Answer:
the answer is 7.53 * 10-10
Step-by-step explanation:
The initial amount is $650. The $400 is deposited in Account 1 with 3.5% annual simple interest. The $250 is deposited in Account 2 with 3.5% interest compounded monthly.
n = 2 years
Account 1: Simple Interest
F = P (1+rn)
= 400 (1 +(0.035*2))
= $428
Account 2: Compound Interest
F = P (1+i)^n
= 250 ( 1+0.035)^2
F = 267.81
Total money after 2 years = $428 + $267.81
T = $695.81
Answer:
They are equal
Step-by-step explanation:
All the sides are equal, because you use the pythagoreon theorem to find out that all the sides are equal.
Solve the following system using elimination:
{3 a + 4 b = 2 | (equation 1)
{5 a + 9 b = 1 | (equation 2)
Swap equation 1 with equation 2:
{5 a + 9 b = 1 | (equation 1)
{3 a + 4 b = 2 | (equation 2)
Subtract 3/5 × (equation 1) from equation 2:
{5 a + 9 b = 1 | (equation 1)
{0 a - (7 b)/5 = 7/5 | (equation 2)
Multiply equation 2 by 5/7:
{5 a + 9 b = 1 | (equation 1)
{0 a - b = 1 | (equation 2)
Multiply equation 2 by -1:
{5 a + 9 b = 1 | (equation 1)
{0 a+b = -1 | (equation 2)
Subtract 9 × (equation 2) from equation 1:
{5 a+0 b = 10 | (equation 1)
{0 a+b = -1 | (equation 2)
Divide equation 1 by 5:
{a+0 b = 2 | (equation 1)
{0 a+b = -1 | (equation 2)
Collect results:
Answer: {a = 2
{b = -1
4(2m-1)=16
8m-4=16
8m=20
m=20/8
=2.5
Hope this helps. Just ask if you need a better explanation.
