A rhombus is one type of parallelogram and has 4 sides and 4 vertices.

Every side is equal in length and opposite angles are equal.

Quadrilateral HGFJ is a rhombus.

GF=16 cm and m∠GHK=42°.

The diagonals of the rhombus bisect each other at the right angle.

Answer:

The answer is D.

Step-by-step explanation:

The correct answer is h(t) = 14.25 + 0.25 * sin((π/26) * t)

To model the hours of daylight in a year using a sinusoidal equation, we can consider the average length of daylight, the amplitude of the variation, and the period of the function.

Given:

Summer solstice (longest day) is 14.5 hours

Winter solstice (longest night) is 14 hours

Let's analyze the information:

Average daylight: The average daylight throughout the year would be the average of the summer and winter solstices. It can be calculated as:

Average daylight = (14.5 + 14) / 2 = 14.25 hours

Amplitude: The difference between the average daylight and the longest day or night is the amplitude. In this case, the amplitude is half the difference between the summer and winter solstices. It can be calculated as:

Amplitude = (14.5 - 14) / 2 = 0.25 hours

Period: We are modeling the function over a year, which we'll consider as 52 weeks. Since we want to measure time in weeks (t), the period of the function is 52 weeks.

Putting all the information together, we can write the sinusoidal equation:

h(t) = Average daylight + Amplitude * sin((2π / Period) * t)

Substituting the values we calculated:

h(t) = 14.25 + 0.25 * sin((2π / 52) * t)

Simplifying further, the sinusoidal equation modeling the hours of daylight in a year is:

h(t) = 14.25 + 0.25 * sin(π/26 * t)

Answer:

To find the dependent value for the graph y = 20 - 2x when the independent value is 5, we substitute x = 5 into the equation and solve for y.

y = 20 - 2x

y = 20 - 2(5)

y = 20 - 10

y = 10

Therefore, when x = 5, the dependent value y is 10.

Answer:

To find the dependent value (y) for the given graph y = 20 - 2x when the independent value (x) is 5, we substitute x = 5 into the equation and solve for y.

y = 20 - 2x

Substituting x = 5:

y = 20 - 2(5)

y = 20 - 10

y = 10

So, when x = 5, the dependent value (y) is 10.

As per the matrix, the value of a, b, c, d are 5, -3. -1, and 2 respectively.

The inverse of a matrix is a matrix that, when multiplied with the original matrix, gives the identity matrix.

To calculate the inverse of a matrix, you first need to find the determinant of the matrix. The determinant is a scalar value that represents the size of the matrix. If the determinant is 0, the matrix is not invertible, meaning that it does not have an inverse.

For the matrix [4 12 1 10], the determinant can be calculated as:

det([4 12 1 10]) = (4 * 10) - (12 * 1) = 40 - 12 = 28

The adjugated of the matrix is:

adj([4 12 1 10]) = [10 -12; -1 4]

Finally, the inverse of the matrix is:

inv([4 12 1 10]) = adj([4 12 1 10]) / det([4 12 1 10])

=> [10 -12; -1 4] / 28

=> [10/28 -12/28; -1/28 4/28]

=>  [5/14 -3/7; -1/28 2/7]

So, the values for a, b, c, and d are 5, -3. -1, 2.

There is no point on the plane 4x + 5y + z = 12 that is nearest to (2, 0, 1).

To find the point on the plane 4x + 5y + z = 12 that is nearest to (2, 0, 1), we can use the concept of orthogonal projection.

First, let's denote the point on the plane as (x, y, z). The vector from this point to (2, 0, 1) can be represented as the vector (2 - x, 0 - y, 1 - z).

Since the point on the plane is on the plane itself, it must satisfy the equation 4x + 5y + z = 12. We can use this equation to find a relationship between x, y, and z.

Substituting the values of x, y, and z into the equation, we have:

4x + 5y + z = 12

4(2 - x) + 5(0 - y) + (1 - z) = 12

Simplifying, we get:

8 - 4x - 5y + 1 - z = 12

9 - 4x - 5y - z = 12

-4x - 5y - z = 3

Now, we have a system of two equations:

4x + 5y + z = 12

-4x - 5y - z = 3

To find the point on the plane nearest to (2, 0, 1), we need to solve this system of equations.

Adding the two equations together, we eliminate the variable z:

(4x + 5y + z) + (-4x - 5y - z) = 12 + 3

Simplifying, we get:

0 = 15

Since 0 = 15 is not true, the system of equations is inconsistent, which means there is no solution.

This implies that there is no point on the plane 4x + 5y + z = 12 that is nearest to (2, 0, 1).

If the lines looks like R--S--T then its 25

Step-by-step explanation:

The value of RS is 55, when ST is 15 and RT is 40 as per the addition operation.

To find the value of RS, we can use the transitive property of equality, which states that if two quantities are equal to a third quantity, then they are equal to each other.

Given that ST = 15 and RT = 40, we can use the transitive property to say that ST + RT = RS.

Substituting the given values, we have 15 + 40 = RS.

Adding 15 and 40, we get RS = 55.

(a)The amount of water in the tank is increasing.

(b)Evaluate  \(\int\limits^{18}_0(W(t) - R(t)) dt\) to get the number of gallons of water in the tank at t = 18.

(c)Solve part (b) to get the absolute minimum from the critical points.

(d)The equation can be set up as   \(\int\limits^k_{18}-R(t) dt = 1200\) and solve this equation to find the value of k.

What is the absolute value of a number?

The absolute value of a number is its distance from zero on the number line. It represents the magnitude or size of a real number without considering its sign.

To solve the given problems, we need to integrate the given rates of water flow to determine the amount of water in the tank at various times. Let's go through each part step by step:

a)To determine if the amount of water in the tank is increasing at time t = 15, we need to compare the rate of water being pumped in with the rate of water being removed.

At t = 15, the rate of water being pumped in is given by \(W(t) = 95Vt sin^2(\frac{t}{6})\) gallons per hour. The rate of water being removed is \(R(t) = 275 sin^2(\frac{1}{3})\) gallons per hour.

Evaluate both rates at t = 15 and compare them. If the rate of water being pumped in is greater than the rate of water being removed, then the amount of water in the tank is increasing. Otherwise, it is decreasing.

b) To find the number of gallons of water in the tank at time t = 18, we need to integrate the net rate of water flow from t = 0 to t = 18. The net rate of water flow is given by the difference between the rate of water being pumped in and the rate of water being removed. So the integral to find the total amount of water in the tank at t = 18 is:

\(\int\limits^{18}_0(W(t) - R(t)) dt\)

Evaluate this integral to get the number of gallons of water in the tank at t = 18.

c)To find the time t when the amount of water in the tank is at an absolute minimum, we need to find the minimum of the function that represents the total amount of water in the tank. The total amount of water in the tank is obtained by integrating the net rate of water flow over the interval [0, 18] as mentioned in part b. Find the critical points and determine the absolute minimum from those points.

d. For t > 18, no water is pumped into the tank, but water continues to be removed at the rate R(t) until the tank becomes empty. To find the value of k, we need to set up an equation involving an integral expression that represents the remaining water in the tank after time t = 18. This equation will represent the condition for the tank to become empty.

The equation can be set up as:

\(\int\limits^k_{18}-R(t) dt = 1200\)

Here, k represents the time at which the tank becomes empty, and the integral represents the cumulative removal of water from t = 18 to t = k. Solve this equation to find the value of k.
