The Surface area of the whole cone is 4408.56 cm²

The Surface area of the tips that is removed is  376.8 cm²

The Surface area of the megaphone(hollow) is  2712.96 cm²

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape.

Therefore,

Surface area of the whole cone = πr² + πrl

Therefore,

Surface area of the whole cone = πr(r + l)

where

Surface area of the whole cone = 3.14 × 18(18 + 60) = 4408.56 cm²

Surface area of the tips that is removed = 3.14 × 4 (18 + 12) = 376.8 cm²

Surface area of the megaphone(hollow) = πrl

Surface area of the megaphone(hollow) = 3.14 × 18 × (60 - 12) = 2712.96 cm²

Step-by-step explanation:

5.5 cm

Step-by-step explanation:

Let x be the width of the rectangle.

Since the length is double the width, the length would be 2x.

x can be found by solving the perimeter equation. The perimeter of the rectangle can be found by the equation:

\(p = 2(l + w)\)

\(33 = 2(2x + x)\)

\(33 \div 2 = (2x + x)\)

\(16.5 = 3x\)

\(16.5 \div 3 = x\)

\(5.5 = x\)

Therefore, the width of the rectangle is 5.5 cm.

Answer:

x = 3

Step-by-step explanation:

Because the endpoints of the segment with length 12.5 are the midpoints of the sides of the large trapezoid, the length of that segments, 12.5, is the average of the lengths of the top and bottom lengths of the large trapezoid.

(3x + 1 + 15)/2 = 12.5

Multiply both sides by 2.

3x + 16 = 25

3x = 9

x = 3

An equation that could be used to determine M, the unknown side length of the logo is X = (36/5) x M

Let's assume that the unknown side length of the logo is 'M'. The logo is a rectangle, and the area of a rectangle is given by multiplying its length and width. Since we know the length of the logo is 7(1)/(5) feet, we can write the equation:

A = L x W

where A is the area of the logo, L is the length of the logo, and W is the width of the logo.

Substituting the given values, we get:

A = (7(1)/(5)) x M

or

A = (36/5) x M

Now, we know that the area of the logo is exactly the maximum area allowed by the building owner. Let's assume this maximum area is 'X'. So, we can write another equation:

A = X

Combining both equations, we get:

X = (36/5) x M

This is the required equation that could be used to determine the unknown side length 'M' of the logo if we know the maximum area allowed by the building owner 'X'.

Answer:

The correct option is c.

Step-by-step explanation:

The margin of error is the range of values lower than and more than the sample statistic in a confidence interval. It is the number of percentage point by which the sample result will differ from the population result.

The general formula to margin of error is:

\(MOE=CV\times\frac{SD}{\sqrt{n}}\)

Here,

CV = critical value

SD = standard deviation

n = sample size

Now, if the computed minimum sample size needed for a particular margin of error is not a whole number, then round the value of n up to the next larger whole number.

Thus, the correct option is c.

Explanation:

Given zero's of a polynomial function:

Answer:

y = x² + 5x - 14

Step-by-step explanation:

If the zeros of a polynomial are 2 and -7, then:

⇒ x = 2  ⇒  (x - 2) = 0

⇒ x = -7  ⇒  (x + 7) = 0

Therefore, we can write the polynomial as:

y = a(x - 2)(x + 7)   where a is some constant

As the first term of the given polynomial is x², we can say that its coefficient is 1.  Therefore, a = 1

⇒ y = 1(x - 2)(x + 7)

⇒ y = (x - 2)(x + 7)

To write the polynomial in standard form  ax² + bx + c

simply expand the brackets:

⇒ y = (x - 2)(x + 7)

⇒ y = x² + 7x - 2x - 14

⇒ y = x² + 5x - 14

The length of the longer wire is 82 feet.

Let's denote the length of the longer wire as L. According to the given information, the shorter wire is attached to the ground 16 feet from the base of the pole, and the longer wire is attached to the ground 32 feet from the base of the pole.

We can form two similar right triangles using the wires. The height of each triangle is the height of the pole, and the base of each triangle is the distance from the base of the pole to where the wire is attached to the ground.

In the first triangle, the shorter wire creates an angle with the ground. Let's denote this angle as θ. Since we are given the cosine of this angle, we can use the cosine function to find the height of the pole in terms of θ and the base of the triangle:

cos(θ) = adjacent/hypotenuse = 16/L

Given that cos(θ) = 8/41, we can substitute this value into the equation:

8/41 = 16/L

To solve for L, we can cross-multiply and solve for L:

8L = 41 * 16

L = (41 * 16)/8

L = 82

Therefore, the length of the longer wire is 82 feet.

In summary, the length of the longer wire is 82 feet, as determined by using the cosine of the angle formed by the shorter wire and the ground, and considering the similarity of the triangles formed by the wires and the pole.

Answer:

\(\sqrt{(-\frac{806}{94}+8)^2+(-\frac{215}{94}-9)^2+ (-\frac{251}{94}-8)^2}\) Whatever this number may be

Step-by-step explanation:

The distance will be on the plane containing the point, and perpendicular to the line - which exists as long as the point doesn't sit on the line, but in that case our distance will simply be zero. Good news, since the line is given in parametric equation, the equation of the plane is easy to write by simply computing the dot product between the vector generating the line - or any multiple of it! - and the vector joining a random point x y z of the space with our given point, and setting it equal to zero. The equation of our plane is thus

\(6(x-(-8)) + 3(y-9) -7(z-8) = 0\\6(x+8)+3(y-9)-7(z-8)=0\)

We could multiply now or later, doesn't matter, so let's wait. Now, we need to know when the line passes through the plane, so let's plug the (parametric) coordinate of the line and let's see for which value of t that happens:

\(6(-2-6t+8) +3(1-3t -9) -7(-5+7t-8) =0\\6(6-6t) -3(8+3t)+7(13-7t)=0\\36-36t-24-9t+91-49t = 0\\t=103/94\)

Found this value of t, we can use it to find the coordinate of the point in common between the line and the plane:

\((-2-6\frac {103}{94};1-3\frac {103}{94}; -5+7\frac {103}{94}) = (-\frac{806}{94};-\frac{215}{94};-\frac{251}{94})\)

At this point it's simply a matter of calculating the distance between two points in 3D space, given by the usual \(\sqrt{\Delta x^2+\Delta y^2+\Delta z^2}\), whatever abomination of a number it might become:

\(\sqrt{(-\frac{806}{94}+8)^2+(-\frac{215}{94}-9)^2+ (-\frac{251}{94}-8)^2}\)

At this point is a simple exercise in number crunching which I refuse to entertain more - but please double check all calculation above in case I didn't notice something.

Answer:

\( x+y = 30\)   (1)

\( 1.95x+ 2.85y = 78.30\)   (2)

From equation (1) we can solve for x and we got:

\( x = 30-y\) (3)

Replacing (3) into (2) we got:

\( 1.95(30-y) +2.85 y = 78.30\)

And solving for y we got:

\( 58.5 -1.95 y +2.85 y = 78.30\)

\( 0.9 y = 19.8\)

\( y = 22\)

And then solving for x we got:

\( x = 30-22 = 8\)

So then we have 8 donuts and 22 cupcakes

Step-by-step explanation:

Let x the number of donuts and y the number of cupcakes, from the info given we can set up the following equations:

\( x+y = 30\)   (1)

\( 1.95x+ 2.85y = 78.30\)   (2)

From equation (1) we can solve for x and we got:

\( x = 30-y\) (3)

Replacing (3) into (2) we got:

\( 1.95(30-y) +2.85 y = 78.30\)

And solving for y we got:

\( 58.5 -1.95 y +2.85 y = 78.30\)

\( 0.9 y = 19.8\)

\( y = 22\)

And then solving for x we got:

\( x = 30-22 = 8\)

So then we have 8 donuts and 22 cupcakes

There is no whole number by which you can multiply or divide 16087 to make it a perfect square.

To determine by which number you should multiply or divide 16087 to make it a perfect square, we can analyze its prime factorization. The prime factorization of 16087 is 13 × 1237.

In order to make 16087 a perfect square, we need each prime factor to have an even exponent. However, when we examine the prime factors of 16087, we find that both 13 and 1237 have an exponent of 1.

To make the exponents even, we need to multiply or divide 16087 by additional prime factors and their respective exponents. However, since 16087 is a product of two prime numbers (13 and 1237), we cannot introduce any additional prime factors to make the exponents even.

A perfect square is a number that can be expressed as the product of two equal factors. In the case of 16087, it cannot be transformed into a perfect square by multiplying or dividing by any whole number. The prime factors 13 and 1237 remain with an exponent of 1 each, indicating that there is no integer that can be applied to make them equal and convert 16087 into a perfect square.

Therefore, there is no whole number by which you can multiply or divide 16087 to make it a perfect square.

The approximation for each of the given function and interval below is 1.12

The term function refers the special relationship where each input has a single output.

Here we have given that (a) R5, f(x) = x2 + x on the interval [−1,1]

And we need to find the the approximation for each of the given function and interval

Here we want to to calculate the right-endpoint approximation (the right Riemann sum) for the function:

=> f(x) = x² + x

For the interval [-1, 1] using five equal rectangles.

Let us find the width of each rectangle:

=> Δx = (1 - (-1))/5 = 2/5

Now, we have to list the x-coordinates starting with -1 and ending with 1 with increments of 2/5:

=> -1, -3/5, -1/5, 1/5, 3/5, 1.

Here we are find the right-hand approximation, we use the five coordinates on the right.

Then we have to evaluate the function for each value. This is shown in the table below.

And then each area of each rectangle is its area (the y-value) times its width, which is a constant 2/5.

Therefore, the approximation for the area under the curve of the function f(x) over the interval [-1, 1] using five equal rectangles is:

=> R₅ = 2/5 [-0.24  - 0.16 + 0.24 + 0.96 + 2] = 1.12
