Answer:
1st one 6.4
Step-by-step explanation:
C^2= a^2 +b^2
C^2 = 5^2 + 4^2
C^2 = 25 + 16
C^2= 41
Root of 41 is 6.4
Answer:
a(6)=2430
Step-by-step explanation:
a(1)=10
a(n)=3×a(n-1)
This is a geometric sequence, with ratio=3
a(2)=3×a(1)=3×10
a(3)=3×a(2)=3²×10
a(6)=3⁵×20=(27×9)×10=243×10=2430
Answer:multiply polynominals by exponents
