The figure below shows three uniform objects: a rod with m1 = 7.00 kg, a right triangle with m2 = 3.70 kg, and a square with m3

navik [9.2K]

The answer is

G = [m1(veca1a2) + m2 (veca3a4) + m3veca5a6)] / (m1 + m2 + m3)

G= m1x5 + m2 x 4sqrt (2) + m3x 3sqrt (2) / 16 = 35 +4 x 3.7x sqrt (2) + 5.3 x3 4sqrt (2) / 16 =35 + 36<span> sqrt (2) / 16
G = 53.09

You borrowed 43,800 at a SIMPLE interest rate of 4.8%. If you pay it back in 2 years, how much

Naddik [55]

Answer:

I = $4204.8

Step-by-step explanation:

Given that,

Principal, P = $43,800

Interest rate = 4.8%

Rate = 2 years

We need to find the interest that is paid back. We know that, simple interest is given by :

$I=\dfrac{PRT}{100}$

Put all the values,

$I=\dfrac{43800\times 4.8\times 2}{100}\\\\=\$4204.8$

So, the required interest is equal to $4204.8 .
