Answer:
3.
Step-by-step explanation:
sin 32 / (1 + tan 45) * 6 / cos 58
= sin 32 / 2 * 6 / cos 58 ( since tan 45 = 1)
= 3 sin 32 / cos 58
Note sine 32 = cos (90 - 32) = cos 58, so we have:
= 3 sin 32 / sin 32
= 3.
Expression 3,
because 6 and 8 are factors of 48. Since positive 6 & 8 are the two numbers of choice, the product will be positive. My answer is reasonable because if you were to multiply positive 8 and 6 you will get positive 48.
Let’s make up a random function, say:
f(x) = x^6
Now by power laws we can break this up into two parts:
f(x) = (x^2)*(x^4)
Since we are now multiplying two functions we can apply the product rule:
f’(x) = (2x)(x^4) + (x^2)(4x^3)
Now we can simplify since we are only dealing with x’s:
f’(x) = 2x^5 + 4x^5
f’(x) = 6x^5
If we do the power rule of our initial function, you will find that the two are equal.
Hope this helps!!
