Find the midpoint of A and B where A has coordinates (2,7)<br> and B has coordinates (6,3).

Veronika [31]

Given that the coordinates of the point A is (2,7) and the coordinates of the point B is (6,3)

We need to determine the midpoint of A and B

<u>Midpoint of A and B:</u>

The midpoint of A and B can be determined using the formula,

$Midpoint =(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

Substituting the points (2,7) and (6,3) in the above formula, we get;

$Midpoint =(\frac{2+6}{2}, \frac{7+3}{2})$

Adding the numerator, we have;

$Midpoint =(\frac{8}{2}, \frac{10}{2})$

Dividing the terms, we get;

$Midpoint =(4, 5)$

Thus, the midpoint of the points A and B is (4,5)

The polynomials P(x)=x^3−x−2 and Q(x)=x^2+2x+1 are multiplied and the result is completely simplified.

GarryVolchara [31]

Answer:

C. 2x^4; E. -5x

Step-by-step explanation:

P(x) = x^3 − x − 2 and Q(x) = x^2 + 2x + 1

P(x) * Q(x) = (x^3 − x − 2)(x^2 + 2x + 1) =

= x^5 + 2x^4 + x^3 - x^3 - 2x^2 - x - 2x^2 - 4x - 2

= x^5 + 2x^4 - 4x^2 - 5x - 2

Answer: C. 2x^4; E. -5x

You want to be able to withdraw $25,000 from your account each year for 25 years after you retire. You expect to retire in 15 ye

devlian [24]

Answer:

$375.49

Step-by-step explanation:

- This question tests our knowledge of annuities

-Given the desired final amount is $25,000, the term is n=25 and the interest rate is 4%, the principal amount invested can be calculated as:

$A=\frac{P(1+i)^n-1}{i}\\\\25000=\frac{P(1.04)^{25}-1}{0.04}\\\\\\=375.49$

Hence, the annual deposits are $375.49
