Answer:
[y]=-18 so y belongs to (-18,-17)
Step-by-step explanation:
Answer:
D) The circle is centred at (-8,3) and has a diameter 20
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the circle
( x + 8)² +( y-3)² = 100
⇒ ( x + 8)² +( y-3)² = 10²
Standard form of the circle ( x-h)² +(y-k)² = r²
Centre of the circle (h , k) = (-8 , 3)
Radius of the circle r = 10
Diameter of the circle 'd' = 2r = 2(10) =20
<u><em>Final answer:-</em></u>
The circle is centred at (-8,3) and has a diameter 20
Answer:
D. 1.30
Step-by-step explanation:
As you can see on the number line, since there are 10 markings between the marks of 1 and 2, we can divide that to get the value that each marking represents.
Hence, each marking represents a change of , which would equal to .
Therefore, A would be 1 + (3 ), which equals to 1.3.
(As for why it would be 1 <em>+ </em>(3 ), that is because we can deduce the number line grows as it goes to the right due to the main markings (0, 1, 2) also growing as they go towards the right.)
