Answer:
31.9
Step-by-step explanation:
We have the hypotonouse and need the adjacent side
to solve for x we will use CAH
Cos(15)=x/33
33cos(15)=x
x=31.87555 which rounds to 31.9
Hello there!
how are you! Great okay!
so the answer to our question is ∴ The temperatures from Monday to Friday are – 30C, 00C, 30C, 60C and 90C respectively
Derivatives:
cos --> -sin
sin ----> cos
f' = cost - sint
f ' (pi) = cos(pi) - sin(pi)
= -1 -0
= -1
Answer:-9+2I
Step-by-step explanation: MUTIPLYING THE SECOND BRACKET BY THE NEGATIVE SIGN.
(-3-3I)(-6+5I)
COLLECTING LIKE TERMS
(-3-6)(-3I+5I)
=-9+2I
The first thing we must do for this case is to define variables:
w: pounds of meat
x: carton of milk
y: loaf of bread
z: cereal breakfast box
We write the system of equations:
0.70x + 0.60y + 0.50z + 1.50w = 10
x = 2y
z = y + 1
w = z
Solving the system we have:
w = 3
x = 4
y = 2
z = 3
Answer:
3 pounds of meat
4 cartons of milk
2 loaves of bread
3 boxes of breakfast cereal
