Answer:

-5

Step-by-step explanation:

The rate of change, also known as slope, would be -5.

Slope can be found with two points and the formula y minus y divided by x minus x or the change of y divided by the change in x.

To identify the slope on the equation is easy since this is slope-intercept form.

y=mx+b

where m is the slope

m in this case is -5, so -5 is your answer

By using the concept of function, it can be calculated that-

a) [tex]\frac{g}{f}(-4) = \frac{4}{31}[/tex]

b) The point [tex]\frac{7}{6}[/tex] is not in the domain of [tex]\frac{g}{f}[/tex]

What is a function?

A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.

There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.

Here,

a) The given functions are -

   g(x) = (x + 6)(x  + 6)

  f(x)= -6x+7

   [tex]\frac{g}{f}(x) = \frac{g(x)}{f(x)} = \frac{(x+6)(x+6)}{-6x+ 7} = \frac{(x+6)^2}{-6x + 7}[/tex]

   [tex]\frac{g}{f}(-4) = \frac{g(-4)}{f(-4)} = \frac{(-4+6)^2}{-6(-4) + 7} = \frac{4}{31}[/tex]

b)  [tex]\frac{g}{f}(x)[/tex] is not defined if -6x + 7 = 0

     [tex]\frac{g}{f}(x)[/tex] is not defined if  [tex]x = \frac{7}{6}[/tex]

      So the point [tex]\frac{7}{6}[/tex] is not in the domain of [tex]\frac{g}{f}[/tex].

The probability that a resident own a cat or a dog is 48%

From the question, we have the following parameters that can be used in our computation:

P(Own a cat) = 70%

P(Own a dog) = 59%

P(Own a cat and a dog) = 42%

The probability a resident own a cat or a dog is then calculated as

Probability a resident own a cat or a dog = P(Own a cat) + P(Own a dog) - P(Own a cat and a dog)  

Substitute the known values in the above equation, so, we have the following representation

Probability a resident own a cat or a dog = 70% + 59% - 42%

Evaluate the sum and the difference

Probability a resident own a cat or a dog = 48%

Hence, the probability is 48%

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

|AC|^2 = |AB|^2 + |BC|^2    

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

Recall the Pythagorean theorem formula:

a² + b² = c²

Given that Kim is standing on the deck, point k, which is 140.75 feet above ground level.

Louise point L, is standing 200ft from the base of the lighthouse directly below Kim’s position.

Thus the distance, in feet, between point K and point L

Replacing by the values we have;

200 ² + 140.75² = KL²

KL² = 59810.56

KL = 244.56

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

A parachutist's rate during a fast drop arrives at 55 meters each second. In your calculations, accept that the meter is equivalent to 3.3 feet.

Convert the speed into feet per second. Then we have

S = 55 x 3.3

S = 181.5 feet per second

The parachutist fall during 15 seconds of free fall will be given as,

D = 181.5 x 15

The ratio of area of squares is 4:81. Therefore, option C is the correct answer.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given that, the ratio of perimeters of a squares is 2:9.

We know that, perimeter of square is 4a, where a is side of a square

Now, 4x/4y =2/9

x/y =2/9

As we know area of square is a², where a is side of a square

So, x²/y² =2²/9²

x²/y² =4/81

The ratio of area of squares is 4:81. Therefore, option C is the correct answer.

using the formula

Sales tax rate = Sales tax percent / 100

When the costs of the two plans are equal, plan A will cost $37.81, whereas plan B will cost $25.65.

To find the number of calls at which the two plans cost the same, we need to set the costs equal to each other and solve for the number of minutes. The cost of plan A is $19 + $0.11 per minute, and the cost of plan B is $0.15 per minute. Setting these equal to each other, we get:

$19 + $0.11 per minute = $0.15 per minute

We can then solve for the number of minutes by dividing both sides by the per-minute cost:

$19 / $0.11 per minute = $0.15 per minute / $0.11 per minute

This simplifies to:

171 minutes = 135 minutes

Therefore, the two plans cost the same at 171 minutes of calling.

To find the cost at this point, we can substitute 171 minutes back into either of the original cost equations:

Plan A: $19 + $0.11 per minute × 171 minutes = $19 + $18.81 = $37.81

Plan B: $0.15 per minute × 171 minutes = $25.65

Thus, the cost when the two plans cost the same is $37.81 for plan A and $25.65 for plan B.

What do you mean by co interior angle?

Co-interior angles, or consecutive interior angles, are two angles on the same side of a transverse line. Co interior angles are interior angles that add up to 180 degrees. This means that the sum of the two interior angles on the same side of the horizontal side are complementary.

7) Given :

∠EFG = 32 degree

∠GFH = 56 degree

∠EFG = ∠EFG + ∠GFH = 32 + 56 = 88 degree

Therefore, ∠EFG = 88 degree

8) DC and AB are parallel to each other.

AE and AB are perpendicular to each other

CG and AB are perpendicular to each other.

9) As AB and CD are parallel to each other therefore , ∠BAC and ∠ACD are cointerior angle and sum of co interior angles is 180 degree.

6x + 6 + 9x - 6 = 180

15x = 180

x = 180/15 = 12

∠ACD = (9x - 6) degree = 9(12) - 6 = 108 - 6 = 102

Answer: The expression a²+4b² can be factored in the following way:

a²+4b² = (a² + 2ab + 2ab + 4b²)

= (a+b)²

In general, the square of a binomial (a+b) can be written as (a+b)² = a² + 2ab + b². This is known as the "square of a sum" formula. In this case, we can apply this formula to the binomial a+b to obtain a² + 2ab + b² = (a+b)². We can then use the fact that the square of a binomial can be written as the square of each term plus twice the product of the two terms. This allows us to write the expression as (a+b)² = a² + 2ab + b² = a² + 2ab + 2ab + 4b² = (a² + 2ab + 2ab + 4b²) = (a²+4b²). Therefore, the fully factored form of a²+4b² is (a+b)².

The probability that the sample's Republican percentage will be higher than 44% is 0.089.

Probability is a metric used to express the possibility or chance that a particular event will occur.

Probabilities can be expressed as fractions from 0 to 1, as well as percentages from 0% to 100%.

To determine the probability of a sample proportion, the normal probability is used as the z-test statistic of one sample proportion.

When the sample size is big, the z-test statistic, a normal test statistic, is employed.

So, the probability will be:

We know that the sample size is n = 488 and the proportion is p = 0.41.

Now, obtain P(p > 0.44) as follows:

[tex]\begin{aligned}& P(\hat{p} > 0.44)=1-P\left(\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n}}} \leq \frac{0.44-p}{\sqrt{\frac{p(1-p)}{n}}}\right) \\& P(\hat{p} > 0.44)=1-P\left(Z \leq \frac{0.44-0.41}{\sqrt{\frac{0.41(1-0.41)}{488}}}\right) \\& P(\hat{p} > 0.44)=1-P(Z \leq 1.347)\end{aligned}[/tex]

Excel function for the p-value:

P(p > 0.44) = 1 - 0.911
