All odd degrees polynomials with real coefficients have (at least) a real root, and are continuous. This is because the curve goes diagonally and must pass through the x-axis.
The above polynomial can be evaluated at x1=-10 and x1=+10 (or any other large enough number)
f(-10)=-2395
f(10)=1405
Since they have opposite signs, the function must intersect the x-axis between x1 and x2 by the intermediate value theorem, hence there is (at least) one root.
The answer will B 150 squares inches
Answer:
a)3/6 and 4/6
b)15/20 and 12/20
c)4/6 and 5/6
d)15/20 and 14/20
Step-by-step explanation:
Change the demonimator to the lowest common demonimator. What ever you do to the bottom number to get to the lowest common denominator, multiply the numerator by the same number.
C + 2c + 12 = 75
Combine like terms:
3c + 12 = 75
Subtract 12 to both sides:
3c = 63
Divide 3 to both sides:
c = 21
This is accomplished by averaging the x and y coordinates.
So the midpoint's x coordinate is found as (13+-6)/2 = 3.5
Similarly, the y coordinate is (8+-6)/2 = 1
So the point is (3.5,1)
