Step-by-step explanation:
an = 2n^2 - 3 · Anonymous. -1, 5, 15, 29, 47, ... an = 2 n^2 - 3.
♥It says that he adds 12$ each week, and by the end of 3 weeks he had 60. Well if you do 12*3
And that =36.
But as you can see its not 60 so we have to find out how much money he had in there before.
He had 24$ in there before he started doing this.
You can find this by doing 36+x=60 and 36+24=60.
Now if you do 12*15
You get 180.
Now add the 24 dollars he already had in there.
180+24=204
He had 204$ at the end of wk.15
♥Hope this helps!♥
110% OF 70 is 77( if you meant of as in multiply)
otherwise...I'm sure its 0.77
sorry if its incorrect
hope I was able to help in some way...
Answer:
$1500
6% interest
use the formula...
P(1+(r/100))^n
where P=initial amount
r=interest rate
t=time period elapsed
so ... for 5 years we get
$1500(1+(6/100))^5 = $1500(1.06)^5 = 2007.3383664
for 10 years
1500(1.06)^10 = 2686.271544814228043264
468 months = 39 years
1500(1.06)^39=14555.261231781943250017719606544
I only know how to do a, so i hope i can help a little bit.
y=mx+b
-2=-3(7)+b
-2=-21+b
b=19
so your equation is y=-3x+19
i hope this helps!!
