What is the missing constant term in the perfect square that starts with x 2 +14x
1 answer:
Okay, let me explain.
Basically, you need to complete the square.
So you have, +14x+__________ to equal a perfect square.
Your middle term is 14. So, what you need to do is divide fourteen by 2 which equals 7. What does 7*7 or 7 squared equal? It equals 49.
The missing constant term is 49.
I hope this helped; feel free to ask any follow-up questions.

Answer: (B) 3 times as fast
<u>Step-by-step explanation:</u>
rate of change is the "slope" between the given interval.
f(x) = 125(.9)ˣ
f(1) = 125(.9)¹
= 112.5
f(5) = 125(.9)⁵
= 73.8
********************
f(11) = 125(.9)¹¹
= 39.2
f(15) = 125(.9)¹⁵
= 25.7
********************
The rate of change from years 1 to 5 is approximately 3 times the rate of change from years 11 to 15.
