Let the number of passed years be x.

Use the equation for half-life:

Substitute given values and solve for x:

a. The simultaneous linear equations for the given scenario in the form of ax + by = c are:

Demand equation: 5x + 3y = 30

Supply equation: 52x - 30y = -45

b. To solve the simultaneous equations using the matrix method, we can rewrite the equations in matrix form as AX = B, where A is the coefficient matrix, X is the variable matrix, and B is the constant matrix.

The coefficient matrix A:

| 5  3 |

| 52 -30 |

The variable matrix X:

| x |

| y |

The constant matrix B:

| 30 |

| -45 |

To find the equilibrium quantity and price, we can solve the system of equations AX = B by finding the inverse of matrix A and multiplying it with the matrix B. The solution is given by X = A^(-1) * B.

After performing the matrix calculations, we find that the equilibrium quantity (x) is approximately 0.66 thousand units, and the equilibrium price (y) is approximately $3.70 per unit.

Therefore, the equilibrium quantity is 0.66 thousand units, and the equilibrium price is $3.70 per unit.

Answer:

√(4.93 × 17.1) is about √(5 × 20) = √100 = 10. 0.209 is about 0.2, or 1/5.

So we have 10/0.2 = 100/2 = 50.

The probability that in a particular week there will be less than 2 accidents is approximately 0.90980.

To find the probability that there will be less than 2 accidents in a particular week in the factory, we can use the Poisson distribution formula.

The Poisson distribution is used to model the probability of a certain number of events occurring in a fixed interval of time or space when these events occur with a known average rate.

In this case, the mean number of accidents per week in the factory is given as 0.5. Let's denote this mean as λ.

The probability of having less than 2 accidents can be calculated as the sum of the probabilities of having 0 accidents and 1 accident.

Using the Poisson distribution formula, the probability of having k events in a given time interval is given by:

\(P(X = k) = (e^(-λ) * λ^k) / k!\)

For k = 0:

\(P(X = 0) = (e^(-0.5) * 0.5^0) / 0! = e^(-0.5)\)

For k = 1:

\(P(X = 1) = (e^(-0.5) * 0.5^1) / 1! = e^(-0.5) * 0.5\)

Now, let's calculate the probability of having less than 2 accidents:

\(P(X < 2) = P(X = 0) + P(X = 1) = e^(-0.5) + e^(-0.5) * 0.5\)

Using a calculator, we can compute this probability:

P(X < 2) ≈ 0.60653 + 0.30327 ≈ 0.90980

Rounded to five decimal places, the probability that in a particular week there will be less than 2 accidents is approximately 0.90980.

A straight line PPF indicates constant opportunity costs in production is TRUE.

The Production-Possibility Frontier (PPF) is a graphical representation of the maximum amount of two goods that can be produced given a certain number of resources.

If the PPF is a straight line, then the opportunity cost of producing an additional unit of one good is the same regardless of how much of that good is already being produced. This means that the resources used to produce the two goods are perfectly substitutable and there are no increasing opportunity costs.

However, if the PPF is a curved line, then the opportunity cost of producing an additional unit of one good increase as more of that good is produced. This is because the resources used to produce the two goods are not perfectly substitutable and there are increasing opportunity costs.

The actual length of the truck is 72 inches.

To find the length of the actual truck, we need to use the scale factor of 1:12. This means that for every 1 unit on the model, it represents 12 units on the actual truck.
Since the length of the model truck is 6 inches, we can multiply it by the scale factor of 12 to get the length of the actual truck.

1 (model unit) / 12 (actual units) = 6 inches (model length) / x (actual length)
To solve for x, we can cross-multiply:
1 * x = 12 * 6
x = 72 inches
Therefore, the length of the actual truck is 72 inches or 6 feet.

The equation of the parabola in vertex form that passes through the points (-2, 4) and (1, 0):

y = -2(x + 1)^2 + 2

The vertex form of a parabola is y = a(x - h)^2 + k, where (h, k) is the vertex of the parabola. In this case, the vertex is (-1, 2), so we can write the equation as y = -2(x + 1)^2 + 2.

To find the vertex of the parabola, we can take the average of the x-coordinates of the two points, and then take the average of the y-coordinates of the two points. The average of the x-coordinates is (-2 + 1)/2 = -0.5, and the average of the y-coordinates is (4 + 0)/2 = 2. Therefore, the vertex is (-0.5, 2).

Once we know the vertex, we can find the value of a by substituting the vertex coordinates into the vertex form of the parabola. Substituting (-0.5, 2) into the equation y = a(x - h)^2 + k, we get 2 = a(-0.5 - (-1))^2 + 2. Simplifying, we get 2 = a(0.25) + 2. Solving for a, we get a = -2.

Plugging in a = -2 into the vertex form of the parabola, we get y = -2(x + 1)^2 + 2. This is the equation of the parabola in vertex form.

Step-by-step explanation:

The central angle of this is 112 degrees. That is CAE is 112 degrees. That being the case, CDE is 90 + 90 + 112  = 292 Tangents make a 90 degree angle with the center of the circle.

CDE = 360 - 292 = 68

C

The measure of ∠CDE is 68degrees

This question bothers on circle geometry;

From the diagram, we can see that ACDE will form a quadrilateral. Since the sum of angles of a quadrilateral is 360degrees, hence;

\(<CDE + arcCE+<C+<E=360\)

From the diagram, since CD and DE are both tangential to the circle at point C and E, this shows that <E = <E = 90°

substituting the given values in the formula;

\(<CDE+112+90+90=360\\<CDE + 292=360\\<CDE=360-292\\<CDE =68^0\)

Hence the measure of ∠CDE is 68 degrees

The polynomial function f(x) = -4x⁵ + 15x⁴ - 17x³ + 6x² - 7x + 11 has a maximum of 2 positive real zeros and a maximum of 0 negative real zeros.

To determine the possible number of positive real zeros and negative real zeros of the polynomial function f(x) = -4x⁵ + 15x⁴ - 17x³ + 6x² - 7x + 11, we need to examine the signs of the coefficients.

For the positive real zeros:

- Count the number of sign changes in the coefficients or the sign changes in f(x) when substituting -x for x.

- The maximum number of positive real zeros is equal to the number of sign changes or less by an even number.

For the negative real zeros:

- Count the number of sign changes in the coefficients of f(-x) or f(x) when substituting -x for x.

- The maximum number of negative real zeros is equal to the number of sign changes or less by an even number.

Let's analyze the coefficients of the polynomial function: -4, 15, -17, 6, -7, 11

For the positive real zeros, there are 2 sign changes from negative to positive:

-4, 15, -17, 6, -7, 11

So, the maximum number of positive real zeros is 2 or less by an even number.

For the negative real zeros, there are no sign changes from positive to negative:

4, 15, 17, 6, 7, 11

Therefore, the maximum number of negative real zeros is 0.
