Answer:
x² +y² = 16
Step-by-step explanation:
The diagonal of a square is √2 times the side length, so the diameter of a circumscribed circle is √2 times the diameter of an inscribed circle. Each of the two outer circles is √2 times the diameter of the one just inside it, so the outer circle is (√2)(√2) = 2 times the diameter of the inner circle.
The equation of the largest circle with radius 2·2=4 is ...
x² +y² = 16
Answer:
interest paid = $206.25
course = $1,875.00
total = $2,081.25
Step-by-step explanation:
Interest = Principal x Rate x Time
I = 1875(.055)(2)
I = 206.25
Answer:
15 sides
Step-by-step explanation:
Interior angle = {n - 2}{180/n}
156 = {n - 2}{180/n}
Cross multiply
156n = {n - 2}180
156n = 180n - 360
180n - 156n = 360
24n = 360
n = 369/24
n = 15
Answer:
The expression 40X represent the number of pages she read during X nights.
Step-by-step explanation:
Given : Tatiana read 40 pages of her book every single night
Let Tatiana read for X number of nights.
We have to write an expression that represent the number of pages she read during X nights.
The number of pages she read during X nights = number of pages Tatiana read every night × number of nights she spend
The number of pages she read during X nights = 40X
Thus, The expression 40X represent the number of pages she read during X nights.
