x=-4/3y+-2/3z+2

Step-by-step explanation:

add +4y to both sides

Find the critical numbers of the function. (Enter your answers as a comma-separated list. Use n to denote any arbitrary integer
lyudmila [28]

If

f(\theta)=10\cos\theta+5\sin^2\theta

then the derivative is

f'(\theta)=-10\sin\theta+10\sin\theta\cos\theta

Critical points occur where f'(\theta)=0. This happens for

-10\sin\theta+10\sin\theta\cos\theta=0

-10\sin\theta(1-\cos\theta)=0

\implies-10\sin\theta=0\text{ or }1-\cos\theta=0

In the first case, we find

-10\sin\theta=0\implies\sin\theta=0\implies\theta=n\pi

In the second,

1-\cos\theta=0\implies\cos\theta=1\implies\theta=2n\pi

So all the critical points occur at multiples of \pi, or n\pi. (This includes all the even multiples of \pi.)

How will the graph of
Alexandra [31]

Answer:the answer is A) g(x) is shifted down 2 units

Step-by-step explanation:

Since the last number after the parentheses represents the vertical shift, taking away the +2, leaves you with 0 meaning that there is no vertical shift, so the function lies on the x-axis. The graph shifts down 2 units

Solve: (w)(3w+5)=0. Multiple answers, if any, should be separated by commas. Enter only integer(s) or fraction(s).
sp2606 [1]

Answer:

-\frac{5}{3}

Step-by-step explanation:

Given expression:

                 (w)(3w + 5) = 0

  Expand the parentheses;

                   3w² + 5w  = 0

                    3w²  = -5w

Divide both sides by w;

                    3w  = - 5

                       w = -\frac{5}{3}

Un círculo tiene un radio de 5 cm. ¿Cuántos <br><br>centímetros mide su circunferencia?
denpristay [2]

Answer:

10\pi[/tex]

Step-by-step explanation:

Circunferencia de un círculo = Pi veces diámetro

como el diámetro es igual a la mitad del radio, sabemos que si multiplicamos el radio por dos obtendremos el diámetro del círculo. Por lo tanto, 5 veces 2 = 10. Ahora hacemos 10 veces pi. El cual es 10 pi o 31.4159

Circumference of a circle = Pi times diameter

since the diameter is equal to half the radius, we know that if we multiply the radius by two we will obtain the diameter of the circle. Therefore, 5 times 2 = 10. Now we do 10 times pi. Which is 10 pi or 31.4159
