A company is designing a new cylindrical water bottle. The volume of the bottle will be 121 cmcubed. The height of the water bottle is 7.6 cm. What is the radius of the water​ bottle? Use 3.14 for pi.

Answers

Answer:

The radius of the water bottle is 2.25 cm

Step-by-step explanation:

The water bottle is said to be cylindrical, so its volume can be expressed as the volume of a cylinder.

Volume of a cylinder V = πr^2 h

Where;

h = height

r = radius

Making the radius the subject of formula;

r^2 = V/πh

r = √(V/πh)

Given:

Volume V = 121 cm^3

height h = 7.6 cm

π = 3.14

Substituting the given values;

r = √(121/(3.14×7.6))

r = 2.25 cm

The radius of the water bottle is 2.25 cm

An ice cream shop sells cones in two sizes.

height of 5 inches. Find the difference in
volume of the cones to the nearest
tenth.
SOLUTION:
HOW DO YOU KNOW?

Y’all I need help ASAP!! All work is due at 12am and I can’t fail.

Answers

Answer:  The difference is 6.5 inches.

Step-by-step explanation:

The volume of a cone uses the formula V= nr^2 h/3

So the large cone's volume is  V= 3.14 * 1.5^2 *5/ 3

                                              v= 11.775

The volume of the small cone is V= 3.14 * 1^2* 5/3

                                                      V=5.23

Now find the difference.   11.775 - 5.23= 6.54

Round to the nearest tenth is  6.5

This composite figure is made of two identical pyramids attached at their bases. Each pyramid has a height of 2 units.Which expression represents the volume, in cubic units, of the composite figure?

Answers

This question is incomplete.

Complete question

This composite figure is made of two identical pyramids attached at their bases. Each pyramid has a height of 2 units.

2 identical pyramids with rectangular bases are connected at their base. The height of the pyramid is 2. The lengths of the sides of the rectangle are 5 and 0.25 units.

Which expression represents the volume, in cubic units, of the composite figure?

Answer:

2(1/3(5)(0.25)(2))

Step-by-step explanation:

The volume of a rectangular pyramid is given as

1/3 × (Area of the base rectangle ) × Height

Area of the base rectangle = Length × Width

We are told in the question that:

The lengths of the sides of the rectangle are 5 and 0.25 units.

Area of the base rectangle = 5 units × 0.25 units

The height of the pyramid = 2 units

Therefore, the volume of the rectangular pyramid = 1/3× (5×0.25) × 2

We are also told in the question that this composite figure is made of two identical pyramids attached at their bases.

Therefore, expression that represents the volume, in cubic units, of the composite figure is given as:

2(1/3× (5×0.25) × 2) = 2(1/3(5)(0.25)(2))

Uma urna contém 10 bolas identificadas pelas letras A, B, ..., J. Uma bola é extraída ao acaso da urna e sua letra é observada. (Deixe explícito o espaço amostral e todos os eventos). Qual é a probabilidade de uma letra da bola sorteada ser: a) Vogal b) Consoante

Answers

Answer:

a) Probability that a letter of the drawn ball is vowel = (3/10) = 0.30

b) Probability that a letter of the drawn ball is consonant = (7/10) = 0.70

a) Probabilidade de uma letra da bola sacada ser vogal = (3/10) = 0.30

b) Probabilidade de uma letra da bola sacada ser consoante = (7/10) = 0,70

Step-by-step explanation:

English Translation

A ballot box contains 10 balls identified by the letters A, B, ..., J. A ball is drawn at random from the ballot box and its letter is observed. (Make the sample space and all events explicit). What is the probability that a letter of the drawn ball is: a) Vowel b) Consonant

Solution

The 10 balls are identified by A, B, C, D, E, F, G, H, I and J

Note that the probability of an event is given as the number of elements in that event divided by the number of elements in the sample space.

a) Probability of drawing a ball that has a vowel letter = P(v)

P(v) = n(v) ÷ n(S)

n(v) = Number of balls with vowel letters = 3 (that is, A, E and I)

n(S) = Total number of balls = 10

P(v) = (3/10) = 0.30

b) Probability of drawing a ball that has a consonant letter = P(c)

P(c) = n(c) ÷ n(S)

n(c) = Number of balls with consonant letters = 7 (that is, B, C, D, F, G, H and J)

n(S) = Total number of balls = 10

P(c) = (7/10) = 0.70

In Portugese/Em português

As 10 bolas são identificadas por A, B, C, D, E, F, G, H, I e J.

Observe que a probabilidade de um evento é fornecida como o número de elementos nesse evento dividido pelo número de elementos no espaço de amostra.

a) Probabilidade de desenhar uma bola com uma letra de vogal = P (v)

P (v) = n (v) ÷ n (S)

n (v) = Número de bolas com letras de vogal = 3 (ou seja, A, E e I)

n (S) = Número total de bolas = 10

P (v) = (3/10) = 0,30

b) Probabilidade de desenhar uma bola com uma letra consoante = P (c)

P (c) = n (c) ÷ n (S)

n (c) = Número de bolas com letras consoantes = 7 (ou seja, B, C, D, F, G, H e J)

n (S) = Número total de bolas = 10

P (c) = (7/10) = 0,70

Which function does the graph represent? f(x) = (x + 3)(x + 7) f(x) = (x – 3)(x – 7) f(x) = 3(x – 3)(x – 7) f(x) = 11(x + 3)(x + 7)

Answers

This question is incomplete because it lacks the picture of the graph. Find attached to the answer, the picture of the graph.

Question:

Which function does the graph represent?

a) f(x) = (x + 3)(x + 7)

b) f(x) = (x – 3)(x – 7)

c) f(x) = 3(x – 3)(x – 7)

d)f(x) = 11(x + 3)(x + 7)

Answer:

c) f(x) = 3(x – 3)(x – 7)

Step-by-step explanation:

The function of a graph or the the graph of a function is when

f(x) = y

From the attached graph, after reading it,

They are three specific points on the x - axis, where x = 3 and x = 7, x = 8

So, where x = 3 on the x axis, y =

f(3) = 0

where x = 7 on the x axis, y =

f(7) = 0

So, where x = 8 on the x axis, y =

f(8) = 15

Looking at the options in the question,

a) f(x) = (x + 3)(x + 7)

f(x) = y

where x= 3

f(3) = (3+3)(3+7)

= 60

where x= 7

f(7) = (7+3)(7+7)

= 140

where x= 8

f(8) = (8+3)(8+7)

= 165

This option is wrong

b) f(x) = (x – 3)(x – 7)

f(x) = y

where x= 3

f(3) = (3-3)(3-7)

= 0

where x= 7

f(7) = (7-3)(7-7)

= 0

where x= 8

f(8) = (8-3)(8-7)

= 5

This option is wrong.

c) f(x) = 3(x – 3)(x – 7)

f(x) = y

where x= 3

f(3) = 3(3-3)(3-7)

= 0

where x= 7

f(7) =3(7-3)(7-7)

= 0

where x= 8

f(8) = 3(8-3)(8-7)

= 3(5)(1)

= 15

This option is correct

d)f(x) = 11(x + 3)(x + 7)

f(x) = y

where x= 3

f(3) = 11(3+3)(3+7)

= 660

where x= 7

f(7) = 11(7+3)(7+7)

= 1540

where x= 8

f(8) = 11(8+3)(8+7)

= 1815

Therefore, function the graph represents is Option c) f(x) = 3(x – 3)(x – 7)

Answer: The answer is C. f(x)= 3(x-3)(x-7)

PLEASE HELP !!! When 3x^2 - 5x + c is divided by x + k, the quotient is 3x + 1 and the remainder is 3. Find c and k.

Answers

Answer:

The values are k = -2 and c = 1

Step-by-step explanation:

Since it's a division of polynomials we can calculate "c" and "k" by using the inverse operation, which is the product. We need to multiply "x + k" with "3x + 1" and sum it with 3, that should be equal to "3x² - 5x + c". We have:

[tex]3x^2 - 5x + c = (x + k)*(3x + 1) + 3\\3x^2 - 5x + c = 3x^2 + x + 3kx + k + 3\\3x^2 - 5x + c = 3x^2 + (1 + 3k)x + (k+3)[/tex]

In order for two polynomials to be equal, every coefficient must be equal, therefore:

[tex]-5 = 1 + 3k\\1 + 3k = -5\\3k = -5 -1\\3k = -6\\k = -2[/tex]

[tex]c = k + 3\\c = -2 + 3\\c = 1[/tex]

[tex]d.\ x=-i, i, 3 \sqrt{5}\ or\ -3 \sqrt{5}[/tex]

Step-by-step explanation:

The given equation has a degree 4  (Highest power of [tex]x[/tex]):

[tex]x^4-44x^2-45=0[/tex] is the given equation which can be written as:

[tex](x^2)^2-44x^2-45=0 ...... (1)[/tex]

Let [tex]t=x^{2}[/tex] and putting it in equation (1):

[tex]t^2-44t-45=0 \\[/tex]

Solving the above quadratic equation in variable [tex]t[/tex]:

[tex]\Rightarrow t^2-45t+t-45=0 \\\Rightarrow t(t-45)+1(t-45)=0\\\Rightarrow (t+1)(t-45)=0\\\Rightarrow t =-1\ or\ 45[/tex]

We know that [tex]t=x^{2}[/tex]

So, [tex]x^{2} =-1\ or\ x^{2}= 45[/tex]

1. Solving [tex]x^{2} =-1[/tex]

[tex]\Rightarrow x = +\sqrt{-1}\ or\ -\sqrt{-1}\\\Rightarrow x = i\ or\ -i[/tex]

2. Solving [tex]x^{2} =45[/tex]

[tex]\Rightarrow x = +\sqrt{45}\ or\ -\sqrt{45}\\\Rightarrow x = 3\sqrt{5}\ or\ -3\sqrt{5}[/tex]

Hence, correct answer is:
