Answer:
x = π/6, π/2, 5π/6, 3π/2
Step-by-step explanation:
cos x = sin(2x)
Use double angle formula.
cos x = 2 sin x cos x
Move everything to one side and factor.
cos x − 2 sin x cos x = 0
cos x (1 − 2 sin x) = 0
Set each factor to 0 and solve.
cos x = 0
x = π/2, 3π/2
1 − 2 sin x = 0
sin x = 1/2
x = π/6, 5π/6
The total solution is:
x = π/6, π/2, 5π/6, 3π/2
Answer:
i think 27777777777777/100000000000000
Step-by-step explanation:
STEP 1
Bandages: multiply number of total kits by number of bandages per kit
9 * 24= 216 bandages total
STEP 2
Antiseptic Wipes: multiply number of total kits by number of antiseptic wipes per kit
9 * 16= 144 antiseptic wipes total
STEP 3
find difference between steps 1 & 2
= 216 bandages - 144 antiseptic wipes
= 72 more bandages
ANSWER: She packed 72 more bandages than antiseptic wipes.
Hope this helps! :)
Answer:
answer B is correct
Step-by-step explanation:
Hello,
this is not allowed to divide by 0 so we need to find the zeros of
we need x different from -5 and from 3
answer B is correct
