5-3x-20=24
-3x-15=24
-3x=39
x=-13
here the centre of circle(h,k) is (-2,4)
and its radius(r) is 6 uints.
now the equation of circle is,
(x-h)^2 +(y-k)^2 =r^2
or, (x+2)^2 + (y-4)^2=6^2
or, x^2 + 4x + 4+y^2 -8y+16=36
or, x^2 +y^2 + 4x -8y -16=o
Answer: 10.6
Step-by-step explanation: it has a .3% increase each time, therefore it would be D. 10.6
Answer:
He confused the height and the diameter
Step-by-step explanation:
the formula should have looked like this
V= 3.14 (2.5)^2 (24)
the reason why it is 2.5 and not 5 is because 5 is the diameter so divide 5 by 2 and you get 2.5
V= 3.14 (6.25) (24)
V= 3.14 (150)
V= 471
Answer: b = 1
Step-by-step explanation:
<u>Given</u>
6.8 - 4.2b = 5.6b - 3
<u>Add 4.2b on both sides</u>
6.8 - 4.2b + 4.2b = 5.6b - 3 + 4.2b
6.8 = 9.8b - 3
<u>Add 3 on both sides</u>
6.8 + 3 = 9.8b - 3 + 3
9.8 = 9.8b
<u>Divide 9.8 on both sides</u>
9.8 / 9.8 = 9.8b / 9.8
Hope this helps!! :)
