Answer:
The rectangular form of ![4[cos(150^{o})+i sin (150^{o})]](https://tex.z-dn.net/?f=4%5Bcos%28150%5E%7Bo%7D%29%2Bi%20sin%20%28150%5E%7Bo%7D%29%5D)
is 
.
Answer:
48
Step-by-step explanation:
Answer:
Step-by-step explanation:instead, try making the subscripts and superscripts stand out:
n-1
a = a * r
n n-1
Believe me, it's worth the extra work to do this!!
Given the sequence -3, -6, -12, -24, you can easily see that the first term,
a is -3. The common factor is 2. Note how (-3)*2=-6, and so on.
1
So, a = -3 and r=2.
1
So the formula for this geometric sequence is
n-1
a = -3*2
n
Answer:
b^20
Step-by-step explanation:
when the exponents have one inside and the other outside, they are multiplied.
3x - 5 = 2x + 7 i call the number "x"
3x = 2x + 12
1x = 12
x = 12 the number is 12
