Need help with these questions

1. 12

2. -23

3. 15

Step-by-step explanation:

We are given a and b, so we just plug these in.

a = 1/4 or 0.25

b = 6

-8(0.25)(6) = 12

16a^2 - 4b

16(.25)^2 - 4(6) = -23

(5b)/(32a^2)

5(6)/32(.25)^2 = 15

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
