What is the maximum value of the function f(x)= 12 - 3sin (3pi/2 x)

The lowest value of sinα is -1.

When x=1, you get:

$f\left( x \right) =12-3\sin { \left( \frac { 3 }{ 2 } \pi \right) } \\ \\ =12-3\left( -1 \right) \\ \\ =12+3\\ \\ =15$

So the maximum value of the function is 15.

F(x) = 12 - 3sin(3π/2x)
f(x) = 12 - 3sin(9.42/2x)

Can anyone figure this out for me please? It would be greatly appreciated.

Check the picture below.

now, to get how much is the area of the tiled section, we simply get the area of the whole pool, 53x26, which includes the tiles, and then subtract the area without the tile, the rectangle in the middle, and what's leftover, is the area of the tiled area.

$\bf 53-4\frac{1}{2}-4\frac{1}{2}\implies 53-9\implies \boxed{42}
\\\\\\
26-4\frac{1}{2}-4\frac{1}{2}\implies 26-9\implies \boxed{17}
\\\\\\
\textit{so the area of the rectangle in the middle is}\implies 42\cdot 17\implies 714
\\\\\\
\textit{and the area of the whole pool is}\implies 53\cdot 26\implies 1378$

$\bf \stackrel{\textit{area of the whole pool}}{1378}~~-~~\stackrel{\textit{area of the middle rectangle}}{714}\implies \stackrel{\textit{area of the tiles}}{664}\\\\
-------------------------------\\\\
\textit{we know that is }\$5\frac{1}{2}\textit{ for a foot of tile, then}\stackrel{\textit{price of the tiles}}{664\cdot 5\frac{1}{2}}\implies 3652$

Joseph pays $20 for his base phone plan in addition to the $0.23 per text. Micki pays $10 for her phne plan plus $0.15 per text.

Nostrana [21]

Not really Specific in asking in what way you want it answered... So here is what Im able to understand.

Function

Joseph : 20 + .23x = y

Micki : 10 + .15x =y

Hope this is what your asking...

A train is traveling at 60 mph. If the rate of speed increases 4 mph each hour,

Alenkasestr [34]

Answer:

B) 5 hours

Step-by-step explanation:

First, find the amount of mph between 60 and 80:

80 - 60

= 20 mph

Since the speed increases 4 mph per hour, we can find how long it will take to get to 80 mph by dividing 20 by 4:

20/4

= 5

So, the correct answer is B, 5 hours

There is a strong, negative relationship between outside temperature and snow shovel sales. As x increases, y decreases.
