Answer:
907.46cm
Step-by-step explanation:
Area of Cirlce = πr^2
R= 17
R^2= 289
289 x 3.14 = 907.46
907.46cm
It's not clear what polynomial you posted, but let's say you had the polynomial
5x^3+7x^2-9x+10
This is a cubic polynomial as the largest exponent is 3. The degree is also 3. The degree of the polynomial is equal to the largest exponent.
f(x) = 2 + 3cos(10π(x - 3))
f(47) = 2 + 3cos(10(3.14)(47 - 3))
f(47) = 2 + 3cos(31.4(45))
f(47) = 2 + 3cos(1413)
f(47) = 2 + 3(0.891006524)
f(47) = 2 + 2.673019573
f(47) = 4.673019573

Answer:
2.5 hours
Step-by-step explanation:
The price of stock A is described by ...
A = 14.63 + 0.09t . . . . . . where t is time in hours after 9 A.M.
And the price of stock B is ...
B = 15.13 - 0.11t
The two prices will be equal when ...
A = B
14.63 +0.09t = 15.13 -0.11t
0.20t = 0.50 . . . . . . . . . . . . . add 0.11t -14.63 to both sides
t = 0.50/0.20 = 2.5
The prices of the two stocks will be the same in about 2.5 hours.
