Answer:

1/6

Step-by-step explanation:

The x-coordinate of the vertex is always the x-value of the axis of symmetry. The vertex can be found by x=\frac{-b}{2a}. If we look at this equation as y=ax^{2} +bx+c,

b=1 and a=-3.

When you plug those values into the x equation you get x=\frac{1}{6}.

THIS IS THE LAST QUESTION IDK HOW DO SOLVE IT :(
harkovskaia [24]

Answer:

6 laps.

Step-by-step explanation:

On Monday she runs 2x + 8 miles, where x miles = the length of the trail.

On Tuesday she runs 4x + 4 miles and this is the same distance as Monday, so

2x + 8 = 4x + 4

4 = 2x

x = 2  miles which is the length of the trail.

So each day she runs 4(2) + 4 = 12 miles.

So on Saturday she runs  12/ 2 = 6 laps.

Lucy is designing a new board game, and is trying to figure out all the possible outcomes. How many different possible outcomes
Nadusha1986 [10]

The total possible outcomes are there if she rolls a fair die in the shape of a pyramid that has four sides labeled 1 to 4, spins a spinner with 5 equal-sized sections is 20.

<h3>What is permutation and combination?</h3>

A permutation can be defined as the number of ways a set can be arranged, order matters but in combination the order does not matter.

We have:

Total number of outcomes for pyramid = 4

Total number of outcomes for spinner = 5

Total outcomes = 4×5  (multiplication rule of counting)

= 20

Thus, the total possible outcomes are there if she rolls a fair die in the shape of a pyramid that has four sides labeled 1 to 4, spins a spinner with 5 equal-sized sections is 20.
