Given the functions f(x) = 3x2, g(x) = x2 − 4x + 5, and h(x) = –2x2 + 4x + 1, rank them from least to greatest based on their axis of symmetry.

Answers

f(x) = 3x^2 : axis of symmetry is x = 0.
g(x) = x^2 - 4x + 5 = (x - 2)^2 + 1 : axis of symmetry is x = 2
h(x) = -2x^2 + 4x + 1 = -2(x - 1)^2 + 3 : axis of symmetry is x = 1

Therefore, based on their axis of symmetry, f(x) < h(x) < g(x)

Seth has 4 plaid shirts and 5 solid-colored shirts hanging together in a closet. In his haste to get ready for work. He randomly grabs 1 of these 9 shirts. What is theprobability that the shirt Seth grabs is plaid? I have terible problems with ration, please i need help :(

Answers

The probability that the shirt Seth grabs is plaid will be 4/9.

What is Probability?

The term probability refers to the likelihood of an event occurring.

Given that;

Number of plaid shirts = 4

Number of solid colored shirt = 5

Now, Total number of shirts = 4 + 5

                                           = 9 shirts.

Since, Of these 9 shirts, 4 shirts are plaid.

Thus, The probability that the shirt Seth grabs is plaid,

= Number of plaid shirts / Number of total shirts

= 4 / 9

Thus, The probability that the shirt Seth grabs is plaid will be 4/9.

Find the equation of the horizontal line that passes through the point: (-1, 5

Answers

Because the line is horizontal, the y value would be the same across it, which means that the y intercept is 5. You would then write the final answer as y = 5. I hope this helps!
