hram777 [196]
So, because the bike was 10% off, we know that the bike is now at 90% of its original value (100%-10% = 90%)
So to find the new value, we multiply the price by 90%:
0.9*206 = 185.4
The bike will cost Manuel $185.4

Solve for x over the real numbers using factor method:
10 x^2 + 19 x - 15 = 0

The left hand side factors into a product with two terms:
(2 x + 5) (5 x - 3) = 0

Split into two equations:
2 x + 5 = 0 or 5 x - 3 = 0

Subtract 5 from both sides:
2 x = -5 or 5 x - 3 = 0

Divide both sides by 2:
x = -5/2 or 5 x - 3 = 0

Add 3 to both sides:
x = -5/2 or 5 x = 3

Divide both sides by 5:

Answer:  x = -5/2 or x = 3/5

A bag has five red stones two green three blue six yellow and four purple stones what is the probability of choosing a yellow st
Y_Kistochka [10]

Answer:

Probability of picking yellow stones from the bag is 0.3.

Step-by-step explanation:

Given:

Number of red stone in bag = 5

Number of green stone in bag = 2

Number of blue stone in bag = 3

Number of yellow stone in bag = 6

Number of purple stone in bag = 4

We need to find the probability of choosing yellow stone from the bag.

Solution:

First we will find the Total number of stones in the bag.

Total number of stones in the bag is equal to sum of Number of red stone in bag ,Number of green stone in bag, Number of blue stone in bag, Number of yellow stone in bag and Number of purple stone in bag.

framing in equation form we get;

Total number of stones in the bag = 5+2+3+6+4 =20

Now Probability of picking yellow stones from the bag  can be calculated by  dividing Number of yellow stone in bag by Total number of stones in the bag.

framing in equation form we get;

P(Y) =\frac{6}{20}= 0.3

Hence Probability of picking yellow stones from the bag is 0.3.

(a) What is the actual cost incurred in producing the 1051st and the 2191st disc? (Round your answers to the nearest cent.)
Evgen [1.6K]

This question is incomplete, the complete question is;

The total weekly cost (in dollars) incurred by Lincoln Records in pressing x compact discs is given by the following function;

C(x) = 2000 + 2x -0.0001x²  (0 ≤ x ≤ 6000) .

(a) What is the actual cost incurred in producing the 1051st and the 2191st disc? (Round your answers to the nearest cent.)

(b) What is the marginal cost when x = 1050 and 2190? (Round your answers to the nearest cent.)

Answer:

a)

Actual cost for 1051st disc is $1.79

Actual cost for 2191st disc is $1.56

b)

the marginal cost are;

C'(1050) = $1.79

C'(2190) =  $1.56

Step-by-step explanation:

Given the data in the question;

C(x) = 2000 + 2x -0.0001x²

a)

What is the actual cost incurred in producing the 1051st and the 2191st disc? (Round your answers to the nearest cent.)

Actual cost for 1051st disc will be;

⇒ C(1051) - C(1050)  

= [ 2000 + 2(1051) - 0.0001×(1051)²] - [ 2000 + 2(1050) - 0.0001×(1050)² ]

= [ 2000 + 2102 - 110.4601 ] - [ 2000 + 2100 - 110.25 =

= 3991.5399 - 3989.75

= $ 1.7899 ≈ $1.79

Actual cost for 2191st disc will be;

⇒ C(2191) - C(2190)  

= [ 2000 + 2(2191) - 0.0001×(2191)²] - [ 2000 + 2(2190) - 0.0001×(2190)² ]

= [ 2000 + 4382 - 480.0481 ] - [ 2000 + 4380 - 479.61 ]

= 5901.9519 - 5900.39

= $ 1.5619 ≈ $1.56

Therefore,

Actual cost for 1051st disc is $1.79

Actual cost for 2191st disc is $1.56

b)

What is the marginal cost when x = 1050 and 2190? (Round your answers to the nearest cent.)

Marginal cost is; C'(x) = 2 - 0.0002x

so;

C'(1050) = 2 - 0.0002(1050) = 2 - 0.21 = $1.79

C'(2190) = 2 - 0.0002(2190) = 2 - 0.438 = $1.562 ≈ $1.56

Therefore; the marginal cost is;

C'(1050) = $1.79

C'(2190) =  $1.56
