Answer:
C 9i
D -9i
Step-by-step explanation:
sqrt(-81)
sqrt(81) sqrt(-1)
we know that sqrt(-1) = i
±9i
It’s C. ( 3 . -5 ), because the you want to look at where the two lines intersect. So you want to always look at the X - Axis first. And that’s on the 3. Now you want to look at the Y - Axis. And that’s on - 5. So you answer will be C. ( 3 . -5 )
Answer:
We conclude that
- The angle ∠2 = 4x = 4(36°) = 144°
Step-by-step explanation:
Given
<1 and <2 form a linear pair
m∠1 = 4m∠2
To determine
Find the measure of each of the two angles.
<u>Important Points about linear pair:</u>
- We know that when two lines meet or intersect, we get a linear pair of angles.
- Linear pairs are basically two adjacent angles that form a line.
- The measure of two adjacent angles forming a straight line is 180, meaning they are supplementary.
As
<1 and <2 form a linear pair
m∠1 = 4m∠2
In other words, angle 1 is 4 times the measure of angle ∠2.
Let the angle ∠1 be = x
As the angle 1 is 4 times the measure of angle ∠2, so
The angle 2 will be = 4x
As <1 and <2 forms a linear pair, thus the measure of the sum of <1 and <2 will be 180°, so


divide both sides by 5


Thus, we conclude that
- The angle ∠2 = 4x = 4(36°) = 144°
Slope = 20/6 = 10/3

<u>Answer:</u>
The simple interest for $152, 2.5%, 18 month is $5.7
<u>Solution:</u>
Given that, principal amount = $ 152, interest rate = 2.5 % and time period = 18 months.
Now we have to calculate the simple interest for above given values.
We know that, simple interest is given as

By substituting the given values, we get

By converting 18 months to years we get,

Hence, the simple interest is $5.7
