Answer: The length is 10ft, the width is 7ft.

Step-by-step explanation:

Let L be the length

Let w be the width

The equation for the perimeter is:

2L+2w=34

We also know that L=2w-4

So we can insert L=2w-4 into 2L+2w=34

2(2w-4)+2w=34

4w-8+2w=34

6w=42

w=7

If the width is 7, we can insert it into 2L+2w=34 to find out the length

2L+14=34

2L=20

L=10

The width is 7 ft, the length is 10 ft.

The length and width of the rectangle are 10 feet and 7 feet respectively. This is determined by setting up and solving equations based on the given information about the relationship between the length and width and the perimeter of the rectangle.

Given that the length (L) of the rectangle is 4 less than twice the width (W), we can represent this as:

L = 2W - 4

. We also know that the perimeter (P) of the rectangle is 34 feet. The formula for the perimeter of a rectangle is

P = 2L + 2W

. Substituting L in the perimeter equation gives

P = 2(2W - 4) + 2W = 34

. Simplifying the equation leads to

4W - 8 + 2W = 34

, and then

6W = 42

when you add 8 to both sides. Solving for W gives

W = 7 feet

. Substituting W = 7 into the length equation gives

L = 2(7) - 4 = 10 feet

. Therefore, the width and length of the rectangle are 7 feet and 10 feet respectively.

6 cupcakes is 1/4 of 24 ( 24 / 6 = 4).

This means you would need 1/4 the amount of flour.

Divide the amount needed for 24 cups by 4:

15.25 / 4 = 3.8125

Round answer as needed.

Answer:

Final answer:

By applying the given formula d = sqrt(3h/2), we find that Addison can see 2.82 miles farther to the horizon than Kaylib, based on their eye-level heights above sea level.

Explanation:

The question asks how much farther Addison can see to the horizon compared to Kaylib based on their different eye-level heights above sea level, using the formula d = sqrt(3h/2). To solve this, we need to first calculate the distance each person can see to the horizon and then find the difference between the two distances.

Let's calculate the distance for Kaylib:
h = 48 ft, so d = sqrt(3 * 48 / 2) = sqrt(72) = 8.49 miles.

Now let's calculate the distance for Addison:
h = 85¹⁄₃ ft, which we convert to a decimal: 85.333 ft, so d = sqrt(3 * 85.333 / 2) = sqrt(128) = 11.31 miles.

The difference between Addison's horizon and Kaylib's is 11.31 miles - 8.49 miles = 2.82 miles.

Addison can see 2.82 miles farther to the horizon than Kaylib.

Step-by-step explanation:

Its geometric as you are multiplying by -3 each time

Answer:

Step-by-step explanation:

If we pay attention to the sequence, we would observe that [tex]f(n)[/tex] is increasing by a reason of [tex]-3[/tex], because

[tex]12(-3)=-36\\-36(-3)=108\\108(-3)=-324\\-324(-3)=972[/tex]

So, basically, each term is being multiplied by [tex]-3[/tex], that's what makes the sequence, which is a geometric sequence, because it's being built by a factor, that is, a number which multiplies each term.

When you have to deduct if you have a arithmetic sequence or a geometric sequence, you need to observe if such sequence is increasing or decreasing faster. Like this case, you can see that the numbers are increasing rapidly, that means it's built based on a factor, not a difference, because when we use a difference to form a sequence, that will grow slower and it would be an arithmetic sequence.

Therefore, the given sequence is geometric, which reason is -3.

Subtract the cost of the pencils from the total cost. This will be he amount she spent on erasers. Then divide that amount by the cost of each eraser to get the total.

She bought 10 erasers.

Final answer:

The second car, starting 1/2 hour late and traveling at 55 miles per hour, will take 2.25 hours to catch up to the first car. This means it will catch up before the first car, traveling at 45 miles per hour, reaches the destination 135 miles away in 3 hours.

Explanation:

The question involves calculating the time it will take for the second car, traveling at an average speed of 55 miles per hour and starting 1/2 hour later, to catch up to the first car, which left on time traveling at an average speed of 45 miles per hour to a destination 135 miles away. To solve this, we need to find when both cars have traveled the same distance.

Finally, since the first car travels at 45 miles per hour, we calculate if it arrives before being caught: Time of travel for the first car to reach 135 miles is 135 miles / 45 miles per hour = 3 hours. Since 2.25 hours (the catch-up time) is less than 3 hours (the travel time to the destination), the second car will indeed catch up to the first car before it arrives at the football game.

Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.

The solution is Option D.

The solutions to the quadratic equation A = x² - 7x + 13 = 0 is given by

x = ( 7 + √3i ) / 2 and x = ( 7 - √3i ) / 2

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

x² - 7x + 13 = 0   be equation (1)

On simplifying the equation , we get

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

Substituting the values in the equation , we get

x = [ - ( -7 ) ± √ ( ( 49 ) - 4 x ( 13 ) ) ] / 2

On simplifying the equation , we get

x = [ 7 ± √ ( 49 - 52 ) ] / 2

x = [ 7 ± √ ( -3 ) ] / 2

x = ( 7 ± √3i ) / 2

Therefore , the value of x = ( 7 ± √3i ) / 2

Hence ,

The solution to the equation is x = ( 7 + √3i ) / 2 and x = ( 7 - √3i ) / 2

Step-by-step explanation:

Answer:

-16x^9z^12

Step-by-step explanation:

you . multiply the exponents with the three in this type of equation.

For this case, we must indicate which of the given functions is not defined for[tex]x = 0[/tex]

By definition, we know that:

[tex]f (x) = \sqrt {x}[/tex] has a domain from 0 to infinity.

Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. For it to be defined, the term within the root must be positive.

Thus, we observe that:

[tex]y = \sqrt {x-2}[/tex] is not defined, the term inside the root is negative when [tex]x = 0[/tex].

While [tex]y = \sqrt {x + 2}[/tex] if it is defined for [tex]x = 0.[/tex]

[tex]f(x)=\sqrt[3]{x}[/tex], your domain is given by all real numbers.

Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. In the same way, its domain will be given by the real numbers, independently of the sign of the term inside the root.

So, we have:

[tex]y = \sqrt [3] {x-2}[/tex] with x = 0: [tex]y = \sqrt [3] {- 2}[/tex] is defined.

[tex]y = \sqrt [3] {x + 2}[/tex]with x = 0: [tex]y = \sqrt [3] {2}[/tex]in the same way is defined.

Answer:

[tex]y = \sqrt {x-2}[/tex]

Option b

The function that are undefined for (x=0) is  [tex]y = \sqrt[3]{x-2}[/tex] and [tex]y = \sqrt{x-2}[/tex] and this can be determined by putting (x=0) in all the given expressions.

Given :

Function 1 - [tex]y = \sqrt[3]{x-2}[/tex]

Function 2 - [tex]y = \sqrt{x-2}[/tex]

Function 3 - [tex]y = \sqrt[3]{x+2}[/tex]

Function 4 - [tex]y = \sqrt{x+2}[/tex]

Evaluate each function at (x = 0) to determine which function is undefined for (x = 0).

Function 1 - [tex]y = \sqrt[3]{x-2}[/tex]

put (x = 0) in above function:

[tex]y = \sqrt[3]{-2}[/tex]

Therefore, it can be concluded that the above function is not defined for (x=0).

Function 2 - [tex]y = \sqrt{x-2}[/tex]

put (x = 0) in above function:

[tex]y = \sqrt{-2}[/tex]

Therefore, it can be concluded that the above function is not defined for (x=0).

Function 3 - [tex]y = \sqrt[3]{x+2}[/tex]

put (x = 0) in above function:

[tex]y = \sqrt[3]{2}[/tex]

Therefore, it can be concluded that the above function is defined for (x=0).

Function 4 - [tex]y = \sqrt{x+2}[/tex]

put (x = 0) in above function:

[tex]y = \sqrt{2}[/tex]

Therefore, it can be concluded that the above function is defined for (x=0).

Let [tex]x[/tex] represents the depth of water from the water surface.

As we go down the water, the depth will be negative.

So, the depth could vary from 100 ft to 2500 ft.

The minimum depth should be 100 ft and the maximum depth is 2500 ft.

Answer:

-35%  

Step-by-step explanation:

To solve this equation, the first thing we have to do is to convert percentages to decimals because we are doing mathematical operations with a fraction.

To convert a percentage to a decimal, we just divide by 100. So, 60% equals 0.60, and 25% equals 0.25.

Next, we subtract these values from 1/2.

So, we have the following steps:

1. Calculate 1/2 - 0.60 (which is the decimal equivalent of 60%). This gives us -0.10.

2. Then subtract 0.25 (which is the decimal equivalent of 25%) from the result. So, -0.10 - 0.25 equals -0.35.

Therefore, 1/2 - 60% - 25% equals -0.35.
