Answer:
x+y=15
Step-by-step explanation:
Given equation of
Differentiating both side
It passes through the point (12,3) so
So equation of tangent passing through (12,3) is
as
So x+y =15 will be the equation of tangent which passes though the point (12,3)
Answer:
Surface area = 6l^2
Volume = l^3
If total surface area increased by 2, then the length increased by
Volume then is increased by (l)^3 = 2
l^3
1 :2
Which is not an option in the question so this question clearly has a problem.
First of all It's supposed to be "then" not "than," so I'm not sure who teaches math without even knowing this basic grammar.
Second of all, if the answer is 8:1 the question should be "If <u>each sides</u> of a cube is doubled" not "the lateral surface area." Come to think of it what even is lateral surface area of a cube if all sides of the cube is supposed to be same.
Or, if the answer is 2:1 then, it should be If height lateral surface area of a cube is doubled <u>by doubling the height and without changing the length and width</u>" But, then the the shape would no longer be a cube.
Who even wrote this garbage question what.
