Which choice provides the best evidence for the

Mathematics
1 answer:
vodka [1.7K]2 years ago
6 0

Correct option is B, Lines 39-42 ("Normally . . . community")

The "matter of urgency," as Akira explains in lines 39–42, is that he has "an opportunity to go to America, as dentist for Seattle's Japanese community." Chie's response to Akira's marriage proposal is necessary for him to determine whether or not to take the position in Seattle.

The answers to the previous question are not well supported by the evidence in Choices A, C, and D. Choice A is wrong since Akira apologizes for disturbing Chie's peaceful evening in line 39. Lines 58–59 discuss the gravity of Akira's demand, not its immediacy, hence option C is incorrect.

Line 73 merely demonstrates that Akira's suggestion "startled" Chie, not why his request is time-sensitive, hence option D is incorrect.

Here's another question with an answer similar to this Chie and Akira:

Find the zeros of the polynomial p(x) 5-10x​
Charra [1.4K]

Answer:

Step-by-step explanation:

The given polynomial is :

p(x) = 5-10x​

We need to find the zeros of the above polynomial. To find it, put p(x) = 0

5-10x​ = 0

Subtract 5 from both sides

5-10x​-5=0-5

-10x=-5

or

10x=5

Divide both sides by 10.

x = 0.5 = 1/2

Hence, the zeros of the polynomial is 1/2.

During one month, a homeowner used 500 units of electricity and 100 units of gas for a total cost of $333. The next month, 400 u
Mice21 [21]

Answer: the cost per unit of gas is $0.28

Step-by-step explanation:

Let x represent the cost per unit of electricity.

Let y represent the cost per unit of gas.

During one month, a homeowner used 500 units of electricity and 100 units of gas for a total cost of $333. This is expressed as

500x + 100y = 333 - - - -- - -- - -- -1

The next month, 400 units of electricity and 150 units of gas were used for a total cost of $286. This is expressed as

400x + 150y = 286 - - - - - - - - - --2

Multiplying equation 1 by 400 and equation 2 by 500, it becomes

200000x + 40000y = 133200

200000x + 75000y = 143000

Subtracting, it becomes

- 35000y = - 9800

y = - 9800/- 35000

y = 0.28

Substituting y = 0.28 into equation 2, it becomes

400x + 150 × 0.28 = 286

400x = 286 - 42 = 244

x = 244/400 = 0.61

It takes Brian 15 hours longer to build a model car than it takes John. If they work together, they can build the model car in 4
Tatiana [17]
    When they work together, it takes John 1/x hours and it takes Brian 1/(x+15) hours to complete 1/4 of the model.
   1/x + 1/( x+15 ) = 1/4  / · x ( x+15 )
    x+15 + x = x ( x+15 ) /4      / · 4
    8 x + 60 = x² + 15 x
    x² + 15 x - 8 x - 60 = 0
    x² + 7 x - 60 = 0
    x² + 12 x - 5 x - 60 = 0
    x · ( x + 12 ) - 5 ·( x+ 12 ) = 0
    ( x + 12 ) · ( x - 5 ) =0
    x = - 12  ( not accepted ) or  x = 5
    The time taken by Brian:  5 + 15 = 20 hours

Simplify (x^4-9x+5x^7)+(5x-10+3x^4-2x^2)
Nadya [2.5K]

Answer:

5x^7 + 4x^4 - 2x^2 - 4x - 10.

Step-by-step explanation:

(x^4 - 9x + 5x^7) + (5x - 10 + 3x^4 - 2x^2)

= x^4 - 9x + 5x^7 + 5x - 10 + 3x^4 - 2x^2

Combine like terms:

= 4x^4 - 4x - 2x^2 + 5x^7 - 10

Now rearrange to standard form ( in decreasing degree):

= 5x^7 + 4x^4 - 2x^2 - 4x - 10.
