Answer:

8,567

Step-by-step explanation:

Given the cost function expressed as C(x)=0.7x^2- 462 x + 84,797

To get the minimum vaklue of the function, we need to get the value of x first.

At minimum value, x = -b/2a

From the equation, a = 0.7 and b = -462

x = -(-462)/2(0.7)

x = 462/1.4

x = 330

To get the minimum cost function, we will substitute x = 330 into the function C(x)

C(x)=0.7x^2- 462 x + 84,797

C(330)=0.7(330)^2- 462 (330)+ 84,797

C(330)= 76230- 152460+ 84,797

C(330) = 8,567

Hence the minimum unit cost is 8,567

The minimum unit cost for producing each car is $8567

Cost is the amount of money spent in producing a particular number of items.

Let C(x) represent the cost in dollar to produce x number of cars. Given that:

C(x)=0.7x² - 462x + 84797

The minimum cost is at C'(x) = 0. Hence:

C'(x) = 1.4x - 462

1.4x = 462

x = 330

The minimum cost is when 330 cars are produced, hence:

C(330) = 0.7(330)² - 462(330) + 84797 = 8567

The minimum unit cost is $8567

Answer:

The number would have to be added is 9

Step-by-step explanation:

To find the form of the completing square of the quadratic function:

Let us do these steps with our question

∵ x² + 10x + 16 = 0

→ Divide the coefficient of x by 2

∵ The coefficient of x is 10

∴ 10 ÷ 2 = 5

→ Square the 5

∵ (5)² = 25

→ Subtract the numerical term from 25

∵ The numerical term = 16

∵ 25 - 16 = 9

∴ We must add 9 to 16 to get 25

→ (x² + 10x + 16 + 9) - 9 = 0

→ (x² + 10x + 25) = 9

→ (x + 5)² = 9

The number would have to be added is 9

Answer:

Step-by-step explanation:

Since the triangles are similar, we can use ratios to solve

12        ?

----- = -------

3         5

Using cross product

12*5 = 3?

60 = 3?

Divide each side by 3

60/3 = 3?/3

20 = ?

The unknown side is 20

Answer:

20

Step-by-step explanation:

Since the triangles are similar, all the side lengths can be multiplied by a scale factor,

12/3 = 4, so the scale factor is 4, which

5 x 4 = 20, so the missing side length is 20

Answer:

Yes

Step-by-step explanation:

Step 1: Define

12x - 10x⁵ - 7 + 3x⁴

-10x⁵ + 3x⁴ + 12x - 7

Step 2: Rearrange both equations into standard form

-10x⁵ + 3x⁴ + 12x - 7

-10x⁵ + 3x⁴ + 12x - 7

We see both are equivalent.

controling identifying the problem to be solved, determine the relevant information, and choose how they solve the problem. When students are given the opportunity to make choices in their classwork, they are more invested.

The function is also defined at x = 0 thus the domain is all real numbers and the range is y ≥ 0 thus option (b) is correct.

A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.

The domain is for the independent variable while the range is for the dependent variable.

As per the given graph.

The graph is the function of y = |x|

At x = 0 , y = 0 (defined)

And the function goes x = -∞ to ∞

Hence "The function is also defined at x = 0 thus the domain is all real numbers and the range is y ≥ 0".

Answer:

L = 37 yards and B = 76 yards

L = 38 yards and B = 76 yards

Step-by-step explanation:

Given:

Total length of the fence(perimeter) = 150 yards

One side is fenced using the back side of the house

So, we have

Perimeter of the fence = 2L + W

150 = 2L + W (1)

The fenced-in portion = 2,812 square yards

Area of a rectangle = L × W

2812 = L × W (2)

From (1)

150 = 2L + W

W = 150 - 2L

Substitute W = 150 - 2L into (2)

2,812 = L × W (2)

2,812 = L × (150 - 2L)

2,812 = 150L - 2L²

-2L² + 150L - 2812 = 0

2L² - 150L + 2812 = 0

Divide through by 2

L² - 75L + 1406 = 0

Solve the quadratic equation using factorization method

Find the factors

L² - 37L - 38L + 1406 = 0

L ( L - 37 ) - 38 ( L - 37 ) = 0

( L - 37 ) ( L -38 ) = 0

L - 37 = 0 or L - 38 = 0

L = 37 yards or L = 38 yards

If L = 37 yards

B = 150 - 2L

B = 150 - (2 × 37)

= 150 - 74

= 76 yards

If L = 38 yards

B = 150 - 2L

B = 150 - (2 × 38)

= 150 - 76

= 74 yards

Therefore,

The dimensions of the fence can either be

L = 37 yards and B = 76 yards

L = 38 yards and B = 76 yards

Answer:

9) 25 is the hypotenuse so it should be replaced with c, not a or b.

10) 6.5 feet

Step-by-step explanation:

9) The pythagorean theorem is [tex]a^2+b^2=c^2[/tex].

The pythagorean theorem says that c MUST always be the hypotenuse length. The hypotenuse side can be identified because it is always on the opposite side of the right angle and the diagonal one (and of course the longest side).

a and b can be any other side except for c. What they did wrong was that they put the hypotenuse side as b.

Now to correct the error

[tex]a^2+b^2=c^2\\7^2+b^2=25^2\\49+b^2=625\\49+b^2-49=625-49\\b^2=576\\[/tex]

[tex]\sqrt{b^2}=\sqrt{576} \\b=24[/tex]

The missing side length is 24.

10)  The question is asking for the c length (which is the hypotenuse). Use pythagorean theorem to solve for c.

[tex]a^2+b^2=c^2\\5.6^2+3.3^2=c^2\\42.25=c^2\\\sqrt{42.25}=\sqrt{c^2}\\6.5=c[/tex]

The length of the wire is 6.5 feet.
