anygoal [31]

Answer:

2\times 15-6 = 24\ below\ sea\ level

Step-by-step explanation:

Given that:

Distance traveled by seal to catch the fish = 15 below sea level

Sea lion wanted to catch a larger fish so sea lion dove 6 feet lesser than two time the distance that the seal traveled.

To find:

The expression to represent the position of the sea lion in the sea.

Solution:

If the distance traveled by seal is represented by D then as per the question statement:

Twice of D = 2\times D

6 lesser than twice of D = 2\times D - 6

Now, putting the value of D = 15

Therefore, the expression to represent the sea lion's position w.r.to sea level.

2\times 15-6\\ = 24\ below\ sea\ level

Ray Of Light [21]
\bf recall\\\\
log_{{  a}}{{  b}}=y \iff {{  a}}^y={{  b}}\qquad\qquad 
{{  a}}^y={{  b}}\iff log_{{  a}}{{  b}}=y \\\\
-----------------------------\\\\
thus\qquad 
\begin{array}{cc|llll}
x&y&5^y=x\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
25&2&5^2=25\\
125&3&5^3=125\\
625&4&5^4=625\\
\end{array}
\\\\\\
\textit{so hmmm what would that be in log notation? }\  5^y=x \iff \boxed{?}

Suppose you buy a phone for $200 and its value depreciates linearly. If the phone is worth $115 after four years, then what is t
vredina [299]

Answer:

$72.5

Step-by-step explanation:

  • Initial value = $200
  • Depreciated value after 4 years = $115

<u>Since depreciation rate is linear, then:</u>

  • 200 - 4x = 115
  • 4x = 200 - 115
  • 4x = 85
  • x = 85/4
  • x = 21.25

<u>Value after 6 years:</u>

  • 200 - 6*21.25 = 200 - 127.5 = $72.5
