Answer:
we have the expression as;
1/sin u cos u
Step-by-step explanation:
tan u = sin u/cos u
cot u = cos u/sin u
Thus;
sin u/cos u + cos u/sin u
The lcm is sin u cos u
Thus, we have that;
(sin^2 u + cos^2 u)/sin u cos u
But ; sin^2 u + cos^2 u = 1
so we have ;
1/sin u cos u
Equation is (x+2)^2 - x^2 = 7676
solve the equation by first opening the bracket of (x+2)^2 by A^2 + 2AB +C^2
you'll end up with 4x + 4 = 7672
thus x = 1918 and the next number is 1920.

Answer:
Option A. 14.13 cu. in
The volume of the water balloon is 14.13 in³
Step-by-step explanation:
First we calculate the radius
r = 3in / 2
To calculate the volume of a sphere we have to use the following formula:
V = volume
r = radius = 1.5in
π = 3.14
V = ⁴⁄₃πr³
we replace with the known values
V = ⁴⁄₃ * 3.14 * (1.5in)³
V = 4.187 * 3.375 in³
V = 14.13 in³
The volume of the water balloon is 14.13 in³
