Answer:
(A)
Step-by-step explanation:
A polynomial has a leading coefficient of 1 and the following factors with multiplicity 1:
We apply the following to find the factored form of the polynomial.
- If a complex number is a root of a polynomial with real coefficients, its complex conjugate is also a root of that polynomial.
- If the polynomial has an irrational root , where a and b are rational and b is not a perfect square, then it has also a conjugate root .
Therefore, the factored form of the polynomial is:
Answer:
For First Solution:
is the solution of equation y''-y=0.
For 2nd Solution:
is the solution of equation y''-y=0.
Step-by-step explanation:
For First Solution:
In order to prove whether it is a solution or not we have to put it into the equation and check. For this we have to take derivatives.
First order derivative:
2nd order Derivative:
Put Them in equation y''-y=0
e^t-e^t=0
0=0
Hence is the solution of equation y''-y=0.
For 2nd Solution:
In order to prove whether it is a solution or not we have to put it into the equation and check. For this we have to take derivatives.
First order derivative:
2nd order Derivative:
Put Them in equation y''-y=0
cosht-cosht=0
0=0
Hence is the solution of equation y''-y=0.

Answer:
$6.43
Step-by-step explanation:
You start by multiplying $1.49 by 5 because you bought 5 cartons for $1.49, that would equal $7.45. Then, you multiply $3.06 by 2 because you bought 2 gallons, and you will get $6.12. Then you add both answers: $7.45 and $6.12. And you will get $13.57. Then, you hand him a $20, so $20 minus $13.57 equals $6.43! Please mark as brainliest! I worked hard! Plus hope this helps =)
Answer:
Sale price= $25.5
Step-by-step explanation:
Giving the following information:
The original price was $29.99, but the ball was on sale for 15% off.
<u>To calculate the sales price, we need to use the following formula:</u>
<u></u>
Sale price= original price* (1 - sales discount)
Sale price= 29.99*(1 - 0.15)
Sale price= $25.5
