Answer:
f(-2) = -12
Step-by-step explanation:
Put -2 where x is and do the arithmetic.
Answer:
Step-by-step explanation:
For this case we have the following expression:
For this case we can apply the following property:
And we can rewrite the following expression like this:
And we can rewrite like this our expression:
Now we can use the following property:
And we got this:
And now we can apply the following property:
And we got this:
And that would be our final answer on this case.
B. y=-5 when graphed is a straight line parallel to the x axis. Knowing the definition of parallel lines we can conclude that y=-5 and the x-axis never intersect
32 x 5/8 = 32/1 x 5/8 = 160/8 = 20 are girls
32-20 = 12 are boys
Answer:
x = 26.4°
Step-by-step explanation:
Defence angle = x
Side length Opposite to reference angle = 4
Hypotenuse length = 9
Apply trigonometric ratio, SOH. Thus:
Sin x = Opp/Hyp
Sin x = 4/9
x = 26.3878° = 26.4° (nearest tenth)
