Answer:
3
Step-by-step explanation:
Answer:
15( b+ a) - 2(a + 0 ) = c
then
c+b = t
We could put the two together to make 15(b+a)- 2(a+0) + b = t
Where t = 8379.70
a= £249.99 b= 329.99
Step-by-step explanation:
Equal amounts are 8549.7 from 30 mowers a+b = small and large.
If we use this as an even and take away a+b at different equations we can find the answer to be 8379.70 on the 2nd equation. First equation = 8579.70
8549.7- 249.99-249.99+329.99 to equal the given year to find c in first equation and total in year = t within the above equation.
Answer: 3/7
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
using the identity
cos2a = 2cos²a - 1 , then
cos2a
= 2[
(a +
) ]² - 1
= 2 [
(a² +
+ 2) ] - 1
=
(a² +
) + 1 - 1
=
(a² +
) ← thus verified
It is an irrational number. A number is rational if it can be expressed as a quotient of 2 integer numbers. Number π2 cannot be expressed as a quotient of integers, so it is an irrational number.
