The measure of arc ED is 78.7°

An arc of a circle is a portion of the circumference of a circle. It is defined by two endpoints and the arc itself.

The measure of an arc is given in degrees or radians, and it is determined by the angle that it subtends at the center of the circle.

Since FC is the diameter and arc FB is equivalent to arc BC. We can say:

arc FB + arc BC = 180°

arc FB = arc FB = 90°

Also, arc ED is twice the measure of arc CD. We can write:

arc ED = 2 * arc CD

arc CD =  (arc ED)/2

Since the sum arc FB and arc BC is 180°. We can say:

arc FE + arc ED + 0.5(arc ED) = 180°

62° + arc ED + 0.5(arc ED) = 180°

62° + 1.5(arc ED) = 180°

1.5(arc ED) = 180 - 62

1.5(arc ED) = 118

arc ED = 118/3

arc ED =78.7°

Ben's ball lands approximately 2.5 seconds after Andrew's ball.

Since the value of parameter a is -5 for both balls, the height of each ball follows the equation:

h(t) = -5t² + vt + h0

where;

Let's assume that Andrew's ball is hit with an initial velocity of v1, and Ben's ball is hit with an initial velocity of v₂. We also know that Ben's ball reaches a maximum height 50% greater than Andrew's, which means that:

h_max₂ = 1.5h_max₁

At the maximum height, the velocity of the ball is zero, so we can find the time it takes for each ball to reach the maximum height by setting v = 0 in the equation for h(t):

t_max1 = v₁ / (2 x 5)

t_max2 = v₂ / (2 x 5)

Since Ben's ball reaches a maximum height that is 50% greater than Andrew's, we can write:

h_max2 = 1.5h_max1

-5(t_max2)² + v₂t_max2 + h0 = 1.5(-5(t_max1)²   +   v1 * t_max1 + h0)

Simplifying this equation, we get:

-5(t_max2)² + v₂t_max2 = -7.5(t_max1)² + 1.5v₁t_max1

We also know that Andrew's ball lands after 4 seconds, which means that h(4) = 0:

h(4) = -5(4)² + v1 * 4 = 0

-80 + 4v1 = 0

v1 = 80/4

v1 = 20 m/s

Solving these equations for t_max2 and v2, we get:

t_max1 = v1 / (2 x 5)

t_max1 = 20 / (2 x 5)  = 2 s

t_max2 = 1.5 * t_max1 = 3 s

v2 = 1.5 * v1 = 30 m/s

To find the time it takes for Ben's ball to land, we need to find the time t2 when h(t2) = 0.

We can use the equation for h(t) with v = v2, h0 = 0, and solve for t:

-5t² + v₂t = 0

-5t² + 30 = 0

5t² = 30

t² = 30/5

t² = 6

t = √6

t = 2.5 s

Therefore, Ben's ball lands approximately 2.5 seconds after Andrew's ball.

Therefore, the perimeter of the square when its side length is 12 is 48 units.

The perimeter of an object is the space surrounding it. For instance, the yard around your house is fenced in. The perimeter of the barrier is its length. If the yard is 50 by 50 feet, your fence is 200 feet long.

Since a square has all equal sides, the perimeter of a square is just four times the length of one side. Therefore, the perimeter of the square when its side length is 12 is:

Perimeter = 4 x 12 = 48

To write a proportion to solve for the perimeter of a square when its side length is x, we can set up the following ratio:

12/x = 48/p

where p represents the perimeter of the square. We can cross-multiply to get:

12p = 48x

p = 4x

Now we can substitute 12 for x to find the perimeter when the side length is 12:

p = 4(12) = 48

Therefore, the perimeter of the square when its side length is 12 is 48 units.

Step-by-step explanation:

Let the number of students in each van be "x" and the number of students in each bus be "y". We can then set up a system of equations to represent the given information:

From High School A: 8x + 8y = 240

From High School B: 4x + y = 54

We can use the second equation to solve for y in terms of x:

y = 54 - 4x

We can then substitute this expression for y into the first equation and solve for x:

8x + 8(54 - 4x) = 240

8x + 432 - 32x = 240

-24x = -192

x = 8

Now that we know x = 8, we can use the equation for y to solve for y:

y = 54 - 4x = 54 - 4(8) = 22

Therefore, there were 8 students in each van and 22 students in each bus.

The final amount for the investment of $5,000 is $ 6,749.29.

Compound interest is a type of interest calculation in which the interest earned on an initial principal amount is added to the principal, and the new total amount earns interest in subsequent periods.

This means that the interest earned in each period is based on the total amount, which includes both the principal and the accumulated interest from previous periods.

The formula used for compound interest:  

Where:

P = Initial investment

r = Rate of interest (as a decimal)

n = Number of compounds

t = Time period in years

Here we have

P = $5,000,

r = 6% = 0.06,

n = 4 (since the interest is compounded quarterly), and

t = 5 years.  

Using the above formula

The value of r is approximately 0.62.

The sum of the first 3 terms of a geometric sequence is 30 1/2 and the sum of the 4th, 5th, and 6th term is 3 15/16. To determine the value of r, we can use the formula for the sum of a geometric sequence:

S_n = a_1 (1 - r^n) / (1 - r)

Where S_n is the sum of the first n terms, a_1 is the first term, and r is the common ratio.

For the first 3 terms, we have:

30 1/2 = a_1 (1 - r^3) / (1 - r)

For the 4th, 5th, and 6th terms, we can use the formula for the nth term of a geometric sequence:

a_n = a_1 r^(n-1)

So the 4th term is a_1 r^3, the 5th term is a_1 r^4, and the 6th term is a_1 r^5. The sum of these terms is:

3 15/16 = a_1 r^3 + a_1 r^4 + a_1 r^5

We can factor out a_1 r^3 to get:

3 15/16 = a_1 r^3 (1 + r + r^2)

Now we can substitute the expression for a_1 r^3 from the first equation into the second equation:

3 15/16 = (30 1/2) (1 - r) (1 + r + r^2)

Simplifying and rearranging terms, we get:

r^5 - 8r^4 + 15r^3 - 8r^2 + r = 0

This is a quintic equation, which cannot be solved algebraically. However, we can use numerical methods to find an approximate value of r. Using a graphing calculator, we find that r ≈ 0.62.

Therefore, the value of r is approximately 0.62.

What is circle ?

A circle is a shape in geometry that is defined as a closed curve that is formed by a set of points that are equidistant from a single fixed point called the center. The distance between any point on the circle and the center is called the radius of the circle.

The center of the circle appears to be at the point (2, -1) and the radius seems to be approximately 3 units.

Using the values of the center and radius, we can plug them into the general equation of a circle to obtain the equation that represents the circle:

Standard Deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists. The standard deviation indicates a “typical” deviation from the mean. It is a popular measure of variability because it returns to the original units of measure of the data set.

Like the variance, if the data points are close to the mean, there is a small variation whereas the data points are highly spread out from the mean, then it has a high variance.

Its direction is south of east which is 49.56° east of south, the answer is not listed among the answer choices provided.

Magnitude refers to the size or amount of something, often measured numerically or on a scale. In mathematics, it is commonly used to describe the absolute value of a number or the length of a vector in a geometric space. Magnitude can also be used to describe the intensity or strength of physical phenomena, such as the magnitude of an earthquake or the magnitude of a force.

To find the magnitude and direction of MN with tail and head points M(-3, -2) and N(4, 0), we can use the distance formula and trigonometry.

First, we can find the coordinates of MN by subtracting the coordinates of M from those of N:

MN = (4 - (-3), 0 - (-2)) = (7, 2)

The magnitude of MN is the distance between M and N, which can be found using the distance formula:

|MN| = √((7 - (-3))² + (2 - (-2))²) = √(10² + 4²) = √116 ≈ 10.77

Next, we can find the direction of MN by using trigonometry. The angle between MN and the positive x-axis (east) is:

θ = arctan(2/7) ≈ 16.26°

The direction of MN is 180° + θ (measured counterclockwise from the positive x-axis) because the tail point M is to the left of the head point N:

Direction of MN = 180° + 16.26° ≈ 196.26°

To convert this direction to a compass direction, we can subtract it from 360° and then divide by 4, rounding to the nearest degree. This gives:

Compass direction of MN = (360° - 196.26°)/4 ≈ 40.44°

Since MN is to the right of the y-axis (north-south), its direction is south of east, which is 90° - 40.44° = 49.56° east of south.

Step-by-step explanation:

The best interpretation of the given information about the value of the company's stocks is that the value of the company's stocks has reached a local minimum at t=5 and is increasing at an increasing rate for 5 ≤ t ≤ 6.

The value of stocks in a certain new startup company is being modeled by the function S(t), where t is in years since the company going public in 2015. The given information about the value of the company's stocks is S′(5)=0 and S′′(t)>0 for 5 ≤ t ≤ 6.

The derivative S′(t) represents the rate of change of the value of the company's stocks with respect to time. Therefore, S′(5)=0 means that the rate of change of the value of the company's stocks at t=5 is zero, or in other words, the value of the company's stocks is not changing at t=5. This indicates that the value of the company's stocks has reached a local maximum or minimum at t=5.

The second derivative S′′(t) represents the rate of change of the first derivative S′(t) with respect to time. Therefore, S′′(t)>0 for 5 ≤ t ≤ 6 means that the rate of change of the first derivative S′(t) is positive for 5 ≤ t ≤ 6, or in other words, the first derivative S′(t) is increasing for 5 ≤ t ≤ 6. This indicates that the value of the company's stocks is increasing at an increasing rate for 5 ≤ t ≤ 6.

the best interpretation of the given information about the value of the company's stocks is that the value of the company's stocks has reached a local minimum at t=5 and is increasing at an increasing rate for 5 ≤ t ≤ 6.
