Ali graphs the function f(x) = –(x + 2)2 – 1 as shown.
On a coordinate plane, a parabola opens up. It goes through (negative 3, 0), has a vertex at (negative 2, negative 1), and goes through (negative 1, 0). A vertical dashed line at (negative 2, 0) is parallel to the y-axis.
Which best describes the error in the graph?
The axis of symmetry should be x = –1.
The axis of symmetry should be x = 2.
The vertex should be a maximum.
The vertex should be (–2, 1).
Answer:
The axis of symmetry should be x = 2.
Step-by-step explanation:
:)
We have given that the function y = - (x + 2)² - 1. So, The axis of symmetry should be x=2 describing the error in the graph.
What is the vertex form of a quadratic equation?If a quadratic equation is written in the form
[tex]y=a(x-h)^2 + k[/tex]
then it is called to be in vertex form. It is called so because when you plot this equation's graph, you will see vertex point(peak point) is on (h,k)
This point (h,k) is called the vertex of the parabola that the quadratic equation represents.
We have given that the function y = - (x + 2)² - 1
so we have a =-1,
-h=2 implies that h=-2
k=-1
Therefore the vertex is (h,k)=(-2,-1)
vertex = (- 2, - 1)
The axis of symmetry passes through the vertex, is vertical with the equation
x = - 2 is correct.
When the a > 0, the vertex is a minimum
when a < 0, implies that vertex is a maximum
here a=-1 < 0 implies vertex should be a maximum
Since, the vertex(-2,-1) is maximum
Therefore the axis of symmetry should be x=2 to represent error in the graph.

5 Victor knows that 2 + 7 = 7+2 and 2•7= 7•2
Answer:2^7 ≠ 7^2
Step-by-step explanation:
2^7 = 2 * 2 * 2 * 2 * 2 * 2 * 2
The only factor is 2
7^2 = 7 * 7
The only factor is 7
Comparing the factors when written as a repeated multiplication,
2^7 and 7^2 have no common factor :
2^7 = 2 * 2 * 2 * 2 * 2 * 2 * 2 = 128
7^2 = 7 * 7 = 49

Find the area of an equilateral triangle with sides of length 24 inches in simplest
form?
Answer:
B. 144√3 in².
Step-by-step explanation:
Given the following data;
Sides of length = 24 inches
Mathematically, the area of an equilateral triangle is given by the formula;
A = √3 * s²/4
Where, s represents the sides of length.
Substituting into the formula, we have;
A = √3 * 24²/4
A = √3 * 576/4
A = √3 * 144
A = 144√3 in²

A. Russell is 5'9". What is the probability he is a forward?
B. Peter is 6'2". What is the probability he is a guard?
Answer:
0.324
0.068
Step-by-step explanation:
If Russell is 5'9" ; then he is under 6 feets :
Probability = number of forwards under 6 feets / tot number of players
Probability = 120 / 370 = 0.324
Peter is 6'2" ; Peter is over 6 feets ;
Probability that Peter is a guard = (number of guards over 6 feets / total number of players) = 25 / 370 = 0.0676 = 0.068

What is the equation of the trend line in the scatter plot ?
Five friends built a marble tower. The marble tower had a curved track. The track was designed so that the marbles would move down the track in a circular path. The track ended on the floor. Each friend predicted how he or she thought the marble would move when it rolled off the end of the track onto the floor. This is what they said:
Answer:
The best answer is of Keira's.
Step-by-step explanation:
The full question is as follows :
Given - Each friend predicted how he or she thought the marble would move when it rolled off the end of the track onto the floor.
This is what they said:
Magda : '' I think it will roll in circles.''
Soledad : '' I think it will curve for a bit and then straighten out.''
Allen : '' I think it will roll out in one big curve.''
Keira : '' I think it will roll in a straight line,''
Rafael : '' I think it will zigzag for a little while.''
To find - Which friend do you most agree with ?
Proof -
The best answer is Keira's.
The marble having the track will travel in a straight line.
The behavior is true for all objects.
If no outside force act on an object, the object will travel in a straight line at a constant speed.
When the marble leaves the end of the track, it is no longer in contact with the walls of the track.
That is , the marble has no longer a center-pushing force.
According to Newton's First law, an object remains at rest or in uniform motion in a straight line unless acted upon by an external force.
Since, there is no longer a center-pushing force so the marble rolls off the end of the track in a straight line path across the floor.

Answer:
141
Step-by-step explanation:
CD = | 4-(-2)| = 6
DB = |3-(-7)| = 10
area of a right triangle
A = (leg 1 x leg2)/2 = (6 x 10)/2 = 30
EB = |3-(-3)| = 6
EF = |-8-(-2)| = 6
area of a square = side^2
A = 6^2 = 36
segment G(and a point with same x coordinate of H)
|8-3| = 5
segment H(and the same point)
|-10-(-8)| = 2
A = (5x2)/2 = 5
segment I(and the same point)
|-8-6| = 14
Area of a rectangle
A = base x width
A = (5 x 14) = 70
total area = 70 + 5 + 36 + 30 = 141
a circle has a radius of 4.5 inches find the length of the arc outlined by a central angle that measures 0.6pi radians
Answer:
8.478in
Step-by-step explanation:
Length of an arc = rtheta
r is the radius of the circle = 4.5in
theta is the central angle = 0.6pi
Substitute
Length of the arc = 4.5 * 0.6pi
Length of the arc = 4.5 * 0.6 * 3.14
Length of the arc = 8.478inches
Hence the length of the arc is 8.478inches

How many sides does a polygon have if the sum of the interior angles is 2240
?
Answer:
Note: it seems a typo, should be 2340 instead of 2240
Sum of interior angles of a polygon:
S = 180(n - 2)We have:
S = 2340Find n:
180(n - 2) = 2340n - 2 = 2340/180n - 2 = 13n = 1515 sides
90(2n-4)=Sum of interiors
2240=90(2n-4)2240=180n-360180n=2600n=2600/180n=14.4=14
