Answer:
D
Step-by-step explanation:
Product means multiplication. Since we are multiplying 6s to (-2s²+4s-10), we will use the distributive property to solve.
6s(-2s² + 4s - 10)
-12s³ + 24² - 60
Best of Luck!
To find the axis of symmetry you must first find the vertex of the parabola. The formula for vertex is -b/2a. So the vertex has a "x" coordinate at 4/2 or 2. so the axis of symmetry is the vertical line x = 2

Step-by-step explanation:
Newton's cooling model is:
Where
t is the time in hours
is the ambient temperature
is the initial temperature of the body
We know that:
Then after 7 hours the temperature of the liquid will be:
Answer:
+ 2 for the top row and -10 from bottom row
Step-by-step explanation:
-2 + 2 = 0
0 + 2 = 2
2 + 2 = 4
15 - 10 = 5
5 - 10 = -5
-5 - 10 = -15
