Answer:
1-k^2
Step-by-step explanation:
tan A= sin A/cos A
(sin A)(cos A)(sin A/cos A)=(sin A)^2
(sin A) ^2 + (cos A) ^2= 1
(sin A) ^2=1-(cos A) ^2
(sin A)^2= 1 - k^2
Answer:
x=4 cm
Step-by-step explanation:
x=smallest side
4x=hypotenuse
4√15=third side
use the Pythagorean Theorem
(4x)^2=x^2+(4√15)^2
16x^2=x^2+240
16x^2-x^2=240
15x^2=240
x^2=240/15
x^2=16
x=√16
x=4 cm is the smallest side
the hypotenuse is 16 cm
the third side is 4√15 cm
Answer: There are 456975758 plates that the state can issue.
Step-by-step explanation:
Since we have given that
Number of letters = 4
Number of numerals = 3
And 242 letter arrangements are not allowed.
As we have 26 letters i.e A-Z
and numerals i.e, 0-9
So, the number of plates would be

So, the restricted letters deducting would be

Hence, there are 456975758 plates that the state can issue.
