Step-by-step explanation: The solution to this system of equations will be where the two lines on the graph intersect with each other.

Notice that both of them intersect to the left of the y-axis which means our x - coordinate must be negative.

They also intersect above the x-axis so our y-coordinate must be positive.

So the only option with a negative x-coordinate

and a positive y-coordinate is (-1/4, 3/4).

Answer:

x = 4.5

Step-by-step explanation:

Let's begin by writing the equation in words to express the worker's earnings:

   Rate x Time = Earnings

Now let's rewrite this equation replacing the words with our given numerical facts and our unknown (x):

   Rate x Time = Earnings  

   Rate = $7.50 per hour

   Time = x (# hours worked)

   Earnings = 33.75

   (7.50)(x) = 33.75

Finally, we'll solve our equation for our unknown (x):

   (7.50)(x) = 33.75

   7.50x = 33.75

         x = 33.75/7.50

         x = 4.5 (# hours worked)

The height to which the hollow sphere rolls up the incline is the same as the height to which the hollow cylinder rolls up, which is 1.0 m in this case.

To determine the height to which the hollow sphere rolls up the incline, we can use the principle of conservation of energy. The initial kinetic energy of both the hollow cylinder and hollow sphere is the same since they have the same mass and initial velocity. This kinetic energy is converted into potential energy as they roll up the incline. The potential energy gained by an object of mass m and height h is given by the formula:

PE = mgh

Since both the hollow cylinder and hollow sphere have the same mass, we can compare their potential energies. Let's assume the potential energy gained by the hollow cylinder is PE_cylinder and the potential energy gained by the hollow sphere is PE_sphere.

PE_cylinder = mgh_cylinder  ... (1)

PE_sphere = mgh_sphere  ... (2)

Since the initial velocity and mass are the same for both objects, we can equate their potential energies:

PE_cylinder = PE_sphere

mgh_cylinder = mgh_sphere

h_cylinder = h_sphere

Therefore, the height to which the hollow sphere rolls up the incline is the same as the height to which the hollow cylinder rolls up, which is 1.0 m in this case.

The expected amount of dollars to be paid by Miami Co. for the pesos in one year is approximately $1,270,588.24. option e is correct.

We need to consider the inflation rates and the concept of purchasing power parity (PPP).

Purchasing power parity (PPP) states that the exchange rate between two currencies should equal the ratio of their price levels.

Let us assume that PPP holds, meaning that the change in exchange rates will be proportional to the inflation rates.

First, let's calculate the expected exchange rate in one year based on the inflation differentials:

Expected exchange rate = Spot rate × (1 + U.S. inflation rate) / (1 + Mexican inflation rate)

= 0.12× (1 + 0.08) / (1 + 0.02)

= 0.12 × 1.08 / 1.02

= 0.1270588235

Now, we calculate the expected amount of dollars to be paid by Miami Co. for 10 million Mexican pesos in one year:

Expected amount of dollars = Expected exchange rate × Amount of Mexican pesos

Expected amount of dollars = 0.1270588235 × 10,000,000

Expected amount of dollars = $1,270,588.24

Therefore, the expected amount of dollars to be paid by Miami Co. for the pesos in one year is approximately $1,270,588.24.

The altitude of the airplane viewed from the helicopter is found to be 10459.5 ft.

The height of the helicopter is 1600 ft. above the ground and it spots a airplane above it.

The horizontal distance between the helicopter and the airplane is 3055 ft. and the angle of elevation 71 degrees.

Now, let us say that the airplane is flying at x ft. from the ground.

Now, the vertical distance between the helicopter and the airplane is (x-1600)ft.

Now, using tan theta,

tanA = perpendicular/base

Here, A is 71 degrees,

Perpendicular = (x-1600)ft.

Base = 3055ft.

Putting values,

tan(71) = x-1600/3055

2.9 = x-1600/3055

8859.5 = x-1600

x = 10459.5 ft.

So, the altitude of the airplane is 10459.5 ft.

Given matrix is A = 1 -3 -9 8 5 0 1 2 8 -6 0 0 1 -9 8 0 0 0 -3 -6To determine the dimensions of Nul A, Col A, and Row A for the given matrix.

The dimension of Null(A) can be found by solving the equation Ax = 0.The augmented matrix [A 0] can be row reduced to [R 0] where R has n leading 1s and n-k trailing zeros, where k = dim(Nul A).The Row Reduced Echelon Form (RREF) of matrix A can be written as1 0 -3 0 7 0 0 1 -2 0 0 0 0 0 0 0 0 0 1 -2 0 0 0 0where RREF has 3 leading 1's and 2 trailing zeros, so

dim(Nul A) = k

= 2.

Hence, dimension of Null(A) is 2.The dimension of Col A can be determined by considering the number of leading 1's in the RREF of A.The RREF of matrix A is1 0 -3 0 7 0 0 1 -2 0 0 0 0 0 0 0 0 0 1 -2 0 0 0 0The first, second, and fifth columns have leading 1's. Hence, the dimension of Col A = 3.

The dimension of Row A is same as the number of leading non-zero rows in the RREF of A.Hence, the dimension of Row A = 3.Dimensions of Nul A, Col A and Row A are 2, 3, and 3 respectively.

The probability that the entire shipment will be kept by Dell even though the shipment has 10% defective microprocessors is approximately 0.5905. Hence the correct answer is (a) 0.5905.

To calculate the probability that the entire shipment will be kept by Dell even though the shipment has 10% defective microprocessors, we can use the concept of binomial probability.

Let's denote the probability of a microprocessor being defective as p = 0.10 (10% defective) and the number of microprocessors Dell tests as n = 5.

We want to calculate the probability that all five tested microprocessors are non-defective, which is equivalent to the probability of having zero defective microprocessors in the sample.

Using the binomial probability formula, the probability of getting exactly k successes (non-defective microprocessors) in n trials is:

\(\[P(X = k) = \binom{n}{k} \cdot p^k \cdot (1 - p)^{n - k}\]\)

For this case, we want to calculate P(X = 0), where X represents the number of defective microprocessors.

\(\[P(X = 0) = \binom{5}{0} \cdot 0.10^0 \cdot (1 - 0.10)^{5 - 0} \\= 1 \cdot 1 \cdot 0.9^5 \\\\approx 0.5905\]\)

Therefore, the correct answer is (a) 0.5905.

We can say that after answering the offered question As a result, the equation for the circle with centre (7, -7) and point (11, -3) i\((x - 7)2 + (y + 7)2 = 32.\)

An equation is a mathematical statement that proves the equality of two expressions connected by an equal sign '='. For instance, 2x – 5 = 13. Expressions include 2x-5 and 13. '=' is the character that links the two expressions. A mathematical formula that has two algebraic expressions on either side of an equal sign (=) is known as an equation. It depicts the equivalency relationship between the left and right formulas. L.H.S. = R.H.S. (left side = right side) in any formula.

Determine the radius:

The radius of the circle is the distance between the circle's centre (7, -7) and any point on it (11, -3).

We may calculate the distance using the distance formula:

\(r = \sqrt((11 - 7)^2 + (-3 - (-7))\\v^2)\\r = \sqrt(4^2 + 4^2)\\r = \sqrt(32) (32)\)

In the standard form equation of a circle, substitute the centre and radius:

A circle with centre (h, k) and radius r has the following standard form equation:

\((x - h)^2 + (y - k)^2 = r^2\)

With h = 7, k = -7, and r = sqrt(32), we get:

\((x - 7)^2 + (y + 7)^2 = 32\)

To maximize the function f(x, y) = 6xy subject to the constraint equation x + y = 14, we can use the method of Lagrange multipliers.

First, we define the Lagrangian function L(x, y, λ) as follows:

L(x, y, λ) = 6xy + λ(x + y - 14)

We need to find the critical points of L(x, y, λ), which satisfy the following equations:

∂L/∂x = 6y + λ = 0 (Equation 1)

∂L/∂y = 6x + λ = 0 (Equation 2)

∂L/∂λ = x + y - 14 = 0 (Equation 3)

Solving this system of equations, we can find the values of x, y, and λ.

From Equation 1, we have:

6y + λ = 0 ⟹ 6y = -λ ⟹ y = -λ/6 (Equation 4)

From Equation 2, we have:

6x + λ = 0 ⟹ 6x = -λ ⟹ x = -λ/6 (Equation 5)

Substituting Equations 4 and 5 into Equation 3, we get:

(-λ/6) + (-λ/6) - 14 = 0

⟹ -λ/3 - 14 = 0

⟹ -λ/3 = 14

⟹ λ = -42

Using λ = -42 in Equations 4 and 5, we find:

y = -(-42)/6 = 7

x = -(-42)/6 = 7

Therefore, the maximum value of f(x, y) occurs when x = 7, y = 7, and the maximum value is:

f(7, 7) = 6 * 7 * 7 = 294

Problem 1: The standard matrix A of T is A = [[1, 5], [2, 5], [3, 0], [4, 0]], and T(x) = [7, -1, 9, 8].

Problem 2: The coordinate vectors of the polynomials are [1, 0, 2], [4, 1, 5], and [3, 0, 2], and they are linearly independent in P2.

Problem 1:
The standard matrix A of T is given by the column vectors T(e1) and T(e2). Therefore, we can write A as:
A = [T(e1) T(e2)] = [(1, 2, 3, 4) (5, 5, 0, 0)] = [[1, 5], [2, 5], [3, 0], [4, 0]]

So the standard matrix A of T is:
A = [[1, 5], [2, 5], [3, 0], [4, 0]]
Now, to find T(x), where x=(2,-3), we simply multiply A by x:
T(x) = A*x = [[1, 5], [2, 5], [3, 0], [4, 0]]*[(2),(-3)] = [(-13), (-11), (6), (8)]
Therefore, T(x) = (-13, -11, 6, 8)

Problem 2:
The standard basis for P2 is {1, t, t^2}. The coordinate vectors of the polynomials 1+2t^2, 4+t+5t^2, and 3+2t relative to the standard basis are:
[1, 0, 2], [4, 1, 5], and [3, 2, 0]
To show that these vectors are linearly independent, we need to show that the only solution to the equation c1[1, 0, 2] + c2[4, 1, 5] + c3[3, 2, 0] = [0, 0, 0] is c1=c2=c3=0.
This equation can be written as a system of equations:
c1 + 4c2 + 3c3 = 0
c2 + 2c3 = 0
2c1 + 5c2 = 0
Solving this system of equations, we find that the only solution is c1=c2=c3=0. Therefore, the vectors [1, 0, 2], [4, 1, 5], and [3, 2, 0] are linearly independent.

Answer:

-2, 8/3

Step-by-step explanation:

You can consider the area to be that of a trapezoid with parallel bases f(a) and f(4), and width (4-a). The area of that trapezoid is ...

 A = (1/2)(f(a) +f(4))(4 -a)

 = (1/2)((3a -1) +(3·4 -1))(4 -a)

 = (1/2)(3a +10)(4 -a)

We want this area to be 12, so we can substitute that value for A and solve for "a".

 12 = (1/2)(3a +10)(4 -a)

24 = (3a +10)(4 -a) = -3a² +2a +40

 3a² -2a -16 = 0 . . . . . . subtract the right side

 (3a -8)(a +2) = 0 . . . . . factor

Values of "a" that make these factors zero are ...

 a = 8/3, a = -2

The values of "a" that make the area under the curve equal to 12 are -2 and 8/3.

Alternate solution

The attachment shows a solution using the numerical integration function of a graphing calculator. The area under the curve of function f(x) on the interval [a, 4] is the integral of f(x) on that interval. Perhaps confusingly, we have called that area f(a). As we have seen above, the area is a quadratic function of "a". I find it convenient to use a calculator's functions to solve problems like this where possible.
