Determine the range
To do this, we simply substitute the values of n in the given expression
So, we have:






Hence, the range is:

Answer:

Step-by-step explanation:
We are given the temperature inside the machine from startup until 10 seconds later, the formula is:

We want to know at what time t the temperature inside the machine will be equal to 128 °C.
So we set:


Now, we rearrange the equation to keep terms with t on the left hand side and terms without t on the right hand side

and we simplify:


now it's easy to solve for t:

And thus we arrive to the solution.
Answer:
84.
Step-by-step explanation:
96 / (7 + 5) + 19 * 4
Use order of operations (PEMDAS* ).
Perform the operation in the parentheses first:
= 96/12 + 19*4
Now the divide and multiplication:
= 8 + 76
and finally the add:
= 84.
