Hello

Can I please have help with the following question:

The Shy Family

A breakfast ceral company is having a special promotion. They are gibing away a figurine in every pack. There are six figurines to collect: Ashy, Bishy, Cashy, Dishy, Eshy and flushy.

Design a simulation to determine how many packets of cereal you would need to buy to collect all 6 figurines.

1.Each packet has only one figurine
2. You cannot swap figurines with other people
3. You may not onpern packets without buying them
4. Every figurine has ann equal chance of behing in a packet

Prompt questions: What is the probability of getting the six figurines in less than ten packests? 20 packets.

Extend this in some way.

What is the most suitable simulation I should do and how do I set it out.

Thank you

Help is greatly appreciated

Q.1 Find the value of x in the diagrams below

shown in the uploaded image

I think you use the cosine rule:  Cos A=b^2+ C^2-a^2/2bc     

Q.2
A sailing course is typically set out in triangle formation. From a start point two markers (A and B) have been positioned to form a triangle for the sailing course. Marker A is on a bearing of 30º and is 2.5 km from the start. Marker B is an angle of 100º from the start and is positioned 3.2 km from the site.

a) Draw a diagram to represent the course
b)Find the total length of the course

I don’t know how to simply draw the diagram to represent the course but I am guessing that for b) you use the sine rule to a/sin⁡〖A 〗 =b/sin⁡B =c/(Sin C)

Thank you for any help

Hello

How can you determine the affects of changing the a, b and c values in quadratic, cubic, exponential and recprical equations without graphing them.

I know the basics that in quadratics changing the 'a' stretches sthe graph vertically, changing the 'b' value translates the graph horizontally and changin the graph in 'c' translates the graph vertically.

In my assighment I had to describe the effects of the exponential function y= 3^x which changes to y= 4^x

The answers is: The graph rises faster in quad 1, falls faster in quad 2. y intercept remains 1

I know how the y-interecepts remains one but how do you determine if the graph rises faster in quad one ect.

The other one was y= (x+2)^2-3 was altered to y= (x-3)^2 +2

The answer: The turning point moves from (-2, -3) to (3,2). Graph moves 5 units right and 5 units up.

How do you determine those decriptions.

How would you describe the affects for other functions such as cubics and reciprical functions.

Thank you

Thank you for the help for my previous questions, this is the best forum to get help for maths.

Hello

How do you solve the following simultaneous equations? (do you solve it by elimination method or subtitution method)

2y + x = 10 and x= 3 + 5y

Thank you

Hello

I am having trouble understanding exponential functions.
What does the formula F(x)= 4x mean and how do you work out the questions for Q.1 (b) by using the graph.

Help will be greatly appreciated

Thank you

Hi everyone

I have a test on Friday on geometric, artithmetic and Fibonacci sequences and I was givin a booklet which is essential to study for the test. I am stuck on the the very last question which is below and on the picture of the table.

Question: Investigate the following results and find rules in terms of Fibonacci number.

I have to fill in the table by using the rule Fn  (Fn+1 + Fn-1) and
finish the rule Fn  (Fn+1 + Fn-1) = ?

Thank you, I will greatly appreciate the help

Hi everyone

I am a highschool student and I love science, I find it very interesting especially Chemistry.
When I found this excellent maths site I thought everyone was very friendly bunch and enjoy helping people with maths so I thought this is the perfect maths forum. I am looking foward to get to know you all and I think I will enjoy maths even more.

Thank you
