The perimeter of the new garden after extension is 44 feet.

To find the perimeter of the new garden, we need to determine the dimensions after the extension. The original garden measures 3 feet by 15 feet, and the gardener decides to extend it by 1 foot in each direction. This means the new dimensions are 5 feet by 17 feet.

To find the perimeter, we add up all the sides of the rectangle. The formula for the perimeter of a rectangle is:

P = 2(l + w)

where P represents the perimeter, l represents the length of the rectangle, and w represents the width of the rectangle. Plugging in the values, we have:

P = 2(5 + 17) = 2(22) = 44 feet

Therefore, the perimeter of the new garden is 44 feet.

Answer:

  B. (6√2 + 12) inches

Step-by-step explanation:

The length of the kite edge at upper left is ...

  x/sin(45°) = x/(1/√2) = x√2

The length of the kite edge at upper right is ...

  x/sin(30°) = x/(1/2) = 2x

The perimeter of the kite is double the sum of the lengths of these edges:

  P = 2(x√2 +2x) = 2x(√2 +2)

For x=3 in, this is ...

  P = 2·(3 in)(√2 +2)

  P = (6√2 +12) in

_____

The sine of an angle is the ratio of the side opposite to the hypotenuse. Here, the side opposite is x, and the hypotenuse is the kite edge of interest.

  x/hypotenuse = sin(angle)

  hypotenuse = x/sin(angle) . . . . . solve for hypotenuse

To evaluate the line integral along the unit circle, we can parametrize the circle using x = cos(t) and y = sin(t). The resulting integral is 6 times the integral of cos squared(t) times cos(t).

To evaluate the line integral, we need to parametrize the unit circle. Let's use x = cos(t) and y = sin(t) as the parameterization. The differential arc length is given by ds = √(dx² + dy²) = dt. Substituting these into the line integral, we get:

∫(2cos³(t) - sin³(t)) dt + ∫(4cos³(t) + sin³(t)) dt = ∫(6cos³(t)) dt

Since the unit circle can be parameterized from 0 to 2π, the integral becomes:

∫[6cos³(t)] dt = 6 ∫[(cos(t))³] dt = 6 ∫[cos³(t)] dt = 6[∫(cos²(t)cos(t)) dt]

  D. This is the graph of the greatest integer function.

Step-by-step explanation:

The graph maps each x-value to the largest integer less than or equal to that value. That is the definition of the "greatest integer" function.

The "greatest integer" of -3.2 is -4, so B is not a correct choice. The graph does not pass the horizontal line test, so the function is not one-to-one, and E is not a correct choice.

Final answer:

To find the endpoints of the other diagonal of the rhombus, we can use the fact that diagonals of a rhombus bisect each other. The endpoints of the other diagonal are (-7, 7) and (-1, 3). Therefore, Option A is the correct answer.

Explanation:

To find the endpoints of the other diagonal of the rhombus, we can use the fact that diagonals of a rhombus bisect each other, meaning they intersect at their midpoints. We can find the midpoint by taking the average of the x-coordinates and the average of the y-coordinates of the given endpoints of the first diagonal.

For the given endpoints (-10, 1) and (2, 9), the midpoint would be ((-10 + 2)/2, (1 + 9)/2), which simplifies to (-4, 5).

Since the diagonals bisect each other, the other diagonal would have the same midpoint. Therefore, the endpoints of the other diagonal would be (-4, 5) and the reflection of (-4, 5) across the midpoint of the given diagonal, which is the midpoint of (-10, 1) and (2, 9). Thus, the correct answer is (-4, 5) and its reflection across (-4, 5), which is (-7, 7) and (-1, 3).

Answer:

1172.08 square inches

Step-by-step explanation:

Total surface area is area of all the surfaces.

Cylinder:

Top surface = πr^2 = π(4)^2 = 16(3.14) = 50.24

Lateral Surface = 2πrh = 2π(4)(9) = 72π = 72(3.14) = 226.08

Rectangular Prism:

2 sides = 2*(11*11) = 242

front and back = 2*(16*11) = 352

bottom = 16 * 11 = 176

Top part (it is top rectangle - bottom of cylinder) = (16*11) - (π(4)^2) = 125.76

Adding all up, we get:

50.24 + 226.08 + 242 + 352 + 176 + 125.76 = 1172.08 square inches

These have solution (r, s) = (40, 35).

Answer with explanation:

Temperature in the living room =68°F

The equation which satisfies ,the  room temperature t, in degrees Fahrenheit, m minutes after the thermostat is activated, satisfies

 t=2 Cos (0.21 m) +68----------(1)

⇒To determine the period of the function

Z= A cos (sx+q)+r

As period of cos x is 2 π.

So,the given function has period

        [tex]=\frac{2\pi}{s}[/tex]            

So, the period of function 1, is given by

        [tex]=\frac{2\pi}{0.21}[/tex]  

⇒The meaning of period of the function is that after every period of   [tex]=\frac{2\pi}{0.21}[/tex] the temperature of the room increases or decreases by an integer equal to 2.

⇒Cosine function has maximum value of 1 , and Minimum value of -1.

-1 ≤ Cos x ≤ 1

So, the Maximum value of function = 2 ×1+68°=70°----Maximum Temperature

And, the minimum value of function = 2 ×(- 1)+68°=66°----Minimum Temperature

Final answer:

The period of the cosine function used to model the room temperature controlled by a thermostat is about 29.9155 minutes. This is the time it takes for the temperature to complete one full cycle of oscillation between the maximum of 70°F and the minimum of 66°F.

Explanation:

Felicity set the thermostat in her living room to 68°F. The room temperature t, in degrees Fahrenheit, m minutes after the thermostat is activated, satisfies t = 2cos(0.21m) + 68. This function describes a cosine wave, typical for oscillator systems like a thermostat regulating room temperature. To determine the period of the function, we examine the cosine part of the equation.

The general form of a cosine function is y = A cos(Bx + C) + D, where the period is 2π/B. Here, A is the amplitude, B affects the period, C is the phase shift, and D is the vertical shift. In Felicity's thermostat function, B = 0.21. The period of the function is therefore 2π/0.21, which is approximately 29.9155 minutes. This period represents the time it takes for the room temperature to go from a maximum value back to that value again after one complete cycle.

The max temperature is 2 + 68 = 70°F, and the min temperature is -2 + 68 = 66°F. These represent the highest and lowest temperatures the room will reach with the current thermostat settings.

Hey there! Thanks for asking your question here on Brainly.

First, we can factor a 5 out of each term in the trinomial. This leaves us with: 5(12x^2 - 31x + 20)

Second, we need to multiply 12 * 20 and find a factor pair of the product, 240, which equals -31. This factor pair would be -15 and -16. This now leaves us with: 5((12x^2 - 16)(-15x + 20))

Third, we need to simplify each binomial in parenthesis. By doing so, what is left inside of each parenthesis should be the same if this step is done correctly. This leaves us with: 5(4x(3x - 4)-5(3x - 4))

Fourth and finally, we construct our new factored trinomial! The outside number stays, as well as one of the inner parenthesis binomials. Use the terms you factored out of the parenthesis in step three to construct another

binomial. This leaves us with: 5(4x - 5)(3x - 4) and the correct answer is C.

Step-by-step explanation:

In his last 30 throws, Tom hit the target 20 times and missed 10 times.

p = probability he misses the target = ⅓

q = probability he hits the target = ⅔

Using binomial probability:

P = nCr (p)^r (q)^(n-r)

Given n = 3, r = 1, p = ⅓, and q = ⅔:

P = ₃C₁ (⅓)¹ (⅔)³⁻¹

P = (3) (⅓) (⅔)²

P = 4/9

There is a 4/9 probability that he misses exactly 1 of his next 3 throws.

By applying binomial probability, the estimated probability that exactly one (1) out of the next three (3) throws doesn't hit the target is 4/9.

In order to determine the estimated probability that exactly one (1) out of the next three (3) throws doesn't hit the target, we would apply binomial probability equation:

[tex]P =\; ^nC_r (p)^r (q)^{(n-r)}[/tex]

Based on the information given, we can deduce the following points:

Substituting the given parameters into the equation, we have;

P = ³C₁ × (⅓)¹ × (⅔)³⁻¹

P = 3 × (⅓)¹ × (⅔)²

P = 3 × ⅓ × (⅔)²

P = 1 × 4/9

P = 4/9.

* Lets explain what is the a difference of two squares

- If we multiply two binomial and the answer just two terms with

 negative sign between them and the two terms are square numbers

 we called this answer a difference of two squares

- Examples

# (a + b)(a - b)

- Lets multiply them

∵ (a × a) + (a × -b) + (b × a) + (b × -b)

∴ a² - ab + ba - b²

- Add the like term

∵ ab = ba

∴ -ab + ba = 0

∴ (a + b)(a - b) = a² - b² ⇒ difference of two squares

- From above the difference of two squares appears when we

 multiply sum and difference of the same two terms

# (a + b) ⇒ is the sum of a and b

# (a - b) ⇒ is the difference of a and b

* Now lets solve the problem

- In (5z + 3)(-5z - 3)

∵ (5z + 3) ⇒ is the sum of 5z and 3

∵ (-5z - 3) ⇒ is the difference of -5z and 3

∵ 5z ≠ - 5z

∴ They are not the sum and difference of the same two terms

∴ The product result not in a difference of squares

- In (w - 2.5)(w + 2.5)

∵ (w - 2.5) is the difference between w and 2.5

∴ (w + 2.5) is the sum of w and 2.5

∴ They are the sum and difference of the same two terms

∴ The product result in a difference of squares

- In (8g + 1)(8g + 1)

∵ The two brackets are the sum of 8g and 1

∴ They are not the sum and difference of the same two terms

∴ The product result not in a difference of squares

- In (-4v - 9)(-4v + 9)

∵ (-4v - 9) is the difference between -4v and 9

∵ (-4v + 9) is the sum of -4v and 9

∴ They are the sum and difference of the same two terms

∴ The product result in a difference of squares

- In (6y + 7)(7y - 6)

∵ (6y + 7) is the sum of 6y and 7

∵ (7y - 6) is the difference between 7y and 6

∵ 6y ≠ 7y and 7 ≠ 6

∴ They are not the sum and difference of the same two terms

∴ The product result not in a difference of squares

- In (p - 5)(p - 5)

∵ The two brackets are the difference of p and 5

∴ They are not the sum and difference of the same two terms

Answer:

D. 9

Step-by-step explanation:

The Pythagorean triple for a 30-60-90 right triangle is (x, x√3, 2x).  The side across from the 30° angle is x, the side across from the 60° angle is x√3, and the side across from the right angle is 2x (which is also the hypotenuse).  If the side across from the 60° angle is given as 9√3, we can set that equal to the identity for that leg:

9√3 = x√3 and solve for x.  Divide both sides by the √3 to get that x = 9

Answer:

The correct answer is option D. 9

Step-by-step explanation:

Points to remember

It a right triangle with angles 30°, 60 and 90° the n the sides are in the ratio,

Shorter leg : longer leg : hypotenuse = 1 : √3 : 2

To find the length of shorter leg

Here it is given that, longer length = 9√3

We have,

Shorter leg : longer leg : hypotenuse = 1 : √3 : 2 =  Shorter leg : 9√3: hypotenuse

Therefore shorter leg = 9√3/√3 = 9
