Answer:
1
Step-by-step explanation:
The slope of the perpendicular is the negative inverse of the slope of the line.
m = -1 / (-⅓)
m = 3
The slope between the two points is 3, so:
3 = (15 − 6) / (4 − n)
3 (4 − n) = 9
4 − n = 3
n = 1
To solve this, first we'll find the area of the rectangle A,
Area=length × width
?=24m×20m
480m=24m×20m
480m squared=area of the rectangle A
now we'll find the width of rectangle B,
"the width of rectangle B is 12 meters less than the width of rectangle A",
20m-12m= 8m
8m=width of rectangle B
finally we'll find the length of rectangle B,
area of the rectangle B= 480msquared
width= 8m
length=? (to find this divide the area by the width)
480÷8=60m
length of the rectangle B=60m

Answer:

Step-by-step explanation:
We are given that
By ohm's law

R=389 ohm
I=0.03 A


We have to find rate of change of current I means 
Differentiate the equation w.r.t t

Substitute the values then we get





Hence, the current I is changing at the rate=-0.00016A/s
Answer:
T(t) = 5(3)(t)
Step-by-step explanation:
There are 5 cells initially.
And it triple every hour.
So
T0 =5
T(t) = T0(3t)
Each cell has it's multipling factor because it's Will be multipling by 3 every hour
T(t) = 5(3)(t)
