Answer:
261.5 ft^2
Step-by-step explanation:
Surface Area of a rectangular prism = Length x Width x Height
= 8.5ft x 6ft x 5.5ft
= 261.5 ft
Answer:
Hello, I believe the answer is C, because you're adding 2 and 3 then getting the quotient of y. Hope this helps.
Its wrong for x = 2
y = (3/4) * 2^2 = 3 (NOT 4)
Answer:
cos(60) cos(-20) - sin(60) sin(-20) = cos (40)
Step-by-step explanation:
Using the trigonometric identity rule:
Given that:
cos(60) cos(-20) - sin(60) sin(-20)
Let A = 60 and B = -20
then;
Using identity rule:
Therefore, the following as a function of a single angle is cos (40)
