X = √7²+4² by using Pythagoras Theory as the triangle is a right angled triangle
Five names for -214 are negative 214, drop of 214, minus 214, below 214, and taking away 214.
Answer:
D
Step-by-step explanation:
∠AXD = 180°
∠AXB = 32°
so you do 180 - 32 and you get 148. hope I helped:)
First we are going to reesribir the inaginario number:
i = root (-1)
i = (- 1) ^ (1/2)
Then, we have to
By properties of exponents:
i ^ 3 = i ^ 2 * i
Substituting the value of i:
i ^ 3 = ((- 1) ^ (1/2)) ^ 2 * i
Applying properties of exponents:
i ^ 3 = ((- 1) ^ (1/2)) * ((- 1) ^ (1/2)) * i
i ^ 3 = ((- 1) ^ ((1/2) + (1/2)) * i
i ^ 3 = ((- 1) ^ ((2/2)) * i
i ^ 3 = ((- 1) ^ (1) * i
i ^ 3 = -1 * i
i ^ 3 = - i
Answer:
D.-i
Answer:
4/33
Step-by-step explanation:
We seek to find the repeating decimal 0.121212... in the form of a fraction.
First, set x equal to this decimal:
x = 0.121212...
Multiply both sides by 100:
100x = 12.121212....
Now, let's subtract the original equation from this new one:
100x = 12.121212....
- x = 0.121212....
We realize that since the repeating decimal part goes on forever, we can simply cancel it out when we subtract. So we're left with:
100x - x = 12 - 0
99x = 12
Divide both sides by 99:
x = 12/99 = 4/33
The answer is 4/33.
