Identify intervals on which the function is increasing, decreasing, or constant.
tigry1 [53]
G ( x ) = 2 - ( x - 7 )²
g ( x ) = 2 - ( x² - 14 x + 49 )
g ( x ) = 2 - x² + 14 x - 49
g ( x ) = - x² + 14 x - 47
The maximum of the function is at:
x= - b / 2 a
x = - 14 / ( - 2 ) = 7
Therefore the function is increasing form x ∈ ( - ∞, 7 ) and decreasing for x ∈ ( 7, +∞ ).
Answer:
C.   increasing, x < 7; decreasing x > 7.

The sale price of a spring break vacation package was $209.99 the travel agent said by booking early you saved $20.00. Find the
prisoha [69]

Answer:

<em></em>\%\ decrease =  9.52\%<em></em>

<em></em>

Step-by-step explanation:

Given

Sales\ Price = \$209.99

Saved = \$20.00

Required

Determine the %decrease

First, we need to determine the amount paid

Amount = Sales\ Price - Amount\ Saved

Amount = \$209.99 - \$20.00

Amount = \$189.99

The percentage decrease is the calculated as follows:

\%\ decrease = -100\% * \frac{Final - Initial}{Initial}

In this case;

Initial = Sales\ Price = \$209.99

Final = Amount\ Paid = \$189.99

So; we have:

\%\ decrease = -100\% * \frac{189.99 - 209.99}{209.99}

\%\ decrease = -100\% * \frac{-20}{209.99}

\%\ decrease = 100\% * \frac{20}{209.99}

\%\ decrease =  \frac{2000\%}{209.99}

\%\ decrease =  9.52426306015\%

<em></em>\%\ decrease =  9.52\%<em> (Approximated)</em>
