Anyone know how to expand 5p(p-3)

Katyanochek1 [597]

I believe what your asking is just multiplying it together so 5p(p-3) would be 5p2-15p. the p2 is p squared or a little 2 on top of the p. Hope I helped!

Un boligrafo cuesta 30 ptas mas que un lapiz. Un muchacho ha comprado 8 boligrafos y 15 lapices. En total le han costado 700 pta

Firdavs [7]

Por un sistema de ecuaciones, tiene-se que:

Cada lapiz cuesta 20 ptas.
Cada boligrafo cuesta 50 ptas.

-------------------------

Considera-se un sistema de ecuaciones, con cada boligrafo custando x y cada lapiz custando y.

Boligrafo cuesta 30 mas que un lapiz, o sea, $x = 30 + y$
8 boligrafos y 15 lapices cuesta 700, o sea, $8x + 15y = 700$

-------------------------

Aplicando el primer ecuación en la segunda, tiene-se el cuesto de cada lapiz:

$8x + 15y = 700$

$8(30 + y) + 15y = 700$

$240 + 8y + 15y = 700$

$23y = 460$

$y = \frac{460}{23}$

$y = 20$

Cada lapiz cuesta 20 ptas.

-------------------------

Por fin, el cuesto de cada boligrafo es dado por:

$x = 30 + y = 30 + 20 = 50$

Cada boligrafo cuesta 50 ptas.

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

snow_tiger [21]

$\nabla f=(xy\cos xy+\sin xy)\,\vec\imath+x^2\cos xy\,\vec\jmath$

then we should have

$\dfrac{\partial f}{\partial y}=x^2\cos xy\implies f(x,y)=x\sin xy+g(x)$

Differentiating with respect to $x$ gives

$\dfrac{\partial f}{\partial x}=xy\cos xy+\sin xy=\sin xy+xy\cos xy+g'(x)$

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

So $F$ is indeed conservative, and

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

Which equation is equivalent to????

vesna_86 [32]

3² = x + 5. The equivalent equation to log₃(x+5) = 2 is 3² = x + 5.

In order to solve this problem we have to know about Logarithm.

Logarithm is defined as the exponent of a power with a certain base, that is, the number to which a given base must be raised to obtain a given result.

logₐ b = x ----------> aˣ = b

Solving for log₃(x+5) = 2 where a = 3, x = 2, and b = x + 5

3² = x + 5
