Answer:
4.229
Step-by-step explanation:
75 = 4(2)^x
75/4 = 2^x
Apply ln both sides
ln(75/4) = ln(2^x)
ln(75/4) = x ln(2)
x = ln(75/4) ÷ ln(2)
x = 4.22881869
Solution:
To find the equation of line passing through points A (1, 3) and B (3, 7).
we know that, to derive the equation of a line we first need to calculate the slope of the line. Slope m of a line at points and is given by - .
Slope of the line at point A(1,3) and B(3,7)
.

Equation of a line using a point and a slope ,
The equation of line passing through points A (1, 3) and B (3, 7) :
Answer:
48,58
Step-by-step explanation:
Let The speed of the west bound train be x
Let the east bound train be x+10
The speeds can be calculated as follows
2(2x+10)= 232
4x + 40= 232
4x= 232-40
4x= 192
x= 192/4
= 48
Hence the speedof the west bound train is 48
The speed of the east bound train is 48+10
= 58
