With two dice, you can get sums of between 2 and 12,
Answer:
JL = 62 (units)
Step-by-step explanation:
OK, Here we can use the part whole postulates theorem to assist us:
JL consists of parts JK + KL such that, through substitution,
5x + 2 = 27 + ( 3x - 1 )
Here we can solve for x to determine 5x + 2, and thus the value of JL:
5x + 2 = 27 + 3x - 1
2x + 2 = 27 - 1
2x + 2 = 26
2x = 24
x = 12
Substitute the value of x for 5x + 2, to get JL:
JL = 5 (12) + 2
JL = 60 + 2
JL = 62 (units)
See picture for math work and answer.
Suppose the number of bacteria are increasing exponentially, We can model the number of bacteria at a given time t, using the formula:
f(t)=ae(tk)
where, k=constant of proportionally and a=initial number;
thus;
f(t)=2000e(0.005t)
Therefore the population after 12 hours will be:
f(12)=2000e^(0.005*12)
f(12)=2,123.67=2,123 bacteria
Answer:
y = -3x
Step-by-step explanation:
(a) Slope
y = mx + b
Choose points (-3, 9) and (3, -9)
m = (-9 - 9)/(3 – (-3))
m = -18/(3 + 3)
m = -18/6
m = -3
=====
(b) y-intercept
y = mx +b
Choose point (0,0).
0 = 0 + b
b = 0
=====
(c) Equation of line
y = mx + b
y = -3x
