Answer:
None of the options are true.
Step-by-step explanation:
We are given with the following parts;
A. 100 x 1,000 = 107
B. 10 x 1,000 = 105
C. 0.01 x 103 = 100
D. 0.001 x 105 = 100
The first statement that 100 x 1,000 = 107 is false because the multiplication of the numbers 100 and 1,000 gives the result of 100,000 but in question; it is written as 107, So, this is false.
The second statement that 10 x 1,000 = 105 is false because the multiplication of the numbers 10 and 1,000 gives the result of 10,000 but in question; it is written as 105, So, this is false.
The third statement that 0.01 x 103 = 100 is false because the multiplication of the numbers 0.01 and 103 gives the result of 1.03 but in question; it is written as 100, So, this is false.
The fourth statement that 0.001 x 105 = 100 is false because the multiplication of the numbers 0.001 and 105 gives the result of 0.105 but in question; it is written as 100, So, this is false.
Hence, all the statements are false.
C the time it take ice to melt as a function of temperature
_ π/3 · sin π/6 = 1/2 · ( sin π/2 - sin π/6 )
Lets start from the right side of the equation:
1/2 · ( sin π/2 - sin π/6 ) = 1/2 · ( 1 - 1/2 ) = 1/2 · 1/2 = 1/4
So the left side must be equal:
_ π/3 · sin π/6 = 1/4
_ π/3 · 1/2 = 1/4
_ π/3 = 1/4 : 1/2 = 1/4 · 2/1 = 1/2
cos π/3 = 1/2
Answer:
cos π/3 · sin π/6 = 1/2 ( sin π/2 - sin π/6 )
Expand out, this literally just wants you to multiply everything by -1.
so 7*-1 = -7
-c*-1 = c
thus putting them together to get -7+c which is just c-7
G(x) - f(x) = -2x -5
Since f(x) and g(x) has the same domain of R, so the domain should still be R(if you don't consider complex numbers)
