Answer:
Given that,
In right triangle ABC, C is the right angle.
sin A=0.4
To find cos B,
we get the triangle as,
we know that,
Hypotenuse of the triangle is AB
For the angle A, opposite side is CB
For the angle B, adjacent side is CB
From the definition of sine and cosine we get,

Also,

Comparing both we get,

It is given that sinA=0.4
Hence we get, cosB=0.4
Answer is: 0.4
Answer:
After 7 years the population will be 15268.
Step-by-step explanation:
Given a town has a population of 12000 and grows at 3.5% every year. we have to find the population after 7 years.
As the general growth formula is

where A = Amount after growth
P = Original amount
r = yearly growth rate
t = no. of years
here, P=12000, r=0.035, t=7

=
= 
Hence, after 7 years the population will be 15268.
