To simplify this expression, you have to remember that when a number or a variable is raised to the negative exponent you have to reciprocate the number. In this expression, c^-8 will be reciprocated so it will become part of the numerator. Therefore, the final answer would be 12c^8/d^2.

There were n signers of the Declaration of Independence. The youngest was Edward Rutledge, who was x years old. The oldest was Benjamin Franklin, who was y years old. X is 25% of 104, 7 is 10% of y, and n is 80% of y. Y is what percent of (n+y-x)?
Answers
Y= 7/.10 Y=70
N= .8 x 70 N=56
n+y-x 56+70-26=100
70/100 = .7 or 70%
The answer is: Y is 70% of (n+y-x)
Answer:
70%
Step-by-step explanation:
First we calculate X using the following formula:
X = 25/100 * 104
X = 0.25 * 104
X = 26
Then we calculate Y using the following formula:
7 = 10/100 * Y
7 = 0.1 * Y
7/0.1 = Y
Y = 70
Then we calculate N as per the formula below:
N = 80/100 * Y
N = 0.8 * 70
N = 56
Finally using the formula mentioned in question we derive Y what percent of N + Y - X:
= Y/ (N + Y - X) * 100
= 70/ (56 + 70 - 26) * 100
= 70/100 * 100
= 70%

A. 13.48%.
B. 13.03%.
C. 13.02%.
D. 13.49%.
Answers
= 25,000 x 0.13 x (100/365)
= 902.78
This will be deducted from the principal amount, which is 25,000.
= 24,097
Last, we plug our values in to the effective rate formula for interest:
[tex] \frac{Interest}{Proceeds x Time of Note} [/tex]
902.78/6693.6722
= 13.487066
After rounding, we come to our final answer, which is D, 13.49%.

Kim and Leon together have $111. if kim has $17 more than Leon, how much does each person have?
Answers
The equation:
(L+17) + L = 111
The parenthesis represent how much Kim has. We can take the parenthesis out to actually solve the equation.
L + 17 + L = 111
Let's add like terms, which is L.
2L + 17 = 111
Subtract 17 on both sides.
2L= 94
Divide.
L= 47
We know Leon has 47, now we have to solve Kim by just adding 17 since she has 17 more than Leon.
47+17= 64
So Kim has 64. Let's check by adding and making sure their two values are equal up to 111.
64+47=111
Leon has $47 and Kim has $64.
Leon has $47 and Kim has $64. We solved the problem by setting up an equation with the given information and solving for each person's amount.
The question presents a typical algebraic problem. Let's denote Leon's amount of money as L and Kim's amount as K. According to the problem, Kim has $17 more than Leon, so we can write this as K = L + $17.
Since the total amount of money they have together is $111, we can formulate the following equation: L + K = $111. By substituting the first equation into the second, we get L + (L + $17) = $111.
Simplifying by combining like terms, we get 2L + $17 = $111. To find the value of L, we subtract $17 from both sides, resulting in 2L = $94. Dividing by 2 gives us L = $47.
Since K = L + $17, we substitute the value of Leon's money to find Kim's: K = $47 + $17 = $64. So Leon has $47 and Kim has $64.

Justification:
The one-point perspective is a mathematical (geometric) technique that permits to represent the real objects (which are in 3D) in a flat sheet of paper (or canvas or any flat surface use to draw), which is a 2-D figure.
With this technique, the objects appear smaller as they are further away which is what gives the illusion of 3D (perspective).
To get the effect of 3D, the lines on the drawing converge towards a point on the horizon line.

which is most likely the equation of the line shown on the graph?
Answers
The slope is up one, over one.
The equation for this line would be
y = 1/1x + 3
which is equal to
y = x + 3
Hope this helps!
Answer:
The equation of line is y=x+3.
Step-by-step explanation:
Consider the provided graph.
The slope intercept form of a line is:
y=mx+c
Where m is the slope and c is the y intercept.
y-intercept is a point where the value of x is 0.
From the provided graph we can identify the y intercept of the line is 3. Because at (0,3) the value of x is 0.
Now find the slope of line as shown
[tex]m = \frac{Rise}{Run}[/tex]
Here for 1 unit of run the graph rise 1 unit, thus the slope of the line is:
[tex]m = \frac{1}{1}=1[/tex]
Now substitute the value of m and c in the slope intercept form.
y=x+3
Hence, the equation of line is y=x+3.

hali invested money into an account that is guaranteed to grow$28 each year. she graphs a line that represents the growth of the account. with x representing the number of years since she first opened the account and y representing the number of dollars in it. what is the slope of the line?
Answers
gradient of the graph/ slope (m) = Change in y / change in x
so if we take a certain portion of the graph
x is the number of years, since we know the growth for one year,
lets take change in x as 1 year
y is amount of dollars, the change in amount of dollars for one year is 28
therefore change in y is 28
m(slope) = 28(change in y) / 1 (change in x)
= 28

Answers
We find the positive zero-crossing at x=2, and the slope of the curve at that point to be 8. Thus the line will have slope -1/8 and can be written as
.. x +8y -2 = 0
First, take the derivative of the equation given:
[tex]y = ln(2x^2-7)[/tex]
[tex]y' = \frac{4x}{2x^2-7} [/tex]
At 2, the function has a derivative of 8 (just plug in 2 to y'). So, the perpendicular to that has to have the slope -1/8 because of the negative-inverse rule. We have this until now:
[tex]y = -\frac{1}{8}x -2[/tex]
Now, we have to get a 0 on the right side, so, just get everything on the other side, and you are done.

Answers
The average rate of change on the interval is 21.
The average rate of change for any function f(x) is the ratio of change in its y-values to change in its x-values for any two particular points on the curve of the function f(x). Mathematically, we can write it as follows :-
Average rate of change = [tex] \frac{f(x_{2})-f(x_{1})}{x_{2}-x_{1}} [/tex]
It says to find the average rate of change from x = 0 to x = 10.
From the given table, x = 0 corresponds to y = f(0) = -6 and x = 10 corresponds to y = f(10) = 204.
So we have two points A(0, -6) and B(10, 204).
Using the above formula, we can find average rate of change from A to B.
Average rate of change from (0, -6) to (10, 204) = [tex] \frac{204-(-6)}{10-0} =\frac{204+6}{10} = \frac{210}{10} =21 [/tex]
Hence, the final answer is 21.

The surface area of a square pyramid is 136 square inches. The base length is 4 inches. What is the slant height?
Answers
The side length of the base is 4. Find the surface area of the base only by squaring the side length - 4² - which is 16. The surface area of the base is 16 in².
The surface area of the entire pyramid can be found using this equation:
[tex]SA = B + \frac{1}{2} nbl[/tex]
Where:
- SA is the surface area (136 square inches)
- B is the area of the base (16 square inches)
- n is the number of triangles (4, because it's a square pyramid)
- b is the base length (4 inches)
- l is the slant length
Note that we have many parts of this equation, and all we need is the slant length. So, let's format the equation with what we have:
[tex]136 = 16 + \frac{1}{2} * 4 * 4 * l[/tex]
So then we want to solve for l, the slant height. So, start by subtracting 16 from each side. This would give us:
[tex]120 = \frac{1}{2} * 4 * 4 * l[/tex]
Now, multiply both sides by 2 to get rid of the fraction:
[tex]240 = 4 * 4 * l[/tex]
Finally, divide both sides by four, twice (divide by 16):
[tex]15 = l[/tex]
So, we know that the slant height of this pyramid is 15 inches.
