We'll say principal = 100 and total = 200
a) exp = log(total / principal) / (n* years)
where "n" is the number of compounding periods per year
exp = log (200 / 100) / (4*6)
exp = log (2) / (24)
exp = 0.30102999566 / 24
exp =
<span>
<span>
<span>
0.0125429165
</span>
</span>
</span>
b) rate = (10^exp -1) * n
rate = (10^<span>0.0125429165 -1) * n
</span>rate =
<span>
<span>
<span>
(1.0293022367
</span>
</span>
</span>
-1) * n
rate = <span>.0293022367 * 4
</span>rate =
<span>
<span>
<span>
0.1172089468
</span>
</span>
</span>
rate = 11.<span>72089468 %
</span>See? It's just that simple. LOL

Answer:
Step-by-step explanation:
The vertex can be located most easily by completing the square of
f(x) = -X^2 - 2x - 1 (which is equivalent to -(x^2 + 2x + 1). The latter expression can be rewritten as -(x + 1)^2, which indicates that the x-coordinate of the vertex is -1. The corresponding y-value is 0. Vertex is at (-1, 0).
The function is increasing for x < -1 and decreasing for x > -1.
The domain of the function is "all real numbers."
The range is (-infinity, 0)
Answer:
Width is 10ft and length is 6ft.
Step-by-step explanation:
The area of a shape is the amount inside a shape. It is found using multiplication or A = l*w. Since the width is w and the length is 4ft less than its width or w - 4, use these expressions in the area formula to find their amount.
Subtract 60 from both sides and factor the quadratic to solve for w.
Set each factor equal to 0 and solve.
w - 10 = 0 so w = 10
w + 6 = 0 so w = -6.
Since w represents a length or distance it cannot be negative, this means the width is 10. The length which is w - 4ft is 10 -4 = 6. The length is 6 ft.
