Hello :
sin(x) + cos(x) = √2(1/√2 sin(x) +1/√2 cos(x))
but : 1/√2 = cos(π/4) = sin(<span> π/4)
</span>sin(x) + cos(x) = √2( cos(π/4)sin(x) + sin( π/4) cos(x)) =√2<span>sin(x + π/4)
</span>because : cos(π/4)sin(x) + sin( π/4) cos(x)=sin(x + π/4) by identity :
sin(a+b) = sina cosb +cosa sinb
The answer is c=50.272, for other problems like this use the formula: The circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle).
Answer:
-16-72v
Step-by-step explanation:
-8*2 = -16
-8*9v = -72v
so, -16 + (-72v) -> -16-72v
Answer:
48 grams
Step-by-step explanation:
pretzels : peanuts : cheese sticks
8 : 5 : 1
64 g : ? g : ? g
grams of peanuts = 5*64 / 8 = 40 g
grams of cheese sticks = 64*1 /8 = 8 g
<u>grams of peanuts and cheese sticks</u> = 40 + 8 = 48 grams
The answer is f(x)=16(1/4)^x
