The angle 9pi/4 is a positive coterminal angle of pi/4.

What is a coterminal angle?

Two angles are called coterminal if they have the same initial and terminal sides. In other words, two angles are coterminal if they differ by a multiple of 360 degrees or 2π radians. For example, 30 degrees and 390 degrees are coterminal angles, as are π/4 and 9π/4.

A coterminal angle of pi/4 can be found by adding or subtracting any multiple of 2pi until we get an angle between 0 and 2pi that is equivalent to pi/4.

One way to find a positive coterminal angle is to add 2pi:

pi/4 + 2pi = 9pi/4

So, The angle 9pi/4 is a positive coterminal angle of pi/4.

The value of x for which sin(x+16)°=cos(2x+14)° is 20

Trigonometry is a branch of mathematics concerned with relationships between angles and ratios of lengths

The given equation says:

sin(x+16)°=cos(2x+14)°

Remember that sin(90-x) = cos x

Applying this formula we have

So comparing we have,

sin(x+16)°=cos(2x+14)°

90 - (x + 16) = 2x +14

distributing - over the bracket

90 -x - 16 = 2x + 14

bringing like terms together,

90-16-14 = 2x +x

60 = 3x

Dividing both sides by 3,

x =20

Therefore the value of sin(x+16)°=cos(2x+14)° is 20⁰

The volume of the hexagonal prism is 374.13 cubic inches.

The distance from a regular polygon's centre to one of its sides' midpoints is known as the apothem. In other terms, it is the greatest circle whose radius fits inside the polygon. The apothem runs through the middle of the polygon and is perpendicular to the side it touches. All apothems are equivalent in a regular polygon.

For regular polygons, the apothem is a crucial quantity because it is used to determine the polygon's area. The formula: can be used to determine the area of a regular polygon.

A = apothem x perimeter x (1/2)

The volume of the hexagonal prism is given by the formula:

V = B x h

Here, B is the base area thus,

Given the base area = 41.57 sq. in and height = 9 in we have:

V = (41.57)(9) = 374.13 cubic inches.

y = x - 4 is  the equation of the line in slope-intercept form.

How do you interpret a slope-intercept form?

The data provided by that form can be used to graph a linear equation in slope-intercept form. As an illustration, the equation y=2x+3 indicates that the line's slope is 2 and that its y-intercept is located at (0,3). This reveals the single point at which the line passes as well as the direction in which we should draw the full line after that.

If the common ratio is 0.6 then the percent change is 40%

percentage, a relative value indicating hundredth parts of any quantity.

The percent change for a geometric sequence with common ratio r is given by the formula:

percent change = (r - 1) × 100%

In this case, the common ratio is 0.6, so the percent change is:

percent change = (0.6 - 1) × 100% = -0.4 × 100% = -40%

The probability distribution for the number of spins that land on two is given as follows:

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.

Each spinner has a 3/4 probability of not landing on two, hence the probability of landing on two zero times is given as follows:

P(X = 0) = 3/4 x 3/4

P(X = 0) = 9/16

P(X = 0) = 0.5625.

For two times, the probability is given as follows:

P(X = 2) = 1/4 x 1/4

P(X = 2) = 1/16

P(X = 2) = 0.0625.

Hence the probability of one landing is given as follows:

P(X = 1) = 1 - (0.5625 + 0.0625)

P(X = 1) = 0.375.

Part C: the length of each of the five pieces of wood cut by Warren is 3.8 feet.

It is made up of two mathematical objects, with an equals sign (=) between them. Equations are used to represent relationships between unknown variables and can be solved to find their values.

Part A:

The equation that could be used to determine the length of each of the five pieces of wood cut by Warren is: x + 0.7 = 4.5, where x is the length of each piece of wood.

Part B:

The equation from Part A is correct because it takes into account the total length of the wood (4.5 feet), as well as the amount of wood that is left over (0.7 feet).

This equation can be used to calculate how much wood Warren has cut off from the original 4.5 feet of wood, which is the length of each of the five pieces of wood.

Part C:

Solving the equation from Part A:

x + 0.7 = 4.5

Subtract 0.7 from both sides:

x + 0.7 - 0.7 = 4.5 - 0.7

x = 3.8

To find the equation of the line containing the segment DE, we can use the coordinates of D and E to find the slope:

slope = (change in y) / (change in x) = (0 - 3) / (4 - 2) = -3/2

We can use the point-slope form of the equation of a line, using either D or E as the point:

y - 3 = (-3/2)(x - 2)

Simplifying this equation, we get:

y = (-3/2)x + 6

Similarly, to find the equation of the line containing the segment EF, we can find the slope using the coordinates of E and F:

slope = (change in y) / (change in x) = (-2 - 0) / (1 - 4) = 2/3

Using either E or F as the point, we can write the equation in point-slope form:

y - 0 = (2/3)(x - 4)

Simplifying, we get:

y = (2/3)x - (8/3)

To find the equation of the line containing the segment TV, we can find the slope using the coordinates of T and V:

slope = (change in y) / (change in x) = (0 - 3) / (-2 - 0) = 3/2

Using either T or V as the point, we can write the equation in point-slope form:

y - 3 = (3/2)(x - 0)

Simplifying, we get:

y = (3/2)x + 3

Finally, to find the equation of the line containing the segment VW, we can find the slope using the coordinates of V and W:

slope = (change in y) / (change in x) = (-2 - 0) / (1 - (-2)) = -2/3

Using either V or W as the point, we can write the equation in point-slope form:

y - 0 = (-2/3)(x - (-2))

To convert a fraction to a decimal, you need to divide the top number by the bottom number. Here are the steps to follow:

1. Fraction should be written as numerator (top) divided by denominator (bottom).

2. Divide the numerator by the denominator using long division or a calculator.

3. Keep dividing until you get a decimal that terminates or repeats.

a) The given equation is

       [tex]\frac{61}{64} = \frac{29}{64} + x[/tex]

       [tex]\frac{61}{64} - \frac{29}{64} = x[/tex]
