Circle X has radius r X = 6 units and circumference C X = 12 π units. Circle Y has circumference C Y = 6 units. Which equation i

slega [8]

Answer:

$ry=\frac{rx}{2\pi }$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

Circle X

$rx=6\ units$

$Cx=12\pi\ units$

Circle Y

$Cy=6\ units$

Find the radius ry

we know that

$Cy=2\pi ry$

substitute the value of Cy

$6=2\pi ry$

$ry=\frac{6}{2\pi }$

Remember that the value of rx is $rx=6\ units$

substitute

$ry=\frac{rx}{2\pi }$

I need help with number 2

alex41 [277]

First you have to figure out what IS 1/4 of 52, so all you need to do is put in your calculator 52 X .25 and get your answer

Then type in all of the four questions underneath into your calculator and chose the one that does NOT result in your original answer

garri49 [273]

ivied the total number of tennis balls buy the number of cans to see how many tennis balls are in 1 can

9 divided by 3 = 3

there are 3 tennis balls per can

fraction would be 3/1 ( meaning 3 balls to 1 can)

HELP with these questions

zlopas [31]

Step-by-step explanation:

transform the parent graph of f(x) = ln x into f(x) = - ln (x - 4) by shifting the parent graph 4 units to the right and reflecting over the x-axis

(???, 0): 0 = - ln (x - 4)

$\frac{0}{-1} = \frac{-ln (x - 4)}{-1}$

0 = ln (x - 4)

$e^{0} = e^{ln (x - 4)}$

1 = x - 4

+4 +4

5 = x

(5, 0)

(???, 1): 1 = - ln (x - 4)

$\frac{0}{-1} = \frac{-ln (x - 4)}{-1}$

1 = ln (x - 4)

$e^{1} = e^{ln (x - 4)}$

e = x - 4

+4 +4

e + 4 = x

6.72 = x

(6.72, 1)

Domain: x - 4 > 0

+4 +4

x > 4

(4, ∞)

Vertical asymptotes: there are no vertical asymptotes for the parent function and the transformation did not alter that

No vertical asymptotes

*************************************************************************

transform the parent graph of f(x) = 3ˣ into f(x) = - 3ˣ⁺⁵ by shifting the parent graph 5 units to the left and reflecting over the x-axis

Domain: there is no restriction on x so domain is all real number

(-∞, ∞)

Range: there is a horizontal asymptote for the parent graph of y = 0 with range of y > 0. the transformation is a reflection over the x-axis so the horizontal asymptote is the same (y = 0) but the range changed to y < 0.

(-∞, 0)

Y-intercept is when x = 0:

f(x) = - 3ˣ⁺⁵

= - 3⁰⁺⁵

= - 3⁵

= -243

Horizontal Asymptote: y = 0 (explanation above)
