Use explicit formula to find the 10th of each geometric sequence

Mathematics
1 answer:
Sindrei [870]3 years ago
3 0

Answer:

1. 1*9^(10-1) = 387,420,489

2.2*4^(10-1) = 524,288

Step-by-step explanation:

The explicit formula for a geometric sequence is a1 * r^n-1

Where a1 is your first term, r is your ratio, and n is the amount of terms you want in the sequence

To solve for the 10th number in the sequence, we simply plug 10 in for n.

Hope this helps

Find mzC.<br> B<br> (2x – 12)<br> (9x – 26)<br> (4x + 43)
MrMuchimi

Answer:

m<C = 119°

Step-by-step explanation:

Create an equation to find the value of x.

(9x - 26)° = (2x - 12)° + (4x + 43)° (exterior angle theorem of a ∆)

Solve for x

9x - 26 = 2x - 12 + 4x + 43

Add like terms

9x - 26 = 6x + 31

9x - 6x = 26 + 31

3x = 57

Divide both sides by 3

x = 19

✔️m<C = 4x + 43

Plug in the value of x

m<C = 4(19) + 43

m<C = 76 + 43

m<C = 119°

Five quarts of oil and an oil filter cost $20.35. However, with a coupon, these items may be purchased for $4.43 less. What is t
kupik [55]
Hey there :)

5 quarts of oil and an oil filter - $20.35
With couple - $4.43 less
Final cost?

We subtract 4.43 from $20.35
Why? That's the expected amount [ without a coupon ]

 20.35
-  4.43
  15.92

The final cost will be $15.92

Three consecutive integers have a sum of 48 find the integers?
zavuch27 [327]

The sum of three consecutive integers is three times the middle one: if we call the middle one x, the three numbers are

x-1,\ x,\ x+1

So, their sum is x-1+x+x+1 = 3x

Which is three times the middle one.

So, if the sum of three consecutive intergers is 48, the middle one must be 48/3 = 16.

So, the three numbers are 15, 16 and 17
