Answer:
27=84.78
Step-by-step explanation:
a=r²
a=6²
a=36
1/4 of the circle is missing, so times the answer by 3/4.
36x3/4=27
27=84.78
Answer:
x = 24
obtuse isosceles triangle
Step-by-step explanation:
x = 24 because a triangle has to have all the angles add up to 180. So x + x +132 = 180.
180-132 = 2x
48 = 2x
x = 24
It is an isosceles because two of the angles are the same and one is different which means two of the sides are the same and one is different. (isosceles = icicle is how I remember it). Obtuse because there is an angle that is over 90 degrees.
Answer:
-10.4 m/s
Step-by-step explanation:
Given:
x = -26.5 m
x₀ = 0 m
a = -1.80 m/s²
t = 3.81 s
Constant acceleration equation:
x = x₀ + v₀ t + ½ at²
-26.5 = 0 + v₀ (3.81) + ½ (-1.80) (3.81)²
v₀ = -3.53
The initial velocity was -3.53 m/s. So the final velocity is:
v = at + v₀
v = (-1.80) (3.81) + (-3.53)
v = -10.4 m/s
