The answer is B. 4

Rewrite the logarithmic equations using exponential equation

x- 3 / 2 = 1 / 8

The above equation may be rewritten as

x - 3 / 2 = 1 / 23 = 2-3

(√x)-3 = 2-3

The above equation gives

√x = 2 or x = 4

Given that a, b and c are positive integers, and abc=210, what is least possible sum for a+b+c

Vesnalui [34]

Answer:

The least possible sum for a+b+c is 18.

Step-by-step explanation:

As given a,b and c are positive integers and abc = 210

So, let us consider some situation in which the product abc = 20

If a, b and c are 5, 6 and 7 then

abc = 210 & a+b+c = 18

If a, b and c are 3, 7 and 10 then

abc = 210 & a+b+c = 20

If a, b and c are 7, 15 and 2 then

abc = 24 & a+b+c = 24

If a, b and c are 2, 5 and 21 then

abc = 210 & a+b+c = 28

From all of the above situation the least sum is 18 when a, b and c are 5, 6 and 7 respectively.

Help I don't know how to do this<br>

Answer:

P(t) = 282.2(1.009)^t

Step-by-step explanation:

Look at the attached image.

Hope you can read my handwriting. the image cut off the right side, b = 1.009213324... but question asks to round to nearest thousandth so it's 1.009

For the second part just use the equation to find P when t = -1 and see if P is less than (underpredicts) the number from the question or greater than (overpredicts) the number. I haven't calculated it but I think it will be smaller and thus underpredicts just from looking at the numbers when t = -1

After checking that conditions are met, you perform a significance test of 0:=1 versus :≠1 . You obtain a -value of 0.022.
