Answer:
22.86 centimeters (9 inches into cm is 22.86 cm)
6
Step-by-step explanation:
b = 2 units
h = 6 units
A=1/2 *b*h
= 1/2 *6*2
= 6
use the pythagoras theorem
(4-x) /(3x+21)
The denominator cannot be zero
3x + 21 ≠ 0
3x ≠ -21
x ≠ -7
The domain of the function will be all real number except -7
{x | x ≠ -7}
1)
a1 = 2*5
a2= 2*2*5
a3= 2*3*5
...
an=2n -*5
2)
u1 = a
u2 = a +4
u3 = a + 2 * 4
u4 = a + 3 * 4
un = a + ( n - 1 )* 4
