Answer:
The ones that give a rational number answer are:
C+D
A*B
C*D
A*A
Step-by-step explanation:
A+B does not give a rational number answer; √3+2√3 = 3√3
C+D is a rational number; √25=5 and √16=4; 5+4=9.
A+D is not a rational number; √3+√16 = √3+4
A*B is a rational number; √3*2√3 = 2√9 = 2*3 = 6
B*D is not a rational number; 2√3*√16 = 2√3*4 = 8√3
C*D is a rational number; √25*√16 = 5*4 = 20
A*A is a rational number; √3*√3 = √9 = 3
To find the zeros of a polynomial, you make every factored parentheses equal to zero. You basically make the other side equal to zero and solve for x.
So,
<u>Your zeros are x = 9, -12, 24</u>
So your answer is 3) 9, -12, 24
5 x 10⁻³ is a scientific notation.
5 is the coefficient
10 is the base
3 is the exponent. The sign of the exponent signifies which direction the decimal point moved.
negative sign means that the decimal point moved from left to right in writing the scientific notation.
positive sign means that the decimal point moved from right to left in writing the scientific notation.
5 x 10⁻³ is 0.005 in standard form.
had the exponent been positive.
5 x 10³ is 5000 in standard form
