25x^2+1=5 quadratic

1 answer:

3 0

25x² + 1 = 5

25x² + 1 - 5 = 0

25x² - 4 = 0 By difference of two squares

(5x)² - (2)² = 0

(5x - 2)(5x + 2) = 0

5x - 2 = 0 or 5x + 2 = 0

5x = 0 + 2 5x = 0 - 2

5x = 2 5x = -2

x = 2/5 x = -2/5

x = 0.4 x = -0.4

x = + 0.4 or -0.4

A plane is defined as what type of figure? A. 1-dimensional B. 2-dimensional C. 3-dimensional D. A plane has no dimensions.

Dmitry_Shevchenko [17]

A plane is defined as a figure that has B, two dimensions.

This question is about definitions, and the definition of a plane is that it is a flat surface with two dimensions. But, since everything in our world is 3 dimensions (everything, even if it looks small, has some kind of depth), there are no planes in our world. A plane also extends infinitely far, and can be named by 3 points on it.

Carlos performed a transformation on trapezoid EFGH to create E′F′G′H′, as shown in the figure below:

Nataliya [291]

Answer:

90° clockwise rotation or 270° anticlockwise rotation

Step-by-step explanation:

(x,y)=(y,-x)

E(-6,-4)=E'(-4,6)

F(-4,-4)=F'(-4,4)

G(-2,-6)=G'(-6,2)

H(-7,-7)=H'(-7,7)

Therefore, E prime is (-4,6), F prime is (-4,4), G prime is (-6,2) and H prime is (-7,7).
