Answer:
matter is any substance that has mass and takes up space by having volume
Step-by-step explanation:
Expression: 2.8 * 10⁷ / 1.4 * 10³
= 2 * 10⁷⁻³
= 2 * 10⁴
In short, Your Answer would be: Option A
Hope this helps!
answer: 360
Given:
Machine A Candy Packing
x(minutes) y(candies)
5 600
10 1200
15 1800
20 2400
Machine B : y = 150x
Find number of candies packed in 12 minutes.
Machine A : 600/5mins = 120 candies per minute
120 * 12 minutes = 1,440 candies
Machine B : y = 150x ⇒ y = 150(12) ⇒ y = 1,800
Machine B: 1,800
Machine A: 1,440
Difference 360
Machine B packed 360 more candies than Machine A in 12 minutes.
I'm guessing you're given the function , and you're asked to find the inverse function . To do this, swap and , then solve for :
so that the inverse function is
Just to verify:
But in case you're actually only interested in computing the square root, first we note that (the real-valued square root) is only defined as long as . So is defined as long as , or , or equivalently . Under this condition, we could write
We can simplify this further, but we have to be careful. Suppose . Then . But we get the same result if , since . There are two possible values of that given the same value of , so to capture both of them, we take , the absolute value of . Then
We can't simplify the square root term further than this.
