How do you find the phase shift of the trig function y=4sin(pieX+2)-5
max2010maxim [7]

The phase shift is the value of the angle when the variable
in the angle is zero.

The angle in the sin function in this equation is (pi X + 2).

When the variable 'X' is zero, the angle is  2 .

So the phase shift of this sin function is  2  (of whatever
the unit of the angle is ... 2 degrees, 2 radians, etc.)

Jim is showing his work in simplifying (−8.5 + 6.1) − 1.3.
dexar [7]

9514 1404 393

Answer:

  In step 4, Jim's answer is incorrect.

Step-by-step explanation:

In step 1, Jim swaps the order of addends using the commutative property of addition.

In step 2, Jim uses the distributive property to factor -1 from the final two terms. (The associative property lets Jim move parentheses.)

  6.1 +(-8.5 -1.3) . . . associative property

  6.1 +(-1)(8.5 +1.3) . . . distributive property

In step 3, Jim has used the properties of real numbers to form the sum of two of them.

In step 4, Jim wrote an answer of 1.1, when the answer should have been -3.7. Jim's answer is incorrect.

__

The descriptive statements about steps 2 and 4 are both true.

\displaystyle  \\ 
\texttt{Notations: } \\ 
P = \texttt{pressure} \\ 
V = \texttt{volume} \\ 
T = \texttt{absolute temperature} \\  \\ 
\texttt{We use the formula: }~   \frac{P \times V}{T} = \texttt{constant} \\  \\ 
\frac{P_1 \times V_1}{T_1} = \frac{P_2 \times V_2}{T_2}  \\  \\ 
P_1 = P_2 \\  \\ 
\Longrightarrow~~\frac{V_1}{T_1} = \frac{V_2}{T_2}\\\\ 
\Longrightarrow~V_2 =\frac{V_1 \times T_2}{T_1}=  \frac{0.2~m^3 \times 533^oK}{333^oK}=\frac{106.6}{333}= 0.3(201)\approx \boxed{0,32~m^3}
