Is X-1 a factor of x^5-1?

Mathematics
1 answer:
Musya8 [376]2 years ago
4 0

Answer: No

Explanation:

According to factor theorem, if f(x)=0 then x is a factor of the given function or equation.

As x-1 is a factor

We equate x-1=0

x=1

Substituting in x^5-1, we have 1^5-1 =1-1=0.

Hence, it's a factor.

When coming to x^5+1, it would become 1^5+1=1+1=2

So x-1 isn't a factor of x^5+1.

Answer:

The fan = x = 400

The heater = y = 3600

Step-by-step explanation:

Let the cost price of

The fan = x

The heater = y

Aaya bought a fan and a heater for Rs 4,000.

x + y = 4000

x = 4000 - y

He sold the fan at a profit of 25%

25% × x = 0.25x

And the heater at a loss of 5%.

5% × x = 0.05y

If he gained 7% on his total outlay, at

Hence:

0.25x + 0.05y = 7% × 4,000

0.25x + 0.05y = 280

Note:

x = 4000 - y

Hence:

0.25(4000 - y) + 0.05y = 280

1000 - 0.25y + 0.05y = 280

Collect like terms

-0.25y + 0.05y = 280 - 1000

-0.20y = -720

y = -720/0.20

y = 3600

x = 4000 - y

x = 4000 - 3600

x = 400

Hence, the price that he bought each item is given as:

The fan = x = 400

The heater = y = 3600

A department store buys 100 shirts at a cost of ​$700 and sells them at a selling price of ​$10 each. Find the percent markup.
Serjik [45]

Answer:

42.8%

Step-by-step explanation:

Step one:

given data

A department store buys 100 shirts at a cost of ​$700

let us find the cost of 1 shirt

cost of 1 shirt= 700/100= $7 per shirt

The cost price per shirt = $7

We are given that the selling price = $10 per shirt

Step two:

The percent markup can be found as

percent markup= selling-cost price/cost price*100

percent markup= 10-7/10*100

percent markup= 3/7*100

percent markup= 0.428*100

percent markup= 42.8%

Given the number, two-fifths, generate its equivalent forms as a fraction, a decimal, and a percent. In addition, give a real wo
vichka [17]
The number in the three different forms is as follows.

2/5 (fraction), 0.2 (decimal), and 20% (percent).

You could use percentages for the results of a poll. For example, if you held a poll for which flavour of ice cream is your favorite. Let's say you surveyed 100 kids and 50 kids voted chocolate, 30 vanilla, and 20 strawberry. Then you could say 20% voted for strawberry. 

You could use the decimal form for money. For example, let's say you want to buy something that costs $10.20 and you only have 10 dollars. You could say that you would need 20 more cents, or $0.20.

As for the fraction, you could use this for measurements. For example, let's say you have a piece of fabric. You want to cut it up into 5 equal pieces, but only use two of those pieces. You could say that you would only use 2/5 of the fabric.

I hope I helped you out! If anything is wrong, please let me know about it! :)
