Answer:
log3 81 = 4
Step-by-step explanation:
Convert the exponential equation to a logarithmic equation using the logarithm base (3)(3) of the right side (81)(81) equals the exponent (4)(4).
log3(81)=4
or
you can remember this
loga Y= X
so, a^x =y
Answer: 70 meters.
Step-by-step explanation:
Observe the figure attached.
The distance between the walls is:
<em />
Both triangles are right triangles. Therefore, you can calculate the distance between the walls as following:
- Calculate the distance AD:
- Calculate the distance AE:
Therefore the distance between the walls is:
Step-by-step explanation:
C(500)=65×500+850
=32500+850
=33350
The required answer
Correct Answer:
Second Option
Solution:
A geometric series converges when the value of its common ratio is between -1 and 1. Else the series will diverge. So we find the common ratio for each of the given options, the series with common ratio between -1 and 1 will be converging series.
For first option, common ratio = 1/3 divided by 1/9 = 3
Common ratio is not between -1 and 1, so this series is diverging.
For second option, common ratio = 1/2 divided by 1 = 1/2
Since the common ratio is between -1 and 1, this series is converging.
For third option, common ratio = -4
This series is also diverging.
For Fourth option, common ratio = 2
This series is also diverging.
