If a1=5 and an= -5an-1 then find the value of a5.
Answer:
The value of a5 is 3125
Step-by-step explanation:
Recursive Sequence
It refers to the sequences where each term is given as a rule that depends on one or more of the previous terms, unlike explicit sequences where a general term is given and we can calculate any term without knowing the value of the previous terms, except for the first one.
The sequence is given as:
[tex]a_1=5[/tex]
[tex]a_n=-5a_{n-1}[/tex]
To find the value of a5, we need to find the previous terms first:
[tex]a_2=-5a_{1}=-5*5=-25[/tex]
[tex]a_3=-5a_{2}=-5*(-25)=125[/tex]
[tex]a_4=-5a_{3}=-5*125=-625[/tex]
[tex]a_5=-5a_{4}=-5*(-625)=3125[/tex]
The value of a5 is 3125

Step-by-step explanation:
The volume of a fish tank is given by the function V (x) = (x + 7) (1-4) (2x + 3). Write a function describing a fish tank that has the same height but is
longer in length by 3 units and wider by 2 units.
Answer:
V(x)=(x+9) * (3) * (2x + 6)
Step-by-step explanation:
A fish tank is usually made in the shape of a 3-Dimensional rectangular prism. The volume of this shape can be obtained by using the following formula
V = w * h * l
in this formula w represents the width, h represents the heigh, l represents the length, and V represents the volume of the rectangular prism/fish tank. Therefore, we can use the function provided in the question and simply add 3 units to the length and 2 units to the width in order for it to work for our new fish tank.
V(x)=(x+9) * (3) * (2x + 6)

Formula:
Slope:
Answer:
see below
Step-by-step explanation:
slope = (y₂ - y₁) / (x₂ - x₁) <=== formula
= (2 - (-7)) / (18 - 18)
= 9 / 0

Fifteen billiard balls are numbered 1 to 15. One billiard ball is selected at random. Determine the odds for and the odds against for (6 Points) a) selecting the number 7 b) selecting a number greater than 10
Answer:
Odds for & against selecting number 7 = 1/14 & 14
Odds for & against selecting number more than 10 = 4/11 & 11/4
Step-by-step explanation:
Odds for event = Prob (event) / Prob (no event)
Odds against event = Prob (no event) / Prob (event)
Odds for selecting number 7Prob (No. 7 chosen) = 1/15 , Prob (No. 7 not chosen) = 14/15
Odds for number 7 = (1/15) ÷ (14/15) = 1/14
Odds against number 7 = (14 / 15) ÷ (1/15) = 14
Odds for selecting number > 10Prob (No. > 10 chosen) = 4 / 15 , Prob (No. > 10 not chosen) = 11/15
Odds for No. > 10 = (4/15) ÷ (11/15) = 4/11
Odds against No. > 10 = (11/15) ÷ (4/15) = 11/4

Misty correctly determined the equation of the linear function represented by the table of values below to be y = negative 2 x + 9 in slope-intercept form by using the ordered pairs (1, 7) and (2, 5).
Answer:
we can verify that the determined equation is the same as the equation determines by Misty, hence, we conclude that Misty had correctly determined the equation of the linear function.
Step-by-step explanation:
As Misty determined the equation of linear function:
[tex]y=-2x+9[/tex]
We need to check whether she has got the correct equation or not.
As the linear equation passes through the points [tex](1, 7)[/tex] and [tex](2, 5)[/tex].
Finding the slope:
The slope between two points [tex](1, 7)[/tex] and [tex](2, 5)[/tex]
[tex]\left(x_1,\:y_1\right)=\left(1,\:7\right),\:\left(x_2,\:y_2\right)=\left(2,\:5\right)[/tex]
[tex]m=\frac{5-7}{2-1}[/tex]
[tex]m=-2[/tex]
As we know the point-slope form is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
So, the equation of the line will be:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-5=-2\left(x-2\right)[/tex]
Add 5 to both sides
[tex]y-5+5=-2\left(x-2\right)+5[/tex]
[tex]y=-2x+9[/tex]
From the above calculation, we can verify that the determined equation is the same as the equation determines by Misty, hence, we conclude that Misty had correctly determined the equation of the linear function.
3 8 of your income is spent on your monthly bills, 2 5 is spent on food and clothing and 1 10 goes on entertainment. You put the remainder of your monthly income into savings.
Answer:
Fraction of saving = 1/8
Step-by-step explanation:
Given:
Spent on bills = 3/8
Spend on food = 2/5
Spend on entertainment = 1/10
Find:
Fraction of saving
Computation:
Fraction of saving = 1 - Spent on bills - Spend on food - Spend on entertainment
Fraction of saving = 1 - 3/8 - 2/5 - 1/10
By taking LCM
Fraction of saving = [40 - 15 - 16 - 4]/40
Fraction of saving = [5]/40
Fraction of saving = 1/8

B. f(x) = 0.05x; $5.50
C. FX) 5 + x;$111.05
D. f(x) = x - 5; $108.95
Answer:
f(x) = .05x; $5.50
Step-by-step explanation:
f(x) = .05x
f(110) = .05(110) = $5.50
A local florist charges $15 for delivery plus $2.75 per flower for all flower arrangements. When Marcus got the bill for a flower arrangement he ordered, it was less than $50. Which of the following could not represent the number of flowers in the arrangement Marcus ordered?
Answer:
Step-by-step explanation:
Step one:
given
All Charges
$15 for delivery
and $2.75 per flower
let the number of flowers delivered be x
and the total charges for x flowers be y
the linear function for the total charges is
y=2.75x+15
Step two:
when y=$50
50=2.75x+15
50-15=2.75x
35=2.75x
divide both sides by 2.75
x=35/2.75
x=12.72
Note: we are not given the options. We only solved for the flower arrangements
Therefore the number of flowers in the arrangement Marcus ordered
is 12.72 flowers

You are carpeting a room in a house for your job. You have a boss that likes to play jokes, so instead of just giving you the dimensions of the room, he tells you the dimensions in rational expressions. The length of the room is fraction numerator x squared minus x minus 6 over denominator x minus 5 end fractionand the width of the room is fraction numerator x squared minus 6 x plus 5 over denominator x plus 2 end fraction. What is the area of the room in terms of x? How much carpet do you need if x = 10?
Answer:
[tex]x^2-4x+3[/tex]
[tex]63\ \text{sq. units}[/tex]
Step-by-step explanation:
l = Length = [tex]\dfrac{x^2-x-6}{x-5}[/tex]
w = Width = [tex]\dfrac{x^2-6x+5}{x+2}[/tex]
Area is given by
[tex]A=lw\\\Rightarrow A=\dfrac{x^2-x-6}{x-5}\times\dfrac{x^2-6x+5}{x+2}\\\Rightarrow A=\dfrac{x^2-3x+2x-6}{x-5}\times\dfrac{x^2-5x-1x+5}{x+2}\\\Rightarrow A=\dfrac{(x-3)(x+2)}{x-5}\times\dfrac{(x-5)(x-1)}{x+2}\\\Rightarrow A=(x-3)(x-1)\\\Rightarrow A=x^2-4x+3[/tex]
Area of the room is [tex]x^2-4x+3[/tex].
If [tex]x=10[/tex]
Area of the room
[tex]A=x^2-4x+3=10^2-4\times 10+3\\\Rightarrow A=63\ \text{sq. units}[/tex]
So, the amount of carpet needed would be [tex]63\ \text{sq. units}[/tex].

Each lap around the park is 0.58 mile. Jessica walked 3.25 laps around the park. How many miles did Jessica walk around the park?
Answer:
5 miles but she did walk part of another mile so that would be 5.35.
Step-by-step explanation:
you can take 3.25 and subtract that by 0.58 until you can't do it anymore. Also I didn't know if you wanted the exact amount which would be 5.35 but total miles is only 5. Hope this helps!
Part A). Emily participates in a trivia quiz show. In each round, 20 points are awarded for a correct answer and 10 points are deducted for an incorrect answer. Part B). Emily answer 4 questions correctly and 11 incorrectly in the first round what was her score in the first round? Emily answer'd 7 questions correct and 8 incorrect in the second round what was her score in the second round.
Answer
A. -30 points
B. 60 points
Step-by-step explanation:
20 points for correct answer and 10 points deducted for wrong answer
Each deduction is -10 while each correct answer gives + 20
4 questions correctly and 11 incorrectly
= 4(20) + 11(-10)
= 80-110 = -30 points
Second round
7 correct, 8 incorrect
= 7(20) - 8(10)
= 140-80 = 60 points

Evaluate 7 to the power of 2 pls help
Answer:
49
Step-by-step explanation:
Whenever you power something, you are just multiplying that number by itself amount of times you are powering
7 to the power of 2 is 7² = 49
The power (or exponent) of a number define how many times to use the number in a multiplication.
It is written as like a small number to the right and above the base number.
In this example the little "2" says to use 8 two times in a multiplication: 82 = 8 × 8 = 64.
To evaluate 7 to the power of 2.
7² = 7 × 7 = 49
Therefore, 7 to the power of 2 is 49.
