Answer:
7.8(tan 67)
Step-by-step explanation:
7.8(tan 67)
= 18.4 (2 decimal place)
B is the midpoint which means both sides are equal to each other:
5x = 3x + 4
Subtract 3x from both sides
2x = 4
Divide both sides by 2
X = 2
Using the quadratic equation we get:

Factoring out 2 we get

Factoring out the imaginary number:

So b.
Answer:
Step-by-step explanation:
Probability=(2*2)/(4*5)=1/5=20 %
A, B, D are functions.
(First, second, and fourth response)
You can see which is function since for everyone input only has one value. You can also use the vertical line test.
