A rectangle that could have a perimeter of 52 feet is a 12 feet by 14 feet rectangle.

The symbols W and L are variables.

The symbol P is a constant.

In Mathematics and Geometry, the perimeter of a rectangle can be calculated by using this mathematical equation (formula);

P = 2(L + W)

Where:

By substituting the given side lengths into the formula for the perimeter of a rectangle, we have the following;

P = 2(L + W)

52 = 2(12 + 14)

52 = 2(26)

52 feet = 52 feet.

Answer:

F(-x) = 0

Step-by-step explanation:

What is F(-x)?

F(-x) = F(-1)

F(x) = x³ + 1                              F(-1)

F(-1) = -1³ + 1

F(-1) = -1 + 1

F(-1) = 0

So, F(-x) = 0

Answer:

f(-1) = 0

Step-by-step explanation:

Evaluating a function for f(-x) is the same as evaluating it for f(-1).

So we plug in -1 instead.

f(-1) = x³ + 1  

      = (-1)³ + 1 (here we cube -1)

      = -1 + 1     (here we subtract)

      = 0           (and, this is the answer)

\(\therefore\) The answer is f(-1) = 0

Answer:

  your marked choice is correct: x = e

Step-by-step explanation:

For the line to go through the origin, the ratio of ln(x) to x at the point must equal the slope at the point.

The slope of ln(x) is 1/x, so we require ...

  ln(x)/x = 1/x

  ln(x) = 1 . . . . . . multiply by x

  x = e . . . . . . . . take antilogs

The missing sides of the figure are

3. x = 6

5. x = 40

3. Given that the area is 42

Area of trapezoid is = 1/2 (sum of parallel lines) * height

8 = 1/2 (x + 10)

16 = (x + 10)

Answer:

6 ft < L₃ < 30 ft

Step-by-step explanation:

To obtain the answer to the question given above, we must bear in mind that:

The sum of the length of two sides of any triangle is always greater than the 3rd length i.e

L₁ + L₂ > L₃

With the above information in mind, we can obtain the answer to the question given above as follow:

Length 1 (L₁) = 12 feet

Length 2 (L₂) = 18 feet

Length 3 (L₃) =..?

Case 1:

L₁ + L₂ > L₃

12 + 18 > L₃

30 > L₃

L₃ < 30 feet

Case 2:

L₁ + L₃ > L₂

12 + L₃ > 18

Collect like terms

L₃ > 18 – 12

L₃ > 6 feet

Thus,

6 feet < L₃

Combining case 1 and 2,we obtained:

6 ft < L₃ < 30 ft

Therefore, the possible Lenght of the 3rd side is : 6 ft < L₃ < 30 ft

Answer:

The radius of the circle is 24.5 units

Step-by-step explanation:

The formula for the circumference of a circle is \(C=2\pi r\)

Where \(C\) is the circumference and \(r\) is the radius.

Lets solve for \(r\).

Divide both sides of the equation by \(2\pi\).

\(\dfrac{C}{2\pi}=r\)

Now we have an equation to evaluate the radius.

Numerical Evaluation

In this example we are given

\(C=153.86153\\\pi =3.14\)

Substituting our values into our equation for the radius yields

\(r=\dfrac{153.86153}{2*3.14}\)

\(r=\dfrac{153.86153}{6.28}\)

\(r=\dfrac{153.86153}{6.28}\)

\(r=24.5\)

Part a: Probability Americans drink coffee or drink tea = 0.50.

Part b: Conditional probability: 2/3.

Part a: Probability, Americans drink coffee or drink tea.

P(C∪T) = P(C) + P(T) - P(C∩T)

P(C∪T) = 0.40 + 0.30 - 0.20

P(C∪T) = 0.50

Part b: They are more likely to consume coffee if they also drink tea.

P(C | T) = P(C∩T)/P(T)

P(C | T) = 0.20/0.30

P(C | T) = 0.20/0.30

P(C | T) = 2/3

Thus, the conditional probability they drink coffee given that they drink tea is 2/3.

If circle with center N with m∠MNP=124 ∘ and MN=13,  the area of sector MNP is approximately equal to 194.86 square units.

To find the area of a sector of a circle, we need to use the formula:

Area of sector = (central angle/360°) x πr²

Where r is the radius of the circle.

In this problem, we know that the central angle m∠MNP is 124° and MN, which is also the radius of the circle, is 13. So we can substitute these values into the formula:

Area of sector = (124/360) x π(13)²

Area of sector ≈ 194.86

Therefore, the area of sector MNP is approximately equal to 194.86 square units.

The sketch for slope is attached below.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Step-by-Step explanation:

hihi your problem is a system of question y = x-4 and  y = -x+6 okay so  graph them both normally and then find the point where they intersect which is gonna be a coordinate point, and that's your solution !!

y = x-4
the y intersect is going to be 4
the slope is a positive 1 , going up to the right, through the positive quadrant, line is facing to the right

y = -x+6
the y intersect is going to be -6
the slope is going to be a -1 , following up the opposite way the line is going to face the left

once you graph them both you'll see the point of intersection, the solution
make sure you drew your lines very clearly !!!!

the solution is  x = 5 and y = 1 which is also (5 , 1)

One egg contains 17.88 mg of cholesterol, one cupcake contains 83.33 mg of cholesterol, and one slice of pizza contains 27.22 mg of cholesterol.

What is the linear equation?

Linear equations are the equations of degree 1. It is the equation for the straight line. The standard form of linear equation is ax+by+c =0, where a ≠ 0 and b ≠ 0.

Let's call the amount of cholesterol in one egg "x".

Then, the amount of cholesterol in one cupcake is "y" and the amount of cholesterol in one slice of pizza is "z".

From the first statement, we can set up the equation:

x + y + z = 302

From the second statement, we can set up another equation:

3y + 4z = 89

And from the third statement, we can set up a third equation:

3x + y = 844

Now we have three equations with three unknowns, so we can solve for the values of x, y, and z.

Starting with the third equation:

3x + y = 844

y = 844 - 3x

Next, we can substitute this expression for y in the first equation:

x + (844 - 3x) + z = 302

4x + z = -542

z = -542 - 4x

Finally, we can substitute these expressions for y and z in the second equation:

3y + 4z = 89

3(844 - 3x) + 4(-542 - 4x) = 89

2532 - 9x + -2168 - 16x = 89

536 - 25x = 89

25x = 536 - 89

25x = 447

x = 17.88

Hence, one egg contains 17.88 mg of cholesterol, one cupcake contains 83.33 mg of cholesterol, and one slice of pizza contains 27.22 mg of cholesterol.
