When a 49 pound weight is attached to a spring, the spring stretches 7 inches. Assume that the length of the spring y varies directly
with the weight attached x. Write and solve a direct variation equation to
find the length of the spring when a 63 pound weight is attached.
F(x)= 5x^2+6, g(x)= 7x find (f o g)(x), find (g o f)(x), find f(g(-4)), fine g(f(5))
[tex](f o g)(x) = 245x^2+6\\(g o f)(x) = 5x^2+42\\ f(g(-4)) = 3926\\g(f(5)) = 917[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 5x^2+6\\g(x) = 7x[/tex]
So
[tex](f o g)(x) = 5(7x)^2+6\\= 5(49x^2)+6\\=245x^2+6\\(g o f)(x) = 7(5x^2+6)\\= 35x^2+42\\(fog(x))=245x^2+6f(g(-4)) = 245(-4)^2+6 \\=245(16)+6\\=3920+6\\=3926\\g(f(x)) = 35x^2+42\\g(f(5)) = 35(5)^2+42\\=35(25)+42\\=875+42\\=917[/tex]
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]

10. A square picture has a 1-inch frame around it. If the
area of the frame alone is 80 in.2, what is the area of the
picture?
Answer:
361 sq, inches.
Step-by-step explanation:
Let us assume that the dimensions of the square picture are P in × P in.
So, the area of the picture alone is, A = P²
Now, if the photo has a frame of 1 inch wide, then the dimensions of the photo with frame are (P + 2) in × (P + 2) in.
So, the area of the photo with frame is A' = (P + 2)(P + 2) = (P + 2)²
Now, the area of the frame alone is 80 sq. inches.
Hence, A' - A = 80
⇒ (P + 2)² - P² = 80
⇒ 4P + 4 = 80
⇒ 4P = 76
⇒ P = 19 inches.
So, the area of the picture is = 19² = 361 sq. inches. (Answer)
361 sq, inches.

Nancy is taking inventory in the pharmacy to make sure there is enough eye medication in the pharmacy. She counts 10 boxes of travoprost and the pharmacy needs 15 boxes to maintain a minimal level in stock. Nancy counts 3 boxes of latanoprost and the pharmacy needs to 12 boxes. Calculate how many boxes of each Nancy needs to order.
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.
Katelynn earned $1240 in two weeks at the recreation
center during a trap shooting tournament. She earned
$480 the first week and the rest the second week.
Write an algebraic equation to model the situation.
x = 1240-y can be used to model the situation where x is the amount earned in second week.
Step-by-step explanation:
Given,
Total amount earned = D = $1240
Amount earned in first week = y = $480
Let,
x be the amount earned in second week.
Therefore,
Total amount earned = Amount earned in 1st week + 2nd week amount
D = x + y
1240 = x + y
Solving for x;
[tex]x= 1240- y [/tex]
x = 1240-y can be used to model the situation where x is the amount earned in second week.

A shipping company is loading cube shaped crates into a larger cube shaped container the smaller cubes have side lengths 21/2 feet,and the larger shipping container has side lengths of 10 feet. How many crates will fit in the largest shipping container?Explain your reasoning
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]
Identifying the values a, b, and c is the first step in using the Quadratic Formula to find solution(s) to a quadratic equation. What are the values a, b, and c in the following quadratic equation? −5x2 − 9x + 12 = 0
A:a = −9, b = 12, c = 0
B: a = −5, b = −9, c = 12
C: a = 5, b = 9, c = 12
D:a = 9, b = 12, c = 0
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
In one year , Melinda’s parents spend 2,440.90 on cable and internet service . If they spend the same amount each month , estimate with the monthly fee is for cable and internet .
Answer:
The monthly fee for cable and internet is 200.
Step-by-step explanation:
Given:
Amount spend on one year for cable and internet service is 2440.90.
Now, to get the monthly fee for same amount spend on a year, by dividing the amount spend on a year with 12. As in one year there are 12 months.
So, [tex]2440.90\div 12[/tex]
=[tex]203.41[/tex]
By estimating the amount we get 200. As estimating means to round off the number to the nearest of whole number.
Therefore, the monthly fee for cable and internet is 200.

For every 8 tokens you have your friend has 3.
After you give half of your tokens to your friend Your friend now has 18 more tokens than you.
How many tokens did you start with.
Initially I had 48 tokens initially
Solution: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.
