What scale factor (common ratio) can be applied to Cone 1 to make Cone 2?(3/9) (2/6)

answer:

-4 1/2.

step-by-step explanation:

9/10 / -3/15

inverting the divisor and multiplying:

= 9/10 * 15 / -3

= 9/10 *   -5

= -45 / 10

= -4 1/2

answer:

a. 3 inches

step-by-step explanation:

the radius bc and the tangent ab form a right angle, so triangle abc is a right triangle. bc and cd are radii of the same circle, so they are congruent.

a^2 + b^2 = c^2

(bc)^2 + (ab)^2 = (cd + ad)^2

let the radius bc = cd = x.

x^2 + 4^2 = (x + 2)^2

x^2 + 16 = x^2 + 4x + 4

16 = 4x + 4

12 = 4x

x = 3

answer: 3 inches

answer:

| v | = 5,831

step-by-step explanation:

take the starting point.

in the graph you can see that the coordinates are (1,1)

then it takes the final point that has the coordinates (4.6)

now subtract the final coordinates - the initial coordinates

v = < >

v = < 4-1, 6-1>

v = < 3, 5>

then, by definition, the magnitude of the vector is:
