Let hh be the set of all points in the second quadrant in the plane v=ℝ2v=r2. that is, h={(x,y)∣x≤0,y≥0}h={(x,y)∣x≤0,y≥0}. is hh

BaLLatris [955]

No, $H$ is not a subspace of $V$ . A simple counter-example to the contrary: let $h\in H$ with $h=(-1,0)$ . However, scaling by -1 gives the vector $-h=(1,0)$ and $-h\not\in H$ .

The cost of producing x bags of dog food is given by C(x) = 800 + 400 + 10x - x where 0 SX 55000. Find the marginal-cost functio

nikdorinn [45]

Answer:

The marginal-cost function is;

c'(x)= (20x-1)/(2√(400 + 10x² - x))

Completed question;

The cost of producing x bags of dog food is given by C(x) = 800 + √(400 + 10x² - x) where 0≤x≤55000. Find the marginal-cost function.

The marginal-cost function is c'(x)=

(Use integers or fractions for any numbers in the expression.)

Step-by-step explanation:

The marginal-cost function is c'(x)= = dC(x)/dx

Where;

C(x) = 800 + √(400 + 10x² - x)

c'(x) = d(800 + √(400 + 10x² - x) )/dx

Using function of function rule of differentiation or chain rule;

c'(x) = (20x-1)×(1/2√(400 + 10x² - x))

c'(x) = (20x-1)/(2√(400 + 10x² - x))

The marginal-cost function is;

c'(x)= (20x-1)/(2√(400 + 10x² - x))

Hence missing value in the solution to the equation is:(-5,2)

Step-by-step explanation:

We are given the equation:

$x-5y= -15$

and we need to complete the missing value in the solution to the equation

(-5,?)

Since the solution is in the form of ordered pair, so first value represent value of x and second value represents value of y i.e (x,y)

So, x= -5, Now finding y:

Putting value of x in given equation:

$x-5y= -15\\-5-5y= -15\\-5y=-15+5\\-5y=-10\\y=-10/-5\\y=2$

So, value of y is 2

Hence missing value in the solution to the equation is:(-5,2)

Answer: 65 degrees

Step-by-step explanation:

If you learned angles, you would know that m∠2 and m∠6 are corresponding angles since it was already given that a║b.

Reasoning: m∠2=m∠6; if m∠2=65, then m∠6=65 as well.

Have a nice day! :D
