A scientist is slowly heating a quantity of vinegar. Every 5 minutes, the temperature rises 2.3 Fahrenheit degrees. Write an equation that describes this situation.

Step-by-step explanation:

-Let t denote time and h(t) be the function that denotes the temperature after time t

-Also, let's take x°F to be the initial temperature of the vinegar.

Since, the temperature increases by 2.3°F every 5 minutes, we determine the rate of change per minute:

The situation can thus be expressed as:

bull

step-by-step explanation:

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
