Write an equivalent exponential equation for the following three problems.

Naily [24]

Answer with step-by-step explanation:

We are given three different expressions and we are to write an equivalent exponential equation for them.

We know that the standard form of a logarithmic expression is given by:

$y = log_a ( x )$ which is equivalent to the exponential form $x = a ^ y$ .

1. $log _ {10} (0.1) = -1$ ---> $10^{-1}=0.1$

2. $log _ {3} 9 = 2$ ---> $3^2=9$

3. $log _ 5 ( \frac { 1 } { \sqrt { 5 } } ) = -\frac { 1 } { 2 }$ ---> $5^{-\frac{1}{2} }=\frac{1}{\sqrt{5} }$

The diagram shows the ratio of trees Maeve plants to the trees she harvests.

AnnZ [28]

Answer:

WEDNESDAY: 45 planted.

THURSDAY: 22 Harvested.

Step-by-step explanation:

Based on the information given in the problem, Maeve plants 5 trees for every 2 tree she harvests. Then the ratio can be expressed as following:

$5:2$ or $\frac{5}{2}$

Then, you can complete the values in the table as you can see below:

WEDNESDAY

$\frac{5}{2}=\frac{planted}{18}\\\\planted=\frac{18*5}{2}\\\\planted=45$

THURDAY

$\frac{5}{2}=\frac{55}{harvested}\\\\(harvested)(\frac{5}{2})=55\\\\harvested=\frac{55*2}{5}\\\\harvested=22$
