Answer: [tex]A = 108.80\ units^2[/tex]

Step-by-step explanation:

The surface  area of right cone is calculated by the following formula

[tex]A = \pi r *\sqrt{r^2 +h^2}+\pi r^2[/tex]

Where r is the radius of the cone and h is the height

In this case we know that the diameter d of the base is:

[tex]d=2r[/tex]

So the radius is:

[tex]r=\frac{d}{2}\\\\r=\frac{6}{2}\\\\r=3\ units[/tex]

and

[tex]h=8\ units[/tex]

So the area is:

[tex]A = \pi*3 *\sqrt{3^2 +8^2}+\pi(3)^2[/tex]

[tex]A = 108.80\ units^2[/tex]

Answer:

[tex]SA=108.8 units^2[/tex]

Step-by-step explanation:

The surface area of a right cone is given by

[tex]S.A=\pi r^2+\pi rl[/tex]

The relation between the slant height l, the radius r, and the height h, is

[tex]l^2=r^2+h^2[/tex]

[tex]l^2=3^2+8^2[/tex]

[tex]l^2=9+64[/tex]

[tex]l^2=73[/tex]

[tex]l=\sqrt{73}[/tex]

[tex]S.A=\pi \times 3^2+\pi \times3\times\sqrt{73}[/tex]

[tex]S.A=\pi \times 3^2+\pi \times3\times\sqrt{73}[/tex]

ANSWER

The correct answer is A

EXPLANATION

The given polynomial is

[tex]p(x) = {x}^{5} + 32[/tex]

According to the remainder theorem, if p(x) is divided by x+2 the remainder is p(-2).

If the remainder is zero then x+2 is a factor of f(x).

We plug in x=-2 into the function to obtain;

[tex]p( - 2) = { (- 2)}^{5} + 32[/tex]

[tex]p( - 2) = - 32 + 32[/tex]

[tex]p( - 2) = 0[/tex]

Since the remainder is zero, x+2 is a factor.

The correct answer is A

Answer: 432 units²

Step-by-step explanation:

The figure is composed by two trapezoids.

The formula for calculate the area of a trapezoid is:

[tex]A=\frac{h}{2}(B+b)[/tex]

Where "B" is the larger base, "b" is the smaller base and "h" is the height.

Let be [tex]A_f[/tex] the area of the figure, [tex]A_1[/tex] the area of the trapezoid on the left and [tex]A_2[/tex] the area of the trapezoid of the right. Then the area of the figure will be:

 [tex]A_f=A_1+A_2[/tex]

[tex]A_f=\frac{h_1}{2}(B_1+b_1)+\frac{h_2}{2}(B_2+b_2)[/tex]

Substituting values, you get:

[tex]A_f=\frac{16units}{2}(25units+4units)+\frac{10units}{2}(25units+15units)=432units^2[/tex]

Answer:

Area of given figure = 432 unit ²

Step-by-step explanation:

Points to remember

Area of trapezoid = h(a + b)/2

Where h - height  and a and b  are two parallel sides

To find the area of given figure

It is given two trapezoid

Area of 1st trapezoid

h = 16, a = 25 and b = 4

Area = h(a+ b)/2

 = 16(25 + 4)/2

 = 232 units ²

Area of 2nd trapezoid

h = 10, a = 25 and b = 15

Area = h(a+ b)/2

 = 10(25 + 15)/2

 = 200 units ²

Total area = 232 + 200 = 432 units²

That is very true.

In mathematics, an inverse operation is an operation that undoes what was done by the previous operation. The four main mathematical operations are addition, subtraction, multiplication, division. The inverse of addition is subtraction and vice versa. The inverse of multiplication is division and vice versa.

Addition and subtraction are indeed inverse operations. They are algebraic operations that do the opposite of one another and can thus 'undo' each other's effects.

The statement that Addition and subtraction are inverse operations is indeed true. In mathematics, an inverse operation is an operation that undoes what was done by the previous operation. In the case of addition and subtraction, they do exactly that. For instance, if you were to add 3 and 4 to get 7, you can undo this operation by subtracting 3 or 4 from 7 which will give back the other original number. Hence, addition and subtraction are deemed as inverse operations.

I believe the answer is B

Final answer:

The slope of the line containing the points (4,8) and (9,8) is 0, indicating that it is a horizontal line. The correct answer is B. Slope = 0; horizontal line.

Explanation:

The slope of a line is calculated by taking the difference in the y-values of two points on the line (rise) and dividing by the difference in the x-values (run). Using the points (4,8) and (9,8), we can calculate the slope as follows:

Slope (m) = rise / run = 0 / 5 = 0.

Since there is no change in the y-value as we move from one point to the other, the line is horizontal. Thus, the line has a slope of 0. The correct answer to the student's question is B. Slope = 0; horizontal line.

Answer:

A)13.3

Step-by-step explanation:

20² + y² = 24²

400 + y² = 576

y²  = 176

y=13.3

By Pythagoras theorem, in the given right triangle, the missing length to the nearest tenth is Option(A) 13.3 ft.

According to Pythagoras theorem, the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.

Mathematically,

(Hypotenuse)² = (Base)² + (Height)² .

For the given triangle, length of hypotenuse is 24ft., height is 20ft and base is y ft.

Using Pythagoras theorem,

⇒ (24)² = y² + (20)²

⇒ y² = 24² - 20²

⇒ y² = 176

∴ y = √176 = 13.2665 ≈ 13.3 ft.

Thus, by Pythagoras theorem, in the given right triangle, the missing length to the nearest tenth is Option(A) 13.3 ft.

Jenny's Stats

t = m - 2

d = 60 miles

Step-by-step explanation:

Given a polynomial with zeros x = a, x = b, x = c

Then the factors are (x - a), (x - b) and (x - c)

and the polynomial is the product of the factors

f(x) = k(x - a)(x - b)(x - c) ← k is a multiplier

here the zeros are x = - 3, x = 0, x = 4, thus the factors are

(x - (- 3)), (x - 0) and (x - 4), that is

(x + 3), x and (x - 4)

let k = 1, then

f(x) = x(x + 3)(x - 4) → 3

Step-by-step explanation:

The volume of Zara's sandwich formed as a rectangular prism, is 421.2 cm³, calculated by multiplying the sandwich's length, width, and height. The surface area is 561.6 cm² which is calculated by adding the areas of each face of the prism. When the sandwich is cut and stacked, the volume remains the same, but the surface area increases.

A. To find the volume of a prism (such as Zara's sandwich), we multiply the length by the width by the height. So, for Zara's sandwich, we would calculate the volume as follows (in cubic centimeters): 13cm × 10.8cm × 3cm = 421.2 cm³.

B. The surface area of a rectangular prism is calculated by 2lw + 2lh + 2wh (where l is the length, w is the width, and h is the height. Plugging in the dimensions Zara measured, we find the surface area to be: 2(13cm × 10.8cm) + 2(13cm × 3cm) + 2(10.8cm × 3cm) = 561.6 cm².

C. When Zara cuts her sandwich in half and stacks one half on top of the other, she is effectively doubling the height while keeping the length and width the same. However, since neither the volume nor surface area formulas have a square or cube factor in the height, the volume will be the same. As for the surface area, because the height is now equivalent to two sandwich halves, and the 'length' is not shared between the two halves, the surface area increases. So, Zara's conclusions are incorrect. The volume stays the same, while the surface area increases.

a. The volume of Zara's sandwich is 421.2 cm³.

b. The surface area of Zara's sandwich is 561.6 cm².

c. Zara's conclusions are incorrect. The volume stays the same, while the surface area increases.

A. To calculate the volume of a prism (such as Zara's sandwich), multiply its length by breadth by height. So, for Zara's sandwich, the volume would be calculated as follows (in cubic centimeters): 13cm 10.8cm 3cm = 421.2 cm³.

B. A rectangular prism's surface area is computed as 2lw + 2lh + 2wh (where l is the length, w is the width, and h is the height). Using Zara's measurements, we calculate the surface area to be: 2(13cm 10.8cm) + 2(13cm 3cm) + 2(10.8cm 3cm) = 561.6 cm².

C. By cutting her sandwich in half and stacking one half on top of the other, Zara essentially doubles the height while maintaining the length and width. The volume, however, will be the same because neither the volume nor surface area formulae include a square or cube element in the height. The surface area grows since the height is now equivalent to two sandwich half and the 'length' is not split between the two halves. Zara's conclusions are thus wrong. The volume remains constant while the surface area grows.

For this case we must solve the following quadratic equation:

[tex]-3x ^ 2 + 1467x-86940 = 0[/tex]

If we divide both sides of the equation by 3 we have:

[tex]-x ^ 2 + 489-28980 = 0[/tex]

The solutions will come from:

[tex]x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}[/tex]

Where:

[tex]a = -1\\b = 489\\c = -28980[/tex]

Substituting:

[tex]x = \frac {-489 \pm \sqrt {(489) ^ 2-4 (-1) (- 28980)}} {2 (-1)}\\x = \frac {-489 \pm \sqrt {239121-115920}} {- 2}\\x = \frac {-489 \pm \sqrt {123201}} {- 2}\\x = \frac {-489 \pm351} {- 2}[/tex]

The roots are:

[tex]x_ {1} = \frac {-489 + 351} {- 2} = \frac {-138} {- 2} = 69\\x_ {2} = \frac {-489-351} {- 2} = \frac {-840} {- 2} = 420[/tex]

2. We need to find out the multiple of 8 closest and lower than 500.

....480, 488, 496, 504, 512, 520......It's 496

3. Now, we use 104 and 496, this way:

(496 - 104)/8 + 1 =

392/8 + 1 =

49 + 1 = 50

There are 50 multiples of 8 between 100 and 500

Answer:

50

Step-by-step explanation:

The smallest multiple of 8 in this range is 13 ∙ 8 = 104, and the largest is 62 ∙ 8 = 496. The number of multiples of 8 in this range is the same as the number of numbers in the list

13, 14, 15, ...,60, 61, 62.

To count these, we subtract 12 from each, obtaining the new list

1, 2, 3, ..., 48, 49, 50,

which clearly contains 50 integers. There is one number in the original list for each number in the revised list, so the original list has 50 numbers in it, and there are 50 multiples of 8 between 100 and 500.

Answer:

a = 4, b = 3, and c = -3

Step-by-step explanation:

A quadratic equation of a variable is an equation that has the general form of:

[tex]ax^{2}+bx+c=0[/tex], [tex]a\neq 0[/tex]

Where x is the variable, and a, b and c constants; a is the quadratic coefficient (other than 0), b the linear coefficient and c is the independent term. This polynomial can be interpreted by means of the graph of a quadratic function, that is, by a parabola. This graphical representation is useful, because the abscissas of the intersections or point of tangency of this graph, in the case of existing, with the X axis are the real roots of the equation. If the parabola does not cut the X axis the roots are complex numbers, they correspond to a negative discriminant.

So, the coefficients are  a = 4, b = 3, and c = -3
