PLEASE HELP!! Identify the minium value of the function

Mathematics

Because this is a positive parabola, it opens upwards, like a cup, and the vertex dictates what the minimum value of the function is.  In order to determine the vertex, I recommend completing the square.  Do that by first setting the function equal to 0 and then moving the 9 to the other side by subtraction.  So far: x^2+6x=-9.  Now, to complete the square, take half the linear term, square it, and add that number to both sides.  Our linear term is 6.  Half of 6 is 3 and 3 squared is 9.  So add 9 to both sides. x^2+6x+9=-9+9.  The right side reduces to 0, and the left side simplifies to the perfect square binomial we created while completing this process.  (x+3)^2=0.  Move the 0 back over and the vertex is clear now.  It is (-3, 0).  Therefore, 0 is the minimum point on your graph.  The first choice above is the one you want.

Parametric equation of the line d: 4x-3y+17=0
zmey [24]

Answer:

x = t/4 and y = (t+17)/3

Step-by-step explanation:

4x-3y+17=0

or, 4x=3y-17

let, 4x = t

so, x = t/4

and 3y-17 = t

or, 3y = t+17

or, y = (t+17)/3

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided.
Maurinko [17]

Answer:

616 square centimeters

Step-by-step explanation:

Area of a circle is equal to pi × r^2. In this case, they have asked that you substitute 3.14 or 22/7 for pi, so I will be using 22/7, instead.

Diameter is equal to 2r; to find the radius, simply divide 28 by two. This gives us a radius of 14.

Multiply 14 squared by 22/7:

(22/7)(14^2)

This gives us (22/7)(196); (4312/7); 616.

Therefore, the area of the circle is approximately 616 square centimeters.
