Answer:
f(x) = 8 (x + ¼)² − ½
Step-by-step explanation:
f(x) = 8x² + 4x
Divide both sides by 8.
1/8 f(x) = x² + 1/2 x
Take half of the second coefficient, square it, then add to both sides.
(½ / 2)² = (1/4)² = 1/16
1/8 f(x) + 1/16 = x² + 1/2 x + 1/6
Factor the perfect square.
1/8 f(x) + 1/16 = (x + 1/4)²
Multiply both sides by 8.
f(x) + 1/2 = 8 (x + 1/4)²
Subtract 1/2 from both sides.
f(x) = 8 (x + 1/4)² − 1/2
Answer:
<em>The decay rate 'm' is 0.25</em>
Step-by-step explanation:
As given,
Average Life time of New cell phone = 4 years
Lifetime of phone = L = ?
<em>L</em><em> is a random variable defining lifetime of a cell phone.</em>
L∼
Exponential (m)
Mean of Exponential Distribution =
As, they follow exponential distribution, so to find decay rate , we simply can write it as :
= 4
or
<em><u>m=0.25</u></em>
L∼
Exponential (0.25)
<em>The decay rate is 0.25</em>
Answer:
The nautical mile is based on the Earth's longitude and latitude coordinates, with one nautical mile equaling one minute of latitude.
Step-by-step explanation:
Answer:
Neither
Step-by-step explanation:
The +10% and -10% cancel each other out, so neither is the answer.
