Answer:
$449.77
Step-by-step explanation:
The balance in account 1 can be found using the simple interest formula.
A = P(1 +rt)
A = $300(1 +0.045·3) = $340.50
The balance for account 2 can be found using the compound interest formula.
A = P(1 +r)^t
A = $100(1.03)^3 = $109.27
__
Darla's total balance will be ...
$340.50 +109.27 = $449.77
Answer:
Option B.
{–9 + i√225 / 24, –9 – i√225 / 24}
Step-by-step explanation:
12a² + 9a + 7 = 0
Using formula method, the solutions to the equation can be obtained as follow:
Coefficient of a² (a) = 12
Coefficient of a (b) = 9
Constant (c) = 7
a = –b ±√(b² – 4ac) / 2a
a = –9 ±√(9² – 4 × 12 × 7) / 2 × 12
a = –9 ±√(81 – 336) / 24
a = –9 ±√(– 225) / 24
Recall
–225 = –1 × 225
Thus,
–9 ±√(– 225) / 24 = –9 ±√(–1 × 225)/24
Recall
√(–1 × 225) = √–1 × √225 = i√225
Thus,
–9 ±√(–1 × 225)/24 = –9 ± i√225/24
Therefore,
a = –9 ± i√225/24
a = –9 + i√225 / 24 or –9 – i√225 / 24
Therefore, the solutions to the equation are:
{–9 + i√225 / 24, –9 – i√225 / 24}
Answer:
Step-by-step explanation:
write the percent over 100
then simplify
Slope formula is y2-y1/x2-x1.
So if i plugged the numbers in, you receive
Simplified, this becomes
To make the slope equal 5, the numerator y-6 has to = -5 since there is a -1 denominator.
1-6 = -5 making the slope now,
since both the numerator and denominator is negative, the whole fraction becomes positive. This makes the slope equal
or 5
