Find the length of the radius for this circle.(x - 3)² + (y - 5)² = 8

8
4
2√2

Answers

Answer: $2√(2)$

Step-by-step explanation:

The general form of equation of a circle is given by :-

$(x-a)^2+(y-b)^2=r^2$ , where r is radius and (a,b) is the center of the circle.

The given equation of circle: $(x - 3)^2 + (y - 5)^2 = 8$

$\Rightarrow\ r^2=8$

Taking square root on both sides, we get

$\Rightarrow\ r=√(8)=2√(2)$

Hence, the length of the radius for this circle= $2√(2)$

we know that the 8 represent the squared radius of the circle so to get the radius we should take the square root of 8
the answer is √8 = 2√2

Find the length of the base of a square pyramid if the volume is 1,024 cubic inches and has a height of 12 inches.

Answers

Hello,

Let 's x the length of the pyramid:
V=x²*h/3
V=1024 and h=12
So x²*12/3=1024
==>x²=1024*3/12
==>x²=256
==>x²=16²
==> x=16 for (x=-16 must be exclude <0)

Which function in vertex form is equivalent to f(x) = 4 + x2 – 2x?

Answers

The question is asking us to find which function in the vertex form is equivalent to f ( x ) = 4 + x^2 - 2 x. We have to add 1 to make a squared binomial ( and also to subtract 1 ). f ( x ) = ( x^2 - 2 x + 1 ) - 1 + 4 = ( x - 1 )^2 + 3. Then we have the vertex point ( 1, 3 ). Answer: The function in vertex form is: f ( x ) = ( x - 1 ) ^2 + 3.

Answer:

Vertex form of the function will be f(x) = (x - 1)² + 3.

Step-by-step explanation:

Vertex form of a quadratic function is given by f(x) = a(x - h)² + k

where (h, k) is the vertex of the given parabola.

Now we will convert the function in the vertex form.

f(x) = x² - 2x + 1 + 3

= (x - 1)² + 3

Therefore, the vertex form of the function will be f(x) = (x - 1)² + 3

and the vertex will be (1, 3).
