Write the equation of the circle that has a center of (-7, 17) with a radius of V19.

kipiarov [429]

I think your question seems to be :-

Write the equation of the circle that has a center of (-7, 17) with a radius of √19

So , as we know that the equation of circle with centre at (h,k) and radius r is given by ${\bf{(x-h)^{2}+(y-k)^{2}=r^{2}}}$ . Now , using same concept in this question ;

${:\implies \quad \sf \{x-(-7)\}^{2}+(y-17)^{2}=(\sqrt{19})^{2}}$

${:\implies \quad \bf \therefore \quad \underline{\underline{(x+7)^{2}+(y-17)^{2}=19}}}$

This is the required equation of Circle

Solve the equation 2 16x + 20 = 0 to the nearest tenth.

Alenkasestr [34]

Answer:

x ≈ - 1.3

Step-by-step explanation:

16x + 20 = 0

16x + 20 - 20 = 0 - 20

16x = - 20

16x ÷ 16 = - 20 ÷ 16

x = - 1.25

$x=-1\frac{1}{4}$

- 1.25 rounds to - 1.3

Jack and jill painted one-half of Their bedroom in three-fourths of an hour. At this rate, how long would it take them the pain

zzz [600]

Well they painted HALF the room in 3/4 of an hour.

That means that, considering they keep up the same speed, it will take them 3/4 of an hour to do the OTHER half.

This means that it will take them....

1 and 1/2 hours to do their entire room.
