Answer:
−1 + i times the square root of 3
is the answer.
Step-by-step explanation:
Given is a quadratic equation in x
using completion of squares method
Equate to 0
Take square root
Subtract one from both sides
x = [/tex]-1±i\sqrt{3}[/tex]
The last option namely
−1 + i times the square root of 3 only matches with our answre
Hence last option is right.
x² - 4x + 8 → there are 3 terms (remember to include the sign with each term)
term 1: x²
term 2: -4x
term 3: 8
Step-by-step explanation:
1/625×15625
We wil add power 2 as shown in the bracket
It will be 1/390625×244140625=625
Answer:
2.33 = BC
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan B = AC / BC
tan 25 = AC / 5
Multiply each side by 5
5 tan 25 = BC
2.331538291 = BC
To the nearest hundredth
2.33 = BC
