Answer:
[tex]f(n) = 3T_{n-1}[/tex]; [tex]T_1 = 12[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 4*3^x[/tex]
Required
Write as a recursive function
Substitute 1 for x.
[tex]f(1) = 4*3^1 = 4 * 3 = 12[/tex]
[tex]f(2) = 4*3^2 = 4 * 9 = 36 = 12 * 3[/tex]
[tex]f(3) = 4*3^3 = 4 * 27 = 108 = 36 * 3[/tex]
Following the above pattern:
[tex]f(n) = T_{n-1} * 3[/tex]
[tex]f(n) = 3T_{n-1}[/tex]
Hence, the recursive function is:
[tex]f(n) = 3T_{n-1}[/tex]; [tex]T_1 = 12[/tex]

What is 7/9 as a decimal rounded to 3 decimal places?
Answer:
7 ÷ 9 = 0.77777777777
= 0.778
The given fraction 7/9 as a decimal rounded to 3 decimal places is 0.778.
What is the fraction?A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
To convert a fraction to a decimal, we need to divide the numerator by the denominator.
Here, we have:
7/9 = 0.777777...
7 divided by 9 gives us a repeating decimal of 0.7777777... and so on.
To round this to 3 decimal places, we need to look at the fourth decimal place. If it is 5 or greater, we round up the third decimal place. If it is less than 5, we simply leave the third decimal place as is.
In this case, the fourth decimal place is a 7, which means we need to round up the third decimal place.
Therefore, 7/9 as a decimal rounded to 3 decimal places is 0.778.

Find the perimeter of rectangle LINT.
Answer:
[tex]P = 22.75[/tex]
Step-by-step explanation:
Given:
See attachment for rectangle LINT
Required
Calculate its perimeter
From the attachment:
Considering triangle LYT, we apply Pythagoras theorem.
[tex]LT^2 = LY^2 + TY^2[/tex]
Where:
[tex]LY = 5.2[/tex]
[tex]TY = 3.9[/tex]
The formula becomes:
[tex]LT^2 = 5.2^2 + 3.9^2[/tex]
[tex]LT^2 = 42.25[/tex]
Take positive square root of both sides
[tex]LT = \sqrt{42.25[/tex]
[tex]LT = 6.5[/tex]
Next, we calculate the length of NT.
By comparing triangles LYT and NYT
We make use of the following equivalent ratios to solve for NT
[tex]NT:TY = LT:LY[/tex]
[tex]NT : 3.9 = 6.5 : 5.2[/tex]
Convert to fractions
[tex]\frac{NT}{3.9} = \frac{6.5}{5.2}[/tex]
Make NT, the subject:
[tex]NT = \frac{6.5}{5.2}*3.9[/tex]
[tex]NT = \frac{6.5*3.9}{5.2}[/tex]
[tex]NT = \frac{25.35}{5.2}[/tex]
[tex]NT = 4.875[/tex]
The perimeter (P) is then calculated as:
[tex]P = NT + LT + LI + NI[/tex]
Where
[tex]NT = LI[/tex] and [tex]LT = NI[/tex] -- opposite sides of rectangle.
So:
[tex]P = NT + NT + LT + LT[/tex]
[tex]P = 2NT + 2LT[/tex]
Substitute values for NT and LT
[tex]P = 2*4.875 + 2*6.5[/tex]
[tex]P = 9.75 + 13.0[/tex]
[tex]P = 22.75[/tex]
Hence, the perimeter is 22.75 units

A warehouse has shelves that can hold 8, 12 or 16 each shelf has section holding the same number of skateboards. What is the greatest number of skate boards that can be put in a section
Answer:
4 skate boards
Step-by-step explanation:
We solve this question using Greatest Common Factor method
We find the factors of 8, 12 and 16
The factors of 8 are: 1, 2, 4, 8
The factors of 12 are: 1, 2, 3, 4, 6, 12
The factors of 16 are: 1, 2, 4, 8, 16
Then the greatest common factor is 4.
Thereeft, ,the greatest number of skate boards that can be put in a section is 4 skate boards

During the last schools football game, the Home Team scored 13 more points than the Visiting
denm. The total of their scores was 47. How many points did each team score?
Answer:
Home 30, visitor 17.
Step-by-step explanation:
Visiting team score is x. Home score is then x+13. Total of both is 47 so...
x+(x+13)=47
2x+13=47
2x-34
x=17
x+13=30
The score of Home Team is 30 points.
The score of Visiting team is 17 points.
Here,
During the last schools football game, the Home Team scored 13 more points than the Visiting team.
The total of their scores was 47.
We have to find points of each team score.
What is Number system?
A number system is a system representing numbers. It is also called the system of numeration.
Now,
Let Visiting team score x points.
Then, Home team score is 13 more points than the Visiting team.
Home team score x + 13 points.
The total of their scores was 47.
Hence,
x + (x + 13) = 47
2x + 13 = 47
2x = 47 - 13
2x = 34
x = 17
So, The score of Visiting team is 17 points.
And, The score of Home Team = 17 + 13 = 30 points.

1 The length of a rectangle is 10 inches, and the
width is represented by 3x. Which best
represents an equation and solution for x if the
area of the rectangle is 40 square inches?
A 10(3x) = 40; X = 4
B 30x = 40; x = 1;
C 3x = 40; x = 13
D 3x + 10 = 40; X = 10
Answer:
A
Step-by-step explanation:
To find the area of a rectangle, it is length times width (10*3x), and if it equals 40, you could just write that after the equation, and then find out that "x" would equal [tex]\frac{4}{3}[/tex]
Answer:
30x = 40 ; x ≈ 1
Step-by-step explanation:
[tex]A^{}[/tex] = [tex]l^{}[/tex] [tex]w^{}[/tex]
[tex]l^{}[/tex] = 10 inch.
[tex]w^{}[/tex] = 3x
10(3x) = 40
30x = 40 ; x = [tex]1\frac{1}{3}[/tex] ≈ 1

find the coordinates of the missing endpoint if m is the midpoint of ab. a(-9, -4) and m(-7, -2.5)
Answer:
The coordinates of the point b are:
b(x₂, y₂) = (-5, -1)
Step-by-step explanation:
Given
As m is the midpoint, so
m(x, y) = m (-7, -2.5)
The other point a is given by
a(x₁, y₁) = a(-9, -4)
To determine
We need to determine the coordinates of the point b
= ?
Using the midpoint formula
[tex]\left(x,\:y\right)=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
substituting (x, y) = (-7, -2.5), (x₁, y₁) = (-9, -4)
[tex]\left(-7,\:-2.5\right)=\left(\frac{x_2+\left(-9\right)}{2},\:\:\frac{y_2+\left(-4\right)}{2}\right)[/tex]
Thus equvating,
Determining the x-coordinate of b
[x₂ + (-9)] / 2 = -7
x₂ + (-9) = -14
x₂ - 9 = -14
adding 9 to both sides
x₂ - 9 + 9 = -14 + 9
x₂ = -5
Determining the y-coordinate of b
[y₂ + (-4)] / 2 = -2.5
y₂ + (-4) = -2.5(2)
y₂ - 4 = -5
adding 4 to both sides
y₂ - 4 + 4 = -5 + 4
y₂ = -1
Therefore, the coordinates of the point b are:
b(x₂, y₂) = (-5, -1)
