A. The axis of symmetry is x = −1.5 and the vertex is (−1.5, 8.25).
B. The axis of symmetry is x = 1.5 and the vertex is (1.5, 12.75).
C. The axis of symmetry is x = −1 and the vertex is (−1, −3).
D. The axis of symmetry is x = 0 and the vertex is (0, 6).
Answer:
B. The axis of symmetry is x = 1.5 and the vertex is (1.5, 12.75).
Step-by-step explanation:
I will solve the problem by applying the perfect square trinomial. In this way we obtain the canonical form. Another way would be to derive the function, but I don't know if you're familiar with it.
First: let us take out the common factor: , since we remember that the canonical form is characterized as follows:
Then, it remains:
Then: the coefficient of the variable We divided it between , And we square it (they will be one positive and one negative). In our case:
Let's accommodate terms to make it easier:
Can be written as :
Now, what is underlined is our perfect square trinomial, let us recall its form:
Applying the same principle we are left:
Applying distributive property we get:
Therefore it will have its vertex in:
The axis of symmetry is a straight line that makes the function to be projected being , for this you need some reference point, for the parabola you need the coordinate in of the vertex.
For which the axis of symmetry is .

8 x 2/5 in simplest form
Answer:
3 1/5
Step-by-step explanation:
8/1 = 8
8/1 * 2/5 = 16/5
16/5 = 3 1/5
Answer:
32/10, or 3 1/5
Step-by-step explanation:
One way of doing this problem is to multiply the numerators 8 and 2 together and then divide the result by 5:
8*2
-------- = 16/5
5
In turn, 16/5 can be rewritten as 32/10, or 3 1/5
The graph of the linear function f is shown in the ayplane above. The graph of the inear function g inot shown is perpendicular to the graph of fand passes through the point (1.-5) what is the value of g(-2) ?
Answer:
Step-by-step explanation:
slope of f(x) is 1/3 as y increases one unit for every three units increase in x.
Perpendicular lines have negative reciprocal slopes, so g(x) has a slope of -3
-5 = -3(1) + b
b = -2
g(x) = -3x - 2
g(-2) = -3(-2) - 2 = 4

Which of the following is the correct equation for this function?
A. v=2x² + x - 2
B. v= 2x^2 - 4x
C. 1= (x+1)(x-2)
D. V+1=2(x - 3)^2
Answer:
B. y = 2x^2 - 4x
Step-by-step explanation:
The point (0, 0) lies on the graph, so the equation has no constant term (the constant is zero). Only one answer choice has this characteristic:
y = 2x^2 -4x
Find the equation of the line with slope = 6 and passing through (-9,-58). Write your equation in the form y = mx+ b
Answer:
y=6x-4
Step-by-step explanation:
What we know
the slope is 6our point is (-9,-58)-9 is x and -58 is y so we have to find the y-intercept y=mx+b is also the formula for this
-58=6(-9)+b
-58=-54+b
-58=54+b - we changed -54 to a positive 54
54-58=-4
y=6x-4
RS = 2x + 10
ST = x - 4
RT = 21
Answer:
x = 5
Step-by-step explanation:
RS +ST = RT
2x + 10 + x - 4 = 21
2x + x + 10 - 4 = 21 {Combine like terms}
3x + 6 = 21
Subtract 6 from both sides
3x = 21 - 6
3x = 15
Divide both sides by 3
x = 15/3
x = 5

Answer:
y = 2/3x - 7
Step-by-step explanation:
(3, -5) (-3, -9)
and y = -7 when x = 0 from graph
so c = -7
m = -9 - (-5) / -3 - 3
= -4 / -6
= 2/3
line equation is y = mx + c
y = 2/3 x + (-7)
y = 2/3x - 7

for all real numbers x, sin(2x)=
For all real numbers x, the equation sin(2x) = 2sin(x)cos(x)
The trigonometric function sin(2x) represents the sine of twice the angle x.
Using a trigonometric identity, we can express sin(2x) in terms of sine and cosine of x:
sin(2x) = 2sin(x)cos(x)
This identity states that the sine of twice an angle is equal to twice the product of the sine of the angle and the cosine of the angle.
So, for any real number x, sin(2x) can be calculated by evaluating 2sin(x)cos(x).

An item on sale costs 80% of the original price. The original price was $73.
Answer:
$58.40
Step-by-step explanation:
Really simple stuff here once you know how percentages work.
10% of 73.00 is 7.30, which means that if we do:
7.30 * 2 that means we have 20%
So, 7.30 * 2 = 14.60
73.00 - 14.60 = $58.40
We can check this by doing
7.30 * 8 = $58.40

What is the probability that a random sample of 100 accounting graduates will provide an average(X¯) that is within $902 of the population mean (µ)?
Using the normal distribution and the central limit theorem, it is found that there is a 0.6328 = 63.28% probability that a random sample of 100 accounting graduates will provide an average that is within $902 of the population mean.
In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation given by [tex]s = \frac{\sigma}{\sqrt{n}}[/tex]Hence, the probability of sample having mean within M of the population mean is the p-value of [tex]Z = \frac{M}{\frac{\sigma}{\sqrt{n}}}[/tex] subtracted by the p-value of [tex]Z = -\frac{M}{\frac{\sigma}{\sqrt{n}}}[/tex].
In this problem, we suppose [tex]\sigma = 10000[/tex], and thus, with a sample of 100, we have that [tex]s = \frac{10000}{\sqrt{100}} = 1000[/tex].
Within $902, hence [tex]M = 902[/tex].[tex]Z = \frac{M}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]Z = \frac{902}{1000}[/tex]
[tex]Z = 0.902[/tex]
[tex]Z = 0.902[/tex] has a p-value of 0.8164.
[tex]Z = \frac{M}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]Z = -\frac{902}{1000}[/tex]
[tex]Z = -0.902[/tex]
[tex]Z = -0.902[/tex] has a p-value of 0.1836.
0.8164 - 0.1836 = 0.6328.
0.6328 = 63.28% probability that a random sample of 100 accounting graduates will provide an average that is within $902 of the population mean.

Correlation is the measure of the degree to which any two variables vary together.
If one variable tends to increase as the other variable decreases , the correlation is said to negative or inverse.
From the correlation we assess the strength of the relationship of two variables.
A numerical measure of strength in the linear relationship between the two variables is called co efficient of simple correlation.
The co efficient of simple correlation r is a pure number and assumes values from+1 to -1 .
r= -0.837295
The sign of r indicates the direction of the relationship or correlation.
It can be determined by finding the COV (X,Y)/ √Var (X) Var(Y)
In the given question it is calculated by using the excel sheet.
The correlation tab is found in the statistical column of the formula tab.
After entering the data in the excel the correlation tab is clicked and the rows cells are entered and the answer is obtained.
Another way is use the data analysis tab and click the correlation tab.
For both ways the following result is obtained .
