Answer:

first graph option A

Step-by-step explanation:

Rule is y= 2x

Lets make a table to find out some point for graphing

Plug in some values for x and find out y

x y= 2x

-2 y=2(-2) = -4

0 y= 2(0)=0

2 y = 2(2)= 4

So the coordinates for graphing are (-2,-4) , (0,0) and (2,4)

The first graph has all the same coordinates .

So first graph represents the same relation

Answer:

82991 employees

Step-by-step explanation:

One way to solve this would be to solve for 1% of the company's employees and use that value to solve for 100% (100%=the whole part, or the total). We know that

28300 = 34.1%

If we divide a number by itself, it turns into 1. Dividing both sides by 34.1, we get

829.912 = 1%

Then, we know that anything multiplied by 1 is equal to itself. We want to figure out 100%, or the whole part, so we can multiply both sides by 100 to get

100% = 82991

If a number is added to the numerator of 7/8 and the same number is subtracted from the denominator, the result is 4. Find the n

Alisiya [41]

Answer:

The number is 5.

Step-by-step explanation:

Call the number n. Write the problem as an equation:

$\frac{7+n}{8-n}=4\\7+n=(8-n)4=32-4n\\5n = 25\\n=5$

The number is 5.

When karen serves jury duty, she will receive $15 each day for the first three days she serve. After three days, she will receiv

liubo4ka [24]

Karen received $ 213 for 10 days of serving

<em><u>Solution:</u></em>

Given that When karen serves jury duty, she will receive $15 each day for the first three days she serve

To find: money received by karen if she served for 10 days

First three days = $ 15 each day

Therefore,

first day = $ 15

second day = $ 15

third day = $ 15

After three days, she will receive $24 each day she serves

4th , 5th, 6th, 7th , 8th , 9th, 10th day = $ 24 each day

If she serves for 10 days,

money received = 15 + 15 + 15 + 24 + 24 + 24 + 24 + 24 + 24 + 24

money received = 3(15) + 7(24)

money received = 45 + 168 = 213

Thus karen received $ 213 for 10 days of serving

Integral of cosecx dx =log|tanx/2| show that.

Pie

ANSWER:

Let t = logtan[x/2]

⇒dt = 1/ tan[x/2] * sec² x/2 × ½ dx

⇒dt = 1/2 cos² x/2 × cot x/2dx

⇒dt = 1/2 * 1/ cos² x/2 × cosx/2 / sin x/2 dx

⇒dt = 1/2 cosx/2 / sin x/2 dx

⇒dt = 1/sinxdx

⇒dt = cosecxdx

Putting it in the integration we get,

∫cosecx / log tan(x/2)dx

= ∫dt/t

= log∣t∣+c

= log∣logtan x/2∣+c where t = logtan x/2
