The equation of the line is y=-4x+9. In order to find the equation of the line, we must first calculate the slope (m) of the line.
What is slope?Slope is a measure of the steepness of a line on a graph. It is calculated by finding the ratio of the vertical change between two points, divided by the horizontal change between the same two points.
The slope is calculated by dividing the change in y-coordinates (rise) by the change in x-coordinates (run).
In this case, the rise is -5 – (-9) = 4, and the run is 1 – 0 = 1. Therefore, the slope of the line is m = 4/1 = 4.
Next, we plug the slope and a point on the line into the point-slope form of a line equation: y - y1 = m(x - x1).
We can choose any point on the line, so let's use (0, -9).
Plugging in the values, we get:
y - (-9) = 4(x - 0)
Simplifying, we get:
y = 4x - 9
Therefore, the equation of the line is y = 4x - 9.

6. Joseph is 25 years old and has a goal to have $2 million for retirement at age 65. Assume he makes an investment that
consistently earns the current rate of inflation (7.5%). Determine how much Joseph must invest today to reach his
retirement goal.
Joseph must invest approximately $110840.16 today to reach his retirement goal of $2 million, assuming a consistent rate of inflation of 7.5%.
How to find the initial amount should be invested?To calculate the amount Joseph needs to invest today to reach his retirement goal of $2 million, we can use the future value formula for a lump sum investment:
[tex]$FV = PV x (1 + r)^n[/tex]
where FV is the future value, PV is the present value, r is the rate of return (in this case, the inflation rate of 7.5%), and n is the number of years.
In this case, we want to solve for PV, which represents the amount Joseph needs to invest today. We know that:
Joseph has 40 years until he retires (65 - 25 = 40)
His retirement goal is $2 million
The inflation rate is 7.5%
Plugging these values into the formula, we get:
[tex]$2,000,000 = PV \times (1 + 0.075)^{40}[/tex]
Simplifying, we have:
[tex]$PV = \frac{2,000,000}{(1 + 0.075)^{40}}[/tex]
PV = $2,000,000 / 18.044
Therefore, Joseph must invest approximately $110840.16 today to reach his retirement goal of $2 million, assuming a consistent rate of inflation of 7.5%.

m/B= (3x + 1)°, then find the measure of
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.

c. p(z < -0.55) = 0.2912.
Define probabilityThe 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.

Richard has a credit card that allows him to defer credit card payments for 1 year if he becomes unemployed. The interest on the card debt continues to accrue, but there are no late payment penalties. Suppose Richard has $1,597.57 in credit card debt, and the annual interest rate is 23.5% compounded monthly. How much will Richard owe (in dollars) after 1 year if he takes advantage of this option? Assume he makes no other purchases with the card. (Round your answer to the nearest cent.)
Thus, the amount of money Richard owe (in dollars) after 1 year on his credit card is $2,016.19.
Define about the term compounded monthly:Compounding interest on both the principal and the accrued interest is expressed by the term "monthly compound interest," which refers to interest that is compounded over month. The principal amount times one plus the interest rate divided by a number of periods, raised to the power of such number of periods, is how monthly compounding is computed.
Formula for amount after compounding:
A = P[tex](1 + r/n)^{nt}[/tex]
A = amount after compounding
P is principal (=$1,597.57)
r is rate of interest (23.5%)
n is the number of times compounded (= 12)
t is time in years (1 year)
A = 1597.57* [tex](1 + 0.235/12)^{12*1}[/tex]

Find the compound interest on Rs 16000 at 20% per annum for 9 months compound quarterly
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).
Determine the equation of the parabola that opens down, has focus (0, -12), and a
focal diameter of 20.
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

r=---------------%
C) Assume that the car value continues to drop by the same percentage. What will the value be in the year 2009 ?
value = $ -----------------Round to the nearest 50 dollars.
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).

A friend is curious what the probability of it snowing today is. What would the complement of this event be? explain how you would calculate the complement of an event. 
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
So the probability of it not snowing today is 0.7 or 70%.

Brian invests £8500 into his bank account.
He receives 5.7% per year compound interest.
How much will Brian have after 6 years?
Give your answer to the nearest penny where appropriate.
CH please help me and give explanation and step by step and answer.
Answer:o calculate the compound interest, we can use the formula:
A = P(1 + r/n)^(nt)
where:
A = the final amount
P = the principal amount (initial investment)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the time period (in years)
In this case, P = £8500, r = 5.7% = 0.057, n = 1 (since the interest is compounded annually), and t = 6.
So, plugging in the values:
A = £8500(1 + 0.057/1)^(1*6)
A = £8500(1.057)^6
A = £11260.23
Therefore, Brian will have £11260.23 in his bank account after 6 years with compound interest. Rounded to the nearest penny, the answer is £11,260.23.
Step-by-step explanation:
The answer is 625cm. but I can't do the steps
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
2.) You eat 1 slice of a 14 inch pizza, which represents 17 in² of the pizza. At what angle was the pizza cut? Round to the nearest whole number
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.
) Determine the equation of the line 7x‐5y=‐25 in slope‐intercept form, then determine the slope, the y‐intercept, the x‐intercept, and draw an accurate graph
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.
