What's the sum & classification of 3/10 and square root of 10? 3.31227766,irrational 3.31227766,rational 18.16227766,irrational 18.16227766,rational

3.46227766; irrational

Step-by-step explanation:

The sum of 3/10 and √10 can be written mathematically as:

3/10 + √10

Taking the LCM which is 10

3/10 + √10 = 0.3 + 3.16227766

= 3.46227766

Since we cannot express the resulting value as a ratio of two integers, therefore the value is classified as an irrational number.

the answer is b

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
