The initial payment for the first 3 years of an interest-only loan for a $141,000 5/130-year ARM at 5% would be $7050.

An ARM, or Adjustable Rate Mortgage, is a type of mortgage loan where the interest rate can change over time. The 5/1 in the loan term "5/130-year ARM" means that the initial rate is fixed for the first 5 years and can change once every year thereafter for the remaining life of the loan (in this case, 130 years).

For an interest-only loan, the borrower pays only the interest due on the loan for a set period of time, in this case, the first 3 years. The interest payment can be calculated as:

Interest payment = Loan amount * Interest rate

The loan amount in this case is $141,000 and the interest rate is 5%, so the interest payment is:

Interest payment = $141,000 * 0.05 = $7050

So, the initial payment for the first 3 years of an interest-only loan for a $141,000 5/130-year ARM at 5% would be $7050.

Therefore , if we know the measures of the angles θ1 and θ2 in degrees, we can use equations (1) and (2) to find their difference, α - β.

An angle in Euclidean space is a shape made up of two poles that divide at the centre, or apex, of the structure. These beams are referred to as the sides or loops. When two rays are combined, there may be an inclination inside this surfaces where they are situated. Angles can also be created by combining two surface.

Here,

Since the two angles share the same terminal side, they are coterminal angles. This means that they differ by an integer multiple of 360 degrees or 2π radians.

Let the two angles be θ1 and θ2. Then we can express them as:

θ1 = k(360°) + α (1)

θ2 = k(360°) + β (2)

where k is an integer and α and β are the measures of the angles in degrees, such that 0° ≤ α, β < 360°.

Since the angles share the same terminal side, they must add up to 360 degrees or 2π radians. So we have:

θ1 + θ2 = k(360°) + α + k(360°) + β = 360° (3)

Simplifying equation (3), we get:

θ1 + θ2 = 2k(360°) + α + β = 360°

α + β = 360° - 2k(360°) = 360°(1 - 2k)

Therefore, the sum of the two angles α and β is equal to 360 degrees times an integer 1-2k.

To find the difference between the two angles, we can subtract equation (2) from equation (1):

θ1 - θ2 = (k(360°) + α) - (k(360°) + β) = α - β

Therefore, the difference between the two angles is equal to the absolute value of the difference between their measures in degrees:

|α - β| = |θ1 - θ2|

Note that since the angles are coterminal, their measures differ by an integer multiple of 360 degrees, so the difference between their measures can be found by subtracting one from the other and taking the result modulo 360. That is:

α - β = (θ1 - θ2) mod 360°

So if we know the measures of the angles θ1 and θ2 in degrees, we can use equations (1) and (2) to find their difference, α - β.

Hi there, here's your answer.

Given:

A circle with center O.

A, B, C and D lie on the circumference of the circle.

AC is the diameter of the circle.

∠DCA = 33° and ∠BCA = 31°

To find:

∠DAB

Solution:

Since AC is a diameter, ∠CDA and ∠CBA will be equal to 90° (Angles in a semi-circle)

Now, ∠BCD = ∠DCA + ∠BCA

∴ ∠BCD = 33° + 31° = 64°

Now, ∠BCD + ∠CDA + ∠DAB + ∠ ABC = 360° (Angle-sum property of a quadrilateral)

Substituting the values of the angles:

64° + 90° + 90° + ∠DAB = 360°

Or

244° + ∠DAB = 360°

Therefore ∠DAB = 360° - 244° = 116°

Answer:  11/8 ( 1 3/8)

Step-by-step explanation: Look at the attachment below for the best experience. First, before we add we need to find the common denominator of the denominators (2, 4, 8) That'd be 8, because 2, 4, 8 . Look at the explanation for the best view.

The value of sin(x) in terms of cos(x) is √1 - cos²(x). The value of sin(x) is 3/5.

Since x is an angle in the second quadrant, sin(x) is positive and cos(x) is negative.

To write sin(x) in terms of cos(x), we can use the identity sin²(x) + cos²(x) = 1 and solve for sin(x):

                                sin²(x) + cos²(x) = 1

                                sin²(x) = 1 - cos²(x)

                                sin(x) = ± √(1 - cos²(x))

Since sin(x) is positive in the second quadrant, we have:

                               sin(x) = √(1 - cos²(x))

To show that cos(x) = -4/5, we can use the given equation:

                               3sin(x) - 4cos(x) = 5

We can rearrange this equation to get cos(x) on one side:

                              4cos(x) = 3sin(x) - 5

                              cos(x) = (3sin(x) - 5) / 4

Now we can substitute the expression for sin(x) that we found earlier:

                              cos(x) = (3√(1 - cos²(x)) - 5) / 4

Multiplying both sides by 4 and simplifying, we get:

                              4cos²(x) + 3cos(x) - 4 = 0

This is a quadratic equation in cos(x). We can solve it using the quadratic formula:

                             cos(x) = [-3 ± √(3² - 4(4)(-4))] / (2(4))

                             cos(x) = (-3 ± 7) / 8

                             cos(x) = 1/2 or cos(x) = -4/5

Since x is in the second quadrant, we have cos(x) < 0, so cos(x) = -4/5.

Finally, we can use the expression for sin(x) that we found earlier to get:

                            sin(x) = √(1 - cos²(x))

                            sin(x) = √(1 - (-4/5)²)

                            sin(x) = √(1 - 16/25)

                            sin(x) = √9/25

                            sin(x) = 3/5

Therefore, the exact value of sin(x) is 3/5.

The new function, g(x), will be stretched or compressed by a factor of two, making it equivalent to f(2x).

According to the function, every value in the domain is associated to exactly one value in the range, and they have a predefined domain and range. This specific sort of relationship is thus defined.

A function called f(x) is displayed in the coordinate plane.

The formula is g(x) = f. (2x)

It is the transformation of the f, as we can see in the new function g(x) (x).

Applying transformation is done as follows:

x → 2x (x is replaced by the twice of it) (x is replaced by the twice of it)

= f(x) (x)

= f(2x) (2x)

= g(x) (x)

In the given function, the factor is 2, thus the g(x) will be stretched or compressed in accordance with that factor. When the function is multiplied by a positive number, it will be compressed or stretched vertically according to that factor.

Answer:

Sarah purchased 2 first class tickets and 5 coach tickets.

Step-by-step explanation:

Let's call the number of first class tickets purchased "x".

The number of coach tickets purchased would be 7-x.

We know that the total spent on first class tickets was $1170 * x and the total spent on coach tickets was $320 * (7-x).

The total budget was $3940, so we can set up the following equation:

$1170 * x + $320 * (7-x) = $3940

Expanding the right side:

$1170 * x + $320 * 7 - $320 * x = $3940

Combining like terms:

$800 * x = $3940 - $320 * 7

Subtracting $320 * 7 from both sides:

$800 * x = $3940 - $2240

$800 * x = $1700

Dividing both sides by 800:

x = 2.125

Since x must be a whole number, Sarah purchased 2 first class tickets and 5 coach tickets.

Step-by-step explanation:

The inverse of a function switches the roles of x and y, making the original range the new domain and the original domain the new range. In this case, the original domain is x≥7 and the range is y≥−1, so the inverse has a domain of y≥−1 and a range of x≥7 :)

Step 1: Calculate the volume of the water in the first container.

The volume of a cylinder is V = πr^2h, where r is the radius of the cylinder and h is the height of the cylinder.

Therefore, the volume of the water in the first container is V = πr^2 x 15 cm, where r is the given radius of the container.

Step 2: Calculate the height of the water in the second container.

The volume of the water in the second container is the same as the volume of the water in the first container, since the same quantity of water is being poured from one container to the other.

Therefore, the volume of the water in the second container is also V = πr^2 x 15 cm, where r is now 2r, the radius of the second container.

To find the height of the water in the second container, we can substitute the value of the radius into the equation for the volume and solve for h. This gives us h = (15 cm) / (π(2r)^2), which simplifies to h = 15 cm / 4πr^2.
