1. how might mathematics play a role in making movies? name some movies where math might have been used.

Answer with Explanation:

Mathematics plays a vital role in human lives. It is also used not only in schools, but also when it comes to making films. An example of these films are "Pixar" animated films such as "Toy Story" and "Incredibles 2."

For example, the movement of one character from the left to the right (sliding movement), when it comes to computers is being done with the help of a mathematical concept called "Coordinate geometry." This allows to bridge the gap between what designers want with their characters and its movement. So, in order to do this, the mathematical translation used is "addition" because the x coordinate started with 1 as its value and this ended with the value of 5 when the picture slid to the right. When it comes to making characters larger in an anime, we have to consider the concept of "multiplication." On the other hand, if objects are to be rotated, we have to consider the concept of "Trigonometry."

This is just one way Mathematics play a role in making movies.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
