Recursive Sequence Function
A recursive sequence is a sequence of numbers whose values are determined by the numbers that come before them in the sequence.
We’re given a sequence whose (n + 1)-th term f(n + 1) depends on the value of the n-th term f(n), specified by the recursive rule
f(n + 1) = -4 f(n) + 3
We’re also given the 1st term in the sequence, f(1) = 1. Using this value and the recursive rule, we can find the next term f(2). (Just replace n with 1.)
f(1 + 1) = -4 f(1) + 3
f(2) = -4 • 1 + 3
f(2) = -1
We do the same thing to find the next term f(3) :
f(2 + 1) = -4 f(2) + 3
f(3) = -4 • (-1) + 3
f(3) = 7
One more time to find the next term f(4) :
f(3 + 1) = -4 f(3) + 3
f(4) = -4 • 7 + 3
f(4) = -25

Little Tommie sees two triangles on his test. He is asked if the two triangles are similar by SAS similarity. His response is "Yes!" Is Little Tommie correct? Explain in at least three sentences.
Answer:
Yes
Step-by-step explanation:
Side 2 squared is side 4Side 3 squared is side 9since both those sides are similar , the angle between them is the sameFor every quarter spent, Reggie receives 50 food pebbles to feed the fish at a hatchery. Reggie has thrown 350 food pebbles into the fish pools. Find the number of quarters Reggie spent at the hatchery. (Please use a label with this solution) *
Answer:
Reggie has spent
Step-by-step explanation:
7 quarters
Answer:
7 quarters
Step-by-step explanation:
We know that for every quarter, Reggie would receive 50 food pebbles, we also know that he has thrown 350 food pebbles into fish pools. So let's create an equation, q is for the quarters.
50(q) = 350
Since every quarter gives Reggie 50 food pebbles, then the q variable will go next to 50, and since we need to reach the total amount of 350, we put it on the opposite side.
Solve for q by isolating it, divide 50 from both sides:
[tex]\frac{50q}{50} =\frac{350}{50}[/tex]
[tex]q = 7[/tex]
Therefore, Reggie used 7 quarters for 350 food pebbles.

Answer/Step-by-step explanation:
If the vertical line touches the graph at more than one point, then the graph is not a function.Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function.
[RevyBreeze]
Yes it's a function
As per the defination of function.
If every domain of the relationship has an unique range that's a function
f(x)=ySo
Here
f(0)=0And rest also have unique range
So it's a function
The Gift Basket Store had the following premade gift baskets containing the following combinations in stock. Cookies Mugs Candy Coffee 20 13 10 Tea 12 10 12 Choose 1 basket at random. Find the probability that it contains a. Coffee or candy b. Tea given that it contains mugs c. Tea and cookies
Using it's concept, it is found that the probabilities are:
a. 0.7143 = 71.43% probability that is contains coffee or candy.
b. 0.4348 = 43.48% probability that it contains tea, given that it contain mugs.
c. 0.1558 = 15.58% probability it contains tea and cookies.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Item a:
There is a total of 20 + 13 + 10 + 12 + 10 + 12 = 77 baskets, of which 20 + 13 + 10 + 12 = 55 contain coffee or candy, hence:
[tex]p = \frac{55}{77} = 0.7143[/tex]
0.7143 = 71.43% probability that is contains coffee or candy.
Item b:
13 + 10 = 23 contain mugs, of which 10 contain tea, hence:
[tex]p = \frac{10}{23} = 0.4348[/tex]
0.4348 = 43.48% probability that it contains tea, given that it contain mugs.
Item c:
Out of the 77, 12 contain tea and cookies, hence:
[tex]p = \frac{12}{77} = 0.1558[/tex]
0.1558 = 15.58% probability it contains tea and cookies.

Seven boys hire DVD's and each pays R5,50. If 4 friends join in, how much will they each pay then?
Seven boys hire DVD's and each pays R5,50
I assume R 5.50 ( R to be the currency)
also assuming that they dont hire any more DVDs
total amount paid by 7 boys
= 5.50 × 7
= 38.5
when 4 more friends join the amount should get divided by 11 ( 7 + 4 )
so each has to pay an amount of 38.5 / 11 = 3.5
I think my assumptions here were correct
if not
let me know :)
Explain the steps you use to solve the equation: 2(x-2) =26
Solution:
Simplify the distributive property and solve.
2(x - 2) = 26=> 2x - 4 = 26=> 2x = 26 + 4=> 2x = 30=> x = 15The solution to the equation is 15.
Your required solution :
Let us solve this equation..!!
Firstly multiplying 2 by (x - 2)
⇒ 2 × (x - 2) = 26
⇒ 2x - 4 = 26
On transposing -4 to R.H.S. it would be positive,
⇒ 2x = 26 + 4
⇒ 2x = 30
On dividing 30 by 2 we gets,
⇒ x = 30/2
⇒ x = 15
Therefore, value of x is 15.

1) The sum of the two numbers is 36 and their difference is 9. Find the average of the two numbers.
Answer:
22.5 and 13.5 are the numbers. average of both numbers is 18.
Step-by-step explanation:
Given that there are two numbers.
let them be, x and y
using the unknown numbers,
x + y = 36x - y = 9make x the subject:
x + y = 36x = 36 - y ..........equation 1 x - y = 9x = 9 + y ..........equation 2Solve them simultaneously:
9 + y = 36 - yy + y = 36 - 92y = 27y = 13.5Then another number, x:
x = 9 + yx = 9 + 13.5x =22.5Average:
( sum of both the numbers ) ÷ 2( 22.5 + 13.5 ) ÷ 218
Let the two numbers be x and y
x+y = 36 -----(1)
x - y = = 9-----(2)
(1)+(2)
x +y = 36
x - y = 9
---------------
2x = 45
x = 45/2
Then y =?
x - y =9
45/2 - y =9
y = 45/2-9
y = (45-18)/2
y = 27/2
The two numbers are 45/2 and 27/2
Sue has 18 sweets.
Tony also has 18 sweets.
Sue gives Tony x sweets.
Sue then eats 5 of her sweets.
Tony eats half of his sweets.
Write an expression for the number of sweets Sue and Tony have?
Answer:
see below
Step-by-step explanation:
18 - x - 5 = for sue
(18 + x)/2 = for tony
to put the combined total together
18 - x - 5 + (18 + x)/2
well the X's cancel out since it stays between them
18 - 5 + (18)/2
18 - 5 + 9
18 + 4
