What is completing square method?Write the equation in the form, such that c is on the right side.
Step 2: If a is not equal to 1, divide the complete equation by a such that the coefficient of x2 will be 1.
Step 3: Now add the square of half of the coefficient of term-x, (b/2a)2, on both sides.
Given equation:
x² - 4x - 32 = 0
Now, add and subtract (2)² we get
x² - 4x - 32 + 2² - 2² = 0
x² - 4x + 2² - 32 - 2² = 0
(x-2)² -36=0

A tree casts a shadow that is 24 feet long. Brad is 5 feet tall, and while standing near the tree he casts a shadow that is 4 feet long. How tall is the tree?
Answer:
30 ft
Step-by-step explanation:
brad is 5 ft tall and has a shadow of 4 ft when standing by the near the trees shadow is 24 ft
so 24 ft / 4 ft =6 ft
so the tree is 6 times bigger than brad so you would multiple brads hight by 6
so that would be 5 times6 =30 ft
thus the tree is 30 ft tall
The shadow height of the tree is 24 feet, then the height of the tree will be equal to 30 feet.

Jody has four bottles of soft drink – one bottle of cola, one of root beer, one of ginger ale, and one of orange. She chooses three of these bottles to take to a party. If she chooses the ginger ale, what is the probability she also chooses root beer?
If Jody chooses the ginger ale, the probability that she also chooses root beer from her selection is 1/3.
Explanation:Jody has four bottles of soft drink: one bottle of cola, one of root beer, one of ginger ale, and one of orange. She chooses three of these bottles to take to a party. The question is, if she chooses the ginger ale, what is the probability she also chooses root beer?
Since Jody has already chosen the ginger ale, she now has to choose 2 more bottles from the remaining three (cola, root beer, and orange).
There are 3 choose 2 ways (which is 3 ways) for Jody to pick her remaining bottles.
Only one of these combinations includes root beer (ginger ale, root beer, and one of the others).
Therefore, the probability that she also chooses root beer, given she has chosen ginger ale, is 1/3.

A semicircular driveway has a diameter of 70 ft. How long is the driveway?
Answer:
109.9
Step-by-step explanation:
It is asking for circumfrence right?
c=pi(d)
c=1/2(3.14)(70)
c=109.9
Sorrry if i am wrong
To find the length of the semicircular driveway with a diameter of 70 ft, calculate the circumference using the formula C = π * diameter.
To find the length of the driveway:
Given the diameter is 70 ft, the radius is half of that, which is 35 ft.
The formula for the circumference of a circle is C = π * diameter.
Substitute the values to find the length, C = 3.14 * 70 ft = 219.8 ft.
The area of a triangle is 15 square centimeters. If all the dimensions of the triangle are multiplied by 5, what will be the area of the new figure?
please help :)
75 cm2 150 cm2 375 cm2 625 cm2
Answer:
375 cm2
Step-by-step explanation:
The new area of the triangle will be 187.5 square centimeters.
Explanation:To find the area of a triangle, you can use the formula A = ½ x base x height. Given that the area of the triangle is 15 square centimeters, we can set up the equation as 15 = ½ x base x height. We are told that all the dimensions of the triangle are multiplied by 5, so the new base and height will be 5 times the original dimensions. Substituting these values into the equation, we get 15 = ½ x (5 x base) x (5 x height). Simplifying the equation, we have 15 = 12.5 x base x height.
Therefore, the new area of the triangle is 12.5 times the original area, which is 15 x 12.5 = 187.5 square centimeters.
The company A produces products a, and the company B produces products b. It is known that 3 percent of companies that produce products a go bankrupt over the year. Plus, the probability for companies producing products b to go bankrupt over the year is 6.1. What is the probability (given in decimal number) that both companies are going bankrupt over the year?
Answer:
0.00183
Step-by-step explanation:
The two companies produce different products and the chance to go bankrupt will be different based on the product made. So, the probability of the company A and B to go bankrupt is independent.
To find the answer of this question, we just need to multiply the probability to go bankrupt of each company. The calculation will be:
P(A=bankrupt) * P(B=bankrupt)= 3% * 6.1% =0.183%= 0.00183
What is the image point of (9,5)(9,5) after a translation right 4 units and up 4 units?
Answer:

Step-by-step explanation:
I hope this helps and I hope I can get Brainliest! =)
Final answer:
The image point of the original point (9,5) after a translation right 4 units and up 4 units is (13,9).
Explanation:
The student is asking about the result of a translation transformation in a two-dimensional coordinate system. Specifically, the student wants to know the new coordinates of a point after it is moved 4 units to the right and 4 units up. The original coordinates are given as (9,5). To find the image point after the translation, we simply add the corresponding values to each coordinate. So, we add 4 to the x-coordinate (9+4) and 4 to the y-coordinate (5+4).
The new coordinates, or the image point, will be:
x-coordinate: 9 + 4 = 13
y-coordinate: 5 + 4 = 9
Therefore, the image point after the translation is (13,9).

What is the equation for a line that passes through the points (2,0) and (-4,9)?
Answer:
y = -3/2x+3
Step-by-step explanation:
We first need to find the slope using
m = (y2-y1)/(x2-x1)
= (9-0)/(-4 -2)
9/-6
=-3/2
We will use the slope intercept form of the equation
y = mx+b where m is the slope and b is the y intercept
y = -3/2x+b
Substitute a point into the equation
0 = -3/2(2) +b
0 = -3+b
b = 3
y = -3/2x+3

pay of $474 and is certain the amount is incorrect
ist
Answer:
(a)Bill's Total piecework pay =$500
(b)Amount owed by his boss=$26
Step-by-step explanation:
Let the number of documents put together and prepared for mailing by Bill =x
Bill receives 25 Cents=$0.25 for every document
Therefore for x documents, Bill should receive: $0.25x
If Bill prepared 2000 documents for mailing
x=2000
The amount he should receive = $0.25 X 2000 =$500
(a)Bill's Total piecework pay =$500
(b)Amount owed by his boss
=500-474
=$26
Bill should have received a gross pay of $500 for preparing 2,000 documents.
Explanation:Bill works for the Stuff It Mailing Service and receives 25 cents for each document he prepares for mailing. Last week, Bill prepared 2,000 documents for a local department store. To find his correct gross pay, we can multiply the number of documents he prepared by the amount he earns per document: 2,000 documents × $0.25 per document = $500. Therefore, the correct gross pay for Bill should be $500.

Shreya made the following table where she categorized countries by their region and by average business startup costs, as a percentage of the per capita gross national income (GNI) for a certain year. She decided that high meant greater than or equal to 8% but less than 70%t of the GNI and that very high meant greater than or equal to 70% of the GNI
Find the probability that the country is in the south Asia region, given that Shreya categorized the country's business startup costs as high.
P(south Asia ∣ high)=
Answer:7/87
Step-by-step explanation:
To find the probability that a country is in the South Asia region given that Shreya categorized the country's business startup costs as high, we can use conditional probability. This involves finding the intersection of the two events and dividing it by the probability of one of the events. In this case, we need the specific numbers to calculate the actual probabilities.
Explanation:To find the probability that a country is in the South Asia region given that Shreya categorized the country's business startup costs as high, we need to use conditional probability. Let's assume that event A is the country being in the South Asia region and event B is the country's business startup costs being categorized as high. We can use the formula:
P(A|B) = P(A ∩ B) / P(B)
In this case, P(A ∩ B) is the probability that the country is in the South Asia region and its business startup costs are categorized as high. P(A ∩ B) refers to the intersection of A and B, meaning the countries that fall into both categories. P(B) is the probability that the business startup costs are categorized as high, which is given as part of the question.
Since we don't have the numbers needed to calculate the actual probabilities, I'll provide an example for better understanding. Let's say there are 10 countries in total, and 3 of them are in the South Asia region. Out of these 3 countries, 2 have high business startup costs. So in this case, P(A ∩ B) = 2/10 and P(B) = 6/10. Plugging these values into the formula, we have:
P(A|B) = (2/10) / (6/10) = 2/6 = 1/3
Therefore, the probability that a country is in the South Asia region given that Shreya categorized the country's business startup costs as high is 1/3.
