7900 dollars is placed in an account with an annual interest rate of 5.5%. How much will be in the account after 11 years?

My name is Ann [436]

Answer:

$\$12,679.50$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=11\ years\\ P=\$7,900\\ A=?\\r=5.5\%=5.5/100=0.055$

substitute in the formula above

$A=7,900(1+0.055*11)$

$A=7,900(1.605)$

$A=\$12,679.50$

Miss Sandy is fencing in her rectangular backyard which is 3x^2 feet wide and 4xy + 5x^3 y^2 feet long. Find perimeter of yard H

hjlf

Given:

Width of rectangular backyard = $3x^2$ feet

Length of rectangular backyard = $4xy+5x^3y^2$ feet

To find:

The perimeter of yard.

Solution:

Formula or perimeter of a rectangle is

$Perimeter=2(length +width)$

Using this formula, the perimeter of the rectangular backyard is

$Perimeter=2(4xy+5x^3y^2+3x^2)$

$Perimeter=8xy+10x^3y^2+6x^2$

Therefore, the perimeter of the rectangular backyard is $8xy+10x^3y^2+6x^2$ feet. So, $8xy+10x^3y^2+6x^2$ feet fencing is needed.
