Answers

Inside Out is a film about an 11 year old girl named Riley who moves across the country from Minnesota to San Francisco with her parents. Riley experiences a transformation in her mind and in who she is as a person as she tries to adjust to her new life in San Francisco and to the difficult process of growing up. The viewer follows Riley’s five emotions, Joy, Sadness, Anger, Fear, and Disgust, on a journey in her mind to help her through her transition to adolescence, and to assist her in making what they think are the right decisions. 

Final answer:

Inside Out is an animated movie detailing the emotional journey of an 11-year-old girl named Riley who moves to San Francisco. The film personifies Riley's core emotions: Joy, Sadness, Anger, Fear, and Disgust, outlining how they shape her actions and memories. The movie communicates a crucial message about the importance of all emotions, including sadness.

Explanation:

Inside Out is a movie presented by Pixar Animation Studios and released by Walt Disney Pictures. It showcases the story of an 11-year-old girl named Riley who moves from her hometown in Minnesota to San Francisco due to her father's new job. But this story is not a typical animation, as it transcends the usual plot setup. The unique aspect of this film is that it personifies Riley's five core emotions: Joy, Sadness, Anger, Fear, and Disgust, who live inside her mind and guide her actions and memories.

At the start of the movie, Riley's actions are primarily dictated by Joy, but the move to San Francisco triggers a series of events leading to Joy and Sadness getting lost in the depths of Riley's mind, leaving Anger, Fear, and Disgust in control. Throughout their journey to return to the headquarters, Joy and Sadness traverse various parts of Riley's mind, including Long-Term Memory, Imagination Land, and even the Subconscious, all the while Riley struggles with her new life.

In the end, the movie beautifully illustrates that all emotions are vital for a healthy mind - highlighting that sadness is as essential as joy. This plot overview simplifies a deep and complex movie, conveying a profound message about understanding and managing emotions.

how do you find the measure of each angle of m<8=115

Answers

You would do 180 - 115 and that gives you the < for 7

Answer:

1. 65 deg

2. 115 deg

3. 115 deg

Step-by-step explanation:

1.

Angles 7 and 8 are supplementary. Their measures add to 180 deg.

m<7 + m<8 = 180

m<7 + 115 = 180

m<7 = 180 - 115

m<7 = 65

2.

Since lines p and q are parallel lines cut by a transversal, corresponding angles 6 and 8 are congruent.

m<6 = m<8

m<6 = 115

3.

Angles 1 and 6 are vertical angles, so they are congruent.

m<1 = m<6

m<1 = 115

Find u*v, if u=13j and v=i+3j

Answers

Answer:

u * v = 39 ⇒ 2nd answer

Step-by-step explanation:

* Lets explain how to solve the problem

- u and v are two vectors

- u * v means the scalar product of the two vectors

- The scalar product is a way of multiplying vectors

- The result of a scalar product is always a number not a vector

- Ex: If u = ai + bj ⇒ <a , b> and v = ci + dj ⇒ <c , d>  then the scalar

 product of them is ac + bd where ac + bd is a number

* Lets solve the problem

∵ Vector u = 13j ⇒ <0 , 13>

∵ Vector v = i + 3j ⇒ <1 , 3>

- Lets find the scalar product

∴ u * v = (0)(1) + (13)(3)

∴ u * v = 0 + 39

u * v = 39

If g(x) = 3(x − 2), find the value of x if g(x) = 6.

Answers

Answer:

x=4

Step-by-step explanation:

From the statement we know that g(x)=3(x-2) and g(x)=6. Then we know that:

6=3(x-2)

Solving for "x":

6=3x-6

12=3x

x=12/3

x=4

Then, the solution is x=4.

For this case we have a function of the form [tex]y = g (x)[/tex]

Where:

[tex]g (x) = 3 (x-2)[/tex]

We want to find the value of "x" if the function is 6, that is, if y = 6

So, we have:

[tex]3 (x-2) = 6\\3x-6 = 6[/tex]

We clear "x":

[tex]3x = 6 + 6\\3x = 12\\x = \frac {12} {3}\\x = 4[/tex]

So, if the function has a value of 6, then [tex]x = 4[/tex]

Answers

Answer:

D. g(x) = -x^2 - 4

The required function g(x) = -x²- 4. Option D is correct.

f(x) = x², g(x) to be determine with help of graph.

What is function?

Function is defined as y = f(x). For every x their is certain value of y.

Here, from the graph g(x) is reflection of f(x) at y = -4.
So g(x) = -f(x) - 4
negative sign for reflection.
g(x) = -x²-4

The ordered pair is the point [tex](2b,2b+7)[/tex]

Step-by-step explanation:

we have

For [tex]x=2b[/tex]

Substitute the value of x in the function

so

[tex]f(2b)=2b+7[/tex]

therefore

The ordered pair is the point [tex](2b,2b+7)[/tex]

Answer:

(2b, 2b+7)

Step-by-step explanation:

Since the value of x is 2b, we just have to insert that value into the function in order to solve the ordered pair, we have the first part of the ordered pair, which is (2b), now we just insert the value of x into the function:

[tex]f(x)=x+7\\f(x)=2b+7[/tex]

Now we know that the value of y would be 2b +7, and the ordered pair will be (2b,2b+7)

Classwork 12.1 surface area

Answers

Answer:

6) LA = 90 units² and SA = 202 units²

7) LA = 377 units² and SA = 477.5 units²

8) LA = 208 units² and SA = 232 units²

9) LA = 455 units² and SA = 591 units²

Step-by-step explanation:

* Lets revise the rules of lateral area and surface area

- Lateral area of the solid = perimeter of its base × its height

- Surface area = lateral area + 2 × area of its base

* Now lets solve the problems

6) The solid is a rectangular prism

- Its base is a rectangle with dimensions 8 units and 7 units

- Its height is 3 units

∵ Perimeter of the rectangle = 2(L + W)

∴ Perimeter of the base = 2(8 + 7) = 2(15) = 30 units

∴ LA = 30 × 3 = 90 units²

∵ Area of the rectangle = L × W

∴ Area of the base = 8 × 7 = 56 units²

∴ SA = 90 + 2 × 56 = 90 + 112 = 202 units²

7) The solid is a cylinder

- Its base is a circle with diameter 8 units

∴ Its radius = 8 ÷ 2 = 4 units

- Its height is 15 units

∵ The perimeter of the circle is 2πr

∴ The perimeter of the base = 2π(4) = 8π

∴ LA = 8π(15) = 120π = 376.99 ≅ 377 units²

∵ The area of the circle = πr²

∴ The area of the base = π(4)² = 16π

∴ SA = 120π + 2 × 16π = 120π + 32π = 152π = 477.5 units²

6) The solid is a triangular prism

- Its base is a triangle with sides 5 , 5 , 6 units and height 4 units

- Its height is 13 units

∵ Perimeter of the triangle is the sum of the 3 sides

∴ Perimeter of the base = 5 + 5 + 6 = 16 units

∴ LA = 16 × 13 = 208 units²

∵ Area of the triangle = 1/2 × base × height

∴ Area of the base = 1/2 × 6 × 4 = 12 units²

∴ SA = 208 + 2 × 12 = 208 + 24 = 232 units²

9) The solid is a prism

- Its base is an isosceles trapezium with parallel bases 7 units and 10

 units, 2 non-parallel bases 9 units and height 8 units

- Its height is 13 units

∵ Perimeter of the trapezium is the sum of its sides

∴ Perimeter of the base = 7 + 10 + 9 + 9 = 35 units

∴ LA = 35 × 13 = 455 units²

∵ Area of the trapezium = 1/2(b1 + b2) × h

∴ Area of the base = 1/2(7 + 10) × 8 = 68 units²

∴ SA = 455 + 2 × 68 = 455 + 136 = 591 units²
