Help?????? Does anyone know the answer to this

1 answer:

5 0

I think it’s B, or 0.10x+0.15(50-x)=0.12(50)

Because 10% would give you 30ml, and 15% would equal 20ml to get 50ml, according to the equation.

A garden is in the shape of a square of length 35 2/5 m. find its (i) perimeter and (ii) area.

Crank

Answer:

perimeter = 56 m

area= 196 m^2

Step-by-step explanation:

perimeter = 4 x sides = 4 x 35(2/5) = 4 x 14 = 56 m

area= sides^2 = (35 x $\frac{2}{5} )^{2}$ = 14^2 = 196 m^2

Determine whether or not F is a conservative vector field. If it is, find a function f such that F = ∇f. (If the vector field is

Elis [28]

In order for F to be conservative, there must be a scalar function f such that the gradient of f is equal to F. This means

$\dfrac{\partial f}{\partial x}=3x^2-2y^2$

$\dfrac{\partial f}{\partial y}=4xy+4$

Integrate both sides of the first equation with respect to x :

$f(x,y)=x^3-2xy^2+g(y)$

Differentiate both sides with respect to y :

$\dfrac{\partial f}{\partial y}=-4xy+\dfrac{\mathrm dg}{\mathrm dy}=4xy+4\implies\dfrac{\mathrm dg}{\mathrm dy}=8xy+4$

But we assume g is a function of y, which means its derivative can't possibly contain x, so there is no scalar function f whose gradient is F. Therefore F is not conservative.
