What is the equation of this circle in standard form?

creativ13 [48]

Answer:

Option C.

Step-by-step explanation:

Note : In the given points one point is (8,-2) instead of (-6,-2).

The standard form of a circle is

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

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

It is given that center of the circle is (-1,-2). So,

$h=-1,k=-2$

$(x-(-1))^2+(y-(-2))^2=r^2$

$(x+1)^2+(y+2)^2=r^2$ ...(1)

It is given that the circle passing through the point (8,-2),(-1,5),(6,-2),(-1,-9).

Substitute x=6 and y=-2 in equation (1).

$(6+1)^2+(-2+2)^2=r^2$

$(7)^2+(0)^2=r^2$

$49=r^2$

Substitute $r^2=49$ in equation (1).

$(x+1)^2+(y+2)^2=49$

Therefore, the correct option is C.

Jared earns 0.25 vacation days for every week that he works in a calendar year. He also gets 10 paid company holidays per year.

Rom4ik [11]

1. Jared earns 0.25 vacation days for every week
=> He also gets 10 paids company holidays
Now, write a verbal model and algebraic expression that will represents to get the total amount of holidays will Jared gets.
=>0.25 holidays for every week
=> 0.25 (w) , where w represents the number of weeks I a years
=> 10 paid company holidays
so the expression would be:
=> 0.25w + 10
0.25 will be multiplied by the number of weeks in a year, then added with 10

Answer:

z = 68º

Step-by-step explanation:

40º + 57º = 97º

180º - 97º = 83º

83º + 29º + z = 180º

112º + z = 180º

z = 180º - 112º

z = 68º

Answer:

C. 510 cm^2

Step-by-step explanation:

Well to find TSA or Total Surface Area,

We need to find the area of al the triangles and rectangles.

Let's start with the 2 rectangles facing forwards.

They both have dimensions of 5*15 and 12*15,

75 + 180

= 255 cm ^2

Now let's do the back rectangle which has dimensions of 15 and 13.

15*13 = 195 cm^2

Now we can do the top and bottom triangles,

Since we don't have height we can use the following formula,

$A = \sqrt{S(S-a)(S-b)(S-c)}$

S is $S = \frac{1}{2} (A+B+C)$

S= 15

Now with s we can plug that in,

$A = \sqrt{15(15-5)(15-13)(15-12)}$

The a b and c are the sides of the triangle.

So let's solve,

15 - 5 = 10

15 - 13 = 2

15 - 12 = 3

10*2*3 = 60

60*15 = 900

$\sqrt{900}$ = 30 cm^2

Since there is 2 triangles with the same dimensions their areas combined is 60 cm^2

60 + 255 + 195 = 510 cm^2

Thus,

the TSA of the right triangular prism is C. 510 cm^2.

Hope this helps :)
