Answer:
T = 4.0 s
Step-by-step explanation:
The period of a simple pendulum is given by

where l = length of the pendulum
= 4 m
g = acceleration due to gravity
= 9.8 m/s^2

Answer:
y = 4x + 5
Step-by-step explanation:
slope = m = 4
y-intercept = b = 5
y = mx + b
y = 4x + 5
g(x) = 2x-6
f(x) = -4x +7
(g•f)(x) = g(f(x))
= 2(f(x)) - 6
= 2 ( -4x+7) -6
= -8x + 14 -6
= -8x +8
now
(g•f)(1) = -8(1) + 8= -8+8
= 0
so option a is answer
The answer would be C because you would do 60 x 25 which would give you 1,500
Answer:
100 degrees
Step-by-step explanation:
They have to add up to 180 because they're on a straight line together.
180 - 80 = 100 degrees
