What is an equation of circle O shown in the graph below?

vovangra [49]

Answer:

Equation of circle is $x^2+y^2-12x-4y+24=0$

None of the options is correct

Step-by-step explanation:

Given: Graph

To find: equation of circle

Solution:

A circle is a locus of all points that are at a fixed distance (radius) from a fixed point (centre).

From the graph,

centre (a, b) = $\left ( 6,2 \right )$

radius (r) = 4 units

Equation of circle is of form $(x-a)^2+(y-b)^2=r^2$

$(x-6)^2+(y-2)^2=4^2\\x^2+36-12x+y^2+4-4y=16\\x^2+y^2-12x-4y+24=0$

What percentage of the actual salary are the actual total expenses?

Setler79 [48]

Answer:

95.97%

Step-by-step explanation:

Observing the table we have

The actual salary is $3,600 -----> This amount represent the 100%

The actual total expenses are $3,455

using proportion

Find out what percentage of the actual salary are the actual total expenses

$\frac{100}{3,600}=\frac{x}{3,455}\\ \\ x=100*3,455/3,600\\ \\ x=95.97\%$

Need help and will be giving Brainliest

Katena32 [7]

Answer:

x-intercept (s):

For this case h (x) = 0

x2 - 2x - 8 = 0

(x-4) * (x + 2) = 0

x1 = 4

x2 = -2

y-intercept:

For this case x = 0

h (0) = (0)2 - 2 (0) - 8

h (0) = - 8

vertex:

We derive the equation:

h '(x) = x2 - 2x - 8

h (x) = 2x - 2

We match zero:

2x-2 = 0

x = 2/2

x = 1

We evaluate the function for x = 1

h (1) = (1)2 - 2 (1) - 8

h (1) = 1 - 2 - 8

h (1) = -9

The vertex is:

(1, -9)

axis of symmetry of the function:

x = 1

Step-by-step explanation:
