To calculate the interest due after missing a payment, add any late fees to the unpaid bill and apply the monthly interest rate to the outstanding balance. Interest compounds monthly, so it's crucial to pay off the debt quickly to prevent the balance from growing.
Explanation:To compute the interest due on the next bill after missing a payment for a bill, you need to consider any late fees in addition to the compounded interest. For a credit card company that charges a flat rate of $10 for a late payment and a daily rate of $5 for each day the payment remains unpaid, you would add these fees to the subtotal of the unpaid bill. Additionally, most creditors use a formula to calculate minimum payments and interest on the outstanding balance, typically on a monthly basis.
The interest on the next bill is calculated by multiplying the balance you owe by the interest rate that is applied each month. If you continue to carry a balance from month to month, this interest will be added to your outstanding balance, which will increase the amount you owe. It is important to pay off credit card debt as promptly as possible to avoid accruing additional interest.
A parking meter in downtown Seattle takes dollar coins and quarters only. When the machine was last emptied, there were 250 coins in it, with a total value of $137.50.

If the perimeter of the triangle is 52 inches, how long is the longest side? A. 10 inches B. 12 inches C. 16 inches D. 20 inches E. 24 inc
(1)
C
d + q = 250 ( total number of coins ) and
d + 0.25q = 137.50 ( total value of coins )
(2)
G
consecutive integers have a difference of 1 between them
let the integers be n and n + 1 then
2n + 3(n + 1) = 153 (distribute and simplify )
2n + 3n + 3 = 153
5n + 3 = 153 ( subtract 3 from both sides )
5n = 150 ( divide both sides by 5 )
n = 30 and n + 1 = 31
the 2 consecutive integers are 30 and 31
(3)
E
let x be the shortest side then longest side = 2x and middle side = x + 4
2x + x + 4 + x = 52
4x + 4 = 52 ( subtract 4 from both sides )
4x = 48 ( divide both sides by 4 )
x = 12
the longest side = 2x = 2 × 12 = 24

How do u Graph Y<-1/4x-1
When you replace the comparison symbol (<) with an equal sign (=), you get the equation of a line in slope-intercept form:
... y = mx + b
where m is the slope, and b is the y-intercept.
Your equation has m = -1/4 and b = -1. To graph this line, find the point (0, -1) on the y-axis. To find another point on the line, you can use the slope value (rise/run = -1/4), which tells you the line "rises" -1 for each "run" of +4. That is, another point on the line will be 4 units to the right and 1 unit down, at (4, -2). Working in the other direction (to the left, instead of to the right), the -1/4 slope tells you the point 4 units left and 1 unit up (-4, 0) will also be on the line. Draw a dashed line through these points,
The dashed line you just drew is the boundary of the solution region. It is dashed because the line itself is not part of the solution. (Those points do not meet the requirement for "less than.")
Appropriate values of y are ones that are less than those on the line, so the solution region is indicated as being the half-plane below the line. You indicate this by shading the solution region. (See the attachment for an example of the way this can be graphed.)
_____
If the comparison is ≤ instead of <, then the line is solid (not dashed), indicating it is part of the solution region. If the comparison is > or ≥, then the shaded region is above the line, where y-values are greater than those on the line.

A quadrilateral has vertices at A (-5, 5), B (1, 8), C (4, 2), and D (-2, -2). Use slope to determine if the quadrilateral is a rectangle. Show your work. (Try to use point slope form)
Answer:
not a rectangle
Step-by-step explanation:
There are several ways to determine whether the quadrilateral is a rectangle. Computing slope is one of the more time-consuming. We can already learn that the figure is not a rectangle by seeing if the midpoint of AC is the same as that of BD. (It is not.) A+C = (-5+4, 5+2) = (-1, 7). B+D = (1-2, 8-2) = (-1, 6). (A+C)/2 ≠ (B+D)/2, so the midpoints of the diagonals are different points.
___
The slope of AB is ∆y/∆x, where the ∆y is the change in y-coordinates, and ∆x is the change in x-coordinates.
... AB slope = (8-5)/(1-(-5)) = 3/6 = 1/2
The slope of AD is computed in similar fashion.
... AD slope = (-2-5)/(-2-(-5)) = -7/3
The product of these slopes is (1/2)(-7/3) = -7/6 ≠ -1. Since the product is not -1, the segments AB and AD are not perpendicular to each other. Adjacent sides of a rectangle are perpendicular, so this figure is not a rectangle.
___
Our preliminary work with the diagonals showed us the figure was not a parallelogram (hence not a rectangle). For our slope calculation, we "magically" chose two sides that were not perpendicular. In fact, this choice was by "trial and error". Side BC is perpendicular to AB, so we needed to choose a different side to find one that wasn't. A graph of the points is informative, but we didn't start with that.

... x = 20°
How do you graph these?
Answer:
See the attached.
Step-by-step explanation:
A graph of f' is a graph of the slope of the function. Your function f(x) is piecewise linear, so different sections of its graph have different constant values of slope.
In the intervals (-5, -2) and (0, 2), the slope is -1. (The graph has a "rise" of -1 for each "run" of 1.) So, in those intervals, the graph of f' looks like a graph of y=-1.
In the interval (-2, 0), the rise is 2 for a run of 2, so the slope is 2/2 = 1. The graph of f' in that interval will look like a graph of y=1.
In the interval (2, 5), the rise of f(x) is 1 for a run of 3, so the slope in that interval is 1/3. There, the graph of f' will look like a graph of y=1/3.
If you want to get technical about it, the slope is undefined at x=-2, x=0, and x=2. Therefore, the line segments that make up the graph of f' ought to have open circles at those points, indicating that f' is not defined.

Step-by-step explanation:
For what value(s) of k will the relation not be a function?
A = {(3k−4, 16), (4k, 32)}
We won't have a function if for same value of x in (x,y) we get different values y.
So first step: figure out k so that the first coordinate (x) is the same:
3k-4=4k | solve for k
k = -4
no check the values y for the elements of the relation
x = 3k-4 = -12-4=-16
so at -16 we get (-16,16) and (-16, 32), which mean for k=-4 the relation is not a function.
Let me know if you have any questions.
Answer:
K= -4
Step-by-step explanation:
Since it isn't possible that (3k-4, 16) is going to be equal to (4k, 32) in terms of positive numbers, you will have to go to the negative side of the number line.
K has to equal 4 because 3 · -4 = -12, and -12 minus 4 is equal to -16.
And since 4 · -4 = -16, K has to equal - 4.

Add 9 to both sides.
7x > 2x + 15
Subtract 2x from both sides.
5x > 15
Divide both sides by 5.
x > 3

x>3 is the answer
Step-by-step explanation:
We are given one inequality
7x-9>2x+6
To solve this we can do additions and subtraction as we do for equations.
Only for multiplication if negative number is used inequality changes
So let us add 9 to both the sides
7x>2x+6+9
Now subtract 2x from both the sides
7x-2x >15
5x>15
We divide by a positive number 5 without disturbing inequality sign.

Jack is using a ladder to hang lights up in his house.he places the ladder 5 feet from the base of his house and leans it so it reaches a window 14 feet above the ground
The angle of elevation of the ladder is approximately 70.35°
How do we find the angle of elevation?
To find the angle of elevation of the ladder, we can use trigonometric functions.
The angle of elevation can be found using the tangent function, which is the ratio of the opposite side to the adjacent side in a right triangle.
opposite side is the height from the ground to the window = 14 feet,
adjacent side is the distance from the house to the base of the ladder= 5 feet.
tan(θ) = opposite/adjacent
tan(θ) = 14/5
θ = arctan(14/5)
θ = 70.35 degrees
