Step-by-step explanation:

(xm, ym) = ((x1+x2)/2, (y1+y2)/2)

(xm, ym ) = midpoint

(x1, y1) and (x2, y2) are the 2 points.

xm = (-3 + -12)/2 = -15/2 = -7.5

ym = (7 + 8)/2 = 15/2 = 7.5

Answer: 30\(\pi \\\) or 94.247

Step-by-step explanation:

Circumference=2\(\pi\)r

2·\(\pi\)·15=30\(\pi\)=94.247

Answer:

94.2in.

Step-by-step explanation:

The formula for circumference is 2radius x π

π≈3.14

So we can say:

30in.x3.14=circumference

30x3.14=94.2

94.2in=circumference

The acutal width of the picnic area by using proportion if the scale used is 3 inches : 2 yards will be 60 yards.

Let the actual width of the picnic area be x yards.

According to the given question.

Laura measured a picnic area near the river and made a scale drawing.

The scale she used was 3 inches : 2 yards.

⇒ The scale is 3 inches : 2 yards

The width of the picnic area in the drawing is 90 inches.

As we know that, a proportion is a fraction of a total amount, and the measures are related using a rule of three.

Thereofore, the acutal width of the picnic area by using proportion if the scale used is 3 inches : 2 yards is given by

3inches : 2 yards = 90inches : x

⇒ 3x = 180

⇒ x = 60yards

The domain of the function f(x) = (2x^2)/(x + 3) is all real numbers except x = -3, and there are no vertical or horizontal asymptotes.

To find the domain of the function f(x) = (2x^2)/(x + 3), we need to consider any restrictions that could make the function undefined.

First, we note that the function will be undefined when the denominator, x + 3, equals zero, as division by zero is undefined. Therefore, we set x + 3 = 0 and solve for x:

x + 3 = 0

x = -3

So, x = -3 is the value that makes the function undefined. Therefore, the domain of the function is all real numbers except x = -3.

Domain: All real numbers except x = -3.

Next, let's identify any vertical and horizontal asymptotes of the function.

Vertical Asymptote:

A vertical asymptote occurs when the function approaches positive or negative infinity as x approaches a particular value. In this case, since the degree of the numerator (2x^2) is greater than the degree of the denominator (x + 3), there will be no vertical asymptote.

Vertical asymptote: None

Horizontal Asymptote:

To find the horizontal asymptote, we examine the behavior of the function as x approaches positive or negative infinity. We compare the degrees of the numerator and denominator.

The degree of the numerator is 2 (highest power of x), and the degree of the denominator is 1. Since the degree of the numerator is greater, there is no horizontal asymptote.

Horizontal asymptote: None

In summary:

Domain: All real numbers except x = -3

Vertical asymptote: None

Horizontal asymptote: None

Transformation involves changing the coordinates of a point

The coordinates of the image of P is (9,13)

The coordinate of P is given as:

P = (-13,9)

The rule of reflecting the point over the line y = -x is represented as:

\((x,y) \to (y,-x)\)

So, we have:

\((-13,9) \to (9,13)\)

This means that:

\(P' = (9,13)\)

Hence, the coordinates of the image of P is (9,13)

Answer:

Step-by-step explosion:

The possible measurements for the diameter of the bin are 10 feet, 15 feet, and 18 feet. The correct answers are (A) (B) and (C).

We can start by finding the equation of the line representing the side of the warehouse that is closest to the circular storage bin. This line goes through the points (39,20) and (39,50), so its equation is x=39.

To ensure that the storage bin is at least 2 feet away from the warehouse, we need to make sure that its center is at least 2 feet away from the line x=39. The center of the bin is at (50,40), which is 11 feet away from the line x=39. Therefore, the radius of the bin needs to be at most 11-2=9 feet.

The diameter of the bin is twice the radius, so any diameter that is at most 18 feet will work. Therefore, the possible measurements for the diameter of the bin are 10 feet, 15 feet, and 18 feet. Thus, the correct answers are (A) 10 feet, (B) 15 feet, and (C) 18 feet.

Therefore, the state government should consider investing in new affordable housing initiatives.

a) To compute the 90% confidence interval, we can use the formula:

CI = p ± z*(√(p(1-p))/n)

where p is the sample proportion, z is the z-score corresponding to a 90% confidence level (which is 1.645), and n is the sample size.

Plugging in the values, we get:

CI = 0.517 ± 1.645*(√((0.517)(1-0.517))/4527)

CI = 0.505 to 0.529 (rounded to three decimal places)

b) The 90% confidence interval tells us that we are 90% confident that the true proportion of Californians who considered moving out of the state is between 0.505 and 0.529.

c) Since the confidence interval does not include the value of 0.5, which is the null hypothesis value, we can conclude that there is evidence to suggest that more than 50% of Californians would consider moving out of state due to high cost of housing.

w + w + 1 = w + 33

Solution

2w + 1 = w + 33      Subtract w from both sides.

2w - w + 1 = 33       Combine

w + 1 = 33               Subtract 1 from both sides.

If z varies with y and inversely with and z = 6 when x = 4 and y = 3, then the value of Proportionality Constant is given by 8.

Proportion is a relation between two mathematical variables. If two variables vary directly that states if one increases another will also decrease and same for decrease.

If two variables are in inverse relation that states that if one variable increases then another decreases and if one variable decreases then another increases.  

Given that, z varies with y and inversely with x. So,

z = k*(y/x), where k is the proportionality constant.

Given that, z = 6 when x = 4 and y = 3. So,

6 = k*(3/4)

k = (6*4)/3

k = 2*4

k = 8
