Answer:
The question is incomplete, the complete question is "Changing Bases to Evaluate Logarithms in Exercise, use the change-of-base formula and a calculator to evaluate the logarithm. See Example 9. .
Step-by-step explanation:
From the general properties or laws of logarithm, we have the
where both log are now express in the natural logarithm base.
i.e
hence we can express our .
the value of ln7 is 1.9459 and ln4 is 1.3863
Hence .
Answer:
<h2>4773 peoples.</h2>Step-by-step explanation:
Given the number of people d, in thousands applying for medical benefits per week in a particular city c modeled by the equation d(t)=2.5 sin(0.76t+0.3)+3.8 where t is the time in years, the maximum number of people tat will apply will occur at d(t)/dt = 0
Differentiating the function given with respect to t, we will have;
First we need to know that differential of any constant is zero.
If then;
To know the maximum number of people in thousands that apply for benefits per year in the city, we wil substitute the value of t = 29.75 into the modeled equation
Since d is in thousands, the maximum number of people in thousands will be 4.7732*1000 = 4773.2 which is approximately 4773 peoples.
