Answer:

a = -2 and b=4 and c = -4

Step-by-step explanation:

the center is : A(1 ; -2)

B(1 ; 1) in this circle so ; AB= r  (  ridus)...r =3

note :

an equation of the circle Center at the A(1,-2) and ridus : r is :

(x-1)² +(y+2)² = 3²  

x²-2x+1  +y²+4y +4-9 =0

x²+y² -2x+4y -4 = 0   so : a = -2 and b=4 and c = -4

What is the length of the missing leg? If necessary, round to the nearest tenth.
zhannawk [14.2K]

Answer:

5cm

Step-by-step explanation:

To find the missing side we use the hypotenuse theorem.

a^2 + b^2 = c^2

The longest side of the triangle would be c. So substitute the numbers into the variables.

a^2 + 12^2 = 13^2

a^2 = 13^2 - 12^2

a^2 = 169 - 144

a^2= 25

a = √25

a=5

The missing leg's length is 5cm

Mariana [72]

Answer:

The cost of apple juice per ounce is 20 cents.

Explanation:

We know that a

16

ounce bottle is

$

3.20

and we want to find how much per ounce is.

So we set up a proportion and let

x

be the cost of one ounce:

16

3.20

=

1

x

Now we can cross multiply:

16

x

=

3.20

Divide both sides by

16

:

16

x

16

=

3.20

16

Therefore,

x

=

0.20

The cost of apple juice per ounce is 20 cents.

Hope this helps!
