A sequence of patterns is made from circular tiles and square tiles. Here are the first three patterns in the sequence:


a) How many square tiles are needed to make Pattern Number 7? [2 MARKS]

b) How many circular tiles are needed to make Pattern Number 20? [2 MARKS]

c) When the pattern number is odd, the total number of tiles (SQUARE & CIRCULAR) needed to make the pattern: A - will always be even | B - will always be odd | C - could be even or odd | [2 MARKS]


!! PLEASE ANSWER ALL OF THE QUESTIONS !!

Answers

Answer:

  a) 49

  b) 84

  c) (B) -- always odd

Step-by-step explanation:

We observe that the number of square tiles is the square of the pattern number. The number of circular tiles is 1 more than the pattern number on each side of the square.

  square tiles = n²

  circular tiles = 4(n +1)

__

a)

7² = 49 square tiles are needed for pattern number 7.

__

b)

4(20+1) = 84 circular tiles are needed for pattern number 20.

__

c)

The parity of the number of square tiles matches the parity of the pattern number. (The square of a number has the same parity as the number.) Since 4 is a factor in the number of circular tiles, its parity is always even. The parity of the total number of tiles will match the parity of the pattern number.

When the pattern number is odd, the total number of tiles will always be odd. (B)

Is (2,1) a solution to this system of equations??
8x+7y=11
x+y=3

a) Yes
b) No​

Answers

Answer:

No

Step-by-step explanation:

In the ordered pair (2,1), 2 is the x-value and 1 is the y-value.

In the first equation, replace x with 2 and y with 1.

8x+7y

= 11

8(2)+7(1)

≟ 11

16+7

≟ 11

23

≟ 11

No, 23≠11.

Plugging (2,1) into the first equation did not result in a true statement. So, (2,1) is not a solution to the system of equations.

It’s y = (x + 1) ^2 - 9

Answer:

Option 2: y = a(x + 1)² - 9

Step-by-step explanation:

Given the graph of an upward-facing parabola, whose vertex occurs at point (-1, -9) as its minimum point.  

Vertex Form

Using the vertex form of the quadratic equation, y = a(x - h)² + k:

where:

a = determines the wideness and the direction of where the graph opens.

(h, k) = vertex

h = determines the horizontal translation of the graph

k = determines the vertical translation of the graph

Using the vertex, (-1, -9), and another point from the graph, (2, 0), substitute these values into the vertex form to solve for the value of a:

y = a(x - h)² + k

0 = a[2 - (-1)]² - 9

0 = a(2 + 1)² - 9

0 = a(9) - 9

Add 9 to both sides to isolate a:

0 + 9 = 9a - 9 + 9

9 = 9a

Divide both sides by 9 to isolate a:

[tex]\displaystyle\mathsf{\frac{9}{9}\:=\:\frac{9a}{9}}[/tex]

a = 1

Final answer:

Therefore, the vertex form of the given parabola is: y = a(x + 1)² - 9.

What do you know about these two lines?

y = 6x - 1
y = -6x - 4

A: The lines are parallel because their slopes are the same.
B: The lines are perpendicular because the slopes are opposites reciprocals
C: The lines are neither parallel nor perpendicular, they just intersect.

Answers

Answer: Choice C

Explanation:

Refer to the y = mx+b form

m = slopeb = y intercept

The slopes are the only thing we focus on. For the equations y = 6x-1 and y = -6x-4, the slopes are 6 and -6 in that order.

The slopes are not equal, so the lines aren't parallel.

The slopes aren't opposite reciprocals of one another, so they aren't perpendicular either. An example of an opposite reciprocal pairing would be 6 and -1/6. Any pair of nonzero opposite reciprocal slopes always multiply to -1.

Therefore, the two lines are neither parallel nor perpendicular, they just intersect.

Answer:

Step-by-step explanation:

Formula: [tex]A = P(1 + \frac{r}{n})^{nt}[/tex]

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

[tex]r = \frac{r}{100}[/tex]

[tex]r = \frac{1.4}{100}[/tex]
