Answer:

9 + 3 x ( 2 ^2 - 1 ) x 4 = 45

Step-by-step explanation:

1: 2x2 - 1 = 3

2: 9 + 3 x 3 x 4 = 45

3: 9 + 9 x 4 = 45

To change the value of expression to 45 we need to put the parentheses in front 2 and after 1.

Don't forget the order of operation.

What is the mapping rule for a 45 degree rotation?

sleet_krkn [62]

Step-by-step explanation:

Imagine a line segment on a coordinate plane that rotates around the origin like a clock hand. If it travels 45° (or any positive degree angle), it will travel in a counterclockwise direction. If it rotates -45° degrees (or any negative degree angle), it will travel in a clockwise direction.

A triangle T is bounded (on three sides) by the lines x = 6, y = 0, and y = 3 2 x. A rectangle of width w is inscribed inside T.

Viktor [21]

Answer:

33.85 units^2

Step-by-step explanation:

you must first draw the triangle on the plane using the equations (see

attached file), you will have a right angle triangle with a height of 192 and a base of 6.

then you calculate the angle with the tangent function = 88.21

Then you use the small triangle to find the value of a (see attached file).

Finally, you propose an equation for X to find one of the sides of the triangle, once you have x squared it, and you already have the area,
