Answer:

Step-by-step explanation:

So this is a quadratic sequence.

3, 12, 22, 33, 45, 58, 72

9 10 11 12 13 14

9, 10, 11, 12, 13, 14

1 1 1 1 1

This means the next one must be 15 so

3, 12, 22, 33, 45, 58, 72, x

9 10 11 12 13 14 15

x= 72+15

x= 87

What does the graph of f(x)=3x^2-2x+1 look like

aleksklad [387]

Answer:

Below.

Step-by-step explanation:

This is a parabola.

As the coefficient of x^2 is positive it will open upwards ( shaped like a 'U').

If we convert to vertex form we can find the line of symmetry and the coordinates of the vertex:

f(x) = 3x^2 - 2x + 1

f(x) = 3(x^2 - 2/3 x) + 1

f(x) = 3[(x - 1/3)^2 - (1/3)^2] + 1

f(x) = 3(x - 1/3)^2 - 1/3 + 1

f(x) = 3(x - 1/3)^2 + 2/3

So the line of symmetry is x = 1/3 and

the vertex ( the minimum of the curve) is at (1/3, 2/3).

HELP ME PLEASE! 30 POINTS

bazaltina [42]

Answer:

C=14

Step-by-step explanation:

To find the minimum value, graph each of the inequalities. After graphing each inequality, test a point and shade the region that satisfies the inequality. Once all inequalities have been shaded, find the region where they all overlap. The region will be bounded by intersection points. Test each of these points into C=x+3y. The least value for C is the minimum.

(14,0) (0,17.5) (3.08,3.64)

C=14+3(0) C=0+3(17.5) C=3.08 + 3(3.64)

C=14 C=52.5 C=14
