Answer: Choice C. p = 250(0.79)^t
Work Shown:
p = a*b^t
p = a*(1+r)^t
p = 250*(1+(-0.21))^t
p = 250(0.79)^t
Note that r = -0.21 is negative to indicate we have exponential decay.
I believe it would be 6 due to the radius being a half of the actual circumfrence
Symmetry means that one half of the distribution is a mirror image of the other half. For example, the normal distribution is a symmetric distribution with no skew. The tails are exactly the same
its D
4g/cm^3
D = M/V
100g/25cm^3 = 4g/cm^3
Answer:
(x +9.3)^2 +(y -4.1)^2 = 13
Step-by-step explanation:
The standard form equation of a circle centered at (h, k) with radius r is ...
(x -h)^2 +(y -k)^2 = r^2
Putting your numbers into this form gives ...
(x -(-9.3))^2 +(y -4.1)^2 = (√13)^2
(x +9.3)^2 +(y -4.1)^2 = 13
