Answer:

As the height of the rider increases by 1 inch, the bike frame increases by 0.29 inches

Step-by-step explanation:

Lets label what we know here:

b = size of the bike frame in inches

h = height of the rider in inches

We are also given the equation [tex]b=0.29h+1.35[/tex], which is in slope intercept form. This means that the y intercept is 1.35 and the slope is 0.29.

This means that, as the height of the rider increases by 1 inch, the bike frame will also increase. Lets put this to the test:

[tex]b=0.29(1) + 1.35[/tex]

[tex]b=1.64[/tex]

We will get a different size of the bike frame depending on what we set h equal too.

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.

So the probability of it not snowing today is 0.7 or 70%.

what is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a numerical value between 0 and 1, where 0 indicates an impossible event and 1 indicates a certain event. Probability theory is a branch of mathematics that deals with the study of random events and their properties.

In the given question,

The complement of an event is the probability that the event does not occur. In this case, the complement of "it snows today" would be "it does not snow today".

To calculate the complement of an event, you can subtract the probability of the event from 1. So if the probability of it snowing today is 0.3 (or 30%), then the probability of it not snowing today would be:

1 - 0.3 = 0.7

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).

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

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.

Step-by-step explanation:

Area of ENTIRE circle = pi r^2 = pi (18)^2 = 1017.876 cm^2

the shaded area is   221 out of 360    ( 360 is the ENTIRE circle area)

221 / 360   * area =   221/ 360 * 1017.876  = 624.8 = ~ 625 cm^2

The intercepts of h(x) are (-1, 0), (4, 0), and (0, 4), and the asymptotes are x = 2 and y = 3. To find these intercepts and asymptotes using the graph, we need to look for the points where the graph intersects the x-axis and the y-axis, and where the function approaches infinity or a constant value as x approaches certain values.

From the graph, we can see that the function h(x) has a vertical asymptotes at x = 2, which means that as x approaches 2 from either side, the function approaches positive or negative infinity. We can also see that the function has a horizontal asymptote at y = 3, which means that as x approaches positive or negative infinity, the function approaches 3. To find the intercepts of h(x), we need to look for the points where the graph intersects the x-axis and the y-axis. From the graph, we can see that the function intersects the x-axis at x = -1 and x = 4, which means that these are the x-intercepts.

In the exponential decay, A) r = -0.0839 , B) r = -8.39% , C) Value=$11,800.

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).

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)
