The circle below is centered at the point (3,-4) and has a radius of length 3.
What is its equation?
O A. (x + 4)2 + (y - 3)2 =
32
O B. (x-3)2 + (y + 4)2 = 9
C. (x-4)2 + (y + 3)2 =
32
O
D. (x-3)2 + (y - 4)2 = 9

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
