The value of sin θ from the unit circle is sin θ = 0.9230769

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

Given data ,

The terminal side of angle θ intersects the unit circle in the first quadrant at ( 3√10/10,√10/10 )

So , the equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r²   be equation (1)

Substituting the values of x and y in the equation , we get

x = -5/13

And , y = 12/13

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

So , the value of cos θ = ( -5/13 ) and sin θ = ( 12/13 )

On simplifying the equation , we get

sin θ = ( 12/13 )

sin θ = 0.9230769

Hence , the value of sin θ = 0.9230769

Answer:

Step-by-step explanation:

The equation of the line with the given points is y = 6x - 4. This can be derived by calculating the slope of the line, which is 6, and then using the point-slope form of the equation of a line, y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line. In this case, the given points are (x1, y1) = (1, 10), so the equation of the line is y - 10 = 6(x - 1) or y = 6x - 4.

Answer y == 3

Step-by-step explanation:

The graph of a linear relationship contains the points (1, 10) and (3, 16).

Write the equation of the line in slope-intercept fo

Step-by-step explanation:

the general slope-intercept form is

y = ax + b

a is the slope, which is the ratio of "y coordinate change / x coordinate change" when going from one point to another on the line.

b is the y-intercept - the y value when x = 0.

for the slope we see

x changes by +2 (from 1 to 3)

y changes by +6 (from 10 to 16)

so, the slope a is +6/+2 = 3

and the semi-ready equation is

y = 3x + b.

now we use one of the points in the equation to solve for b. I picked (1, 10) :

10 = 3×1 + b = 3 + b

b = 7

so, the full equation is

y = 3x + 7

From the given figure,

In the given triangle ,

The triangles are 3x - 1 , 8x - 35  and 6x - 5

The sum of all angles is always is 180 degrees.

so,

we get,

3x - 1 + 8x - 35 + 6x - 5 = 180

17x - 41 = 180

17x = 180 + 41

17x = 221

x = 221 / 17

x = 13

so,

3x - 1  = 3*13 - 1 = 38

8x - 35  = 8* 13 - 35 = 104 - 35 = 69

6x - 5 = 6*13 - 5 = 78 - 5 = 73

Answer:

a) GH¢15x

b) GH¢15

Step-by-step explanation:

a) To find the cost function, C(x), given that it is linear, we need to find the slope and y-intercept of the line that represents the cost to produce x units of the product. We can use the point-slope form of a line to find the cost function: C(x) = mx + b, where m is the slope and b is the y-intercept.

We have two points: (100, GH¢1,500) and (0, GH¢0), which represents the cost to produce 100 units and 0 units, respectively. The slope can be found by dividing the change in y by the change in x:

m = (GH¢1,500 - GH¢0) / (100 - 0) = GH¢15

The y-intercept can be found by plugging in one of the points and solving for b:

GH¢1,500 = (GH¢15)(100) + b

GH¢1,500 = GH¢1,500 + b

b = GH¢0

So the cost function is C(x) = GH¢15x + GH¢0.

b) To find the average cost per item to produce 50 units and 300 units, we need to divide the total cost by the number of units produced.

For 50 units:

C(50) = GH¢15 * 50 + GH¢0 = GH¢750

Average cost = C(50) / 50 = GH¢15

For 300 units:

C(300) = GH¢15 * 300 + GH¢0 = GH¢4,500

Average cost = C(300) / 300 = GH¢15

a) The continuous growth rate can be calculated using the formula:

r = (ln(B) - ln(A)) / t

where r is the continuous growth rate, A is the initial count (330), B is the count after 6 hours (1340), and t is the time elapsed (6 hours).

Substituting the values:

r = (ln(1340) - ln(330)) / 6

r = 0.3907

b) The model for the bacteria colony can be written as:

B = A * e^(rt)

where B is the number of bacteria after time t, A is the initial count (330), and e is the base of the natural logarithm.

c) To find the number of bacteria after 16 hours, substitute t = 16 and the values of A and r from above:

B = 330 * e^(0.3907 * 16)

B = 9581.57

The number of bacteria after 16 hours is approximately 9582.

The worker B has a higher variance of σ² = 9 and standard deviation of 3

The standard deviation refers to a measurement of the data dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Standard Deviation is calculated by

Each number's deviation from the mean must be determined, and then squared.

Next, add up all of these values.

Divide the result by the quantity of numbers.

Then calculate its square root.

Given data ,

Let the data of worker A = { 5, 4, 4, 6, 7, 5, 6, 3 }

Let the data of worker B = { 4, 8, 1, 9, 2, 9, 4, 3 }

Now , the mean of worker A = 5

The mean of worker B = 5

So , the standard deviation of worker A is calculated as

On simplifying the equation , we get

SD = √ ( 12/8 )

SD = √1.5

Standard deviation σ = 1.2247449

The inverse function of f(x) = (x^2+1)^2 step by step is given below.

The inverse of f(x) is √(√x - 1).

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = (x² + 1)²

The steps for finding the inverse of a function.

Step 1:

Keep y = f(x)

y = (x² + 1)²

Step 2:

Interchange x and y.

x = (y² + 1)²

Step 3:

Solve for y.

x = (y² + 1)²

Square root on both sides.

√x = y² + 1

(√x - 1) = y²

Square root on both sides.

y = √(√x - 1)
