the value of P(7), given P(x) = negative4(x minus 15)2 + 2 is 1721.
The problem above can be solved using the ideal of polynomial.
What is a Polynomial?Polynomials are mathematical expressions whereby the highest degree of their unknown is 2 and above.
Given:
P(x) = negative4(x minus 15)2 + 2P(x) = -4(x-15)²+2Expand the expression
P(x) = -4(x²-30x+225)+2P(x) = -4x²+120x+900+2P(x) = -4x²+120x+902To find P(7), we subtitute 7 as the value of x in the expression above
P(7) = -4(7²)+120(7)+909P(7) = -28+840+909P(7) = 1721Hence, the value of P(7), given P(x) = negative4(x minus 15)2 + 2 is 1721.

When the government decides to decrease government purchases by $250 billion, this will lead to a $175 billion decrease in income.
How to calculate the decrease in income?From the information, the government decides to decrease government purchases by $250 billion. The decrease in income will be:
= $250 × 0.7
= $175 billion
This decrease in income yet again will cause a second change in consumption equal to:
= $175 × 0.7
= $122.5 billion
The total change in demand resulting from the initial change in government spending will be:

The total amount accrued, principal plus interest, with compound interest on a principal of $13,500.00 is $19,377.24.
Compound InterestGiven Data
Principal P = $13500Rate r = 7.25%Time = 5 yearsA = P + I where
P (principal) = $13,500.00

First, convert R as a percent to r as a decimal
r = R/100
r = 7.25/100
r = 0.0725 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt

The statement about the design that is correct is that; This a block design with fields as blocks and seed types as treatments.
What is random block design?
From the complete question seen online, we see that the researchers in this agricultural testing divide each field into six sections and then randomly assign one variety of corn seed to each section in that field.
Now, we are further told that this procedure above is repeated for each field and at the end of the growing season, the corn will be harvested, and the yield measured in tons per acre will be compared.
Finally, we can say that this is a block design because it is an experiment where the fields that have certain characteristics are grouped together to form blocks, while the treatments are the variety of corn seeds that are randomly assigned within each block.

Evaluate the indefinite integral as an infinite series. arctan(x2) dx
The indefinite integral expressed as an infinite series is;
[tex]= (\Sigma^{\infty} _{n = 0} (-1)^{n} \frac{1 }{2n + 1} * \frac{(x)^{4n + 3}}{4n + 3}) + C[/tex]
How to find indefinite integral?We will first have to look for the Maclaurin series of arctan(x).
We'll recall that from online tables of integral, this Maclaurin series of arctan(x) will have the general formula;
[tex]arctan(x) = \Sigma^{\infty} _{n = 0} (-1)^{n} \frac{x^{2n + 1} }{2n + 1}[/tex]
When we apply that general Maclaurin series of arctan(x) to our question of arctan(x²), we have the expression as;
[tex]arctan(x^{2} ) = \Sigma^{\infty} _{n = 0} (-1)^{n} \frac{(x^2)^{2n + 1} }{2n + 1}[/tex]
⇒ [tex]= \Sigma^{\infty} _{n = 0} (-1)^{n} \frac{(x)^{4n + 2} }{2n + 1}[/tex]
We now integrate the expression that we got above in the following manner to get;
[tex]\int\limitsarctan(x^{2} ) = \int\Sigma^{\infty} _{n = 0} (-1)^{n} \frac{(x)^{4n + 2} }{2n + 1} dx[/tex]
⇒ [tex]= (\Sigma^{\infty} _{n = 0} (-1)^{n} \frac{1 }{2n + 1} * \frac{(x)^{4n + 3}}{4n + 3}) + C[/tex]
Thus, that expression gives us the indefinite integral of arctan(x²) as an infinite series.
