I think it would be 5/7 because it says that square B is 5/7 of square A.
Answer:
6 rainy days
Step-by-step explanation:
Instead of using the quotient rule, you can first expand <em>y</em> :
<em>y</em> = (4<em>x</em> - 1)^2 / <em>x</em> ^2 = (16<em>x</em> ^2 - 8<em>x</em> + 1) / <em>x</em> ^2 = 16 - 8/<em>x</em> + 1/<em>x</em> ^2
Then the derivative is
d<em>y</em>/d<em>x</em> = -8/<em>x</em> ^2 - 2/<em>x</em> ^3
The tangent to the curve at (-1, 25) then has a slope or gradient of
d<em>y</em>/d<em>x</em> = -8/(-1)^2 - 2/(-1)^3 = -6
Answer:
A
Step-by-step explanation:
The formula for flipping smth over the x axis is(x,y)→(x,−y)
just flip the symbol on the second #
your points are:
(-4,-2)→(-4,2)
(0,-4)→(0,4)
(-4,-5)→(-4,5)
Once you graph it, youll see that the shapes are congruent, just flipped, therefore the answer is A
