Vertical angles are opposite angles made by intersecting lines

a and b are not vertical angles no

Complementary angles - two angles that add to 90 degrees

b is 90 degrees by itself no

Supplementary angles - two angles that add to 180 ( would make a straight line)

a and b do not form a straight line they are not vertical angles - no

Let f be the function defined as follows.

Debora [2.8K]

Y = f(x) = 8x^2 - 2x + 3
a.) dy/dx = 16x - 2

b.) dy = (16x - 2)dx
dy = (16(2) - 2)(2 - 1.97) = 0.03(32 - 2) = 0.03 * 30 = 0.9
dy = 0.9

c.) (8(2)^2 - 2(2) + 3) - (8(1.97)^2 - 2(1.97) + 3) = 31 - 30.1072 = 0.8928
Δy = 0.8928

What is the rational number equivalent to 1.28? The 1.28 has a line above the 28

Svetach [21]

the line over the 28 means the 28 repeats forever.
1.282828.... and so on
let x be the rational number 1.28...
we can use this trick:
100*1.282828....= 128.282828...
(the decimal 28 part repeats) 100x = 128.28...
next: 100x - x = 128.282828... - 1.282828...
the .282828... part will be subtracted away
99x = 127
divide both sides by 99 to get
x= 127/99
