A new computer loses 1/2 of its value every year. Which graph could represent the relationship between the year and the computer

Igoryamba

Let's first consider: the fact that a new computer loses 1/2 of its value

⇒ third choice and fourth choice are eliminated

⇒ because of the graph project the computer's value as growing over

years

Now let's try to set up an equation:

After 1st year ⇒ Computer's value = $total_.value*\frac{1}{2}$

After 2nd year ⇒ Computer's value = $total_.value*\frac{1}{2}*\frac{1}{2}=total_.value*(\frac{1}{2} )^2$

After 3rd year ⇒ Computer's value = $total_.value*\frac{1}{2}*\frac{1}{2}* \frac{1}{2}=total_.value*(\frac{1}{2})^3$

..... (Hopefully you see a pattern)

After x year ⇒ Computer's value = $total_.value*(\frac{1}{2})^x$

Therefore, the equation is: $total_.value*(\frac{1}{2})^x$

⇒that means the graph has to exponentially decreasing as it has

an exponent (meaning the function is exponential) and a base less

than 1 (meaning that the function is decreasing)

Answer: Choice (1)

Hope that helps!

How can two different rectangles both have a perimeter of 24 cm

dem82 [27]

Explanation:

Perimeter is simply the sum of all the edges. The same way 10 can be made of 4+6 or 3+7, the perimeter can be made by many combinations. if you know the 2 must equal 24cm, then we can create numerous combinations.

I need help plz and thanks

Ganezh [65]

For both of these questions, we have to use PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. This is the order that we need to do things.

1.)

(1 x 2) x 3^2 x 4 + 5

Parentheses - multiplication

2 x 3^2 x 4 + 5

Exponents

2 x 9 x 4 + 5

Multiplication

72 + 5

Addition

77

2.)

8 + 6 x 3 x 4 x 8

Multiplication

8 + 576

Addition

584
