Answer:

(a) -- the correct choice is highlighted

Step-by-step explanation:

The units of specific heat tell you what quantities make up the ratio.

$\dfrac{390\text{ J}}{1\text{ kg$\cdot^\circ$C}}=\dfrac{-12.0\text{ J}}{0.012\text{ kg}\cdot\Delta T}\\\\\Delta T=\dfrac{-12.0}{0.012\cdot390}\ ^\circ\text{C}\approx-2.56\text{ $^\circ$C}$

The temperature will decrease by 2.56 C.

Nicole deposited $2,000 at 6% simple interest. How long will it be before she has $2,600 in her account?

Kryger [21]

FV=PV(1+r)ⁿ

FV=Future Value, or the $2,600 that you want.
PV=Present Value, or the value that you are depositing.
APR: .06

2,600=2,000(1.06)ⁿ
2,600=2120ⁿ
It would take about a year for Nicole to get $2600.
