Mathematics
1 answer:
nordsb [41]3 years ago
7 0

Answer:

<h2>(2)</h2>

Step-by-step explanation:

Because

x^2-16=x^2-4^2=(x-4)(x+4)  not  =(x-4)(x-4)

This follows from the formula a^2-b^2=(a-b)(a+b)

Estimate the time it would take you to drive 361 miles at 42 miles per hour. Round to the nearest hour.
polet [3.4K]

Answer:

It would take you 9 hours

Step-by-step explanation:

Speed (s) = Distance (d) / Time (t)

given that; Speed = 42 miles/hour

                 Distance = 361 miles

42 miles/hour = 361 miles / Time (t)

Time (t) * 42 miles/hour = 361 miles

Time (t) = 361 miles / 42 miles/hour

Time (t) = 8.59 hours

             ≈ 9 hours (to the nearest hour)

the function g(x) Is the graph below resulted from shifting the graph of f(x) down 2 units. If f’(2)=8, what is g’(2)?
Sauron [17]

We know that the graph of g(x) is the result of a shift of 2 units down from f(x).

Then, f(x) and g(x) are related by:

g(x)=f(x)-2

Taking the derivative:

g^{\prime}(x)=f^{\prime}(x)

This is because the derivative of a constant number is 0. Finally, evaluating at x = 2:

\begin{gathered} g^{\prime}(2)=f^{\prime}(2) \\  \\ \therefore g^{\prime}(2)=8 \end{gathered}

Calculate the finance charge and new balance using the previous balance method. Previous balance = $179.32 Annual rate = 16% Fin
garik1379 [7]
Annual Rate = 16% = 16/100 = 0.16
Monthly Rate = (annual rate)/12
Monthly Rate = (0.16)/12
Monthly Rate = 0.01333 ... this is approximate

Finance Charge = (Monthly Rate)*(Previous Balance)
Finance Charge = (0.01333)*(179.32)
Finance Charge = 2.3903356
Finance Charge = 2.39

The purchases and payments do not factor in the finance charge since they are made during this current billing cycle. The previous balance method only looks at the balance at the end of the previous cycle. 

Once the finance charge is calculated, we add on the new purchases and the finance charge to the old balance. We also subtract off the payments/credits. Doing all this calculates the new balance for this billing cycle. 

New Balance = (Old balance) + (Purchases) + (Finance Charge) - (Payment)
New Balance = 179.32 + 117.42 + 2.39 - 85
New Balance = 214.13

In summary, 
Finance Charge = $2.39
New Balance = $214.13
