Answer:

8

Step-by-step explanation:

Nth term of a geometric sequence is given as:

t_n = a r^{(n-1)} ...(1)

Plugging n = 9, a = 3 and r = 2 in the above equation, we find:

t_9 = (3) (2)^{9-1}

t_9 = (3) (2)^{8}... (2)

Comparing equations (1) & (2), we obtan:

(n - 1) = 8

Answer:

90 - 37 will give a solid 53

Step-by-step explanation:

the two sums of A to C to C to B so 22.9(C, B) and 14.1 (A, C)

and know that this angle is 90 degrees, my guess would be to subtract the to given numbers with degrees to earn the sum so 22.9 + 14.1 equals 37

now we add angle degrees and sum and subtract one another,

90 - 37

Is 3²+3³ equal to 3⁵? <br> ( yes, no ) the expressions (are, are not ) equal
Vera_Pavlovna [14]

Answer: <u>No</u> the expressions <u>are not</u> equal

Work Shown:

3² = 3*3 = 9

3³ = 3*3*3 = 27

3²+3³ = 9+27 = 36

3⁵ = 3*3*3*3*3 = 243

The 3²+3³ = 36 doesn't match up with 3⁵ = 243

Therefore, the two expressions are not equal.

valentinak56 [21]

Answer:

344 visitors

Step-by-step explanation:

Given that the relationship between the number of visitors to a museum(y) and the daily rainfall in mm(x) is defined as

y=14.1x+62.0

when the daily rainfall is 20 mm, the number of visitors

y = 14.1(20) + 62

= 282 + 62

= 344

It means that the expected number of visitors is 344 persons (to the nearest integer).
