Answer:
See Below
Step-by-step explanation:
The negation of a statement is almost like the opposite, but it needs to cover all cases that the statement does not.
1) x is not equal to 300.
This statement is true for all x except 300 while our original statement is true for all x except 100. These two have overlaps between what values of x could be, meaning that it is not the negation.
2) x is equal to 100.
This statement is true only for the case x equals 100 while our original statement is true for all the cases where x is not 100. These two do not overlap and cover all numbers. This means that it is the negation.
3) It is not the case that x is equal to 400.
This statement is true for all x except 400 while our original statement is true for all x except 100. These two have overlaps between what values of x could be, meaning that it is not the negation.
4) x is equal to 300.
This statement is true only for the case x equals 300 while our original statement is true for all the cases where x is not 100. This two cases have overlaps(300), meaning it is not the negation.

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.)

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.

=====================================================
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.

Step-by-step explanation:
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
Right: 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
Total surface area of the composite solid:
57 cm^2 + 161 cm^2 = 218 cm^2
Answer:
57 cm^2
Step-by-step explanation:
4 (4x3) + (3x3) = 48 + 9 = 57 cm^2

Noah started to solve the equation -4.6p - 6.3p + 3.9= 9.18 below.
1. Combine like terms: -10.9p+3.9=-9.18
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
What is the answer for this Problem?
Answer:
Increasing on the interval(s) [tex]-2\leq x\leq -4[/tex]
Decreasing on the interval(s) [tex]-1\leq y\leq 1[/tex]
Step-by-step explanation:
Anytime the graph is going upward, the function is increasing. However, anytime the graph goes down, the function is decreasing. Look at the image below for further reference. Also, when the function is increasing, the slope is positive, and when the function is decreasing the slope is negative.
The increasing interval of the graph is -3
The decreasing interval of the graph is 0.5
Since the values are in the middle of the interval, it automatically becomes the answer.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of one bottle of shampoo be = x
Let the cost of one bottle of body wash be = y
Now ,
The total cost of a bottle of shampoo and a bottle of body wash = $ 14.50
Substituting the values in the equation , we get
x + y = 14.50 be equation (1)
And ,
The cost of 3 bottles of shampoo and 5 bottles of body wash = $ 56.90
Substituting the values in the equation , we get
3x + 5y = 56.90 be equation (2)
On simplifying equation (1) and equation (2) , we get
Multiply equation (1) with 5 , we get
5x + 5y = 72.5 be equation (3)
Subtract equation (2) from equation (3) , we get
2x = 15.6
Divide by 2 on both sides of the equation , we get
x = $ 7.8
Therefore , the value of x is $ 7.8
Hence , The cost of one bottle of shampoo is $ 7.8
