So 90^2+90^2=c^2
8100+8100=c^2
16200=c^2
C= ~127.28
Answer:
Step-by-step explanation:
5x^5 - 2x - 4x^4 - 3x^2
5x^5 - 4x^4 - 3x^2 - 2x
<span>X^2= 1/100
x = 1/10
Because 1/10 * 1/10 = 1/100

Answer:
<h2>The specific heat of the metal is 0.274951 calories/gram-degree C.</h2>
Step-by-step explanation:
Let, the specific heat of the container is x calories/gram-degree C.
The container and water gains (18 - 15) = 3 degrees C.
Hence, the transfer of heat is
.
The metal, which is dropped in the water, losses (164 - 18)= 144 degrees C.
Hence, the transfer of heat is
.
As per the given conditions,
.
Sin2x=2sinxcosx, cos2x=1-2sin^2x
sin(2x)+cos(3x)=2sinxcosx+cos(x+2x)
cos(x+2x)=cosx(1-2sin^2(x))-sinx2sinxcosx
sin(2x)+cos(3x)=2sinxcosx(1-sinx)+cosx(1-2sin^2(x))
