The value of x is 1.0 for the given triangle.

A triangle is classified as a right triangle when it presents one of your angles equal to 90º.  The greatest side of a right triangle is called the hypotenuse. And, the other two sides are called legs.

The math tools applied for finding angles or sides in a right triangle are the trigonometric ratios or the Pythagorean Theorem.

The Pythagorean Theorem says: (hypotenuse)²= (leg1)²+(leg2)² . And the main trigonometric ratios are:

The given triangle is a right triangle because it presents one of your angles equal to 90º. The figure shows:

Answer: 41 degrees

Step-by-step explanation: To determine the angle at which the pizza was cut, we need to use the formula for the area of a sector of a circle:

A = (θ/360)πr²

where A is the area of the sector, θ is the central angle of the sector (in degrees), π is a constant (approximately equal to 3.14), and r is the radius of the circle.

In this case, we know that the area of the sector that corresponds to the slice of pizza that was eaten is 17 square inches. We also know that the pizza has a diameter of 14 inches, which means that the radius is 7 inches.

Substituting these values into the formula, we get:

17 = (θ/360)π(7²)

17 = (θ/360)49π

θ/360 = 17/(49π)

θ = (17/49π) * 360

θ ≈ 41 degrees (rounded to the nearest whole number)

Therefore, the pizza was cut at an angle of approximately 41 degrees.

The study of random occurrences or phenomena falls under the umbrella of the mathematic discipline known as probability. It is the measure of the likelihood or chance that an event will occur, expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

To find the probabilities for a normal distribution, we need to use a standard normal distribution table or a calculator with a normal distribution function.

a. p(z > 2.10)

Using a standard normal distribution table, we can find that the area to the right of z = 2.10 is 0.0188. Therefore, p(z > 2.10) = 0.0188.

b. p(z > -1.50)

The area to the right of z = -1.50 is the same as the area to the left of z = 1.50. Using a standard normal distribution table, we can find that the area to the left of z = 1.50 is 0.9332. Therefore, p(z > -1.50) = 0.9332.

c. p(z < -0.55)

Using a standard normal distribution table, we can find that the area to the left of z = -0.55 is 0.2912. Therefore, p(z < -0.55) = 0.2912.

To calculate the compound interest on Rs 16000 at 20% per annum for 9 months, compounded quarterly, we need first to calculate the quarterly interest rate and the number of compounding periods.

Quarterly interest rate = Annual interest rate / 4

= 20% / 4

= 5%

Number of compounding periods = (Time in months) / (Number of months per compounding period)

= 9 / 3

= 3

Using the formula for compound interest:

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

where,

A = final amount

P = principal amount

r = annual interest rate

n = number of compounding periods per year

t = time in years

Plugging in the values, we get:

A = 16000(1 + 0.05/4)^(4*3/12)

A = 16000(1 + 0.0125)^1

A = 16000(1.0125)

A = 16180

Therefore, the compound interest on Rs 16000 at 20% per annum for 9 months, compounded quarterly is Rs 1800 (i.e., A - P = 16180 - 16000).

Side A and Side B are both equal to 32/3, which is 10 2/3 centimeters and the total number of hours the girls spent cleaning is 15 hours.

The perimeter of a shape can be found by adding up the lengths of all its sides.

The perimeter of a triangle is the sum of the lengths of its three sides, so in this case the equation to solve for the length of each of the two sides is:

Answer:

The answer is: m = B(3x + 1) degrees.

Step-by-step explanation:

In the given equation m/B= (3x + 1)°, we need to find the measure of m.

To find m, we need to isolate it on one side of the equation.

We can do this by multiplying both sides of the equation by B, which gives us m = B(3x + 1)°.

This means that m is equal to the product of B and (3x + 1)°.

We can simplify further by multiplying 3x + 1 by the degree symbol, which gives us m = B(3x + 1) degrees.

The formula used in this problem is m/B = angle measure, where m is the unknown side, B is the length of the known side, and the angle measure is given in degrees.

When solving problems like this, it is important to watch for units and make sure they are consistent throughout the equation.

For example, if B is measured in meters, then the units of m should also be in meters.

A real-world example of using this formula could be calculating the height of a building based on the length of its shadow and the angle of the sun's rays.

The slope of the line is 7/5 its y-intercept is (0,5) and x-intercept is (-25/7,0) when the equation of the line is 7x‐5y=‐25.

To write the equation of the line 7x-5y=-25 in slope-intercept form, we need to solve for y:

7x - 5y = -25

-5y = -7x - 25

y = (7/5)x + 5

Therefore, the equation of the line in slope-intercept form is y = (7/5)x + 5.

To find the slope, we can see that the coefficient of x is 7/5, so the slope is 7/5.

To find the y-intercept, we can see that the y-intercept is the value of y when x = 0. Plugging in x=0 into the equation, we get:

y = (7/5)(0) + 5 = 5

Therefore, the y-intercept is (0,5).

To find the x-intercept, we can set y=0 and solve for x:

0 = (7/5)x + 5

-5 = (7/5)x

x = -25/7

Therefore, the x-intercept is (-25/7,0).

To draw an accurate graph, we can plot the x- and y-intercepts and then use the slope to draw the line through those points. The slope of 7/5 means that for every 5 units to the right, the line goes up 7 units. We can use this to plot additional points and draw the line. The line should pass through the points (-25/7,0) and (0,5), and continue in both directions.

What is exponential decay?

The term "exponential decay" in mathematics refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b)x, where x is the amount of time that has passed, an is the initial amount, b is the decay factor, and y is the final amount.

To find the annual rate of change between 1992 and 2006, we can use the formula:

r = [tex](V_2/V_1)^{1/n}-1[/tex]

where V1 is the initial value, V2 is the final value, and n is the number of years between the two values.

=>r = -0.0839

Therefore, the rate of change between 1992 and 2006 is -0.0839.

To express the rate of change in percentage form, we can multiply the result from part A by 100:

=>r = -0.0839 x 100

=> r = -8.39%

Therefore, the rate of change between 1992 and 2006 is a decrease of 8.39%.

To find the value of the car in the year 2009, we can assume that the value continues to drop at the same percentage rate as calculated in part A.

From 2006 to 2009, there are 3 years. So, using the formula for exponential decay, we have:

where V0 is the value in 2006, r is the rate of decrease, and n is the number of years between 2006 and 2009.

=>V = 11792.51

Therefore, the value of the car in the year 2009 would be approximately $11,800 (rounded to the nearest $50).

Answer: Since the parabola opens down and has a focus at (0, -12), its directrix is a horizontal line located 12 units above the vertex. Let the vertex of the parabola be (h, k).

Since the focal diameter is 20, the distance between the focus and the directrix is also 20. Therefore, the directrix is the horizontal line y = k + 12, and the distance from the vertex to the focus is equal to the distance from the vertex to the directrix, which is 10.

Using the definition of a parabola, we can write:

sqrt((x - h)^2 + (y - k)^2) = 10 + (y - k - 12)

Squaring both sides, we get:

(x - h)^2 + (y - k)^2 = (10 + y - k - 12)^2

Expanding the right-hand side and simplifying, we get:

(x - h)^2 + (y - k)^2 = (y - 2)^2

Simplifying further, we get:

x^2 - 2hx + h^2 + y^2 - 2ky + k^2 = y^2 - 4y + 4

Rearranging the terms, we get:

x^2 - 2hx + h^2 + 2ky - 4y + k^2 - 4 = 0

Since the parabola opens down, the coefficient of x^2 must be negative. Therefore, we can write:

-(x^2 - 2hx + h^2 + 2ky - 4y + k^2 - 4) = 0

Multiplying out the negative sign, we get:

-h^2 + 2hx - 2ky + 4y - k^2 + 4 = 0

Therefore, the equation of the parabola that opens down, has focus (0, -12), and a focal diameter of 20 is:

-h^2 + 2hx - 2ky + 4y - k^2 + 4 = 0
