Answer:
see below
Step-by-step explanation:
90° clockwise rotation makes the transformation ...
(x, y) ⇒ (y, -x)
Your points are transformed to ...
- (-5, -1) ⇒ (-1, 5)
- (-3, -2) ⇒ (-2, 3)
- (-3, 2) ⇒ (2, 3)
For this problem, we use the formula for
radioactive decay which is expressed as follows:<span>
An = Aoe^-kt
where An is the amount left after time t, Ao is
the initial amount and k is a constant.
We calculate as follows:
An = 10 g</span>
<span>Ao = 40 g
k = 0.00043
An = Aoe^-kt
10 = 40e^-0.00043(t)
<span>t = 3223.94 years</span></span>
Answer:
B)
Step-by-step explanation:
The y axis is distance from home, so she can't start at (0,0), because that would imply that Jamie started at home. Thus, it has to be B or C. However, C never includes a section of the graph increasing, which is necessary to represent Jamie going further from home (back to school to get her book) before returning home, at y=0. Therefore, the answer has to be B)
