Answer:
(5,0)=x1,y1
(0,3)=x2,y2
so the range will be x1-x2/
Answer:
it would be answer a

that's all i have
Answer:
B
Step-by-step explanation:
For the three rectangles:
30x17=510
30x10=300
30x21=630
REMEMBER: the formula for solving triangles are Area = 1/2 base x height
For the 2 triangles:
1/2x21x8 = 84
And since there are 2 triangles that are both the exact same, you do 84x2, which equals 168
Finally, you add all the numbers together:
510+300+630+168 = 1,608
Which looks like is letter B on your paper
The answer should be A. In order to solve these half-life problems, I encourage you to find an algebra calculator online, and plug in these numbers. The remaining grams goes in front, so 3.
The entire equation should look something like 3 = 15(1/2)^t/4.95
The 4.95 represents how long it takes before the sample halves, t is your answer, 1/2 represents the value halving every 4.95 hours, 15 is the initial sample size, and 3 is the end result that remains.
The overall answer should be about 11.5 hours, as per an algebra calculator.
Hope this helps solve any other similar problems
