What is the general form of the equation for the given circle centered at O(0, 0)? The center is (0,0) the point on the circle is (4,5)

Answers

Answer:

x^2+y^2-41=0

Step-by-step explanation:

Center of the circle is (0,0)

the point on the circle is (4,5)

Center radius form of the circle is

(x-h)^2 +(y-k)^2= r^2

where (h,k) is the center and 'r' is the radius of the circle

WE know center is (0,0) . Lets find out the radius using the given point

(x-0)^2 +(y-0)^2= r^2

x^2+y^2= r^2

Plug in the given point (4,5)

4^2+5^2= r^2

16+25= r^2

41=r^2

Equation becomes

x^2+y^2=41

General form of equation is

x^2+y^2+gx+fx+c=0

x^2+y^2=41

x^2+y^2-41=0

Suppose you have 52 feet of fencing to enclose a rectangular dog pen. where x = width, gives you the area of the dog pen in square feet. What width gives you the maximum area? What is the maximum area? Round to the nearest tenth as necessary.

Answers

Answer:

Width which gives maximum area = 13 feet

Maximum Area = 169 feet^2

Step-by-step explanation:

Given: 52 feet of fencing means Perimeter of rectangular dog pen.

If Total length of the boundary of rectangle (.i.e., Perimeter) is fixed then the rectangle with equal sides has the maximum area.

Width = x (given)

∴ for maximum area let length = x

Perimeter of rectangle = 52 feet

2 × (Length + Width) = 52

2 × ( x + x ) = 52

2 × ( 2x ) = 52

4x = 52

x = (52)/(4)

x = 13 feet.

Maximum Area = Length × Width

                          = 13 × 13

                          = 169 feet^2

Width which gives maximum area = 13 feet

Maximum Area = 169 feet^2

Maximum Area = 169 feet^2

Name the property shown. 4 + 0 = 4 1Commutative Property of Multiplication 2.Identity Property of Addition 3.Commutative Property of Addition 4.Associative Property of Addition

Answers

That is Identity Property of Addition.

Identity Property is a property that states that the sum of any number and zero is always the number you added to zero. This is also the case for multiplication by instead of adding zero, you are multiplying by one.

Hope this helps!

It is 2. Identity Property of Addition. The Identity Property of Zero, also called the Additive Identity Property, states that if you add 0 to any number, the result will be that number. ... Think about it: when you add or subtract zero from the number, it retains its identity...it doesn't change! It works for all real numbers (and on variables).
