Answer:
It will take 47 hours
Step-by-step explanation:
We can have the exponential function as follows;
P = I( 1 + r)^n
if the initial value was x , the final will be 2x
The change rate is 1.5% , which is r, this is same as;
1.5/100 = 0.015
So what we want to calculate is the n attached
This will be;
2x = x ( 1 + 0.015)^n
2 = 1.015^n
ln 2 = n ln 1.015
n = ln 2/ln 1.015
n = 46.55
This is approximately 47 hours
Step-by-step explanation:
I think Rewrite the equation as
z
=
20
x
−
3
y
.
z
=
20
x
−
3
y
The first one includes both
Let the second side be equal to x
Then the first side is x-5
The third side will be x-5-2 = x-7
Therefore you add all the following sides and equate it to 42 yards. Ie x+x+5+x-7 = 42
3x=44
X= 44/3
Therefore the second sides length is 44/3
The first sides length is 44/3 -5 = 29/3
The third side is 44/3 -7 = 23/3
