D
Step-by-step explanation:
6.8 = (6/5)^x
6.8 = 1.2^x
x ln 1.2 = ln 6.8
x = ln 6.8 / ln 1.2

Step-by-step explanation:
The surface area of a sphere can be found using the formula
. Since the radius is 13 units, substitute r=13.

Without multiplying 3.14 for
, the answer is

Answer: is If something is a function, every x-value, only has one (1) y-value. If the line x = 0 intersects the graph in two points, there are to values for y (instead of one). Therefore the graph is not a function of x.
Step-by-step explanation: answer is A
Answer:
Option A
Step-by-step explanation:
For finding the greatest common factor of 20 and 38
We will have to make factors of both terms first,
So,
factors of 20:<u>2</u>*2*5
factors of 38=<u>2</u>*19
It can be seen that there is only one common factor between the factors of the two terms which is 2.
So the Greatest common factor of both the terms will be 2.
Hence, the correct answer is Option A ..
