For your trouble answering this, you will get 30 points. for all the trouble this may cause.
Gennadij [26K]

Answer:

read below

Step-by-step explanation:

A1: I think D because you have a medium average mix of concentrate that will mix with only 2 more cups than itself, so this would keep it fine. A could also work sooooo.... A or D. i dont know at this point. B COULD be a possible solution but it's 5 vs 9.

A2: C

1 cup of concentrate vs 2 water.... the water will make it MUCH more of a clear color.

Question C: this is more time consuming and I am tired so for you this might be easier if you're not as tired so based on what I'm reading you need to do math for each of the 4 options above, concentrate and water mix, and then divide the total of the 2 types of cups for every option.

Hope Q1 and Q2 helped though!

If f(x)= 3x^2 + 3x^1/2 +3x what is the value of f(-9)
Dahasolnce [82]

Answer:

216 + 9i

Step-by-step explanation:

Given: f(x) = 3x² + 3x^{1/2} + 3x

When x = -9, f(x) equals to;

3(-9)²  + 3(-9)^{1/2} + 3(-9)

243 + 3(3i) - 27

243 + 9i - 27

216 + 9i

What is the midpoint of (2, -3) and (4, 1)
daser333 [38]

Answer:

The answer is

<h2>( 3 , - 1)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )\\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(2, -3) and (4, 1)

The midpoint is

M = ( \frac{2 + 4}{2}   \: , \:  \frac{ - 3 + 1}{2} ) \\  = ( \frac{6}{2}  \: , \:  -  \frac{2}{2} )

We have the final answer as

<h3>( 3 , - 1)</h3>

Hope this helps you
