The inner product of vectors (8,4) and (2,4) is 32, and since the dot product is not zero, the vectors are not perpendicular.
The inner product (also known as the dot product) of two vectors can be calculated by multiplying the corresponding components of the vectors and then summing those products. For the vectors (8,4) and (2,4), the inner product is calculated as (8 × 2) + (4 × 4), which equals 16 + 16, and thus the inner product is 32.
To determine if the vectors are perpendicular, we need to check if their dot product is zero. In this case, since the dot product is 32, not zero, the vectors are not perpendicular to each other.
Therefore, the correct answer is C: 32; no.

For each inequality, write all one-digit integers that satisfy it.
k>0
Final answer:
To find all one-digit integers satisfying the inequality k > 0, we list every positive one-digit integer from 1 to 9, as these are the numbers that are greater than zero and meet the conditions of the inequality.
Explanation:
The question asks to identify all one-digit integers that satisfy the inequality k > 0. This inequality means that k must be greater than 0. Since we are only considering one-digit integers, we need to list all the numbers from 1 to 9, as these are the positive one-digit integers.
1
2
3
4
5
6
7
8
9
Each of these numbers is greater than 0 and thus satisfies the inequality k > 0. Numbers that are zero or negative do not meet the requirement of the inequality.

Answer:
Your answer is correct. (x-4)^2 = 3
Step-by-step explanation:
x^2 - 8x + 13 (is not a perfect square so you need to move the 13 to the right by subtraction)
x^2 - 8x + ____ = -13 (In order to get A, divide the second coefficient by 2. That would be -4 in this case. Now we need to square A to find the constant. That would be 16)
(x^2 - 8x + 16) = -13 + 16 (Whatever we do on the left we add on the right, -13+16 = 3)
(x-4)^2 = 3

Your sister helped you get a dream job at a designer clothing store and one of the perks of the job is that you get 15% off all clothing that you buy at their store. During your first month of employment you purchased $235 tax-free (before the discount) worth of clothing from the designer store. You worked 25 hours during that month at $9.50 an hour and they deducted 15% of your total paycheck for deductions. Did you still make money in your first month of employment regardless of how much you spent at their store for designer clothes? How much? Show your work.
Answer:
$197.30 revenue.
Step-by-step explanation:
As long as we realise that 15% = $237.50 total revenue - 15% of that revenue $40.20 and the other 15% was totaled prior and kept to one side as seen as expenditure.
revenue = r clothing purchase = p
r = (25 x 10 -12.50) - (p15% of e235)
r = (250 - 12.50) -( e235- p23.5 +11.73)
r = (237.50) - (expenditure 235- p35.73)
r = 237.50 -(expenditure 199.27)
r= 237.50
e = 199.27
p = 35.73
Answer with out including expenditure your sister revenue was $237.50
The 15% deduction cannot be confused with the deduction from clothes.
If we were to calculate 15% of $237.50 this would be 23.7+ 16.85 =$40.2
A different Salary related 15% contribution payments = $40.20
If these were taken from $237.50
Then $237.50- $40.20 = $197.30 revenue, but we do not have to show expenditure in the total only the workings, which is still owed being $199.27- $40.20 already paid towards.
Extension = This means because $40.20 was deducted then expenditure still to be deducted outside of the question would be e. $199.27 - $40.20 = 159.07 still owed. Saying that the 15% was to pay your sisters contribution to the clothes and not to the state.
Solve: 12^2 + 4x = 0
Answer:
Step-by-step explanation:
12² + 4x = 0
144 + 4x = 0
subtract 144 from both sides
144 + 4x - 144 = 0 - 144
4x = -144

During his career, Walter Payton rushed for 16,726 yards. How many feet is that? I WILL GIVE BRAINLIEST!!!!!!!!
Step-by-step explanation:
1 yard = 3 feet so we will multiply 16726 yards with 3 so answer = 16726 × 3 = 50178
Final answer:
To convert yards to feet, multiply the number of yards by 3. Walter Payton rushed for 16,726 yards, which equals 50,178 feet when converted.
Explanation:
The question asks to convert the number of yards rushed by Walter Payton during his career into feet. To find the conversion, you can use the fact that there are 3 feet in 1 yard. Therefore, to convert yards to feet, you should multiply the number of yards by 3.
Walter Payton rushed for 16,726 yards during his career. Using the conversion factor:
Feet = Yards × 3So,
Feet = 16,726 yards × 3
Feet = 50,178 feet
Thus, Walter Payton rushed for 50,178 feet during his career.
A zookeeper created the following stem-and-leaf plot showing the number of tigers at each major zoo in the country:
Answer:

A stem-and-leaf plot is a tool used in mathematics to organize and interpret data. In this case, it's used to understand the distribution of tigers in major zoos across the country and can help find modes, medians, ranges for the dataset.
Explanation:The question refers to a stem-and-leaf plot, a graphical tool widely used in mathematics for organizing and interpreting data. It's often used in middle school to introduce students to basics of statistics. In the context of this specific problem, the 'stems' would represent the tens place of the number of tigers and the 'leaves' would represent the ones place.
For example, a stem of 2 and a leaf of 3 would represent 23 tigers. When compiled, this plot provides an overview of the distribution of tigers in major zoos across the country. This type of graph is extensively useful for finding modes, medians, and ranges for data sets.

6. A cone has a diameter of 6 inches and a height of 8 inches. Find the
volume using 3.14 for Tr. *
Final answer:
To calculate the volume of a cone with a diameter of 6 inches and a height of 8 inches, use the radius which is 3 inches and apply the formula V = 1/3πr²h, resulting in a volume of 226.08 cubic inches.
Explanation:
The subject's question is about finding the volume of a cone with a given diameter and height. The formula to calculate the volume of a cone is V = ⅓πr²h. Given that the diameter is 6 inches, the radius (r) is half of that, which is 3 inches. Using 3.14 for π (pi), and the given height (h) of 8 inches, we can substitute these values into the formula to find the volume.
So, the calculation is:
Find the radius (r) by dividing the diameter by 2, r = 3 inches.
Substitute r and h into the volume formula: V = ⅓πr²h = ⅓(3.14)(3 inches)²(8 inches).
Calculate the square of the radius (3 inches)² = 9 inches².
Multiply the area with height and π: V = ⅓(3.14)(9 inches²)(8 inches) = 226.08 cubic inches.
Therefore, the volume of the cone is 226.08 cubic inches.
