Answer:

a=3

Step-by-step explanation:

3a-4=5

put the 4 on the same side as the 5 and switch it from - to +

Ex.  3a=5+4

now add the 5 and the 4

Ex.   3a=9

now isolate the variable (thats the letter) by dividing 3a by 3, then divide the 9 by 3 simultaneously

Ex.   3a/3=a  |  9/3=3

Then v

       a=3

(Lesson 31) The population of Jacksonville, Florida, was 736,000 in 2000 and was increasing at a rate of 1.49% each year. At
damaskus [11]

Answer:

Step-by-step explanation:

Population t years after 2000 = 736,000 × 1.0149^t

736,000 × 1.0149^t = 1,000,000

1.0149^t = 1,000,000/736,000 = 125/92

Take log base 1.0149 of both sides

t ≈ 20.7

Population exceeds a million in 2021

Evaluate each geometric series described<br> 1-4+16-64...., n=6
xz_007 [3.2K]

Answer:

- 819

Step-by-step explanation:

The sum to n terms of a geometric series is

S_{n} = \frac{a(r^n-1)}{r-1}

where a is the first term and r the common ratio

Here a = 1 and r = - 4 ÷ 1 = - 4, thus

S_{6} = \frac{1((-4)^6-1)}{-4-1} = \frac{4096-1}{-5} = \frac{4095}{-5} = - 819

The sum of rational number and an irrational number
Angelina_Jolie [31]

Answer:

The sum of a rational number and an irrational number is irrational." By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats.

Step-by-step explanation:

However, if the irrational parts of the numbers have a zero sum (cancel each other out), the sum will be rational. "The product of two irrational numbers is SOMETIMES irrational." Each time they assume the sum is rational; however, upon rearranging the terms of their equation, they get a contradiction (that an irrational number is equal to a rational number). Since the assumption that the sum of a rational and irrational number is rational leads to a contradiction, the sum must be irrational.
