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.

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

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

Answer:

c. 31 million square inches

Step-by-step explanation:

Hope this helped have an amazing day!

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.
