sin(2x) = 2 sin(x) cos(x)

Substituting x = 22.5° into the formula gives:
sin(45°) = 2 sin(22.5°) cos(22.5°)
Dividing both sides by 2 gives:
sin(45°)/2 = sin(22.5°) cos(22.5°)
Substituting the given values into the equation gives:
3 sin(37.5°) cos( 7.5°) = 3 (sin(45°)/2) (cos(45°)/2)
Simplifying gives:
3 sin(37.5°) cos( 7.5°) = 3/4
Therefore, the exact value of the product is 3/4.

19. The exact value of the sum cos (phi/12) - cos (5phi/12) can be determined using the sum-to-product formula for cosine:
cos(x) - cos(y) = -2 sin((x+y)/2) sin((y-x)/2)
Substituting x = phi/12 and y = 5phi/12 into the formula gives:
cos (phi/12) - cos (5phi/12) = -2 sin((phi/12 + 5phi/12)/2) sin((5phi/12 - phi/12)/2)
Simplifying gives:
cos (phi/12) - cos (5phi/12) = -2 sin(3phi/12) sin(2phi/12)
Therefore, the exact value of the sum is -2 sin(3phi/12) sin(2phi/12).

After being rotated 180 degrees anticlockwise around the origin, the picture of the point (4,8) is (-4,-8).

The fixed point is referred to as the rotational centre. The quantity of the rotation is described by the term "angle of rotation," which is measured in degrees. The equivalent of turning a figure 90 degrees anticlockwise is turning it 180 degrees clockwise. Hence, the resulting image of the point is (-1, 2).

Below are the guidelines for rotation: rotation 90 degrees clockwise: (x,y) results in (y,-x) rotation of (x,y) at 90 degrees anticlockwise results in (-y,x) Rotating (x, y) 180 degrees both clockwise and anticlockwise results in (-x,-y).

To find the equation for a line parallel to y = 2x + 1 and passing through the point (1,5), we need to remember that parallel lines have the same slope.

Since the slope of y = 2x + 1 is 2, the slope of the parallel line will also be 2.

Using the point-slope form of a linear equation, we can plug in the given slope and point to find the equation of the parallel line:

y - y1 = m(x - x1)

y - 5 = 2(x - 1)

Simplifying this equation gives us the equation for the parallel line:

y = 2x + 3

So, the equation for the line parallel to y = 2x + 1 and passing through the point (1,5) is y = 2x + 3.

The answer is \(a+b+c+d = 10\).

To find \(a+b+c+d\), we can use matrix multiplication to solve for each variable. Matrix multiplication is performed by multiplying the elements of each row of the first matrix by the corresponding elements of each column of the second matrix, and then summing the products.

So, we can set up the following equations:

\(10 = 1a + 2c\)

\(1 = 1b + 2d\)

\(-6 = 3a - 3c\)

\(-6 = 3b - 3d\)

Solving for each variable, we get:

\(a = 6 - 2c\)

\(b = (1 - 2d)/1\)

\(c = (6 + 3a)/(-3)\)

\(d = (3b + 6)/(-3)\)

Substituting the values of \(a\) and \(b\) into the equations for \(c\) and \(d\), we get:

\(c = (6 + 3(6 - 2c))/(-3)\)

\(d = (3((1 - 2d)/1) + 6)/(-3)\)

Solving for \(c\) and \(d\), we get:

\(c = -2\)

\(d = -1\)

Substituting these values back into the equations for \(a\) and \(b\), we get:

\(a = 6 - 2(-2) = 10\)

\(b = (1 - 2(-1))/1 = 3\)

So, \(a+b+c+d = 10 + 3 + (-2) + (-1) = 10\).

Therefore, the answer is \(a+b+c+d = 10\).

In the given figure by using the alternative angles rule we know that x = 82°.

Alternate angles are a unique type of angle in geometry.

The collection of non-adjacent angles on either side of the transversal is known as alternate angles.

Alternative Interior Angles: Angles are created on the inside, or interior, of two other lines when a third line known as the transversal crosses them. These other lines are typically parallel.

The alternate internal angles are those that are perpendicular to one another.

So, in the given figure:

∠ABD = ∠BDC = 35° (Alternate angles)

Then, ∠DBC will be:

82 + 35 + x = 180

117 + x = 180

x = 180 - 117

x = 63°

Then, ∠DBC = ∠BDA = 63° (Alternate angles)

Now, ∠DAB = 63 + 35 + x = 180

= 63 + 35 + x = 180

= 98 + x = 180

= x = 180 - 98

= x = 82°

Therefore, in the given figure by using the alternative angles rule we know that x = 82°.

Answer: To find the coordinates of D1.5(ABCD), we need to perform a dilation with center D and scale factor 1.5 on the coordinates of each point.

The coordinates of point D are (-5, -10). To dilate point A, we can subtract the coordinates of D from the coordinates of A, multiply by 1.5, and then add the coordinates of D back:

D1.5(A) = 1.5[(2, 0) - (-5, -10)] + (-5, -10) = 1.5(7, 10) + (-5, -10) = (6.5, 5)

Similarly, we can dilate points B and C:

D1.5(B) = 1.5[(8, -4) - (-5, -10)] + (-5, -10) = 1.5(13, 6) + (-5, -10) = (14.5, -4)

D1.5(C) = 1.5[(4, -6) - (-5, -10)] + (-5, -10) = 1.5(9, 4) + (-5, -10) = (7.5, 4)

Therefore, the coordinates of D1.5(ABCD) are A'(6.5, 5), B'(14.5, -4), C'(7.5, 4), and D(-5, -10).

Step-by-step explanation:

The result is the mean of 3.9 miles and median of the team's distances is 3.5 miles.

Mean and median are two ways to measure the center of a set of numbers. Mean is the average of all the numbers in the set, while median is the middle number in the set. Mean is more affected by extreme values, while median is not. Mean is generally used when data is normal, and median when data is skewed.

Mean and median are both measures of central tendency, or measures of the center of a data set. Both measures are used to summarize a data set, but the mean is more affected by outliers, or extreme values, while the median is not.

The mean of the team's distances is 3.9 miles, and the median is 3.5 miles. To calculate the mean, add all the distances together (3.5 + 2.5 + 4 + 3.25 + 3 + 4 + 6) and divide by the number of distances (7). The result is the mean of 3.9 miles. To calculate the median, first order the distances from least to greatest (2.5, 3, 3.25, 3.5, 4, 4, 6) and take the middle number (3.5). The median of the team's distances is 3.5 miles.

The final answer length of the other dimension of the garden is 9x units.

To find the length of the other dimension of the garden, we need to use the formula for the area of a rectangle:

Area = Length x Width

We are given the area and one dimension, so we can plug those values into the formula and solve for the other dimension:

[tex]81x^2-126x[/tex] = (9x-14)(Length)

To solve for the length, we need to divide both sides of the equation by (9x-14):

Length =[tex](81x^2-126x)/(9x-14)[/tex]

Now we can simplify the right side of the equation by factoring out a common factor of 9x:

Length = (9x)(9x-14)/(9x-14)

The (9x-14) terms cancel out, leaving us with:

Length = 9x

So the length of the other dimension of the garden is 9x units.

a) The purchase price of the new equipment is $20,531.76.

b) The amount of interest that will have to be paid is $6,948.24.

The purchase price of the new equipment for New Bread Bakery can be found using the formula for the present value of an annuity:

PV = PMT * [(1 - (1 + i)^(-n)) / i]

Where PV is the present value (or purchase price), PMT is the monthly payment, i is the monthly interest rate, and n is the number of payments.

Plugging in the given values:

PV = 458 * [(1 - (1 + 0.092/12)^(-5*12)) / (0.092/12)]

PV = 458 * [(1 - (1 + 0.00767)^(-60)) / 0.00767]

PV = 458 * [(1 - 0.6887) / 0.00767]

PV = 458 * 40.4624

PV = 18,531.76

The purchase price of the new equipment is $18,531.76. However, this does not include the down payment of $2000. So, the total purchase price is:

PV + Down Payment = 18,531.76 + 2000 = $20,531.76

To find the amount of interest that will have to be paid, we can subtract the purchase price from the total amount paid over the five years:

Interest = (458 * 5 * 12) - 20,531.76 = 27,480 - 20,531.76 = $6,948.24

Therefore, the amount of interest that will have to be paid is $6,948.24.
