[tex]\left( x-2\right)^{2} +\left( y-6\right)^{2} =12[/tex]

Step-by-step explanation:

Formula ………………………………………………………………………

The equation of a circle with center (a , b) and radius r is :

[tex]\left( x-a\right)^{2} +\left( y-b\right)^{2} =r^{2}[/tex]

===================

Now ,let’s apply what we have learnt:

The equation of the circle with center (a , b) = (2 , 6) and radius r = 2√3 is :

[tex]\left( x-2\right)^{2} +\left( y-6\right)^{2} =\left( 2\sqrt{3} \right)^{2}[/tex]

[tex]\Longleftrightarrow \left( x-2\right)^{2} +\left( y-6\right)^{2} =12[/tex]

[tex]\text{Note :} \left( 2\sqrt{3} \right)^{2} =2^{2}\times \sqrt{3}^{2} =4\times3=12[/tex]

The cost in dollars of making x items is given by the function C(x) = 10x + 900. The fixed cost is 900 dollars. C(25 ) = $1150. The Range is 250.

The function is a type of relation, or rule, that maps one input to specific single output.

The cost in dollars of making x items is given by the function

C(x) = 10x + 900

a. The fixed cost is determined when zero items are produced. Find the fixed cost for this item.

The fixed cost

C(0) = 10(0) + 900

       = 0 + 900

       = $900

b. What is the cost of making 25 items?

C(25) = 10(25) + 900

       = 250 + 900

       = $1150

Therefore, C(25 ) = $1150

c. Suppose the maximum cost allowed is $1900. What are the domain and range of the cost function, C(x)?

The domain is the set of values for which the given function is defined.

Range = Maximum value of the data set - Minimum value of the dataset

Range = C(25 ) - C(0)

           = 1150 - 900

           = 250

Answer:

( -4 , 3 )

Step-by-step explanation:

Knowing that "y" is the line going up and down and "x' is the line going left to right.

Quadrant | = ( + , + )

Quadrant || =  ( - , +)

Quadrant ||| = (- , - )

Quadrant |v = ( + , - )

Refer to image below if needed.

Hence, from the given we can conclude the following:

Quadrant || =  ( - , +)

( x , y )

x = -4

y = 3

Thus, we have:

( -4 , 3 )

Therefore, the correct answer is ( -4 , 3 )

Step-by-step explanation:

first of all, remember. when dividing by a fraction, this is the same as multiplying by the upside-down fraction.

and all these signs (including the fraction sign) stand for divisions and really do the same thing and can be exchanged with each other : "/", "÷", ":"

and when writing a number like 4 1/2, it is a shortcut and means actually (4 + 1/2).

so,

4 1/2 ÷ 1/2 = 4 1/2 × 2/1 = 4 1/2 × 2 = (8/2 + 1/2)×2 =

Answer:

it has something to do with the part circle it's a 180%

Answer: 26.93 square inches

Step-by-step explanation:

first let us find the area of the rectangle shape

rectangle area = length times width

rectangle area = 2 times 11

rectangle area = 22 inches

now let us do the half circle area

half circle area = 1/2(πr^2)

half circle area ~ 1/2 times 3.14(1)^2

half circle area ~ 1/2 times 3.14^2

half circle area ~ 1/2 times 9.8596

half circle area ~ 4.9298

now let’s add the half circle area and the rectangle area to get our total area

total area ~ 4.9298 + 22

total area ~ 26.9298

total area ~ 26.93

26.93 square inches is the total area rounded to the nearest hundredth.

This is NOT a function

[tex]18*(7*(-3))=18*7+18*(-3)\\18*-21=126 - 54\\-378 \neq 72[/tex]

LHS [tex]\neq[/tex] RHS

Answer :

To verify an equation, we need to see if the LHS = RHS.

Equation [tex]\downarrow[/tex]

[tex]18\times(7\times(-3))=18\times7+18\times(-3)[/tex]

Let's solve the left hand side (LHS) first.

[tex]18\times(7\times(-3))\\= 18 \times (-21)\\=\underline{ -378}[/tex]

Now, let's solve the right hand side (RHS).

[tex]18\times7+18\times(-3)\\= 126 - 54\\=\underline {72}[/tex]

But,

[tex]\boxed{-378 \neq 72}[/tex]

We can see that the LHS doesn't match or isn't equal to the RHS.

Hence, we can say that LHS [tex]\neq[/tex] RHS & the  equation is NOT true.
