An equation for a tangent to the graph of y = arcsin(x/2) at the origin is: A. y = 4x B. x=2y C. y = x D. ax = 2y
Answers
The equation for the tangent to the graph of y = arcsin(x/2) at the origin is y = x. This means that for any given x-value, the corresponding y-value is equal to that x-value, creating a line with a slope of 1. This line is tangent to the graph of y = arcsin(x/2) at the origin, which is (0, 0).
To find the equation for the tangent to the graph of y = arcsin(x/2) at the origin, we must first find the slope at the origin. We can do this by taking the derivative of the function y = arcsin(x/2) with respect to x.
The derivative of
y = arcsin(x/2) with respect to x is y' = (1/2)cos(x/2).
At the origin, x = 0, so the slope of the tangent at the origin is
y' = (1/2)cos(0) = 1.
Therefore, the equation for the tangent to the graph of
y = arcsin(x/2) at the origin is y = x, which has a slope of 1.

Calculate the 95% confidence interval for the following fictional data regarding daily TV viewing habits: µ= 4.7 hours; σ= 1.3 hours; sample of 78 people, with a mean of 4.1 hours.
Answers
We can be 95% confident that the true population mean TV viewing time is between 3.812 and 4.388 hours.
To calculate the 95% confidence interval, we use the formula:
CI = x' ± Zα/2 * (σ/√n)
Where:
x' = sample mean
Zα/2 = the Z-score associated with the desired confidence level (in this case, 95%, so Zα/2 = 1.96)
σ = population standard deviation
n = sample size
Substituting the given values, we get:
CI = 4.1 ± 1.96 * (1.3/√78)
Calculating the standard error (SE) first:
SE = σ/√n
SE = 1.3/√78
SE ≈ 0.147
Then we substitute the SE value in the CI formula:
CI = 4.1 ± 1.96 * 0.147
CI = 4.1 ± 0.288
CI = (3.812, 4.388)

Builtrite has calculated the average cash flow to be $14,000 with a standard deviation of $5000. What is the probability of a cash flow being between than $16,000 and $19,000 ? (Assume a normal distribution.) 16.25% 18.13% 23.90% 2120%
Answers
The correct answer is that the probability of a cash flow being between $16,000 and $19,000 is approximately 18.59%.
To calculate the probability of a cash flow being between $16,000 and $19,000, we can use the standard deviation and assume a normal distribution.
We are given that the average cash flow is $14,000 with a standard deviation of $5,000. These values are necessary to calculate the probability.
The probability of a cash flow falling within a certain range can be determined by converting the values to z-scores, which represent the number of standard deviations away from the mean.
First, we calculate the z-score for $16,000 using the formula: z = (x - μ) / σ, where x is the cash flow value, μ is the mean, and σ is the standard deviation. Plugging in the values, we get z1 = (16,000 - 14,000) / 5,000.
z1 = 2,000 / 5,000 = 0.4.
Next, we calculate the z-score for $19,000: z2 = (19,000 - 14,000) / 5,000.
z2 = 5,000 / 5,000 = 1.
Now that we have the z-scores, we can use a standard normal distribution table or calculator to find the corresponding probabilities.
Subtracting the probability corresponding to the lower z-score from the probability corresponding to the higher z-score will give us the probability of the cash flow falling between $16,000 and $19,000.
Looking up the z-scores in a standard normal distribution table or using a calculator, we find the probability for z1 is 0.6554 and the probability for z2 is 0.8413.
Therefore, the probability of the cash flow being between $16,000 and $19,000 is 0.8413 - 0.6554 = 0.1859, which is approximately 18.59%.
So, the correct answer is that the probability of a cash flow being between $16,000 and $19,000 is approximately 18.59%.

If the retailer's mark up is 30%, and the wholesaler's mark up is 10%, both based on their selling prices, for what price does the manufacturer sell the product to the wholesaler?
Answers
Price Ceiling: A price ceiling is a government-imposed maximum price set below the equilibrium market price.
It is intended to protect consumers by keeping prices low and affordable for certain goods or services.
Price ceilings are often implemented during times of market shortages or to control inflation.
Price Floor: A price floor is a government-imposed minimum price set above the equilibrium market price.
It is intended to protect producers by ensuring they receive a certain level of income for their goods or services.
Price floors are often used in agricultural markets or to establish minimum wage laws.
Value-based Pricing vs. Cost-based Pricing: Both value-based pricing and cost-based pricing approaches have their advantages and disadvantages.
Value-based pricing focuses on determining the perceived value of a product or service to customers and pricing it accordingly.
This approach considers the benefits and value that customers derive from the product and sets the price based on what customers are willing to pay.
Value-based pricing allows for higher profit margins and takes into account customer preferences and willingness to pay.
Cost-based pricing, on the other hand, sets prices based on the production costs and desired profit margin.
It involves calculating the total cost of producing the product and adding a markup to determine the selling price.
Cost-based pricing is more straightforward and easier to implement, as it relies on the actual costs incurred in producing the product.

95 yard
107 yard
160 yard
190 yard
Answers
The amount of fencing needed to surround the perimeter of the picnic area of the park is 107 yards. Hence, the second option is the right choice.
In the question, we are informed that the triangle KLM, represents a section of a park set aside for picnic tables. We are also informed that the picnic area will take up approximately 400 square yards of the park.
We are asked for the amount of fencing needed to surround the perimeter of the picnic area of the park.
We know the area of a triangle can be found using the trigonometric area formula, Area = (1/2)ab sin C.
Using this in the given triangle KLM, we get:
Area = (1/2)(KL)(KM)(sin K),
or, 400 = (1/2)(KL)(45)(sin 25°),
or, KL = (400*2)/(45*sin 25°) = 800/(45*0.42262) = 800/19.017822 = 42.0658 ≈ 42 yd.
Thus, we get KL = 42 yards.
Now, the perimeter of the picnic area = the perimeter of the triangle KLM = KL + LM + MK = 42 + 20 + 45 yards = 107 yards.
Thus, the amount of fencing needed to surround the perimeter of the picnic area of the park is 107 yards. Hence, the second option is the right choice.

-w + 3v + 2u
Answers
To find the resulting vector -w + 3v + 2u, we can calculate each component separately and combine them. The component form of vector -w is (-(-4), -(-1)) = (4, 1). The component form of vector 3v is 3(2, 4) = (6, 12). The component form of vector 2u is 2(-3, 4) = (-6, 8).
Now, we can add the corresponding components of these vectors: (-w + 3v + 2u) = (4, 1) + (6, 12) + (-6, 8) = (4 + 6 - 6, 1 + 12 + 8) = (4, 21). Therefore, the resulting vector in component form is (4, 21). To find the magnitude of the resulting vector, we can use the formula: Magnitude = sqrt(x^2 + y^2), where x and y are the components of the vector. For the resulting vector (4, 21), the magnitude is: Magnitude = sqrt(4^2 + 21^2) = sqrt(16 + 441) = sqrt(457). Hence, the magnitude of the resulting vector -w + 3v + 2u is sqrt(457).

P2 = (0 , -8)
P3 = (2 , -5)
Substitute the points in the expression f(x) = y = ax² + b x + c.
5 = a(-2)² + b(-2) + c ⇒ 5 = 4a - 2b + c (equation 1)
-8 = a(0)² + b(0) + c ⇒ -8 = c (equation 2)
-5 = a(2)² + b(2) + c ⇒ -5 = 4a + 2b + c (equation 3)
Substitute equation 2 in equation 1 and 3.
5 = 4a - 2b + -8 ⇒ 13 = 4a - 2b (equation 4)
-5 = 4a + 2b + -8 ⇒ 3 = 4a + 2b (equation 5)
13 = 4a - 2b (equation 4)
-(3 = 4a + 2b) (equation 5)
10 = -4b
b = -5/2
Substitute the value of b in equation 4.
13 = 4a - 2(-5/2)
4a = 13 - 5
a = 2
If a = 2, b = -5/2 and c = -8, then the quadratic equation should be y = 2x² - 5/2x - 8.
