We know that
applying the Pythagoras theorem
LM²=LV²+VM²
LM is the radius of the circle
LV=5 in
VM=12/2----> 6 in
so
LM²=5²+6²-----> LM²=61------> LM=7.81 in------> LM=7.8 in
the answer is
7.8 in
Answer:
75
Step-by-step explanation:
f(x)=-x^2-10x
f(-5)=(-5)^2-10(-5)
f(-5)=(-5)(-5)+50
f(-5)=25+50
f(-5)=75

Answer: 24.6 m
Step-by-step explanation:
The shape described is that of a right-angled triangle.
This means that the height of the pole can be calculated using the Pythagorean rule.
c² = a² + b²
c = hypothenuse which is the length of the cable to the ground = 33m
a = base = distance from base of pole to cable point on ground = 22m
b = height of pole
33² = 22² + b²
1,089 = 484 + b²
b² = 1,089 - 484
b² = 605
b = √605
b = 24.6 m
