Answer:
Step-by-step explanation:
Given is a picture of circle with angle
BOC =7x-11
Also angle of arc BC = angle BOC = 3x+53
Since both are the same equate the two
Now substitute this x value in any one of 3x+53 or 7x-11
Angle COB = angle BOC = 3x+53
= 48+53 = 101 degrees
-------------------------
To find length of arc
Central angle = 101
Hence arc lengh =
Answer:
180
Step-by-step explanation:
Given :
the number has three digits
it is multiple of 20
hundreds digit and tens digit add to make 9
half of it is less than 100.
I suppose 180 can correctly fit into all above criterions
It is 3 digit number. 1+8 =9, 180/2 =90 which is less than 100.
Answer:
P(t) = 200·0.95^t
Step-by-step explanation:
Each year, the population drops to 95% of its previous value. That is, the population is multiplied by 0.95 each year. Repeated multiplication is signified by an exponent. Here, that exponent is the number of years from today (t).
The population function can be written as ...
P(t) = 200·0.95^t
