find all values of x such that (6, x, −11) and (5, x, x) are orthogonal. (enter your answers as a comma-separated list.)x = ___
Answers
The values x such that (6, x, −11) and (5, x, x) are orthogonal is 6,5.
The orthogonal vectors have dot product to be zero. Thus, the formula to be used is -
a . b = a1b1 + a2b2 + a3b3, where a1, a2 and a3 are components a vector and b1, b2 and be are components of b vector.
Keep the values in formula -
a . b = 6(5) + x² + (-11)x
a . b = 30 + x² - 11x = 0
So, x² - 11x + 30 = 0
x(x - 6) - 5(x - 6) = 0
(x - 6) (x - 5) = 0
So, the value of x is 6,5.

the demand curve for original iguanawoman comics is given by q = (469 − p)2 150 (0 ≤ p ≤ 469), where q is the number of copies the publisher can sell per week if it sets the price at $p.
Answers
These points the boundaries of the demand curve a price of $0 the maximum number of copies per week is (469² / 150).
To analyze the demand curve for Original Iguana woman comics,
q = (469 − p)² / 150
In this equation, q represents the number of copies the publisher can sell per week if they set the price at $p.
The equation is quadratic, with (469 - p)² as the numerator and 150 as the denominator. The numerator represents the decreasing relationship between price and quantity demanded, indicating that as the price increases, the quantity demanded decreases.
To better understand the demand curve, examine a few key points:
When p = 0:
q = (469 - 0)² / 150
= 469² / 150
When p = 469:
q = (469 - 469)²/ 150
= 0² / 150
= 0

For an economy the following functions have been given: C = 100 + 0.8Y S = -100 + 0.2Y I = 120 – 5r Ms = 120 Md = 0.2Y – 5r Calculate the following: (a). IS equation (5) (b). LM equation (5) (c). equilibrium level of income (5) (d) equilibrium level of interest rate.
Answers
To solve for the IS-LM equilibrium in an economy, we need to calculate the IS equation, LM equation, equilibrium level of income, and equilibrium level of interest rate. Given the functions for consumption (C), saving (S), investment (I), money supply (Ms), and money demand (Md), we can derive these values.
(a) IS equation:
The IS equation represents the equilibrium condition in the goods market. It is derived by equating national income (Y) with aggregate demand (C + I + G), where G represents government spending. In this case, the equation is:
Y = C + I
Substituting the given consumption and investment functions, we have:
Y = (100 + 0.8Y) + (120 - 5r)
Simplifying the equation, we get:
Y = 220 + 0.8Y - 5r
(b) LM equation:
The LM equation represents the equilibrium condition in the money market. It is derived by equating money supply (Ms) with money demand (Md). In this case, the equation is:
Ms = Md
Substituting the given money supply and money demand functions, we have:
120 = 0.2Y - 5r
(c) Equilibrium level of income:
To find the equilibrium level of income, we solve the IS equation for Y. Rearranging the IS equation from part (a), we get:
0.2Y = 220 - 5r
Y = (220 - 5r) / 0.2
(d) Equilibrium level of interest rate:
To find the equilibrium level of interest rate, we solve the LM equation for r. Rearranging the LM equation from part (b), we get:
5r = 0.2Y - 120
r = (0.2Y - 120) / 5
By substituting the equilibrium level of income (Y) into the LM equation, we can find the corresponding equilibrium level of interest rate (r). Similarly, by substituting the equilibrium level of interest rate (r) into the IS equation, we can find the corresponding equilibrium level of income (Y). These values represent the IS-LM equilibrium in the economy.

Nicole can pick forty bushels of apples in
15 hours. Carlos can pick the same amount
in 11 hours. How long would it take them
if they worked together?
Answers
Step-by-step explanation:
Given:
Work = 40 Bushels of Apples
Time of Nicole = 15 Hours
Time of Carlos = 11 Hours
Unknown:
N = Nicole's Rate
C = Carlos' Rate
Equation:
W = r * t
Solution:
First, get Nicole's Rate
40 = N * 15
N = 40 / 15
Second, get Carlos' Rate
40 = C * 11
C = 40/11
Then, get the time
40 = ( N + C ) * t
40 = ( 40/15 + 40/11 ) * t
40 = 208/33 t
40 / (208/33) = t
t = 165 / 26 or 6.3462 Hours
Statement:
Therefore, it would take them approxmately 6.35 hours if they worked together.

Answers
The distance from the point (5, 2, -1) to the line defined by
x=2+t,
y=1-3t,
z=4-2t is given by
d = √(6) √(9t² - 6t + 5) / √(10).
To find the distance between the point (5, 2, -1) and the line defined by x=2+t,
y=1-3t,
z=4-2t, we can use the formula
d=|a|/|a×b|, where a is the vector QR and b is the vector QP.
Find the vectors a and b:
Vector a = QR
= (2+t - 2, 1-3t - 2, 4-2t - (-1))
= (t, -3t-1, 5-2t)
Vector b = QP
= (5 - (2+t), 2 - (1-3t), -1 - (4-2t))
= (3-t, 3t-1, -5+2t)
Calculate the cross product of a and b:
a × b = [(3t-1)(-5+2t) - (5-2t)(3t-1)]i - [(5-2t)(t) - (3-t)(-5+2t)]j + [(5-2t)(-3t-1) - (3-t)(3t-1)]k
= (-2t² - 11t + 5)i + (3t² - 8t + 5)j + (-6t² - 6t + 8)k
Find the magnitudes of a and a × b:
|a| = √(t² + (-3t-1)² + (5-2t)²) = √(9t² - 6t + 6)
|a × b| = √((-2t² - 11t + 5)² + (3t² - 8t + 5)² + (-6t² - 6t + 8)²)
= √(45t⁴ + 90t³ - 30t² - 20t + 90)
Calculate the distance:
d = |a|/|a × b| = √(9t² - 6t + 6) / √(45t⁴ + 90t³ - 30t² - 20t + 90)
Therefore, the distance from the point (5, 2, -1) to the line
x=2+t,
y=1-3t,
z=4-2t is given by
d = √(9t² - 6t + 6) / √(45t⁴ + 90t³ - 30t² - 20t + 90).

The given is the Emotional Intelligence Quotient (EQ) score of a grade 8 class is normally distributed with a mean of 80 and a standard deviation of 20, and a random sample of 36 grade 8 learners is selected. The value of x is to be determined such that P(x << 80) = 0.4918.
The population mean is given by μ = 80.The standard deviation of the sample is given by:σ/√n = 20/√36 = 20/6.∴ Standard Error = σ/√n = 20/6 ≈ 3.33.Now, we have to find the z-score associated with a tail probability of 0.4918/2 = 0.2459.Using the standard normal distribution table, we get that the z-value associated with a tail probability of 0.2459 is approximately 0.67.
Now, using the formula for z-score: z = (x - μ) / Standard Error 0.67 = (x - 80) / 3.33 0.67 x 3.33 = x - 80 2.2301 + 80 = x 82.2301 = xThus, the value of x is 82.2301. Therefore, the option (a) 84 and the solution is provided above.

Line l can be reflected over a horizontal line to map onto line m.
Line l can be reflected over a vertical line to map onto line m.
Line l can be translated to map onto line m.
Answers
Lines l and m are parallel; line l will map onto line m with a 90° rotation; line l can map onto line m with a vertical line of reflection.
Do you have any explanations as to why the lines L and m are parallel?L and m are not parallel because the sum of the co-interior angles on the same side of the transversal does not equal 180 degrees.In the event when two lines, l and m, are in the same plane but do not cross, they are said to be parallel.We are aware that the equivalent angles are equal if they are parallel and a transversal is drawn to intersect them both. Accordingly, these are x and y. As a result, we can conclude that x and y are equivalent if l and m are parallel.If two lines, l and m, are in the same plane and do not cross one another, then they are parallel.To learn more about Lines refer to:

Find the volume of the sphere.
Answers
The volume of the sphere with a diameter of 6 mi is approximately 113.04 cubic miles.
What is the volume of the sphere?A sphere is simply a three-dimensional geometric object that is perfectly symmetrical in all directions.
The volume of a sphere is expressed as:
Volume = (4/3)πr³
Where r is the radius of the sphere and π is the mathematical constant pi (approximately equal to 3.14).
From the image:
Diameter d = 6 mi
Radius r = diamter/2 = 6/2 = 3 mi
Plug the value into the above formula and solve for the volume:
Volume = (4/3)πr³
Volume = (4/3) × 3.14 × (3 mi)³
Volume = (4/3) × 3.14 × 27 mi³
Volume = 113.04 mi³
Therefore, the volume is 113.04 cubic miles.

statistics computed for larger random samples are less variable than the statistic computed for smaller random samples
Answers
Statistics computed for larger random samples tend to be less variable compared to statistics computed for smaller random samples.
This statement is based on the concept of the Central Limit Theorem (CLT) in statistics. According to the CLT, as the sample size increases, the distribution of the sample mean approaches a normal distribution regardless of the shape of the population distribution. This means that the variability of the sample mean decreases as the sample size increases.
The variability of a statistic is commonly measured by its standard deviation or variance. When working with larger random samples, the individual observations have less impact on the overall variability of the statistic. As more data points are included in the sample, the effects of outliers or extreme values tend to diminish, resulting in a more stable and less variable estimate.
In practical terms, this implies that estimates or conclusions based on larger random samples are generally considered more reliable and accurate. Researchers and statisticians often strive to obtain larger sample sizes to reduce the variability of their results and increase the precision of their statistical inferences.
