Answer:
Step-by-step explanation:
The given equation is 
.
We take logarithm of both sides to base 2 to get:
Apply the power rule of logarithms to get:
We now apply the change of base formula:
To the nearest thousandth,
Answer: –4rx –15x^2 + 8r + 26x
Step by step:
= 2x + −15x^2 + 24x + −4rx +8r
= (−4rx) + (–15x^2) + (8r) + (2x+ 24x)
= –4rx + –15x^2 + 8r + 26x
Answer:
19
Step-by-step explanation:
Rearranging the number in ascending order,
12,15,17,19,19,20,24,26
Median = The average of the 4th and 5th number
C = 2πr
17 = 2(3.14)(r)
17 = 2(3.14r)
17 = 6.28r
6.28 6.28
2.71 ≈ r
9514 1404 393
Answer:
- 3 big bucks
- 6 little bucks
- 17 does
Step-by-step explanation:
Let B, L, D represent the numbers of big bucks, little bucks, and does, respectively.
B + L + D = 26 . . . . . . total bagged
D = 5 + 2L . . . . . . . . . 5 more does than twice the number of little bucks
B = L/2 . . . . . . . . . . . . half as many big bucks as little bucks
__
We can substitute for B and D in the first equation:
L/2 + L + (5 +2L) = 26
7/2L = 21 . . . . . . . . . . . . . subtract 5, collect terms
L = 6 . . . . . . . . . . . . . . . . . multiply by 2/7
D = 5 + 2·6 = 17
B = 6/2 = 3
The party bagged 3 big bucks, 6 little bucks and 17 does.
