Which equation represents a parabola that opens upward, has a minimum at x = 3, and has a line of symmetry at x = 3?
densk [106]

Answer:

A.\ y = x^2 - 6x + 13 is the correct answer.

Step-by-step explanation:

We know that vertex equation of a parabola is given as:

y = a(x-h)^2+k

where (h,k) is the vertex of the parabola and

(x,y) are the coordinate of points on parabola.

As per the question statement:

The parabola opens upwards that means coefficient of x^{2} is positive.

Let a = +1

Minimum of parabola is at x = 3.

The vertex is at the minimum point of a parabola that opens upwards.

\therefore h = 3

Putting value of a and h in the equation:

y = 1(x-3)^2+k\\\Rightarrow y = (x-3)^2+k\\\Rightarrow y = x^2-6x+9+k

Formula used: (a-b)^2=a^{2} +b^{2} -2\times a \times b

Comparing the equation formulated above with the options given we can observe that the equation formulated above is most similar to option A.

Comparing y = x^2 - 6x + 13 and y = x^2-6x+9+k

13 = 9+k

k = 4

Please refer to the graph attached.

Hence, correct option is A.\ y = x^2 - 6x + 13

Need help with number 2 please help. Due today!!​
Blababa [14]

Answer:

Radius = 9

Step-by-step explanation:

Circumference = 2πr

2πr = 18 ×3.14

2πr = 56.5

6.28r = 56.5

r = 56.5/6.28

r = 9.04 round off , 9

BRAINLIESTTT ASAP! PLEASE HELP ME :)
marta [7]

We can use the Pythagorean theorem to solve for the perimeter of the kite.

a² + b² = c²

3² + 4² = UV²

9 + 16 = UV²

25 = UV²

√25 = √UV²

5 = UV

In the kite, adjacent sides are the same so UV = VW

3² + 9² = UX²

9 + 81 = UX²

90 = UX²

√90 = √UX²

9.49 ≈ UX or 3√10 ≈ UX

Now, add to find the perimeter.

5 + 5 + 9.49 + 9.49 or 5 + 5 + 3√10 + 3√10

28.98 or 10 + 6√10

Therefore, the perimeter is approximately 28.98 or 10 + 6√10

Best of Luck!
