If an arc with a measure of 34 degrees has a length of 38pi inches, what is the circumference of the circle?

Answer:

x = 19m

Step-by-step explanation:

to find the other two sides of the compound shape,

(2+6+6)= 14m , and (x-2)m

area of the compound shape = (2 x 14) + 2(x-2) =28 + 2x - 2 = 2x+26 m²

area of square = 8 x 8 = 64 m²

the question states that these two shapes have the same area,

2x + 26 = 64

2x = 38

x = 38/2

x= 19m

The flag have 6.09 square feet of area that make up the red and blue portion. And the flag have 1.35 square feet more of the white portions than the red and blue portions.

The tripes can be observed to have the shape of trapezoids, the middle coloured stripe can be split into two smaller trapezoids while the top and bottom coloured are of same size.

Red and blue portions:

1/2 × (3.5 + 4.5) × 0.6 = 2.4 ft² {area of trapezoid}

top

top and bottom coloured stripe = 2 × 2.4 ft² = 4.8 ft²

1/2 × (1.9 + 2.4) × 0.3 = 0.645 ft²

middle coloured stripe = 2 × 0.645 ft² = 1.29 ft²

area of red and blue portions = 4.8 ft² + 1.29 ft² = 6.09 ft²

White portions:

area of white triangle portion = 1/2 × 3 × 2.6 = 3.9ft²

1/2 ×( 2.4 + 3.5) × 0.6 = 1.77 ft² {area of one white stripe trapezoid}

area of white stripes = 2 × 1.77 ft² = 3.54 ft²

white portions = 3.9ft² + 3.54 ft² = 7.44 ft²

In conclusion, the flag have 6.09 square feet of area that make up the red and blue portions. And the flag have 1.35 square feet more of the white portions than the red and blue portions.

Answer:

The chord length x is growing at a rate of 1 m/min after 2π minutes.

Step-by-step explanation:

The formula for chord length x in terms of radius r is:

[tex]\boxed{x &= 2r\sin\left(\dfrac{\theta}{2}\right)}[/tex]

where θ is the central angle subtended by the chord.

The formula for arc length s in terms of radius r is:

[tex]\boxed{s=r\theta}[/tex]

where θ is the central angle subtended by the chord.

Rearrange the formula for arc length to isolate θ, then substitute this into the the formula for chord length to create an equation for x in terms of s:

[tex]\begin{aligned}\theta=\dfrac{s}{r} \implies x &= 2r\sin\left(\dfrac{\frac{s}{r}}{2}\right)\\x&= 2r\sin\left(\dfrac{s}{2r}\right)\end{aligned}[/tex]

Given the radius is 6 m, substitute r = 6 into the equation for x:

[tex]\implies x &= 12\sin\left(\dfrac{s}{12}\right)[/tex]

Differentiate with respect to s:

[tex]\begin{aligned}\implies \dfrac{\text{d}x}{\text{d}s} &= \dfrac{1}{12} \cdot 12\cos\left(\dfrac{s}{12}\right)\\\\&=\cos\left(\dfrac{s}{12}\right)\end{aligned}[/tex]

Given the arc length s is growing at a rate of 2 m/min:

[tex]\implies \dfrac{\text{d}s}{\text{d}t}=2[/tex]

Use the chain rule to create an equation for the rate of change of the chord x:

[tex]\begin{aligned}\implies \dfrac{\text{d}x}{\text{d}t}&=\dfrac{\text{d}x}{\text{d}s}\times \dfrac{\text{d}s}{\text{d}t}\\\\&=\cos\left(\dfrac{s}{12}\right) \times 2\\\\&=2\cos\left(\dfrac{s}{12}\right) \end{aligned}[/tex]

Given the arc length is growing at a rate of 2 m/min:

[tex]\implies \dfrac{\text{d}s}{\text{d}t}=2[/tex]

Integrate to create an equation for s in terms of t:

[tex]\begin{aligned}\displaystyle \int 1 \; \text{d}s&=\int 2\; \text{d}t}\\\\ s&=2t+\text{C}\end{aligned}[/tex]

Given s = 0 when t = 0, this means that C = 0. Therefore:

[tex]\implies s=2t[/tex]

If t = 2π then:

[tex]\implies s=2 \cdot 2\pi = 4\pi[/tex]

Finally, substitute s = 4π into the equation to calculate the rate of change of the chord at 2π minutes:

[tex]\begin{aligned}\implies \dfrac{\text{d}x}{\text{d}t}&=2\cos\left(\dfrac{4\pi}{12}\right) \\\\&=2 \cos \left(\dfrac{\pi}{3}\right)\\\\&=2 \cdot \dfrac{1}{2}\\\\&=1\end{aligned}[/tex]

Therefore, the chord length x is growing at a rate of 1 m/min after 2π minutes.

The scale factor of the dilation that was done for the considered triangle is given by: Option C: 4

How does dilation works?

Dilation of a figure will leave its sides get scaled (multiplied) by same number.  That number is called the scale factor of that dilation.

It's also called scaling of a figure, but due the involvement of coordinates, it involves a center of a dilation, which is like a pinned point which stays at same place after dilation.

It's like we enlarge or shorten the size of the figure (or keep it same, when scale factor = 1).

For this case, we are specified that:

Larger triangle is dilation of the smaller triangle.

The center of the dilation is (1,-1).

From graph, we see that the base of smaller triangle is of 2 units.

The base of the larger triangle is of 8 units.

Let the scale factor of dilation be 's'.

Then we have:

length of base of dilated triangle = s × length of base of original triangle

or

Step-by-step explanation:

Let's work backwards from the information we have to determine which diagram Ronald drew.

We know that after Ronald ate on Tuesday, there was 1/2 of the pizza remaining. This means that he ate 1/2 of the pizza on Tuesday, since he had eaten 1/3 of the pizza on Monday.

So, if we add 1/2 and 1/3, we get:

1/2 + 1/3 = 5/6

This means that Ronald ate 5/6 of the pizza in total. We also know that he ate 1/2 of the pizza on Tuesday, so the fraction he ate on Monday was:

5/6 - 1/2 = 1/3

This confirms that Ronald ate 1/3 of the pizza on Monday.

Now, let's look at the answer choices. We need to find a diagram that represents Ronald eating 1/2 of the pizza, since that's what he ate on Tuesday. The only answer choice that represents 1/2 of the pizza shaded is B. 2/3.

Answer:

Step-by-step explanation:

The expected value of the distribution is 1 and the probability that a randomly selected student completes fewer than 2 bonus assignments is 0.75

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

a. To compute the expected value of the distribution, we need to multiply each possible number of completed bonus assignments by its probability and then add up the results. That is:

Expected value = (0 x 0.55) + (1 x 0.2) + (2 x 0.15) + (3 x 0.1) = 0 + 0.2 + 0.3 + 0.3 = 1.0

Therefore, the expected value of the distribution is 1.0.

b. To find the probability that a randomly selected student completes fewer than 2 bonus assignments, we need to add up the probabilities for the cases where x is 0 or 1. That is:

P(x < 2) = P(x=0) + P(x=1) = 0.55 + 0.2 = 0.75

Therefore, the probability that a randomly selected student completes fewer than 2 bonus assignments is 0.75 or 75%.

The additional cost incurred in dollars when production is increased from 12 units to 15 units is -$2.28.

To find the additional cost incurred in dollars when production is increased from 12 units to 15 units, we need to calculate the difference in the marginal cost between these two production levels.

Given the marginal cost function: C′(x) = 0.12x^2 − 4x + 140

We can substitute x = 12 into the marginal cost function to find the marginal cost at 12 units:

C′(12) = 0.12(12)^2 − 4(12) + 140

C′(12) = 0.12(144) − 48 + 140

C′(12) = 17.28 − 48 + 140

C′(12) = 109.28

Similarly, we can substitute x = 15 into the marginal cost function to find the marginal cost at 15 units:

C′(15) = 0.12(15)^2 − 4(15) + 140

C′(15) = 0.12(225) − 60 + 140

C′(15) = 27 − 60 + 140

C′(15) = 107

Now, we can calculate the difference in marginal cost between 15 units and 12 units. The Additional cost wil be:

= C′(15) - C′(12)

= 107 - 109.28

x = [tex]\sqrt{2}[/tex]  (or)  x = [tex]\frac{-3\sqrt{2}}{5}[/tex]

The quadratic equation can be solved to give the value of x1 = √2 and x2 = -3√2 / 5.

To solve the quadratic equation 5x² - 2√2x - 6 = 0, we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

Now we have two solutions, one for the positive value and one for the negative value:

x1 = (2√2 + 8√2) / 10

x2 = (2√2 - 8√2) / 10

Simplify the solutions:

Step-by-step explanation:

We know that the formula for perimeter (P) is P = 2w + 2l

Because we're told that the length (l) is 4 feet more than the width (w), our formula for length is l = w + 4

We can now substitute w + 4 for l in the perimeter formula and 28 for P.  This will allows us to first solve for the width:

[tex]28 = 2(w+4)+2w\\28=2w+8+2w\\28=4w+8\\20=4w\\5=w[/tex]

Now we can plug in 5 for w in our length formula to find the length:

[tex]l = 5 + 4\\l = 9[/tex]

We can check our solutions by plugging in 5 for w and 9 for l in the perimeter formula and check whether we get 28 as an answer:

The minimum cost is achieved when we use 14 pounds of deluxe coffee and 35 pounds of regular coffee.

Let x be the number of pounds of deluxe coffee to be used in the blend, and let y be the number of pounds of regular coffee to be used in the blend.

We are told that the blend must contain at least 14 pounds of deluxe coffee, so we have the inequality:

We are also told that the total amount of blend must be at least 49 pounds, so we have the inequality:

To minimize costs, we need to minimize the cost function C(x,y), which is the total cost of the blend. The cost of deluxe coffee is $6 per pound, and the cost of regular coffee is $4 per pound, so we have:

Now we can use the method of Lagrange multipliers to find the minimum value of C(x,y) subject to the two constraints above. We define the Lagrange function L as follows:

where λ and μ are Lagrange multipliers. We need to find the values of x, y, λ, and μ that minimize L.

Taking partial derivatives of L with respect to x, y, λ, and μ, and setting them equal to zero, we get the following system of equations:

From the second equation, we get λ = 4. Substituting this into the first equation, we get μ = 2. Substituting these values into the third equation, we get y = 35. Substituting μ = 2 into the fourth equation, we get x = 14.

Answer:

the coordinates of point P are (15, 19 + 3 sqrt(3)).

Step-by-step explanation:

Let's first find the center of the circle, which is (h, k). From the given information, we know that h = 12 and k = 16.

Next, we need to find the coordinates of the point P. We can do this using the formula for finding a point on a circle given its center and angle:

x = h + r cos(theta)

y = k + r sin(theta)

where r is the radius of the circle and theta is the angle between the horizontal axis and the line connecting the center of the circle to the point P.

Substituting the given values, we have:

x = 12 + 6 cos(pi/3)

y = 16 + 6 sin(pi/3)

Evaluating the trigonometric functions, we get:

x = 12 + 6 (1/2) = 15

y = 16 + 6 (sqrt(3)/2) = 19 + 3 sqrt(3)

Therefore, the coordinates of point P are (15, 19 + 3 sqrt(3)).
