Answer:
$3391.54
Step-by-step explanation:
compound interest formula is
× 
Fv= future value
Pv= present value
i= annual interest rate
n= number of days/months/weeks etc
t= time in years
in this case I used "i" as weekly interest rate
ANSWER
The points (1,2) and (7,2) lie on the given curve.
EXPLANATION
The given parametric equations are:

and

We make t the subject in the first equation to obtain:

We substitute this into the second equation to get:

When x=1,

When x=2

When x=7,

Therefore the points (1,2) and (7,2) lie on the given curve.
The third one is linear because it goes down by -8 each time,
Hope this helps! :)
I divided 2.25 by 2/3 and got 1.50. That may be the answer if it's a choice.
Here is your solution,
(-5)^2 - √25 - 4 x (-14)/2
25 - √ 25 + 56/2
25 - √81/2
(25 - 9)/2 = 16/2 = 8
or
25 + √25 +56/2
25 + √81/2
(25 + 9)/2 = 34/2 = 17
So m = 8,17
