Answer:(c)
Step-by-step explanation:
Given
The initial value of Adam's model is ![A_o=\$550](https://tex.z-dn.net/?f=A_o%3D%5C%24550)
the value increases exponentially with the rate of ![r\%](https://tex.z-dn.net/?f=r%5C%25)
Time period ![t=5\ years](https://tex.z-dn.net/?f=t%3D5%5C%20years)
Final amount ![A=\$736](https://tex.z-dn.net/?f=A%3D%5C%24736)
Exponential growth is given by
![\Rightarrow A=A_o(1+r)^t](https://tex.z-dn.net/?f=%5CRightarrow%20A%3DA_o%281%2Br%29%5Et)
Putting values
![\Rightarrow 736=550(1+r)^5\\\\\Rightarrow (1+r)^5=1.338](https://tex.z-dn.net/?f=%5CRightarrow%20736%3D550%281%2Br%29%5E5%5C%5C%5C%5C%5CRightarrow%20%281%2Br%29%5E5%3D1.338)
![\Rightarrow 1+r=1.05999\\\Rightarrow r=0.05999\ or\ 5.99\%\approx 6\%](https://tex.z-dn.net/?f=%5CRightarrow%201%2Br%3D1.05999%5C%5C%5CRightarrow%20r%3D0.05999%5C%20or%5C%205.99%5C%25%5Capprox%206%5C%25)
Option (c) is correct

Answer:
The answer is she sold 20 labradorite crytals and 3 galena crystals.
Step-by-step explanation:
First you times 20 x 20 and get 400 and then times 13 x 3 and get 39 and 400 plus 39 equals $439.
Answer:
87.92in³
Step-by-step explanation:
Volume of cylinder formula:
![V = \pi r^{2} h](https://tex.z-dn.net/?f=V%20%3D%20%5Cpi%20r%5E%7B2%7D%20h)
Plug in the values using 3.14 for pi:
V = 3.14(2)^2(7)
V = 87.92in³
Y = -2x + 8 = x - 4
x + 2x = 8 + 4
3x = 12
x = 4
y = -2(4) + 8 = -8 + 8 = 0
Solution is (4, 0)
