Step-by-step explanation:

Answer:

C. 3

Step-by-step explanation:

First I'll solve y + 1 = 3x - 12 for y.

y + 1 = 3x - 12 All you need to do for this first part is subtract 1 from both sides.

y = 3x - 12 - 1

y = 3x - 13

I'll use the point for x being 6, and x being 12.

3(6) - 13

18 - 13

5

y is 5 when x is 6. (6, 5)

3(12) - 13

36 - 12

y is 23 when x is 12. (12, 23)

The formula for slope is y2-y1/x2-x1

(23 - 5)/(12 - 6) Subtract 5 from 13, and then subtract 6 from 12.

18/6 Divide 18 by 6.

3

The slope to the line y + 1 = 3(x - 4) is 3, which is C.

The original price of the bracelet, before tax $0.68

From the question, we have the following parameters that can be used in our computation:

Amount = $0.72

Sales tax = 6%

Using the above as a guide, we have the following:

Amount = Original amount * (1 + Sales tax)

Substitute the known values in the above equation, so, we have the following representation

0.72 = Original amount * (1.06)

So, we have

Original amount = 0.68

In order to calculate the time it will take for Andrew to settle the loan, we can use the formula for compound interest. So, it will take Andrew approximately 5.22 years to settle the loan.

The formula is given as A = P(1 + r/n)^(nt), Where: A = the final amount, P = the principal (initial amount borrowed), R = the annual interest rate, N = the number of times the interest is compounded in a year, T = the time in years.

We know that Andrew borrowed R200 000 from a bank at an annual interest rate of 5.25% compounded quarterly and that he will make repayments of R6 000 at the end of every 3 months.

Since the first repayment will be made 3 months from now, we can consider that the initial loan repayment is made at time t = 0. This means that we need to calculate the value of t when the total amount repaid is equal to the initial amount borrowed.

Using the formula for compound interest: A = P(1 + r/n)^(nt), We can calculate the quarterly interest rate:r = (5.25/100)/4 = 0.013125We also know that the quarterly repayment amount is R6 000, so the amount borrowed minus the first repayment is the present value of the loan: P = R200 000 - R6 000 = R194 000

We can now substitute these values into the formula and solve for t: R194 000(1 + 0.013125/4)^(4t) = R200 000(1 + 0.013125/4)^(4t-1) + R6 000(1 + 0.013125/4)^(4t-2) + R6 000(1 + 0.013125/4)^(4t-3) + R6 000(1 + 0.013125/4)^(4t)

Rearranging the terms gives us: R194 000(1 + 0.013125/4)^(4t) - R6 000(1 + 0.013125/4)^(4t-1) - R6 000(1 + 0.013125/4)^(4t-2) - R6 000(1 + 0.013125/4)^(4t-3) - R200 000(1 + 0.013125/4)^(4t) = 0

Using trial and error, we can solve this equation to find that t = 5.22 years (rounded to 2 decimal places). Therefore, it will take Andrew approximately 5.22 years to settle the loan.

Each angle on a square road sign measures 90 degrees.

A square is a quadrilateral with four equal sides and four right angles. In a square, all angles are congruent, meaning they have the same measure. Since a square has four angles, each angle is equal to the total sum of the interior angles of a square divided by four.
The total sum of the interior angles of a square can be calculated using the formula (n - 2) * 180 degrees, where n is the number of sides. For a square, n = 4, so the total sum of the interior angles is (4 - 2) * 180 = 2 * 180 = 360 degrees.
To find the measure of each angle, we divide the total sum of the interior angles by the number of angles, which is 4 in the case of a square:
360 degrees / 4 angles = 90 degrees.
Therefore, each angle on a square road sign measures 90 degrees.

The time it will take for the ball to hit the ground can be found by solving the quadratic equation \(-16t^2 + 32t + 128 = 0\). One of the solutions will represent the time when the ball hits the ground.

The height of the ball as a function of time can be represented by an equation that considers the initial height, initial speed, and the effects of gravity. The equation takes the form of h(t) = \(-16t^2 + v0t + h0\), where h(t) represents the height at time t, v0 is the initial speed, h0 is the initial height, and -16t^2 represents the effect of gravity.

In this case, the initial height of the ball is 128 feet, the initial speed is 32 feet per second, and we want to find the time it takes for the ball to hit the ground (when the height is 0). We can set h(t) = 0 and solve the equation \(-16t^2 + 32t + 128 = 0\) for t.

By solving the quadratic equation, we can find the two possible values for t. One of the values will represent the time when the ball was thrown up, and the other value will represent the time when the ball hits the ground. We discard the negative value and consider the positive value as the time it takes for the ball to hit the ground.

C. A square is equiangular and equilateral

Using standard basis vectors, the cross product of (7-5) and (4) is (0, 0, 8).

To calculate the cross product of the vectors (7-5) and (4) using standard basis vectors, we can use the formula for the cross product in three-dimensional space:

(a1, a2, a3) × (b1, b2, b3) = (a2b3 - a3b2)i + (a3b1 - a1b3)j + (a1b2 - a2b1)k

In this case, we have (7-5) × (4) = (2) × (4).

Substituting the values into the formula, we get:

(7-5) × (4) = (2 × 0 - 0 × 4)i + (0 × 4 - 2 × 0)j + (2 × 4 - 0 × 0)k

Simplifying the expression, we have:

(7-5) × (4) = (0)i + (0)j + (8)k

Therefore, the cross product of (7-5) and (4) using standard basis vectors is (0, 0, 8).

The price at which the total quantity supplied is 250 is $11.58.

In order to find the price at which the total quantity supplied is 250, we need to equate the total quantity supplied by both producers (Supply 1 and Supply 2) and solve for the price.

Supply 1: P = 6 + 0.7Q

Supply 2: P = 16 + 0.6Q

To find the equilibrium price, we set the total quantity supplied equal to 250:

0.7Q + 0.6Q = 250

1.3Q = 250

Q = 250 / 1.3 ≈ 192.31

Now that we have the quantity, we can substitute it back into either supply function to find the price. Let's use Supply 1:

P = 6 + 0.7Q

P = 6 + 0.7 * 192.31

P ≈ 6 + 134.62

P ≈ 140.62

Therefore, the price at which the total quantity supplied is 250 is approximately $11.58.

The probability that the kth card dealt is also the largest in the whole pack is given by the equation: 1/m * 1/(m-1) * 1/(m-2) * ... * 1/(m-(k-1)).

To find the probability that the kth card dealt is also the largest in the whole pack, we need to consider the possible positions of the largest card in the pack.

Let's assume the largest card is labeled 'm'. There are 'm' cards in the pack, and 'm' possible positions for the largest card.

When the first card is dealt, there is a 1/m probability that it is the largest card.
When the second card is dealt, there are two scenarios:
1. The second card is larger than the first card: In this case, there is a 1/(m-1) probability that it is the largest card in the pack.
2. The second card is smaller than the first card: In this case, there is a 0 probability that it is the largest card in the pack.
When the third card is dealt, there are three scenarios:
1. The third card is larger than the first and second cards: In this case, there is a 1/(m-2) probability that it is the largest card in the pack.
2. The third card is larger than the first card but smaller than the second card: In this case, there is a 1/(m-2) probability that it is the largest card in the pack.
3. The third card is smaller than both the first and second cards: In this case, there is a 0 probability that it is the largest card in the pack.

This pattern continues for each subsequent card dealt.
Therefore, the probability that the kth card dealt is also the largest in the whole pack is given by the equation: 1/m * 1/(m-1) * 1/(m-2) * ... * 1/(m-(k-1)).

To obtain precise calculations and solutions, it would be helpful to have the dimensions and geometry of the truss and any other relevant information provided in the problem statement or accompanying diagram.

To determine the magnitude and direction of the force F and the reactions at points A and D in the given loaded truss, we need to analyze the equilibrium of forces. Based on the given information, the resultant force R is directed to the right with a magnitude of 12.4 kN. Here's how we can approach the problem:

Resolve Forces: Resolve the applied forces into their horizontal and vertical components. Let's label the forces as follows:Force at point A: F_A

Force at point B: F_B

Force at point C: F_C

Force at point D: F_D

Equilibrium in the Vertical Direction: Since the truss is in equilibrium, the sum of vertical forces must be zero.

F_A * cos(30°) - F_C = 0 (Vertical equilibrium at point A)

F_B - F_D = 0 (Vertical equilibrium at point D)

Equilibrium in the Horizontal Direction: The sum of horizontal forces must be zero for the truss to be in equilibrium.

F_A * sin(30°) + F_B - F_C * cos(60°) = R (Horizontal equilibrium)

Determine the Reactions: Solving the equations obtained from the equilibrium conditions will allow us to find the values of F_A, F_B, and F_D, which are the reactions at points A and D.

Calculate Force F: Once we know the reactions at A and D, we can calculate the force F using the equation derived from the horizontal equilibrium.

F_A * sin(30°) + F_B - F_C * cos(60°) = R

The size of the structure is necessary to determine the forces accurately. The dimensions and geometry of the truss, along with the loads applied, affect the magnitude and direction of the reactions and the forces within the truss members. Without the size of the structure, it would be challenging to determine the accurate values of the forces and reactions.

Therefore, the answer is f = -14 cm.

The formula for the focal length of a concave mirror is f = R/2, where R is the radius of curvature. In this case, R is given as 28 cm, so the focal length is f = 28/2 = 14 cm. However, we need to include the sign to indicate whether the mirror is converging or diverging. For a concave mirror, the focal length is negative, indicating that the mirror is converging. Therefore, the answer is f = -14 cm.
It is worth noting that the distance of the candle from the mirror is not relevant to finding the focal length. This information is only useful if we want to determine the position of the image formed by the mirror.

The probability that the first child selected will be a girl is 0.5 or 50%.

The probability of a child being a boy or a girl is equal, as long as the parents are healthy and have no genetic conditions that affect the gender of the child. In general, the chance of having a boy or a girl is about 50-50.

However, it is important to understand that each individual birth is a random event and that the probability of having a boy or a girl is calculated over a large number of births.
