Answer:

B

Step-by-step explanation

Answer:

Option B. a = −5, b = −9, c = 12

Step-by-step explanation:

The general form of the quadratic equation is as following

ax² + bx + c = 0

Where a, b and c are constants.

And the given equation is −5x2 − 9x + 12 = 0

Comparing the given equation to the general form

  ax² + bx + c = 0

−5x2 − 9x + 12 = 0

So, a = -5  , b = -9  and   c = 12

Identifying the values a, b, and c is the first step in using the Quadratic Formula to find solution(s) to a quadratic equation.

So, the answer is option B: a = −5, b = −9, c = 12

Answer:

Nancy needs to order 5 boxes of travoprost and 9 boxes of latanoprost for her pharmacy.

Step-by-step explanation:

Nancy counts 10 boxes of travoprost and the pharmacy needs 15 boxes to maintain a minimal level in the stock.

So, there is a need to order (15 - 10) = 5 boxes of travoprost.

Again, Nancy counts 3 boxes of latanoprost and the pharmacy needs to 12 boxes.  

So, there is a need to order (12 - 3) = 9 boxes of latanoprost.

Therefore, Nancy needs to order 5 boxes of travoprost and 9 boxes of latanoprost for her pharmacy. (Answer)

Final answer:

Nancy needs to order 5 boxes of travoprost and 9 boxes of latanoprost to fulfill the pharmacy's minimal stock requirement.

Explanation:

Nancy needs to order more boxes of eye medication to meet the pharmacy's minimal stock levels. For travoprost, the pharmacy requires 15 boxes but currently has only 10 boxes. So, Nancy needs to order:

15 boxes (required amount) - 10 boxes (current amount) = 5 boxes of travoprost.

For latanoprost, the pharmacy needs 12 boxes, but only has 3 boxes in stock, meaning Nancy needs to order:

12 boxes (required amount) - 3 boxes (current amount) = 9 boxes of latanoprost.

Answer:

US$ 1,084.80 were raised from the raffle tickets and US$ 1,035 are the profits after paying the prizes.

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Number of raffle tickets sold = 1,356

Cost of each raffle ticket = US$ 4/5

Number of prizes = 6

Cost of each prize = US$ 8 3/10

2. How much money was raised from the raffle tickets?

For easier calculation, let's convert the fraction numbers to decimal numbers:

Cost of each raffle ticket = US$ 4/5 = US$ 0.80

Cost of each prize = US$ 8 3/10 = US$ 8 + 0.30 = US$ 8.30

Now, we use this formula to calculate how much money was raised and the profits:

Profits = (Number of tickets sold * Cost of each ticket) - (Number of prizes * Cost of each prize)

Replacing with the real values, we have:

Profits = 1,356 * 0.80 - 6 * 8.30

Profits = 1,084.80 - 49.80

Profits = 1,035

US$ 1,084.80 were raised from the raffle tickets and US$ 1,035 are the profits after paying the prizes.

Final answer:

The total amount of money raised from the sale of 1,356 raffle tickets, priced at 4/5 dollars each, is $1,084.8.

Explanation:

To determine how much money was raised from the raffle tickets, we first need to calculate the total cost of each ticket and then multiply it by the total number of tickets sold. The question states that each raffle ticket is sold for 4/5 dollars. Since a total of 1,356 raffle tickets were sold, the total amount raised can be calculated as follows:

Total amount raised = Price per ticket × Total number of tickets

= (4/5) × 1,356

= 1,084.8 dollars

Therefore, the total amount of money raised from the raffle tickets is $1,084.8.

Answer:

64 crates

Step-by-step explanation:

Smaller Cube Side Length = 2 1/2 feet, or, 2.5 feet

Larger Container (Cube) Side Length = 10 feet

We find volume of larger container and find volume of small crates. We divide the large volume by volume of each crate. This will give us number of crates we can fit.

Volume of Cube = x^3

Where x is the side length of the cube

Now,

Small Crate Volume = (2.5)^3 = 15.625 cubic feet

Large Container Volume = 10^3 = 1000 cubic feet

Number of crates that would fit = 1000/15.625 = 64

So, 64 crates will fit in the largest shipping container

64 crates will fit into the largest shipping container.

1. Calculate the volume of each crate:

  Volume [tex]\( V_{\text{crate}} \)[/tex] of a cube with side length s:

 [tex]\[ V_{\text{crate}} = s^3 = (2.5)^3 \] \[ V_{\text{crate}} = 2.5 \times 2.5 \times 2.5 \] \[ V_{\text{crate}} = 15.625 \text{ cubic feet} \][/tex]

2. Calculate the volume of the larger container:

  Volume [tex]\( V_{\text{container}} \)[/tex] of the larger cube-shaped container:

 [tex]\[ V_{\text{container}} = (10)^3 = 1000 \text{ cubic feet} \][/tex]

3. Determine the maximum number of crates that can fit:

  To find out how many crates can fit into the container, divide the volume of the container by the volume of one crate:

 [tex]\[ \text{Number of crates} = \frac{V_{\text{container}}}{V_{\text{crate}}} \] \[ \text{Number of crates} = \frac{1000}{15.625} \] \[ \text{Number of crates} \approx 64 \][/tex]

Initially I had 48 tokens initially

Given that , For every 8 tokens you have your friend has 3

Then, let us assume that, we have 8n tokens. Then our friend will have 3n tokens

After you give half of your tokens to your friend Your friend now has 18 more tokens than you.  

We have to find how many tokens did you start with

Now, after giving away half of tokens we will have 8n/2 = 4n tokens

And our friend will have 4n + 3n = 7n tokens.

And according to given information

Friends tokens – my tokens = 18 tokens

7n – 4n = 18  

3n = 18  

n = 6

Then, I will have initially 8n = 8 x 6 = 48 tokens.

Hence, I had 48 tokens initially

Answer:

The quantity of Type A coffee were used is 32 pounds .

Step-by-step explanation:

Given as :

The cost of type A coffee = $ 5.50 per pound

The cost of type b coffee = $ 4.25 per pound

The total cost of coffee = $ 448.00

The quantity of coffee of type B is twice than type A

Let The quantity of type A coffee = x pound

So, The quantity of type B coffee = 2 × x   pound

Now, According to question

x × $ 5.50 + 2 x × $ 4.25 = $ 448

Or,  x × $ 5.50 + x × $ 8.5 = $ 448

Or, 14 x = 448

∴ x = [tex]\frac{448}{14}[/tex]

I.e x = 32

∴ The quantity of type A coffee = 32 pound

And, The quantity of type B coffee = 2 × 32 = 64   pound

Hence The quantity of Type A coffee were used is 32 pounds . Answer

Final answer:

By setting up an equation based on the costs per pound and the relationship between quantities of coffee types A and B, we find that Kaitlin used 32 pounds of type A coffee for her blend.

Explanation:

We need to determine how many pounds of type A coffee were used in the blend, given that twice as many pounds of type B were used and that the total cost was $448.00. Let x be the pounds of type A coffee. Then, 2x will represent the pounds of type B coffee since twice as much type B is used compared to type A.

The cost equation can be represented as:

5.50x + 4.25(2x) = 448

Solving for x:

5.50x + 8.50x = 448

14x = 448

x = 448 / 14

x = 32

Therefore, Kaitlin used 32 pounds of type A coffee for her blend.

Hence,

[tex](f o g)(x) = 245x^2+6\\(g o f)(x) = 5x^2+42\\ f(g(-4)) = 3926\\g(f(5)) = 917[/tex]
