Answer:
X=14
Y=11
Step-by-step explanation:
14-11=3
14x2=28
11x2=22
22+28=50
Hope that works :)
To answer this item, note that what needs to be done is to substitute -4 to all x's in the equation. That is,
F(x) = 2^x
will become,
F(-4) = 2^(-4) = 1/16 or 0.0625
1 radian
because s= r × angle measurement in radian
we have s= arc , r = radian so we got the value
√18 ÷ √12 = 1.22474487139159
