Answer:

f(20) = 168

Step-by-step explanation:

To find the 20th term, substitute n = 20 into f(n) , that is

f(20) = 9(20) - 12 = 180 - 12 = 168

Explanation:

The two angles shown are vertical angles. This occurs whenever you have an X shape like this, and whenever the angles are opposite one another. Vertical angles are always congruent.

6x+7 = 8x-17

x = -24/(-2)

x = 12

Answer:

x = 2

Step-by-step explanation:

The volume (V) of a cuboid is calculated as

V = lbh ( l is length, b is breadth, h is height )

Here l = 10x , b = [tex]\frac{7}{4}[/tex] , h = 2 , then

V = 10x × [tex]\frac{7}{4}[/tex] × 2 = 70 , that is

20x × [tex]\frac{7}{4}[/tex] = 70

5x × 7 = 70

35x = 70 ( divide both sides by 35 )

x = 2

Answer:

[tex]x=2[/tex]

Step-by-step explanation:

Since L × W × H = V, we get

[tex]10x*\frac{7}{4}*2=70\\10x*\frac{7}{4}=35\\10x=20\\x=2[/tex]

Answer:

  x -2y = 14

Step-by-step explanation:

The x- and y-coefficients can be the same. The constant needs to change to make the given point satisfy the equation.

  x -2y = (2) -2(-6) . . . . . use (x, y) = (2, -6) to find the constant

  x -2y = 14

An arithmetic progression is a sequence that has a common difference between consecutive terms.

Question 6:

The recursive function is given as:

[tex]f(0) = 19\\f(n) = f(n - 1) -6;[/tex]     for [tex]n \ge 1[/tex]

The definition of nth term is given as:

[tex]f(n) = 19 - 6n[/tex]  for [tex]n > 0[/tex]

A proof that the functions represent the same sequence is as follows:

Set [tex]n=1[/tex] in

[tex]f(0) = 19\\f(n) = f(n - 1) -6;[/tex]

[tex]f(1) = f(1 -1) - 6 = f(0) - 6[/tex]

[tex]f(1) = 19 - 6 = 13[/tex]

Set [tex]n = 2[/tex]

[tex]f(2) = f(2 -1) - 6 = f(1) - 6[/tex]

[tex]f(2) = 13 - 6 = 7[/tex]

Set [tex]n = 3[/tex]

[tex]f(3) = f(3 -1) - 6 = f(2) - 6[/tex]

[tex]f(3) = 7 - 6 = 1[/tex]

Write out the equations

[tex]f(1) = 19 - 6 = 13[/tex]

[tex]f(2) = 13 - 6 = 7[/tex]

[tex]f(3) = 7 - 6 = 1[/tex]

Rewrite as:

[tex]f(1) = 19 - 6 = 13[/tex]

[tex]f(2) = 19 - 6 - 6 = 7[/tex]

[tex]f(3) = 19 - 6 - 6 -6= 1[/tex]

Rewrite again as:

[tex]f(1) = 19 -6\times 1 = 13[/tex]

[tex]f(2) = 19 -6\times 2 = 7[/tex]

[tex]f(3) = 19 -6\times 3 = 1[/tex]

Replace the numbers in brackets with n

[tex]f(n) = 19 -6\times n[/tex]

[tex]f(n) = 19 -6n[/tex]

Hence, it is proved that

[tex]f(n) = 19 -6n[/tex] and

[tex]f(0) = 19\\f(n) = f(n - 1) -6;[/tex]  represents the same sequence

The definition I will choose for f(20) is:

[tex]f(20) = 19 - 6 \times 20[/tex]

This is gotten from [tex]f(n) = 19 -6n[/tex].

I choose the definition because it is faster to calculate f(20) directly, than using recursion

Question 7:

Given that:

[tex]T_1 = 20[/tex]

[tex]T_2 = 16[/tex]

First, we calculate the common difference

[tex]d = T_2 - T_1[/tex]

[tex]d = 16 - 20 =-4[/tex]

The 500th term is then calculated using the nth term of an arithmetic progression formula.

[tex]T_n = T_1 + (n - 1) \times d[/tex]

So, we have:

[tex]T_{500} = 20+ (500 - 1) \times -4[/tex]

[tex]T_{500} = 20+ 499 \times -4[/tex]

[tex]T_{500} = 20 -1996[/tex]

[tex]T_{500} = -1976[/tex]

Hence, the 500th term is -1976.

Step-by-step explanation:

Let's narrow this down, shall we?

It could not be A, because AB and AD are not the same length, AD is a longer line

It is B, because AC an AD seem to be equal lengths

It is C because of B!  They are of equal length meaning ACD is a equilateral triangle

it could not be D because it appears to be a scalene triangle and have left as a longer side

It is E because CDE is a isosceles triangle

Answer:

x = 3

Step-by-step explanation:

Given

2(x - 4) = 7 - 3x ← distribute parenthesis on left side

2x - 8 = 7 - 3x ( add 3x to both sides )

5x - 8 = 7 ( add 8 to both sides )

5x = 15 ( divide both sides by 5 )

Answer:

The coordinates of point P are [tex]\left(\dfrac{-1}{10},\dfrac{-37}{10}\right)[/tex]

Step-by-step explanation:

The Coordinates of point A are (-4,-7), and the coordinates of point B are (9,4).

Let us assume that the coordinates of point [tex]\dfrac{3}{10}[/tex] of the way from A to B are P(x,y).

Now,

Applying the section formula,

[tex]x=\dfrac{3 \times 9+7 \times -4}{3+7}\\x=\dfrac{27 -28}{10}\\x=\dfrac{-1}{10}[/tex]

[tex]y=\dfrac{3 \times 4+7 \times -7}{3+7}\\y=\dfrac{12 -49}{10}\\y=\dfrac{-37}{10}[/tex]

Therefore, the coordinates of point P are [tex]\left(\dfrac{-1}{10},\dfrac{-37}{10}\right)[/tex]
