Length / wingspan
14.8 / 9.8 = 0.5 / x
cross multiply
(14.8)(x) = (9.8)(0.5)
14.8x = 4.9
x = 4.9 / 14.8
x = 0.331 meters....wingspan of model
Answer:
a
Step-by-step explanation:
assuming theyre asking you to graph y = (x-2)(x+3) -cant see the signs in your photo
the x-intercepts would be 2 and -3 , so option a!
Answer:
2. Eunju is right
3. is a factor of .
Step-by-step explanation:
<u>Polynomial Remainder Theorem</u>
The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-a) is equal to f(a).
As a consequence, if a polynomial is divisible by x-a, f(a)=0.
Part 1:
Let's make:
To find out if x+b is a factor of f(x), we find f(-b):
Operating:
The value of f(-b) is not zero. This means Eunju is right, x+b is not a factor of f(x).
Part 2:
We must find out if is a factor of without using long division or synthetic division.
We can use the polynomial remainder theorem again, but since the factor is not in the form (x-a), we can factor it as follows:
Now we just apply the theorem twice. If both remainders are zero, then the assumption is true.
Let's make:
Find f(-2):
Find f(-3):
Since both f(-2) and f(-3) are zero, is a factor of .
Answer: 18
Step-by-step explanation: 16/2 = 8 - 6 = 2 x 10 = 20 - 2 = 18, sorry if i'm incorrect.
