Jane and Mo have 528 parcels to

Temka [501]

Answer:

Jane gave 132 parcels to Mo.

Step-by-step explanation:

Given total number of parcels both Jane and Mo have = 528.

Let the number of parcels having Jane and Mo be x and y respectively.

$Therefore\ x\ +\ y\ =\ 528\ equation\ 1\\x\ =\ 3y\ equation\ 2$

Now let the number of parcels Jane gives to Mo be z.

$So\ according\ to\ question\ x-z = y+z\\3y-z=y+z(from\ equation\ 2)\\2y=2z\\y=z$

$x+y=528\\3y+y=528\\4y=528\\y=132\\y=z=132$

So the number of parcels Jane give to Mo is 132.

Derivative of (2x+5)^4(5x+2)^-2

Sveta_85 [38]

Use chain rule

$\frac{d}{dx}f(x)g(x)=f'(x)g(x)+g'(x)f(x)$

and also power rule
$\frac{d}{dx} x^m=mx^{m-1}$

so

well, we will say $f(x)=(2x+5)^4$ and $g(x)=(5x+2)^{-2}$
$f'(x)=4(2x+5)^3(\frac{d}{dy}(2x+5))=4(2x+5)^3(2)=8(2x+5)^3$
$g'(x)=-2(5x+2)^{-3}(\frac{d}{dx}(5x+2))=-2(5x+2)^{-3}(5)=-10(5x+2)^{-3}$

so
$\frac{d}{dx}(2x+5)^4(5x+2)^{-2}=8(2x+5)^3(5x+2)^{-2}+(-10(5x+2)^{-3})(2x+5)^4)$

The lengths of a triangle are 12 and 23 meters find the range of possible lengths for the third side

sergij07 [2.7K]

Answer: 11 < x < 35

suppose: the length of the third side is x

because x is the third side of a triangle

=> 23 - 12 < x < 23 + 12

⇔ 11 < x < 35
