I can’t see the image to help u :(
If it took one hour to complete a card game, we can tell that the average play time varies around that time.
So only one game can be completed in one hour.
Hope it helped,
Happy homework/ study/ exam!
Answer:
168.3 cm
Step-by-step explanation:
It was 2.3 cm less than 170.6 cm, so we use subtraction.
170.6 cm - 2.3 cm = 168.3 cm
Radius of the circle = sqrt((7 - 0)^2 + (0 - 0)^2) = sqrt(7^2) = 7
Equation of a circle is given by (x - a)^2 + (y - b)^2 = r^2; where (a, b) is the centre of the circle.
Required equation = (x - 0)^2 + (y - 0)^2 = 7^2
x^2 + y^2 = 49
Answer:
c) r= 2sin θ
Step-by-step explanation:
Remember, 
therefore,
Also y= rsin θ
Given rectangular equation:
x²+y²+ 2y
r²= 2(rsin θ)
r²= 2rsin θ
dividing r from both sides
r= 2sin θ
