The cost of the burger went up 2%/ and you can also subtract 6 from8 and get the answer. Thank you have a nice day

Let II be the tangent plane to the graph of f(x, y) = 8 – 2x^2 – 3y^2 at the point (1, 2,-6). Let S, x² + y^2 + z = 4 be another

stealth61 [152]

Let $F(x,y,z)=f(x,y)-z$ . The tangent plane to $f(x,y)$ at (1, 2, -6) has equation

$\nabla F(1,2,-6)\cdot(x-1,y-2,z+6)=0$

We have

$\nabla F(x,y,z)=(-4x,-6y,-1)\implies\nabla F(1,2,-6)=(-4,-12,-1)$

Then the tangent plane has equation

$(-4,-12,-1)\cdot(x-1,y-2,z+6)=0\implies -4(x-1)-12(y-2)-(z+6)=0\implies 4x+12y+z=22$

Let $g(x,y)=4-x^2-y^2$ , and $G(x,y,z)=g(x,y)-z$ . The tangent plane to $S$ at a point $(a,b,c)$ is

$\nabla G(a,b,c)\cdot(x-a,y-b,z-c)=0$

We have

$\nabla G(x,y,z)=(-2x,-2y,-1)\implies \nabla G(a,b,c)=(-2a,-2b,-1)$

so that this plane has equation

$(-2a,-2b,-1)\cdot(x-a,y-b,z-c)=0\implies2ax+2by+z=2a^2+2b^2+c$

In order for this plane to be parallel to the previous plane, we need to have

$\begin{cases}2a=4\\2b=12\end{cases}\implies a=2,b=6\implies g(a,b)=c=-36$

so the point we're looking for is (2, 6, -36).

Ratios- 3:6, for every 3 kids there are 6 adults, if there are 120 adults, how many kids are there?

dimulka [17.4K]

There are 60 kids. You just have to divide 120 by 2.

The graph behavior of the function that satisfied the conditions given are:

Horizontal asymptote at y = 0.

Vertical asymptotes at x = -1 and x = 1.

<h3>What are the asymptotes of a function f(x)?</h3>

The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator, or values of x for which the value of the limit goes to infinity.

The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity, that is, the limit of f(x) as x goes to infinity.

Hence, for this problem, the graph behavior is given by the following asymptotes:

Horizontal asymptote at y = 0.

Vertical asymptotes at x = -1 and x = 1.

Need to zoom in can any find these two out for me?

Ber [7]

Answer:

9. Juanita's recipe.

10. Leon's recipe.

Step-by-step explanation:

9. All you need to do is convert the numbers into fractions.

Juanita's recipe: 4 parts lemon, 2 parts sugar. Lydia's recipe: 5 parts lemon and 3 parts sugar. So in order to find the lemon amount in each recipe convert into this fraction:

lemon/sugar

Juanita: lemon/sugar= 4 lemon/2 sugar

Lydia: lemon/sugar= 5 lemon/3 sugar

The LCM is 6 so that is the denominator.

Juanita: 4 lemon/2 sugar= 12 lemon/6 sugar

Lydia: 5 lemon/3 sugar= 10 lemon/6 sugar

The ratio is 4:2= ?:6 and 5:3= ?:6

Juanita has 12 lemon and Lydia has 10, so Juanita has more lemons.

10. Same as number 9.

Use the fraction peanuts/pretzels because it wouldn't work if peanuts is on the bottom otherwise both Leon and Cisco's peanut amount will be the same. SO put peanuts over pretzels, so pretzels will be the denominator so we can find the peanut amount.

peanuts/pretzels

Leon: peanuts/pretzels= 3 peanuts/8 pretzels

Cisco: peanuts/pretzels= 2 peanuts/6 pretzels

The LCM is 24 so that is the denominator.

Leon: 3 peanuts/8 pretzels= 9 peanuts/24 pretzels

Cisco: 2 peanuts/6 pretzels= 8 peanuts/24 pretzels

The ratio is 3:8= ?:24 and 2:6= ?:24

Leon has 9 peanuts and Cisco has 8, so Leon has more peanuts.
