The center can be found using the midpoint formula: M=[(x1+x2)/2], [(y1+y2)/2]. For us, that looks like this: M = [(-2-14)/2], [(10-6)/2] which gives us M = (-8, 2). Now you have your center. To find the radius, use that midpoint (or center) and an endpoint to find out the distance between them (use the distance formula for that). The distance between those 2 coordinates is 10. So your center is (-8,2) and your radius is 10
Given:
Principal = 2,500
rate = 3.5%
term = 6 years
Simple interest = Pricipal x rate x term
S.I. = 2500 x 3.5% x 6
= 87.50 x 6
S.I. = 525.00 CHOICE C.
Suzanne will earn an interest of $87.50 per year and a total of $525 interest at the end of 6 years.
Answer:
Position of the submarine now relative to the water surface
Step-by-step explanation:
It says that the position of a submarine relative to the water surface was -32 1/4 feet . A downward navigational maneuver increased it's depth by 15 1/2 feet.
Now we need to find about what is the position of the submarine now relative to the water surface.
Downward navigation means we 15 1/2 is negative
so we will just add both values to get the final answer:
Position of the submarine now relative to the water surface =
interior angle of a regular 18-gon.
It is easier to calculate the exterior angle of a regular polygon of n-sides (n-gon) by the relation
exterior angle = 360/n
For a 18-gon, n=18, so exterior angle = 360/18=20 °
The value of each interior angle is therefore the supplement, or
Interior angle = 180-20=160 degrees.
Naming of a 9-gon
A polygon with 9 vertices is called a nonagon (in English) or enneagon (French ennéagone, but the English version is sometimes used)
You had a good start with the correct answer.
Exterior angle of a 15-gon
The exterior angle of a 15-gon can be calculated using the relation given in the first paragraph, namely
Exterior angle = 360/15=24 degrees
