Suppose the function, g(x), is used to model the height ,y, of a soccer ball, x seconds after the ball is kicked up in the air.

The ball starts on the ground and travels in a parabolic shape as it reaches a maximum height and then returns to the ground. Suppose further that the ball reaches its maximum height of 15 feet in 2.2 seconds. What would be an appropriate domain for g(x)?

the ball reaches its maximum height of 15 feet in 2.2 seconds

The ball starts on the ground and travels in a parabolic shape as it reaches a maximum height and then returns to the ground

The ball starts on the ground at 0 seconds so the ball starts at x=0 seconds

the ball reaches its maximum height of 15 feet in 2.2 seconds

So it takes 2.2 second to reach the maximum height

It will take another 2.2 seconds to reach the ground

The time the ball in the air is 2.2 + 2.2 = 4.4

The ball will reach the ground in 4.4 seconds

So the domain for g(x) is {0,4.4}

The ratio of backslappers to wallflowers at the political convention was 20 to I. If there were 460 backslappers, how many wallf
Alja [10]

Answer:

x =23

Step-by-step explanation:

We can use a ratio to solve

20 backslappers        460 backslappers

------------------------- = ------------------------------

1 wallflower                    x wallflowers

Using cross products

20*x = 460*1

Divide each side by 20

20x/20 = 460/20

x =23

Bumek [7]

Sara's score would be 56.

<h3 /><h3>Examining the dart board</h3>

Looking at the dartboard, the point that is attached to the target is 9 points. This means that every time Sara hits the target, she earns 9 points.

<h3>Determining the total score </h3>

The score can be determined by multiplying the number of darts hit by the score attached to the target.

9 x 6 = 54 points

Presented below are the components in determining cost of goods sold. Determine the missing amounts.
vitfil [10]

Answer:

a) $190,000

b) $70,000

c) $65,000

d) $81,000

e) $60,000

f) $133,000

Step-by-step explanation:

Please refer to the attached table where known and unknowns are given as per question.

(a) Costs of Goods available for sale:

The amount of cost of goods available for sale is calculated by adding the purchases and beginning inventory.

Costs of Goods available for sale = Beginning Inventory + Purchases

Costs of Goods available for sale = $80,000 + $110,000

Costs of Goods available for sale = $190,000

(b) Ending Inventory:

The amount of ending inventory is calculated by subtracting the cost of goods sold from the costs of goods available for sale.

Ending Inventory = costs of goods available for sale - cost of goods sold

Ending Inventory = $190,000 - $120,000

Ending Inventory = $70,000

(c) Purchases:

The amount of purchases is calculated by subtracting the beginning inventory from the cost of goods available for sale.

Purchases = costs of goods available for sale - beginning inventory

Purchases = $114,000 - $49,000

Purchases = $65,000

(d) Cost of Goods sold:

The amount of cost of goods sold is calculated by subtracting the ending inventory from the cost of goods available for sale.

Cost of Goods sold = costs of goods available for sale - ending inventory

Cost of Goods sold = $114,000 - $33,000

Cost of Goods sold = $81,000

(e) Beginning Inventory:

The amount of beginning inventory is calculated by subtracting  the purchases from the cost of goods available for sale.

Beginning Inventory = costs of goods available for sale - Purchases

Beginning Inventory = $160,000  - $100,000  

Beginning Inventory = $60,000

(f) Cost of Goods sold:

The amount of cost of goods sold is calculated by subtracting the ending inventory from the cost of goods available for sale.

Cost of Goods sold = costs of goods available for sale - ending inventory

Cost of Goods sold = $160,000 - $27,000

Cost of Goods sold = $133,000
