Answer:
1/8
Step-by-step explanation:
sin²(π/8) − cos⁴(3π/8)
Use power reduction formulas:
1/2 (1 − cos(2×π/8)) − 1/8 (3 + 4 cos(2×3π/8) + cos(4×3π/8))
Simplify:
1/2 (1 − cos(π/4)) − 1/8 (3 + 4 cos(3π/4) + cos(3π/2))
1/2 (1 − √2/2) − 1/8 (3 + 4 (-√2/2) + 0)
1/2 − √2/4 − 1/8 (3 − 2√2)
1/2 − √2/4 − 3/8 +√2/4
1/2 − 3/8

Okay so your going to multiple tye 2 number okay then your going to do all numbers
Use a phone so u can multiple
Answer:
Step-by-step explanation:
It’s c
The scale factor is 1.5, which means that the revised
chamber is larger. The new dimensions are just the old dimensions times 1.5.
The volume of the revise chamber is:
V = (1/3) (PI) [(D/2)^2] (H)
= (1/3) (PI) {[(5.7)(1.5)/2]^2} [(12)(1.5)]
= 344.4874 in3

It is (c+d)
you can basically use FOIL (first,outside,inside,last) to solve this.
you know the first term of the factor has to be C because of the c^2
the second then has to be D because you haven't seen D in the factor yet and it is in the equation.
then you know from the equation that the terms with D are not negative so D isn't negative so you have form the information above (c+d)
