Answer:
8 3/25 because 8.12 is 8 12/100 and when you simplify 12/100 you get 3/25
The answer is 3 and 5/6 because 6 goes into 23 3 times with 5 left over. then you put the five over the denominator 6. make sense dear?
64cm2 but make the number two small and in the corner of the m
70 square feet
It depends on what you mean by the delimiting carats "^"...
Since you use parentheses appropriately in the answer choices, I'm going to go out on a limb here and assume something like "^x^" stands for

.
In that case, you want to find the antiderivative,

Complete the square in the denominator:

Now substitute

, so that

. Then

which simplifies to

Now, recall that

. But we want the substitution we made to be reversible, so that

which implies that

. (This is the range of the inverse sine function.)
Under these conditions, we have

, which lets us reduce

. Finally,

and back-substituting to get this in terms of

yields
