Find equations of both the tangent lines to the ellipse x^2 + 4y^2 = 36 that pass through the point (12, 3).y = (smaller slope)y
Bingel [31]

Answer:

x+y=15

Step-by-step explanation:

Given equation of x^2+4y^2=36

Differentiating both side 2x+8y\frac{dy}{dx}=0

\frac{dy}{dx}=\frac{-x}{4y}

It passes through the point (12,3) so

\frac{dy}{dx}=\frac{-12}{4\times 3}=1

So equation of tangent passing through (12,3) is

y-12=-1(x-3) as y-y_1=-m(x-x_1)

So x+y =15 will be the equation of tangent which passes though the point (12,3)

A rectangular box is 6 inches long, 5 inches wide and 7 inches tall. What is the approximate length of its longest diagonal?
xxTIMURxx [149]

Answer:

10.5 inches

Step-by-step explanation:

The length of the longest diagonal is across two opposite points of the solid, namely

L = sqrt ( 6^2 + 5^2 + 7^2)

= sqrt (36+25+49)

= sqrt(110)

= 10.5"

Solve for x. 5^11x=25^x+9
4vir4ik [10]
   
\displaystyle\\&#10;5^{11x}=25^{x+9}\\\\&#10;5^{11x}=\Big(5^2\Big)^{x+9}\\\\&#10;5^{11x}=5^{2(x+9)}\\\\&#10;11x = 2(x+9)\\\\&#10;11x = 2x+18\\\\&#10;11x - 2x = 18\\\\&#10;9x = 18\\\\&#10;x =  \frac{18}{9} = \boxed{2}

Please add explanation as well.

It is the first one. Three times a number means 3x. The sum of 3x and 7 is 3x + 7 because sum means additions. And 3x + 7 is greater than four times the number which is 4x and greater than is this symbol >. So 3x + 7 > 4x
