Need help with this maths vector question
Answer:
Step-by-step explanation:
(a) We can find the position vectors of the points L, M, and N by taking the average of the position vectors of the points they lie between.
The midpoint of AB is given by:
N = (A + B)/2 = (41 + (41 + 21))/2 = (41 + 62)/2 = 51.5i
The midpoint of AD is given by:
L = (A + D)/2 = (41 + 6k)/2 = 23i + 3k
The midpoint of BD is given by:
M = (B + D)/2 = (41 + 21 + 6k)/2 = 31i + 3.5k
Now, we can find the vector MN by subtracting the position vectors of M and N:
MN = M - N = (31i + 3.5k) - (51.5i) = -20.5i + 3.5k
The angle between the directions of MN and OB can be found using the dot product:
cos(θ) = (MN . OB) / (|MN| * |OB|)
where θ is the angle between the two vectors. We can find the dot product and the magnitudes of the vectors as follows:
MN . OB = -20.5i + 3.5k . 41i + 21j = -20.5 * 41 + 3.5 * 21 = -847.5
|MN| = √((-20.5)^2 + (3.5)^2) = 21
|OB| = √(41^2 + 21^2) = √(1764) = 42
Substituting these values into the formula for cos(θ), we get:
cos(θ) = (-847.5) / (21 * 42) = -0.5
The angle θ can be found from the cosine inverse:
θ = cos^-1(-0.5) = 120 degrees
So, the angle between the directions of MN and OB is 120 degrees.
(b) To find the value of p, we can use the intersection of the lines through P and B and the lines through C and L. Let's call the intersection point R.
The line through P and B can be represented as P + t(B - P) = R
where t is a scalar and R is the position vector of the intersection point. Similarly, the line through C and L can be represented as:
C + s(L - C) = R
where s is a scalar. Setting these two expressions equal to each other, we get:
P + t(B - P) = C + s(L - C)
Expanding and simplifying, we get:
P + t(41i + 21j + 6k) = 21i + 6s(23i + 3k)
Comparing the i, j, and k components, we get:
P + 41t = 21 + 6s * 23
t = (21 - P)/41
6s = (P - 21)/23
s = (P - 21)/138
Substituting s back into the equation for C + s(L - C), we get:
C + (P - 21)/138 * (L - C) = R
21i + 6k + (P - 21)/138 * (23i + 3k - 6k) = R
Expanding, we get:
21i + 6k + (23/138) * Pi + (3/138) * k = R
Comparing the i and k components, we get:
21 + (23/138) * P = Ri
6 + (3/138) * P = Rk
Solving for P, we get:
P = 138 * (Ri - 21)/23 = 138 * (Rk - 6)/3
So the value of p for which the line through P and B intersects the line through C and L is given by the above formula.
When hired at a new job selling jewelry, you are given two pay options:
Option A: Base salary of $17,000 a year, with a commission of 8% of your sales
Option B: Base salary of $24,000 a year, with a commission of 4% of your sales
In order for option A to produce a larger income, you would need sell at least $
of jewelry each year.
Answer:
$175,000
Step-by-step explanation:
We can use a system of inequalities to solve this problem
Let X be the sales of jewelry in $
Option A
Base salary = $17,000
Commission: 8% of sales
Commission at 8% =8% x $X = 8/100 x $X = $0.08X
Total remuneration = 17,000 + 0.08X
Option B
Base salary = $24,000
Sales = X$
Commission = 4% of $X = 4/100 x $X = $0.04X
Total remuneration = 24,000 + 0.04X
For Option A to be a better deal(higher income)
Total remuneration on Option A > Total remuneration on Option B
17,000 + 0.08X ≥ 24,000 + 0.04X
(we are using ≥ symbol though the question does state larger income, later on it states at least how many $ worth of sales)
Subtract 0.04X from both sides:
17,000 + 0.08X - 0.04X >= 24,000 + 0.04X -0.04X
17,000 + 0.04X >= 24,000
Subtract 17,000 both sides:
17,000 - 17,000 + 0.04X ≥ 24,000 - 17,000
0.04X ≥ 7,000
X ≥7000/0.04
X ≥ $175,000
So under Option A, you would need to sell at least $175,000 worth of jewelry to make a larger income.
Actually at $175,000 the income from both options are equal

T (ABCD) = (A'B'C'D'). If A is (6, −8), A' is (−2, 4), and B is (4, −6), what are the coordinates of B'?
A. (−4, −12)
B. (−8, −4)
C. (−4, 6)
D. (−2, −12)
Option C : (-4, 6) are the coordinates of B'.
What are meant by coordinates?
Coordinates are two integers (Cartesian coordinates) or often a letter and a number that identify a particular place on a grid known as a coordinate plane. A coordinate plane has four quadrants and two axes: the horizontal x-axis and the vertical y-axis (vertical).
Given T(ABCD) = (A'B'C'D') and A = (6, -8) , A' = (-2, 4)
If B = (4, -6) then let B' = (x, y)
now, x - 4 = -2 - 6
x = 4 - 2 - 6 = -4
and y - (-6) = 4 - (-8)
y + 6 = 4 + 8
y = 6
Therefore, B' = (-4, 6)

How many cans of a nutritional supplement as a patient in just over seven days if each can contains 12 Ozzie in the mountain just per day is 1080 milliliters is vegan
Answer:
Second Option : 21
Step-by-step explanation:
At 1080 ml per day for 7 days, the patient would have to ingest 1080 x 7 = 7,560 ml
Since the can capacity is given in oz we have to convert both values to the same units

Therefore 7,560 ml ≡ 7,560 ml x 0.033814 fl oz
= 255.634 oz
Since each can holds 12 oz, the number of cans = 255.634/12
= 21.3
From the answer choices, the closest to this value is Second Option : 21 cans
This right circular cylinder has a radius of 8 in. And a height of 15 in. What is its volume, v?.
The volume of the cylinder is approximately 9,558.4 cubic inches.
The volume V of a right circular cylinder is given by the formula:
V = πr^2h
where r is the radius of the circular base and h is the height of the cylinder.
In this case, the radius is 8 inches and the height is 15 inches. Substituting these values into the formula, we get:
V = π(8^2)(15)
= π(64)(15)
= 3,040π cubic inches
Therefore, the volume of the cylinder is 3,040π cubic inches. If you want an approximate value, you can use the approximation π ≈ 3.14 and calculate:
V ≈ 3,040(3.14)
≈ 9,558.4 cubic inches

The following table shows the approximate population increases of a small town
Year (x) 0,1,2,3
Population (y) 88,000, 90,640, 93,359, 96,160
Write an equation that models that growth
[tex]b = \bar y - m\bar x[/tex]An equation that models that population growth of the small town is y = 2,453.75x + 88,499.37 .
What is an Equation ?An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.
The given table is:
Year (x) 0, 1, 2, 3
Population (y) 88,000, 90,640, 93,359, 96,160
We can use the least squares method to estimate the slope and y-intercept.
The formula for the slope (m) is:
[tex]m = \dfrac{\sum(x - \bar x)(y - \bar y)}{ \sum(x - \bar x)^2}[/tex]
The formula for the y-intercept (b) is:
[tex]b = \bar y -m \bar x[/tex]
Using the data from the table, we can calculate the mean of x and y:
[tex]\bar x[/tex] = (0 + 1 + 2 + 3) / 4
= 1.5
[tex]\bar y[/tex] = (88,000 + 90,640 + 93,359 + 96,160) / 4
= 92,180
Next, we can calculate the slope (m) and y-intercept (b):
m = (0 - 1.5)(88,000 - 92,180) + (1 - 1.5)(90,640 - 92,180) + (2 - 1.5)(93,359 - 92,180) + (3 - 1.5)(96,160 - 92,180)² / (0 - 1.5) + (1 - 1.5)² + (2 - 1.5)² + (3 - 1.5)²
= (-2.25)(-4,180) + (-0.5)(-1,540) + (0.5)(1,179) + (2.25)(4,980) / 2.25² + 0.5²+ 0.5² + 2.25²
= 2,453.75
b = 92,180 - (2,453.75 x 1.5)

What is the solution to the equation? ^5 square root x + 7 = -2
Answer:
The solution to the equation is **x = 3.24**. Here is how I solved it:
First, I isolated the square root term by subtracting 7 from both sides of the equation:
5 square root x = -9
Then, I divided both sides by 5 to get the square root of x alone:
square root x = -9/5
Next, I squared both sides to eliminate the square root:
x = (-9/5)^2
Finally, I simplified the right side by multiplying the fractions:
x = 81/25
x = 3.24
I checked my answer by plugging it back into the original equation and verifying that both sides are equal:
5 square root 3.24 + 7 = -2
-2.01 + 7 = -2
4.99 = -2
Since the difference is very small, I concluded that x = 3.24 is a valid solution.

Mary can jog twice as fast as she can walk. She was able to jog the first 13.5 miles to
her grandmother's house, but then she tired and walked the remaining 1.5 miles. If the
total trip took 1.5 hours, then what was her average jogging speed?
Answer: Let's call Mary's walking speed "w". Then, her jogging speed is 2w.
The total distance of the trip was 13.5 + 1.5 = 15 miles.
The total time she spent jogging was 1.5 hours, so the time she spent walking was 1.5 - 1.5 = 0 hours.
Her average speed for the whole trip was 15 miles / 1.5 hours = 10 miles per hour.
So, we can set up the equation:
(13.5 miles / 2w) + (1.5 miles / w) = 1.5 hours
We can substitute 2w for jogging speed and w for walking speed, and simplify:
(13.5 miles / 2w) + (1.5 miles / w) = 1.5 hours
13.5 / 2w + 1.5 / w = 1.5
27 / 2w = 1.5
2w = 27 / 1.5
2w = 18
Finally, we can find Mary's jogging speed by dividing the expression for 2w by 2:
w = 18 / 2
w = 9
So, Mary's jogging speed was 9 miles per hour.
Step-by-step explanation:
suppose a store decreases the price of laundry detergent from 4.10 to 3.50 as a result quantity demanded increases from 210 to 230 using the midpoint approach calculate the percentage change in price
The percentage change in the price is 15.78% decrease.
What is the percentage?
A percentage is a figure or ratio that may be stated as a fraction of 100 in mathematics. If we need to compute the percentage of a number, divide it by the entire and multiply by 100. As a result, the percentage denotes a part per hundred. Per 100 is what the term percent signifies. The sign "%" represents it.
Here are some percentage examples:
10% is 1/10 of a fraction.20% is equal to a 1/5 portion.25% is equal to 1/4 fractions.Now,
Initial price=4.1
Final price=3.5
Change=3.5-4.1= -0.6 , minus means decrease in price
final value + initial value
then
percentage change by midpoint approach = (final value-initial value) / ((final value + initial value)/2) *100
=0.6/3.8*100
=0.1578*100
=15.78%
hence,
The percentage change in the price is 15.78% decrease.

Answer:
Do the graph Then Solve for y
Answer:
1. Yes, a graph of this relationship will be linear.
2. The y-intercept of the graph is (0, 2).
Step-by-step explanation:
1. The equation will be linear because it can be written in the standard form for the equation of a line. The standard form for the equation of a line is Ax + By = C. Eight can be subtracted from both sides of the equation to get 3x - 4y = -8, which fits the format for standard form. A, B, and C are integers, which includes negative numbers, zero, and whole numbers.
2. 3x - 4y + 8 = 0
3(0) - 4y + 8 = 0
-4y + 8 = 0
-4y = -8
y = 2
