You can use the formula A=P(1+r/n)^nt
A=the future value of the starting amount
P=the starting amount
r= the interest rate number of times the interest is compounded per year
t=the number of years the amount is loaned for
A=900(1+0.03/1)^1x4
A=1012.95
I hope this helps. Also if I am wrong our did not fallow the question completely please let me know in the comments so that I can try to fix it .
C=24
b=8
a=?
a2=c2-b2
a2=(24)2-(8)2
a2=576-64
a2=512
take LCM
a=22.627.....
X^2 + 9x^2
----------- = 16
(x + 3)^2
multiply each term by (x + 3)^2:-
x^2(x + 3)^2 + 9x^2 = 16(x + 3)^2
x^2( x^2 + 6x + 9) + 9x^2 = 16x^2 + 96x + 144
x^4 + 6x^3 + 18x^2 = 16x^2 + 96x + 144
x^4 + 6x^3 + 2x^2 - 96x - 144 = 0
This is difficult to solve algebraically so I drew a graph There are 2 real roots
x = -1.65 and x = 3.65 to nearest hundredth
You need 5 more gallons for a full tank.
Since it takes 10 gallons to increase the gauge from 1/4 to 3/4 (change of 2/4 which is the same as 1/2), it must have taken 10 gallons to fill up to halfway for the tank.
Thus the full amount would be 10*2 = 20 gallons
However, since there is already 3/4 gasoline in the tank, we only need an extra 1/4 of 20 for it to be full.
So, 20*1/4 = 5
We need to add 5 gallons for a full tank.
