evablogger [386]

Answer:

490,000

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.

2. A sphere has surface area 16π. Find the radius of the sphere.
KiRa [710]

Answer:

The answer to your question is: 2.29 units

Step-by-step explanation:

Data

Volume = 16π

radius = ?

Formula

V = \frac{4}{3}π r^{3}

Process

                         16 π =  \frac{4}{3}π r^{3}

                         \frac{16(3)}{4} = r^{3}

                         r³ = 12

                        r = 2.29
