Answer:
Y= 3/5-4
Step-by-step explanation:
What is slope-intercept form? Slope intercept form is an equation for graphing. It is y=mx+b. The "m" stands for the slope, or how much coordinates it takes to move to the next point. The "b" stands for the y-intercept, or where the line is perfectly on the y-line.
Step One: The first part of the equation is the slope, so let's figure that out. Since this one a graph, it is easy to tell the slope. The points are nicely marked, so we don't have to guess which points are visible. We are going up 3 jumps and then across 5 jumps. The slope is always "rise/run" where the "rise" is the y and "run" is x. So, the slope is 3/5x.
Step Two: For the last part, we need to know the y-intercept. It is clearly shown on the graph: -4. Because it is negative, we remove the plus sign because a plus with a negative is subtraction.
Step Three: We can combine both parts and that is the answer: y=3/5x-4.

Thus, The correct option is B).
Expression A is equivalent
Answer:
2.5mg
Step-by-step explanation:
Since the half-life for the radioactive material is 3 hours, Therefore it will undergone two times of half-life process.
The first 3 hours 10mg will be decreased into 5mg. The final 3 hrs, it will decreased from 5mg to 2.5mg
Yo sup??
We have to apply trigonometry ie cosine formula
cos44=RS/RQ
RS=RQ*cos44
=7.2
Hope this helps
