Answer:
7y=x
Step-by-step explanation:
Answer:
c =
- d
Step-by-step explanation:
Multiply both sides by 2 to eliminate the fraction
2A = b(c + d) ← divide both sides by b
= c + d ← subtract d from both sides
- d = c
The number of pieces of card stock which would result upon the process repetition is; 256 pieces.
<h3>What is the number of card stock pieces resulting from the cutting process?</h3>
According to the task content, it follows that since, there are 8 pieces of the 8 inches per side cards initially, the resulting number of cards after carrying out the process of cutting cards into half five, 5 times is;
No of cards = 8 (2)⁵
No. of cards = 256 pieces.
The size of each of the cards in discuss provided that all cuts will be made along and not across the longer edge is; 8 by 1/4 inches.

<u>QUESTION 1</u>
The given data set for the expenditure is

The formula for calculating the mean is given by,

We need to add all the expenditure and divide by the total number of days.

This gives us,

to the nearest hundredth.
<u>QUESTION 2</u>
The standard deviation of the data set is given by the formula;

This implies that,

This will give us,




to the nearest hundredth,
.
<u>QUESTION 3</u>
The variance is the square of the standard deviation.


To the nearest hundred gives,

Answer:
Acceleration of the particle = 
Step-by-step explanation:
We are given the position vector of a particle moving in a circle of radius b units.
r(t) = b cos(ωt)i + b sin(ωt)j
Velocity , v =
= -bω sin(ωt)i + bω cos(ωt)j
The magnitude of velocity, v =
Squaring both sides,

Since
= 1

The acceleration towards the centre is called the centripetal acceleration and is given by
a = 
a = 
a =
