Answer:
~20.6155
Step-by-step explanation:
To compute distance between two points, we can get the vector from one to the other by subtracting them and then computing the length of the vector.
The length of a vector V is:
[tex]|V| = \sqrt{\sum_{i=1}^n v_i^2}\\[/tex]
The vector is:
(9, -5. 4) - (-10, 3, 4) = (9 + 10, -5 - 3, 4 - 4) = (19, -8, 0)
So the length is:
[tex]\sqrt{19^2 + (-8)^2} = \sqrt{361 + 64} = \sqrt{425} = \sqrt{5\cdot 5\cdot 17} = 5\sqrt{17} \approx 20.6155281281[/tex]

Red pyramid volume: 59300000 feet³
Pyramid of Khafre volume: 74400000 feet³
Subtract to get difference
74400000-59300000= 15100000
Nearest in answer choice is 15,180,495 so therefore it is the third choice.
You charge $2 per evening plus $5 per hour to babysit and you only charge for whole hours. You have a goal to earn at least $121 for 8 evenings of babysitting. What is the least amount of hours in total you need to babysit for the evenings?
Answer:
8 hours
Step-by-step explanation:
Answer:
21 hours
Step-by-step explanation:
8 evenings x $2 per evening = $16
$121 - $16 = $105
$105 / $5 per hour = 21 hours
to check:
21 hours x $5 per hour = $105
8 evenings x $2 per evening = $16
$105 + $16 = $121
what is a discriminant? (maths definition)
Discriminant: in mathematics, a parameter of an object or system calculated as an aid to its classification or solution.
Answer: Discriminant, in mathematics, a parameter of an object or system calculated as an aid to its classification or solution. In the case of a quadratic equation ax2 + bx + c = 0, the discriminant is b2 − 4ac; for a cubic equation x3 + ax2 + bx + c = 0, the discriminant is a2b2 + 18abc − 4b3 − 4a3c − 27c2

What is the distance between (8, -3) and (4, -7)?
Choose 1 answer
Answer:
Option C √32 is correct
Step-by-step explanation:
Here,
x₁ = 8
x₂ = 4
y₁ = (-3)
y₂ = (-7)
Now,
By Using Distance Formula
D = √(x₂ - x₁)² + (y₂ - y₁)²
= √(4 - 8)² + [(-7) - (-3)]²
= √(-4)² + [(-7) + 3]²
= √16 + (-4)²
= √16 + 16
D = √32
Thus, The distance between (8, -3) and (4, -7) is √32

15 tractors each working 8 hours a day take to take eight days to Plough a piece of land how many days will it take 24 tractors each working 10 hours a day to plough the same piece of land
It will take 24 tractors, each working 10 hours a day, a total of 4 days to plough the same piece of land.
To determine how many days it will take 24 tractors, each working 10 hours a day, to plough the same piece of land, we can use the concept of man-hours.
Given that 15 tractors, each working 8 hours a day, took 8 days to complete the task, we can calculate the total man-hours required to plough the land.
Total man-hours = Number of tractors * Hours per tractor * Number of days
Total man-hours = 15 tractors * 8 hours/tractor * 8 days
Total man-hours = 960
Now, let's calculate the number of days required for 24 tractors, each working 10 hours a day, to complete the task.
Number of days = Total man-hours / (Number of tractors * Hours per tractor)
Number of days = 960 / (24 tractors * 10 hours/tractor)
Number of days = 960 / (240)
Number of days = 4
As a result, ploughing the same plot of land will require 24 tractors to labour for a total of 4 days at 10 hours per day each.

Allie identifies the coordinates of point D as (3, 7). Explain her error and explain how to correctly identify the ordered pair.
Answer:
[tex]D = (7,3)[/tex]
Step-by-step explanation:
Given
[tex]D = (3,7)[/tex]
See attachment for graph
Required
Identify and correct the error
From the attached graph, the coordinate of D is at:
[tex]x = 7[/tex]
[tex]y = 3[/tex]
So:
Allie's mistake is that, she identifies x as y coordinate and y as the x coordinate.
So, the right coordinate is:

His pay gets income tax deducted at a rate of 18% = 18/100
That means you multiply is weekly wage by 18/100 to get what the government takes off.
Solution
18/100 * 495 = 80.10
The government takes $80.10
His take home pay is 495 - 80.10 = $405.90
Note:
There is a short way of doing his take home pay if that is all you are interested in. His take home pay is 82% of his gross pay which is 82/100 * 495.
82/100 * 495 = 405.90
