Answer:

(x - 5)² + (y + 3)² = 16

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (5, - 3) and r = 4, so

(x - 5)² + (y - (- 3))² = 4², that is

(x - 5)² + (y + 3)² = 16

It takes Bruce 12 h to complete his training. It takes Oliver approximately 2 days, 2 h, and 15 min to complete his training. Ho

Bond [772]

Answer:

Oliver completed his training work in 50.25 hours

Step-by-step explanation:

we know that

$1\ day= 24\ hours$

$1\ hour=60\ minutes$

we have

$2\ days, 2\ h,\ and\ 15\ min$

Convert days to hours

$2\ days=2(24)=48\ hours$

Convert minutes to hour

$15\ min=15(1/60)=1/4=0.25\ h$

$2\ days, 2\ h,\ and\ 15\ min=(48)+(2)+(0.25)=50.25\ h$

therefore

Oliver completed his training work in 50.25 hours
