Complete the square
to find the vertex
of this parabola.
2.
х
- 16 Y-4 x-12=0

Answers

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)

Answers

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.)

Answers

To find these, you will need to find the largest square root inside the radical sign. This is hard for me to explain, but I’ll see what I can do. I will use / as the radical symbol

Rewrite 3:
/45
We know that one pair of factors of 45 is 9 and 5. 9 is a perfect square— 3x3. Therefore, you will write it as 3/5
The number inside the sign cannot be squared in a while number while the number outside is already squared.
So you will rewrite inside the radical sign 9 • 5. To simplify it, you will find the square root of the perfect square. 3 *radical sign* 5

I hope that makes sense, feel free to shoot me a message if you’re confused. I’ll write the rest of the answers down below. Again, I will use / as the radical sign and rewrite 3 to make it easier.

Rewrite 3
/45
= /9•5
= /3•3•5
= 3/5


Rewrite 2
/28
= /4•7
= /2•2•7
= 2/7

Rewrite 1
/20
= /4•5
= /2•2•5
= 2/5

Rewrite 4
/36
= /6•6
= 6

^— This one is different because 36 is already a perfect square. 6•6=36

I had written out the multiplications of the squares because that was the way we were taught. We would cross out the same numbers and then write it outside the radical sign. Hope that helps :)

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?

Answers

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%

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)

Answers

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.

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

Answers

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
