What is the domain of the function graphed below?

Mathematics

Answer:

x < 7

Step-by-step explanation:

the domain is the number range or interval of x the function is defined for to generate a y-value.

the graph shows that the y-values continue with x-values to the right up to but not including 7 (the empty dot says "excluding"). and with x- values to the left to negative infinity.

x=-1 is not a problem, because while for the left part of the function it is not included, but for the right part it is.

so, it is fully defined for all x < 7.

. a thin plate made of iron is located in the xy-plane. the temperature t in degrees celsius at a point p(x,y) is inversely prop
harkovskaia [24]

The level of the curves are all the eclipses with the major axis.

             100                        50          1

a2 =       ------  - 1   ,   b2 =   -------  -   -----

               C                            C           2

Given that:

               100

T(x, y) = ------------

               1 + x2 + y2

This implies that the level curves of a function(f) of two variables relate to the curves with equation f(x, y) = c

where c is the constant.

                 100

        C = ------------                          ----- (1)

             1 + x2 + y2

By cross multiply

C (1 + x2 + y2) = 100

1 + x2 + y2 = 100/C

       

               100

x2 + y2= ---------  - 1                    -----(2)

                 C

From (2); let's assume that the values of c > 0 likewise c < 100, then the interval can be expressed as 0 < c <100.

Now,

(x)2           (y)2

------   +     ---------------

100            50          1

------  - 1     -------  -   -----

C                C           2

This is the equation for the  family of the eclipses centered at (0,0) is :

x2/a2 + y2/b2 = 1

             100                        50          1

a2 =       ------  - 1      b2 =   -------  -   -----

              C                            C           2

Therefore; the level of the curves are all the eclipses with the major axis:

             100                        50          1

a2 =       ------  - 1      b2 =   -------  -   -----

              C                            C           2

 and a minor axis   which satisfies the values for which 0< c < 100.

The sketch of the level curves can be see in the attached image below.

Write the equation of the circle with the given center and radius: (h,k)= (-4,6), r=7
mina [271]

Step-by-step explanation:

Equation of a circle in standard form is given as:

(x - h)^{2}  + (y - k)^{2}   =  {r}^{2} \\  \\  \therefore  \{x -( - 4) \}^{2}  + (y - 6)^{2}   =  {7}^{2}  \\  \\  \red{ \boxed{ \bold{\therefore  (x  +  4)^{2}  + (y - 6)^{2}   = 49}}} \\ is \: the \: required \: equation \: of \: circle.

Solve the inequality r-(-5)&gt;-2
Jet001 [13]

Answer:

r>-7

Step-by-step explanation:

Solving an inequality is similar to solving an equation. To solve for r, isolate it. Whatever you do to one side, do to the other. Remember that a negative and a negative equal a positive, thus one side of the inequality becomes r + 5. Then, subtract both sides by -5 to find the answer.

r-(-5) >-2\\r+5>-2\\r>-7
