- First find the area of the whole circle
The equation is :
πr^2
Substitute the radius in:
π(5)^2
Solve:
Area of full circle = 25π
(Note : leave this answer in terms of 'pi' so it is easier to handle
Next, find the area of the sector
The equation for this is:
(angle/360) x πr^2
Substitute the values in:
(80/360) x π(5)^2
Solve :
Area of sector = (50/9)π
Now, find the area of the triangle:
1/2 absinC
Substitute the values in:
1/2(5)(5) x sin(80) = 12.31009691
Subtract this answer from the area of the sector
Answer = 5.14319607
Subtract this from the area of the whole circle
Answer = 73.39662073
To the nearest tenth, that would be 73.4 cm^2

Answer:
Step-by-step explanation:
The problem can be modeled by using the compound growth formula.
Given, Initial number P_0 of people who Nicholas sent the chain letter t=50
The growth rate, r =99%=0.99
Period of Growth,k =12 Weeks
Therefore, in any week (t) after Nicholas initially sent the mail, the number of people who receive the email is modeled by the function:
x^4y^7/ (x^10y^4)^1/3
power to a power means multiply
x^4y^7/ (x^(10*1/3)y^(4*1/3)
x^4y^7/ (x^(10/3)y^(4/3)
exponents divided by exponents means subtract the exponents
x^(4-10/3) y^(7-4/3)
x^(12/3-10/3) y^(21/3 - 4/3)
x^ (2/3) y^ (17/3)
x^ (2/3) y^ (5 2/3)
x^ (2/3) y^ (5 +2/3)
exponents added are the terms multiplied
(x^ 2/3 y^ 5 y ^ 2/3)
y^ 5 (x^ 2/3 y ^ 2/3)
we can take the 1/3 back out
y^5 ( x^2 y^2) ^ 1/3
Choice D
Answer:
22.08
Step-by-step explanation:
Calculator nice
Answer:
True
Step-by-step explanation:
When you are given an equation of a line in the plane, it´s like if they´ve given you the map to a line, and in this case it´s really easy to calculate the value of the different points on X and Y and by that you just have to immagine a value for one of the variables to calculate the other one, most cases is always X the one that you give the value to, and then you just calculate the Y.
