Answer:

Step-by-step explanation:

The general equation we use for ballistic motion is ...

  \(h(t)=\frac{1}{2}gt^2+v_0t+h_0\)

where g is the acceleration due to gravity, v₀ is the initial upward velocity, and h₀ is the initial height.

The values of g commonly used are -32 ft/s², or -4.9 m/s². Units are consistent when the former is used with velocity in ft/s and height in feet. The latter is used when velocity is in m/s, and height is in meters.

_____

Dwayne throws a ball with an initial velocity of 73 feet/second. Dwayne holds the ball 5 feet off the ground before throwing it. (h = -16t^2 + 73t + 5)

A watermelon falls from a height of 5 feet to splatter on the ground below. (h = -16t^2 + 5)

Marcella shoots a foam dart at a target. She holds the dart gun 1.5 meters off the ground before firing. The dart leaves the gun traveling 73 meters/second. (h = -4.9t^2 + 73t + 1.5)

Greg drops a life raft off the side of a boat 1.5 meters above the water. (h = -4.9t^2 + 1.5)

_____

Additional comment on these scenarios

The dart and ball are described as being launched at 73 units per second. Generally, we expect launches of these kinds of objects to have a significant horizontal component. However, these equations are only for vertical motion, so we must assume the launches are straight up (or that the up-directed component of motion is 73 units/second).

The estimated cost of producing the 15th unit is $10.30.

Given the following information about a process that makes high-end boards that get mounted on skateboards:Process starts with a unit cost of $13 for the first unit. Learning rate of LR = 0.90.

Solution :Let's use the learning curve formula to calculate the estimated cost of producing the 15th unit.C = a * N^b .Where:

C = cost per unit ,N = cumulative production volume, a = the unit cost of the first unit, b = log(LR) / log(2) = log(0.90) / log(2) = -0.152N = 15a = 13 (given)

Now, b = -0.152

Therefore ,C = 13 * (15)^(-0.152)C = 13 * 0.789C = 10.3 dollars.

She will have run a total of 2.25 racers in 27 racers

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

Total number of racers = 27 racers

Number of racers in a run = 12 racers

From the above parameter, we can calculate the total number of racers using the following equation

The total number of racers is calculated as

Total number of racers in the run = Total number of racers/Number of racers in a run

Substitute the known values in the above equation

So, we have the following equation

Total number of racers in the run = 27/12

Evaluate the quotient

Total number of racers in the run = 2.25

Hence, the total number of racers in the run is 2.25 racers

Step-by-step explanation:

The second term of an infinite geometric series can be determined using the formula for the sum of an infinite geometric series.



In this case, the sum of the series is given as 200 and the common ratio is 0.15. We can use this information to find the second term of the series.

The formula for the sum of an infinite geometric series is S = a / (1 - r), where S is the sum of the series, a is the first term, and r is the common ratio. We are given that the sum of the series is 200 and the common ratio is 0.15.

Substituting these values into the formula, we have 200 = a / (1 - 0.15). Simplifying, we get 200 = a / 0.85. Multiplying both sides by 0.85, we find that a = 170. Therefore, the first term of the series is 170. Since the common ratio is 0.15, the second term of the series can be calculated by multiplying the first term by the common ratio: 170 * 0.15 = 25.5. Hence, the second term of the series is 25.5.

Answer:

{(-20, -3), (-12, -1), (-8, 0), (-4, 1), (4, 3)}

Step-by-step explanation:

Switch x and y in each ordered pair.

The inverse relation of {(-3, -20), (-1, -12), (0, -8), (1, -4), (3, 4)} is

{(-20, -3), (-12, -1), (-8, 0), (-4, 1), (4, 3)}

The derivative of F(x) is \(F'(x) = x^{(1/3)\).

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

To find the derivative of the given function F(x), we will apply the fundamental theorem of calculus and differentiate the integral with respect to x.

Let's compute F'(x):

F(x) = ∫[0 to x] \(t^{(1/3)} dt\)

To differentiate the integral with respect to x, we'll use the Leibniz integral rule:

F'(x) = d/dx ∫[0 to x] \(t^{(1/3)} dt\)

According to the Leibniz integral rule, we have to apply the chain rule to the upper limit of the integral.

\(F'(x) = x^{(1/3)} d(x)/dx - 0^{(1/3)} d(0)/dx\)   [applying the chain rule to the upper limit]

Since the upper limit of the integral is x, the derivative of x with respect to x is 1, and the derivative of 0 with respect to x is 0.

\(F'(x) = x^{(1/3)} (1) - 0^{(1/3)} (0)\)

\(F'(x) = x^{(1/3)\)

Therefore, the derivative of F(x) is \(F'(x) = x^{(1/3)\).

The game is based purely on chance, the moves and decisions made by each player during the game will require strategic thinking and planning.

Russell has the first throw, he will need to roll two dice and hope that the numbers add up to 12.

The probability of rolling a 12 with two dice is relatively low, at only 1/36.

This means that Russell may need to roll several times before he is able to achieve a sum of 12 and begin the game.
Peter, on the other hand, will also have to throw two dice and hope to achieve a sum of 12.

If Russell is unable to roll a 12, Peter will have the opportunity to roll and try to beat Russell's highest sum.
Once the game begins, Russell and Peter will take turns rolling the dice and moving their game pieces around the board.

The outcome of each turn will depend on the numbers rolled on the dice and the rules of the game.
It is important to note that the probability of rolling different numbers with two dice varies.

For example, the probability of rolling a 7 is much higher than the probability of rolling a 2 or a 12.

This means that certain numbers may be more advantageous to roll in the game, depending on the rules and strategies involved.
Overall, the game will be determined by a combination of luck and skill.

The solution to the system of equations x - 2y = -7 and x + 2y = -3 is x = -5 and y = 1.

To solve the system of equations:

Equation 1: x - 2y = -7

Equation 2: x + 2y = -3

We can use the method of elimination to eliminate one variable and solve for the other. In this case, we'll eliminate the variable "x."

Adding Equation 1 and Equation 2 eliminates the "x" term:

(x - 2y) + (x + 2y) = (-7) + (-3)

2x + 0 = -10

2x = -10

x = -10/2

x = -5

Now that we have found the value of "x," we can substitute it back into one of the original equations to solve for "y." Let's substitute it into Equation 1:

-5 - 2y = -7

-2y = -7 + 5

-2y = -2

y = -2/(-2)

y = 1

Therefore, the solution to the system of equations is x = -5 and y = 1. This means that the two equations intersect at the point (-5, 1) on the coordinate plane.

In summary, the solution to the system of equations x - 2y = -7 and x + 2y = -3 is x = -5 and y = 1.

Given:

Given that the radius of the circle is 2 inches.

We need to determine the area of the remaining square.

Area of a square:

Given that each circle has a radius of 2 inches.

Then, the diameter of each circle is 4 inches.

Hence, the side length of the square is 2 × 4 = 8 inches.

The area of the square is given by

\(A=s^2\)

\(A=8^2\)

\(A=64\) \(in^2\)

Thus, the area of the square is 64 square inches.

Area of the four circles:

The area of one circle is given by

\(A=\pi r^2\)

Substituting r = 2, we have;

\(A=4\pi\)

Thus, the area of one circle is 4π in²

The area of 4 circles is 4 × 4π =16π in²

Hence, the area of the 4 circles is 16π in²

Area of the remaining square:

The area of the remaining square is given by

Area = Area of the square - Area of four circles.

Substituting the values, we get;

\(Area=64-16\pi\)

Thus, the area of the remaining square is (64 - 16π) in²

Hence, Option c is the correct answer.
