Step-by-step explanation:
Given: Principal or P
.
Rate or R
per annum compounded annually.
Time or T
years.
To find: Percentage difference between compound interest of first year and second year.
Solution:
First year interest
.
First year amount
.
For the second year, the interest is compounded semi-annually.
So, time is doubled and the rate is halved.
Second year compounded amount
.
Second year compound interest
.
Difference in interest of first and second year
.
Percentage difference
.
Hence, the percentage difference between compound interest of first year and second year is
.
Answer:
132
Step-by-step explanation:
Divide it into 2 shapes : a triangle and a rectangle.
The triangle's base length is 20-(8+6) = 6
The height is 10-6 = 4
The triangle's area = 6*4/2 = 12
The rectangle's area is 6 * 20 = 120
Add the two together, and you get 12+120 = 132
Answer:
B.-4x^2-2x+6.
Step-by-step explanation:
=2x^2+4x-6x^2+9-6x-3.
=2x^2-6x^2+4x-6x+9-3.
=-4x^2-2x+6.
The missing side is 10.770033
Explanation: The formula for the triangle is A^2 + B^2 = C^2. So plugging that into this equation is 10^2 + 4^ = C^2, making it 116 = C^2, square root both sides and it equals 10.770033.
