Answer: 220.5 ft^2
Step-by-step explanation:
You separate it into shapes and sum the area of those. I made a triangle 15 by 15, a rectangle 4 by 15, a smaller rectangle 4 by 10, and a triangle 4 by 4
Answer:
% Po lost = 100[1 - e^(-0.005t)] %; 73.0 g
Step-by-step explanation:
p(t) = 100e^(-0.005t)
Initial amount: p(0) = 100
Amount remaining: p(t) = 100e^(-0.005t)
Amount lost: p(0) – p(t) = 100 - 100e^(-0.005t) = 100[1 - e^(-0.005t)]
% of Po lost = amount lost/initial amount × 100 %
= [1 - e^(-0.005t)] × 100 % = 100[1 - e^(-0.005t)] %
p(63) = 100e^(-0.005 × 63) = 100e^(-0.315) = 100 × 0.730 = 73 g
The mass of polonium remaining after 63 days is 73 g.
Answer:
It would be the first option.
f(x) = -2 |x| + 1
If there were 4 pieces eaten, and 3/7 left, then there must have been 7 pices altogether and 3 are left.
Answer:
Below.
Step-by-step explanation:
The parabola will open to the right and will be symmetrical about y = 3.
The vertex is halfway between x = 1 and x = -7 making it at (-3, 3).
The p value is the distance between the vertex and the focus - here it is 1 - -3
= 4.
