A linear function increases/decreases by a certain amount every year. As it changes 1500 over the first 5 years (300 per year) and 3000 over the next 5 (600 per year), this cannot be liner

A quadratic function goes down then up, or vice versa. This consistently goes up, and is therefore not quadratic

A trigonometric function also goes up and down, so it is not trigonometric

Therefore, as an exponential function can keep going up at different rates over time, this is an exponential function

A pot of stew is placed on a stove to heat. The temperature of the liquid reaches 170°F, and then the pot is taken off the burne

Answer:

$T =84.7\°F$

Step-by-step explanation:

Newton's cooling model is:

$T(t) =T_0 + (T_i-T_0)e^{-kt}$

Where

t is the time in hours

$T_0$ is the ambient temperature

$T_i$ is the initial temperature of the body

$k=0.34$

We know that:

$T_0=76\°F$

$T_i=170\°F$

Then after 7 hours the temperature of the liquid will be:

$T(7) =76 + (170-76)e^{-0.34(7)}$

$T =84.7\°F$
