Answer:

$3.4*10^{1}$

Step-by-step explanation:

When multiplying you use the number with least amount of significant figures in it since both 0.00045 and 0.0015 have two significant figures in them our final answer will have two significant figures in it. So the to solve and express in scientific notation we simply multiply:

(0.00045)(500,000)

0.0015 = .3375 but in scientific notation to two significant figures we write:

$3.4*10^{1}$

<h3>What is a function?</h3>

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

Given series is as follows:-

-5.5, -4.75, -4, -3.25, ...

When we use the function:-

f(n) = - 6.25 + 0.75n

f(1) = -6.25 + 0.75 x 1 = -5.5

f(2) = -6.25 + 0.75 x 2 = -4.75

f(3) = -6.25 + 0.75 x 2.25 = -4

Therefore the correct answer is option B which is the function will be

f(n) = -6.25+0.75n.
