Answer:
y = - 2x + 8
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x - 9 ← is in slope- intercept form
with m =
given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= - 2
y = - 2x + c ← is the partial equation
to find c substitute (3, 2 ) into the partial equation
2 = - 6 + c ⇒ c = 2 + 6 = 8
y = - 2x + 8 ← equation of perpendicular line
Answer:
The amount at the end of second quarter is $1842.704
Step-by-step explanation:
Given as :
The principal in saving account = $1640
The rate of interest = 6 % compounded quarterly
The time period = 6 months
Now,<u> from compounded method</u>
The amount at the end of first quarter = = principal + 6 % of principal
I.e = $1640 + 6 % × $1640
Or, = $1640 + $ 98.4
∴ = $1738.4
Again ,
The amount at the end of second quarter = =
+ 6 % of
I.e = $1738.4 + 6 % × $1738.4
Or, = $1738.4 + $104.304
∴ = $1842.704
So, The amount at the end of second quarter = = $1842.704
Hence , The amount at the end of second quarter is $1842.704 Answer
