Hello,
When you compose 2 reciprocals functions, you will find 1.
ex f(x)=√x and g(x)=x² , x>=0
so that g(f(x))=(√x)²=x
sin(cos(0))=sin(1)=0,84147... rad and not 1.
Reciprocal function of sin (x) is arcsin(x).
Reciprocal function of cos (x) is arccos(x).
The changed digit is the third to the left of the decimal point, so is in the hundreds place.
The value of 8 hundred is 5 hundred more than the value of 3 hundred. The second number is 500 more than the first.
Answer:
y = 3 + 1/2 * x
Step-by-step explanation:

So y=2x is the only answer that fit y=kx, while k=2

= ?
Multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:
4 × 1
4 × 2
=
4
8
The Greatest Common Factor (GCF) of 4 and 8 is 4. The result can be simplified by dividing both the numerator and denominator by 4.
