Using trigonometry we know that the measure for θ is 25.747121° respectively.

The branch of mathematics is concerned with the computation of certain angles and their functions.

There are six widely used angles-related trigonometric functions.

Their respective names and acronyms are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

So, 14.5 meters is the hypotenuse.

6.3 meters on the opposite side

Using trigonometry now:

sin θ = Opposite side / Hypotenuse

Using the provided values, we obtain:

sin θ = 6.3 / 14.5

sin θ = 63/145

Answer: 12 years

Step-by-step explanation:

     We will substitute the given amount after the investment period and then solve for t, the number of years the period was.

     Given:

A = 10,000(1 + 0.043t)

     Substitue:

15,160 = 10,000(1 + 0.043t)

     Distribute:

15,160 = 10,000 + 430t

     Subtract 10,000 from both sides of the equation:

5,160 = 430t

     Divide both sides of the equation by 430:

The tripes can be observed to have the shape of trapezoids, the middle coloured stripe can be split into two smaller trapezoids while the top and bottom coloured are of same size.

Red and blue portions:

1/2 × (3.5 + 4.5) × 0.6 = 2.4 ft² {area of trapezoid}

top

top and bottom coloured stripe = 2 × 2.4 ft² = 4.8 ft²

The diameter of the circle is 4 inches.

The diameter of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circumference of the circle.

The area of the circle is 12.6 inches square. Let's find the diameter of the circle as follows:

area of a circle = πr²

area of a circle = π(d / 2)²

where

Therefore,

12.6 = 3.14 × d² / 4

12.6 = 0.785d²

divide both sides by 0.785

d² = 12.6 / 0.785

d = √16.050955414

The speed of P when t = 3 seconds is  95.00 m/s

We can find the speed by finding the net force acting on the particle P. Let F_net be the net force acting on P, then we have:

F_net = F₁ + F₂

where:

F₁ = (-i + 2j)N

F₂ = the direction of the vector (i + j).

Let's find the magnitude and direction of F₂. We know that F_net is in the direction of the vector (i + 3j), so we can write:

F_net = F₂ + k(i + 3j)

where:

k = some constant. Since F₂ is in the direction of (i + j), we can write:

F₂ = a(i + j)

where:

a = constant.

Substituting the into the equation for F_net:

F_net = a(i + j) + k(i + 3j)

To find the values of a and k, we use the acceleration of P which is (31 + 9j) m/s². The net force on P is:

F_net = m*a

where m = the mass of P.

Equating the two expressions for F_net:

a(i + j) + k(i + 3j) = m(31 + 9j)

Expanding both sides:

(ai + aj) + (ki + 3kj) = 31m + 9mj

Equating the coefficients of i and j, we get two equations:

a + k = 31m (1)

a + 3k = 9m (2)

Solving these equations:

a = 9m

k = 22m

Substituting these values back into the expression for F_net, we have:

F_net = 9m(i + j) + 22m(i + 3j) = 31mi + 69mj

Now, we can use the equation for acceleration to find the mass of P:

F_net = m*a

31mi + 69mj = m(31 + 9j)

m = 31 / (31 + 9j) = 31 / (31 - 9i)

Next, we shall use the initial velocity and acceleration to find the velocity of P after 3 seconds.

Let v(t) be the velocity of P at time t, then:

v(t) = v(0) + a*t

where v(0) = 3i - 22j and

a = (31 + 9j) m/s²

Substituting t = 3 seconds:

v(3) = (3i - 22j) + (31 + 9j)(3)

= 96i - 1j

Therefore, the speed of P at t = 3 seconds is the magnitude of v(3):

v(3)| = ([tex]\sqrt{96^{2} }[/tex] + (-1)²) = [tex]\sqrt9217[/tex] = 95.00 m/s

The equation of the oblique asymptote of g(x) = x²+x+4/x-1 is y=x+1.

Synthetic division is a shorthand method for dividing polynomials. It is similar to long division, but simplified by removing all the steps except for the division, such as a linear factor with a leading coefficient of one.

To find the equation of the oblique asymptote, we need to divide the numerator (x²+x+4) by the denominator (x-1) using synthetic division.

To do this, we must first create a synthetic division setup, as shown above. The first number in the setup is the number that is being divided by the polynomial in the denominator.

In this case, it is 1. The other numbers in the setup are the coefficients of the polynomial in the numerator.

The synthetic division setup has 1 as the number being divided and 1, 1, and 4 as the coefficients of the numerator.

After dividing, the quotient is x+1 and the remainder is 0. Since the remainder is 0, the equation of the oblique asymptote is y = x+1.

This means that the line with the equation y = x+1 is the oblique asymptote of g(x) = x²+x+4/x-1.

How to find the two transformations applied to pentagon ABCDE to create A″B″C″D″E″?

To find the two transformations applied to pentagon ABCDE to create A″B″C″D″E″, we can compare the coordinates of corresponding vertices of both pentagons.

Starting with point A, we see that it has been translated 8 units to the right and 2 units up to become A″. Therefore, the first transformation is a translation according to the rule (x, y) → (x + 8, y + 2).

Next, we can compare the y-coordinates of point A and A″ to see if a reflection has been applied. We see that the y-coordinate of A has changed from 5 to -7 in A″, indicating that a reflection has been applied across the x-axis.

Therefore, the two transformations applied to pentagon ABCDE to create A″B″C″D″E″ are:

The average speed at which the canoe traveled toward the lighthouse was approximately 14.1 feet per minute.

We can solve this problem using trigonometry. Let's call the distance between the canoe and the lighthouse "x", and let's call the average speed of the canoe "s".

From the first measurement, we know that:

tan(6.5°) = (115 - 1.3) / x

x = (115 - 1.3) / tan(6.5°)

x ≈ 1012.6 feet

From the second measurement, we know that:

tan(48.7°) = (115 - 1.3) / (x - 5/60 * s)

x - 5/60 * s = (115 - 1.3) / tan(48.7°)

x ≈ 166.2 feet

Now we can use these two equations to solve for "s". We can start by solving the second equation for "x" and substituting the result into the first equation:

x = 5/60 * s + (115 - 1.3) / tan(48.7°)

x ≈ 5/60 * s + 80.2 feet

(115 - 1.3) / x = tan(6.5°)

x = (115 - 1.3) / tan(6.5°)

Substituting the first equation into the second equation and simplifying, we get:

5/60 * s + 80.2 = (115 - 1.3) / tan(6.5°)

To find the perimeter of the classroom, we need to calculate the distance between each pair of adjacent corners and add them up.

Using the distance formula, the distance between the first two corners is:

√[(-12 - (-12))^2 + (15 - (-9))^2] = √(0^2 + 24^2) = 24 feet

The distance between the second and third corners is:

√[(-12 - 9)^2 + (-9 - 15)^2] = √(21^2 + 24^2) ≈ 31.8 feet

The distance between the third and fourth corners is:

√[(9 - 9)^2 + (15 - (-9))^2] = √(0^2 + 24^2) = 24 feet

Finally, the distance between the fourth and first corners is:

√[(9 - (-12))^2 + (-9 - 15)^2] = √(21^2 + 24^2) ≈ 31.8 feet

Therefore, the perimeter of the classroom is:

24 + 31.8 + 24 + 31.8 = 111.6 feet ≈ 112 feet (rounded to the nearest foot)
