Let f(x)=−x√3 . What is the average rate of change of f(x) from 8 to 64?
Fed [463]

Average rate of change of the function: -\sqrt{3}

Step-by-step explanation:

The average rate of change of a function f(x) can be calculated as:

r=\frac{f(x_2)-f(x_1)}{x_2-x_1}

where:

x_1, x_2 are the x-values of the interval taken into account to evaluate the rate of change of the function

f(x_1),f(x_2) are the values of the function at those points

In this problem, we have:

x_1=8\\x_2=64

The function is f(x)=-x\sqrt{3}, so

f(x_1)=f(8)=-8\sqrt{3}\\f(x_2)=f(64)=-64\sqrt{3}

So, the average rate of change in this interval is:

r=\frac{-64\sqrt{3}-(-8\sqrt{3})}{64-8}=\frac{-56\sqrt{3}}{56}=-\sqrt{3}

larisa [96]
Compute the ending balance of the opening balance for the first day then add deposited amount after that compute the balance
The formula is
A=p (1+r/k)^kt
A future value
P present value
R interest rate
K compounded daily 365
T time in days x/365

To sum up kt =365×(1/365)=1 day
A=900×(1+0.021÷365)^(1)
A=900.0517808219... the balance before the amount deposited is added

Now add the amount deposited
900.0517808219+76.22
=976.2717808219

Calculate the balance using the same formula
A=976.2717808219×(1+0.021÷365)^(1)
A=976.33. ..answer

Hope it helps!
