given right triangle XYZ what is the value of tan 60°
Answers
Answer:
tan (60) = √3
Explanation:
The given triangle is right-angled triangle, therefore, we will use Pythagorean theorem to get the length of the third side.
third side = sqrt [(hypotenuse)^2 + (second side)^2]
third side = 21√3 units
Since the given triangle is a right-angled triangle, we can apply the special trigonometric identities.
Therefore:
tan θ = opposite / adjacent
In the given triangle:
θ = 60°
The opposite side = 21√3
The adjacent side = 21
Substitute in the above equation to get tan 60 as follows:
tan (60) = (21√3) / (21) = √3

A cable hangs between two poles of equal height and 30 feet apart. set up a coordinate system where the poles are placed at x=−15 and x=15, where x is measured in feet. the height (in feet) of the cable at position x i
Answers
The length of the cable is the number of units on it.
The cable is 35.26 feet long
How to determine the cable lengthThe function is given as:
[tex]h(x) = 15\cos(x/15)[/tex]
For all the lengths, we have the following differential equation
[tex]Length = \int\limits^{15}_{-15} {\sqrt{1 + (\frac{dy}{dx})^2} \, dx[/tex]
So, we have:
[tex]Length = \int\limits^{15}_{-15} {\sqrt{1 + (15 * \frac{1}{15} * \tanh^2(\frac{x}{15}))} \, dx[/tex]
Evaluate
[tex]Length = \int\limits^{15}_{-15} {\sqrt{1 + \tanh^2(\frac{x}{15})} \, dx[/tex]
This gives
[tex]Length = \int\limits^{15}_{-15} {\sqrt{cosh^2(\frac{x}{15})} \, dx[/tex]
Evaluate the exponents
[tex]Length = \int\limits^{15}_{-15} {cosh(\frac{x}{15}) \, dx[/tex]
The above function is an even function.
So, we have:
[tex]Length = 2\int\limits^{15}_{0} {cosh(\frac{x}{15}) \, dx[/tex]
Integrate
[tex]Length = 2 * [\frac{sinh(\frac{x}{15})}{1/15}]|\limits^{15}_{0}[/tex]
Simplify
[tex]Length = 30 * [\sinh(\frac{x}{15})]|\limits^{15}_{0}[/tex]
Expand
[tex]Length = 30 * [\sinh(\frac{15}{15}) - \sinh(\frac{0}{15})][/tex]
Solve
[tex]Length = 35.26[/tex]
Hence, the length of the cable is 35.26 feet

Answers
x P(x)
0 0.2
1 0.4
2 0.4
Total .1.0
i] Expectation
Mean=Σxp
Variance=x²p-(∑xp)²
thus:
Mean=(0*0.2)+(1*0.4)+(2*0.4)
=0+0.4+0.8
=1.2
ii] Variance
Variance=[(0²*0.2)+(1²*0.4)+(2²*0.4)]-(1.2)²
=[0+0.4+1.6]-1.44
=0.56
hence:
standard deviation=sqrt(0.56)=0.74833
The expected number of books a customer will purchase is 1.2 books, and the standard deviation of their book purchases is approximately 0.78 books.
To find the expected number of books a customer will purchase,
use the formula for the expected value (also known as the mean) of a random variable:
Expected Value (μ) = Σ (x × P(x))
Where:
μ is the expected value.
x represents the possible values of the random variable (in this case, 0, 1, and 2).
P(x) is the probability associated with each value of x.
Probability of purchasing 0 books (P(0)) = 0.2
Probability of purchasing 1 book (P(1)) = 0.4
Probability of purchasing 2 books (P(2)) = 0.4
Now, calculate the expected value:
μ = (0 × 0.2) + (1 ×0.4) + (2 × 0.4)
μ = 0 + 0.4 + 0.8
μ = 1.2
To find the standard deviation (σ) of the customer's book purchases,
use the formula for the standard deviation of a discrete random variable:
Standard Deviation (σ) = √[Σ((x - μ)² × P(x))]
Where:
σ is the standard deviation.
x represents the possible values of the random variable.
μ is the expected value.
P(x) is the probability associated with each value of x.
In this case, you already calculated μ as 1.2, and you have the probabilities P(0), P(1), and P(2).
Now, calculate the standard deviation:
σ = √[((0 - 1.2)² × 0.2) + ((1 - 1.2)² × 0.4) + ((2 - 1.2)² × 0.4)]
σ = √[(1.44 ×0.2) + (0.16 × 0.4) + (0.64 × 0.4)]
σ = √[0.288 + 0.064 + 0.256]
σ = √0.608
σ ≈ 0.78
Therefore, the expected number and the standard deviation of books a customer will purchase is 1.2 books and approximately 0.78 books respectively.

Please try this, I forget absolutely everything about rhombuses. Thanks for all the help, shouldn't be too hard
Answers
the volume of a pyramid is, 1/3 ( base area)(height).
well, we know the base is a rhombus, and rhombuses diagonals meet at right-angles, therefore the center O has 4 right-angles where they meet.
since we know the angle at A, 50°, and since rhombuses are quadrilaterals with all equal sides, we know all the sides are 6 long, and the angle at C is 50° as well, and the remaining angles are 130°, as shown there.
now, if we tease out one of those triangles from the rhombus, as shown on the 1st section in the picture, we can say use the angle of 65° to get "x" and "y" lengths
[tex]\bf cos(65^o)=\cfrac{x}{6}\implies 6cos(65^o)=x \\\\\\ sin(65^o)=\cfrac{y}{6}\implies 6sin(65^o)=y[/tex]
now, we'll use those to get the area of the rhombic base.
and then onto the second section
is a right-triangle with a perpendicular line through it, which creates 3 similar triangles, by using the "geometric mean" of "w" there.
anyhow, we used the medium-sized and large-sized triangles there, to draw proportions and get what the "w" distance is, and you can see there what "w" is.
and onto the 3rd section
now that we know how long "w" is, we can use the triangle containing the 40° angle, in order to get the pyramid's height of "h", by using the tangent function, as you see there.
and we also use the same triangle, to get the "z" distance, which is namely the slant-height of the pyramid, however, is also the "altitude" of the triangular faces.
and onto the 4 and last section in the picture
that's a triangular face by herself, it has a base of 6, and an altitude of "z".
now, all that said, let's plug those values to get the volume, and then the surface area, keeping in mind the surface area is just the area of the rhombus plus the area of all four triangles.
[tex]\bf V=\cfrac{1}{3}\left[ \stackrel{\textit{area of the rhombic base}}{4\left( \frac{1}{2}xy \right)} \right](h) \\\\\\ SA=\left[ \stackrel{\textit{area of the rhombic base}}{4\left( \frac{1}{2}xy \right)} \right]~~+~~\left[ \stackrel{\textit{area of the four triangles}}{4\left[ \frac{1}{2}(6)(z) \right]} \right][/tex]
x ≈ 2.54 y ≈ 5.44 w ≈ 2.298 h ≈ 1.93 z = 3
V ≈ 17.7265 SA ≈ 63.58

Solve the inequality and graph its solution: 2t + 1 > 9 or –18 > 5t – 3
Answers
To solve the inequality and graph its solution, solve the two separate inequalities: 2t + 1 > 9 and -18 > 5t - 3. The solution is t > 4 or t < -3.6. Graph the solution by plotting the points 4 and -3.6 on a number line, and shading the area to the right of 4 and the left of -3.6.
Explanation:To solve the inequality and graph its solution, we need to solve the two separate inequalities:
1) 2t + 1 > 9
2) -18 > 5t - 3
For the first inequality, we can subtract 1 from both sides and divide by 2 to obtain t > 4.
For the second inequality, we can add 3 to both sides and divide by 5 to obtain t < -3.6.
Thus, the solution to the original inequality is t > 4 or t < -3.6.
To graph the solution, we would plot the points 4 and -3.6 on a number line, and shade the area to the right of 4 and the left of -3.6.
To solve the inequalities 2t + 1 > 9 and –18 > 5t – 3, we must solve each separately, and since it's an 'or' inequality, we combine the solution sets. The solutions are t > 4 and t < -3. Graphically, these solutions represent non-overlapping shaded regions on a number line.
Explanation:To solve the inequality 2t + 1 > 9 or –18 > 5t – 3, we need to consider them separately as each inequality represents a different solution set.
For the first inequality:
Subtract 1 from both sides to obtain 2t > 8.Divide by 2 to isolate t, yielding t > 4.For the second inequality:
Add 3 to both sides to get –15 > 5t.Divide by 5, which flips the inequality because we are dividing by a positive number, resulting in t < –3.We interpret these results as two separate conditions:
t > 4: This suggests that t is any value greater than 4.t < –3: This suggests that t is any value less than -3.Since the original statement uses 'or', the solution set includes all the values that satisfy either inequality. Therefore, graphically, we would show these on a number line with a shaded region to the right of 4 and another shaded region to the left of -3. The areas do not overlap because there are no t values that can simultaneously be greater than 4 and less than -3.

Answers
An optimization problem seeks to maximize or minimize an objective function, involving endogenous and exogenous variables and is widely used in various fields. Linear optimization uses linear equations and can often be solved with gradient-based techniques in software like MS Excel.
The goal of an optimization problem is to find the maximum or minimum value of a specific function, which is known as the objective function. This function typically represents a scenario such as profit maximization or cost minimization in different fields such as business, economics, and engineering. In an optimization model, there are typically three components: the goal (e.g., maximize profits), the endogenous variables (e.g., the amount of goods produced or the number of hours worked), and the exogenous variables (e.g., price of the goods, wage rates). Linear optimization problems, in particular, represent the objective function and constraints as linear equations and are solved using various mathematical techniques.
Most optimization techniques, such as those used in MS Excel, are gradient-based and offer a systematic approach for finding the optimal solution that either maximizes or minimizes the objective function while satisfying a set of constraints. Whether the objective is to maximize utility or minimize costs, similar approaches can be applied, and sometimes the objective function can be stated in the minimization form in any linear optimization problem by using a transformation.
