You deposit $500 in an account. The account earns $60 simple interest in 8 years. What is the annual interest rate?

Step-by-step explanation:

Sub and solve

P = p * r * t

60 = 500 * r * 2   Combine the factors.

60 = 1000 * r       Divide by 1000

r = 60 / 1000

r = 0.06

Convert this to a percent.

0.06 = x / 100 multiply both sides by 100

0.06 * 100 = x

x = 6%

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

center= (-2,0)

radius= sqrt2/2
