The amount on interest he earned is $5116.8
Step-by-step explanation:
Given,
Principal(P) = $16400
Rate of interest(R) = 3.9%
Time(T) = 8 years
To find the interest
Formula
Simple interest = 
Hence,
The interest =$ 
= $5116.80
Answer:
y=3
Step-by-step explanation:
it says that y is the inverse of x so if x=3 and y=8, so if x=8 than y must equal 3
OK, let's try with no figure. We have an isosceles triangle sides s,s, and b.
Opposite b is angle t.
Draw the altitude h to bisect t. We have two right triangles, legs b/2 and h, hypotenuse s. The angle opposite b/2 is t/2 so
sin(t/2) = (b/2)/s = b/2s
So we arrived at the first part,
b = 2s sin(t/2)
The area of a triangle with sides s,s and included angle t is
A = (1/2) s² sin t
X^2 - 7x + 12 = 0
x^2 - 4x - 3x + 12 = 0
x (x - 4) -3 ( x - 4) = 0
(x - 4) (x - 3) = 0
x = 3 , 4
Check the answer by plugging in 3 and 4 for x, if the equation equals zero then you have your answer.
