Answer:
Step-by-step explanation:
To find the roots of the complex number you use the following formula:
(1)
in this case the polar number in polar form is:
By replacing in (1) you obtain:
hence, you have:
h. 52‾√3cis(7π12)
1.16 rounded to its nearest tenths is 1.2.
The placevalue of a number is given as:
Example:
1234.567
1 = thousand place value
2 = hundred place value
3 = tens place value
4 = ones place value
5 = tenths place value
6 = hundredths place value
7 thousandths place value
We have,
1.16
The number 1 after the decimal point is in the tenthplacevalue.
Now,
Since 6 is greaterthan 5 tenth place value will be rounded to the next number.
So,
1.16 rounded to the nearest tenths.
= 1.2
Thus,
1.16 rounded to its nearest tenths is 1.2.

Step-by-step explanation:
object is 10 m/s. If the force is changed to 90 N, what will be the acceleration of the object?
Answer:
acceleration would be 9 meters per second squared
Step-by-step explanation:
If quantity "A" varies directly with quantity "B", then we can write:
A = kB
Now, this problem says that force (f) varies directly with acceleration (a). So we can write:
f = ka
Given f = 100 and a = 10, so we substitute and find k (the proportionality constant). Shown below:
f = ka
100 = k(10)
k = 100/10
k = 10
So, we have
f = 10a
Now, force is 90, so what's the acceleration?
90 = 10a
a = 90/10
a = 9
So, the acceleration would be 9 meters per second squared
