Using scientific notation, what is the solution to (2.82 * 104) * (3.1 * 103)?

MArishka [77]

Answer: Choice A) 8.742 * 10^7

=====================================

Work Shown:

$(a * 10^b) \times (c * 10^d) = a*c*10^{b+d}\\\\(2.82 * 10^4) \times (3.1 * 10^3) = 2.82*3.1*10^{4+3}\\\\(2.82 * 10^4) \times (3.1 * 10^3) = 8.742*10^{7}\\\\$

Extra info:

$8.742 * 10^7 = 87,420,000$

which is a little over 87.4 million

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

gavmur [86]

$\nabla f=(ye^x+\sin y)\,\vec\imath+(e^x+x\cos y)\,\vec\jmath$

then

$\dfrac{\partial f}{\partial x}=ye^x+\sin y\implies f(x,y)=ye^x+x\sin y+g(y)$

Differentiating with respec to $y$ gives

$\dfrac{\partial f}{\partial y}=e^x+x\cos y=e^x+x\cos y+g'(y)$

$\implies g'(y)=0\implies g(y)=C$

So $F$ is indeed conservative, and

$f(x,y)=ye^x+x\sin y+C$
