Determine the equation of the graph, and select the correct answer below.
Alinara [238K]

Answer:

The equation of the parabolic function is :

y=(x-1)^2-3

Step-by-step explanation:

The standard equation of a parabola is given by:

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

where (h,k) represents the vertex of the parabola.

From the graph shown in figure we can find the vertex of the parabola which is the minimum point of parabola and lies st point (1,-3)

So, we can say:

(h,k)\rightarrow (1,-3)

Plugging in the values of vertex in standard equation of parabola,

y=a(x-1)^2+(-3)

Simplifying the equation:

y=a(x-1)^2-3

We can find value of a by plugging in a point from the graph.

Using point (0,-2) which lies on graph.

Plugging in the given point.

-2=a(0-1)^2-3

-2=a-3

Adding 3 to both sides.

-2+3=a-3+3

1=a

∴ a=1

Plugging in a=1, the equation of parabola can be written as:

y=(x-1)^2-3

Jeanette sells hand-painted signs. She earns a $425 weekly salary in addition to $30 for each sign she sells. Write a linear equ
andrew11 [14]

Answer:

=425+30x

Step-by-step explanation:

Given:

Fixed salary earned by Jeanette per week = \$425

Additional amount earned by her for each sign she sells = \$30

To find: linear equation which represents her weekly pay based on the number of signs she sells.

Solution:

Let number of signs sold by Jeanette be x

So, her weekly pay = fixed pay + Additional amount earned by her for each sign she sells

=425+30x

In rhombus FGHJ, m∠1=37°.<br><br> What is m∠2?
777dan777 [17]

Answer:

m∠2 = 53°

Step-by-step explanation:

We will use two properties of a rhombus to solve this problem.

1). Opposite angles of a rhombus are equal.

2). Diagonals bisect the angles.

Since ∠JFG and ∠JHG are the opposite angles of the rhombus,

m∠JFG = m∠JHG

Since, diagonal FH bisect ∠JHG,

m∠FHJ = m∠GHF = m∠JFH = m∠GFH = 37°

In triangle JFH,

m∠FHJ + m∠JFH + m∠HJF = 180°

37° + 37° + m∠HJF = 180°

m∠HJF = 180 - 74

            = 106°

Since, diagonal GJ bisects angle HJF,

m∠FJG = \frac{106}{2} = 53°

Therefore, m∠2 = 53°.

What does it mean when the average is less than the median?
lawyer [7]
<span>This is common for a distribution that is skewed to the right (that is, bunched up toward the left and with a "tail" stretching toward the right). Similarly, a distribution that is skewed to the left (bunched up toward the right with a "tail" stretching toward the left) typically has a mean smaller than its median.</span>
