Answer:
Where are the graphs?
Step-by-step explanation:
tell me a some basic terms related bijective.
1:A function of F:R --->is defined by f(x)=x²-1,is f one to one an onto.
2:
A function F:[-2,2]-->R is defined by f(x)=x² is
F one to one and onto.
3:
A function F:[1,4]-->R is defined by f(x)=x³ is
F one to one and onto
Answer:
1. f(x) = x² - 1 is an even function.
It has two-to-one relationship since f(-x) = f(x)
The answer is no
2. f(x) = x², same as above, the answer is no
3. The function f(x) = x³ is an odd function and its inverse is:
f(x) = ∛x, which is also an odd functionBoth have one-to-one and onto relationship
The answer is yes
Which of these expressions is equal to 2(43 - p)?
A.
(2 - 43) × (2 - p)
B.
(2 - 43) - (2 - p)
C.
(2 × 43) - (2 × p)
D.
(2 × 43) × (2 × p)
Answer:
C. (2×43) - (2×p)
Step-by-step explanation:
The question is 2(43-p)
Which means 2 is multiplying the bracket.
So the answer to the question is 2×43 - 2×p
Which will give us 86 - 2p
So you then solve all the possible answers to see if it the same answer as the one we got

is equivalent to 16 Superscript three-fourths?
I can help you in the comments section. Can you rephrase this question?
Answer:B
Step-by-step explanation:
In 2011, there were 150 participants in a quiz competition. In 2012, there were 185 participants in this quiz competition.
Select the true statement about participants in the quiz competition from 2011 to 2012. Percentages are rounded to the nearest tenths place.
a.) The absolute change is 35 students and the relative change indicates an increase of 18.92%.
b.) The absolute change is -35 students and the relative change indicates a decrease of 23.3%.
c.) The absolute change is 35 students and the relative change indicates an increase of 23.3%.
d.) The absolute change is -35 students and the relative change indicates a decrease of 35%.
Answer:
c.) The absolute change is 35 students and the relative change indicates an increase of 23.3%
Step-by-step explanation:
the participants increasing = 185-150=35
the percentage = 35/150 × 100% = 23.3%
Option (C) The absolute change is 35 students and the relative change indicates an increase of 23.3% is correct.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
In 2011, there were 150 participants in a quiz competition. In 2012, there were 185 participants in this quiz competition.
c) The absolute change is 35 students and the relative change indicates an increase of 23.3%
The change in participent = 185 - 150 = 35
Percentage change = (35/150)×100 = 23.3%
Thus, option (C) The absolute change is 35 students and the relative change indicates an increase of 23.3% is correct.

Find the height in centimeters of a square pyramid with a volume of 455cm3 and a base edge length equal to the height. Give the approximate answer rounded to 2 decimal places.
Answer:
[tex]h = 7.69cm[/tex]
Step-by-step explanation:
Given
[tex]Volume = 455cm^3[/tex]
[tex]l = h[/tex]
Where:
[tex]h \to height[/tex]
[tex]l \to base\ length[/tex]
Required
The height
The volume is calculated as:
[tex]Volume = l^2 * h[/tex]
This gives:
[tex]Volume = h^2 * h[/tex]
[tex]Volume = h^3[/tex]
Rewrite as:
[tex]h^3 =Volume[/tex]
So, we have:
[tex]h^3 = 455cm^3[/tex]
Take cube roots
[tex]h = \sqrt[3]{455cm^3}[/tex]
[tex]h = 7.69cm[/tex] --- approximated
Write an equation for the lowest-degree polynomial function, with the graph and intercepts shown in the figure. For this exercise, make the leading coefficient be 1 or -1
Answer:
f(x) = (x+1)² - 9
Step-by-step explanation:
We can start by seeing if this is a quadratic function, as that is the lowest degree polynomial possible.
The vertex form for a quadratic function is a(x-h)² + k, with the vertex being (h, k).
In this example, the leading coefficient (a) must be 1 or -1. If a is positive, the graph opens upward, and vice versa. Since the graph opens upward, a must be 1.
Our vertex in this picture is (-1, -9). We can plug those values in, along with a=1, to get
1(x-(-1))² - 9 = (x+1)² - 9
Therefore, our equation is f(x) = (x+1)² - 9
The polynomial is given by:
[tex]p(x) = x^2 + 2x - 8[/tex]
------------------------
Zeros of a function:
Given a polynomial f(x), this polynomial has roots [tex]x_{1}, x_{2}, x_{n}[/tex] such that it can be written as: [tex]a(x - x_{1})*(x - x_{2})*...*(x-x_n)[/tex], in which a is the leading coefficient.
------------------------
The polynomial has two x-intercepts, thus, the lowest-degree is 2.Concave up, thus, the leading coefficient is [tex]a = 1[/tex].The x-intercepts are [tex]x_1 = -4, x_2 = 2[/tex], and thus:[tex]p(x) = (x - (-4))(x - 2) = (x + 4)(x - 2) = x^2 + 4x - 2x - 8 = x^2 + 2x - 8[/tex]

Why do you think using computer software to do forecasting calculations is almost necessary if you are changing the number of time periods for a moving average or the alpha value for an exponential smoothing calculation
Answer:
There are two major methods of forecasting
One is the Causal method and the 2nd one is the times series method
Causal method mainly tries to find out cause and effect relation between variable and various factors impacting that variable while the time series method infuences the utilization of the historical data and mainly focus to forecast based on the trend present. It simply ignores the other variables. It just tries to give an idea of a trend, it can't predict the impact of other variables as in causal method.
Linear regression analysis can be utilized in both sort of estimating technique. By linear regression analysis we can anticipate effect of different factor on factor variable. It anticipate the pattern, yet additionally gives an idea about connection among variable and different elements affecting it. That is the reason Linear regression is considered as best technique for forecasting.
Presently, going to the next part of this inquiry, Time period utilized in moving normal is settled based on fluctuation showing up in how much period, to smoothen out the variation. Also, Alpha value is chosen dependent on the time span to smoothen out the variation in the information. Changing of time-frame or distinctive alpha will make estimation complex. And furthermore, it will make computation more probabilistic as opposed to deterministic which may create mistake whenever done by manual calculation. That is the reason program are important in such sort of computation
