Suppose $500 is invested at 6% annual interest compounded twice a year. When will the investment be worth $1000.

Nataly_w [17]

Answer:

Step-by-step explanation:

$V=P(1+r/c)^{(ct)}\\ \\ V=P(1+.06/2)^{(2t)}\\ \\ 1000=500(1.03)^{(2t)}\\ \\ (1.03)^{2t}=2\\ \\ 2t=ln2/(ln1.03)\\ \\ t=ln2/(2ln(1.03))\\ \\ t\approx 11.7 years$

Emelia measures the weight of a rock to be 30 grams. The actual weight of the rock is 24 grams. Determine Emelia's percent error

Shalnov [3]

Answer: 25%

Step-by-step explanation:

Given

Emelia measures the weight of the rock to be 30 gm

The actual weight was 24 gm

Percentage error is given by

$\Rightarrow \dfrac{\text{Deviation }}{\text{Actual value}}\times 100$

Insert the values

$\Rightarrow \dfrac{30-24}{24}\times 100\\\\\Rightarrow \dfrac{6}{24}\times 100\\\\\Rightarrow 25\%$

Therefore, the percentage error is 25%.
