Find the sum and enter it in the box below. Enter your answer as a polynomial in descending order, and use the caret() for exponents. For example, you would write 4x2 as 4x^2. (x9 - X + 8) + (10x9 + 7)​

Find and simplify an expression for the area of five rows of x squares with side lengths of x centimeters .

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

A. use the formula for continuous compounding with the original example: $1000 invested at 2% for 1 year. record the amount to 5 decimal places. use a calculator. b. compare it to the result using the original compound interest formula with n = 365 calculated to 5 decimal places. which has a larger value? explain.
