(1 point) The temperature,H, in degrees Celsius of a cup of coffee placed on the kitchen counter is given by $H=f(t)$ where t is in minutes since the coffee was put on the counter. (a) Is $f'(t)$ positive or negative? $\square $ ? (Be sure that you are able to give a reason for your answer.) (b) What are the units of $f'(35)$ $\square $ help (units) Suppose that $\vert f'(35)\vert =1.5$ and $f(35)=75$ Fill in the blanks (including units where needed)and select the appropriate terms to complete the following statement about the temperature of the coffee in this case. At $\square $ minutes after the coffee was put on the counter, its $\square $ $\square $ and will $\square $ by about v is "? $\square $ in the next 15 seconds.
