The first one and it's written as a(-1)(n-1). The parenthesis around the n-2 are important
Never,because obtuse angle is an angle measuring between 90 and 180
and if an angle measures 180 then it is a straight angle
Answer:
formula to find volume of sphere =4/3*22/7*3^3
=113.1cm
Answer:
Width = 2 feet
Length = 6 feet
Explanation:
Variables:
Perimeter = p
Length = l
Width = w
Equation:
2w + 2l = p
It is given that:
l = 3w
and
p = 16 feet
With this information, we can rewrite the equation (substitute)
2w + 2(3w) = 16
Simplify
2w + 6w = 16
Add
8w = 16
Divide both sides of the equation by 8
Width = 2 feet
Length = 3(w) = 3(2) = 6 feet
Hope this helps :)
