Answer:
Hence, we have:
a= 3 and b= 4
Step-by-step explanation:
It is given that:
A complex number, (a + bi), multiplied by (2 + 3i) and added to -i gives the product of (-11 + 5i) and (1 – i).
i.e.
Since, we know that :
Hence, we have:
i.e. we have:
and
On multiplying equation (1) by 2 and equation (2) by 3 we get:
on putting the value of a into equation (1) we get:
2a+3ai+2bi+3bi²-i=-11+11i+5i-5i²
2a+(3a+2b-1)i-3b=-11+16i+5
(2a-3b)+(3a+2b-1)i=-6+16i
Therefore; we have the next system of equations:
2a-3b=-6
3a+2b-1=16
Finally, the system of equations is:
2a-3b=-6
3a+2b=17
We can solve this system of equations by reduction method
2(2a-3b=-6)
3(3a+2b=17)
----------------------
13a=39 ⇒a=39/13=3
3(2a-3b=-6)
-2(3a+2b=17)
----------------------
-13b=-52 ⇒ b=52/13=4
Answer: a=3; b=4

a=πr^2s/360
multiplying both sides by 360 we get:
360×a=(πr^2s/360)×360
360a=πr^2s
dividing both sides by πr^2
(360a)/πr^2=(πr^2s)/πr^2
this gives us:
s=(360a)/(πr^2)
Answer: s=(360a)/(πr^2)
Final answer:
The area of a sector of a circle 'a' can be calculated using the formula a=πr²s/360, where 'r' is the radius and 's' is the angle measure in degrees. The rotation angle is the arc length in relation to the radius of the circle. This concept is part of mathematics introduced in high school.
Explanation:
The subject of your question is regarding the area of a sector in a circle. This is a mathematical concept usually introduced in high school level geometry. Here, the formula you've mentioned, a=πr²s/360, will enable you to calculate the area 'a' of a sector in a circle. 'r' represents the radius of the circle and 's' is the angle measure in degrees.
When we refer to rotation angle, we are talking about the arc length in relation to the radius of the circle. A full revolution of a circle is 360 degrees (°) which is equal to 2π radians. This is due to the definition of one radian as the angle when the arc length is equal to the radius of the circle.
To understand this, let's consider an example. If 's' is 90 degrees, and the radius 'r' is 1, then the area 'a' of the sector would be: a = π*1²*90/360 = π/4 square units.

Step-by-step explanation:
1. 25% * 400 = 0.25 * 400 = * 400 = 100
2. 50% * 90 = 45
1. 75% * 200 = 0.75 * 200 = 3/4 * 200 = 150
2. 10% * 8000 = 0.1 * 8000 = 800
1. 5% * 20 = 0.05 * 20 = 1
