Answer:
It is correct!!
Step-by-step explanation:
Answer:
$3743.43
Step-by-step explanation:
The amount is given by the formula ...
A = Pe^(rt)
where P is the principal, r is the annual rate compounded continuously, and t is the number of years. Filling in the values, we get ...
A = $1600·e^(0.0425·20) = $1600·e^0.85
≈ $1600·2.33964685 ≈ $3743.43
The amount in the account will be $3743.43.
0.000000109 in scientific notation will look as it follows:
1.09 * 10^-7
or
<span>
1.09 E-7
It's the same as 1.09 * (-10000000)
I hope it'll give you some clue of scientific notation with decimals.</span>
<u><em /></u>Subtracting a negative number really means to add it
Here's addition:
(1) + (1) = 2
(1) + (-1) = 0
(-1) + (-1) = -2
(-1) + (1) = 0
Here's subtraction:
(1) - (1) = (1) + (-1) =0
(1) - (-1) = (1) + (1) = 2
(-1) - (-1) = (-1) + (1) = 0
(-1) - (1) = (-1) + (-1) = -2
Here's your problem specifically:
(5/10) - (-8/10)
(5/10) + (8/10)
*since they have the same denominator, that stays the same, and you only have to add up numerators
(5 + 8)/10
13/10
<u><em>answer is 13/10 . . . it's positive</em></u>
The answer is :
1. Yes,
2. Yes,
3. No,
4. Yes,
