6x^2 - 8 = 4x^2 + 7x
6x^2 - 4x^2 - 7x - 8 = 0
2x^2 - 7x - 8 = 0
discriminant = b^2 - 4ac; where a = 2, b = -7 and c = -8
d = (-7)^2 - 4(2)(-8)
d = 49 + 64
d = 113
the discriminant is greater than zero, so there are two real roots
Answer:
1) I think its helps to rename a function as tenths or hundredths when you want to write the decimal equivalent because for example if you wanted to rename this function 6/25 to 24/100 you can know were you put it in decimal (0.24).
2) It was a good idea to change 4/16 to 1/4 to determine a decimal equivalent because it would be easier to put 1/4 in a decimal equivalent.
3) You write the decimal 0.12 as 3/25
4) I dont know...sorry that I cant help with this...I dont know the answer to this question
Step-by-step explanation:
Answer:
The complex number in rectangular form is .
Step-by-step explanation:
Let be a complex number in polar form, that is: . The equivalent expression in rectangular form is defined by , where:
(1)
(2)
Where:
- Magnitude.
- Direction, measured in sexagesimal degrees.
If we know that and , then complex number in rectangular form is:
The complex number in rectangular form is .
