Answer:
Gold
Step-by-step explanation:
<em>Casandra finds a treasure chest packed with metallic coins. The chest has a volume of 0.25 cubic meters. The coins have a combined mass of 4825 kg. Hoping to find gold, she calculates the density to determine the metal of the coins.</em>
<em>What kind of metal are the coins made of?</em>
<em>Bronze (8700 kg per cubic meter)</em>
<em>Silver (10500 kg per cubic meter)</em>
<em>Lead (11300 kg per cubic meter)</em>
<em>Gold (19300 kg per cubic meter)</em>
<em />
Density is mass per volume:
D = M / V
D = (4825 kg) / (0.25 m³)
D = 19,300 kg/m³
The coins must be made of gold.
Answer:
2x (x - 4)
Step-by-step explanation:
Answer:
The function f(x) was translated right 3 units and up 2 units.
Step-by-step explanation:
F(x)=(2/3)^x
If we move it right for 3 units, we get
f(x)= (2/3)^(x-3)
If we move up 2 units , we get
g(x)= (2/3)^(x-3) +2
