Answer:
Explanation:
The missing equation is:

You are given:
- Ta = the temperature surrounding the object = 73ºF
- T₀ = the initial temperature of the object = 204ºF
- t = 2.5 min
- T after 2.5 min = 180ºF
Question 1: Find the the value of k.
Substitute the data into the equation and solve for k:

Question 2: Find the Fahrenheit temperature of the cup of water, to the nearest degree, after 4 minutes.
Subsititute into the formula and compute:

-17 -35
-3 -3
-2 0
-31 -87
17 57

Answer:
Trinomial can not be factored
Step-by-step explanation Equation at the end of step 2 : 4x 2 - 2x - 1 = 0 Step 3 : Parabola, Finding the Vertex : 3.1 Find the Vertex of y = 4x 2-2x-1 Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum)
Answer:
The roots are
<h3>

</h3>
Step-by-step explanation:
9x² + 54x + 82 = 0
Using the quadratic formula
That's
