Mark is vacationing out West. He wants to determine the height of a giant saguaro cactus. He stands 90 ft from the cactus so the tip of his shadow meets the tip of the cactus' shadow. If Mark is 6 ft tall and his shadow, s, is 7.0 ft long, what is the height, h, of the cactus? Round your answer to the nearest tenth of a foot if necessary.
Answers
Answer:
The height of cactus is 83.1 feet.
Step-by-step explanation:
Let the height of the cactus be represented by h. Given that the shadows of cactus and Mark meets at the same tip.
Then,
the distance from the cactus to the tip of its shadow = 90 ft + s
= 90 ft + 7 ft
= 97 feet
Thus comparing the two triangles, we have;
\(\frac{h}{6}\) = \(\frac{97}{s}\)
\(\frac{h}{6}\) = \(\frac{97}{7}\)
7 x h = 97 x 6
7h = 582
h = \(\frac{582}{7}\)
= 83.1429
h = 83.1 feet
The height, h, of the cactus is 83.1 feet.
8. if u is uniform on [0,1], find the density function of √u .
Answers
The density function of √u, where u is uniformly distributed on [0,1], is f(v) = 2√v for 0 ≤ v ≤ 1.
To find the density function of √u, where u is uniformly distributed on the interval [0,1], we can use the transformation method.
Let's denote the random variable √u as v = √u. We want to find the probability density function (PDF) of v.
First, we find the cumulative distribution function (CDF) of v:
F(v) = P(v ≤ x) = P(√u ≤ x) = P(u ≤ x²) = x², for 0 ≤ x ≤ 1.
Next, we differentiate the CDF to obtain the PDF of v:
\(\begin{equation}f(v) = \frac{d}{dv} F(v) = \frac{d}{dv} (x^2) = 2x, \quad 0 \leq x \leq 1\)
However, we need to express the PDF in terms of v, not x. Since v = √u, we can substitute x = √v into the PDF:
f(v) = 2√v, for 0 ≤ v ≤ 1.
Therefore, the density function of √u is f(v) = 2√v, for 0 ≤ v ≤ 1.

The answer is (a) $10,000.
How the total cost of producing 200 units of output can be found?The total cost of producing 200 units of output can be found by multiplying the output (200 units) by the average total cost (ATC) per unit, which is given as $50. Therefore, the total cost is:
Total Cost = Output x ATC
Total Cost = 200 x $50
Total Cost = $10,000

this pool measures 7m long by 4m wide and is 1.2 m deep when full. To fill the pool, a hose delivers 20 L per minute is placed in the pool. how long will it take to fill the pool to its proper depth, starting from empty?
Answers
Answer: 28 hours
Step-by-step explanation:
\(V=7(4)(1.2)\\\\v=33.6\ m^3\)
\(\displaystyle\\20\ l/min=\\\\\frac{20(60)}{1000} =\\\\\frac{1200}{1000}=\\\\1.2\ m^3/hour\)
\(\displaystyle\\v=\frac{V}{t} \\\)
Multiply both parts of the equation by t(t≠0):
\(vt=V\)
Divide both parts of the equation by v (v≠0):
\(\displaystyle\\t=\frac{V}{v} \\\\t=\frac{33.6}{1.2} \\\\t=28 \ hours\)
Answer:
We need to find the volume first.
We will use our famous volume of a rectangular solid formula:
V = l x w x h
So, V = 12 x 7 x 1.2 = 100.8 cubic meters.
Now, cost = 100.8 x 27.25 = 2746.8 PHP

Which equation best represents the relationship between x and y in the graph?
Answers
Answer:
C is your correct answer : y = 2x + 3
Step-by-step explanation:
Your answer choices are all in slope-intercept form.
Slope-Intercept Form: y=mx+b
First, you need to find the y-intercept.
Coordinate Point: (0,3) is your y-intercept.
Now, you need to find the slope.
This slope is positive.
There's another point (1,5).
This point is important because you can start at your y-intercept and rise and run to get to (1,5).
You have to rise up 2 and go over to the right 1.
2/1 is your slope but simplified is 2.
Your formula: y = 2x + 3

minimize f(x) = |x+3| + x^3 S.t. x sum [-2, 6]
Answers
Minimization of f(x) = |x+3| + x^3 at the endpoints (-2 and 6) the minimum value of the function is approximately 3.84, which occurs at x= \sqrt{1/3}
within the given interval.
To minimize the function subject to the constraint f(x) = |x+3| + x^3 that x lies in the interval [-2, 6], we need to find the value of x that minimizes f(x) within that interval.
First, let's analyze the function f(x). The absolute value term |x+3| can be rewritten as:
|x+3| =
x+3 if x+3 >= 0
-(x+3) if x+3 < 0
Since the interval [-2, 6] includes both positive and negative values of x+3, we need to consider both cases.
Case 1: x+3 >= 0
In this case, f(x) = (x+3) + x^3 = 2x + x^3 + 3
Case 2: x+3 < 0
In this case, f(x) = -(x+3) + x^3 = -2x + x^3 - 3
Now, we can find the minimum of f(x) within the given interval by evaluating the function at the endpoints (-2 and 6) and at any critical points within the interval.
Calculating the values of f(x) at x = -2, 6, and the critical points, we can determine the minimum value of f(x) and the corresponding value of x.
Since the equation involves both absolute value and a cubic term, it is not possible to find a closed-form solution or an exact minimum value without numerical methods or approximation techniques.

Answers
The expression approximating the CDF P(Y ≤ x) in terms of µ, σ^2, and n is Φ((x - µ)/(σ/√n)), where Φ is the standard normal CDF.
The Central Limit Theorem (CLT) states that for a random sample of size n with a large enough sample size, the sample mean (Y) will be approximately normally distributed with mean µ and variance σ^2/n.
Using this information, we can approximate the cumulative distribution function (CDF) P(Y ≤ x) by transforming it into the standard normal CDF:
P(Y≤ x) ≈ P((Y - µ)/(σ/√n) ≤ (x - µ)/(σ/√n))
Let Z denote the standard normal random variable with mean 0 and variance 1. By standardizing the expression above, we can rewrite it as:
P(Y ≤ x) ≈ P(Z ≤ (x - µ)/(σ/√n))
Finally, we can use the standard normal CDF, denoted as Φ, to approximate the CDF:
P(Y ≤ x) ≈ Φ((x - µ)/(σ/√n))
Therefore, the expression approximating the CDF P(Y ≤ x) in terms of µ, σ^2, and n is Φ((x - µ)/(σ/√n)), where Φ is the standard normal CDF.

Since 4 can be also expressed as 4¹.
