The pattern here is multiply by 2. Since we can see that the first four numbers are 1, 2, 4, 8, the pattern here is definitely multiply by two. Now, to find the number of tiles he will need in the 7th tile, we will need to raise 2 to the power of something. Since we are multiplying by 2, we are getting different powers of two. The first figure, 1, is two to the power of 0, which means that the power of two for each figure is the figure number minus 1. So, the 7th figure would have 2^{6} tiles which is equal to 64.

The value of (a+b)² - (a-b)² is​
ANEK [815]

Answer:

4ab

Step-by-step explanation:

(a+b)^2-(a-b)^2

=a^2 + 2ab + b^2 -(a^2 - 2ab +b^2)

=a^2 + 2ab + b^2 - a^2 + 2ab - b^2

=2ab + 2ab

A circle has a diameter of 29 feet. What is the area? *
11111nata11111 [884]

Answer:

The answer is

<h2>660.5 square feet</h2>

Step-by-step explanation:

Area of a circle = πr²

where r is the radius

From the question

diameter = 29 feet

To find the radius given the diameter we use the formula

radius =  \frac{diameter}{2}  \\ radius  =  \frac{29}{2}  \\  = 14.5 \:  \: feet

So the area of the circle is

A =  {14.5}^{2} \pi \\  = 210.25\pi \\  = 660.519...

We have the final answer as

<h3>660.5 square feet</h3>

Hope this helps you

Masteriza [31]

Answer:

<h3>              -8(2x +x )/-2y  = - 30</h3>

Step-by-step explanation:

x=-5, y=2 and z=0

-8(2x +x )/-2y =(-8•3x)/-2y = [-8•3(-5)] / (-2•2) = 120/(-4) =-30

Kylie starts with $145 in her piggy bank. Each month she adds $20.
djverab [1.8K]

Kylie's first month collection, a1= $ 145

Second month collection , a2= $145+ 20

Third month collection, a3  = $145 +2*20

.

.

.

.

so for n months collection = an-1+20

We get an= 20 + an-1  and a1=145

How does the graph of y = sec(x + 3) – 7 compare with the graph of y = sec(x)?
Alla [95]

Answer:

The function y = sec(x) shifted 3 units left and 7 units down .

Step-by-step explanation:

Given the function: y = sec(x)

  • If k is any positive real number, then the graph of f(x) - k is  the graph of y = f(x) shifted downward k units.
  • If p is a positive real  number, then the  graph of f(x+p) is  the graph of y=f(x)  shifted to the left  p units.

The function y = \sec(x+3)-7 comes from the base function y= sec(x).  

Since 3 is added added on the inside, this  is a horizontal shift Left 3 unit, and since 7 is subtracted on the outside, this is a vertical shift  down 7 units.

Therefore, the transformation on the given function is shifted  3 units left and 7 units down
