Answer:
4444.63
Step-by-step explanation:
after 1st year money will be 3000 + 0.14 *3000 =3420
after 2nd year 3420 + 0.14*3420 =3898.80
after 3rd yeaar 3898.80 + 0.14*3898.80 = 4444.632
Answer:
$50.23
Step-by-step explanation:
f(t)=1.35(t)+9.73
First I found out how many years are after 1985 so you would do 2020-1985 which equals 30.
I plug it in for t.
f(t)=1.35(30)+9.73
Then you multiply 1.35 and 30 which would leave us with.
f(t)=40.5+9.73
Add them and you get $50.23
Regroup:
(x^4+2x^2-8)-(x^3+4x)=0
Factor: (x^2-2)(x^2+4)-x(x^2+4)=0
both terms have (x^2+4), so (x^2+4)(X^2-x-2)=0
factor again: (x^2+4)(x+1)(x-2)=0
x=1, x=2, x=2i, or x=-2i
4+1=5
-3-4=-7
-5/7 is slope
y+1=-5/7(x-4) < this is point slope form
hope this helps
