Answer:
7700
Step-by-step explanation:
Note that 7 is in the thousandths place, 6 in the hundredths place, 8 in the tens place, and 4 in the ones place. Look at the 6. The number to the right of it is bigger than 5, which means that we bump the 6 to 7 and add 2 zeros on the end. (7684 becomes 7700)
Its probably a division question. 250 divided by nine which is 27.7 which rounds to 28.
Answer:
617 ^ 15
Step-by-step explanation:
If the bases are the same when multiplying, add the exponents
617 ^ 9 * 617^6
617 ^(9+6)
617 ^ 15
Answer:
315°
Step-by-step explanation:
z = a+bi
The modulus is the sqrt ( a^2 +b^2)
and the argument (I call it theta) is equal to arctan (b/a)
We have z = 3-3i
We are looking for the argument of z
theta = arctan (-3/3)
= -45 degrees
They don't like negative arguments so add 360 degrees to it. It is the same value, we just loop once around the circle.
-45+360 =
315
This is the answer that i found (x4-81) hope it helps have a great day!
