Ian invested $1,315 in a savings account which earns 2.86% interest compounded quarterly. what will the account be worth in nine years

In 9 years, the account will be worth $1699.48

Step-by-step explanation:

Compound interest is interest calculated on the initial principal and also on the accumulated interest of previous periods of a deposit or loan. Ian invested $1.315 in savings account which earns 2.86% interest compunded quaterly.

The ammount of money the account will be worth is given by the formula:

where r: Rate of annual interest = 2.86%

n: the number of years = 9

P= Principal ammount = $1315

Then A= $1699.48

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
