You could design a solar panel.
Step-by-step explanation:
Nature uses sunlight to grow and provide food for animals, but it only uses what it needs. And it forms a function. So by designing a solar panel, you imitate the way nature works. Solar panels only soak in sunlight for energy when it needs it, which is a function that provides electricity.
(What the question is asking is that you design a product in which some of the aspects listed would be imitated)

12. Lucy has a bag of Skittles with 3 cherry, 5 lime, 4 grape, and 8 orange
Skittles remaining. She chooses a Skittle, eats it, and then chooses
another. What is the probability she get cherry and then lime?
Answers
The probability that Lucy selects a cherry Skittle followed by a lime Skittle is 15/380.
To determine the probability that Lucy selects a cherry Skittle followed by a lime Skittle, we need to consider the total number of Skittles available and the number of cherry and lime Skittles remaining.
Let's calculate the probability step by step:
Step 1: Calculate the probability of selecting a cherry Skittle first.
Lucy has a total of 3 cherry Skittles remaining out of a total of 3 + 5 + 4 + 8 = 20 Skittles remaining.
The probability of selecting a cherry Skittle first is 3/20.
Step 2: Calculate the probability of selecting a lime Skittle second.
After Lucy has eaten the cherry Skittle, she has 2 cherry Skittles remaining, along with 5 lime Skittles out of a total of 19 Skittles remaining.
The probability of selecting a lime Skittle second is 5/19.
Step 3: Calculate the probability of selecting cherry and then lime.
To calculate the probability of two independent events occurring in sequence, we multiply their individual probabilities.
Therefore, the probability of selecting a cherry Skittle first and then a lime Skittle is (3/20) * (5/19) = 15/380.

Just letter b) please
Answers
a) When Bryony throws an ordinary fair 6-sided dice once, the probability of getting a 1 is 1 out of 6, since there is only one face with a 1 out of the six possible outcomes. Therefore, the probability is 1/6 or approximately 0.1667.
b) If Trevor throws the same dice twice, the probability of getting a 1 on both throws is the product of the probabilities of getting a 1 on each throw. Since each throw is independent, the probability of getting a 1 on the first throw is 1/6, and the probability of getting a 1 on the second throw is also 1/6. Therefore, the probability of getting a 1 on both throws is (1/6) * (1/6) = 1/36 or approximately 0.0278.

The tree is ___ meters high. Round your answer to the nearest tenth and write it as a decimal.
Answers
The height of the tree is 1.9 meters
How to determine the height of the treeFrom the question, we have the following parameters that can be used in our computation:
Nova stands at the tip of Caden’s shadow. Caden is 1.2 meters tallCaden's distance from Nova is 4.2 metersCaden's distance from the tree is 6.5 metersThe height of the tree can then be calculated using the following ratio expression
Tree's height : Caden's height = Caden's distance from the tree : Caden's distance from Nova
Substitute the known values in the above equation, so, we have the following representation
Tree's height : 1.2 = 6.5 : 4.2
Express as fraction
Tree's height/1.2 = 6.5/4.2
So, we have
Tree's height = 1.2 * 6.5/4.2
Evaluate

Find a root of an equation f(x)=x³-3x-1 between -1 and 1, using False Position method, after the second iteration.
Answers
The root of the equation \(\(f(x) = x^3 - 3x - 1\)\) between -1 and 1, after the second iteration of the False Position method, is approximately -1.
How to find the root of the equation \(\(f(x) = x^3 - 3x - 1\)\)The False Position method involves finding the x-value that corresponds to the x-intercept of the line passing through \(\((a, f(a))\)\) and \(\((b, f(b))\),\)where (a) and (b) are the endpoints of the interval.
Let's begin the iterations:
Iteration 1:
\(\(a = -1\), \(f(a) = (-1)^3 - 3(-1) - 1 = -3\)\)
\(\(b = 1\), \(f(b) = (1)^3 - 3(1) - 1 = -3\)\)
The line passing through (-1, -3) and (1, -3) is (y = -3). The x-intercept of this line is at (x = 0).
Therefore, the new interval becomes [0, 1] since the sign of f(x) changes between\(\(x = -1\) and \(x = 0\).\)
Iteration 2:
\(\(a = 0\), \(f(a) = (0)^3 - 3(0) - 1 = -1\)\)
\(\(b = 1\), \(f(b) = (1)^3 - 3(1) - 1 = -2\)\)
The line passing through\(\((0, -1)\) and \((1, -2)\) is \(y = -x - 1\)\). The x-intercept of this line is at (x = -1).
After the second iteration, the new interval becomes [-1, 1] since the sign of f(x) changes between (x = 0) and (x = -1).
Therefore, the root of the equation \(\(f(x) = x^3 - 3x - 1\)\) between -1 and 1, after the second iteration of the False Position method, is approximately -1.

The partial sum 1 + 10 + 19 +.... 199 equals :___________
Answers
The partial sum of the given sequence, 1 + 10 + 19 + ... + 199, can be found by identifying the pattern and using the formula for the sum of an arithmetic series. Hence, the partial sum of the sequence 1 + 10 + 19 + ... + 199 equals 4497.
To find the partial sum of the given sequence, we can observe the pattern in the terms. Each term is obtained by adding 9 to the previous term. This indicates that the common difference between consecutive terms is 9.
The formula for the sum of an arithmetic series is Sₙ = (n/2)(a + l), where Sₙ is the sum of the first n terms, a is the first term, and l is the last term.
In this case, the first term a is 1, and we need to find the value of l. Since each term is obtained by adding 9 to the previous term, we can determine l by solving the equation 1 + (n-1) * 9 = 199.
By solving this equation, we find that n = 23, and the last term l = 199.
Substituting the values into the formula for the partial sum, we have:
S₂₃ = (23/2)(1 + 199),
= 23 * 200,
= 4600.
However, this sum includes the terms beyond 199. Since we are interested in the partial sum up to 199, we need to subtract the excess terms.
The excess terms can be calculated by finding the sum of the terms beyond 199, which is (23/2)(9) = 103.5.
Therefore, the partial sum of the given sequence is 4600 - 103.5 = 4496.5, or approximately 4497 when rounded.
Hence, the partial sum of the sequence 1 + 10 + 19 + ... + 199 equals 4497.

Answers
Answer:
Step-by-step explanation:
Victoria used : 170 g of butter for 250 g of flour.
So, 1 g of flour requires = 170/250 g of butter = 0.68 g of butter.
Victoria's daughter used: 340 g butter for 400 g flour
So, 1 g of flour requires = 340/400 g of butter = 0.85 g of butter
Thus, the cookies are not good made by the daughter as the butter is not in appropriate proportion.
Show that the function f(x) f(x) = x3, x < 0 1 x2 sin, x > 0 x is differentiable.
Answers
To show that the function f(x) = x³ for x < 0 and f(x) = x²sin(x) for x > 0 is differentiable, we need to demonstrate that the function has a derivative at every point in its domain.
Let's consider the function f(x) separately for x < 0 and x > 0.
For x < 0
In this case, f(x) = x³. The power rule tells us that the derivative of xⁿ with respect to x is nxⁿ⁻¹. Applying this rule, we find that the derivative of f(x) = x³ is f'(x) = 3x².
For x > 0
In this case, f(x) = x²sin(x). The product rule is used when we have a function that is the product of two other functions. The derivative of f(x) can be calculated as follows
f'(x) = (x²)' sin(x) + x² (sin(x))'
To find the derivative of x² sin(x), we use the product rule again
(f(x)g(x))' = f'(x)g(x) + f(x)g'(x)
Let f(x) = x² and g(x) = sin(x). We have
f'(x) = 2x
g'(x) = cos(x)
Substituting these values back into the product rule equation
f'(x) = (x²)' sin(x) + x² (sin(x))'
= (2x) sin(x) + x^2 cos(x)
Therefore, the derivative of f(x) = x²sin(x) is f'(x) = (2x) sin(x) + x²cos(x).
Now, we have found the derivatives of f(x) for both x < 0 and x > 0. To show that f(x) is differentiable, we need to verify that the derivatives from both cases match at x = 0.
As x approaches 0 from the left side (x < 0), we have
lim(x → 0⁻) f'(x) = lim(x → 0⁻) 3x² = 0
As x approaches 0 from the right side (x > 0), we have
lim(x → 0⁺) f'(x) = lim(x → 0⁺) (2x) sin(x) + x²cos(x) = 0
Since the limits of the derivatives from both cases are equal at x = 0, we can conclude that f(x) = x³ for x < 0 and f(x) = x²sin(x) for x > 0 is differentiable at every point in its domain.

Sub-assembly 1 and component 4 form the final assembly. Following are the work centers and times of each operation. Table Q3(a) shows routine file of the operation. Assuming: - Only one machine is assigned to each operation - The factory works on 8-hour shift, 5 days a week - All parts move in one lot of 200. (a) Illustrate the backward schedule based on the information given above. (12 marks) (b) Identify when component 3 must be started to meet the delivery date. (2 marks)
Answers
Component 3 must be started on day 197 to meet the delivery date of day 200.
To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.
(a) Backward schedule:
Operation | Work Center | Time (hours) | Start Day
--------------------------------------------------------
Final Assembly | Work Center 1 | 1 | 200
Sub-assembly 1 | Work Center 2 | 2 | 199
Component 4 | Work Center 3 | 3 | 197
Component 2 | Work Center 4 | 4 | 196
Component 3 | Work Center 5 | 3 | ????
(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.
From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.
Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.
Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

of money the trainer earned last month?
Answers
Answer: We know that the trainer earns $2,456.75 every month, and she earns an extra $4.75 every time she sells a gym membership.
And last month she sold 32 gym memberships
We can calculate the total amount of money the trainer earned from selling gym memberships by multiplying the number of memberships sold by the amount earned per membership:
32 memberships * $4.75 per membership = $152.00
To find the total amount of money the trainer earned last month, we can add the amount earned from selling gym memberships to the amount earned from her salary:
$2,456.75 + $152.00 = $2,608.75
So, the total amount of money the trainer earned last month is $2,608.75
