Answer:
30 mm 2
Step-by-step explanation:
The fundamental theorem of algebra states that a polynomial with degree n has at most n solutions. The "at most" depends on the fact that the solutions might not all be real number.
In fact, if you use complex number, then a polynomial with degree n has exactly n roots.
So, in particular, a third-degree polynomial can have at most 3 roots.
In fact, in general, if the polynomial has solutions , then you can factor it as
So, a third-degree polynomial can't have 4 (or more) solutions, because otherwise you could write it as
But this is a fourth-degree polynomial.
The answer is C18 because just like in algebra you'll multiply the number the two numbers in and out of the paranthisis .
Answer:
l = (P-2w)/2
Step-by-step explanation:
P = 2l + 2w
move 2w to the left to leave the l variable by itself
P - 2w = 2l
divide by 2 on both sides to leave l by itself
(P - 2w) / 2 = l or l = (P - 2w) / 2
Height in feet is represented by
The height of the ball is 0 feet when it hits the ground.
So we replace height f(x) by 0 and solve for x to find the time taken to reach the ground
( divide by -16 on both sides)
Now factor it
(x-6)(x+1) =0
x-6 =0 and x+1=0
x=6 and x=-1
Time cannot be negative so we ignore -1
x = 6 seconds
It will take 6 seconds for the ball to reach the ground.
