Expanding logarithmic Expression In Exercise,Use the properties of logarithms to rewrite the expression as a sum,difference,or m

Dmitry_Shevchenko [17]

Answer:

$\ln{(z)}+2\ln{(z-1)}$

Step-by-step explanation:

$\ln{(z(z-1)^2)}$

we know that

$\ln{ab} = \ln{a}+\ln{b}$

$\ln{(z)}+\ln{(z-1)^2}$

we also know that:

$\ln{a^b} = b\ln{a}$

$\ln{(z)}+2\ln{(z-1)}$

and this is our logarithmic expression rewritten!

The formula for the area of a triangle is A=12bh. Solve this equation for b.

aksik [14]

Step-by-step explanation:

Hey there!

Given;

[A = 1/2b*h]

Divide both sides by 'h'.

A/h = 1/2(b*h/h) [ on right side'h' gets cancelled].

Multiply '2' and 'A'.

A*2/h = b

b = 2A/h.

Hope it helps...

What the answer and how did you get it

Let x = the cost of the student discount card.

x + the cost of the passes = 29.50

x + 15(1.50) = 29.50

x + 22.50 = 29.50

Subtract 22.50 on both sides to isolate the variable x.

x = 29.50 - 22.50

x = 7

The student discount card is $7.

Element X decays radioactively with a half life of 6 minutes. If there are 790 grams of Element X, how long, to the nearest tent

frosja888 [35]

Answer:

It takes 27 minutes for the element to decay to 35 grams

Step-by-step explanation:

Given:

Initial amount = 790 grams

Final amount = 35 grams

Half life = 6 minutes

To find:

Time taken for the element to reduce into 35 grams = ?

Solutions

Time taken = $half life \times \frac{ log(\frac{ initial amount}{final amount})}{log(2)}$

On substituting the values given, Time taken

= $6 \times \frac{log(\frac{790}{35})}{log(2)}$

= $6 \times \frac{log(22.57)}{log(2)}$

= $6 \times 4.496$

= 26.97

= 27 minutes
