I think -3.50 but not sure
Cost of air cooler:-3,300
vat added:- 5%
so, price before vat was added:-5/100×3,300=AED165
Answer:
15.33cm
Step-by-step explanation:
when you try to draw out this figure, satisfying the fact that Ad and Ac are both straight lines. you find the ultimately it forms a right-angled triangle with sides AC and AD and hypotenuse CD.
Now, you may use Pythagoras theorem to solve:
AC^2 + AD^2 = CD^2
12.3^2 + 9.15^2 = CD^2
CD^2 = 235.0125
CD = square root of 235.0125 = 15.33cm
Hope this helps
Answer:
D is the true statement
Step-by-step explanation:
A
h(4)=13 and h(20)=13, so h(4)=h(20) and it is not true that h(4)<h(20)
B
This is untrue as we can see that the graph reaches its peak at h(12), so it would be symmetric about the line t=12, not t=10.
C
This is untrue as for all values of t less than 24, the height above the ground, h(t), is greater than zero.
D
This is true because as we can see from the table, when t values are equal distances from 12 (eg. 8 and 16), their h(t) values are the same.
