Step-by-step explanation:
well, it is a combination of 2 shapes.
I, personally, would have split it into the small 2x2 square (in the top right corner) and then into the 6x(7-2) rectangle.
that would be
2x2 + 6x5 = 4 + 30 = 34 cm²
but you started a valid approach too.
you "sliced" off a narrow rectangle along the whole right side. 7x2.
and that leaves now a 4x(7-2) rectangle.
so,
7x2 + 4x5 = 14 + 20 = 34 cm²
yes, this was my answer.
how did this suddenly appear as your answer ?
Answer:
A differnece between the plants is that the vascular plant has vascular vessels to carry water and food to all the different parts of the plant
Step-by-step explanation:
one of my teachers told me this.
Answer:
5 laps
Step-by-step explanation:
We can use ratios to solve
3 minutes 15 minutes
----------------- = ------------------------
1 lap x laps
Using cross products
3x = 15
Divide each side by 3
3x/3 = 15/3
x = 5
He can do 5 laps
The given equation, x.cosec²x = cot x - d/dx x.cot x, is proved using the product rule of differentials.
In the question, we are asked to show that x.cosec²x = cot x - d/dx x.cot x.
To prove, we go by the right-hand side of the equation:
cot x - d/dx x.cot x.
We solve the differential d/dx using the product rule, according to which, d/dx uv = u. d/dx(v) + v. d/dx(u), where u and v are functions of x.
cot x - {x. d/dx(cot x) + cot x. d/dx(x)}
= cot x - {x. (-cosec²x) + cot x} {Since, d/dx(cot x) = -cosec²x, and d/dx(x) = 1}
= cot x + x. cosec²x - cot x
= x. cosec²x
= The left-hand side of the equation.
Thus, the given equation, x.cosec²x = cot x - d/dx x.cot x, is proved using the product rule of differentials.
