What sum would yield a simple interest of 70$ in 4 years if the rate interest is 3.5% p. a

$500

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.5%/100 = 0.035 per year,

then, solving our equation

P = 70 / ( 0.035 × 4 ) = 500

P = $ 500.00

The principal required to

accumulate interest of $ 70.00

on a rate of 3.5% per year for 4 years is $ 500.00.

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
