Kendall has three jars of golf balls. One jar has a white and pink golf ball. The second jar has an orange and purple golf ball.
Mila [183]

Answer:

<h2>The total number of outcomes is 8.</h2>

Step-by-step explanation:

We know that there are different golf balls, white and pink, orange and purple, yellow and red. There are three jars with two golf balls each.

If Kendall chooses one golf ball from each jar, the total number of balls selected would be 4. Now, there are two different colors per jar, and 8 total golf balls with different colors. But, the sets can't have repetitions, and the order matters.

Having said that, the total number of possible sets is:

  • White, Orange, Yellow.
  • White, Purple, Red.
  • White, Orange Red.
  • White, Purple, Yellow.
  • Pink, Orange, Yellow.
  • Pink, Purple, Red.
  • Pink, Purple, Yellow.
  • Pink, Orange, Red.

Notice that these eight outcomes includes all possible results.

Therefore, there are 8 possible outcomes.

the volume V of a right circular cylinder of height 3 feet and radius r feet is V=V(r)=3(pi)(r^2). find the instantaneous rate o
Aleksandr-060686 [28]

When I see the words "instantaneous rate of change", I have to assume that you're in some stage of pre-calculus in your math class.

The instantaneous rate of change of a function is just its first derivative.

We have the function

                                   V(r) = 3 π r²

and we need its first derivative with respect to ' r '.  That shouldn't be
too hard, because the ' 3 π ' is nothing but constants.

Watch me while I do it slowly for you:

-- The derivative of  ' r² ' with respect to ' r ' is ' 2r '.

-- The derivative of V(r) with respect to ' r ' is  (3 π) times the derivative of  ' r² '.

-- The derivative of V(r) with respect to ' r ' is  (3 π) times (2r) =  <u>6 π r</u> .

The value of the derivative when r=3 is (6 π 3) = 18π = about <em>56.5 feet³/foot .</em>

Find the vertices of the image after the given transformation (x,y)—&gt; (2x, 1/3y)
Olin [163]

Answer:

see explanation

Step-by-step explanation:

the translation rule (x, y ) → (2x, \frac{1}{3} y )

means multiply the x- coordinate by 2 and multiply the y- coordinate by \frac{1}{3} ), so

A (- 1, - 3 ) → A' (- 2, - 1 )

B (4, - 3 ) → B' (8, - 1 )

C (4, 3 ) → C' (8, 1 )

D (- 1, 3 ) → D' (- 2, 1 )
