Use the trigonometric function.

\sin30^o=\dfrac{x}{20}\\\\\sin30^o=\dfrac{1}{2}\\\\\dfrac{x}{20}=\dfrac{1}{2}\ \ \ |\cdot20\\\\x=10

\sin60^o=\dfrac{y}{20}\\\\\sin60^o=\dfrac{\sqrt3}{2}\\\\\dfrac{y}{20}=\dfrac{\sqrt3}{2}\ \ \ \ |\cdot20\\\\y=10\sqrt3

If f(x)=2x^2+6,find the value of f(-3). Show all work
goblinko [34]
Just plug -3 where x is into the equation 2x^2 + 6 and solve
f(-3) = 2(-3)^2 + 6
f(-3) = 2(9) + 6
f(-3) = 18 + 6
f(-3) = 24

c) One is a cup and the other is a sword is   0.06

<h3 /><h3>What is probability?</h3>

Probability can be defined as the ratio of favorable outcomes to the total number of events.

a) for both are cups

P= 12*11/48*47
p = 0.05

b) for  At least one cup
p = 12*36/48*47
p = 0.19

c) for One is a cup and the other is a sword
p = 12*12/48*47
p = 0.06

Thus, the required probability is 0.05, 0.19, 0.06
