Answer:
D).
Step-by-step explanation:
ln (e · e^x) = x2 + 4x + 3
ln e^(x+1) = x^2 + 4x + 3
Taking all terms to the power e:
e^(x + 1 )= e^ (x^2 + 4x + 3)
x + 1 = x^2 + 4x + 3
x^2 + 3x + 2 = 0
(x + 2)(x + 1) = 0
x = -2, -1.
Answer:
55.4
Step-by-step explanation:
Think of it as a right angled triangle, the length of the ladder (17ft) is the hypotenuse, the length of the ground (14ft) is the rise, we then use sin to get the angle as the angle of elevation is the angle between the ladder and the ground hence sin^-1 (14/17) and you get your angle.
Answer:
Step-by-step explanation:
3. Area = pie r2
A = (22/7) (4)2
= 50.27
4. Circumference = pie d
C = (22/7) (13)
= 40.84
