Answer:
26
Step-by-step explanation:
W = ∫ f(x) dx
W = ∫₁³ (3x + 7) dx
W = (1.5x² + 7x) |₁³
W = (1.5(3)² + 7(3)) − (1.5(1)² + 7(1))
W = 26
No, because all multiples of 5 end with 5 or 0
For this case what you should do is use the following trigonometric relationship:
sin (x) = C.O / h
Where
x: angle
C.O: opposite leg
h: hypotenuse
Substituting the values we have:
sen (60) = long / h
sen (60) = 3 / h
h = 3 / sin (60)
h = 3.46
Answer:
h = 3.46
X^2 +3x-4=0
(X+4)(x-1)=0 so x = -4 and x=1 are solutions
