The value of θ is 45 degrees as sin45° is equal to 1/√2.

Trigonometric equation refers to an equation consists of a number of trigonometric ratios whose angle is unknown.

Generally trigonometric angles are represented by θ. while solving equations we get the values of θ ranges from 0 degree to 90 degrees.

Given, 2sin²θ = 1

solving the equation

      sin²θ = 1/2

     sinθ = 1/√2

we know sin45° has a specific value 1/√2

   sinθ = sin 45°

now, θ = 45°

hence, the solution is θ = 45 degrees.

If and only if it is odd, a number is the sum of two successive integers.

Only if it is a multiple of 5 is a number considered to be the sum of 5 consecutive integers. If you have any doubts, remember that the product of five consecutive integers equals five times the integer in the middle (this remains true if instead of 5 you put in any odd positive integer).

Consequently, you are seeking odd multiples of 5 below 2017. There are 403 multiples of 5 immediately below 2017, or 2015/5. Of those, 202 are odd.

The sum of the interior angles is calculated using the following angle formula

The sum of the interior angles = ( n − 2 ) × 180 ∘ where n is the number of sides

In this case

n = 9

Substitute the known values in the above equation, so, we have the following representation

The sum of the interior angles = (9 − 2) × 180∘

Evaluate

The sum of the interior angles = 1260∘

So, the internal angle is

Angle = 1260/9

Evaluate

Angle = 140

This means that

5z + 65 = 140

So, we have

What is an angle of a triangle?

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

Given that ∠JKI = (5x−3)⁰, ∠KIJ=(2x+8)⁰, and ∠IJK=(x−1)⁰.

The sum of all angles of a triangle is 180⁰.

(5x−3)⁰ + (2x+8)⁰ + (x−1)⁰ = 180⁰

(5x + 2x + x) + ( - 3 + 8 -1) = 180

8x + 4 = 180

Subtract 4 from both sides:

8x = 176

x = 22

Putting x = 22 in ∠JKI = (5x−3)⁰:

∠JKI = (5×22 − 3)⁰

The linear function that passes through (-8,4) and (4,5) will be y = (1/12)x + 14/3.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

A linear equation or function is given as ;

y = mx + b

The slope (m) associated with two points (x₁, y₁) and (x₂, y₂) is given by

Slope = (y₂ - y₁)/(x₂ - x₁)

The slope associated with (-8,4) and (4,5) will be as,

m = (5 - 4)/(4 + 8) = 1/12

Thus, y = (1/12)x + b

Put (4,5)

5 = (1/12)4 + b

b = 5 - 1/3

b = 14/3

Thus, y = (1/12)x + 14/3

Hence "The linear function that passes through (-8,4) and (4,5) will be y = (1/12)x + 14/3".

Bivariate regression can not demonstrate when the two variables are causally related.

The term variables in math means an alphabet or term that represents an unknown number or unknown value or unknown quantity.

Here we have to find the term that must not demonstrate the bivariate in math.

In order to find the resulting term, we must know the definition of bivariate regression.

The term bivariate regression in statistics is defined as the simple linear regression model which is used to predict one variable referred to as the outcome, criterion, or dependent variable from one other variable referred to as the predictor or independent variable.

Based on these definition we have identified that if the two variables are related then the regression process is not possible.

Given:

Total money Jason and his 3 brothers have = $314,

Each of them will save $17 a week until they have at least $515,

At the end of three weeks, the money saved by Jason and his brothers,

Money saved = 17 × number of person × number of weeks

Assume the number of weeks is x and the money saved is y then,

23.5 days must elapse for a sample of 239np to decay to 0.100% of its original quantity.

Given is the equation for radioactive decay.

N equals N0exp(-λt). We have to determine the λ decay constant.

λ= -(lnN/N0)/t where t = Neptunium-239's half-life, 2.35 days,

and N/N0 = 1/2 where N = Amount of Neptunium-239 after half-life,

and N0 = Amount of Neptunium-239 at the beginning.

Consequently,

λ = (-ln(1/2))/2.35 = 0.294/day.

Neptunium-239 will now degrade to 0.100% of its original value.

N/N₀ × 100 % = 0.100%

N/N₀ = 0.100/100

N/N₀ = 0.001

We calculate the time it takes for Neptunium-239 to decay to this value using the equation for radioactive decay. Making t the formula's subject,

Given:  [tex]\textsf{25 frames per second, starts at 0 seconds already played 190 frames}[/tex]

Find: [tex]\textsf{Frame count already played when time = -3.4}[/tex]

Solution: In order to find the number of frames that have already played when the time was equal to -3.4 seconds, we must first figure out long the delay is.  We can do this by dividing 25 frames per second from 190 frames which gives us that 7.6 seconds passed before we started counting at 0.

Therefore, if we want to look at -3.4 seconds out of -7.6 seconds that means that 4.2 seconds passes after the initial playing to get to -3.4 seconds.  Now we can just multiply 4.2 seconds by 25 frames per second which gives us that about 105 frames have played when the time was equal to -3.4

The stock's average nominal risk premium is 6.70%, while its average real return is 7.47%.

The inflation rate can be obtained from the consumer price index or the GDP deflator. The real rate of return is the actual yearly rate of return after accounting for factors like inflation. It is computed by adding the nominal rate to the inflation rate and dividing the result by three.

The annual return factored in after taxes and inflation is known as the real rate of return. Taxes and inflation are not included in a nominal rate of return, which is what it is called. The same goes for a rate of return that is calculated using taxes or inflation.

From the information given, the average return will be calculated thus:

Average return = 0.540 / 5

                          = 0.108

Average return = 10.80%

Therefore, the average real return will be:

= [( 1 + Average return) / (1+ inflation rate)] - 1

substitute the values in the above equation, we get

= [(1+0.1080) / (1+0.081)] - 1

simplifying the above equation,

= 0.0747

= 7.47%

Also, the average nominal risk premium will be:

= Average Return - Risk free rate

= 0.1080 - 0.041

= 0.067

= 6.70%

Therefore, the stock's average nominal risk premium is 6.70%, while its average real return is 7.47%.
