Answer:

A Farmhouse shelters 10 animals. some are pigs and some are ducks. Altogether there are 36 legs. How many of each animal are there? Answer: 8 pigs and 2 ducks.

1. (A) p + d = 10

2. (B) 4p + 2d = 36

3. Multiply equation (A) with -2; -2p minus -2d = -20

4. When subtracted from equation (B), this gives you.. 2p = 16, pigs = 8

5. Use this 8 to the second equation by substitution.. 2d = 4, ducks = 2

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))

Final answer:

The marginal-cost function c'(x) is 9.

Explanation:

Marginal-cost function:

Given cost function: C(x) = 800 + 400 + 10x - x

Find derivative of C(x): C'(x) = 10 - 1 = 9

Therefore, the marginal-cost function is c'(x) = 9

Answer:

37 Degrees

Step-by-step explanation:

Manipulate the triangle so angle A measures approximately 92°.

Manipulate the triangle so angle B measures approximately 51°.

Notice the straight line p.

What must the measurement of angle C be for p to remain a straight line?

Angle C should measure approximately 37 Degrees

There is angle C should measure approximately 37° for line p to remain a straight line.

When two lines intersect at a location, vertical angles are generated. They are always equal to each other.

As we know that a straight line, the sum of the angles is equal to 180°.

So, when angle A measures approximately 92° and angle B measures approximately 51°,

Then, the measurement of angle C must be 180° - 92° - 51° = 37° in order to keep line p a straight line.

Thus, angle C should measure approximately 37° for line p to remain a straight line.

Answer:

a The minimum of h(x) is farther left and up than the minimum of f(x) and g(x)

Step-by-step explanation:

To know the relation between the minima of the functions you calculate the minima by using the derivative:

[tex]f'(x)=2x\\\\g'(x)=2(x+1)\\\\h'(x)=2(x+3)[/tex]

to find the values of x you equal the derivative of the function to zero:

[tex]f'(x)=0;\ x=0;\\\\g'(x)=0; \ x=-1;\\\\h'(x)=0;\ x=-3;[/tex]

by evaluating this values of x you obtain the coordinates of the minima:

[tex]f(0)=0\\\\g(-1)=-2\\\\h(-3)=4[/tex]

hence, the coordinates will be:

f -> (0,0)

g -> (-1,-2)

h -> (-3,4)

hence, the relation is:

a The minimum of h(x) is farther left and up than the minimum of f(x) and g(x).

Answer:

105 degrees

Step-by-step explanation:

The sum of the angles in a triangle add up to 180. Although we don't the know the numerical values of the angles, we can create an equation with the given expressions:

<P + <Q + <R = 180

(6x + 5) + (11x - 5) + x = 180

18x = 180

x = 10

Now, plug this value of x into the expression for Q:

<Q = 11x - 5 = 11 * 10 - 5 = 110 - 5 = 105

Thus, the measure of angle Q is 105 degrees.

Hope this helps!

Answer:

105 degrees

Step-by-step explanation:

The angles in a triangle must add to 180 degrees

<Q +<P + <R =180

We know <Q is 11x-5, <P is 6x+5 and <R is x, so we can substitute them in

11x-5+6x+5+x=180

Combine like terms

11x+6x+x +5 -5 =180

18x=180

Divide both sides by 18

x=10

Now we know x, and we can substitute that in to to find <Q

<Q=11x-5

<Q=11(10)-5

<Q=110-5

<Q=105

Answer:

The final price with tax is 15,921.75‬, and the total tax added was 971.75‬

Step-by-step explanation:

To find the final cost, you multiply the cost of the product by the tax rate plus one.

For this problem, you multiply 14,950 by (0.065 + 1) to get the answer

Answer:

$15,921.75

Step-by-step explanation:

1. Multiply the cost of the car by the sales tax rate.

14950*.65= 971.75

2. Then add this amout to the original cost of the car.

14950 + 971.75= $15,921.15

b) The numbers of straws in each diagram are ...

c) Each term is 5 more than the previous one, so the recursive rule for the number of straws is ...

  s[n] = s[n-1] +5

__

d) The next three terms of the sequence are ...

  ..., 26, 31, 36, ...

Answer:

Well, if you substitute 2 and 6 on the first expression, the answer you get when x=2 is half of what you get when x=6

But for the second expression, the answers are not equivalent

Answer:

If both expressions have the same value after substituting and simplifying for x = 6 and x = 2, then they are equivalent. The value of both expressions is 15 when x = 6. The value of both expressions is 7 when x = 2. So, the expressions are equivalent

Answer:

47.1

Step-by-step explanation:

Sorry if its wrong

The cone's volume is approximately 47.1 cubic centimeters, obtained by rotating the provided isosceles triangle along its central blue axis.

The volume of a cone is calculated by the following formula:

[tex]$V = \frac{1}{3}\pi r^2 h$[/tex]

where r is the radius of the base and h is the height of the cone.

In this case, the height is simply the height of the triangle, which is 5 cm.

The radius is a bit trickier.  

Notice that the blue dashed line bisects the base of the triangle.  Therefore, the radius is half the length of the base, which is 6 cm / 2 = 3 cm.

Substituting these values into the formula, we get:

[tex]$V = \frac{1}{3}\pi (3\text{ cm})^2 (5\text{ cm})$[/tex]

[tex]$V = 15\pi \text{ cm}^3$[/tex]

Rounding this to the nearest tenth, we get:

[tex]$V = 47.1 \text{ cm}^3$[/tex]

Therefore, the volume of the cone is approximately 47.1 cubic centimeters.

b. 255

Step-by-step explanation:

The maximum Error E is 1.3

approximately normal test scores,

Standard Deviation, SD is 6.5

a).

Level of confidence = 99.7%

critical value of z for a two tailed test and 0.3% level of significance is 3

since the sample mean is within 0.5 of the true population mean

hence, the standard dev of mean is given by

[tex]Z_{\alpha}[\frac{\sigma}{\sqrt{n}} ]=E[/tex]

where E = 1.3

[tex]Z_{\alpha}=[/tex] 1.3

[tex]\frac{\sigma}{\sqrt{n}} =\frac{E}{Z_{\alpha}} \\\\\frac{\sigma}{\sqrt{n}} =\frac{1.3}{3}[/tex]

hence the Std of the mean is 0.4333 (to 4 d.p.)

b).

The sample size is computed as follows

making n the subject of formular of the above equation

[tex]\sqrt{n} =\frac{3\sigma}{1.3}} \\\\\sqrt{n} =\frac{3\times 6.5}{1.3}} \\\\n=(\frac{3\times 6.5}{1.3}})^2[/tex]

hence,

Answer: B

Step-by-step explanation:

X axis only

The graph of r = -3 + 5cosθ is symmetric about the option (B) x axis only

In mathematics, symmetry has a more precise definition, and is usually used to refer to an object that is invariant under some transformations; including translation, reflection, rotation or scaling.

A graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense related.

Here,

The graph of r = -3 + 5cosθ is symmetric about the x axis only

Also when we plot the graph we can say that it is symmetric about x axis only.

Hence, the graph of r = -3 + 5cosθ is symmetric about the option (B) x axis only
