Answer:
[tex]f(n) = 5 + f(n - 1)[/tex]
Step-by-step explanation:
Given
[tex]f(n) = 5n - 2[/tex]
Required
Write a recursive expression
[tex]f(n) = 5n - 2[/tex]
When n = 1
[tex]f(1) = 5 * 1 - 2 = 5 - 2 = 3[/tex]
[tex]f(1) = 3[/tex]
When n = 2
[tex]f(2) = 5 * 2 - 2 = 10 - 2 = 8[/tex]
[tex]f(2) = 8[/tex] can be rewritten as
[tex]f(2) = 5 + 3[/tex]
Substitute 3 for f(1)
[tex]f(2) = 5 + f(1)[/tex]
Express 1 as 2 - 1
[tex]f(2) = 5 + f(2-1)[/tex] ----- (1)
When n = 3
[tex]f(3) = 5 * 3 - 2 = 15 - 2 = 13[/tex]
[tex]f(3) = 13[/tex] can be rewritten as
[tex]f(3) = 5 + 8[/tex]
Substitute 8 for f(2)
[tex]f(3) = 5 + f(2)[/tex]
Express 2 as 3 - 1
[tex]f(3) = 5 + f(3 - 1)[/tex] ------ (2)
Write out (1) and (2)
[tex]f(2) = 5 + f(2-1)[/tex]
[tex]f(3) = 5 + f(3 - 1)[/tex]
Replace 2 and 3 with n in both cases; This gives
[tex]f(n) = 5 + f(n - 1)[/tex]
Hence;
The recursive is [tex]f(n) = 5 + f(n - 1)[/tex]
[tex]8 + 3 \times 4[/tex]

A container holds an unknown number of pints of water. Let p represent this unknown amount. Nari pours three-fourths of this volume into an empty pot. She then adds another 2 pints of water. The pot now holds a total of 11pints of water. Set up and solve an equation to find the value of p.
Answer: 12
Step-by-step explanation:
Let p represent this unknown amount.
Nari pours three-fourths of this volume into an empty pot. This can be written as:= 3/4 × p = 3/4p = 0.75p
She then adds another 2 pints of water and the pot now holds a total of 11pints of water. This means we will add 2 to 0.75p and equate to 11. This will be:
0.75p + 2 = 11
0.75p = 11 - 2
0.75p = 9
p = 9/0.75
p = 12
P equals to 12
This question is based on solving linear equation.Therefore, the answer is 12 pints of total amount of water.
Given:
Nari pours three-fourths of this volume into an empty pot.She then adds another 2 pints of water. The pot now holds a total of 11 pints of water.
Let the unknown amount of pints of water is p.
According to the question,
She pours three-fourths of this volume into an empty pot. This can be written as:
[tex]\dfrac{3}{4}\times p= \dfrac{3}{4} p = \bold{0.75p}[/tex]
She add on 2 pints of water to 0.75 p in pot, then it becomes total of 11 pints of water.
In ,mathematically expressed as,
[tex]\begin{alligned}0.75p+2&=11\\0.75p&=11-2\\0.75p&=9\\p&=\frac{9}{0.75}\\\bold{p&=12}\end{alligned}[/tex]
Therefore, there is total amount of 12 pints water.

This question is not complete
Complete Question
Students in a pre-algebra class are given the polynomial 12x²y - 6xy +18y² and told to factor out the greatest common factor.
Which student has made the correct choice? (1 point)
a) Delia chose 3y because she said that it was a factor of every term.
b) Pedro chose y because he said that the greatest common factor can be found only by looking at the variable terms.
c) Mike chose 6y because he said that it was the largest factor of every term. d) Marisol chose 6 because she said that it was the only greatest common factor in each term.
Answer:
c) Mike chose 6y because he said that it was the largest factor of every term.
Step-by-step explanation:
Step 1
Identify the GCF of the coefficients.
12x²y - 6xy + 18y²
Coefficients are :
12, 6, 18
The Greatest Common Factor for 12, 6, 18 =
The factors of 6 are: 1, 2, 3, 6
The factors of 12 are: 1, 2, 3, 4, 6, 12
The factors of 18 are: 1, 2, 3, 6, 9, 18
Then the greatest common factor is 6.
Step 2
Identify the GCF of the variables.
x²y , xy, y²
The GCF of these variables is y
Step 3
Combine to both GCF's to obtain the GCF of the expression.
= 6 × y
= 6y
The Greatest Common Factor for the expression 12x²y−6xy + 18y² is 6y
Step 4
We factorise
= 12x²y−6xy + 18y²
= 6y(2x² - x + 3y)
Therefore, Option c) Mike chose 6y because he said that it was the largest factor of every term is the correct option.
Mike is correct.

$1,547.76. How much money do they still need to make to break even?
Answer:
7212.53, i belive
Step-by-step explanation:
56 x 6.33 = 354.48
91 x 2.85 = 259.35
259.35 + 354.48 = 613.83
1547.76 - 613.83 = 933.93
6278.60 + 933.93 = 7212.53

The area of a trapezoid is given by the formula ...
A = 1/2(b1 +b2)h
The bases are the parallel line segments, and the height is the perpendicular distance between them.
A = (1/2)(7 m + 5 m)(3 m) = 1/2(12 m)(3 m) = 18 m^2
The area of the trapezoid is 18 square meters.

A container is 1/3 full of water and 1/4 of oil. What fraction of the container is empty?
Just subtract the sum of 1/4 and 1/3 on 1
.
1 - [(1/3) + (1/4)]
Get the least common denominator. LCD = 12
= 12/12 - [(4/12) + (3/12)]
= 12/12 - (7/12)
= 5/12
.
Therefore, 5/12 of the tank is empty.

Solve for h
3/7=h/14-2/7
Answer:
h =10
Step-by-step explanation:
3/7 = h/14 -2\7
3/7 = 1/14 h + -2/7
1/14 h + -2/7 = 3/7
1/14 h + -2/7 +2/7 = 3/7 + 2/7
1/14 h = 5/7
14 * ( 1/14h) = 14* (5/7)
h =10

Line GH bisects angle FGI, that means angle FGH = angle HGI
To Find:the value of x and angle FGI
Solution:angle FGH = angle HGI
6x - 11 = 4x + 7
or, 6x - 4x = 7 + 11
or, 2x = 18
or, x = 18/2 = 9
angle FGI = angle FGH + angle HGI
or, angle FGI = 6x - 11 + 4x + 7
or, angle FGI = 10x - 4
By putting the value of x, we get
angle FGI = 10(9) - 4
or, angle FGI = 90 - 4 = 86°
Answer:The value of x is 9.
Angle FGI = 86°

Sam John
-3 - 14 = -3 + 14 -3 - 14 = -3 + (-14)
=11 = -17
Describe how you got the answer PLZS
Answer:
-17
Step-by-step explanation:
ok well I can't really see Sam and John's answer but -3-14 is equal to -17
if you see that there's a negative in front of the first number and its also subtracting you have to make that subtract sign an addition sign then change the second number to a negative like this:
-3+-14 then you just add.
With Sam and John whichever one had -17 as their answer is correct
