Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

The countertop is  8.37 square metersStep-by-step explanation:LetL > the length of the countertopW > the width of the countertopwe know

Answer:

19.83 square meters

Step-by-step explanation:

So, if we are finding the area of a rectangular countertop, we need to multiply the length by the width.          A=lw    l=length    w=width

First, we multiply the length and width of the countertop (13 and 5).

13x5=65 square feet              65 is the area of thecountertop in feet.

Next, we have to multiply that by 0.305 to convert it into meters.

65*0.305=19.825 square meters       If we round it, its 19.83 square meters.

Step-by-step explanation:

HOPE IT HELPS :)

Well let's say that to compare these two numbers, we have to start with the definition first.

Definition

\( \displaystyle \large{ {y}^{2} = x} \\ \displaystyle \large{ y = \pm \sqrt{x} }\)

Looks like we can use any x-values right? Nope.

The value of x only applies to any positive real numbers for one reason.

As we know, any numbers time itself will result in positive. No matter the negative or positive.

Definition II

\( \displaystyle \large{ {a}^{2} = a \times a = |b| }\)

Where b is the result from a×a. Let's see an example.

Examples

\( \displaystyle \large{ {2}^{2} = 2 \times 2 = 4} \\ \displaystyle \large{ {( - 2)}^{2} = ( - 2) \times ( - 2) = | - 4| = 4}\)

So basically, their counterpart or opposite still gives same value.

Then you may have a question, where does √-1 come from?

It comes from this equation:

\( \displaystyle \large{ {y}^{2} = - 1}\)

When we solve the quadratic equation in this like form, we square both sides to get rid of the square.

\( \displaystyle \large{ \sqrt{ {y}^{2} } = \sqrt{ - 1} }\)

Then where does plus-minus come from? It comes from one of Absolute Value propety.

Absolute Value Property I

\( \displaystyle \large{ \sqrt{ {x}^{2} } = |x| }\)

Solving absolute value always gives the plus-minus. Therefore...

\( \displaystyle \large{ y = \pm \sqrt{ - 1} }\)

Then we have the square root of -1 in negative and positive. But something is not right.

As I said, any numbers time itself of numbers squared will only result in positive. So how does the equation of y^2 = -1 make sense? Simple, it doesn't.

Because why would any numbers squared result in negative? Therefore, √-1 does not exist in a real number system.

Then we have another number which is -√1. This one is simple.

It is one of the solution from the equation y^2 = 1.

\( \displaystyle \large{ {y}^{2} = 1} \\ \displaystyle \large{ \sqrt{ {y}^{2} } = \sqrt{1} } \\ \displaystyle \large{ y = \pm \sqrt{1} }\)

We ignore the +√1 but focus on -√1 instead. Of course, we know that numbers squared itself will result in positive. Since 1 is positive then we can say that these solutions exist in real number.

Conclusion

So what is the different? The different between two numbers is that √-1 does not exist in a real number system since any squared numbers only result in positive while -√1 is one of the solution from y^2 = 1 and exists in a real number system.

Answer:

Therefore \(\sqrt{1} \neq -\sqrt{1}\)

Step-by-step explanation:

\(\sqrt{-1} \\\) cannot be calculated as no two identical numbers that are multiplid could give -1. However - \(\sqrt{1}\) means -1 x \(\sqrt{1}\) = -1 x 1 = -1 . Therefore \(\sqrt{1} \neq -\sqrt{1}\)

Answer:3.25 mph and 1.25 mph

Step-by-step explanation:

Let s - speed in still water, c - speed of current.

We have the following equations:

2(s + c) = 9

2(s - c) = 4

Simplify:

s + c = 4.5

s - c = 2

Add up and solve for s:

2s = 4.5 + 2

2s = 6.5

s = 6.5/2

s = 3.25 mph

Find c:

c = 3.25 - 2 = 1.25 mph

Answer: 5 with an open circle facing the right.

Step-by-step explanation:

First: you need to know the difference between closed and open circles. Closed means less than or equal to/ greater than or equal to while an open circle just means less than/ greater than.

Second: To know if it will be facing left or right is very simple. It is just if the number is increasing or decreasing in your problem. If increasing it goes right if decreasing it goes left. In this case, the number increases each day so it will face the right.

Third: To start the problem you subtract the number of shells she has already (34) by how many she needs (100) which is 66. then divide 66 by the number of seashells they get a day (12) which would give you 5.5

Fourth: I'm going to guess that you can't do decimals on the graph so all you have to do is put an open circle with the arrow facing the right meaning everything after this point, not including the number it is on.

Answer:

d  ≥  7

Step-by-step explanation:

A closed dot means you CAN use the number in the equality (greater than and equal to or less than and equal to). An OPEN dot means it's just greater than or less than, no equal to. Positive numbers GROW to the right so if the line is going that way it means greater than or greater than and equal to. The same is true for the left side. The left side makes numbers get SMALLER which means less than or less than and equal to. Your problem has a closed dot and an arrow to the right so the inequality is d  ≥  7.

Answer:

1. 678.6

2. 1131

3. 490.1

4. 1809.6

Step-by-step explanation:

A=2πrh+2πr2

Answer:

1.  SA = 216π cm² ≈ 678.24cm²

2. SA = 360π ft²≈ 1130.40ft²

3. SA = 156π yd² ≈ 489.84yd²

4. SA = 576π m² ≈ 1808.64 m²

Step-by-step explanation:

SA of a cylinder = 2πrh + 2πr²

1.  r = diameter ÷ 2

  r = 12/2 = 6

   SA = 2π(6)(12) + 2π(6)²

   SA = 144π + 72π

   SA = 216π ≈ 678.24

2. r = 19/2 = 9

   SA = 2π(9)(11) + 2π(9)²

   SA = 198π + 162π

   SA = 360π ≈ 1130.40

3.  SA = 2π(6)(7) + 2π(6)²

    SA = 84π + 72π

    SA = 156π ≈ 489.84

4. r = 24/2 = 12

    SA = 2π(12)(12) + 2π(12)²

    SA = 288π + 288π

    SA = 576π ≈ 1808.64

The mathematical expression can be written as 6t, 2.6t, and 4.2t.

Answer:

845 miles

Step-by-step explanation:

First let us find the speed ( rate ) using the below formula.

\(\sf Speed=\frac{Distance \:\:travellled}{Time\:\:Taken}\)

\(\sf Speed=\frac{585 \:miles}{9 \:h}\)

\(\sf Speed=65\:miles\: per\: hour\)

They also said that, at the same speed he traveled for 13 hours.

So, now we have to find the distance.

For that, you can use the same formula by making the distance as the subject.

Let us find it now.

To find out how many pages each person reads in one hour, we can use the unit rate, the number of pages read per hour.

Jeff read 10(3/4) pages in 1/2 hour.

To find out how many pages he would read in one hour, we can multiply the number of pages he read by the fraction 2/1, which gives:

= 21 pages per hour

Jeff read 21 pages in one hour.

Kaley read 12(1/4) pages in 1/3 hour.

To find out how many pages she would read in one hour, we can multiply the number of pages she read by the fraction 3/1, which gives:

Answer:

Step-by-step explanation:

Challenge 1

We have exponential decline if 0 b 1. As you move from left to right, the curve will get less steep.

If b is greater than 1, exponential growth is present, and the curve slopes upward from left to right.

Examples include exponential decline (y = 2(0.5)x) and exponential growth (y = 2(1.2)x).

Remember that b cannot be negative.

===========================================

Challenge 2

In the general template provided, enter x = 0.

y = a(b)^x

y = a(b)^0

y = a(1) (1)

y = a

When x = 0 is plugged in, the result is y = a.

The curve is therefore on the point (0,a). The y intercept appears here. It is the point when the curve veers off the y axis. The y intercept is altered if the value of "a" is altered.
