Answer:

Minimum value of f(x) = -1.

Step-by-step explanation:

We convert it to vertex form:

x^2 - 6x + 8

= (x - 3)^2 - 9 + 8

= (x - 3)^2 - 1

The minimum value occurs when (x - 3)^2 = 0 because a square has a minimum value of zero ( it cannot be negative for real values of x).

So the function has a minimum value of -1.

Answer:

Step-by-step explanation:

<A = 180 - (63+90)

<A = 180 - 63 - 90

<A = 180 - (63+45+<B )

<A = 180 -63 -45 -<B

Which expression is equivalent?

gregori [183]

The correct option is: Option (C) $log_3c - log_{3}9$

Explanation:
It is the property of log that if it contains the fraction, it can be expressed as the difference of the log of numerator and the log of denominator.

The general form is:
$log( \frac{x}{y} ) = log(x) - log(y)$

Hence the correct answer is $log_3c - log_{3}9$ .

Please choose the answer that describes the scientific notation for 5,098,000.

avanturin [10]

Scientific notation is the representation of a number in a power of ten, with a sequence of digits placing the comma after the first digit, and the power or then that is mathematically consistent with the number. For example 400 is 4.00 * 10^2; 3100 is 3.100 * 10^4; 13421 = 1.3421 * 10 ^4. It is important that you have only one digit before the comma. So, 5,098,00 is 5.098 * 1,000,00 = 5.098 * 10^6. The answer is the option c. 5.098 * 10^6.
