Answer:

y = -1/2 ( x − 4 )^2 + 8

Step-by-step explanation:

First find the vertex form

y = a ( x − h )^ 2 + k where ( h,k) is the vertex

The vertex is ( 4,8)

y = a ( x − 4 )^2 + 8

Now we need to determine a

Pick a point on the graph (0,0)

and substitute this point into the equation

0 = a ( 0 − 4 )^2 + 8

0 = a (16) +8

-8 = 16a

-8/16 =a

-1/2

y = -1/2 ( x − 4 )^2 + 8

David charges $4 to wash all the windows of a car, inside and out. The amount of money he earns washing the windows must end in

nordsb [41]

Answer:

The possible digits are : 0, 2, 6, 4, 8

Step-by-step explanation:

Money charged by David to wash the windows of a car = $4

Let total number of cars he washed be x

Now, Total money earned by washing windows of a car = Money charged for washing all windows of one car × Total number of cars washed

⇒ Total money earned = 4 × x

So, the amount will always end in the digits which comes at the end of multiples of 4 because the amount will be always in the multiples of 4

⇒ 4 × 1 = 4 , 4 × 2 = 8 , 4 × 3 = 12 , 4 × 4 = 16 , 4 × 5 = 20 ......

So, the possible digits are : 0, 2, 6, 4, 8

grin007 [14]

The question is incomplete:

If you see that gasoline costs $1.70 in Georgia and $3.40 in California, you can conclude that gasoline is twice as expensive in California as in Georgia. This conclusion from this comparison reflects the function of money as a:

-store of value

-an object with a value that varies sharply from one place to another

-medium of exchange

-unit of account

Answer:

Unit of account

Step-by-step explanation:

-Store of value refers to something that can be kept for a period of time and maintains its value in the future.

-An object with a value that varies sharply from one place to another means that products can have different prices in different places.

-Medium of exchange refers to an object with an standard value that allows you to purchase goods or services.

-Unit of account refers to a numerical unit that allows you to compare the value of products and services.

According to this, the answer is that this conclusion from this comparison reflects the function of money as a unit of account because it indicates that money works as a unit that you can use to compare the value of products, in this case the price of gasoline in different places.
