Answer: 24oz - $2.59

Step-by-step explanation: 3.29/32= 0.1028

2.59/24= 0.1079

The value of a and b are 11 and 14.

The equation on a graph shows the point where the equation intersects

on the x-axis and the y-axis.

We have,

The function as y = 2x² + ax + b

Where it intersects on the x-axis at the points (-7/2, 0) and (2, 0).

Now we can write it as:

At point (-7/2, 0).

0 = 2 (-7/2)² + a(-7/2) + b

0 = 49 / 2 - 7a/2 + b

7a/2 - b = 49/2 _____(1)

At point (2, 0)

0 = 2(2)² + 2a + b

0 = 8 + 2a + b

2a + b = -8 _____(2)

From (1) and (2) we can find a and b.

From (1)

7a/2 - 49/2 = b

b = (7a - 49) / 2 ______(3)

putting in (2)

2a + (7a - 49) / 2 = -8

4a + 7a - 49 = -16

3a - 49 = -16

3a = -16 + 49

3a = 33

a = 11

putting in (3)

b = (7x11 - 49) / 2

b = (77 - 49) / 2

b = 28 / 2 = 14

Thus the value of a and b are 11 and 14.

The value of a and b for the given equation is 3 and -14 respectively.

The given equation is y=2x²+ax+b, (-7/2, 0) and (2, 0).

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Now put (-7/2, 0) and (2, 0) in the given equation and find a and b value.

That is, 0=2 (-7/2)²+a(-7/2)+b

⇒ 49/2 -7a/2+b=0 ----(I)

0=2(2)²+a(2)+b

⇒ 8+2a+b=0

⇒ b=-2a-8 -----(II)

Put b=-2a-8 in equation (I) and simplify.

That is, 49/2 - 7a/2 -2a-8=0

⇒ 49/2 - 11a/2 - 8 =0

⇒ 49 - 11a=16

⇒ 11a=33

⇒ a=3

Put a=3 in equation (II) and simplify.

That is, b=-2(3)-8=-14

Therefore, the value of a and b for the given equation is 3 and -14 respectively.

Answer:

500 ft

Step-by-step explanation:

use this formula

The actual distance between first and second ride is 500 ft.

The distance between two point P(a, b) and Q(c, d).

so, the distance PQ = √(c-a)² + (d- b)²

Given:

Starting point = (0,0)

First ride = (0,4)

Second ride = (3,0)

In map, each unit = 100 ft

Using the distance formula

d =  √( 3-0)² + (0-4)²

d = √9+ 16

d= √25

d = 5 units

So, the distance between first ride and second ride in the map is 5 units.

and,1 units  = 100 ft

5 units = 500 ft

Hence, the actual distance between first and second ride is 500 ft.

Answer: 100oz=6.25 lb

Step-by-step explanation:

The total money Ani raised was  217 dollars.

Cost price of soda = 310 dollars

money raised = selling price - cost price

What is selling price?

The cost at which something is sold. Calculate the total cost of all the items you bought. To calculate the cost price, divide the total cost by the quantity of units purchased. Use the selling price formula to calculate the final price: Cost price plus profit margin equals selling price.

What is cost price ?

Cost price is the complete sum of money that a manufacturer must spend to create a specific good or render a specific service. Cost is equal to Selling price plus Loss ( when selling price and loss is given ) Cost price = 100 Selling Price + 100 + Profit (where the Selling Price and Profit Percentage are supplied)

Hence

x = 527 - 310

Step-by-step explanation:

The required function is: 576,001 - ( 0.11 * 576,001 * x )

The value of the helicopter after 12 years, to nearest dollar is -$184320

Given data

price of a helicopter $576,001

rate of value decrease is 11%

The decrease in value will result to

= 576,001 - 0.11 * 576,001 * x

let x represent the number of years

the required function is: 576,001 - 0.11 * 576,001 * x

plugging in 12 and solving results to

= 576,001 - 0.11 * 576,001 * x

= 576,001 - 0.11 * 576,001 * 12

= 576,001 - 760321.32

Answer:

4 games

Step-by-step explanation:

Let the number of games rented from both be represented by: g

For Games - R - Us

Games-R-Us offers a video game rental program with a monthly fee of $10 plus $2 per game rental.

$10 + $2 × g

= 10 + 2g

For Games2Go

Games2Go charges a $2 monthly fee plus $4 per game.

$2 + $4 × g

= 2 + 4g

Hence,

Games-R-Us = Games2Go

10 + 2g = 2 + 4g

Collect like terms

10 - 2 = 4g - 2g

8 = 2g

g = 8/2

g = 4 games

Therefore, number of games you would have to rent from each company to have your total cost be the same amount is 4 games
