Mathematics

Travka [436]2 years ago

Answer:

If the x-6 is all under the sqrt, the last answer is right:

6<= x <= infinity

If only x is under the sqrt and - 6 is NOT under the sqrt, then:

0 <= x <= infinity is the correct answer.

Step-by-step explanation:

You can look at the equation and or graph to determine the domain of a function. The domain is all the x's that may go into the equation or all the x's on the graph of the function. Inside of a squareroot symbol the number inside there must be positive. While considering the equation, only x's that keep that inside positive can be used.

For sqrt(x-6), x has to be 6 or bigger.

For sqrt(x) - 6, x has to be 0 or bigger.

Iteru [2.4K]

Answer:324

Step-by-step explanation:

int i = 42.7;            /* konwersja z double do int */

float f = i;             /* konwersja z int do float */

double d = f;            /* konwersja z float do double */

unsigned u = i;          /* konwersja z int do unsigned int */

f = 4.2;                 /* konwersja z double do float */

i = d;                   /* konwersja z double do int */

char *str = "foo";       /* konwersja z const char* do char*  [1] */

const char *cstr = str;  /* konwersja z char* do const char* */

void *ptr = str;         /* konwersja z char* do void* */

Need help please...............................
Hunter-Best [27]
Note that the side adjacent to angle XYZ is given (6 cm) and that the hypo is also given (15 cm).  Thus, cos XYZ = adj / hyp = 6 cm / 15 cm  = 2/5 = 0.4.

XYZ is then  arc cos 0.4.  Use the arccos function on your calculator to determine XYZ and give XYZ in both degrees and radians.

What is the sum of a 12-term arithmetic sequence where the last term is 13 and the common difference is -10?
Y_Kistochka [10]
\bf n^{th}\textit{ term of an arithmetic sequence}\\\\&#10;a_n=a_1+(n-1)d\qquad &#10;\begin{cases}&#10;n=n^{th}\ term\\&#10;a_1=\textit{first term's value}\\&#10;d=\textit{common difference}\\&#10;----------\\&#10;n=12\\&#10;d=-10\\&#10;a_{12}=13&#10;\end{cases}&#10;\\\\\\&#10;a_{12}=a_1+(12-1)d\implies 13=a_1+(12-1)(-10)&#10;\\\\\\&#10;13=a_1-110\implies \boxed{123=a_1}

\bf \\\\&#10;-------------------------------\\\\&#10;\textit{sum of a finite arithmetic sequence}\\\\&#10;S_n=\cfrac{n}{2}(a_1+a_n)\qquad &#10;\begin{cases}&#10;n=n^{th}\ term\\&#10;a_1=\textit{first term's value}\\&#10;a_n=\textit{value of the }n^{th}\ term\\&#10;------------\\&#10;n=12\\&#10;a_1=123\\&#10;a_{12}=13&#10;\end{cases}&#10;\\\\\\&#10;S_{12}=\cfrac{12}{2}(a_1+a_{12})\implies S_{12}=\cfrac{12}{2}(123+13)

and surely you know how much that is.
