Answer:

(x - 6)^2 + (y + 4)^2 = 4

Step-by-step explanation:

formula for a circle

( x - h )^2 + ( y - k )^2 = r^2

(h,k) is the center

r is the radius

(6,-4) is center

2 is radius

Substitute in numbers and watch the negatives.

grandymaker [24]

Answer:

the average velocity is 86 km/h for the trip

Step-by-step explanation:

from the definition of average velocity

average velocity = distance covered / time required = 1682 km /(19 h + 28 min/60 min/h) = 86 km/h

therefore the average velocity is 86 km/h for the trip

The diameter d in inches of a rope required to lift a weight of w tons is given by the function d = 10w/ π . How much weight can

Ilia_Sergeevich [38]

Answer:

Option D) 1.26 tons

Step-by-step explanation:

we have

$d=\frac{10w}{\pi}$

where

d is the diameter of a rope in inches

w is the weight in tons

we have

$d=2(2)=4\ in$ ----> the diameter is two times the radius

substitute the value of d and solve for w

$4=\frac{10w}{\pi}$

$w=\frac{4\pi}{10}=0.4\pi\ tons$

assume

$\pi =3.14$

$0.4(3.14)=1.26\ tons$
