u and the scalar multiple cv is equivalent to multiplying u by the dot product between u and v scaled by c.

This property is useful in many applications of vector calculus, including the computation of work and the projection of vectors onto subspaces. It is also used in the definition of the norm and the inner product of vectors.
