To see if the slopes are the same, write an equation setting the two fractions equal to each other. Is this equation true
Why or why not? What does that mean about the slope between points E and A and the slope between the points A an
C?
Answer: Slope for both is 2/3
Step-by-step explanation:
The slope for blue is 4/6, or 2/3 simplified
The slope for yellow is 2/3
Therefore, the slope is the same for both. EA and AC have the same slope.

If it takes a fan 12 minutes to walk her seat in the last section in the stadium and it takes 7 minutes to get to the
lowest-level seats, what is the average time to find a seat in these two sections at the stadium?
Answer:
9.5
Step-by-step explanation:
Probably wrong, but to find average you add up 12+7 then divide by 2, that is 19/2 which is 9.5
The average value of the time is 9.5 minutes.
What is average?"The average is defined as the mean value which is equal to the ratio of the sum of the number of a given set of values to the total number of values present in the set".
For the given situation,
Time to walk in the stadium are 12 minutes and 7 minutes.
Number of values = 2
Formula to find average,
Average = Sum of Values/ Number of values
⇒ [tex]Average = \frac{12+7}{2}[/tex]
⇒ [tex]Average = \frac{19}{2}[/tex]
⇒ [tex]Average = 9.5[/tex]
Hence we can conclude that the average value of the time is 9.5 minutes.

If the simple interest on a certain sum of money for 3 years is three-tenth of the sum,then find the rate of interest per annum
9514 1404 393
Answer:
10%
Step-by-step explanation:
We assume the "sum" being referred to in both cases is the principal amount invested. The simple interest formula tells you ...
I = Prt . . . . . . interest on P invested at annual rate r for t years
We have ...
I = 0.3Pt = 3Filling in these values, we get ...
0.3P = Pr(3)
0.1 = r . . . . . . . . divide by 3P
The interest rate is 0.1×100% = 10% per year.
39. The difference between simple and compound interest on Rs. 500 for 3 years in yearly rate of interest is Rs. 2.432. What is the rate of interest ?
9514 1404 393
Answer:
4%
Step-by-step explanation:
The multiplier for computing simple interest over a 3-year period is ...
I = Prt . . . . . interest on principal P at rate r for t years
I/P = rt = 3r
The multiplier for computing compound interest over a 3-year period is ...
A = P(1 +r)^t . . . . amount with interest
A/P -1 = (1 +r)^3 -1 . . . . multiplier for computing interest only
Then the multiplier for the difference in amounts of interest is ...
((1 +r)^3 -1) -3r = (1 +3r +3r^2 +r^3) -1 -3r = r^2(3 +r)
This means we need to solve the cubic ...
r^2(3 +r) = 2.432/500
__
This can be solved a variety of ways. Perhaps my favorite is a graphical solution. For that, we would rewrite the equation to the form ...
f(x) = x^2(3 +x) -0.004864
so the solution is found where f(x) = 0. The graph shows the solution to be ...
x = 0.04
The rate of interest is 0.04 = 4%.
_____
Additional comment
Using the above f(x) to develop a Newton's Method iterator, we find it to be ...
x' = (x²(2x +3) +0.004864)/(3x(x +2))
This needs a starting value, so we need an initial clue as to the approximate interest rate.
That can be offered by rearranging the cubic we first developed:
r = √(0.004864/(r +3))
Starting with r=0, this gives r ≈ 0.0402. At this point, we can either use this equation as an iterator, or use the Newton's method iterator above. Both will give an interest rate accurate to 4 or 5 decimal places in one iteration.
__
You may be aware from the development above that the polynomial that must be solved will have a degree equal to the number of years over which interest is computed. That is, solving the same question for a 10-year period would involve finding the root of a 10th-degree polynomial.

Answer:
opening upwardaxis of symmetry: x = 0.25vertex: (0.25, -3.25)x-intercepts: 0.25 ±√0.8125 ≈ {-0.651388, 1.151388}y-intercept: -3Step-by-step explanation:
I find it useful to graph the function using a graphing calculator. That answers most of the questions.
This function is written in standard form (terms have decreasing powers of x). It is a 2nd degree function, because the highest power of x is 2. A second-degree function is also called a quadratic. The leading coefficient is the coefficient of the term with the highest power of x. Here the leading coefficient is 4. The sign of it is positive, which tells you which way the graph opens (when the degree is even).
Opening
When the leading coefficient is positive, the function's graph opens upward. (If it were negative, the graph would open downward.)
Vertex
The vertex is the extreme point on the graph. If you want to find it algebraically, its coordinates are ...
(-b/(2a), c -b^2/(4a))
where 'a', 'b', and 'c' are the coefficients of ax² +bx +c. In this function, a=4, b=-2, c=-3, so the vertex is ...
(-(-2)/(2(4)), -3 -(-2)^2/(4(4))) = (1/4, -3 1/4)
Axis of Symmetry
The axis of symmetry is the vertical line through the vertex. It will have the equation x=constant. Of course, the constant must be the x-value of the vertex (which is why we found the vertex first).
x = 1/4
x-intercepts
The x-intercepts are where the graph crosses the x-axis. The attached graph shows an approximation of them, rounded to thousandths. You can compute the x-intercepts algebraically from the vertex and the leading coefficient.
x-intercepts = (vertex x-value) ± √(-(vertex y-value)/(leading coefficient))
x-intercepts = 1/4 ± √((3 1/4)/(4)) = 0.25 ±√0.8125 ≈ {-0.651388, 1.151388}
y-intercept
The y-intercept is the value of f(0), the point where the graph crosses the y-axis. It is always the constant in the polynomial, named 'c' above. The y-intercept is ...
y-intercept = -3
_____
Additional comment
Sometimes you want the x- and y-intercepts written as coordinates. Of course the y-coordinate of the x-intercepts is 0. Similarly, the x-coordinate of the y-intercept is 0. The coordinate ordered pairs are shown on the graph.
These are fairly standard questions that are asked about quadratic functions. It can be worthwhile to get familiar with the way they are answered. (The computation of the x-intercepts shown here is perhaps a bit unusual, but is very effective once you have the function vertex. The values it gives are correct even when the "x-intercepts" are complex numbers.)

This is the same as writing [tex]-18w^7[/tex]
=====================================================
Explanation:
The three terms we are multiplying are:
3w^(-2)2w^6-3w^3The coefficients of those terms are: 3, 2, -3
Multiplying the coefficients gets us 3*2*(-3) = -18 which is the coefficient of the final answer.
As for multiplying the w terms, we add the exponents: -2+6+3 = 7, and this is the exponent of the final answer.
Wrapping everything up, that's how we end up with -18w^7

Answer:
(16, -23)
Step-by-step explanation:
We assume your notation means the figure is dilated by a factor of 3 with the origin as the center of dilation, then it is translated 2 units left and 4 units up.
These transformations can be written as ...
(x, y) ⇒ (3x, 3y) . . . . . . . dilation by a factor of 3 about the origin
(x, y) ⇒ (x -2, y +4) . . . . translation by (-2, 4)
These two transformations together give you ...
(x, y) ⇒ (3x -2, 3y +4)
(6, -9) ⇒ (3·6 -2, 3(-9) +4) = (18 -2, -27 +4) = (16, -23)
The point is transformed to (16, -23).

Apply the next steps to solve the equation. What is the solution?
P= ?
9514 1404 393
Answer:
p = 1.2
Step-by-step explanation:
From here, it is a 2-step linear equation.
Step 1:
Identify the constant term on the side of the equation with the variable. Subtract that constant from both sides.
-10.9p = -13.08
Step 2:
Divide both sides by the coefficient of the variable.
p = -13.08/-10.9 = 1.2
The solution is p = 1.2.

determine whether the function is even odd or neither
Answer:
neither
Step-by-step explanation:
If the graph is symmetric by the y-axis the function is even OR we can say that
f(x) = f(-x) for the function to be even
for f(3) = 2 and f(-3)= 2 works yet
for f(2) = 0 and f(-2) = 1 NOT an even function
f(-x) = -f(x) will make the function odd
f(-3) = 2 and -f(3) = -2 NOT an odd function
f(-x) ≠ -f(x) will make the function neither
f(-3) = 2 ≠ -f(3) = -2 the function is neither odd or even

Answer:
Step-by-step explanation:
Pick two points and calculate the slope (Rise/Run).
I picked (-2,0) and (2,-2)
Rise = (-2 - 0) = -2
Run = (2-(-2)) = 4
Slope (Rise/Run) = -2/4 or -1/2
The line has an intercept of -1 (the "b" in y=mx + b)

PRELIMINARY
Fractions are part of a whole. For example, if an object is divided into two equal parts, the value of each part is half or one-half of the total number of objects. Fractions can be expressed in the form:
[tex] \frac{a}{b} [/tex]
a is the numeratorb is the denominatorDISCUSSION
Fractions also have fractions in different forms but have the same value which are called equivalent fractions. Fractions can also be simplified. To find a fraction equal to a fraction, we can multiply (×) or divide (÷) the numerator and denominator of the fraction by the same number. And to simplify fractions, we can divide (÷) the numerator and denominator of the fraction with the same number.
**
There are various forms of fractions, including:
Common Fractions are fractions that consist of a numerator and denominator.Mixed fractions are fractions that consist of whole numbers and fractions. If the numerator of a fraction is greater than the denominator, the fraction can be converted into a mixed number. To get the mixed number form of a common fraction, divide the numerator of the fraction by the denominator.A decimal fraction is a fraction of tenths, hundredths, thousandths, and so on written using a comma (,).Percents are another form of fraction with a denominator of one hundred. Percent is written with the symbol %.**
Now from the discussion above, it turns out that ordinary fractions still have two more types, namely =
Pure Fraction➳ A pure fraction is a fraction whose numerator is smaller than the denominator.
Impure fractions➳ An impure fraction is a fraction whose numerator is greater than its denominator.

The top is a square 3 cm by 3 cm.
The other 4 sides are rectangles. Each one is 4 cm by 3 cm.
Front: 4 cm * 3 cm = 12 cm^2
Back: 4 cm * 3 cm = 12 cm^2
Right: 4 cm * 3 cm = 12 cm^2
Left: 4 cm * 3 cm = 12 cm^2
Top: 3 cm * 3 cm = 9 cm^2
TOTAL: 12 cm^2 + 12 cm^2 + 12 cm^2 + 12 cm^2 + 9 cm^2
TOTAL: 57 cm^2
Bottom prism (blue):
Front: 5 cm * 6 cm = 30 cm^2
Back: 5 cm * 6 cm = 30 cm^2

Left: 5 cm * 6 cm = 30 cm^2
Bottom: 5 cm * 5 cm = 25 cm^2
Top: 5 cm * 5 cm - 3 cm * 3 cm = 25 cm^2 - 9 cm^2 = 16 cm^2
TOTAL: 30 cm^2 + 30 cm^2 + 30 cm^2 + 30 cm^2 + 25 cm^2 + 16 cm^2
TOTAL: 161 cm^2
Explanation for area of top of bottom (blue) prism.
Notice that the entire bottom of the top (yellow) prism is connected to the bottom prism, so there is no area of the bottom of the top prism that adds to the total surface area of the composite solid. With the bottom prism's top surface it is different. Since the top surface of the blue prism is larger than the bottom surface of the yellow prism, there is a bit of top surface of the blue prism that is seen. That area is the area of the top surface of the blue prism minus the area of the bottom surface of the top prism.
5 cm * 5 cm = 3 cm * 3 cm = 25 cm^2 - 9 cm^2 = 16 cm^2
The area of the top surface of the blue prism is 16 cm^2
