Answer: 21 1/3 ft. tall

The first eight terms of the sequence are 27, 27, 39, 87, 117.378, 147.755, 178.132 and 208.509.

By (1) we have that [tex]a = 27 - A[/tex], and we simplify the system of equations as follows:

[tex](27-A)+d + A\cdot r = 27[/tex]

[tex]d + (r-1)\cdot A = 0[/tex] (2b)

[tex](27-A) +2\cdot d + A\cdot r^{2} = 39[/tex]

[tex]2\cdot d + (r^{2}-1)\cdot A = 12[/tex] (3b)

[tex](27-A) +3\cdot d + A\cdot r^{3} = 87[/tex]

[tex]3\cdot d + (r^{3}-1)\cdot A = 60[/tex] (4b)

By (2b), we simplify the system of equations once again:

[tex]2\cdot (1-r)\cdot A+(r^{2}-1)\cdot A = 12[/tex]

[tex][2\cdot (1-r)+(r^{2}-1)]\cdot A = 12[/tex] (3c)

[tex]3\cdot (1-r)\cdot A + (r^{3}-1)\cdot A = 60[/tex]

[tex][3\cdot (1-r) + (r^{3}-1)]\cdot A = 60[/tex] (4c)

And by equalising (3c) and (4c) we have an expression in terms of [tex]r[/tex]:

[tex]\frac{12}{[2\cdot (1-r)+(r^{2}-1)]} = \frac{60}{[3\cdot (1-r)+(r^{3}-1)]}[/tex]

[tex]12\cdot [3\cdot (1-r)+(r^{3}-1)] = 60\cdot [2\cdot (1-r) + (r^{2}-1)][/tex]

[tex]36\cdot (1-r) +12\cdot (r^{3}-1) = 120\cdot (1-r)+60\cdot (r^{2}-1)[/tex]

[tex]84\cdot (1-r) +60\cdot (r^{2}-1)-12\cdot (r^{3}-1) = 0[/tex]

[tex]84-84\cdot r +60\cdot r^{2}-60-12\cdot r^{3}-12 = 0[/tex]

[tex]-12\cdot r^{3}+60\cdot r^{2}-84\cdot r +2 = 0[/tex] (5)

The roots of this third order polynomial are: [tex]r_{1} \approx 0.0242[/tex], [tex]r_{2} = 2.488 + i\,0.831[/tex] and [tex]r_{3} \approx 2.488-i\,0.831[/tex]. Since [tex]r[/tex] must be a real number, then [tex]r \approx 0.0242[/tex].

By (4c) we have the value of [tex]A[/tex]:

[tex]A = \frac{60}{3\cdot (1-0.0242)+(0.0242^{3}-1)}[/tex]

[tex]A \approx 31.130[/tex]

By (2b) we find the value of [tex]d[/tex]:

[tex]d = (1-0.0242)\cdot 31.130[/tex]

[tex]d = 30.377[/tex]

And by (1) we find the value of [tex]a[/tex]:

[tex]a = 27-A[/tex]

[tex]a = 27-31.130[/tex]

[tex]a = -4.13[/tex]

The first eight terms are calculated below:

[tex]n_{1} = 27[/tex]

[tex]n_{2} = 27[/tex]

[tex]n_{3} = 39[/tex]

[tex]n_{4} = 87[/tex]

[tex]n_{5} = [-4.13 + 4\cdot (30.377)]+(31.130)\cdot (0.0242)^{4} = 117.378[/tex]

[tex]n_{6} = [-4.13+5\cdot (30.377)+(31.130)\cdot (0.0242)^{5}] = 147.755[/tex]

[tex]n_{7} = [-4.13+6\cdot (30.377)\cdot (31.130)\cdot (0.0242)^{6}] = 178.132[/tex]

[tex]n_{8} = [-4.13+7\cdot (30.377)\cdot (31.130)\cdot (0.0242)^{7}] = 208.509[/tex]

The first eight terms of the sequence are 27, 27, 39, 87, 117.378, 147.755, 178.132 and 208.509. [tex]\blacksquare[/tex]

The statement present typing mistakes and is poorly formatted. Correct form is shown below:

The first four terms of an arithmetic sequence are: [tex]a[/tex], [tex]a + d[/tex], [tex]a + 2\cdot d[/tex], [tex]a + 3d[/tex]. The first four terms of another sequence are: [tex]A[/tex], [tex]A\cdot r[/tex], [tex]A\cdot r^{2}[/tex], [tex]A\cdot r^{3}[/tex]. The eight terms satisfy:

[tex]a + A = 27[/tex] (1)

[tex](a+d)+A\cdot r = 27[/tex] (2)

[tex](a + 2\cdot d) + A\cdot r^{2} = 39[/tex] (3)

[tex](a + 3\cdot d) + A\cdot r^{3} = 87[/tex] (4)

By using the substitution [tex]a = 27-A[/tex], or otherwise, find the all eight terms.

Answer:

the answer is c

Step-by-step explanation:

Answer:

c ≥ 8

Step-by-step explanation:

1/4c − 1 + 1/4c ≥ 3

Step 1: Add 1/4 to 1/4, since they are on the same side of the equation

1/4 + 1/4c - 1 ≥ 3

1/4 + 1/4 = 1 + 1 / 4

= 2/4

= 1/2

Step 2: Put together the equation

1/2c - 1 ≥ 3

Step 3: Add 1 to both sides.

1/2c − 1 + 1 ≥ 3 + 1

1/2c ≥ 4

Step 4: Multiply both sides by 2.

2 × 1/2c ≥ 2 × 4

c ≥ 8

Step-by-step explanation:

Answer:

(C) 122/153

Step-by-step explanation:

Let x be the required fraction.

(-4/9) + x  =  6/17

Add both sides by 4/9

x  =  (6/17) + (4/9)  

 =  (54 + 68)/153

 =  122/153

Answer:

Step-by-step explanation:

Let's create an equation to solve for the variable x. Then, isolate the x by adding 4/9 to both sides. Lastly, simplify and solve for the x variable.

Looking at all the options, Option C is matching with our result.

Hence, Option C is correct.

The partial product method involves multiplying each digit of one number in turn with each digit of another where each digit keeps its place. (So ​​the 2 in 23 would actually be 20.) For example, 23 x 42 would become (20 x 40) + (20 x 2) + (3 x 40) + (3 x 2).
