Express each logarithm in terms of In 2 and In 5.

Sladkaya [172]

Answer:

$5ln2-3ln5$

$2ln5-ln2$

Step-by-step explanation:

∵ $32=2^{5}$

∵ $125=5^{3}$

∵ $ln\frac{32}{125}=ln\frac{2^{5}}{5^{3}}$

∴ $ln2^{5}-ln5^{3}=5ln2-3ln5$

∵ $12.5=\frac{125}{10}=\frac{25}{2}=\frac{5^{2}}{2}$

∴ $ln12.5=ln\frac{5^{2}}{2}$

∴ $ln5^{2}-ln2=2ln5-ln2$

Answer:

First part = 2.

Time to land = 6 seconds.

Step-by-step explanation:

The object is at h = 0 when it land so

-5x^2 + 20x + 60 = 0

-5(x^2 - 4x) = -60

-5[(x - 2)^2 - 4] = -60

(x - 2)^2 - 4 = -60/-5 = 12

(x - 2)^2 = 16.

Solving the above:

Take the square root of both sides:

x - 2 = 4

x = 2 + 4

x = 6 seconds
