Formula for compounding continuously is:
A = Pe^(RT)
A = Amount, P = Principal, e = constant ≈ 2.71828..., R = Rate per year,
T = Time.
A = ?, P = $1400, R = 5.5% = 5.5/100 = 0.055, T = 6 years.
A = Pe^(RT)
A = 1400*(2.71828)^(0.055*6) use a calculator.
A ≈ 1947.35
Amount or balance is ≈ $1947.35
I hope this helps.
19.5inches
This is because
4 13
— = —
6 x
Cross multiply and you get 4x = 78
Since you want x, you isolate it and to do that, you have to divide both sides by 4
4x = 78
— —
4 4
So x = 78/4
The length is 19.5
(6x + 30)+(2x+6)= 180
8x +36= 180
8x= 144
X= 18
So 2x+6 = 42
And 6x+30 = 138
Answer:
and
Step-by-step explanation:
First move everything to the same side:
--->
Then use the quadratic formula:
x= (-b ± )/2a
x= (-(-10) ± )/2*1
x= (10 ± )/2
Solution 1:
(10 + )/2
=
Solution 1:
(10 - )/2
=
