Answer:

4u= - 4i - 24j

u +w = -9i - 3j

Step-by-step explanation:

The question is on operation of vectors

Given u= -i -6j  and w= -8i+3j

Then 4u = 4{ -i-6j}

4u= - 4i - 24j

u+w= -i -6j + -8i+3j......................collect like terms

= -i -8i + -6j +3j

= -9i + -3j

= -9i - 3j

two circles are externally tangent to each other. One circle has a diameter of 62 yards and the distance between the centers of
maksim [4K]

Answer:

108 yards

Step-by-step explanation:

Let circle A be the circle with the 62 yard diameter

Let circle B be the circle whose diameter we are trying to solve for.

  • Externally tangent circles are circles which touch each other and share a common external tangent.
  • Circle A has a tangent of 62 yards and thus a radius ( half the diameter) of 31 yards.
  • The distance between the centers of the 2 circles is 85 yards. If you subtract the radius ( distance from the center of the circle to its circumference) of circle A then we'll only be left with the radius of circle B.
  • 85 - 31= 54 yards which is the radius of circle B
  • To get the diameter: 54 x 2 = 108 yards
