Hey there!

$Answer:\boxed{5,000}$

$Explanation:$

Let's review the place value so we know how we got our answer.

7(70,000) 5(5,000), 9(900) 8(80) 4(04)

The one we are looking for is the place value of 5. The number 5 is in the thousands place. So now we have our answer!

$\boxed{5,000}\text{ is the answer.}$

Hope this helps!

Use Lagrange multipliers to find the maximum and minimum values of (i) f(x,y)-81x^2+y^2 subject to the constraint 4x^2+y^2=9. (i

sp2606 [1]

i. The Lagrangian is

$L(x,y,\lambda)=81x^2+y^2+\lambda(4x^2+y^2-9)$

with critical points whenever

$L_x=162x+8\lambda x=0\implies2x(81+4\lambda)=0\implies x=0\text{ or }\lambda=-\dfrac{81}4$

$L_y=2y+2\lambda y=0\implies2y(1+\lambda)=0\implies y=0\text{ or }\lambda=-1$

$L_\lambda=4x^2+y^2-9=0$

If $x=0$ , then $L_\lambda=0\implies y=\pm3$ .
If $y=0$ , then $L_\lambda=0\implies x=\pm\dfrac32$ .
Either value of $\lambda$ found above requires that either $x=0$ or $y=0$ , so we get the same critical points as in the previous two cases.

We have $f(0,-3)=9$ , $f(0,3)=9$ , $f\left(-\dfrac32,0\right)=\dfrac{729}4=182.25$ , and $f\left(\dfrac32,0\right)=\dfrac{729}4$ , so $f$ has a minimum value of 9 and a maximum value of 182.25.

ii. The Lagrangian is

$L(x,y,z,\lambda)=y^2-10z+\lambda(x^2+y^2+z^2-36)$

with critical points whenever

$L_x=2\lambda x=0\implies x=0$ (because we assume $\lambda\neq0$ )

$L_y=2y+2\lambda y=0\implies 2y(1+\lambda)=0\implies y=0\text{ or }\lambda=-1$

$L_z=-10+2\lambda z=0\implies z=\dfrac5\lambda$

$L_\lambda=x^2+y^2+z^2-36=0$

If $x=y=0$ , then $L_\lambda=0\implies z=\pm6$ .
If $\lambda=-1$ , then $z=-5$ , and with $x=0$ we have $L_\lambda=0\implies y=\pm\sqrt{11}$ .

We have $f(0,0,-6)=60$ , $f(0,0,6)=-60$ , $f(0,-\sqrt{11},-5)=61$ , and $f(0,\sqrt{11},-5)=61$ . So $f$ has a maximum value of 61 and a minimum value of -60.

HURRY PLSSS

vodka [1.7K]

Answer:

Step-by-step explanation:

the answer is c because you multiply 4 and 2 and get 8 and multiply 8 by 8 and get 64 then you use 4 again and multiply 64 by 4 so you get 256 and round that 254

Hey!

sashaice [31]

Answer:

angle y is 64⁰

Step-by-step explanation:

There are 2 ways to solve this.

first,

they are alternate angles

second,

you can solve by

180-64=116 (on a straight line)

180-116=64⁰

I'm not really good at explaining but hope this helps :)

The figure below shows a rectangle with a diagonal drawn.

Kipish [7]

Answer:

Option B. sin(s) = cos(u)

Step-by-step explanation:

The rest of the question is the attached figure.

Complementary angles - two angles that add to 90 degrees.

The sine of one of them will be equal to the cosine of other angle.

For the attached figure:

The set all complementary angles are:

angle s and angle t
angle u and angle v
angle s and angle u
angle t and angle v

We will check the options:

A. sin(t) = sin(u) ⇒(wrong) because t and u are not complementary angles

B. sin(s) = cos(u) ⇒ (True) ⇒ s and u are complementary angles and sine of one of them will be equal to the cosine of other angle.

C. cos(s) = sin(v) ⇒(wrong) because t and u are not complementary angles

D. cos(t) = cos(v) ⇒(wrong) because t and v are complementary angles but sine of one of them should be equal to the cosine of other angle.

The answer is option B. sin(s) = cos(u)
