Sin(pi - theta) has a value of 4/9. sin(pi - theta) is equal to sin for any value of theta (theta). sin(pi - theta) has a value of 4/9.

We may calculate the value of sin(pi - theta) using the trigonometric identity sin(pi - theta) = sin(pi)cos(theta) - cos(pi)sin(theta):

Pi minus theta equals sin (pi)

cos(pi)sin - cos(theta) (theta)

We may simplify the expression to: since sin(pi) = 0 and cos(pi) = -1

0*cos(theta) - (-1)*sin = sin(pi - theta) (theta)

Pi minus theta equals sin (theta)

The value of sin(theta) can now be substituted to obtain:

Theta = 4/9 sin(pi - theta)

Hence, sin(pi - theta) has a value of 4/9.

The value of theta determines the value of sin(pi - theta). In terms of the trigonometric functions of theta, there is a generic formula to get sin(pi - theta): Pi minus theta equals sin (pi)

cos(pi)sin - cos(theta) (theta)

We may simplify the expression to: since sin(pi) = 0 and cos(pi) = -1

0*cos(theta) - (-1)*sin = sin(pi - theta) (theta)

Pi minus theta equals sin (theta)

Hence, sin(pi - theta) is equal to sin for any value of theta (theta).

Hence, sin(pi - theta) has a value of 4/9.

Rotation: Rotate the larger circle by the same angle as the smaller circle around the origin. Rotate the smaller circle by any angle. Although changing direction, this metamorphosis keeps the shape and size intact.

Any point in the plane that is a certain distance from another point forms a circle (center). Thus, it is a curve formed up of points that are separated from one another by a predetermined distance in the plane. Moreover, at every angle, it is rotationally symmetric about the centre. The closed, two-dimensional plane of a circle has every pair of points equally separated from the "centre." By drawing a line through the circle, one can create a line of circular symmetry. Moreover, at every angle, it is rotationally symmetric about the centre.

If two circles have the same shape but different sizes, they are comparable. The circles are centred at the origin in this case, allowing us to compare their radii to see if they are equal. The ratio of the larger and smaller circles' radii is 8/2, or 4.

Translation: Move the smaller circle to the origin and the larger circle in the same direction to a place four times away from the origin. While changing location, this transformation keeps the object's shape and size.

Answer:

To work out the pressure that the car exerts on the road, we need to divide the force by the area of contact between the car and the road.

Since each of the car's 4 tyres has an area of 0.03 m² in contact with the road, the total area of contact is:

Total area of contact = 4 × 0.03 m² = 0.12 m²

So, the pressure that the car exerts on the road can be calculated as:

Pressure = Force / Area of contact

Pressure = 15,600 N / 0.12 m²

Pressure = 130,000 N/m²

Therefore, the pressure that the car exerts on the road is 130,000 N/m².

For given functions f(x) and g(x), the value of  (f °g)(12) is 24.

What exactly is a function?

In mathematics, a function is a rule that assigns to each input value (also called the argument) exactly one output value. The input values are typically drawn from a specific set, called the domain of the function, and the output values are drawn from another set, called the range of the function.

Now,

To find (f °g)(12), we need to first evaluate g(12) and then use the result to evaluate f(g(12)).

g(x) = √(x+4), so g(12) = √(12+4) = √16 = 4.

f(x) = 4x+8, so f(g(12)) = f(4) = 4(4) + 8 = 16 + 8 = 24.

Therefore,

                  The value of (f ° g)(12) = f(g(12)) = 24.

The rule is to minus 4 from the x-coordinate and add 8 to the other. The coordinates of A after the reflection are (-x,y). Thus, it is present to the left of the Y-axis. Yes, the final figure is congruent to the original figure.

To translate a point 4 units left and 8 units up, we subtract 4 from the x-coordinate and add 8 to the y-coordinate.

Now, let’s apply this rule to point A. If A has coordinates (x,y), then after translation it will have coordinates (x-4,y+8).

For the second question, we can find the new location of A by using the coordinates we just found. So if A was originally located at (x,y), it will now be located at (x-4,y+8).

To reflect a point over the y-axis, we negate its x-coordinate. So if A has coordinates (x,y), then after reflection it will have coordinates (-x,y).

Using this rule, we can find that after reflection over y-axis, point A will have coordinates (-x,y).

Finally, since translation and reflection are both rigid transformations, they preserve distance and angles between points. Therefore, the final figure is congruent to the original figure.

The '=' symbol links up the two expressions. A mathematical formula containing two formulas on either side of a =) (=) is known as an equation. It depicts the equivalence relationship between left and right methodologies. L.H.S. = R.H.S. (left edge = top half) in any formula.

Using the information provided, we can construct the following equation based on the concept of similar triangles:

x/(9+18) = 10/(BC) (BC)

9 + 18 = 27 = AB = AP + PB

Because triangle ABC is a right triangle (angle B is 90 degrees), we can apply the Pythagorean theorem to calculate the length of segment BC:

BC2 = AB2 - AC2 BC2 = 272 - 102 BC2 = 649 BC = sqrt (649)

When we plug this value into our original equation, we get:

x/(9+18) = 10/sqrt (649)

When we simplify, we get:

x/27 = 10/sqrt (649)

When we multiply both sides by 27, we get:

Answer:

$6141

Step-by-step explanation:

We can use the formula for compound interest to find the amount in the account after 18 years:

A = P(1 + r/n)^(nt)

Where:

A = the amount in the account after 18 years

P = the principal amount (initial deposit) = $3000

r = the annual interest rate = 4% = 0.04

n = the number of times the interest is compounded per year = 4 (quarterly)

t = the time in years = 18

Plugging in these values, we get:

A = 3000(1 + 4%/4)^(4*18)

A = 3000(1.01)^72

A = 3000*2047

A = 6141

Rounding to the nearest whole number, we get:

A = $6141

Therefore, there will be $6141 in the account on the child's 18th birthday.

The dimensions of the ramp are approximately 1.73 feet in height, 5.19 feet in width, and 22.96 feet in length.

First we can use the formula for the volume of a rectangular prism:

volume = length × width × height

Substituting the expressions we found for the length, width, and height in terms of h, we get:

150 cubic feet = (10h + 5 feet) × (3h feet) × (h feet)

Multiplying out the terms on the right-hand side, we get:

150 cubic feet = 30h^3 + 15h^2 cubic feet

Subtracting 150 cubic feet from both sides, we get:

0 = 30h^3 + 15h^2 - 150 cubic feet

Dividing both sides by 15 cubic feet, we get:

0 = 2h^3 + h^2 - 10

This is a cubic equation that we can solve using various methods as factoring. One solution is:

h ≈ 1.73 feet

Substituting this value back into the expressions we found for the width and length, we get:

The width is 3h ≈ 5.19 feet.

The length is 10h + 5 ≈ 22.96 feet.

Therefore, the dimensions of the ramp are approximately 1.73 feet in height, 5.19 feet in width, and 22.96 feet in length.

Both the arithmetic mean and the weighted mean may be used to determine the average of a group of integers. The sum of all the numbers in the group divided by the entire amount of numbers in the set yields the arithmetic mean. Regardless of significance or relevance, it gives each integer in the set the same amount of weight. On the other hand, the weighted mean gives the integers in the set distinct weights based on their significance or relevance. This indicates that certain numbers in the set provide a greater weighted mean contribution than others.

Given that, Bobbi's goal was to save an average of $7.00 per week.

Thus the amount saved is:

Approximately 24.1% of Kelly's taxable income is her tax.

What is percent?

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.

To determine what percent of Kelly's taxable income is her tax, we need to calculate her tax liability first.

Assuming that Kelly files as a single taxpayer with no dependents and takes the standard deduction, her taxable income of $50,000 falls into the 22% tax bracket for the year 2021.

Using the IRS tax tables for 2021, Kelly's tax liability would be approximately:

$9950 + (0.22 * ($50,000 - $40,525)) = $9950 + $2095.50 = $12045.50

Therefore, Kelly's tax liability is approximately $12,045.50.

To calculate what percent of her taxable income is her tax, we can divide her tax liability by her taxable income and multiply by 100:

($12,045.50 / $50,000) * 100 = 24.09%)
