Find the acute angles between the curves at their points of intersection. (The angle between two curves is the angle between the

ir tangent lines at the point of intersection. Give your answers in degrees, rounding to one decimal place. Enter your answers as a comma-separated list.)
y = 6x2,
y = 6x3
I know that they intersect at (1, 6) and I already took the derivatives to find that the slope of the tangent lines are 12 and 18. What do I do now?

Answer:

Step-by-step explanation:

To find the acute angles between the curves at their points of intersection, we find the angle between the tangents to the curve  at their points of intersection.

y = 6x^2,y = 6x^3

I know that they intersect at (1, 6)

Here given that the tangents have slopes as

m_1 =12\\m_2 =18

So angle between the curves = angles between the two tangents

=tan \theta =|\frac{m_1-m_2}{1+m_1m_2} |\\=\frac{8}{1+216} \\\theta = 2.1113 degrees

Thus angle between the curves is 2.113 degrees or arc tan (8/217)

What is the answer to a chef needs to cook 9 potatoes.He has already cooked 7.If each potato takes 3 minutes to cook,how long wi
jok3333 [9.3K]

Answer:it will it take him 6 minutes to cook the rest.

Step-by-step explanation:

The chef needs to cook a total of 9 potatoes. He has already cooked 7 potatoes. That means that the number of uncooked potatoes left is total number of potatoes - number of cooked potatoes. It becomes

9-7 = 2 potatoes

If each potato takes 3 minutes to cook, this means that 2 potatoes will take 3 minutes × 2 j = 6 minutes

Since there are only 2 potatoes left uncooked, it will it take him 6 minutes to cook the rest.

If (a^2 + b^2) (x^2 +y^2) = (ax + by )^2 then which relation is true?​
NikAS [45]

Answer:

Step-by-step explanation:

Hello,

Let's develop both expressions and try to re factorise.

\forall (a,b,x,y) \in \mathbb{R}^4  \\ \\ (a^2+b^2)(x^2+y^2)=(ax+by)^2\\ \\(ax)^2+(ay)^2+(bx)^2+(by)^2=(ax)^2+(by)^2+2(ax)(by)\\ \\ (ay)^2+(bx)^2-2(ay)(bx)=0\\ \\ (ay-bx)^2=0\\ \\ ay-bx=0\\ \\ \boxed{\sf \bf ay=bx}

Thanks
