What is the midpoint of the x-intercepts of f(x) = (x – 2)(x – 4)? A)(–3,0)
B)(–1,0)
C)(1,0)
D)(3,0)
What is the midpoint of the x-intercepts of f(x) = - 1

Answers

Answer 1
Answer:

Answer:

The correct option is D.

Step-by-step explanation:

The given function is

f(x)=(x-2)(x-4)

From the given graph it is clear that x-intercepts of the graph are (2,0) and (4,0).

The midpoint of x-intercepts is

Midpoint=((x_1+x_2)/(2),(y_1+y_2)/(2))

Midpoint=((2+4)/(2),(0+0)/(2))

Midpoint=((6)/(2),(0)/(2))

Midpoint=(3,0)

The midpoint of x-intercepts is (3,0). Therefore the correct option is D.
Answer 2
Answer: The x-intercepts are readily identified on the graph:  (2,0) and (4,0).  The midpoint of a line connecting those 2 points would be (3,0).

Log 5 plus log 2 equals?

log5 + log2 =

Answers


The sum of logs = the log of the product .

     log(5) + log(2)  =  log(5·2)  =  log(10)

If these are all logs to the base 10, then  log(10) = 1

       log(5) + log(2)  =  1

Let's try it out !

According to my calculator ...

             log(5)  =  0.69897...

             log(2)  =  0.30103...

Log(5) + log(2)  =  0.99999...          yay !        not bad

The solution of the equation log5 + log2 using the properties of Logarithm is log(10) or 1.

Logarithms are used to solve exponential equations by converting them into simpler forms.

A number that represents the power to which a fixed number (the base) must be increased in order to get a specific number is called as logarithm.

The property of logarithms states that:

log(a) + log(b) =  log(ab).

Applying this property, we get:

log5 + log2

= \log(5*2)

= log(10)

Logarithm base 10 (log) gives the power to which 10 must be raised to obtain the given value. So, log(10) represents the exponent required to obtain 10, which is 1.

Thus, the solution of  log5 + log2 is equal to log(10) or 1.
