Step-by-step explanation:
By Sine Rule, 13/sin96° = x/sin25°.
Hence, x = 13sin25°/sin96° = 5.5.
Answer:
v = 196.25
Step-by-step explanation:
v = 3.14*r^2*h
v = 3.14*5^2*2.5
v = 196.25
Answer:
3 ; 5/2
Step-by-step explanation:
Δ= 121 - 120 = 1
x1 = (11 + 1)/4 = 3
x2 = (11-1)/4 =5/2
Answer:
Step-by-step explanation:
hello :
An = n²
first 4 terms are :
n=1 : A1=1² =1
n=2 : A2=2² =4
n=3 : A3=3² =9
n=4 : A4=4² =16
and the 10th term is : n=10 : A10=10²=100
