Find a Quadratic equation whose roots are 1.5+√2 and 1.5-√2
Answer:
x² - 3x + 0.25 = 0
Step-by-step explanation:
Given a root x = a then the corresponding factor is (x - a)
Given roots x = 1.5 + [tex]\sqrt{2}[/tex] and x = 1.5 - [tex]\sqrt{2}[/tex] then the factors are
(x - (1.5 + [tex]\sqrt{2}[/tex] ) ) and (x - (1.5 - [tex]\sqrt{2}[/tex] ) ) , that is
(x - 1.5 - [tex]\sqrt{2}[/tex] ) and (x - 1.5 + [tex]\sqrt{2}[/tex] )
The equation is then the product of the factors
(x - 1.5 - [tex]\sqrt{2}[/tex] )(x - 1.5 + [tex]\sqrt{2}[/tex] ) = 0 ← expand factors using FOIL
(x - 1.5)² - ([tex]\sqrt{2}[/tex] )² = 0
x² - 3x + 2.25 - 2 = 0
x² - 3x + 0.25 = 0

Answer:
The missing numbers are 12 and 39 respectively
Step-by-step explanation:
From the table, we can see that the ratio of the left column to the right is 3/5
So at any point in time, the values on a particular row of the table must conform
to this ratio
In other light, we have to multiply what we have on the left by 5/3 to get what’s on the right
and we have to multiply what we have on the right by 3/5 to get what’s on the left
We have this as follows;
20 * 3/5 = 12
and;
65 * 3/5 = 39
Which of the following statements are true about the graph of f(x) = 6(x + 1)2 -9?
Check all of the boxes that apply.
a. The vertex is (1, -9).
b. The graph opens upward.
c. The graph is obtained by shifting the graph of f(x) = 6(x + 1)2 up 9 units.
d. The graph is steeper than the graph of f(x) = x2.
e. The graph is the same as the graph of f(x) = 6x2 + 12x - 3.
Answer:
Step-by-step explanation:
a. The vertex is (1, -9). False. The vertex is (-1, -9).
b. The graph opens upward. True. That coefficient '6' is positive.
c. The graph is obtained by shifting the graph of f(x) = 6(x + 1)2 up 9 units. False. It's DOWN 9 units.
d. The graph is steeper than the graph of f(x) = x^2. True. The given function increases 6 times faster than does x^2.
e. The graph is the same as the graph of f(x) = 6x2 + 12x - 3.
Let's put f(x) = 6(x + 1)^2 -9 into standard form. Expanding the first term, we get f(x) = 6(x^2 + 2x + 1) - 9, or f(x) = 6x^2 + 12x + 6 - 9. YES, TRUE

Irene knows there are 2 cups in 1 pint. She writes the equation c=2p to find the number of cups, c, in any number of pints, p. Use the drop-down menus to complete the statements about Irene's equation.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as there are no options to select from.
However, a general explanation is as follows.
Given
[tex]2\ cups = 1\ pint[/tex]
Required
Is [tex]c = 2p[/tex] a correct expression?
Let
[tex]c = cups[/tex]
[tex]p = pint[/tex]
So:
[tex]2\ cups = 1\ pint[/tex]
becomes
[tex]2 * c = 1 * p[/tex]
[tex]2c = p[/tex]
Divide both sides by 2
[tex]c =\frac{1}{2}p[/tex]
Hence:
[tex]c = 2p[/tex] is incorrect

Blin and Alex raised a total of $240,000 for a charity. If Blin raised $60,000 more than Alex did, how much money did Blin raise?
Answer:
180000
Step-by-step explanation:
Solve
Given: Both Raised $240,000, Blin raised $60,000 more than Alex
To find: How much money Blin raised
Firstly, since two people raised that amount, divide the amount by 2 of them
240,000 ÷ 2 = 120,000
Nextly, subtract 60,000 from Alex's share; because Brin has more so Alex has less, less means subtract.
120,000 - 60,000 = 60,000
Now, Add that amount to Brin's share; again, Brin has more so Alex has less, less means subtract.
60000 + 120,000 = 180,000
Therefore, Brin raised $180,000
Confirm: 180,000 + 60,000 = 240,000
(For your information, Alex has $60,000)

Set of average city temperatures in April are normally distributed with a mean of 19.7°C and a standard deviation of 2°C. The average temperature of Cairo is 21.4°C. What proportion of average city temperatures are the higher than that of Cairo?
Answer:
The answer is "19.77%"
Step-by-step explanation:
Given:
[tex]\mu = 19.7\\\\ \sigma = 2\\\\\to P(x >21.4 ) = 1 - P(x< 21.4)\\\\[/tex]
[tex]= 1 - [\frac{P(x -\mu)}{ \sigma }< \frac{(21.4-19.7)}{2}]\\\\= 1 - P(z < 0.85)\\\\= 1 - 0.8023\\\\=0.1977\\\\=19.77\%[/tex]

In a sequence of numbers, a4=6, a5=10, a6=14, a7=18, and a8=22. Which recursive rule can be used to find the nth term of the sequence, an?
a1=6; an=4an−1
a1=−6; an=an−1+4
a1=6; an=an−1+4
a1=−6; an=4an−1
Common difference
a_5-a_410-64Equation
a_n=a+(n-1)4a_5=a+16a=10-16a=-6Option B
Answer:
[tex]\begin{cases} \sf a_1=-6 \\ \sf a_n=a_{n-1}+4 \end{cases}[/tex]
Step-by-step explanation:
Given:
a₄ = 6a₅ = 10a₆ = 14a₇ = 18a₈ = 22From inspection of the given terms, it is evident that there is a common difference between consecutive terms. Therefore, this is an arithmetic sequence.
A recursive formula for an arithmetic sequence allows you to find the nth term of the sequence provided you know the value of the previous term in the sequence.
From inspection of the sequence, we can see that each term is found by adding 4 to the previous term. Therefore, the recursive formula is:
[tex]\sf a_n=a_{n-1}+4[/tex]
A recursive rule comprises the recursive formula together with the 1st term a₁. To find the 1st term, keep subtracting 4 from each term:
[tex]\begin{aligned} \sf a_3 & = \sf a_4 - 4\\ & = \sf 6 - 4\\ & = \sf 2\end{aligned}[/tex]
[tex]\begin{aligned} \sf a_2 & = \sf a_3 - 4\\ & = \sf 2-4 \\ & = \sf -2\end{aligned}[/tex]
[tex]\begin{aligned} \sf a_1 & = \sf a_2 - 4\\ & = \sf -2-4 \\ & = \sf -6\end{aligned}[/tex]
Therefore, the recursive rule that can be used to find the nth term of the sequence is:
[tex]\begin{cases} \sf a_1=-6 \\ \sf a_n=a_{n-1}+4 \end{cases}[/tex]

which equation below has no solution?
In this question, we define a new operation in arithmetic, using xxas a symbol. a xxb = ab + a – b For example, 3xx7 = 21 + 3 - 7 = 17 a.Calculate 5 xx2 b. Calculate 3 xx1/2 c. Solve the equation x xx5 = 8
Answer:
a. 13 , b. = 4 , c. 2.2
Step-by-step explanation:
Given : a xx b = ab + b - a
So, no.1 xx no.2 = Product no.1 x no.2 + no.1 - no.2
As evident 3 xx 7 = (3 x 7) + 3 - 7 → 3 xx 7 = 21 + 3 - 7 = 17
Hence, 5 xx 2 = (5 x 2) + 5 - 2 → 5 xx 2 = 10 + 5 - 2 = 13
3 xx 1/2 = 3 (1/2) + 3 - 1/2 = 1.5 + 3 - 0.5 = 4
x xx 5 = 8
x xx 5 = 5x + x - 5
6x - 5 = 8
6x = 13
x = 2.16 ≈ 2.2
The Ericsson method is one of several methods claimed to increase the likelihood of a baby girl. In a clinical trial, results could be analyzed with a formal hypothesis test with the alternative hypothesis of p>0.5, which corresponds to the claim that the method increases the likelihood of having a girl, so that the proportion of girls is greater than 0.5. If you have an interest in establishing the success of the method, which of the following P-values would you prefer: 0.999, 0.5, 0.95, 0.05, 0.01, 0.001? Why? The P-value of (0.999.05.095.005-001.0001) 2 is preferred because it corresponds to the sample evidence that most strongly supports the (null/ altenative)? hypothesis that the method (is/ is not)? effective.
Answer:
0.001
Step-by-step explanation:
Ericsson is claimed to increase the likelihood of a baby girl ;
Given the alternative hypothesis to buttress this claim :
HA : p>0.5
In other to establish the success of Ericsson's claim, then there must be significant evidence to reject the Null hypothesis ; hence adopt the alternative.
To Do this, we need a very small Pvalue ; such that it will be lesser than the α - value in other to reject the Null and adopt the alternative.
Recall ;
Pvalue < α ; We reject the Null
Therefore, from the options, we choose the smallest Pvalue as we want the Pvalue to be as small as possible.

Answer:
Find the "zeros" and plug in points
Step-by-step explanation:
You can tell this graph is a parabola.
We can find the "zeros" of the graph to help us.
Find the zeros:
2x-1=0
2x=1
x=0.5
2x-5=0
2x=5
x=2.5
We can substitute values into f(x)=(2x-1)(2x-5) to graph.
You should get (1.5,-4) to be the vertex.
Hope this helps
