Qasim spots an airplane on radar that is currently approaching in a straight line, and that will fly directly overhead. The plane maintains a constant altitude of 7200 feet. Qasim initially measures an angle of elevation of 16 ∘ ∘ to the plane at point � A. At some later time, he measures an angle of elevation of 38 ∘ ∘ to the plane at point � B. Find the distance the plane traveled from point � A to point � B. Round your answer to the nearest foot if necessary.
The plane traveled approximately 15,806 feet from point A to point B.
How to solve for the distancetan(angle) = opposite side / adjacent side
Let x be the horizontal distance from Qasim to point A and y be the horizontal distance from Qasim to point B. Then:
tan(16°) = 7200 / x
tan(38°) = 7200 / y
We can solve for x and y:
x = 7200 / tan(16°)
y = 7200 / tan(38°)
Now, we can calculate x and y:
x ≈ 7200 / 0.2878
= 25016.6 feet
y = 7200 / 0.7813
= 9210.7 feet
Finally, to find the distance the plane traveled from point A to point B, we take the difference between y and x:
distance = y - x
= 9210.7 - 25016.6
= -15805.9 feet
we take the absolute value:
distance = 15806 feet (rounded to the nearest foot)
approximately 15,806 feet from point A to point B.

Snow-House sells a $1,248 snow thrower on the installment plan. The installment agreement includes a 20% down payment and 12 monthly payments of $116 each. What is the total cost of the snow thrower on the installment plan?
The total cost of the snow thrower on the installment plan is $1,641.60.
To find the total cost of the snow thrower on the installment plan, we will first calculate the down payment and then add the total monthly payments. Here's the step-by-step explanation:
1. Calculate the down payment:
Down payment = 20% of the original price
Down payment = 0.20 * $1,248
Down payment = $249.60
2. Calculate the total of the 12 monthly payments:
Total monthly payments = 12 * $116
Total monthly payments = $1,392
3. Calculate the total cost on the installment plan:
Total cost = Down payment + Total monthly payments
Total cost = $249.60 + $1,392
Total cost = $1,641.60
So, the total cost of the snow thrower on the installment plan is $1,641.60.

Solve the following inequality, indicate the number of solutions and plot the solutions on a number line.
d. 3(x + 3) + 12 ≤ 3x + 28
Let's start by simplifying the left side of the inequality:
3(x+3) + 12 <= 3x + 28
3x + 9 + 12 <= 3x + 28
3x + 21 <= 3x + 28
Subtracting 3x from both sides, we get:
21 <= 28
This is a true statement, which means that the inequality is true for all values of x. In other words, there are infinitely many solutions.
To represent this graphically, we can draw a number line and shade in all values of x for which the inequality is true. Since it's true for all values of x, we shade in the entire number line:
<=======()------------------->
In this number line, the open circle () indicates that the inequality is not true for that particular value (in this case, there is no specific value for x that makes the inequality false). The arrow indicates that the inequality is true for all values of x to the left and right of the open circle.
In summary, the inequality 3(x+3)+12 <= 3x+28 is true for all values of x, and there are infinitely many solutions.

A rectangular pyramid has a base that is 14 yards long and 14 yards wide. The pyramid's slant height is 12 yards. What is its surface area?
The surface area of the rectangular pyramid is approximately 387.6 square yards.
To find the surface area of a rectangular pyramid, we need to find the area of the base and the area of the four triangular faces.
The area of the base is:
Area of base = length x width
Area of base = 14 yards x 14 yards
Area of base = 196 square yards
To find the area of the four triangular faces, we need to first find the height of each triangle using the Pythagorean theorem.
The Pythagorean theorem states that in a right triangle, the sum of the squares of the legs (the two shorter sides) is equal to the square of the hypotenuse (the longest side).
In this case, the hypotenuse is the slant height of the pyramid, which is 12 yards. The legs are half the length and width of the base, which are both 7 yards.
So we have:
h² + 7² = 12²
h² + 49 = 144
h² = 95
h = √95
Now we can find the area of each triangular face using the formula:
Area of triangle = 1/2 x base x height
The base of each triangle is 14 yards, and the height is √95 yards. So we have:
Area of triangle = 1/2 x 14 yards x √95 yards
Area of triangle = 7√95 square yards
There are four triangular faces, so the total area of the four triangular faces is:
Total area of triangular faces = 4 x 7√95 square yards
Total area of triangular faces = 28√95 square yards
Finally, we can find the total surface area by adding the area of the base and the area of the four triangular faces:
Total surface area = Area of base + Total area of triangular faces
Total surface area = 196 square yards + 28√95 square yards
Total surface area ≈ 387.6 square yards (rounded to one decimal place)

Give the parametric form of the circle x² + y² = 25
x(t) =
y(t) =
This is an exercise in parametric equations, which are a way of representing a curve or surface on the plane or in space using arbitrary values or a constant called a parameter instead of using an independent variable. In the case of circles, the points (x,y) can be expressed from a single variable θ, which is called a parameter. The parametric equations of a circle with radius r ≥ 0 and center (h,k) are given by x = h + rcosθ y = k + rsinθ, where 0 < θ < 2π. The parametric equation of a circle can be expressed from the angle θ of the point through the circle with respect to the x-coordinate axis. The parametric equations of the conics, including the circumference, can be deparameterized to obtain the canonical equation.
The parametric equation of a circle can be expressed from the angle θ of the point through the circle with respect to the x-coordinate axis. The angle can be expressed in radians (θ∈[0,2π]) or sexagesimal degrees (θ∈[0º,360º]). The parametric equation of a circle with center C=(-1,3) and radius r=2 cm is defined by x = -1 + 2cosθ and y = 3 + 2sinθ.
The parametric equations of a curve are expressed from the variable (or parameter) t, such that x = x(t) and y = y(t). Each value of t determines a point (x,y) in the plane. The parametric equations of a circle with radius r ≥ 0 and center (h,k) are given by x = h + rcosθ y = k + rsinθ, where 0 < θ < 2π. The parametric equation of a circle centered at the origin and with radius r is x² + y² = r².
The parametric equations for a curve are not unique. They represent the same circle with center at (0,0) and radius R. The parametric equations of the conics, including the circumference, can be deparameterized to obtain the canonical equation. To go from the parametric to the Cartesian equations, the parameter t must be eliminated. The parametric equations of a point on a circle of radius r at an angle θ are x = rcos(θ) and y = rsin(θ).
To get this parametric form of x² + y² = 25, we can use the trigonometric identities:cos²(t) + sin²(t) = 1
Multiplying both sides by 25, we get:
25 cos²(t) + 25 sin²(t) = 25
Which is equivalent to:
x² + y² = 25
Therefore, we can write:
x(t) = 5 cos(t), y(t) = 5 sin(t)
The parametric form of the circle x² + y² = 25 is:x(t) = 5 cos(t)y(t) = 5 sin(t)This means that for every value of t in the interval 0≤t≤2π, we can get a point on the circle.
Graphic attachedA university class has 27 students: 13 are history majors, 8 are accounting majors, and 6 are art majors. (Each student has only one of these majors.) The professor is planning to select two of the students for a demonstration. The first student will be selected at random, and then the second student will be selected at random from the remaining students. What is the probability that the first student selected is an accounting major and the second student is an art major?
Answer:
8/27
Step-by-step explanation:
There are a total of 27 students in the class, and 8 of them are accounting majors. Therefore, the probability of the first student selected being an accounting major is 8/27.
After the first student is selected, there will be 26 students remaining, out of which 6 are art majors. Therefore, the probability of the second student selected being an art major, given that the first student was an accounting major, is 6/26.
To find the probability of both events occurring together, we need to multiply the individual probabilities:
P(accounting major first) * P(art major second | accounting major first)
= (8/27) * (6/26)
= 48/702
= 8/117

b. Writing the integrand ∫[x/(6x² + 5)²]dx in the form ∫f(u)du, f(u) = u²/12
What is integration?Integration is the reverse of differentiation
a. Since we want to find the substitution in order to evaluate the following integrand ∫[x/(6x² + 5)²]dx, we proceed as follows
In the integrand ∫[x/(6x² + 5)²]dx, we see that the other function is the polynomial in the denominator which is (6x² + 5). So, we make the substitution u = (6x² + 5)
b. To rewrite the integrand in terms of u so that ∫[x/(6x² + 5)²]dx is int he form ∫f(u)du, we proceed as follows
Since integrand ∫[x/(6x² + 5)²]dx and u = 6x² + 5. Differentiation u with respect to x, we have that
du/dx = d(6x² + 5)/dx
= d(6x²)/dx + d5/dx
= 12x + 0
= 12x
So, du/dx = 12x
xdx = du/12
So, substituting this into the integrand, we have that
∫[x/(6x² + 5)²]dx = ∫[x/u²]dx
= ∫[xdx/u²]
= ∫[du/12/u²]
= ∫[du/12u²]
So, comparing ∫[f(u)du] = ∫[du/12u²]

Integration by substitution is a technique used to simplify the integration of complex functions. It involves writing part of the function in terms of a new variable u, where u is some function of x.
Given integral:
[tex]\displaystyle \int \dfrac{x}{(6x^2+5)^5}\; \text{d}x[/tex]
Substitute u for 6x² + 5.
Differentiate u with respect to x and rearrange the equation to isolate dx:
[tex]\dfrac{\text{d}u}{\text{d}x}=12x \implies \text{d}x=\dfrac{1}{12x}\; \text{d}u[/tex]
Substitute the expressions for u and dx into the original expression to rewrite the original integral in terms of u and du:
[tex]\begin{aligned}\displaystyle \int \dfrac{x}{(6x^2+5)^5}\; \text{d}x &= \int \dfrac{x}{u^5} \cdot \dfrac{1}{12x}\; \text{d}u\\\\&= \int \dfrac{1}{12u^5}\; \text{d}u\\\\\end{aligned}[/tex]
Therefore:
[tex]f(u)=\dfrac{1}{12u^5}[/tex]
