Amount in compound interest = p(1 + r/t)^nt where p is the initial
deposit, r = rate, t = number of compunding in a period and n = period.
Here,
Amount after 6 months (0.5 year) = 1,950(1 + (4.25/100)/4)^(0.5 x 4) = 1,950(1 +
0.0425/4)^2 = 1,950(1 + 0.010625)^2 = 1,950(1.010625)^2 = 1,950(1.0213629) =
$1,991.66
Compound interest = Amount - principal (initial deposit) = $1,991.66 - $1,950 = $41.66

Answer:
The positive value of 
will result in exactly one real root is approximately 0.028.
Step-by-step explanation:
Let 
, roots are those values of 
so that 
. That is:
(1)
Roots are determined analytically by the Quadratic Formula:
The smaller root is 
, and the larger root is 
.
has one real root when 
. Then, we solve the discriminant for :
The positive value of will result in exactly one real root is approximately 0.028.
I can't answer this because I don't know what she was starting with
In the given figure, there are two right angled triangles.
Area of triangle = 1/2 × b × h
Area of shaded region = area of larger triangle - area of smaller triangle
= 1/2 × 15 × 18 - 1/2 × 8 × 9
= 135 - 36
= 99 ft^2
Thus, area of shaded region is 99 ft^2.
