I dont know the answer but all I know is that dude broke as heck
Answer:
see explanation
Step-by-step explanation:
The value of the discriminant informs about the nature of the roots of a quadratic function.
The discriminant Δ = b² - 4ac
• If b² - 4ac > 0, then roots are real and distinct
• If b² - 4ac = 0, then roots are real and equal
• If b² - 4ac < 0, then the roots are not real
Hence for b² - 4ac = - 8, then roots are not real
Answer:
a = 12 years
Step-by-step explanation:
Mark is 6 years older than his brother Sam. Now, we are asked to represent Sam’s age by a. This means that if Sam is a years old, Mark is (a + 6) years old.
The sum of their ages is 30, this means that when we add their ages together, we get the sum of thirty.
Mathematically this means a + a + 6 = 30
2a + 6 = 30
This is the equation needed to get a. To get a , we proceed to solve the equation to completion.
2a = 30 - 6
2a = 24
a = 24/2
a = 12
The definition of log is by the equivalence:
means
where b>0 and b ≠ 1.
a.
<span> is not a logarithmic function because the base is greater than 0.
False: By definition, the base of a log MUST be greater than zero but cannot equal one.
b. </span>
<span> is not a logarithmic function because the base is a square root.
False: sqrt(3) is a positive number not equal to one, so it is a legitimate base.
c. </span>
<span>is not a logarithmic function because the base is equal to 1.
True. Log cannot have a base of one, by definition.
Recall the definition of log where b^y=x. If b=1, b^y will also equal 1, so cannot equal x which has a domain of 0<x< ∞
d. </span>
is not a logarithmic function because the base is a fraction.
False, because 3/4 is a legitimate base, just like any other positive number other than one.
