Answer:
The first coin will be worth $137.16 more than the second coin.
Step-by-step explanation:
Interest formula = i = prt
For coin #1:
p = 1270
r = 0.061
t = 18
i = (1270)(0.061)(18)
The first coin will be worth $2664.46 after 18 years.
For coin #2:
p = 1270
r = 0.055
t = 18
i = (1270)(0.055)(18)
The second coin will be worth $2527.30 after 18 years.
Subtract the value of coin #2 from coin #1.
2664.46 - 2527.30 = 137.16
In conclusion, the first coin will be worth $137.16 more than the second coin after 18 years.
Answer:
m∠CAO=8º
m∠SAC=82º
Step-by-step explanation:
We know that m∠OAS is 90º because it is a radius to a tangent. This will be useful later.
OA=OB because they are both radii. If we draw a line from A to B, this makes an isosceles triangle ABO with a vertex angle of 32 because of the central angle theorem. This means that m∠OAB and m∠OBA are both 74º.
Isosceles triangle CAB is also formed with the construction of AB. Using the inscribed angle theorem, we can find ACB, which is 16º. Solve for the other angles and you get 82º. To find m∠CAO, subtract m∠OAB from m∠CAB, and this returns 8.
To find m∠SAC, subtract m∠CAO from m∠OAS, which is 90º-8º, and you get 82º.
