Hello,
simplify the expression:
3 · 2x = 6x
the coefficient is a number that stands right before x: kx
then in our case:
kx=6x
so k=6 is the coefficient

Bye :-)

PIT_PIT [208]

Answer:

The total phone numbers, if the latter ABC is followed, will be 175.

Step-by-step explanation:

We are told that the digits will be in the form ABC and A can take values from 2 – 8, B from 5 – 9 and C from 5 – 9 as well.

This means:

A has 7 possible values (when you count the number of numbers between 2 and 8).

B has 5 possible values.

C has 5 possible values.

Therefore, the total phone numbers, if the latter ABC is followed, will be:

7 x 5 x 5 = 175.

I need help pleaseee
kumpel [21]

Answer: $7448

Step-by-step explanation:

Year 1: 1.218x

Year 2: 1.218(1.218x)

Year 3: 1.218(1.218(1.218x))

Year 4: 1.218(1.218(1.218(1.218x)))

Year 5: 1.218(1.218(1.218(1.218(1.218x))))

Year 6: 1.218(1.218(1.218(1.218(1.218(1.218x)))))

Year 7: 1.218(1.218(1.218(1.218(1.218(1.218(1.218x))))))

Year 8: 1.218(1.218(1.218(1.218(1.218(1.218(1.218(1.218x)))))))

Year 9: 1.218(1.218(1.218(1.218(1.218(1.218(1.218(1.218(1.218x))))))))

Year 10: 1.218(1.218(1.218(1.218(1.218(1.218(1.218(1.218(1.218(1.218x)))))))))

Year 11: x(1.218¹¹)

Year 12: x(1.218¹²) = 79,400

         

x(10.6602517) = 79,400

x = 79,400/10.6602517

x=7448.22939

x = $7448

Hope this helps!

Create three geometric sequences of your own (including one that is decreasing). Extend your sequences to include five terms. Th
Karo-lina-s [1.5K]

Answer:

a)  a_n=5\,\,(2)^{n-1}

b)  b_n=100\,\,(\frac{1}{2} )^{n-1}

c)  c_n=160\,\,(-\frac{1}{2} )^{n-1}

Step-by-step explanation:

a)  Geometric sequence with first term 5 and common ratio 2, where the nth term can be calculated via:

a_n=5\,\,(2)^{n-1}

The first five terms are: a_1=5;\,\,\,a_2=10;\,\,\,a_3=20; \,\,\,a_4=40;\,\,\,a_5=80

b) Geometric sequence with first term 100 and common ratio 1/2, where the nth term can be calculated via:

b_n=100\,\,(\frac{1}{2} )^{n-1}

The first five terms are: a_1=100;\,\,\,a_2=50;\,\,\,a_3=25; \,\,\,a_4=12.5;\,\,\,a_5=6.25

c)  Geometric sequence with first term 160 and common ratio -1/2, where the nth term can be calculated via:

c_n=160\,\,(-\frac{1}{2} )^{n-1}

The first five terms are: a_1=160;\,\,\,a_2=-80;\,\,\,a_3=40; \,\,\,a_4=-20;\,\,\,a_5=10
