Answer:

it is C. Q3- Q1 tell me if it was right or not

OR if it is for a listing order it would be this List in ascending order:-

32 39 45 48 50 57 65 68 70

Q1 = (39+45)/2 = 42

Q2 = 50

Q3 = (65+68)/2 = 66.5

Solve the equation.<br> 6x−12=3(2x+5)
nordsb [41]

Let's solve your equation step-by-step.

6x−12=3(2x+5)

Step 1: Simplify both sides of the equation.

6x−12=3(2x+5)

6x+−12=(3)(2x)+(3)(5)(Distribute)

6x+−12=6x+15

6x−12=6x+15

Step 2: Subtract 6x from both sides.

6x−12−6x=6x+15−6x

−12=15

Step 3: Add 12 to both sides.

−12+12=15+12

0=27

Answer:

There are no solutions.

Find an equation of the tangent line to the curve 2(x2+y2)2=25(x2−y2) (a lemniscate) at the point (−3,1). An equation of the tan
valina [46]

2(x^2+y^2)^2=25(x^2-y^2)

Let y=y(x), so that differentiating both sides wrt x gives

4(x^2+y^2)\left(2x+2y\dfrac{\mathrm dy}{\mathrm dx}\right)=25\left(2x-2y\dfrac{\mathrm dy}{\mathrm dx}\right)

If x=-3 and y=1, the above reduces to

40\left(-6+2\dfrac{\mathrm dy}{\mathrm dx}\right)=25\left(-6-2\dfrac{\mathrm dy}{\mathrm dx}\right)\implies\dfrac{\mathrm dy}{\mathrm dx}=\dfrac9{13}

This is the slope of the tangent line, which has equation

y-1=\dfrac9{13}(x+3)\implies\boxed{y=\dfrac{9x+40}{13}}
