5. Answer 1
6. Answer 4
7. Answer 2
Answer:
a. k = 27
b. k = 216
c. k = 0.216
Step-by-step explanation:
The value of the scale factor can be given by the following formula:
where,
Initial Volume = 8 cubic units
a.
Final Volume = 216 cubic units
Therefore,
<u>k = 27</u>
<u></u>
b.
Final Volume = 1 cubic units
Therefore,
<u>k = 216</u>
<u></u>
c.
Final Volume = 1000 cubic units
Therefore,
<u>k = 0.216</u>
Answer:
0.93
Step-by-step explanation:
Answer:
(1, 0 )
Step-by-step explanation:
using the rule of logarithms
x = n ⇒ x = , then
y = (x + 2) - 1
to find the zero let y = 0 , that is
(x + 2) - 1 = 0 ( add 1 to both sides )
(x + 2) = 1 , then
x + 2 = = 3 ( subtract 2 from both sides )
x = 1
the zero is (1, 0 )
