B) False
Because the negation makes it opposite of what is was.
Answer: 5F < 5( X + x )
Step-by-step explanation:
Let each finger = F and
The index finger = X
The shortest index finger = x
the combined length of all 5 of her fingers on one hand should be less than 5 times the length of index finger
From the statement above, we get
5F < 5X
Tessa add the second shortest index finger.
That is
5F < 5( X +x)
It’s increased to 9. A square is equal on all sides.
This is obtuse ?
let phi = 135
2theta = 180 -135 = 45
theta = 22.5
phi != 2 * 22.5 != 45
Did you mean ?
phi = 180 - 2theta
Can you provide more explanation ?
Complete question
A 29-meter ladder is sliding down a vertical wall so the distance between the top of the ladder and the ground is decreasing at 7 meters per minute. At a certain instant, the bottom of the ladder is 21 meters from the wall.
What is the rate of change of the distance between the bottom of the ladder and the wall at that instant(in meters per minute)
Answer:

Step-by-step explanation:
From the question we are told that
Slant height 
Change in Vertical height 
Horizontal length 
Generally in finding the distance form the top to the bottom of the wall it is mathematically given by




Generally solving for the differential equation is mathematically represented as
