Answer:
a) subtracting '8' on both sides, we get
- 5 x² + 8-8 = 133-8
- 5 x² = 125
b) The solution is x = 5 i
Step-by-step explanation:
<em>Explanation</em>:-
<u><em>Step (i):</em></u>-
Given quadratic equation - 5 x² + 8 = 133
subtracting '8' on both sides, we get
- 5 x² + 8-8 = 133-8
- 5 x² = 125
<u><em>Step(ii)</em></u>:-
dividing '-5' on both sides, we get
x² = -25
x = 5 i
Answer:
490 pi units^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
The diameter is 14 so the radius is 14/2 = 7
V = pi (7)^2 * 10
V =490 pi
Answer:
99°
Step-by-step explanation:
<8 = 99° [Since, corresponding angles of parallel lines]
Period For Interest = 9 months
Period taken = 54 months
Investment = 2000
Quarters for payment = 54 ÷ 9
=6 periods
2000×2 = 4000
4000×2 = 8000
8000×2 = 16000
16000×2 = 32000
32000×2 = 64000
64000×2 = 128000
Answer = 128000
Area = length x height divide 2
so = (6x6)/2 - (3x2)
= 12 cm square
