jenny borrowed $500 for 5 years at 4% interest compounded annually. what is the total amount she will have paid when she pays of

alexdok [17]

Use the formula for compound interest,

$A=P(1+ \frac{r}{n})^{nt}$

Where P is the starting amount (500$), r is the rate of interest (0.04), n is the number of times the interest is compounded per unit (1 per year), and t is the amount of time it is compounded (5 years).

Now, plug it into the formula:

$A=500(1+ \frac{0.04}{1})^{5}$

Do the math, and your answer is she must pay <span>608.32$ when she pays her debts.</span>

Find the geometric mean of 5 and 7

dsp73

Answer:

$\sqrt{35}$

Step-by-step explanation:

A geometric mean is just $\sqrt[n]{term one * term two * term three * etc.}$ , where n is the number of terms.

i.e. Geometric mean of 5, 6, 7: there are three values, so the mean is $\sqrt[3]{5*6*7}$

Find which one is f f' f"

Olegator [25]

f - green (A)

f' - red (B)

f'' - blue (C)

The graph of f attains local extrema at the same points that f' = 0. There's evidence of this at x = 0 and between x = 3 and x = 3.5. (At both points, curve A attains a maximum, while curve B crosses the x-axis.)

Similarly, the graph of f' attains local extrema at the same points that f'' = 0. This is seen between x = 1.5 and x = 2. (B has a max, C crosses axis)

Also, the graph of A is continuous at x = 1.5 but exhibits a sharp turn, so at this point f is not differentiable and the graph of f' (and subsequently f'') is not continuous.
