Answer : (0, -3) ; (4,21) and (2,9)
Step-by-step explanation:
y = 6x- 3
- y =0*x-3 = -3 (0,3) is not a possible set
- y = 1*6-3 = 3 (1,-9) is not a possible set
- y = 6*2-3 = 9 (2,-15) is not a posiible set
- (0.-3) is a possible set as verified in the first one
- (2,15) is not a possible set since the output of 2 is 9
- y = 4*6-3 = 21 so (4,21) is possible set
- (2,9) is a possible set as verified in the third one
Answer:
109,000
Step-by-step explanation:
1kg = 1000g
45 + 63 = 109
109 x 1000 = 109000
Answer:
1. 121 π unit²
2. 143°
3. 151 unit²
Step-by-step explanation:
1.
Area of a circle is given by the formula A = πr²
where
A is the area,
r is the radius of the circle
From the given diagram, we can see that the radius is 11, hence the area will be:
The answer is units^2
2.
The unshaded secctor and the shaded sector equals the circle. We know that circle is 360°. The unshaded sector has an angle of 217°. So the shaded part will be 360 - 217 = 143°
The measure of the central angle of the shaded sector is 143°
3.
Area of a sector is given by the formula
Where
is the central angle of the sector (in our case it is 143°)
r is the radius (which is 11)
Plugging in all the info into the formula we have:
<em>rounding to the nearest whole number, it is </em>151 units^2
