Use the Graph of the parabola to fill in the table

Andre45 [30]

Answer:

a) Upwards

b) x = -1

c) (-1,-9)

d) x intercepts; (2,0) and (-4,0)

y intercept is (0,-8)

Step-by-step explanation:

a) As we can see, the parabola faces upwards

b) To find the axis of symmetry equation, we look at the plot of the graph and see the point through the vertex of the parabola that exactly divides the parabola into two equal parts

The x-value that the line passes through here is the point x = -1 and that is the equation of the axis of symmetry

c) The vertex represents the lowest point of the circle here,

As we can see, this is the point through which the axis of symmetry passes through to make a symmetrical division of the parabola

We have the coordinates of this point as

(-1,-9)

d) The intercepts

The x-intercept are the two points in which the parabola crosses the x-axis

We have this point as 2 and -4

The x-intercepts are at the points (2,0) and (-4,0)

For the y-intercept; it is the y-coordinate of the point at which the parabola crosses the y-axis and this is the point (0,-8)

Question 7 A number cube with faces labeled from 1 to 6 will be rolled once. The number rolled will be recorded as the outcome.

QveST [7]

Answer:

1) $S=\{1,2,3,4,5,6\}$

2) $O=\{1,3,5\}$

Step-by-step explanation:

Given : A number cube with faces labeled from 1 to 6 will be rolled once. The number rolled will be recorded as the outcome.

To find : Give the sample space describing all possible outcomes. Then give all of the outcomes for the event of rolling an odd number. If there is more than one element in the set, separate them with commas ?

Solution :

A number cube with faces labeled from 1 to 6 will be rolled once.

The sample space describing all possible outcomes is given by

$S=\{1,2,3,4,5,6\}$

All of the outcomes for the event of rolling an odd number is given by

$O=\{1,3,5\}$

Which three side lengths best describe the triangle in the diagram?

Ksenya-84 [330]

The three side length that describes the triangle in the image attached below are: 5 cm, 12 cm, and 13 cm.

<h3>What is a Triangle?</h3>

A triangle is a shape that has three sides. The sides can be measured using a ruler.

The sides of the triangle in the image shown have side lengths as measured by the ruler beside each of the sides, which are 5 cm, 12 cm, and 13 cm.

Therefore, the three side lengths of the triangle in the diagram are: 5 cm, 12 cm, and 13 cm.
