Answer:

The correct answer is option A 93.75\\ $

Step-by-step explanation:

Cost of 8 pounds of Pepperoni when cost of 1 pound of Pepperoni is 3.15\\ $

= 8 * 3.15\\= 25.2\\

Cost of 15 pounds of cheese when cost of 1 pound of cheese is 1.85\\$ = 15 * 1.85\\= 27.75\\

Cost of 12 pounds of sausage when cost of 1 pound of sausage is 3.40\\ $ = 12 * 3.40\\= 40.8\\

The total cost of 8 pounds of pepperoni, 15 pounds of cheese, and 12 pounds of sausage

= 25.2 + 27.75 + 40.8\\= 93.75\\ $

Find the maximum and minimum values of the function f(x,y)=2x2+3y2−4x−5 on the domain x2+y2≤100. The maximum value of f(x,y) is:
ryzh [129]

First find the critical points of <em>f</em> :

f(x,y)=2x^2+3y^2-4x-5=2(x-1)^2+3y^2-7

\dfrac{\partial f}{\partial x}=2(x-1)=0\implies x=1

\dfrac{\partial f}{\partial y}=6y=0\implies y=0

so the point (1, 0) is the only critical point, at which we have

f(1,0)=-7

Next check for critical points along the boundary, which can be found by converting to polar coordinates:

f(x,y)=f(10\cos t,10\sin t)=g(t)=295-40\cos t-100\cos^2t

Find the critical points of <em>g</em> :

\dfrac{\mathrm dg}{\mathrm dt}=40\sin t+200\sin t\cos t=40\sin t(1+5\cos t)=0

\implies\sin t=0\text{ OR }1+5\cos t=0

\implies t=n\pi\text{ OR }t=\cos^{-1}\left(-\dfrac15\right)+2n\pi\text{ OR }t=-\cos^{-1}\left(-\dfrac15\right)+2n\pi

where <em>n</em> is any integer. We get 4 critical points in the interval [0, 2π) at

t=0\implies f(10,0)=155

t=\cos^{-1}\left(-\dfrac15\right)\implies f(-2,4\sqrt6)=299

t=\pi\implies f(-10,0)=235

t=2\pi-\cos^{-1}\left(-\dfrac15\right)\implies f(-2,-4\sqrt6)=299

So <em>f</em> has a minimum of -7 and a maximum of 299.

Rearrange the equation a = 1/2 b to make b the formula
Evgesh-ka [11]

Answer: b = 2a

Step-by-step explanation:

<u>Original equation</u>

a = (1/2) b

<u>Multiply 2 on both sides</u>

a * 2 = (1/2) b * 2

\Large\boxed{b=2a}

Hope this helps!! :)

How do I solve this? It's so confusing.
Neporo4naja [7]
If I follow the angle degrees that they gave, your answers would be as follows:
I=145°
S=155° or 90°
E=78°
L=120° or 55°

Maybe this is right, sorry it took so long.
