Answer:

a1 = -7

a2 = - 13

a3 = - 19

Step-by-step explanation:

n = 1

a1 = 2*(-3)*1`- 1

a1 = -6 - 1

a1 = - 7

n=2

a2 = 2(-3)*2 - 1

a2 = -12 -1

a2 = - 13

n3 = 2(-3)*3 - 1

n3 = -18 - 1

n3 = -19

Each term is - 6 away from the previous one.

Find either the maximum or the minimum value of the following quadratic equation. Be sure to show all of your work and identify
podryga [215]

Answer:

the minimum is (1,-9)

Step-by-step explanation:

y = 5x^2 - 10x - 4

since the parabola opens upward  5>0, this will have a minimum

it will occur along the axis of symmetry h=-b/2a

y =ax^2 +bx+c

h = -(-10)/2*5

h  = 10/10 =1

the minimum occurs at x =1

the y value for the minimum is calculated by substituting x =1 back into the equation

y = 5 * 1^2 - 10*1 -4

y = 5*1^2 -10 -4

y = 5-10-4

y = -9

the minimum is (1,-9)

Which function has a vertex at the origin?
dlinn [17]

Answer:

  (d)  f(x) = -x²

Step-by-step explanation:

For the vertex of the quadratic function to be at the origin, both the x-term and the constant must be zero. That is, the function must be of the form ...

  f(x) = a(x -h)² +k . . . . . . . . . . vertex form; vertex at (h, k)

  f(x) = a(x -0)² +0 = ax² . . . . . vertex at the origin, (h, k) = (0, 0)

Of the offered answer choices, the only one with a vertex at the origin is ...

  f(x) = -x² . . . . . a=-1

Answer:

Rachel earn $85 in 10 hours.

Step-by-step explanation:

Rachel earned $34 in 4 hours at her job today. It means we can find his earning in 1 hour.

1 hour = $(34/4)
