fog)oh(x) = fo(goh)x. 3) If f(x) and g(x) are one-one functions, then gof(x) is also one-one function. 4) If f(x) and g(x) are on-to functions, then gof(x) is also on-to function. 5) If f(x) and g(x) are bijective functions, then gof(x) is also a bijective function.

The corresponding point for the transformed function are:

Ordered pair (-4, -9).

Ordered pair (-2, 0).

Ordered pair (1, 12).

Ordered pair (3, 36).

In order to determine the corresponding point for the transformed function, we would have to substitute the given value of x (x-value) into the transformed function and then evaluate.

When the x-value = -4, the corresponding point for the transformed function is:

y = -3f(x + 2)

y = -3f(-4 + 2)

y = -3f(-2)

y = -3(3)

y = -9.

When the x-value = -2, the corresponding point for the transformed function is:

y = -3f(x + 2)

y = -3f(-2 + 2)

y = -3f(0)

y = 0

When the x-value = 1, the corresponding point for the transformed function is:

y = -3f(x + 2)

y = -3f(1 + 2)

y = -3f(3)

y = -3(-4)

y = 12.

When the x-value = 3, the corresponding point for the transformed function is:

Answer:

diving board has a length of 20 feet and a width of 2 feet

Step-by-step explanation:

diving board has a length of 20 feet and a width of 2 feet

Area = length (l) x width (w)

lw = 40

Perimeter = 2l + 2w

we can solve for 'l' and have:

l = 40/w

now substitute 40/w in for 'l' in the perimeter formula to get:

2(40/w) + 2w = 44

distribute through by 2 to get:

80w + 2w² = 44w

we can create the quadratic equation:  2w²-44w + 80 = 0

we can factor out a 2 to get:

2(w² - 22w + 40) = 0

2(w-20)(w-2) = 0

w = 20 and 2

The monthly payment on the principal is $33.22

A monthly payment is a regular installment made by a borrower to a lender in order to pay off a debt over a period of time. It is typically used to repay loans such as mortgages, car loans, or personal loans, and is usually calculated based on the loan's interest rate, principal amount, and loan term (the number of months over which the loan will be repaid).

The formula of monthly payment is given as;

The formula for calculating the monthly payment on a loan is:

M = P * (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

M = monthly payment

P = the principal amount of the loan = $1500

r = the monthly interest rate (expressed as a decimal) = 11.8%

n = the number of payments (in months) = 60 months

The probability of winning, assuming optimal play, is m/n, where m and n are relatively prime integers. Then 100m + n is 11.

To find the probability of winning assuming optimal play, we need to find the probability that we choose the correct box after we know what is in the other box. Let X be the event that the gemstone is in box B1. Then P(X) = 1/10.

After Auntie Hall opens a box, the probability of X changes. Let Y be the event that the opened box contains yoghurt. Then P(Y) = 2/3.

Given Y, the probability of X changes to P(X | Y) = P(X) / (P(X) + P(X complement given Y)). We can use Bayes' theorem:

P(X | Y) = P(Y | X) × P(X) / P(Y)

Since the box that Auntie Hall opens is selected randomly, P(Y | X) = 2/3 for each X complement. Thus,

P(X | Y) = 1/10 × 2/3 / (2/3) = 1/10

The probability of winning is the same regardless of whether we switch boxes or not, so the probability of winning is 1/10.

So, 100m + n = 100 × 1/10 + 1 = 11, and the answer is 100m + n = 100 × 1/10 + 1 = 11.

The arc of length π/6 on the unit circle can be visualized as one-sixth of a full circle with a radius of 1 unit. The unit circle is defined as a circle with a radius of 1 unit centered at the origin (0, 0) in a coordinate plane.

What does the mathematical term "arc" mean?

An "arc" in mathematics is a straight line that connects two endpoints. An arc is typically one of a circle's parts. In essence, it is a portion of a circle's circumference. A curve contains an arc.

To locate the point on the unit circle that corresponds to the end of the arc, we can use the concept of polar coordinates. In polar coordinates, a point on the unit circle is defined by its distance from the origin (r) and its angle with the positive x-axis (θ), as shown in the diagram below.

[diagram here]

For the arc of length π/6 on the unit circle, the angle θ is π/6 and the distance from the origin (r) is 1 unit.

Therefore, the point on the unit circle that corresponds to the end of the arc can be represented in rectangular coordinates as (r * cos(θ), r * sin(θ)), where cos(θ) and sin(θ) are the cosine and sine of the angle θ, respectively.

Substituting the values for r and θ, we have:

x = 1 * cos(π/6) = sqrt(3) / 2

y = 1 * sin(π/6) = 1/2

So, the point on the unit circle that corresponds to the end of the arc of length π/6 is (sqrt(3) / 2, 1/2).

Answer:

In spherical geometry, the sum of the angles of a triangle is always greater than 180 degrees. The formula for this is:

x + y + z > 180 degrees

where x, y, and z are the angles of the triangle.

The formula for the area of a triangle in spherical geometry is given by:

A = R^2 * (θ1 + θ2 + θ3 - π)

Where A is the area of the triangle, R is the radius of the sphere, θ1, θ2, θ3 are the angles of the triangle in radians, and π is the constant pi.

It's important to note that this formula is based on the triangle's spherical excess which is the amount by which the sum of the triangle's angles exceeds 180 degrees.

a) The inequality is,

⇒  x + y + z > 180°

b) Area of spherical ΔXYZ is,

⇒ A = r²  (α + β + у - pi),

where, r is the radius of the sphere and α, β, and y are the angles of the triangle in radians.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Now, the sum of the angles of a triangle is greater than 180 degrees.

Hence, The actual sum of the angles is given by;

x + y + z = π + A,

where A is the area of the triangle measured in radians.

And, As for the formula for the area of a triangle in spherical geometry, it is given by the formula;

⇒ A = r²  (α + β + у - pi),
