Mathematics

lord [1]3 years ago
6 0

Answer:

That would be Option C.

Step-by-step explanation:

Lets look at y = 4x + 2:-

Let x = a then y = 4a + 2

Now if x in creases to a +2,  y = 4(a +2) + 2 = 4a + 8 + 2

= 4a + 10.

(4a + 10) - (4a + 2) = 8  ,  so this is the required expression, y = 4x + 2.

Find the value of x<br> A. 8 <br> B. 4<br> C. 19<br> D. 24
hodyreva [135]
<h3>Hello There!!</h3>

Given figure is a <u>parallelogram</u>

<u>To </u><u>Find</u>

Value of"x"

<h3><u>Solution</u></h3>

m \angle \: A = m \angle  \: C

2x + 35 = 5x - 22

\implies 2x - 5x =  - 22 - 35 \div  \\  \implies - 3x =  - 57 \\   \\ \implies x =  \frac{ - 57}{ - 3}  \\  \\  \implies  x =  \cancel\frac{ - 57}{ - 3} \\  \\  \implies x = 19

\therefore \text{Option C= 19 is the correct answer}

One year, Mr James travels 8 x 10^3 miles for his job. The next year he traveled 1 x 10^4 miles. How many more miles did he trav
nignag [31]

Answer:

2 000 miles

Step-by-step explanation:

In the first year, Mr James travels 8 x 10^{3} miles = 8 000 miles.

The second year, he traveled 1 x 10^{4} miles = 10 000 miles.

Comparing the distance covered in the two years,

10 000 miles - 8 000 miles = 2 000 miles

Therefore, Mr James travels 2 000 more miles in the second year than he did the first year.

Let's assume that Mr James conveys himself to his place of work all through the first year in his private car. But in the second year, there were some days in which the car was not available. So he had to go for his job by public transportation. This itch during those days, could cause an increase in the distance covered from his home to his place of work for the second year.

The marginal cost function of producing q mountain bikes is 600/0.3q+5.
wariber [46]
MArginal cost is the adjustment in all out cost that emerges when the amount created changes by one unit.(In another word subordinate of cost wrt unit) 
So we coordinate to get Cost work 
∫30 600/0.3q+5 (dq) 0
we get 9798.66 from joining. 
We add that to settle cost 2059.23+2200=4259.24 
So 4259.24 is the cost. 
Income from offering the bicycle is 205*30=6150 
and Profit=Revenue-Cost 
6150 - 4259.24=1890.76 
Presently Marginal Profit 
MArginal benefit is the term used to allude to the contrast between the minor cost the peripheral income for delivering one extra unit of creation. 
Marginal Profit=Marginal Revenue-Marginal Cost 
Marginal Cost=600/0.3q+5. 
We should connect to 31 to get 41.958 
Revenue= 205q 

Marginal rev=205 
Marginal Profit = 205-41.958=163.042
