Answer:

C) Regular Octagon.

Step-by-step explanation:

First let's see what a tessellation is.

Tessellation is a floor made by regular types of tiles without overlapping and gap.

We cannot use all shape of tiles to tessellate a plane.

We are given Regular pentagon, irregular triangle and regular octagon.

The pentagon has 5 sides, all sides are in the same length. We cannot tessellate a plane using pentagon.

The second figure is a irregular triangle, we cannot make tessellate a plane using irregular shapes.

The third figure is a regular octagon. We can tessellate a plane using a regular octagon.

Therefore, answer is C) Regular Octagon.

Write an equation in slope intercept form for the line that goes through the point (-2,-5) and (3,5)
Orlov [11]

Answer:

Slope intercept form is y=mx+b

Let’s first find the slope, which is y2-y1/x2-x1

Let’s make the point (-2,-5) our x1 and y1 and let’s make the point (3,5) our x2 and y2.

5+5/3+2

10/5

2 = slope

So far, our equation is looking like this:

y=2x + b

To find the y-intercept (b), let’s plug in one of the points.

Let’s use the point (3,5)

(5)=2(3) + b

5=6 + b

What adds to 6 to equal 5? -1

So, our y-intercept is going to be -1

Finally, our equation is going to look like this:

y=2x-1

The number of decimal places in the product will be sum of the factor"s decimal place.So the product will have 1,2,3 or 4 decima
vampirchik [111]

Answer:

0.47 \to 2\ digits

3.2 \to 1\ digit

Product \to 3\ digits

Step-by-step explanation:

Given

0.47 * 3.2 =

See comment for complete question

Required

The number of decimal places

To do this, we simply calculate the number of digits after the decimal points

0.47 \to 2\ digits

3.2 \to 1\ digit

The product is the sum of the digits above 2 + 1 = 3

Hence:

Product \to 3\ digits

The position of an object moving along an x axis is given by x = 3.24 t - 4.20 t2 + 1.07 t3, where x is in meters and t in secon
Pavel [41]

Answer and explanation:

Given : The position of an object moving along an x axis is given by x=3.24t-4.20t^2+1.07t^3 where x is in meters and t in seconds.

To find : The position of the object at the following values of t :

a) At t= 1 s

x(t)=3.24t-4.20t^2+1.07t^3

x(1)=3.24(1)-4.20(1)^2+1.07(1)^3

x(1)=3.24-4.20+1.07

x(1)=0.11

b) At t= 2 s

x(t)=3.24t-4.20t^2+1.07t^3

x(2)=3.24(2)-4.20(2)^2+1.07(2)^3

x(2)=6.48-16.8+8.56

x(2)=-1.76

c) At t= 3 s

x(t)=3.24t-4.20t^2+1.07t^3

x(3)=3.24(3)-4.20(3)^2+1.07(3)^3

x(3)=9.72-37.8+28.89

x(3)=0.81

d) At t= 4 s

x(t)=3.24t-4.20t^2+1.07t^3

x(4)=3.24(4)-4.20(4)^2+1.07(4)^3

x(4)=12.96-67.2+68.48

x(4)=14.24

(e) What is the object's displacement between t = 0 and t = 4 s?

At t=0, x(0)=0

At t=4, x(4)=14.24

The displacement is given by,

\triangle x=x(4)-x(0)

\triangle x=14.24-0

\triangle x=14.24

(f) What is its average velocity from t = 2 s to t = 4 s?

At t=2, x(2)=-1.76

At t=4, x(4)=14.24

The average velocity  is given by,

\triangle x=x(4)-x(2)

\triangle x=14.24-(-1.76)

\triangle x=14.24+1.76

\triangle x=16
