Answer:
Vertex: (–9, 1)
Axis of Symmetry: x = –9
Step-by-step explanation:
x = 9 is the lowest point on the graph. This makes it the x-coordinate of the vertex and the axis of symmetry. Now count how many squares above the x-axis it is. It's 1 square above, right? This means the vertex is (–9, 1).
Hope this helps you. Have a great day!

A, B, C and D and ADC = 120
Find the value of x.
Answers
Answer:
30 degrees
Step-by-step explanation:
The computation of the value of x is given below:
Given that
ADC = 120 degrees
So ABC = 60 degrees
As the sum of the opposite angles are 180 degrees
And ACB = 90 degrees
Now in Triangle ADC
Angle ACB + Angle ABC + x = 180 degrees
90 + 60 + x = 180
x = 30 degrees

What is the x- value of the midpoint between A (-8,-6) and B (0, 6)?
Answers
Answer:
Step-by-step explanation:
Take average of the x-coordinates of A and B.
(-8+0)/2 = -4
x-coordinate of midpoint = -4
The required x value of the midpoint between A(-8, -6) and B (0, 6) is -4.
Given that,
To determine the x value for the midpoint between A (-8,-6) and B (0, 6).
Coordinate, is represented as the values on the x-axis and y-axis of the graph. Where x coordinate of the graph is called an abscissa and y coordinate of the graph is called ordinate.
The midpoint is that point of the line which has an equal distance from both ends of the line.
the x value of the midpoint between A(-8, -6) and B (0, 6) is given by,
x = ( x1 + x 2) / 2
x = ( - 8 + 0 ) / 2
x = - 8 / 2
x = - 4
Thus, the required x value of the midpoint between A(-8, -6) and B (0, 6) is - 4.

We know that 70% of 100 is 70 but since we are working with 10 we can use a proportion.
However, just by looking at the numbers we can conclude it is 70% because if you take a zero off of 100 and 70 it is still proportionally equal to 100 and 70. Therefore, the answer is 70%.

r² = 204
r = 14.28 ft
Now
Circumference

Huy is solving a quadratic equation by completing the square. His first few steps (steps 1-4) are shown below. Which of the following statements is true regarding Huy's work?
Given x2+3x−5=0
Solution x2+3x=5 step 1
x2+3x+9=5+9 step 2
(x+3)2=14 step 3
x=−3±14−−√ step 4(1 point)
Huy is incorrect. He made a mistake in step 1 when he added a 5 to both sides. He should have only added a 5 to the left side of the equation.
Huy is incorrect. He made a mistake in step 4 when he solved the equation (x+3)2=14 for x.
Huy is incorrect. He made a mistake in step 2 of the solution when he added a 9 to both sides.
Huy is correct. He has done a nice job of completing the square.

The true statement will be;

What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The quadratic equation is,
⇒ x² + 3x - 5 = 0
Now,
Huy is solving a quadratic equation by completing the square.
The steps are;
The quadratic equation is,
⇒ x² + 3x - 5 = 0
Solution; x²+3x=5 (step 1)
x²+3x+9 = 5+9 (step 2)
(x + 3)² = 14 (step 3)
x = - 3 ± √14 (step 4)
Clearly, In step 2 when add 9 then it not make the square form.
That is,
x² + 3x + 9 ≠ (x + 3)²
Thus, The true statement will be;
''Huy is incorrect. He made a mistake in step 2 of the solution when he added a 9 to both sides.''

One interior angle of a convex polygon (a convex polygon is a polygon where all angles
are less than 180 degrees) is 120 degrees. All the other angles are 130 degrees. How many sides
does the polygon have?
Answers
Answer:
7 sides
Step-by-step explanation:
120 + 130x = 180 * (x+1-2)
120 + 130x = 180x - 180
300 = 50x
x = 6
You get that x = 6, but there is still one angle that equals 120, so you have a 7 sided polygon.

According to an AP-Ipsos poll (June 15, 2005), 42% of 1001 randomly selected adult Americans made plans in May 2005 based on a weather report that turned out to be wrong.
a. Construct and interpret a 99% confidence interval for the proportion of Americans who made plans in May 2005 based on an incorrect weather report.
b. Do you think it is reasonable to generalize this estimate to other months of the year
Answers
Answer:
a) The 99% confidence interval for the proportion of Americans who made plans in May 2005 based on an incorrect weather report is (0.3798,0.4602). This means that we are 99% sure that the true population proportion is in this interval.
b) No, since May is a month with a wide range of possible weather.
Step-by-step explanation:
a)
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
42% of 1001 randomly selected adult Americans made plans in May 2005 based on a weather report that turned out to be wrong.
This means that [tex]p = 0.42, n = 1001[/tex]
99% confidence level
So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.42 - 2.575\sqrt{\frac{0.42*0.58}{1001}} = 0.3798[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.42 + 2.575\sqrt{\frac{0.42*0.58}{1001}} = 0.4602[/tex]
The 99% confidence interval for the proportion of Americans who made plans in May 2005 based on an incorrect weather report is (0.3798,0.4602). This means that we are 99% sure that the true population proportion is in this interval.
b. Do you think it is reasonable to generalize this estimate to other months of the year
No, since May is a month with a vast number of possible outcomes, as it is in the spring, not being in the winter(cold) or summer(hot), which means that it can be both hot or cold, wet or dry,...
