The trooper overtakes the car at the point where the solid black line (representing the car's position) intersects with the dashed blue line (representing the trooper's position) on the position versus time graph.

In the position versus time graph, the trooper overtakes the car when their respective positions on the graph intersect. This intersection represents the point in time when the trooper catches up with and overtakes the car. By reading the time value on the x-axis at this intersection point, we can determine the exact time (in seconds) at which the trooper overtakes the car.  

The solid black line represents the car's position, and the dashed blue line represents the trooper's position. As time progresses, the car's position increases at a certain rate, while the trooper's position increases at a different rate. At the point of intersection, the trooper has covered enough distance to catch up with and surpass the car.

By analyzing the position versus time graph and identifying the point of intersection, we can extract the corresponding time value to determine when the trooper overtakes the car.

The perimeter of a semicircle is the sum of the curved boundary and the straight diameter, which is equal to half the circumference of the full circle plus the diameter.

To find the best approximation for the perimeter of a semicircle with a diameter of 12 cm, we need to calculate half the circumference of the corresponding full circle and add the diameter to it.

The formula for the circumference of a circle is C = πd, where C represents the circumference and d represents the diameter. Since we have a semicircle, we only need half the circumference.

Given the diameter of 12 cm, the radius (r) is half of that, which is 6 cm.

Now, we can calculate the perimeter:

Perimeter = (π * 12 cm) / 2 + 12 cm

= (3.14159 * 12 cm) / 2 + 12 cm

= 18.84956 cm + 12 cm

≈ 30.84956 cm

Therefore, the best approximation for the perimeter of a semicircle with a diameter of 12 cm is approximately 30.84956 cm.

Answer:

m = -3/4

Step-by-step explanation:

Let's look at how much x and y change as we move from A to B:

x increases by 6, from -3 to 3, and y increases by 8, from 7 to 15.  Thus, the slope, m, is rise / run, or (change in y):  m = 8/6 = 4/3.

Now any line perpendicular to AB has a slope which is the negative reciprocal of this 4/3:  m = -3/4

The standard error of the estimate is like a standard deviation for all error scores in a regression.

The standard deviation of the sample distribution is referred to as the standard error in statistics. In most cases, the sample mean of a data set differs from the actual population mean. SE is used to denote it. It is used to gauge how well a sample of a population represents that population.

The measure of the sample mean of the population is expressed as the standard deviation of the measure of the standard error of the mean, also known as the standard deviation of the mean. It is referred to as SEM. For instance, the sample mean typically serves as an estimator of the population mean. However, if we take yet another sample from the same population, it can yield a different result.

Answer:

50

Step-by-step explanation:

40+90=130

180-130=50

Answer:

The measure of the missing angle is 50°.

Step-by-step explanation:

☆A triangle equals 180°.

☆A right angle equals 90°

☆We have two angles given to us, however one out of the two angles might be tricky for some to figure out.

☆An angle, we obviously see, is 40°.

☆The right angle, (the one with a box) equals 90°, so therefore, the value of that angle is 90°.

☆In order to find the value of the last angle, we are going to have to subtract the sum of both numbers from 180°.

☆We are subtracting it from 180° because a triangle equals 180°.

☆An equation would look like:

\(40 + 90 + x= 180\)

☆The X indicated in the equation represents the unknown angle.

☆Let's solve the equation.

☆\(40 + 90 + x = 180 \\ 130 + x = 180 \\ \frac{ - 130 \: \: \: \: \: \: = - 130}{x = 50} \)

☆Without an equation, you could just add both angles, and subtract it from 180.

☆\(40 + 90 = 130 \\ 180 - 130 = 50\)

☆Therefore, the missing angle is 50°.

The given differential equation is: y''-2y'-3y=f(t)The form of a particular solution of the differential equation is to be determined given that f(t) = 12 sin(3t).The characteristic equation of the differential equation is: m² - 2m - 3 = 0 which gives the roots: m = -1, 3.

Therefore, the complementary function is given by:

y_c = c₁e^(-t) + c₂e^(3t)

where c₁ and c₂ are constants.To find a particular solution, we need to guess the form of the solution based on the form of the non-homogeneous term f(t).Since f(t) is a sine function, we guess the solution to be of the form yp = A sin(3t) + B cos(3t) where A and B are constants.We find the first and second derivatives of yp:

y'_p = 3A cos(3t) - 3B sin(3t)y''_p = -9A sin(3t) - 9B cos(3t)

Substituting the values in the differential equation:

y''-2y'-3y=f(t)-9A sin(3t) - 9B cos(3t) - 6A cos(3t) + 6B sin(3t) - 3A sin(3t) - 3B cos(3t) = 12 sin(3t)

Collecting the coefficients of sin(3t) and cos(3t), we get:

(-9A - 3B)sin(3t) + (6B - 3A)cos(3t) = 12 sin(3t)

Comparing the coefficients of sin(3t) and cos(3t), we get:

-9A - 3B = 12 ...(1)6B - 3A = 0 ...(2)

Solving the equations (1) and (2), we get A = -4 and B = -2.Substituting the values of A and B in the particular solution, we get: yp(t) = -4sin(3t) - 2cos(3t)Therefore, the form of the particular solution is: yp(t) = -4sin(3t) - 2cos(3t).

The minimum score needed to receive a grade of A is approximately 86.06.

To find the minimum score needed to receive a grade of A, we need to determine the cutoff point that corresponds to the top 12.3 percent of students in a normal distribution with a mean of 65 and a standard deviation of 18.

First, we need to find the z-score associated with the top 12.3 percent.

The z-score represents the number of standard deviations a data point is from the mean.

Using a standard normal distribution table or a calculator, we can find the z-score that corresponds to the top 12.3 percent.

The z-score is approximately 1.17.

Next, we can use the formula for z-score conversion to find the corresponding score value:

z = (x - μ) / σ

Rearranging the formula to solve for x (the score):

x = z * σ + μ

Plugging in the values:

x = 1.17 * 18 + 65

x ≈ 86.06

Therefore, the minimum score needed to receive a grade of A is approximately 86.06.

To graph the equations y = x + 2 and y = (1/2)(x + 3)(x - 5), we can start by recognizing that the first equation represents a straight line with a slope of 1 and a y-intercept of 2. This means that for every unit increase in x, y will increase by 1.

The second equation represents a quadratic equation in the form of a parabola. We can determine the shape of the parabola by analyzing the coefficients. In this case, the coefficient of x^2 is positive (1/2), indicating that the parabola opens upward. The x-intercepts can be found by setting y = 0 and solving for x, giving us x = -3 and x = 5.

To find the solution to the system, we need to identify the points of intersection between the line and the parabola. These points will represent the x and y values that satisfy both equations simultaneously.

To solve for L, we can rearrange the formula as follows: Q - 4K = 5L 400 - 4(20) = 5L 320 = 5L L = 64

Therefore, to produce 400 toys per hour with K = 20, the manufacturer would need 64 units of labor input per hour.

b) Similarly, to find out how much K is needed to produce 500 toys per hour when L is equal to 40, we can use the production function formula: Q = 4K + 5L

Substituting the given values, we get: 500 = 4K + 5(40) 500 = 4K + 200 4K = 300 K = 75

Therefore, to produce 500 toys per hour with L = 40, the manufacturer would need 75 units of capital input per hour.

The distance between successive fourth roots of the complex number √3/2 - 1/2i on the unit circle is 5π/24 units.

To find the distance between successive fourth roots of a complex number on the unit circle, we can use the concept of the angle between the roots. Let's proceed step by step:

The given complex number is √3/2 - 1/2i. This complex number lies on the unit circle because its magnitude is equal to 1.

1. Convert the given complex number to trigonometric form:

  √3/2 - 1/2i = cos(θ) + i*sin(θ)

  By comparing the real and imaginary parts, we can determine the angle θ:

  cos(θ) = √3/2

  sin(θ) = -1/2

  Using the unit circle, we can find that θ = 5π/6 (or 150 degrees). This angle represents the position of the given complex number on the unit circle.

2. Find the angle between successive fourth roots:

  Since we are interested in the fourth roots, we divide the angle θ by 4:

  θ/4 = (5π/6) / 4 = 5π/24

  This angle represents the angular distance between two successive fourth roots on the unit circle.

3. Calculate the distance between the two points:

  To find the distance, we multiply the angular distance by the radius of the unit circle (which is 1):

  Distance = (5π/24) * 1 = 5π/24

  Therefore, the distance between successive fourth roots of the complex number √3/2 - 1/2i on the unit circle is 5π/24 units.
