Answer:
Using the attached formula:
exp = log (total/principal) / n * years
exp = log (10,000 / 7,500) / 12 * 20
exp = log (1.3333333333) / 240
exp = 0.1249387366 / 240
exp = 0.000520578069166667
rate = (10^exp -1) * n
rate = (10^0.000520578069166667 -1) * n
rate = 1.00119939400018 -1 * n
rate = .00119939400018 * 12
rate = 0.014392728
OR rate = 1.4392728 % Compounded Monthly
OR rate = 1.448805264762% Compounded Annually
Step-by-step explanation:
Carl is right because simplifying it gets us:
The only point outside of the line is (2, 0)
In order to find if a point is outside, inside or on the line, you simply have to put the number into the equation. If the result is both sides are equal, then it is on the line. If the left side is bigger than the right side, then it is outside of the line. If the right side is bigger than the left, then it is inside of the line. So lets plug in and see where (2, 0) falls.
(x - 2)^2 + (y + 3)^2 = 4
(2 - 2)^2 + (0 + 3)^2 = 4
0^2 + 3^2 = 4
0 + 9 = 4
9 = 4
Since the left side is bigger than the right, we know it is outside of the line.
Pythagorean theorem
for a right triangle with legs legnth a and b and hytponuse c
a^2+b^2=c^2
the legnht of th eladder is the hypotnuse
the 3 feet is bottom leg
height is other leg
10=c
3=a
b=?
3^2+b^2=10^2
9+b^2=100
minus 9 both sides
b^2=91
sqrt both sides
b=√91
aprox
b=9.53939
answer is √91 feet or aprox 9.53939
