The price of a computer component is decreasing at a rate of ​10% per year. State whether this decrease is linear or exponential. If the component costs ​$ 110 today, what will it cost in three​ years?

Answers

Answer:

The cost in 3 years is $80.19.

Step-by-step explanation:

The cost of computer component is $110 today.

The cost is decreasing at a rate of 10% per year.

When it decreases by 10% per year then it is exponential.

Initial cost is $110. When it decreases 10% per year, the decay factor is 1-0.10 =0.90.

So, we could use the exponential formula y=[tex]ab^{x}[/tex]

Where 'a' is initial cost and b is decay factor.

Our equation would by plug in 'a' as 110 and 'b' as 0.90.

We get

[tex]y= 110(0.9)^{x}[/tex]

Now, to find the cost in 3 years, use x as 3.

[tex]y=110(0.9)^{3}[/tex]

Which is simplified to

y=$80.19

A company's profits for a week are as follows:
Monday: +$32.65, Tuesday: -$75.32,
Wednesday: -$125.75, Thursday: +$100.89,
and Friday: +$65.30. Does the company show
a gain or loss at the end of the week?

Answers

Answer:

Loss

Step-by-step explanation:

If you add all the numbers up you get -2.23 which would be a loss

Answer:

The company shows loss

Step-by-step explanation:

32.65 - 75.32= -42.67 so they're already at a loss

you would add -125.75 and -42.67 and woud get -168.42

Then you would add 100.89 and 65.30 and you would get 166.19

166.19+(-168.42)=-2.23

The answer is 10

Answers

Answer:

x = 10

Step-by-step explanation:

Since ΔCDE ~ ΔQRS, we can find the actual length of x + 8 first before finding the value of x.

Length of x + 8 = [tex]\frac{12}{20}[/tex] × 30

                         = 18

x + 8 = 18

x = 18 - 8

x = 10
