The first three terms of an arithmetic series are 6p+2, 4p²-10 and 4p+3 respectively. Find the possible values of p. Calculate the common difference for each value of p.
Answer:
First Case:
[tex]\displaystyle p=\frac{5}{2}\text{ and } d=-2[/tex]
Second Case:
[tex]\displaystyle p=-\frac{5}{4}\text{ and } d=\frac{7}{4}[/tex]
Step-by-step explanation:
We know that the first three terms of an arithmetic series are:
[tex]6p+2, 4p^2-10, \text{ and } 4p+3[/tex]
Since this is an arithmetic sequence, each subsequent term is d more than the previous term, where d is our common difference.
Therefore, we can write the second term as;
[tex]4p^2-10=(6p+2)+d[/tex]
And, likewise, for the third term:
[tex]4p+3=(6p+2)+2d[/tex]
Let's solve for d for each of the equations.
Subtracting in the first equation yields:
[tex]d=4p^2-6p-12[/tex]
And for the second equation:
[tex]2d=-2p+1[/tex]
To avoid fractions, let's multiply the first equation by 2. Hence:
[tex]2d=8p^2-12p-24[/tex]
Therefore:
[tex]8p^2-12p-24=-2p+1[/tex]
Simplifying yields:
[tex]8p^2-10p-25=0[/tex]
Solve for p. We can factor:
[tex]8p^2+10p-20p-25=0[/tex]
Factor:
[tex]2p(4p+5)-5(4p+5)=0[/tex]
Grouping:
[tex](2p-5)(4p+5)=0[/tex]
Zero Product Property:
[tex]\displaystyle p_1=\frac{5}{2} \text{ or } p_2=-\frac{5}{4}[/tex]
Then, we can use the second equation to solve for d. So:
[tex]2d_1=-2p_1+1[/tex]
Substituting:
[tex]\begin{aligned} 2d_1&=-2(\frac{5}{2})+1 \\ 2d_1&=-5+1 \\ 2d_1&=-4 \\ d_1&=-2\end{aligned}[/tex]
So, for the first case, p is 5/2 and d is -2.
Likewise, for the second case:
[tex]\begin{aligned} 2d_2&=-2(-\frac{5}{4})+1 \\ 2d_2&=\frac{5}{2}+1 \\ 2d_2&=\frac{7}{2} \\ d_2&=\frac{7}{4}\end{aligned}[/tex]
So, for the second case, p is -5/4, and d is 7/4.
By using the values, we can determine our series.
For Case 1, we will have:
17, 15, 13.
For Case 2, we will have:
-11/2, -15/4, -2.

Describe the set of nonnegative powers of 10 using the following.
(x | x = , n = 0, 1, 2, 3, …)
The set of non negative powers of 10 is given as
(x | x = 10ⁿ , n = 0,1,2,3....)
Powers of 10 is any integer powers of the number 10. In simple words 10 multiplied by itself several times.
We need to define a set of nonnegative powers of 10 using the given set builder notation .
Powers of 10 is expressed as = 10ⁿ where n = 0,1,2,....
Thus in set builder form we can write
(x | x = 10ⁿ , n = 0,1,2,3....) which states that x is such that (which is denoted as '|' ) x is equal to 10ⁿ where n is equal to 0,1,2,....
Hence the set of non negative powers of 10 is given as

Explain why a graph that fails the vertical-line test does not represent a function. Be sure to use the definition of function in your answer. Need help with this I don't know.
Answer:
The vertical line test can be used to determine whether a graph represents a function. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because a function has only one output value for each input value.

Find an equation of the line that passes through the pair of points (-5, -9) and (2,-7)
Answer:
y=0.3x - 7.6
Step-by-step explanation:
line: y=ax+b
a= Δy ÷ Δx
a= (-9 + 7) ÷ (-5 - 2)
a= -2 ÷ -7 = approximately 0.3
y=0.3x + b
Now you can fill in one of the points to find b (or both to make sure you got the answer right).
0.3 × 2 + b = -7
0.6 + b = -7
b = -7 - 0.6 = approximately -7.6
So: an equation of the line that passes through this pair of points is y=0.3x - 7.6

Ed Moura has $73000 invested in stocks paying 8%. How much additional money should he invest in certificates of
deposit paying 4% so that the average return on the two investments is 5%?
Answer:
The additional money that Ed Moura should invest in certificates of deposit paying 4% so that the average return on the two investments is 5% is 219,000.
Step-by-step explanation:
It is given that Ed Moura has $73,000 invested in stocks earning an average return of 8%, and that he should put the remaining funds in certificates of deposit paying an average return of 4%, the average return on the two investments is 5%, than;
=> 0.08 (73,000) + 0.04b = 0.05 (b + 73,000)
=> 5840 + 0.04b = 0.05b + 3650
=> 0.01b = 2190
=> b = 219,000
=> $219,000
Therefore, the additional money that Ed Moura should invest in certificates of deposit paying 4% so that the average return on the two investments is 5% is $219,000.
