Let
cos x=7/18
x=arc cos (7/18)-----> using a calculator-------> x=67.11°-----> x=1.17 radians
the answer is
x=67.11° or x=1.17 radians
Answer:
The first and second iteration of Newton's Method are 3 and 
.
Step-by-step explanation:
The Newton's Method is a multi-step numerical method for continuous diffentiable function of the form 
based on the following formula:
Where:
- i-th Approximation, dimensionless.
- (i+1)-th Approximation, dimensionless.
- Function evaluated at i-th Approximation, dimensionless.
- First derivative evaluated at (i+1)-th Approximation, dimensionless.
Let be 
and 
, the resultant expression is:
First iteration: (
)
Second iteration: ()
Answer:
There is a group anxiously waiting to start their triathlon. They are in the sand getting ready for the first leg of the race…the swim! They have roped off a rectangle of the beach that is 200 yards long and 10 yards wide. The athletes are packed in trying fighting for the front. If we assume that 10 athletes can occupy 25 square feet, how many triathletes are?
10 yds x 200 yds = 2000 sq yds.
2000 x 9 = 18000 sq ft
18000/25 = 720 sections that are 25 sq ft
720 sections x 10 people/section = 7200 triathletes
Step-by-step explanation:
Option 3 (1/4 x 60) since 59 is close to 60 and 25% can be rewritten as 1/4
