Answer:
A
Step-by-step explanation:
If you simplify the equation you are left with 5 = -1, which is an untrue statement. Therefore, no matter what value you use for x you will always be left with 5 = -1.
Length (2, 6) to (-4, 6) is sqrt((x2 - x1))^2 + (y2 - y1)^2) = sqrt((-4 -2)^2 + (6 - 6)^2) = sqrt((-6)^2 + 0) = 6
Length (2, 6) to (-4, 4) is sqrt((-4 - 2)^2 + (4 - 6)^2) = sqrt((-6)^2 + (-2)^2) = sqrt(36 + 4) = sqrt(40) = 2sqrt(10) units
Length (-4, 6) to (-4, 4) is sqrt((-4 - (-4))^2 + (4 - 6)^2) = sqrt(0^2 + (-2)^2) = 2
Therefore, the length of the longest side is 2sqrt(10) units
Step-by-step explanation:
Logarithm is basically the exponent - also called power - to which a base must be raised to produce a given number.
Mathematically, it can be displayed as:
is the logarithm of
to the base
, if
, in which case we write

Lets take the first example,

as

Therefore, 4 is the logarithm of 16 to base 2.
Lets take the second example,



- Logarithmic functions are basically inverse of exponents.
Here is how they are related to each other:
Logarithm → Exponent
→ 
- Logarithms are helpful in displaying large number.
