Milli(m) = 1/10^3 = 0.001
kilo(k) = 10^3 = 1000
8.41 * g/ml
= 8.41 g/mL / 1000 mL
= 0.00841 g/L
g = 10^3 * (1/10^3) * g
= (1/10^3) * kg
0.00841 g/L / 1000 g
= 0.00000841 kg/L
Usually bacteria expansion is modeled with exponential function.
Absolute value is not the correct answer since it models linear growth.
Logarithmic is not the correct answer since it has an asymptote in the direction of the x axis.
I will answer to this question "Polynomial" since it is likely to represent bacteria growth.
B and c would be answered
Answer:
Solution given:
AD=1.8
AC=3.0
we have
∆ADC is a right angled triangle
Cos A=b/h
<A=cos-¹ (1.8/3)
<A=53.13°
again
∆ABC is a right angled triangle
Tan A=p/b=BC/AC
Tan 53.13×3=BC
BC=4
NOW
Area of triangle =½(AC*BC)=½(4×3)=6 <u>square </u><u>units</u><u> </u><u>is</u><u> </u><u>a</u><u> </u><u>required</u><u> </u><u>area</u><u>.</u>
