<span> we have that
standard form of equation for parabola:
 (x-h)^2=-4p(y-k)
(h,k) --------->being the (x,y) coordinates of the vertex.
Parabola opens downwards because focus is below vertex on the axis of symmetry.
For given problem:
</span><span>vertex: (-3,2)
axis of symmetry: x=-3
p=distance from vertex to focus on the axis of symmetry=2-(-1)=3
4p=12
Directrix: y=2+p=5
Equation:
(x+3)^2=-12(y-2)

the answer is </span>(x+3)^2=-12(y-2)

Complete question

<em>18. GOLF Luis and three friends went golfing. Two of the friends rented clubs for $6 each. The total cost of the rented </em>

<em>clubs and the green fees for each person was $76. What was the cost of the green fees for each person? Define a </em>

<em>variable, write an equation, and solve the problem.</em>

The variable defined is "y", the equation is 4y + 2(6) = 76 and the value of the unknown variable is 16

Let the cost of green fees per person be y

If Luis and three friends went golfing, this means that 4 people went golfing.  The total cost of green fees for all of them will be $4y

If two of the friends rented clubs for $6 each, total amount spent will be $2(6)

The equation that models the statement will then be expressed as;

4y + 2(6) = 76\\

Solve for y

4y + 2(6) = 76\\4y+12 = 76\\4y = 76 - 12\\4y = 64\\y =\frac{64}{4}\\y = 16

The variable defined is "y", the equation is 4y + 2(6) = 76 and the value of the unknown variable is 16.

Diano4ka-milaya [45]

Answer:

30 centimeters^2

Step-by-step explanation:

The area of a triangle can be found using the following formula.

A= (b*h)/2

In this triangle, the base is 12 cm. The height is 5 cm, since it forms a right angle with the base.

b= 12 cm

h= 5 cm

A= (12 cm * 5 cm) / 2

Solve inside the parentheses first. Multiply 12 cm and 5 cm.

A= (60 cm^2) / 2

Divide 60 cm^2 by 2

A= 30 cm ^2

The area of the triangle is 30 square centimeters.
