Answer:
never because you're multiplying the number -2 times so it will be positive only if the variable is positive.
Step-by-step explanation:
what if x=2?
2^-2
=
1
/2*2
=
1
/2^2
=
1
/4 or 0.25
what if x=-5?
-5^-2
=−1*5−2
=−1* 1
/5*5
=
−1
/5*5
=
−1
/5^2
=
−1
/25 or-0.04
n
Answer:
16
Step-by-step explanation:
Let S is smart car and T is Toyota car
Case 1: 6 smart cars and 7 Toyota's = 6S + 7T
Case 2: 8 smart cars and 4 Toyota's
When 2 smart cars increase = 3 Toyota's cars descrease
So the ratio between them is:
2S = 3T
<=> S= 3/2T
so the maximum number of toyotas aboard the ferry
6*3/2T + 7T = 16 T
Using the chain rule.
<span><span>sin^3</span>(x) = [sin(x)<span>]^3
</span></span><span><span>d/<span>dx</span></span>[sin(x)<span>]^3</span>∗<span>d/<span>dx</span></span>[sin(x)]
</span>d/dx sinx = cosx
d/dx<span> cosx = -sinx </span>
d/dx<span> (-sinx) = -cosx </span>
d/dx <span>(-cosx) = sinx
back to where we started from!!! </span>
So,
repeat repeat repeat !!
Answer: The correct answer is Choice D.
A tetrahedron is another name for a triangular prism. When you look at a tetrahedron it only has 4 different sides. If you take a cross section, the largest number of sides that you could have would be 4. There is no way to get an 8 sided octagon.
