The total cost to produce x handcrafted wagons is C(x) = 110 + 7x - x^2 + 2x^3. Find the marginal cost when x = 8.

nataly862011 [7]

<h2>Answer:</h2>

The marginal cost when x=8 is:

375

<h2>Step-by-step explanation:</h2>

We know that the marginal function for a cost function C(x) at x=a

is given by:

C'(x) at x=a

Here we have the cost function C(x) as:

$C(x)=110+7x-x^2+2x^3$

Now we find the derivative of C(x) with respect to x.

i.e.

$C'(x)=0+7-2x+6x^2$

( Since,

$\dfrac{d}{dx} x^n=nx^{n-1}$ )

$C'(x)=7-2x+6x^2$

Hence, we get:

$C'(8)=7-2\times 8+6\times (8)^2\\\\i.e.\\\\C'(8)=7-16+384\\\\C'(8)=375$

PSYCHO15rus [73]

Answer:

(I). 20.03:

$= 2.003 \times {10}^{1}$

(ii). 200.03

$= 2.0003 \times {10}^{2}$

(iii). 2.034

$= 2.034 \times {10}^{0}$

What is the fiftieth term in the sequence 5, 7, 9, 11, 13 …?

Komok [63]

The 15th term in the given A.P. sequence is a₁₅ = 33.

According to the statement

we have given that the A.P. Series with the a = 5 and the d is 2.

And we have to find the 15th term of the sequence.

So, for this purpose we know that the

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

And the formula is a

an = a + (n-1)d

After substitute the values in it the equation become

an = 5 + (15-1)2

a₁₅ = 5 + 28

Now the 15th term is a₁₅ = 33.

So, The 15th term in the given A.P. sequence is a₁₅ = 33.

Help me and you get 100 points and Brainliest

OlgaM077 [116]

hey someone else has already answered this!

a. To find the least squares regression equation for a group of (x,y) points:

Step 1: For each point(x,y), we need to calculate x² and xy first.

Step 2: Sum all x, y, x² and xy, which gives us Σx, Σy, Σx² and Σxy

Step 3: Calculate Slope m: m = (NΣxy − Σx Σy)/ N(Σx²) − (Σx)² , here N is the number of data.

Step 4: Calculate Intercept b: b = Σy − m(Σx)/ N

Step 5: Assemble the equation as y= mx+b

Here, we have ∑x = 120, ∑y= 1379, ∑x²= 919.5, ∑xy= 10466 and N= 16

So, m= (NΣxy − Σx Σy)/ N(Σx²) − (Σx)²

= 6.33

and b = Σy − m(Σx)/ N

= 38.71

So, the least squares regression equation is : y= mx+b ⇒ y= 6.33x +38.71

b. When x= 8, then y= (6.33×8)+38.71 = 50.64 + 38.71 =89.35

The approximate test score of a student who sleeps an average of 8 h a night is 89.35%
