A homeowner would like to spread shredded bark (mulch) over her flowerbeds. She has three flowerbeds measuring 24 ft by 3.1 ft, 14 ft by 4.3 ft, and 30 ft by 1.5 ft. The recommended depth for the mulch is 4 inches, and the shredded bark costs $27 per one cubic yard. How much will it cost to cover all of the flowerbeds with shredded bark? (Note: You cannot buy a portion of a cubic yard of mulch. Assume that there are 27 ft³ in a yd³.)
Answers
If a homeowner would like to spread shredded bark (mulch) over her flowerbeds. it will cost $65.07 to cover all the flowerbeds with shredded bark.
How to find the cost?To calculate the amount of mulch needed, we need to find the volume of each flowerbed and add them together. The recommended depth for the mulch is 4 inches, which is equal to 4/12 = 1/3 feet.
For the first flowerbed, the volume of mulch needed is:
24 ft x 3.1 ft x 1/3 ft = 24.8 cubic feet
For the second flowerbed, the volume of mulch needed is:
14 ft x 4.3 ft x 1/3 ft = 20.87 cubic feet
For the third flowerbed, the volume of mulch needed is:
30 ft x 1.5 ft x 1/3 ft = 15 cubic feet
The total volume of mulch needed to cover all three flowerbeds is:
24.8 cubic feet + 20.87 cubic feet + 15 cubic feet = 60.67 cubic feet
Since there are 27 cubic feet in a cubic yard, the total amount of mulch needed is:
60.67 cubic feet / 27 cubic feet per cubic yard = 2.25 cubic yards
At a cost of $27 per cubic yard, the total cost of the mulch is:
2.25 cubic yards x $27 per cubic yard = $60.75
Therefore, it will cost $60.75 to cover all of the flowerbeds with shredded bark.

Let's roll two dice and find the probability of rolling a certain sum. Is this a simple or compound event?
Two dice - Red and Blue
Recall that a simple event has one and only one outcome of interest. In this example, we are rolling two dice, but we are only interested in one outcome, the sum of the two dice. This is a simple event.
What is the probability of:
Rolling a sum of 1?
Rolling a sum of 3?
Rolling a sum of 12?
Rolling a sum of 7?
Since we are rolling a pair of dice and looking for the sum, the sample space is a little more complicated than rolling one die. The chart below will help us determine the possible outcomes. The top row indicates the numbers on the sides of the blue die and the first column represents the number on the sides of the red die. The white area indicates the sum of the numbers in the row and column.

A plane leaves an airport at noon flying due south at 900 km/h. That same day, another plane is flying due east toward the
airport at 600 km/h.
If the incoming plane is 2000 km away from the airport at 4 pm, what is the rate of change of the distance between the planes?
Answers
The rate of change of the Distance between the planes is zero. This means that the distance between the planes remains constant throughout their respective flights.
The rate of change of the distance between the planes, we need to determine how the distance between them changes over time.
the distance between the two planes is represented by the variable D, and time is represented by the variable t.
At noon, the southbound plane starts flying and continues for 4 hours until 4 pm. During this time, the plane covers a distance of 900 km/h * 4 hours = 3600 km due south.
Meanwhile, the eastbound plane is also traveling towards the airport. It starts from a distance of 2000 km away from the airport at 4 pm.
To find the distance between the planes at any given time, we can use the Pythagorean theorem, as the planes are moving at right angles to each other. The distance D between the planes can be calculated as:
D^2 = (2000 km)^2 + (3600 km)^2
Simplifying the equation:
D^2 = 4000000 km^2 + 12960000 km^2
D^2 = 16960000 km^2
Taking the square root of both sides:
D = sqrt(16960000) km
D = 4120 km
Now, we can find the rate of change of the distance between the planes by calculating the derivative of the distance equation with respect to time
dD/dt = 0
Since the distance between the planes is constant, the rate of change is zero.
Therefore, the rate of change of the distance between the planes is zero. This means that the distance between the planes remains constant throughout their respective flights.

a) The definition of the composite function is: \((f \circ g)(x) = \frac{6}{12 + 2x}\)
b) The domain of the composite function is: (-∞, -6) U (-6, -2) U (-2,0) U (0, ∞).
How to define the composite function of f(x) and g(x)?The composite function of f(x) and g(x) is given by the function rule presented as follows:
(f ∘ g)(x) = f(g(x)).
For the composition of two functions, we have that the output of the inner function, which in this example is given by g(x), serves as the input of the outer function, which in this example is given by f(x).
The functions for this problem are given as follows:
f(x) = x/(x + 2).g(x) = 6/x.Hence the composite function is obtained as follows:
\((f \circ g)(x) = f(\left\frac{6}{x}\right)\)
\((f \circ g)(x) = \frac{\frac{6}{x}}{\frac{6}{x} + 2}\)
\((f \circ g)(x) = \frac{\frac{6}{x}}{\frac{12 + 2x}{x}}\)
\((f \circ g)(x) = \frac{6}{12 + 2x}\)
The domain is all real values except x = 0, x = -2 and x = -6, as f(x) is not defined at x = -2 and g(x) is not defined at x = 0 and the composite function is not defined at x = -6, hence the interval notation is:
(-∞, -6) U (-6, -2) U (-2,0) U (0, ∞).

1Singh R, et al., "Relationship of Collegiate Football Experience and Concussion with Hippocampal Volume and Cognitive Outcomes", JAMA, 311(18), 2014. Data values are estimated from information in the paper. Predict the cognitive percentile for someone who has played football for 11 years and for someone who has played football for 17 years. Enter the exact answers.
Answer:
cognitive percentile for someone who has played football for 11 years = 65.26
cognitive percentile for someone who has played football for 17 years = 45.22
Step-by-step explanation:
This is a very straight forward question. The regression line for predicting percentile from the number of years has been explicitly given in the question as:
Percentile = 102 - 3.34(years)
Therefore,
the cognitive percentile for someone who has played football for 11 years will be calculated as:
Percentile = 102 - 3.34(11)
Percentile = 102 - 36.74
Percentile = 65.26
the cognitive percentile for someone who has played football for 17 years will be calculated as:
Percentile = 102 - 3.34(17)
Percentile = 102 - 56.78
Percentile = 45.22
Instead of handing out candy like a well-adjusted person on Halloween, grumpy, anti-social Professor Sosa decides to stand on top of a 400 ft building and toss candy treats onto the ground below. If he drops a bag of candy corn, how long will it take for it to land on the ground? What will the velocity of the bag be when it hits the ground?
Answers
Answer: The bag of candy corn will take 5 seconds to land on the floor and it will hit it with velocity of 49m/s.
Step-by-step explanation: A free falling object has only Gravitational Force acting on it, so acceleration will be due to gravity, which has magnitude
g = 9.8m/s².
As Professor Sosa drops the bag, its initial velocity and time are 0.
The building has a height of 400ft, so adjusting units: y = 121.92 m and \(y_{0}\) = 0.
For this problem, going down will be the positive reference.
Then:
\(y=y_{0}+v_{0}t+\frac{g}{2}t^{2}\)
\(\Delta y=v_{0}t+\frac{g}{2}t^{2}\)
\(121.92=\frac{9.8}{2}t^{2}\)
\(t=\sqrt{\frac{121.92*2}{9.8} }\)
t ≈ 5
It will take 5s for the candy corn bag to land on the ground.
Acceleration is the change in velocity per change in time, so:
\(g=\frac{\Delta v}{\Delta t}\)
As initial velocity and time are 0 and rearraging it:
v = g.t
v = 9.8*5
v = 49
The bag will hit the ground with velocity of magnitude 49 m/s.
factorise x³-4x²+x+6
Answers
The binomial factors of x³- 4x²+x+6 are (x+2), (x+3), and (x-1).
Using the splitting and grouping the terms:
x³ + 4x² + x - 6
= x³ + 2x² + 2x² + x - 6 [Splitting 4x² = 2x² + 2x²]
= (x³ + 2x²) + (2x² + x - 6)
= x² (x + 2) + (2x² + 4x - 3x - 6)
= x² (x + 2) + [ 2x (x + 2) - 3 (x + 2)]
= x² (x + 2) + (x + 2) (2x - 3)
= (x + 2) ( x² + 2x - 3)
= (x + 2) ( x² + 3x - x - 3)
= (x + 2) [x (x + 3) - 1 (x + 3)]
