(A) Darius is at least 36 inches tall.
(C) William’s height is less than 68 inches.
(F) Darius is no more than 4 inches taller than twice William’s height.
Step-by-step explanation:
edge2022
The inequality w < 68 can be written as William’s height is less than 68 inches.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given that, d ≥ 36, w < 68 and d ≤ 4 + 2w.
Atleast means all probabilities larger than the given probability ('at least') Atmost means all probabilities smaller than the given probability ('at most')
Here, d ≥ 36
Darius is at least 36 inches tall.
w < 68
William’s height is less than 68 inches.
d ≤ 4 + 2w
Darius is no more than 4 inches taller than twice William’s height.
Therefore, the inequality w < 68 can be written as William’s height is less than 68 inches.

if a ferris wheel with radius 180 feet makes 1 full revolution every 8 minutes, what is its linear speed?
Answers
The linear speed is 141.37ft/min.
The relation between the linear speed v and rotational speed (ω) is given by the relation
v=rω.
we know that rotational speed is the speed with which we measure rotations. So
ω=Number of Rotations/Time in minutes.
linear speed:
v=2πrn/T
Linear speed is defined as the wheel would have traveled, had it been rolling on a flat surface.
The given information is the revolution speed of the Ferris wheel as 1 revolution in 8 min.
we can observe that if the wheel rotates one full revolution, the distance that it covers is equal to the circumference of the wheel. In one revolution the distance it travels is
2*π*(180)
distance=1130.9733 ft.
Also, it takes 8 min to complete the distance. so the linear speed is
speed=distance/time
=1130.9733/8
speed=141.37 ft/min.
Hence, the linear speed of the Ferris wheel is 141.37 ft/min.

why is the cartesian coordinate system also called a plane
Answers
The Cartesian coordinate system is also referred to as a plane because it represents a two-dimensional space.
In mathematics, a plane is a flat surface that extends infinitely in all directions. The Cartesian coordinate system consists of two perpendicular lines, known as the x-axis and y-axis, which intersect at a point called the origin. These axes divide the plane into four quadrants.
The term "plane" in the context of the Cartesian coordinate system originates from the concept of a geometric plane, which is a fundamental concept in Euclidean geometry. In Euclidean geometry, a plane is a flat, two-dimensional surface that extends infinitely in all directions.
The Cartesian coordinate system borrows this concept and applies it to represent points, lines, curves, and shapes in a two-dimensional space.
By using the Cartesian coordinate system, we can assign coordinates (x, y) to any point in the plane, where the x-coordinate represents the horizontal position and the y-coordinate represents the vertical position.
This system allows us to precisely locate and describe objects or phenomena within the two-dimensional space, making it a valuable tool in various fields such as mathematics, physics, engineering, and computer graphics.

work out the distance between the two shops
Answers
The actual distance between the two shops is 225 meters.
The map scale of 1 cm: 50 m means that every 1 centimeter on the map represents 50 meters in real life. Using this information, we can calculate the actual distance between the two shops given that the distance on the map is 4.5 centimeters.
To do this, we can use the following formula:
Actual distance = Map distance x Scale
Plugging in the values we have:
Actual distance = 4.5 cm x 50 m/cm
Actual distance = 225 m
It is important to use map scales correctly to accurately represent distances on a map. This can be helpful in many situations, such as planning routes for travel, determining the distance between locations, and estimating travel time. It is also important to note that maps are only representations of reality and may not always be perfectly accurate.

The distribution of retirement age for NFL players is normally distributed with a mean of 33 years old and a standard deviation of about 2 years. What is the percentage of players whose age is less than 31? a 30.85% b 15.87% c 71.2% d 69.15%
Answers
The correct answer is b) 15.87%, indicating that approximately 15.87% of NFL players have a retirement age less than 31 years old.
To find the percentage of players whose age is less than 31, we can use the standard normal distribution and z-scores.
First, we need to calculate the z-score for the value 31 using the formula:
z = (x - μ) / σ
where x is the value we want to find the percentage for, μ is the mean, and σ is the standard deviation.
In this case, x = 31, μ = 33, and σ = 2. Plugging these values into the formula, we get:
z = (31 - 33) / 2 = -1
Next, we can look up the cumulative probability associated with the z-score -1 in the standard normal distribution table. The cumulative probability represents the percentage of values that are less than the given z-score.
From the standard normal distribution table, the cumulative probability for z = -1 is approximately 0.1587, which corresponds to 15.87%.
Therefore, the correct answer is b) 15.87%, indicating that approximately 15.87% of NFL players have a retirement age less than 31 years old.

let R be the region bounded by y=x^2, x=1, y=0. Use the shell method to find the volume of the solid generated when R is revolved about the line y = -4
Answers
The volume of the solid is given by:
V = 2π ∫[0,1] (y + 4) x dy
Using the equation y = x^2, we can express x in terms of y:
x = sqrt(y)
Substituting this into the integral, we get:
V = 2π ∫[0,1] (y + 4) sqrt(y) dy
We can simplify this integral by using u-substitution. Let u = y^(3/2), then du/dy = (3/2) y^(1/2) and dy = (2/3) u^(-2/3) du. Substituting these into the integral, we get:
V = 2π ∫[0,1] (y + 4) sqrt(y) dy
= 2π ∫[0,1] (u^(2/3) + 4) u^(-1/3) (2/3) du
= (4/3)π ∫[0,1] (u^(2/3) + 4) u^(-1/3) du
Integrating, we get:
V = (4/3)π [3u^(5/3)/5 + 12u^(2/3)/2] |_0^1
= (4/3)π [3/5 + 6]
= (22/5)π
Therefore, the volume of the solid generated by revolving R about the line y = -4 is (22/5)π cubic units.

You can leave your answers in square roots.
Answers
Yes, there are diminishing returns to labor in the given production function.
What is the profit-maximizing choice of labor and the resulting output and profit level when the wage rate is 1?
There are diminishing returns to labor in the given production function. As more units of labor (L) are added while holding capital (K) constant, the increase in output (y) becomes smaller and smaller. This is indicative of diminishing marginal product of labor.
When the wage rate (w) is 1 and the capital (K) is fixed at 64, the profit-maximizing choice of labor (L) can be found by equating the marginal product of labor (MPL) to the wage rate. In this case, MPL = 12L^2K.
Setting MPL = w, we have 12L^2K = 1. Substituting K = 64, we get 12L^2 * 64 = 1. Solving for L, we find L ≈ 0.0917.
The profit-maximizing output level (y) can be calculated by substituting the values of L and K into the production function. Thus, y = 4L^3K = 4(0.0917)^3 * 64 ≈ 0.026.
The maximized profit can be determined by subtracting the total cost (TC) from the total revenue (TR). Since the fixed cost is given as 64, TC = 64 + wL = 64 + 1(0.0917) ≈ 64.092. TR is the product of the output level and the price, which is 0.026 * 3 = 0.078.
Profit = TR - TC ≈ 0.078 - 64.092 ≈ -63.014.
Diminishing returns to labor imply that as more labour is employed while holding other factors constant, the incremental increase in output becomes smaller. In the given production function, this phenomenon is observed. In the short run, with a fixed capital level of 64, we determine the profit-maximizing choice of labour (L) when the wage rate (w) is 1. By equating the marginal product of labour (MPL) to the wage rate, we find L ≈ 0.0917. Substituting this value into the production function, we calculate the profit-maximizing output level as y ≈ 0.026. The maximized profit is determined by subtracting the total cost (TC) from the total revenue (TR), resulting in a profit of approximately -63.014. This analysis helps understand the relationship between input choices, output levels, and profit optimization in the short run.

The solution of the given system of equations 8x+3y=5 and 3x-2y=5 is x = 1 and y = -1
In this question we have been given a system of equations.
8x+3y=5 ..........(1)
and 3x-2y=5 ..........(2)
We need to find the solution of the given system of equations.
As right hane side of both equations is equal, we equate LHS of both equations.
so, we get,
8x + 3y = 3x - 2y
⇒ 8x - 3x = - 2y - 3y
⇒ 5x = - 5y
⇒ x = - y .............(3)
By substituting x = - y in equation (1), we get,
8 ( - y ) + 3y = 5
⇒ - 8y + 3y = 5
⇒ - 5y = 5
⇒ y = - 1
Substitute above value of y in equation (3)
⇒ x = - (- 1)
⇒ x = 1
Therefore, x = 1 and y = -1 is solution of given equations.
