Part 2: Use the information provided to write the standard form equation of each circle

Archy [21]

Answer:

The answer to your question is below

Step-by-step explanation:

- The Standard form of the equation is

(x - h)² + (y - k)² = r²

Center (8, -4) r = $\sqrt{118}$

-Substitution

(x - 8)² + (y + 4)² = $\sqrt{118}$ ²

-Result

(x - 8)² + (y + 4)² = 118

Center (-10, 9) r = $\sqrt{37}$

-Substitution

(x + 10)² + (y - 9)² = $\sqrt{37}$ ²

-Result

(x + 10)² + (y - 9)² = 37

6.-

Center (-8, 0) r = 6

-Substitution

(x + 8)² + (y - 0)² = (6)²

-Result

(x + 8)² + (y - 0)² = 36

T.L Hanna High School’s theatre department is putting on their annual play. Tickets (t) are $12 each. Parking is $5 flat. You an

GalinKa [24]

Answer:

No. of ticket bought is 4

Step-by-step explanation:

Let the no. of ticket bought be x

Given cost of 1 ticket = $12

Therefore cost x ticket = x*cost of 1 ticket = x*$12 = $12x

parking fee = $5

given that it is flat so, whatever be the no. of ticket bought or family member,

the parking cost will remain $5 only.

Total money paid by family = parking charge + cost x ticket = 5+12x

But , given that family paid total of $53

then

5 + 12x = 53

=> 12x = 53-5 = 48

=> x = 48/12 = 4

Thus, no. of ticket bought is 4.

This can be validated as shown below

cost of 4 ticket as 12 each will be = 12*4 = 48

thus total money paid = $(48+5 )= $53
