Answer:
4594.76 USD will be in the account on Burt's 18th birthday.
Step-by-step explanation:
Since interest rate is constant in time, we can use the definition of composite interest to determine how much money will be on Burt's 18th birthday, that is:
(1)
Where:
- Initial amount, measured in US dollars.
- Current amount, measured in US dollars.
- Annual interest rate, measured in percentage.
- Time, measured in years.
If we know that ,
and
, then the money in the savings account on Burt's 18th birthday is:
4594.76 USD will be in the account on Burt's 18th birthday.
Answer:
a) The equation of the Parallel line to the given straight line is
6 x + y + 13 =0
b) Slope - intercept form
y = - 6 x - 13
c) The intercept - form
x - intercept =
y - intercept = - 13
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given the equation of the straight line
y = -6x +1
6 x + y - 1 = 0
The equation of the Parallel line to the given straight line is
6x + y + k=0 and it passes through the point (-3, 5 )
⇒ 6 (-3 ) + 5 + k =0
⇒ - 18 + 5 + k=0
⇒ -13 + k = 0
⇒ k = 13
The equation of the Parallel line to the given straight line is
6 x + y + 13 =0
<u><em>Step(ii):-</em></u>
Slope - intercept form
y = m x + C
y = - 6 x - 13
<u><em>Step(iii)</em></u>:-
Intercept - form
6 x + y + 13 =0
6 x + y = - 13
The intercept - form
x - intercept =
y - intercept = - 13
