Mathematics
1 answer:
Stels [109]3 years ago
7 0

Answer:

x= 7.1

Step-by-step explanation:

use sine because x is the opposite and 10 is the adjacent

set up your equation:

sin(45)= x/10

multiply both sides by 10:

10(sin(45))= (x/10)10

10(sin(45))= x

multiply 10 by sin(45):

7.1=x

This extreme value problem has a solution with both a maximum value and a minimum value. Use Lagrange multipliers to find the ex
pashok25 [27]

Answer with Step-by-step explanation:

We are given that

f(x,y,z)=10x+10y+3z

g(x,y,z)=5x^2+5y^2+3z^2=43

We have to find the extreme values of the function.

f_x(x,y,z)=10,f_y(x,y,z)=10,f_z(x,y,z)=3

g_x(x,y,z)=10x,g_y(x,y,z)=10y,g_z(x,y,z)=6z

\Delta f(x,y,z)=\lambda \Delta g(x,y,z)

Therefore,

10=\lambda 10x\implies x=\frac{1}{\lambda}

10=10y\lambda\implies y=\frac{1}{\lambda}

3=6z\lambda

z=\frac{1}{2\lambda}

Substitute the values in g(x)

Then, we get

\frac{5}{\lambda^2}+\frac{5}{\lambda^2}+\frac{3}{4\lambda^2}=43

\frac{20+20+3}{4\lambda^2}=43

\frac{43}{4\lambda^2}=43

\lambda^2=\frac{43}{4\times 43}

\lambda=\pm\frac{1}{2}

When \lambda=\frac{1}{2} then,

x=2,y=2,z=1

When \lambda=-\frac{1}{2}

Then, x=-2,y=-2,z=-1

f(2,2,1)=10+10+3=23

f(-2,-2,-1)=-10-10-3=-23

Hence, maximum value of f(x,y,z) is 23 at (2,2,1) and minimum value of f(x,y,z) is -23 at (-2,-2 ,-1).

For the functions h and g, which statement is true if h(x) = x and g(x) = (x + 14)?
pickupchik [31]

Answer:

For the functions h and g, which statement is true if h(x) = x and g(x) = (x + 14)?

(F) The graph of g is the result of the graph of h being translated right 14 units.

(G) The graph of g is the result of the graph of h being translated left 14 units.

(H) The graph of g is steeper than the graph of h.

(J) The graph of g is less steep than the graph of h.
