if a<b<0 show that a² > b²

PLEASE SHOW STEP-BY-STEP​

Answers

Answer 1

Answer:

a2−b2=(a−b)(a+b).

Since a≥0 and b>0, a+b>0 and a−b<0 since a<b, thus: (a−b)(a+b)<0. So a2−b2<0. Thus a2<b2.

If ST=w–47 and RU=w–63, what is the value of w?

Answers

Answer:

w = 79

Step-by-step explanation:

We know that RU us a midsegment so it must be 1/2 of ST.

So ST = 2RU.

w-47 = 2(w-63)

w-47 = 2w-126

-w = -79

w = 79

Step-by-step explanation:

1 is 90 because it's placed onto a straight line the equals 180 degrees, therefore it's 90 because the other 2 angles with it are the same, meaning that they had to be 45. 3 is 55 because 90+35=125, and the sum of all 3 angles in a triangle must equal 180, therefore 180-125=55.

A recipe says to use 3.5 cups of flour to make 48 cookies. What is the constant of proportionality that relates the number of cookies made, y, to the number of cups of flour used, x. Round your answer to the nearest tenth.

Answers

Answer: 0.07 cups/cookie

Step-by-step explanation:

The Constant of proportionality is the measure by which the number of cookies made, y increases to the number of cups of flour used, x.

If 3.5 cups of flour makes 48 cookies then how many cookies does 1 cup make;

= 3.5/48

= 0.07 cups/cookie

Given:

To find:

The relation which is not a function.

Step-by-step explanation:

A relation is called function if there exist unique output for each input.

It means, each x-value has only one y-value.

{(1, 3), (3, 7), (5, 11), (7, 15), (9, 19)}, it is a function.

{(1, 3), (1, 7), (5, 11), (5, 15), (9, 19)}, it is not a function because there exist two y-values y=3 and y=7 at x=1.

{(−2, 4), (−1, 1), (0, 0), (1, 1), (2, 4)}, it is a function.

{(2, 4), (1, 1), (0, 0), (1,−1), (2, −4)},it is not a function because there exist two y-values y=4 and y=-4 at x=2.

{(6, 3), (4, 1), (2, 1), (0,−1), (−2,−3)}, it is a function.

{(1, 3), (3, 7), (3, 11), (7, 15), (9, 19)}, it is not a function because there exist two y-values y=7 and y=11 at x=3.

{(1, 3), (3, 7), (5, 11), (9, 15), (9, 19)}, it is not a function because there exist two y-values y=15 and y=19 at x=9.

Therefore, the correct options are 2, 4, 6 and 7.

A company that uses job order costing reports the following information. Overhead is applied at the rate of 60% of direct materials. The company has no beginning Work in Process or Finished Goods inventories. Jobs 1 and 3 are not finished by the end of March, and Job 2 is finished but not sold by the end of March

Answers

Based on the percentage completed and the cost of the jobs, total value of work in process inventory at the end of March is $62,480.

What is the Work in Process Inventory?

The work in process will include Jobs 1 and 3 only because job 2 is already done.

Work in process can be found as:

= Cost of job 1 + Cost of job 3

Cost of a single job is:

= Direct labor + Direct materials + Overhead which is 60% of direct materials

Solving for both jobs gives:

= (13,400 + 21,400 + (13,400 x 60%)) + (6,400 + 9,400 + (6,400 x 60%))

= $62,480
