Answer:
1) 10
2) 65
3) 125
Step-by-step explanation:
Usually you will see something like g(x) or f(x)
domain means all the x's
so, think of g(4) meaning g(x=4) and g(4 in the domain).
look for 4 on the domain side
you know that f(x) = y
range means all the y's
so its basically saying, look on the domain side for 4 and see what comes out (or =) on the range side.
in this case, it's B) 5
The rule for dividing fractions is "invert and multiply." What you invert is the denominator fraction.
Example: (1/3) / (4/5) = (1/3)×(5/4) . . . . . the denominator 4/5 has been inverted to 5/4 and is now a multiplier.
All the rest of the rules for fractions are unaltered--conversion from mixed numbers to improper fractions, addition and subtraction--they're all the same.
Answer:
Step-by-step explanation:
Required to prove that:
Sin θ(Sec θ + Cosec θ)= tan θ+1
Steps:
Recall sec θ= 1/cos θ and cosec θ=1/sin θ
Substitution into the Left Hand Side gives:
Sin θ(Sec θ + Cosec θ)
= Sin θ(1/cos θ + 1/sinθ )
Expanding the Brackets
=sinθ/cos θ + sinθ/sinθ
=tanθ+1 which is the Right Hand Side as required.
Note that from trigonometry sinθ/cosθ = tan θ
