Answer:
Option (B)
Step-by-step explanation:
Given sequence is 45, 135, 405, 1215, 3645..........
Since it's a geometric sequence,
Common ratio of each successive term to the previous term
r = 
First term of the sequence 'a' = 45
Explicit formula of a geometric sequence will be,
Recursive formula of this sequence will be,
, 
Therefore, Option (B) will be the answer.
2x² + 3x -8 = 0
a = 2 , b = 3 , c = -8
So..
D = b²-4ac = 9 + 64 = 73
for bigger solution , use x = -b + √D / 2a
For smaller solution, use x = -b - √D / 2a
So
= -3 + √73 / 2. 2
= 1/4 (√73 -3)
Hopefully helpfull.. ^_^
we know that
the speed's formula is equal to
in this problem we have
Substitute the values in the formula
therefore
<u>the answer is</u>
Answer:
C. The function is increasing when x > 0.
Step-by-step explanation:
Answer:
47 hours
$517
Step-by-step explanation:
M8 T9 W9 T8 F0 S8 S5
From the information above :
Total hours worked last week :
(8 + 9 + 9 + 8 + 0 + 8 + 5) = 47 hours
Rate = $11 / hour
Last week earning :
Total hours worked * rate per hour
47 * $11
= $517
