Answer: The three integers are x = -7, x+1 = -6 and x+2 = -5.
Step-by-step explanation:
We can set up the equation: x(x+1)(x+2) = -210, where x, x+1, and x+2 are the consecutive integers.
To solve for x, we can start factoring -210.
-210 = -1210 = -12105 = -1370 = -12514 = -12572
Since we are looking for three consecutive integers, we know that one of the factors must be -1 and the other two factors must be a pair of integers.
-1 * 2 * 5 * 7 = -70
-1 * 2 * 5 * 14 = -140
-1 * 3 * 7 = -21
So, the three integers are x = -7, x+1 = -6 and x+2 = -5.

Step-by-step explanation:
Henry has worked for a factor for 31 years and will be retiring. He earned salaries over the past 4 years of $38433, $37776, $39125, and $38782. His employer calculates pension by finding the average of his last 4 years’ salaries and will give him 1. 9% of that average for each year he worked. Calculate his pension
After calculating the average of his last 4 years’ salaries and will give him 1. 9% of that average for each year he worked, the total pension is $2928.204.
In the given question, we have to calculate Henry pension.
Henry has worked for a factor for 31 years and will be retiring.
He earned salaries over the past 4 years of $38433, $37776, $39125, and $38782.
His employer calculates pension by finding the average of his last 4 years’ salaries and will give him 1.9% of that average for each year he worked.
His earning over the past 4 years = $38433, $37776, $39125, $38782
The average of Henry earning = Sum of his earning over 4 years / number of years
The average of Henry earning = ($38433 + $37776 + $39125 + $38782)/4
The average of Henry earning = $154,116/4
The average of Henry earning = $38,529
Hence, the average of Henry last 4 years’ salaries is $38,529.
The pension is 1.9% of the average salary. So,
Pension = $38,529×1.9%
Pension = $38,529×0.019
Pension = $732.051
He worked for total 4 years. So,
Total pension = $732.051×4
Total pension = $2928.204

rank the magnitude of each object’s acceleration from greatest to least. disregard the direction of the accelerations.
The rank of object according to acceleration from greatest to least is:
C = B > A
In the given question, we have to rank the magnitude of each object's acceleration from greatest to least: Disregard the direction of the accelerations.
The acceleration is given by:
a = [tex]\frac{dv}{dt}[/tex]
where, dv represents change in velocity and dt represents change in time.
Also, Acceleration = slope of velocity - time graph
For object A acceleration is 0 because velocity is constant.
Now for object B:
[tex]a_{B}=\frac{5-0}{10-0}[/tex]
[tex]a_{B}=\frac{5}{10}[/tex]
[tex]a_{B}=\frac{1}{2}[/tex]
[tex]a_{B}[/tex] = 0.5 m/s square
Now for the object C:
[tex]a_{C}=\frac{-5-0}{10-0}[/tex]
[tex]a_{C}=-\frac{5}{10}[/tex]
[tex]a_{C}=-\frac{1}{2}[/tex]
[tex]a_{C}[/tex] = -0.5 m/s square
As we know that magnitude cannot be negative, so
[tex]a_{C}[/tex] = 0.5 m/s square
As we can see that acceleration of object B and C is same although the acceleration of object A is 0 which is smaller than the acceleration of B and C.
So the rank of object according to acceleration from greatest to least is:

An iceberg weighs 450,000 pounds. If it loses 0. 2% of its weight in a day, what is its new weight at the end of the day?
The new weight at the end of the day will be = 450000-9000 = 441000 Pounds.
The current weight of the Iceberg = 450,000 pounds
Percentage decrease in weight every day = 0.2%
So, for determining the value of the percentage decrease in the weight, we need to first find the value of 2% of 450000
For converting the value given in percentage to the fraction value we will divide the given number by 100.
So, the value 2% can be written as (2/100)
Now calculate the value of 2% of 450000
We will get it as:
(2/100)*450000 = (2*4500) = 9000 Pounds.
After a day, the weight of the iceberg decreases by 9000 Pounds
So, for determining the value of weight at the end of the day, we will subtract the value decreased during the day from the value of weight at the start of the day.

To translate a function left or right, you need to shift the graph of the function horizontally. If you want to move the graph to the left, you need to subtract the same amount from each x-coordinate. This means that all the points on the graph will be shifted to the left by the same amount. For example, if the graph of the function is f(x) = x² and you want to move it left by two units, you need to subtract two from each x-coordinate so the new graph would be f(x) = (x-2)². Similarly, if you want to move the graph right, you need to add the same amount to each x-coordinate. For example, if the graph of the function is f(x) = x² and you want to move it right by three units, you need to add three to each x-coordinate so the new graph would be f(x) = (x+3)².

6.6 oz for $2.50 or 30 oz for $11.29. Which one is better?
Answer:
30 oz for $11.29
Step-by-step explanation:
We can find the unit cost for each and compare.
We need both in dollars per ounce, so we divide the number of dollars by the number of ounces for each case.
6.6 oz for $2.50
Unit cost = $2.50 / 6 oz = 0.41666... $/oz
30 oz for $11.29
Unit cost = $11.29 / 30 oz = 0.376333... $/oz
At $0.38/oz, 30 oz for $11.29 is a better buy than 6.6 oz for $2.50 which is $0.42/oz.
Answer: 30 oz for $11.29
molly wants to buy a skirt. the original price is $29. the skirt is on sale for 30% off. when she goes to pay for it the cashier tells her she can have an additional 20% discount off the sale price. not counting the sales tax, how much will molly pay for the skirt?
The total amount of money molly will pay for the skirt after the total discount is $14.5
How to determine discount?Original price of the skirt = $29
Percentage discount = 30%
Additional percentage discount = 20%
Total percentage discount = 30% + 20%
= 50%
Total amount molly paid for the skirt not counting the sales tax = $29 - (50% of $29)
= 29 - (0.50 × 29)
= 29 - 14.5
= $14.5

The inverse of a one-to-one function f: A → B, is the function g: B → A, having the following property
f(x) = y ⇔ g(y) = x
The function f is named invertible if its inverse function g exists.
When is a function from set S to set T then the inverse of f will be a function g from T to S such that each of f and g unties the other: for every s ∈ S we have g(f(s)) = s and for every t ∈ T we have f(g(t)) = t.

how do you graph a linear equation with a fraction in it?
The linear equation with a fraction in it can be solved by using y-intercept form method.
What are linear equations?
A linear equation is one in which the variable's maximum power is always 1. A one-degree equation is another name for it. A linear equation in one variable has the conventional form Ax + B = 0. In this equation, x is a variable, A is a coefficient, and B is constant. A linear equation in two variables has the conventional form Ax + By = C. The variables x and y are variables, the coefficients A and B are coefficients, and the constant C is a constant.
Now,
y-intercept form-
Make sure the linear equation is in the form y = mx + b. This is called the y-intercept form, and it's probably the easiest form to use to graph linear equations. The values in the equation do not need to be whole numbers. Often you'll see an equation that looks like this: y = 1/4x + 5, where 1/4 is m and 5 is b.[1]
m is called the "slope," or sometimes "gradient."[2] Slope is defined as rise over run, or the change in y over the change in x.
b is defined as the "y-intercept." The y-intercept is the point at which the line crosses the Y-axis.[3]
x and y are both variables. You can solve for a specific value of x, for example, if you have a y point and know the m and b values. x, however, is never merely one value: its value changes as you go up or down the line.
