1 answer:

8 0

Turn them all into decimals so you can clearly see the difference between them

8 1/9 = 8.11
8.117
8.28
163/20 = 8.15

8 1/9, 8.117, 163/20, 8.28 is your answer

The acceleration y, in meters per second squared, of an object after x seconds is given by y = 7 sin (pi/4 x). During the first

Nataly_w [17]

Answer: (0, 2) and (6, 10)

Step-by-step explanation:

The acceleration is:

y = 7*sin( x*pi/4).

Over which interval is the acceleration increasing?

First, let's study the sin function:

Sin(θ) increases between -pi/2 and pi/2

Sin(θ) decreases between pi/2 and (3/2)*pi.

And so on.

Here we have:

θ = x*(pi/2)

When x = 0, θ = 0.

And sin(θ) is increasing in θ = 0.

Then we must choose one of the options that start with x = 0.

now it will stop increasing when:

θ = pi/2 = x*(pi/4)

x = 2.

So the acceleration is increasing in the segment (0,2)

And it will start increase again when:

θ = (3/2)*pi = x*(pi/4)

(3/2)*pi*(4/pi) = 6 = x.

So at x= 6 the acceleration starts increasing again, and the acceleration is only deffined until x = 10, then

the correct option is: (0, 2) and (6, 10)

Ms. Carter has 30 boxes of books. Half of the boxes have 25 books and the other half have 50 books. How many books does she have

Nikitich [7]

15 x 25 = 375
15 x 50 = 750

375 + 750 = 1,125

She has 1,125 books.

Explain a thought process you might use when trying to find the additive or multiplicative inverse of a number or expression. ..

gizmo_the_mogwai [7]

Definition of additive inverse.- If two numbers are added together and the sum is zero, they are the additive inverse of each other.

......................................... IF A + B = 0 , they are the additive inverse of each other.


Multiplicative Inverse.- If two numbers are multiplied together and the product is one. They are the multiplicative inverse of each other, also called reciprocal. 

......................................... A.B = 1 , they are the multiplicative inverse of each other.


Example of: 

Additive inverses :................ 5 + ( - 5 ) = 0 

Multiplicative inverses...........5 x 1/5 = 1

Tricia recorded the number of pets owned by each of her classmates. these data points represent the results of her survey. 0, 3,

SOVA2 [1]

The dot plot of the data recorded by Tricia about number of pets owned by each of her classmates looks like scattered and some points are in one line.

Given number of pets owned by each of her classmates are: 0, 3, 2, 4, 1, 0, 0, 3, 2, 1, 2, 1, 1, 3, 4, 2, 0, 0, 1, 1, 1, 0, 3.

We have to create dot plot of the data given in the question.

Firstly we have to give a code to each value which represents friend of Tricia.

A dot plot is a statistical chart which have points but they are presented in dot form. Each dot shows a value .There are two common, yet different versions of the dot chart.

After giving codes the table will look like:
