Renee notices that her laptop is decreasing in value over time. She paid $1,160 for the laptop, and after 4years, she sees that

it is worth $740.
Find a linear function V(t) to model the value of the laptop as a function of t, where t is time in years.
Give your answer in the form V(t)=mt+b. Do not use a comma in any numbers.

Using the formula for slope, we can find out that (1160 - 740) \div (0 - 4) =  - 105 So -105 is the slope, and because she bought her laptop at $1160, the y-intercept is 1160. This means that the equation is V(t)=-105t+1160.

If f(x)=x-3, which inequality can be used to find the domain of f(x)?
Scrat [10]

Given that,

f(x) = \sqrt{x-3}

To find,

The domain of f(x).

Solution,

We have, f(x) = \sqrt{x-3}

To find domain,

The term under the square root must be positive or null as follows :

x-3\ge 0

Adding 3 both sides

x-3+3\ge 0+3\\\\x\ge 3

So, the domain is x-3>0 .

Work out these questions without a calculator and showing all working out

1) 6÷0.2 = 30

If 6/2=3 then 6/0.2=30 as the decimal place shifts one place.

2)8÷0.1 = 80

8/1=8 so shift the decimal place over once to make 80.

3)9÷0.3 = 30

9/3=3 so shift the decimal place over once to get 30.

4)4÷0.04 = 100

4/4=1 so shift the decimal place over twice to get 100.

5)7÷0.002 = 3500

7/2=3.5 so shift the decimal place over three times to get 3500

6)0.718÷0.2 = 3.59

718/2=359 so shift the decimal over three places for the 0.718 and then back over once for the 0.2

7)0.0141÷0.003 = 4.7

141/3=47 so shift the decimal over our times for the 0.0141 and then back over three times for the 0.003

8)0.24÷0.012 = 20

24/12=2 so shift the decimal point over once twice for 0.24 then back over three times for 0.012

9)1.625÷0.0013 = 1250

1625/13=125 so shift the decimal point over three times for the 1.625 and then back four times for the 0.0013

10)47.1÷0.15 = 314

471/15=31.4 so shift the decimal point over once for the 47.1 and then back over twice for the 0.15.

Hope this helps :)
