Answer: Angie = 6, Jemma = 18
<u>Step-by-step explanation:</u>
Let x represent the current age of Angie
Current Age Age 5 years from now
Angie: x x + 5
Jemma: 3x 3x + 5
5 years from now the sum of their ages is 34
(x + 5) + (3x + 5) = 34
4x + 10 = 34
4x = 24
x = 6
Angle's current age is x = 6
Jemma's current age is 3x = 3(6) = 18
Answer:
we have:
u(1) = 18
u(2) = 21 = 18 + 3
u(3) = 24 = 18 + 3.2
u(4) = 27 = 18 + 3.3
.......
=> the sequence has: u(1) = 18
d = 3
=> u(n) = 18 + 3(n - 1) = 3n + 15
so the recursive formula for the sequence is u(n) = 3n + 15

Answer:
Step-by-step explanation:
6Sin² Ф + 11Sin Ф + 4 = 0
Product = 6*4 = 24
Sum =11
Factors = 8 , 3 {8*3 = 24 & 8+3 = 11}
6Sin² Ф + 8Sin Ф + 3 sin Ф + 4 = 0
2Sin Ф ( 3Sin Ф + 4) + (3Sin Ф + 4) = 0
( 3Sin Ф + 4) (2Sin Ф + 1) = 0
3Sin Ф + 4 = 0 ; 2Sin Ф + 1 = 0
3Sin Ф = -4 ; 2Sin Ф = -1
Sin Ф = -4/3 ; Sin Ф = -1/2
Sin Ф = -4/3 , -1/2
