simplify the quotient 3^1 divided by 3^4

Answers

Answer:

1/243 for edge

Step-by-step explanation:

The simplified form of the quotient 3⁻¹ divided by 3⁴ is 1/243.

What is the quotient?

A quotient is defined as when dividing one number by another, the result is called the quotient.

To simplify the quotient 3⁻¹ divided by 3⁴, we can use the rule that says when we divide two exponential expressions with the same base, we can subtract their exponents.

So, we have:

3⁻¹ ÷ 3⁴

3⁻¹ divided by 3⁴ = 3⁻¹⁻⁴

Now, we can simplify the expression by subtracting the exponents:

3⁻¹⁻⁴ = 3⁻⁵ = 1/3⁵ = 1/243

So, the simplified form of the quotient 3⁻¹ divided by 3⁴ is 1/243.

Step-by-step explanation:

ted popped a baseball straight up with an initial velocity of 48 ft/s. The height, h, in feet, of the ball above the ground is modeled by the function h(t)=-16t2 +48t+3. How long was the ball in the air if the catcher the ball 3 feet above the ground?

Answers

Answer:

3 seconds

Step-by-step explanation:

We have to give us the following function h (t) = - 16 * t ^ 2 + 48 * t + 3

Now, they tell us that the height is 3 feet, therefore replacing that value we have left:

3 = -16 * t ^ 2 + 48 * t + 3, operating cancels 3. And it would be:

-16 * t ^ 2 + 48 * t = 0

Removing common factor -16 * t, it would be:

(-16 * t) * (t - 3) = 0

We have two solutions:

-16 * t = 0 ---> t = 0

 t - 3 = 0 ---> t = 3

Because the time cannot be 0 seconds, the time it would take the ball in the air is 3 seconds.

Final answer:

The ball was in the air for 3 seconds.

Explanation:

To find how long the ball was in the air when the catcher caught it 3 feet above the ground, we need to solve for t in the equation -16t^2 + 48t + 3 = 3. Simplifying the equation, we get -16t^2 + 48t = 0. Factoring out 16t, we have 16t(-t + 3) = 0. Setting each factor equal to zero, we find two solutions: t = 0 and t = 3 seconds. Since we are only interested in the time the ball was in the air, we discard the solution t = 0 and conclude that the ball was in the air for 3 seconds.

Kendra gets a paycheck of $300 after 5 days of work. At this rate, how much does
she get paid for working 24 days?​

Answers

Answer:1440

Step-by-step explanation:

I’m guessing that’s cuz 300/15 is 60 then 60 times 24?

First, let's start by figuring out how much Kendra gets paid per day. To do this, we can divide 300 by 5. 300 / 5 equals $60 per day.

Next, we can take the amount she gets paid per day and multiply it by the number of days, 24. 24 * 60 = $1440.

At the rate of $60 per day, Kendra will get paid $1440 for working 24 days.

Graph the quadratic inequality.
y>x2 - 6x + 11

Answers

Answer:

put the ^ when you do exponents!

Step-by-step explanation:

There are three parts to graphing an inequality.

1. determine if the line will be dashed or solid

2. determine where you will shade in

3 graph with the appropriate line and shade

1. it is just > and not ≥ so the line will be dashed, which means the line itself is not part of the answer.

2. it is y> so you shade in the area inside the parabola.  if y was an actal number it might be more complicated

3. graph x^2 - 6x + 11.  If that seems a bit hard, put it into vertex form by completing the square.

y = x^2 - 6x + 11

y = (x - 3)^2 +2

Since x^2 is positive it opens upward and then plug in 0 for x and y in y = (x - 3)^2 +2 to get the x and y intercepts and the -3 and +2 tells you the vertex (in this case the minimum) is at (3,2),  then remember the points are mirrored on either side of the vertex.  so if the y intercept is 2 to the left and one higher than the vertex, there will also be a point 2 to the RIGHT and 1 up.  then just connect the dots.  Keep in mind there may not be any x intercepts if it never goes below the x axis *hinthintwinkwink*

if all else fails just graph a handful of points to get the idea of the shape.  Just remember you are shading inside of the parabola and using dashed lines.

O D. (x + 2) + (y - 3) - 9​

Answers

Answer:

(x - 2)² + (y + 3)² = 9

Step-by-step explanation:

(x - h)² + (y - k)² = r²

(x - 2)² + (y - (-3))² = 3²

(x - 2)² + (y + 3)² = 9

The equation of the circle is (x - 2)^2 + (y + 3)^2 - 9 = 0.

The correct option is (B).

What is a circle?

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point.

As per the given data:

We are given the coordinates for the center of a circle and the measure of the radius of the circle. We have to find out the equation of the circle

The coordinates of the center of the circle (O) = (2, -3)

The radius of the circle = 3

The standard equation of the circle with center (h, k) and radius r is given by:

(x - h)^2 + (y - k)^2 = r^2

By substituting (h, k) ⇒ (2, -3) and r = 3

(x - 2)^2 + (y + 3)^2 = 3^2

= (x - 2)^2 + (y + 3)^2 = 9

The equation of the circle is (x - 2)^2 + (y + 3)^2 - 9 = 0.

Hence, The equation of the circle is (x - 2)^2 + (y + 3)^2 - 9 = 0.

#SPJ7

A stocks value decreased the same amount each day for 4 days. If the total change in value was -2.5 what was the change each day?

Answers

Answer:

-0.625

Step-by-step explanation:

Final answer:

The stock's value decreased by -0.625 each day over a period of four days, calculated by dividing the total decrease of -2.5 by the number of days.

Explanation:

The student's question pertains to finding the amount by which a stock's value decreased each day over four days, given that the total decrease was -2.5. To solve this problem, we use the concept of an arithmetic series, where each term changes by a constant difference. Since we know the total change in the stock's value was -2.5 over four days, we divide the total change by the number of days to find the daily change.

To calculate the change in stock value each day, we can use the formula:

Daily Change = Total Change / Number of Days

Plugging the values into the formula, we get:

Daily Change = -2.5 / 4 = -0.625

Therefore, the stock value decreased by -0.625 each day for the 4-day period.

Six times a number plus three times a second number is 27. The second
number is one more than two times the first number. What is the second
number?

Answers

Answer:5 1/3

Step-by-step explanation:

number = n

second number = s

6n + 3s = 27

2n + 1 = s

6n + 3(2n + 1) = 27

6n + 6n + 1 = 27

12n = 26

n = 26/12

n = 2 1/6

2(2 1/6) + 1 = s

4 1/3 + 1 = s

5 1/3 = s

Final answer:

To find the second number, we create a system of linear equations using the given information and solve for the variables. The solution shows that the second number is 5.

Explanation:

The student's question involves setting up a system of two linear equations and solving them to find the values of two unknown numbers.

Let the first number be x and the second number be y. We are given the following equations based on the problem:

6x + 3y = 27

y = 2x + 1

First, we can substitute the second equation into the first to solve for x:

6x + 3(2x + 1) = 27

6x + 6x + 3 = 27

12x + 3 = 27

12x = 24

x = 2

Now, substitute x = 2 into the second equation to find y:

y = 2(2) + 1

y = 4 + 1

y = 5

Therefore, the second number, y, is 5.

D . 2x^2 – 3x+ 10 = 2x^2 + 21x = -11/3     <- No

Step-by-step explanation:

Solve for x over the real numbers:

5 x + 2 x - 4 = 2 x^2

5 x + 2 x - 4 = 7 x - 4:

7 x - 4 = 2 x^2

Subtract 2 x^2 from both sides:

-2 x^2 + 7 x - 4 = 0

Divide both sides by -2:

x^2 - (7 x)/2 + 2 = 0

Subtract 2 from both sides:

x^2 - (7 x)/2 = -2

Add 49/16 to both sides:

x^2 - (7 x)/2 + 49/16 = 17/16

Write the left hand side as a square:

(x - 7/4)^2 = 17/16

Take the square root of both sides:

x - 7/4 = sqrt(17)/4 or x - 7/4 = -sqrt(17)/4

Add 7/4 to both sides:

x = 7/4 + sqrt(17)/4 or x - 7/4 = -sqrt(17)/4

A rectangular piece of paper is 6 inches wide and 8 inches long. A square with a side of 3/4 inch is cut out from each of the four corners. How much paper is left after the corners are removed?

Answers

Answer:

45 in.

Step-by-step explanation:

6 x 8 = 48

.75 x 4 = 3

48 - 3 = 45

45 inches left

After cutting out four square corners, each with a side length of 3/4 inch from a 6 by 8 inches rectangular piece of paper, 45.75 square inches of paper is left.

To solve how much paper is left after the corners are removed, we need to calculate the total area of the paper and subtract the total area of the corners that were cut out.

The original dimensions of the paper are 6 inches by 8 inches, so its total area is:

Area of rectangle = width times length = 6 inches times 8 inches = 48 square inches.

Each corner is a square with a side of 3/4 inch, so the area of one corner is:

Area of one square corner = (3/4 inch) times (3/4 inch) = 9/16 square inches.

Since there are four corners:

Total area removed = 4 inches (9/16 square inches) = 9/4 square inches = 2.25 square inches.

Finally, subtract the area removed from the total area to find the remaining area:

Remaining area = Total area of rectangle - Total area removed

Remaining area = 48 square inches - 2.25 square inches = 45.75 square inches.

A standard deck of 52 cards contains 4 suits: hearts, clubs, diamonds, and spades. Each suit consists of cards
numbered 2 through 10, a jack, a queen, a king, and an ace.
Zhi Qing decides to pick one card at random from a standard deck of 52 cards. Let A be the event that she
chooses a three card and B be the event that she chooses a seven card.
What is P(A or B), the probability that the card Zhi Qing chooses is either a three or a seven?

Answers

Answer:

[tex]\frac{2}{13}[/tex]

Step-by-step explanation:

In probability,

"OR" means "addition"

"AND" means "multiplication"

We want probability of A "OR" B, that means we find each individual probability and "ADD" them.

P(A) means P(choosing a 3 card):

There are 4 three-cards, 1 from each suit, and a total of 52 cards, so

P(A) = 4/52 = 1/13

P(B) means P(choosing a 7 card):

There are 4 seven-cards, 1 from each suit, and a total of 52 cards, so

P(B) = 4/52 = 1/13

Now,

P(A or B) = P(A) + P(B) = 1/13 + 1/13 = 2/13

The answer is  [tex]\frac{2}{13}[/tex]

Answer:

nerd kjhvgcfxdgchvbjknlmStep-by-step explanation:1=22=1therefore 2=1-1 -11=0?See it doesn't work, therefore its wrong

Final answer:

The probability of drawing a blue marble from a box containing 8 red, 9 blue, and 11 yellow marbles is calculated by dividing the number of blue marbles (9) by the total number of marbles (28), resulting in a probability of 9/28.

Explanation:

The question asks for the probability that a marble chosen randomly from a box is blue, given that the box contains 8 red marbles, 9 blue marbles, and 11 yellow marbles. To find this probability, you divide the number of blue marbles by the total number of marbles. Here's the calculation:

Total number of marbles = 8 red + 9 blue + 11 yellow = 28 marbles.Number of blue marbles = 9.Probability of drawing a blue marble = Number of blue marbles / Total number of marbles = 9 / 28.

Therefore, the probability of drawing a blue marble from the box is 9/28.
