Answer:
JK ≅ MN
Step-by-step explanation:
Given:
Side : JL ≅ MR
Angle: ∠J ≅ ∠M
Side Angle Side - Angle is inbetween tow sides. So JK ≅ MN
F(x) = 3x² - 12
Finding where the graph crosses the axes will help us to determine the correct graph
When x = 0,
f(0) = 3(0)² - 12
f(0) = -12
So we have one point (0, -12)
When y = 0
0 = 3x² - 12
12 = 3x²
4 = x²
√4 = x
x = ⁺/₋ 2
So the graph crosses the x-axis at -2 and 2 and the y-axis at -12
The correct graph is option A

Answer:
5%
Step-by-step explanation:
Total 'halwa' made = 1
Divided into four equal portion = 1/4
Arrival of an unexpected guest = 1/5
By what percentage has each family member's share been reduced:
Change in the sharing proportion:
Previous share ratio - new sharing ratio
(1/4 - 1/5) = (5 - 4) / 20 = 1/20
That means total reduction in the sharing = 1/ 20
Since each member comes contributed equally:
Reduction in each family member's share ;
(1 / 20) ÷ 4
(1 / 20) * 1/4 = 1/ 80
Percentage reduction:
(Reduction / original share) * 100%
[(1/80) ÷ (1/4)] * 100
(1/80 * 4/1) * 100%
(1/20) * 100%
= 5%
Reduction in each family members share = 5%
