Y+ 3/4 = 6
⇒ y= 6 - 3/4
⇒ y= 24/4 - 3/4
⇒ y= 21/4
⇒ y= 5 1/4
The correct answer is y= 5 1/4~
Area of a trapezoid = h/2 ( a + b) where h = height and a and b are the lengths of the 2 parallel sides.
So here we have
Area = 12/2 ( 18 + 23)
= 246 in^2 Answer
ii . volume of a sphere = 4/3 pi r^3 so
1436.03 = 4/3 pi r^3
r^3 = 1436.03 / (4/3 * pi) = 342.827
r = cube root of 342.827 = 7.0 m Answer
Answer:
Step-by-step explanation:25
4cos(x)-2cos(x)=1+2cos(x)-2cos(x)
2cos(x)=1
cos(x)=1/2 (Positive cos are only in the first and 4th quadrants.)
x=π/3,
x=2π - π/3 = 5π/3
