Complete the square
to find the vertex
of this parabola.
2.
х
- 16 Y-4 x-12=0
Answer:
Vertex coordinates; (h,k) = (2, -1)
Step-by-step explanation:
Vertex form of a parabola is;
y = a(x - h)² + k
Now, we are given;
x² - 16y - 4x - 12 = 0
Rearranging, we have;
x² - 4x = 16y + 12
Let's complete the square on the left hand side;
First add square of half of the coefficient of x to both sides;
x² - 4x + (-½ × 4)² = 16y + 12 + (-½ × 4)²
x² - 4x + 4 = 16y + 12 + 4
LHS can be expressed as;
(x - 2)² = 16y + 16
16y = (x - 2)² - 16
Divide both sides by 16 to get;
y = (1/16)(x - 2)² - 1
Comparing this with y = a(x - h)² + k, we have;
a = 1/16
h = 2
k = -1
(h,k) = (2, -1)
Consider the data set.

Which statement describes a way to find the median of the data set?
Answer:
Median: 9
1 3 6 6 9 10 11 12 31
Step-by-step explanation:
To find the median, you have to organize your terms from least to greatest. And then find the center of your terms, which would be 9.

Answer:
A is false (Y is far left of 0, so it is a negative. H is close to 0 so it is positive. Y is farther from zero, so it is bigger. For example, Y could be -7, and H could be 3. The sum of -7 and 3, would be -5.
B is false (E is on the left of 0 so it is negative. Y is on the left of zero so it is also negative. Negative divided by a negative is a positive )
C is false (H is positive and E is negative. Positive times a negative equals a negative.)
D is true (A is close to zero, so it is a small positive number. H is farther from zero, so it is a larger positive number. For example, A can be 2 and H can be 5. So, 3 - 5 would equal a negative.)

The rectangular pyramid below has a volume of 200 m3. What is the height of the rectangular pyramid in meters? If the base is 6 by 5 meters
Answer:
6.67meters
Step-by-step explanation:
The formula for the volume of a rectangular pyramid = Length × Width × Height
From the question
Volume = 200m³
Base of the pyramid = Length × Width = 6m by 5m = 6m × 5m
To find the height of the pyramid = Volume/Length × Width
Height = 200m³/ 6m × 5m
Height = 6.67m
Height of the rectangular pyramid in meters = 6.67 m

One member from a book club is randomly selected. There is a 40% chance the member is male, and there is a 15% chance that the member is male and finished reading the last book. What is the probability that the member did not finish reading the last book, given that the member is male?
Answer:
18%
Step-by-step explanation:
Given that
40% would be the chances the member is male
And, 15% chance that the member is male and finished the reading of the last book
We need to find out the probability
Let us assume the probability of reading the last book be P(R)
The probability that the member is a male, P(M) = 0.4
The probability that the member is male and finished reading the last book, P(M ∩ R) = 0.15
Now
P(M ∩ not R) = 0.40 - 0.15
= 0.25
P(not R | M) = P(M ∩ not R) ÷ P(M)
P(not R | M) = 0.18
= 18%
Find the size of the angle 3x.
3x=
Answer:
60 degrees
Step-by-step explanation:
a straight line is 180 degrees
2x= 120 degrees
x=60 degrees
Answer:
The value of x is 60°
Step-by-step explanation:
For a given Straight Line
We know that, The straight angle is an angle equal to 180°
So,
3x = 180
Divide by 3 from both side
3x/3 = 180/3
x = 60°
Thus, The value of x is 60°

roman numbers*
XCIX = LV _ XXXIII
XI
i need to know what signs go where is it "+ +" or "- +"
or "+ -" or "- +" ???
Answer:
The sign that go in the expression is - "+ +"
Step-by-step explanation:
Given - XCIX = LV _ XXXIII _ XI
To find - i need to know what signs go where is it "+ +" or "- +" or "+ -" or "- +" ???
Proof -
We know that from the table that,
XCIX = 99
LV = 55
XXXIII = 33
XI = 11
So,
The equation becomes
99 = 55 _ 33 _ 11
Now,
If we put + + then the equation becomes
99 = 55 + 33 + 11
⇒99 = 99
It satisfies.
Now,
If we put - + then the equation becomes
99 = 55 - 33 + 11
⇒99 = 33
It does not satisfies.
Now,
If we put + - then the equation becomes
99 = 55 + 33 - 11
⇒99 = 77
It does not satisfies.
So,
The sign that go in the expression is - "+ +"
The correct mathematical signs are "++" to have XCIX = LV + XXXIII + XI
This is the application of Roman Numerals.
Given the expression XCIX = LV _ XXXIII _XI
We need to know which of the signs will fit in the space provided in the equation.
First, we need to convert the roman numeral to roman figures as shown:
XCIX = 99
LV = 55
XXXIII = 33
XI = 11
Taking the sum of the right-hand side of the equation;
55 + 33 + 11 = 99
This shows that the correct mathematical signs are "++" to have
XCIX = LV + XXXIII + XI

2. The length of a rectangle is 18 centimeters and the width is 6 centimeters. A similar rectangle
has a width of 2 centimeters. What is the length of the second rectangle? (Sketch a picture)
Answer:
6
Step-by-step explanation:
I am unable to sketch a picture for you but I will do my best to help you understand. We know that our length of the first rectangle is 18 cm and the width is 6 cm. At the moment we don't need 18 so we'll put that to the side for now and focus on the width. We understand that in a second similar rectangle, the width is 2 centimeters. in order to find our scale, we must divide the larger width by the smaller width. This means we will divide 6cm by 2 cm. 6/2=3 This means that we also divide 18 by 3 since the similar rectangle is smaller and we are figuring out the missing side. After dividing 18 by 3 we should get an answer of 6. 18/3=6 Which means that our similar rectangle has a length of 6 cm and a width of 2 cm.
I also want to mention that similar rectangles are not the same rectangle however you can think of them as enlargerd/shrunk versions of the original rectangle. I hope this helps.
