Can u guys PLEASE answer question a and f

a) 0.61

b) 1.06

Step-by-step explanation:

a) v = u + at

12 = 6 + 9.8t

9.8t = 6

t = 6 ÷ 9.8 = 0.612244898

t = 0.61

f) w = ¾(gk)

7.4 = ¾ (9.31k)

9.31k = 7.4 × 4/3

9.31k = 9.86666667

k = 9.8666667 ÷ 9.31

k = 1.059792338

k = 1.06

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

i belive those are the ones that are under 90 degreese.
