The recursive rule that best describes the sequence 3, 14, 36, 80, ...is [tex]a_{n} =2a_{n-1} +8[/tex].
What is a sequence?A sequence is a particular order in which related things follow each other.
Let us cross-check the recursive rule [tex]a_{n} =2a_{n-1} +8[/tex]....(1)
Given sequence is: 3, 14, 36, 80, .....
Put n=1, 2, 3 in (1)
[tex]a_{2} =2a_1+8\\a_{2} =2*3+8\\a_{2} =14[/tex]
[tex]a_{3} =2a_2+8\\a_{3} =2*14+8\\a_{3} =36[/tex]
[tex]a_{4} =2a_3+8\\a_{4} =2*36+8\\a_{4} =80[/tex]
We are getting the sequence as 3, 14, 36, 80, ..... i.e. same as the given sequence.
Therefore, the recursive rule that best describes the sequence 3, 14, 36, 80, ...is [tex]a_{n} =2a_{n-1} +8[/tex].

Roberta bought 9/10 pound of raisins. She put 2/5 pound in bags for her lunch. How many 2/5 pound bags can Roberta fill? Does she have any left over?
Answers
Answer:
2 pound bags and have a remeinder of 1/10
Step-by-step explanation:
Answer:
She can fill 2 bags for her lunch and will have 1/10 pound left.
Step-by-step explanation:
It is easier if there is a common denominator, so I made the 2/5 into 4/10, so it is the same as 9/10 pound she bought.
4/10 is one bag, and if you double that, it is 8/10 pounds used. This is two bags of raisins for her lunch.
9/10 - 8/10 leaves 1/10 pound remaining, and not in a bag.

10b+45 = 6b+77
Okay Step 2: -6b from both sides and subtract 45 from both sides. Then your equation should look like...
2b = 32
Step 3: divide both sides by 2. Which should leave you with....
B=16
Now that we know B we have to plug it in so to solve for H the equation will be...
10(16)+45=205

The correct answer is A, 14%.
Step-by-step explanation:
All you have to do is take the 30% chance of you HAVING to stop at the first light and find the chance that you won't have to stop at the first light, which is 70%, or .7. Then you take the chance of having to stop at the second light which is 80%, and find the probability of NOT having to stop there, which is 20%, or .2. Then you multiply the probabilities of not having to stop, which equals .14.

The diagram shows a trapezium.

Diagram NOT
accurately drawn
2x
x + 5
All the measurements are in centimetres.
The area of the trapezium is 351 cm2.
(a) Show that 2x2 + x - 351 = 0
Answers
Answer:
Step-by-step explanation:
The area of a trapezium is given as;
Area = [tex]\frac{1}{2}[/tex](a + b)h
where: a is the length of the upper side, b is the length of its base and h is its height.
This implies that; a = x - 4, b = x + 5, h = 2x and area = 351
Thus,
351 = [tex]\frac{1}{2}[/tex]((x - 4) + (x + 50)) 2x
= (x - 4 + x + 5) x
531 = (2x + 1) x
= 2[tex]x^{2}[/tex] + x
So that;
2[tex]x^{2}[/tex] + x - 531 = 0
This gives a quadratic equation.

Which is an equation in point slope form for the given point and slope? Point: (-3,7) Slope: 4
Answers
Answer:
y-7=4x(x+3)
Step-by-step explanation:
(The 4x is 4 times ...)
Answer:
[tex]y -7 = 4(x+3)[/tex]
Step-by-step explanation:
Point-slope form is in the format of [tex]y-y_1 = m (x-x_1)[/tex]. When knowing a line's slope and a point it passes through, you can write an equation in that format. The [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] must be substituted for with real values.
The [tex]m[/tex] represents the slope, thus substitute 4 for [tex]m[/tex]. [tex]x_1[/tex] represents the x-value of one point the line passes through, while [tex]y_1[/tex] represents that same point's y-value. The line passes through (-3, 7), so substitute -3 for [tex]x_1[/tex] and 7 for [tex]y_1[/tex]. This gives the following answer and equation:
[tex]y-(7) = 4(x-(-3))\\y -7 = 4(x+3)[/tex]
