Answer:
187
Step-by-step explanation:
We make an equation to find the average of all three games: (139+184+x)/3=170 . x is the value of the third game to get an outcome of at least 170, and when you solve the equation you get 187.
P(x) = x^4 - 9x^2 - 4x + 12
P(1) = 1^4 - 9(1)^2 - 4(1) + 12 = 1 - 9 - 4 + 12 = 0
x = 1 is a root.
By dividing the polynomial by x - 1, gives other roots as 3 and -2
Answer:
Step-by-step explanation:
The total surface area of a cone is given by :
Put r = 2r and l = 2l in the above formula
