(x – h)^2 + (y – k)^2 = r^2
<span>Where,
(h, k) is the center and </span><span>"r" is the radius.
Substituting the given values:

(x-4)^2 + (y+4)^2 = r^2
</span>
Now using the distance formula. 

<span>r = [(x2-x1)^2 + (y2-y1)^2]^1/2 
</span>
r = [(1 - 4)^2 + (0 + 4)^2]^1/2  
r = [(9+16)]^1/2
r = 25^1/2
r = 5

Substituting the values of r and the center into the main equation:

<span>(x-4)^2 + (y+4)^2 = 25</span>

A square poster has a side length of 26 in. Drawn on the poster are four identical triangles. Each triangle has a base of 8 in.
Firdavs [7]
To find the probability of landing on a triangle, you will want find the combined areas of the triangles and the total area of the square target.

Divide the area of the combined areas and the total area to find the probability of landing on a triangle.

A = 1/2bh
      1/2 x 8 x 8
A = 32 square inches
32 x 4
128 square inches (areas of triangles)

A = bh
     26 x 26
A = 676 square inches

128/676 = 0.189

There is an approximate probability of 0.19 of hitting a triangle.

Rai compares two cable plans from different companies. Which equation gives the correct value of m, the number of months for whi
tekilochka [14]

Answer:

D. 75m = 50(12)+125(m-12)

Step-by-step explanation:

m = months.

Equation for which Plans A and B cost the same.

In Plan A:

No initial fees.

$75 per month

1 month = $ 75

then;

for m month =$75 m

Total cost for plan A =  75m

In Plan B:

$50 per month for first 12 month.

1 month = $50

12 months = 50(12)

Similarly,

$125 per month for each additional month after that.

additional month= (m-12)

Plan B additional month

= 125(m-12)

Total cost for plan B = 50(12)+ 125(m-12)

Since, Plans A and B cost the same.

75m = 50(12)+125(m-12)
