Write both sides as powers of e:

\ln(x+4)=-1\implies e^{\ln(x+4)}=e^{-1}\implies x+4=e^{-1}

since b^{\log_ba}=a. Then

x=e^{-1}-4\approx-3.63

7. Find the amount of money accumulated if you invest $10,000 at 3% interest compounded continuously for 2 years. Round your
IrinaK [193]

Answer:

$10618.37

Step-by-step explanation:

Use the formula for compound interest:

P(t) = P_0e^(rt)

You can look the formula up online to find what each variable represents.

First, our principal amount (P) is 10,000. Our interest rate (r) is 3% and our time (t) is 2. Substitute these into the equations in each variables' place. The equation will look like this:

P(t) = 10,000e^(0.03x2)

P(t) = 10,000e^(0.06)

Note that e is approximately 2.7183 .

Using your calculator, now simply find P(t).

You should get 10618.36972 as your answer. Round that to the nearest cent to get $10618.37 .

The volume of a landfill doubles every three years. Write an exponential function to represent this.
stellarik [79]
The equation would be: V = A2^(Y/3)

The basic form of an exponential equation is y = ab^x.

The a is the starting amount. In this problem, we don't know that, so we just leave it as a.

The b is the rate. In this case, we are doubling the volume so we times it by 2.

The x is the amount of years. Since it is every 3 years, we can divide the x by 3.

4th grade math. Help?!
viva [34]

Answer: Well... does it give you the approximate length or actual length of the butterfly? If so, you would take that length and multiply it by 5. That would give you the length of the 5 butterfly lined up together.

If it does not give you the approximate length or actual length, look up the length on google.  (Google Answer- Size: 2.5" - 4.0" range.)

Take that and multiply it by five to get the length of the 5 butterflies.
