Answer:
B is the correct option.
Step-by-step explanation:
Place the values from the given options in equations of f(n) and g(n).
Write the answer of each of the following.
For instance, option A gives:
f(6)= 31
g(6) = 24
Option B gives:
f(7)= 63
g(10)= 36
Option C gives:
f(5)= 15
g(8)=30
Option D gives:
f(5)=15
g(5)=21
Thus option B is correct because f(7) is greater than g(10).
Answer:
B. f(7) > g(10)
Step-by-step explanation:
f(7) = 2⁶ - 1 = 63
g(10) = 3×10 + 6 =36
since 63>36 then f(7) > g(10)

If a chessboard were to have pennies placed on each square such that 1 penny was placed on the first square, 2 on the second, 4 on the third, and so on (doubling the number of pennies on each subsequent square), how many pennies would be on the chessboard when finished?
How many squares are on the chessboard?
Answers
This is just like the rice chessboard problem! To quickly get the answer, we can simply do (2^64)-1.
Take a look at the following:
1+2+4+8=15=2^4-1
1+2+4+8+16=31=2^5-1
There's that rule involved, and we can simply use 2^64-1 instead of adding too many numbers.

The formula for calculating the area of a square is given by :
Area = [tex]l^{2}[/tex]
where [tex]l[/tex] is the length of a side .
Therefore , the area of one of the square given implies :
Area = [tex]7^{2}[/tex]
Area [tex]= 49[/tex]
And since there are 5 squares in all , the area will therefore be :
Area = [tex]5[/tex] x[tex]49[/tex]

Solve the equation for 3y-4=6-2y
Answers
To solve the equation, you need to isolate/get "y" by itself in the equation:
3y - 4 = 6 - 2y Add 2y on both sides
3y + 2y - 4 = 6 - 2y + 2y
5y - 4 = 6 Add 4 on both sides
5y - 4 + 4 = 6 + 4
5y = 10 Divide 5 on both sides
[tex]\frac{5y}{5} =\frac{10}{5}[/tex]
y = 2
PROOF
3y - 4 = 6 - 2y Substitute/plug in 2 for y
3(2) - 4 = 6 - 2(2)
6 - 4 = 6 - 4
2 = 2
After Solving the equation for 3y-4=6-2y, we get y = 2. We must isolate the variable y on one side of the equation in order to get the solution to the equation 3y - 4 = 6 - 2y. Here's a step-by-step procedure:
Start by solving 3y - 4 = 6 - 2y, which is the provided problem.
Add 2y to both sides of similar phrases to combine them: 3y + 2y - 4 = 6 - 2y + 2y.
Simply put, this is: 5y - 4 = 6.
Add 4 to both sides of the variable word to isolate it: 5y - 4 + 4 = 6 + 4.
This may be summarised as 5y = 10.
To find y, multiply both sides of the equation by 5. (5y) / 5 = 10 / 5.
This may be condensed to: y = 2.
Consequently, y = 2 is the answer to the equation 3y - 4 = 6 - 2y.

Step-by-step explanation:
y = 1.12x + 28.78 represents the height of the puppy. Here that height is 54 cm:
Then 54 = y = 1.12x + 28.78
Combining the constants, we get 1.12x = 25.22. Dividing both sides by 1.12, x turns out to be 22.5 weeks.

Darius uses the shadow method to estimate the height of the flagpole. He finds that a 5-foot stick casts a 4-foot shadow. At the same time , he finds that the flagpole casts a 20-foot shadow . What is the height of the flagpole. Sketch a diagram.
Answers
Answer:
The height of the flagpole is 25 foot.
Step-by-step explanation:
Given:
Height of the stick = 5 foot
Shadow of the stick = 4 foot
Another one:
Height of the flagpole = 'x'
Shadow of the flagpole = 20 foot
Note:The shadows are formed at the same time of the day so the Sun makes an equal angle with both the situation.
Here from both ends it forms two similar triangles.
So,
We can say that:
⇒ [tex]\frac{Height\ of\ the\ flagpole}{Shadow\ of\ the\ flagpole}=\frac{Height\ of\ the\ stick}{Shadow\ of\ the\ stick}[/tex]
⇒ [tex]\frac{x}{20}=\frac{5}{4}[/tex]

(d) [tex]\sum_{n=2}^{5} n ![/tex]
Answer:
Option a: [tex]\sum_{n=2}^{5}(n-1) ![/tex] is the correct answer.
Explanation:
Option a: [tex]\sum_{n=2}^{5}(n-1) ![/tex]
By substituting the values of n and expanding the summation, we have,
[tex](2-1) !+(3-1) !+(4-1) !+(5-1) ![/tex]
Subtracting, we have,
[tex]1 !+2!+3 !+4 ![/tex]
Expanding the factorial,
[tex]1+(2*1)+(3*2*1)+(4*3*2*1)[/tex]
Simplifying, we get,
[tex]1+2+6+24[/tex]
Thus, the summation [tex]\sum_{n=2}^{5}(n-1) ![/tex] represents the series [tex]1+2+6+24[/tex]
Hence, Option a is the correct answer.

Expanding the factorial,
[tex]0+1+(2*1)+(3*2*1)[/tex]
Simplifying, we get,
[tex]0+1+2+6[/tex]
Thus, the summation [tex]\sum_{n=0}^{3} n ![/tex] does not represents the series [tex]1+2+6+24[/tex]
Hence, Option b is not the correct answer.
Option c: [tex]\sum_{n=1}^{4}(n+1) ![/tex]
By substituting the values of n and expanding the summation, we have,
[tex](1+1) !+(2+1) !+(3+1) !+(4+1) ![/tex]

Simplifying, we get,
[tex]2+6+24+120[/tex]
Thus, the summation [tex]\sum_{n=1}^{4}(n+1) ![/tex] does not represents the series [tex]1+2+6+24[/tex]
Hence, Option c is not the correct answer.
Option d: [tex]\sum_{n=2}^{5} n ![/tex]
By substituting the values of n and expanding the summation, we have,
[tex]2!+3!+4!+5![/tex]

If the total surface area of a cube is 302.46ft2 what best describes the length of the side of the cube?
Answers
Answer:
7.1ft
Step-by-step explanation:
The formula for calculating the total surface area of a cube is 2(L²+L²+L²)
=2(3L²)
= 6L²
Where L is the length of the cube
If the total surface area of a cube is 302.46ft², then
302.46 = 6L²
L² = 302.46/6
L² = 50.41
L =√50.41
L = 7.1ft
The length of the side of the cube is 7.1ft
The length of the side of the cube is approximately [tex]\( 7.1 \, \text{ft} \).[/tex]
To find the length of the side of a cube given its total surface area, we need to use the formula for the surface area of a cube.
The formula for the surface area of a cube is:
[tex]\[ \text{Surface Area} = 6s^2 \][/tex]
where s is the length of a side of the cube.
Given the total surface area is [tex]\( 302.46 \, \text{ft}^2 \)[/tex], we can set up the equation:
[tex]\[ 6s^2 = 302.46 \][/tex]
To solve for s we first divide both sides by 6:
[tex]\[ s^2 = \frac{302.46}{6} \][/tex]
[tex]\[ s^2 = 50.41 \][/tex]
Next, we take the square root of both sides to find s
[tex]\[ s = \sqrt{50.41} \][/tex]
[tex]\[ s \approx 7.1 \, \text{ft} \][/tex]
Thus, the length of the side of the cube is approximately [tex]\( 7.1 \, \text{ft} \).[/tex]

C)$11.5
D)$12
E)$11.25
Answers
Answer:
The answer is A)$10.50
Step-by-step explanation:
In order to solve the average amount, you have to add the total amount of money spent and divide it by the total number of times you spent money on food. The total sum of money spent was $63. If you divide that by how many times you ate (6 times) you'll get the dividend/answer of 10.5.
Hope this helps :)
You are spending, on average, A) $10.50 per day on food.
The correct answer is A) $10.50.
To find the average amount spent per day on food, you need to add up the total amount spent over the 6 days and then divide it by the number of days (6).
Total amount spent on food = $8 + $14 + $12 + $11 + $5 + $13
= $63
Average amount spent per day = Total amount spent / Number of days
= $63 / 6
= $10.50
