Answer:
f(x) = 
is the required polynomial.
Step-by-step explanation:
Given the zeroes (roots) of the polynomial are 
and 
.
We know that complex roots occur in conjugate pairs.
So, this means that 
and 
would also be the roots of the polynomial.
If 
are to be the roots of the polynomial then the polynomial should have been: 
.
Now, to determine the polynomial for which 
would be the roots.
Roots of the polynomial are nothing but the values of x (any variable) that would make the polynomial zero.
⇒ 
⇒ 
The required polynomial would be the product of all the above polynomials.
Multiply this to get the required equation.
⇒
∴ The required polynomial is x⁴ - 2x³ + 49x² - 18x + 360 = 0.
X is equal to 23
15/3 = 5
36/3 = 12
39/3 = 13 then add the 10 and you get 23
Answer:
-60
Step-by-step explanation:
Given the expression
5- {2*[(-5power2) -7 ] /3}
= 5- {2*[(25) -7 ] /3}
= 5- {2*[18 ] /3}
= -5 [2*6]
= -5(12)
= -60
Hence the required answer is -60
Answer:
254
Step-by-step explanation:
x-39=215
215+39=x
215+39=254
Answer:
$2200
Step-by-step explanation:
Given that Owen has $7000 to pay, with a $1000 deductible. This means that he has, left to pay, $6000.
Again, we're told that he has 20% Co pay for the procedure. Taking 20% of $6000, we have
20/100 * 6000 = $1200. This means be has $1200 to co pay for the procedure.
Adding this newly calculated $1200 with the previously set aside $1000, we have a total of $2200. This is the price Owen will pay from his part, as part of the surgery
