That would be s × .05 = (answer)
s + (answer)
X and y vary inversely:
y=k/x
y=8/3 when x=8
8/3=k/8
Solving for k:
8(8/3)=k
64/3=k
k=64/3
y=k/x
y=(64/3)/x
y=(64/3)(1/x)
y=64/(3x)
when x=4→y=64/(3x)=64/(3(4))→y=16/3
Answer: Second Option y=64/(3x); 16/3
Answer: all of them are correct! great job!!!1
Step-by-step explanation:
.4 is 40 percent because you move the decimal two spaces to the right so it would be 40 percent, same as the others!
The answer here has to do with order of operations rules (PEMDAS).
–2^4 comes out to -16, because the exponentiation MUST be done first. That gives you 16, which you then preface with the - symbol.
(–2)^4 Here the parentheses make the difference: (-2)^4 requires that we take the 4th power of (-1) and mult. that by the 4th power of 2, which is 16.
So, yes, –2^4 and (–2)^4 are different.
What about –2^3 and (–2)^3?
Again we must do exponentiation first. 2^3 is 8, which we then preface with -. Result: -8. (–2)^3 is equivalent to (1)^3 * 2^3, or (-1)*8, or -8. So these two results are identical.
Perhaps it would help to recall that
-1 = -1
(-1)^2 = 1
(-1)^3 = -1
(-4)^4 = 1
and that this pattern repeats itself after you've written each group of 4 lines.
