To determine if W is a vector space, we need to check whether it satisfies the closure axioms of a vector space.

In particular, we need to check whether W is closed under vector addition and scalar multiplication.

Let's first consider vector addition. Suppose that u = (4a, 3b, 0) and v = (a, b, c - 2a) are two arbitrary vectors in W. Then their sum is given by:

u + v = (4a, 3b, 0) + (a, b, c - 2a) = (5a, 4b, c - 2a)

We see that the sum is also of the form shown in the definition of W, which means that W is closed under vector addition.

Now, let's consider scalar multiplication. Suppose that u = (4a, 3b, 0) is an arbitrary vector in W, and let c be an arbitrary real number. Then their scalar product is given by:

c * u = c * (4a, 3b, 0) = (4ca, 3cb, 0)

We see that the scalar product is also of the form shown in the definition of W, which means that W is closed under scalar multiplication.

Therefore, we have shown that W is closed under both vector addition and scalar multiplication, and is thus a vector space.

To find a set S of vectors that spans W, we can find a set of vectors such that every vector in W can be written as a linear combination of the vectors in S. One possible set S is:

{(4, 0, 0), (0, 3, 0), (0, 0, 1), (-2, 0, 0)}

We see that any vector in W can be written as a linear combination of these four vectors, as follows:

(4a, 3b, 0) = 4(a, 0, 0) + 3(0, b, 0) + 0(0, 0, 1) + (-2)(-2, 0, 0)

(a, b, c - 2a) = 1(4, 0, 0) + 0(0, 3, 0) + 1(0, 0, 1) + (-2)(-2, 0, 0)

Therefore, the set S = {(4, 0, 0), (0, 3, 0), (0, 0, 1), (-2, 0, 0)} spans W.

(a) For one unique solution, c cannot be equal to 0 or 2.

(b) For no solution, c must be equal to 0 or 2.

(c) For infinite many solutions, c can be any value except for 0 or 2.

To solve the linear system, we can use row operations to reduce the augmented matrix to the echelon form. This gives us:

(1) c 1 0 | x1

(2) 0 c-2 2 | x2

(3) 0 0 c-1 | x3-2x2

From this, we can see that the system has one unique solution if and only if the matrix is invertible, which occurs when c is not equal to 0 or 2. If c is equal to 0 or 2, then the matrix is not invertible, and the system has no solution.

If c is not equal to 0 or 2, then the matrix is in echelon form, and we can solve for x1, x2, and x3. In this case, the system has infinitely many solutions, as there is at least one free variable (x2 or x3, depending on the value of c).

Therefore, the values of c that lead to one unique solution are all real numbers except for 0 and 2, the values that lead to no solution are 0 and 2, and the values that lead to infinitely many solutions are all real numbers except for 0 and 2.

The angle ACB would be 80 degrees.

What is tangent to a circle?

The tangent always makes a single-point contact with the circle. It never intersects the circle twice. Tangents from an external point to a circle have the same length.

In the given figure,

angle AOB = 40.

So angle OBA = 40.

Then the angle AOB = 180 - 40 -40

                          AOB = 100.

By the theorem of circles,

          AOB + ACB = 180

          100 + ACB = 180

              ACB = 80.

Hence, the angle ACB would be 80 degrees.

Answer:

\((\sqrt[3]{729} )^{3}\) + 24 can be simplified to 753.

Step-by-step explanation:

If you take the root of a number to a specific number, then square that by the same number you took the root by, then you will have the same number you started with. In this case, \(\sqrt[3]{729}\) equals 9, and \(9^{3}\) equals 729, so \((\sqrt[3]{729} )^{3}\) equals 729. 729 + 24 = 753, so that is the simplified answer.

Variables that indicate the distance a target is from the level achieved are called performance metrics or progress indicators.


Variables that indicate the distance a target is from the level achieved are called performance metrics or progress indicators. These variables help measure and track progress towards a goal by providing a quantitative or qualitative measure of how far the target is from the desired level of achievement.

Performance metrics can be represented in various forms, such as distance covered, percentage completed, points earned, or even subjective evaluations. For example, in a fitness program, a performance metric could be the number of miles run or the number of push-ups completed.

These metrics enable individuals or organizations to assess their progress and make necessary adjustments to reach their desired outcomes.

Hey! Your answer to this question would be : x = 1, -5

The expected on-order inventory is approximately 80 units (rounded to the nearest integer).

1. Determine the average demand during the lead time:

Since the mean demand per period is 60 and the lead time is 2 periods, the average demand during the lead time is

60 × 2 = 120 units.

2. Determine the standard deviation of the demand during the lead time:

As the demand follows a normal distribution with a standard deviation of 10 per period, the standard deviation during

the lead time (2 periods) is calculated as sqrt(2) × 10 ≈ 14.14 units.

3. Calculate the expected on-order inventory:

Subtract the average demand during the lead time from the order-up-to level. In this case, it's 200 (order-up-to level) -

120 (average demand during lead time) = 80 units.

So, the expected on-order inventory is approximately 80 units (rounded to the nearest integer).

Volume of the pyramid is 4390.74 and base area is 439.07 cubic inches.

The given figure is a hexagonal pyramid.

The base of the pyramid is hexagon.

We have to find the base of the pyramid by formula :

Base area = 3√3/2a²

Where a is the base length.

Base area = 3√3/2(13)²

= 3√3/2 ×169

=439.07 square inches.

Volume =√3/2b²h

h is height which is 30 in and b is base length of 13 in.

Volume =√3/2×169×30

=√3/2×5070

=2535×√3

=4390.74 cubic inches.

Hence, volume of the pyramid is 4390.74 and base area is 439.07 cubic inches.

Answer:

B. y = 2x + 5

Step-by-step explanation:

Slope intercept formula y=mx+b

Slope formula y1-y2/x1-x2

First, let's find slope since we are provided 2 pairs of points, we can simply plug in our numbers in the Slope formula (y1-y2/x1-x2)

5-7/0-1

-2/-1

2/1

=2

Slope (m) = 2

Now using slope let's find our y-intercept (b) to plugin in our slope intercept formula (y=mx+b) for this let's use point 0,5

y=2x+b

5=2(0)+b

5=b

Y-intercept (b) = 5

Now let's plug in the slope (m) and the y-intercept (b) into the slope-intercept formula (y=mx+b)

y=mx+b

y=2x+5

So therefore our answer is B

2) Pi is an irrational number as it repeats forever.

Answer:

Let a = side length of a cube

Let S = surface area of a cube

Area of a square = a²

Since a cube has 6 square sides:  S = 6a²

To make a the subject:

S = 6a²

Divide both sides by 6:

\(\sf \implies \dfrac{S}{6}=a^2\)

Square root both sides:

\(\sf \implies a=\sqrt{\dfrac{S}{6}}\)

(positive square root only as distance is positive)

-----------------------------------------------------------------------------------------------

\(\sf x=-3-\sqrt{2} \implies (x+[3+\sqrt{2}])=0\)

\(\sf x=-3+\sqrt{2} \implies (x+[3-\sqrt{2}])=0\)

Therefore,

\(\sf y=a(x+[3+\sqrt{2}]) (x+[3-\sqrt{2}])\)  for some constant a

Given the y-intercept is at (0, -5)

\(\sf \implies a(0+3+\sqrt{2}) (0+3-\sqrt{2})=-5\)

\(\sf \implies a(3+\sqrt{2}) (3-\sqrt{2})=-5\)

\(\sf \implies a(9-2)=-5\)

\(\sf \implies 7a=-5\)

\(\sf \implies a=-\dfrac57\)

Substituting found value of a into the equation and simplifying:

\(\sf y=-\dfrac57(x+[3+\sqrt{2}]) (x+[3-\sqrt{2}])\)

\(\sf \implies y=-\dfrac57(x^2+6x+7)\)

\(\sf \implies y=-\dfrac57x^2-\dfrac{30}{7}x-5\)
