Answer:
800m
Step-by-step explanation:
this would be solved using Pythagoras theorem
we are to find the base
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
600² + b² = 100²
b² = 10000 - 3600
b² = 6400
take the square root of both sides
b = 800m
The correct answer is B.
The eleventh toss of a coin is independent from previous tosses. So regardless of what happened before, the chance to get heads is always 1/2.
72 ⇒ 72
is ⇒ =
the sum of ⇒ ___ + ___
9 and d ⇒ 9 + d
So, the translation is ...
... 72 = 9 + d
<span>cos^2 x + cos x - 1 = 0, and if X=cosx, x=arccosX
let's find X
X²+X-1=0, delta=1-4(-1)=5, X= -1-sqrt5 /2 or </span><span> X= -1+ sqrt5 /2, but </span><span>0°< x < 360°,
so we must take </span>X= -1+ sqrt5 /2, and <span> x=arccosX = 51.82°</span>
Answer:
A.
Step-by-step explanation:
A. makes the most sense out of all of them. But if it had to be another one, I'd say D. Sorry! I'm not the best at these either. :)
