Order number from least to greates
9/5 -2.5 -1.1 -4/5 0.8

Step-by-step explanation:

Start by writing these five numbers in just one format (improper fractions with denominator 10):

9/5 = 18/10, and

-2.5 = -25/10, and

-1.1 = -11/10, and

-4/5 = -8/10, and, finally

0.8 = 8/10

The smallest of these (the least) is -25/10, and

the largest is 18/10.

Arranged in ascending order, we have:

-25/10, -11/10, -8/10, 8/10, 18/10, or

-2.5, -1.1, -4/5, 0.8, 9/5

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
