Answer:

x^2+2x+1=0

x^2+(1+1)X+1=0

x^2+X+X+1=0

X(X+1)+1(X+1)=0

(X+1)(X+1)=0

X=-1,X=-1

hope it helps :)

Use logarithmic differentiation to find the derivative of the function. y = sqrt(x)e^x^2(x^2 + 5)^12

padilas [110]

$y=\sqrt x\,e^{x^2}(x^2+5)^{12}=x^{1/2}e^{x^2}(x^2+5)^{1/2}$

Take the logarithm of both sides and expand the right hand side:

$\ln y=\ln\left(x^{1/2}e^{x^2}(x^2+5)^{1/2}\right)$

$\ln y=\ln x^{1/2}+\ln e^{x^2}+\ln(x^2+5)^{12}$

$\ln y=\dfrac12\ln x+x^2\ln e+12\ln(x^2+5)$

$\ln y=\dfrac12\ln x+x^2+12\ln(x^2+5)$

Now take the derivative of both sides with respect to $x$ :

$\dfrac1y\dfrac{\mathrm dy}{\mathrm dx}=\dfrac1{2x}+2x+\dfrac{24x}{x^2+5}$

$\dfrac{\mathrm dy}{\mathrm dx}=\left(\dfrac1{2x}+2x+\dfrac{24x}{x^2+5}\right)y$

$\dfrac{\mathrm dy}{\mathrm dx}=\left(\dfrac1{2x}+2x+\dfrac{24x}{x^2+5}\right)\sqrt x\,e^{x^2}(x^2+5)^{12}$

I'd stop there, but you could condense the right side a bit to get

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{4x^4+21x^2+48x+5}{2x(x^2+5)}\sqrt x\,e^{x^2}(x^2+5)^{12}$

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{4x^4+21x^2+48x+5}{2\sqrt x}e^{x^2}(x^2+5)^{11}$

Hey besties! Can you solve this question i will make you brainlist

Vesna [10]

Answer:

Step-by-step explanation:

Let x be the total no. of strawberries, Let Sue be "S", Let Jim be "J" and Dan be "D"

S = 2x/7

J = 54+S -> J = 54+(2x/7)

D = 78

J+D = 5x/7

54+(2x/7)+78 = 5x/7

132+2x/7 = 5x/7

132 = (5x/7)-(2x/7)

132 = 3x/7

132*7 = 3x

924/3 = x

x = 308.

Therefore, there were initially 308 strawberries in the basket.

Of which; Sue had two-sevenths: 88, Jim had 142 and Dan had 78

To verify our answer, add these to see if we get 308

S+J+D = 308

88 + 142 + 78 = 308

I really need help bad!!

const2013 [10]

Answer:

5. x = 17

7. x = 2

Step-by-step explanation:

The applicable relation is, "the product of the near distance to the circle and the far distance to the circle is the same for each secant." Distance is measured from the point where the secants intersect.

Using the rule, we have ...

7(7+x) = 8(8+13)

7+x = 24 . . . . . . . . . divide by 7

x = 17 . . . . . . . . . . subtract 7

The same rule applies.

7(7 +6x -1) = 9(9 +x +3)

42x +42 = 9x +108 . . . . . . simplify

33x = 66 . . . . . . . . . . . . . subtract 9x+42

x = 2 . . . . . . . . . . . . . . divide by 33
