Answer:200,000
Step-by-step explanation:
If it increases 5% every year in 20 years it will Have increased 100% therefore the number would have doubled
We are given an equation <span> f(n) = 15(1.04)^n where f(n) is the plant height in cm and n is the number of days since the day planted. The domain of the plant is a set including 0 to positive infinity. The y-intercept of the graph is when n = 0 or equal to 15. when n is 1, f(n) is equal to 15.6 . when n is 5, f(n) is equal to 18.25. the rate of change is (18.25-15.6)/(5-1) equal to 0.66</span>
Answer:
360 degree
Step-by-step explanation:
The sum of all the exterior angles is 360 for any polygon.
This can be proved for polygon with 20 sides also.
We know that sum of all the angles of polygon is given by formula = (2*n -4) *90
where n is the no. of sides of polygon
for 20 sides polygon sum of sum of all the angles = (2*20 -4) * 90
= (40-4)*90 = 36*90 = 3240 degree
measure of each angle of polygon = sum of total angles of polygon/ no of sides of polygon = 3240/20 = 162
We also know that sum of interior and exterior angle of triangle is 180 degree, as interior and exterior angle lies on straight line and they are supplementary
so
162 + value of exterior angle = 180
=> value of exterior angle = 180 - 162 = 18
Value of one exterior angle is 18 degree
in 20 sided polygon there are 20 exterior angle
therefore, value of 20 exterior angle is 18*20 degree which is 360 degree.
__________________________________________________________
As a general point one can memorize than sum of all the exterior angle for a polygon with any number of side is 360.
Answer:
C. 3
Step-by-step explanation:
8 / 1/3
When dividing fractions, do CCF (Copy, Change, Flip)
You keep the first number: 8
Change the division sign to multiplication: X
Flip the fraction to make it its reciprocal: 3/1
New expression:
8 X 3/1 or 8 X 3
