e = k.m
360 = k.60
k = 360/60 = 36/6 = 6
108 = 6.m
108/6 = m = 18
Answer:
f(1)=16
Step-by-step explanation:
f(t)=-16t+32t
f(1)=-16(1)+32(1)
f(1)=-16+32
f(1)=16
10. (5,8)(-3,7)
slope = (7 - 8) / (-3 - 5) = -1 / -8 = 1/8
11. (5,-2)(3,-2)...since both y values are the same, this line is a horizontal line with a 0 slope.
12. (-4,7)(8,-1)
slope = (-1 - 7) / (8 - (-4) = -8 / (8 + 4) = -8/12 = - 2/3
13. (6,-3)(6,4)....since both x values are the same, this line is a vertical line with a slope that is undefined
14. -2/5
Answer:
the rate should be 6ml/hr
Step-by-step explanation:
if 100 ml of solution have 50 units each ml has 0.5 units, (50/100)
so in order to get 3 units in one hour the equation would be
number of units = units per mililiter * number of mililiters in an hour
3 = 0.5 * x
x= 3 / 0.5 = 6ml/hr
