Answer:

Since r is the distance from the origin to (x,y), it is the magnitude r=√x2+y2. Alternatively, from the equation (1), one can calculate directly that x2+y2=r2cos2θ+r2sin2θ=r2(cos2θ+sin2θ)=r2.

Write the expression. Then, check all that apply. twice the difference of a number and six A 2-column table with 4 rows. Column
Pie

The statements that apply to the algebraic expression are

  • Replace “a number” with the variable, n.
  • The two operations are multiplication and subtraction.
  • The constants are 2 and 6.
  • The expression is written as 2(n – 6)
<h3 /><h3>How to determine the algebraic expression?</h3>

The complete question is added as an attachment

The statement is given as:

Twice the difference of a number and six

Represent the number with n.

So, the statement becomes

Twice the difference of a n and six

Twice means 2 *

So, we have

2 * difference of a n and six

Express difference as minus i.e. -

So, we have

2 * (n - 6)

Hence, the expression is written as 2(n - 6)

BUILD PERSEVERANCE The formula A = P(1 + r) represents the amount of money A in an account after t years, where P is the amount
Veseljchak [2.6K]

The solution for P is P = A / (1 + r)^t, the initial deposit is $1,510, and I agree that A is always greater than P when given the conditions stated.

<h3>How do we calculate the initial deposit?</h3>

The correct formula in the question is provided as follows:

A = P(1 + r)^t ........................ (1)

a. P can be solved for and the amount of Patricia's initial deposit can be found from equation (1) as follows:

P = A / (1 + r)^t ................................. (2)

Where:

A = $1839.79

r = 2.5% = 0.025

t = 8

Substituting all the relevant values into equation (2), we have:

P = $1839.79 / (1 + 0.025)^8

P = $1,510

b. Yes, I agree.

The reason is that interest at the rate of 2.5% will be earned yearly on P and added to A making A always greater than P.
