Answer:
1) c 2)c 3)b
Step-by-step explanation:
The answer would be C. We know that d is equal to the initial depth of a lake. The two given initial depths are 58 feet and 53 feet, so we know that one of the equations must be either d=58 or d=53. Because there only C has either one of those, d=58, we know that it must be the answer.
To find the other equation, it is just a linear function for the other lake. The y-intercept, or initial value, is 53, so in the equation y=mx+b, it is the b value. The slope, or m value, is 3 feet, so you have y=d=3x+53.
Answer:
<h2>x = 3.1</h2>
Step-by-step explanation:
<h3>

</h3>
<u>To solve first take logarithm to both sides</u>
That's
<h3>

</h3><h3 /><h3>

</h3>
But
<h3>

</h3>
So we have

<u>Write 1200 as a number with the factor 100</u>
That's
1200 = 100 × 12
So we have
<h3>

</h3>
<u>Using the rules of logarithms</u>
That's
<h3>

</h3>
Rewrite the expression
That's
<h3>

</h3><h3 /><h3>

</h3><h3>

</h3><h3>

</h3><h3 /><h3>

</h3>
x = 3.079
So we have the final answer as
<h3>x = 3.1 to one decimal place</h3>
Hope this helps you
A is correct because the f represents the lilies and then you add the 15 because that is how much roses there are going to be. Lastly just multiply the ten that will give you the answer
