If a quartic equation has a real root, what do you know about the other roots of the equation? Explain.
Alex17521 [72]

Answer:

A) Real Roots

B) Imaginary Roots

C) Equal Roots

D) Unequal Roots

E) Rational Roots

F) Irrational Roots

Step-by-step explanation:

The equation with one variable , in which the highest power of variable is two , is know as QUADRATIC EQUATION

ex - 3x² + 4x + 7 = 0

Every quadratic equation gives to values of unknown variables and these values is called roots of equation .

The quadratic equation have three roots :

A) Real Roots

B) Imaginary Roots

C) Equal Roots

D) Unequal Roots

E) Rational Roots

F) Irrational Roots

The nature of Roots depends entirely on the value of it Discriminant

If D = 0 ,  Roots are real and equal

If D > 0  , roots are real and unequal

If D <  0 ,roots are imaginary

where D = b² - 4ac for any quadratic equation ax² + bx + c = 0

Divide (6.3 × 103) by (1.8 × 105) giving your answer in Scientific Notation.
Sauron [17]

Answer:

(6.3*10³) ÷ (1.8*10⁵)

6.3*10³ = 0.063*10⁵

then:

(6,3*10³) ÷ (1.8*10⁵) = (0.063*10⁵) ÷ (1.8*10⁵)

= 0.063/1.8

= 0.035

0.035 = 3.5 *10⁻² = 35*10⁻³

Can you guys pls help me eith this one plsss
Darina [25.2K]
The answer is 16 3/8.

So, to find out the total weight we have to add them all up. However, since we need a common denominator to add them up, we have to change the denominator of the first two mixed fractions, 2 1/2 and 1 1/2. Since we know that 2 is a factor of 8, we know that we can use 8 as the common denominator. The third mixed fraction already has a denominator of 8 so we just have to change the denominator of, 2 1/2 and 1 1/2. To do this, we just have to multiply the numerator and denominator by 4 to get, 2 4/8 and 1 4/8. Next, we can add them all up. We first add the fraction part, 4/8 + 4/8 + 3/8, which would give us 11/8, which can be turned into 1 3/8. Finally, we just have to add the whole numbers and 1 3/8, 2 + 1 + 12 + 1 3/8, to get 16 3/8.
