Answer:
Shannon's expression:
[tex]\frac{4.2 \times 10^{9} }{1.4 \times 10^{4} }[/tex]
Kristoph's expression:
[tex]\frac{4.2 \times 10^{2} }{1.4 \times 10^{-3} }[/tex]
(A)Notice that both expression has the same coefficient numbers: 4.2 and 1.4. That means to have the same results, we just need to have the same powers.
Without dividing the complete expression, you can observe that both powers are the same, because each you subtract 9-4 = 5, and 2-(-3) = 5, both gives the same exponent to the power of 10.
Therefore, both expression give the same result, because they have the same numbers and the same powers.
(B)Let's solve the division to have the result in scientific notation.
Shannon's expression:
[tex]\frac{4.2 \times 10^{9} }{1.4 \times 10^{4} }=3 \times 10^{9-4}=3 \times 10^{5}[/tex]
Kristoph's expression:
[tex]\frac{4.2 \times 10^{2} }{1.4 \times 10^{-3} }=3 \times 10^{2-(-3)}=3 \times 10^{5}[/tex]
(C)The standard form refers to each number written without the power. To do so, we need to move the decimal points the number of spots as the exponent demands. Notice that the exponent is 5, that means, we need to move the decimal point 5 spots to the right.
[tex]3 \times 10^{5}=300000[/tex]
Therefore, the standard value of the expressions is 300,000.

Thank you so much.
Answer:

Step-by-step explanation:
If ∑aₙ converges, then lim(n→∞)aₙ = 0.
Using ratio test, we can determine if the series converges:
If lim(n→∞) |aₙ₊₁ / aₙ| < 1, then ∑aₙ converges.
If lim(n→∞) |aₙ₊₁ / aₙ| > 1, then ∑aₙ diverges.
lim(n→∞) |(100ⁿ⁺¹ / (n+1)!) / (100ⁿ / n!)|
lim(n→∞) |(100ⁿ⁺¹ / (n+1)!) × (n! / 100ⁿ)|
lim(n→∞) |(100 / (n+1)|
0 < 1
The series converges. Therefore, lim(n→∞)aₙ = 0.

The Smiths spend 10% of their budget on entertainment. Their total budget this year is $2,000 more than last year, and this year they plan to spend $2,450 on entertainment. What was their total budget last year?
Answer:
$22500
Step-by-step explanation:
First, we have to find the total budget for this year.
They spend 10% on entertainment and $2450 will be spent on entertainment this year.
Let the total budget this year be x. Therefore:
[tex]\frac{10}{100} * x = 2450[/tex]
Simplifying:
[tex]10x = 2450 * 100 \\\\10x = 245000\\\\x = 245000 / 10[/tex]
=> x = $24500
Their total budget of this year is $24500.
Since they will spend $2000 more this year than last year, we have to deduct $2000 from this year's budget to find last year's.
This means that their budget last year was:
$24500 - $2000 = $22500
Their budget last year was $22500.

a bullet fired from a gun traveled 3,600 m south in 6.0 seconds. What was its velocity in (a) m/sec and (b) km/hour?
Step-by-step explanation:
Velocity = Displacement/Time
a) Velocity in m/s = 3600m/6s
= 600m/s
b) (Converting m into km)
1000m = 1km
3600m = ?
3600/1000 = 3.6km
(Converting secs to hours)
1mins = 60secs
60mins = ?
60 * 60 = 3600 secs
This means there are 3600 secs in 1 hour
3600secs = 1hour
6.0 secs = ?
6.0/3600 = 0.00167 hours (approximately)
Velocity in km/h = 3.6km/0.00167h
= 2155.69km/h (approximately)
In summary...
a) 600m/s
b) 2155.69km/h
The bullet's velocity is 600 meters per second (m/s) and also 2,160 kilometers per hour (km/h), calculated by dividing the distance traveled by the time taken and converting the units accordingly.
To find out the bullet's velocity in meters per second (m/s), you'll need to use the formula for velocity which is distance traveled divided by the time taken. Here, the bullet traveled 3,600 meters in 6.0 seconds.
Velocity in m/s = Distance / Time
Velocity in m/s = [tex]\frac{3600}{6}[/tex]
Velocity in m/s = 600 m/s
For velocity in kilometers per hour (km/h), first convert meters to kilometers by dividing by 1,000 and then convert seconds to hours by dividing by 3,600 (the number of seconds in an hour).
Velocity in km/h =[tex]\frac{ (Velocity in m/s x 3,600) }{1000}[/tex]
Velocity in km/h = [tex]\frac{(600 m/s x 3,600) }{1000}[/tex]
Velocity in km/h = 2,160,000 / 1,000
Velocity in km/h = 2,160 km/h
Therefore, the bullet's velocity is 600 m/s and 2,160 km/h.
Objects in free fall are constantly picking up speed as they fall back to Earth (prior to reaching terminal velocity).

If y = 3x squared + 4 find the value of y when x = 2
Answer:
The value of y is 16.
Step-by-step explanation:
You have to substitute x = 2 into the equation :
[tex]y = {3x}^{2} + 4[/tex]
Let x = 2,
[tex]y = 3( {2)}^{2} + 4[/tex]
[tex]y = 3(4) + 4[/tex]
[tex]y = 12 + 4[/tex]
[tex]y = 16[/tex]
Answer:
y = 16
Step-by-step explanation:
Let's solve your equation together
3x^2 + 4
We have been given that x = 2
So first we must replace x by 2.
y = 3(2)^2 + 4
Now we solve the equation
2^2 = 4
y = 3(4) + 4
3 * 4 = 12
y = 12 + 4
12 + 4 = 16
y = 16

What are the solutions to the quadratic equation 3(x - 4)2 = 75?
O x= -9 and x = 1
x= -5 and x = 5
O x = -4 and x = 4
Ox= -1 and x = 9
OOO
Answer:
x = -1 and x = 9
Step-by-step explanation:
3(x-4)^2 = 75
(x-4)^2 = 75/3 = 25
(x-4)=[tex]\sqrt25[/tex]
(x-4)= 5 or (x-4)=-5
x=9 or x= -1
Final answer:
To solve the quadratic equation 3(x - 4)^2 = 75, we isolate the squared term, take the square root of both sides, and solve for x, which gives us the solutions x = -1 and x = 9.
Explanation:
The equation given is 3(x - 4)2 = 75. To solve for x, follow these steps:
Divide both sides of the equation by 3 to isolate the squared term: (x - 4)2 = 25.Take the square root of both sides of the equation to remove the exponent: x - 4 = ±5.Add 4 to both sides of the equation to solve for x: x = 4 ± 5.So, the solutions to the equation are x = -1 and x = 9.

Kevin is making a picture frame. He has a piece of trim that is 3 feet long.
How many 14−inch-long pieces can Kevin cut from the trim?
How much of a foot will he have left over?
Kevin can cut 14−inch-long pieces with of a foot left over.
Kevin can cut approximately 2 pieces of 14-inch-long trim from his 3-foot-long trim, with about 0.66667 feet left over.
To find out how many 14-inch-long pieces Kevin can cut from a 3-foot-long trim, we need to convert everything to the same unit. Since Kevin's trim is given in feet, we need to convert inches to feet to make the comparison easier.
[tex]1 foot = 12 inches[/tex]
So, 14 inches is equal to:
[tex]\[14 \text{ inches} \times \frac{1 \text{ foot}}{12 \text{ inches}} = \frac{14}{12} \text{ feet}\][/tex]
[tex]\[= 1.16667 \text{ feet}\][/tex]
Now, we can find out how many 14-inch-long pieces Kevin can cut from the 3-foot-long trim:
[tex]\[ \text{Number of pieces} = \frac{\text{Length of trim}}{\text{Length of each piece}} \][/tex]
[tex]\[ \text{Number of pieces} = \frac{3 \text{ feet}}{1.16667 \text{ feet}} \][/tex]
[tex]\[ \text{Number of pieces} \approx 2.571 \][/tex]
Now, let's find out how much of a foot will be left over:
[tex]\[ \text{Leftover} = \text{Length of trim} - (\text{Number of pieces} \times \text{Length of each piece}) \][/tex]
[tex]\[ \text{Leftover} = 3 \text{ feet} - (2 \times 1.16667 \text{ feet}) \][/tex]
[tex]\[ \text{Leftover} = 3 \text{ feet} - 2.33333 \text{ feet} \][/tex]
[tex]\[ \text{Leftover} \approx 0.66667 \text{ feet} \][/tex]
Complete correct question:
Kevin is making a picture frame. He has a piece of trim that is 3 feet long.
How many 14-inch-long pieces can Kevin cut from the trim?
How much of a foot will he have left over?
Kevin can cut ______ 14-inch-long pieces with ______ of a foot left over.

Bonnie had 1 one-dollar bill, 2 five-dollar bills, and 2 ten-dollar bills in her pocket. She randomly took 3 bills from her pocket. How much money could Bonnie have taken from her pocket?
Answer:
There are 5 different outcomes, $30, $21, $20, $16 and $11.
Step-by-step explanation:
Bonnie has a total of 6 bills in her pocket. If she takes 3 random bills, this means that there are 20 different possibilities but the five dollar bills and ten dollar bills are not indistinctive so the number is not 20 for this example.
She can take the 1 dollar bill and the two 5 dollar bills which would make 11 dollars.
She can take the 1 dollar bill and the two 10 dollar bills which would make 21 dollars.
She can take the 1 dollar bill, one 5 dollar bill and one 10 dollar bills which would make 16 dollars.
She can take two 5 dollar bills and one 10 dollar bill which would make 20 dollars.
She can take two 10 dollar bills and one 5 dollar bill which would make 30 dollars.
So there are 5 different outcomes, $30, $21, $20, $16 and $11.
I hope this answer helps.
Final answer:
Bonnie could have possibly drawn $11, $21, $20, or $25 by selecting any 3 bills out of 1 one-dollar bill, 2 five-dollar bills, and 2 ten-dollar bills.
Explanation:
The question concerns the amount of money Bonnie could have taken from her pocket after randomly selecting 3 bills. To answer this, let's consider her initial set of bills: 1 one-dollar bill, 2 five-dollar bills, and 2 ten-dollar bills.
Here are the possible combinations of 3 bills she could draw:
1 one-dollar bill and 2 five-dollar bills: $1 + $5 + $5 = $11
1 one-dollar bill and 2 ten-dollar bills: $1 + $10 + $10 = $21
2 five-dollar bills and 1 ten-dollar bill: $5 + $5 + $10 = $20
1 five-dollar bill and 2 ten-dollar bills: $5 + $10 + $10 = $25
Therefore, the amounts of money Bonnie could have drawn are $11, $21, $20, and $25.
