Which logarithmic equation is equivalent to the exponential equation below? E^a=35

oee [108]

Answer:

a = ln 35

Step-by-step explanation:

Given e^a = 35, take the natural log of both sides, obtaining:

ln e^a = ln 35. Recall that ln e^x = x, which means that ln e^a = a.

Then a = ln 35.

The amount ofmoney is in the ratio 8:3 if the first amount is 9.92 what is the second amount?

BARSIC [14]

Answer:

The second amount is 3.72

Step-by-step explanation:

Given

$First : Second = 8 : 3$

$First = 9.92$

Required

Find Second

$First : Second = 8 : 3$

Substitute 9.92 for First

$9.92: Second = 8 : 3$

Express as fraction

$\frac{Second}{9.92} = \frac{3}{8}$

Multiply both sides by 9.92

$9.92 * \frac{Second}{9.92} = \frac{3}{8}*9.92$

$Second = \frac{3}{8}*9.92$

$Second = 3.72$
