1/25=0.04
9/25=9*0.04=0.36
The radius of a circle is half the length of the diameter so
radius=1.5m
Yes... indeed it is 1/8 because
125/1000 In simplest form is 1/8
Differentiate:
-5×2(xe^x^2)y-5e^x^2dy/dx=1
-5e^x^2(2xy+y´)=1
When x=-5, y=0:
-5e²⁵y´=1, so y´(-5)=-eˉ²⁵/5
Answer:
a)

b) 0.09
Step-by-step explanation:
We are given the following in the question:

where B(t) gives the brightness of the star at time t, where t is measured in days.
a) rate of change of the brightness after t days.

b) rate of increase after one day.
We put t = 1

The rate of increase after 1 day is 0.09
