Answer:
P≈28.28cm
d = Diagonal 10cm
Using the formulas
P=4a
d=2a
Solving for P
P=22d=2·2·10≈28.28427cm
Step-by-step explanation:
Step-by-step explanation:
sin(2x) + cos(3x)
Use double angle formula sin(2x) = 2 sin x cos x.
Use triple angle formula cos(3x) = 4 cos³x − 3 cos x.
Substitute:
2 sin x cos x + 4 cos³x − 3 cos x
Answer:
1.03
Step-by-step explanation:
Per capita just means per unit of population, or per person. This question is asking how many cell phones there were in the United States per person in 2014. We can use simple division to determine that the answer is 327.6/317.9 or about 1.03 when rounded to the nearest hundredth.

Answer:
y = 4x - 3
Explanation:
4x – y + 6 = 9 Subtract 6 from each side
4x – y = 3 Subtract 4x rom each side
-y = -4x + 3 Multiply each side by -1
y = 4x - 3
