Answer:
Option d. the initial amount of money placed in the savings account
Step-by-step explanation:
we have
![f(x)=3,005(1+0.03)^{x}](https://tex.z-dn.net/?f=f%28x%29%3D3%2C005%281%2B0.03%29%5E%7Bx%7D)
This is a exponential function of the form
![f(x)=a(1+r)^{x}](https://tex.z-dn.net/?f=f%28x%29%3Da%281%2Br%29%5E%7Bx%7D)
where
a is the initial value
r is the growth rate
(1+r) is the base
x is the number of years
f(x) is the amount of money in a savings account
In this problem we have
a=$3,005
r=0.03=3%
(1+r)=1.03
therefore
3,005 represent the initial value ( the amount of money for the value of x equal to zero)
Answer:
The value of currents are
,
and
.
Step-by-step explanation:
The Ohm's law states that
![V=IR](https://tex.z-dn.net/?f=V%3DIR)
it is given that the V₁=3V and V₂=4V.
In a parallel circuit:
- Voltage is same in each component
- Sum of the currents equals to the total current that flows.
.... (1)
Equation for first loop is,
![V_1=4I_1+3I_2](https://tex.z-dn.net/?f=V_1%3D4I_1%2B3I_2)
..... (2)
Equation for second loop is,
![V_2=1I_3+3I_2](https://tex.z-dn.net/?f=V_2%3D1I_3%2B3I_2)
..... (3)
On solving (1), (2) and (3) we get
![I_1=0](https://tex.z-dn.net/?f=I_1%3D0)
![I_2=1](https://tex.z-dn.net/?f=I_2%3D1)
![I_3=1](https://tex.z-dn.net/?f=I_3%3D1)
Therefore the value of currents are
,
and
.
Answer:
ok so we can turn both of these into equations
Bob: 112.96 divided by 138=0.81855072463
so about 82 cents per mile
Carl: 142.78 divided by 209=0.68315789473
so about 68 cents per mile
so ya i am a little confused but heres what i got
Answer:36
Step-by-step explanation:
18×2= 36 because if each got halfed, each half would equal one sandwich so there would be 36 sandwiches
