a laboratory technician needs to make a 40-liter batch of a 40% acid solution. How can the laboratory technician combine a batch
Anettt [7]
The answers comes to be for every 1 unit of pure acid (100%) add three units of 20% and you get the desired 40% 


so if you need 40 L (i don't know what container sizes there are so i can't give you an exact amount just add 1 part 100% acid and 3 parts 20% acid) <span />

Which of the statements are true about the function f given by f(x) = 100-e? Select all that apply.
tatiyna

From the above function, it is clear that the value of f is never 0. Hence the statement that is true is (Option E), See explanation of same below.

<h3>What is the explanation for the above function?</h3>

Note that the function is related to Euler's number which is depicted as:
e ≈ 2.7182. The function is given as:

f(x) = 100 * e^{-x}

Assuming x = -2, we'd have:

100 * 2.7182^{-2}

= 271.82^{-2}

= 0.00001353354

Hence, even when x tends < 0 the function f(x) thus, is never 0. See the attached graph for confirmation.

Which of the following is not an asymptote of the hyperbola xy = -42? y = 0 x = 0 y = x
Rainbow [258]

Given:

The equation of the hyperbola is:

xy=-42

To find:

The the equation which is not an asymptote of the hyperbola.

Solution:

We have,

xy=-42

It can be written as:

y=\dfrac{-42}{x}

Equating denominator and 0, we get

x=0

So, the vertical asymptotic is x=0.

The degree of numerator is 0 and the degree of denominator is 1.

Since the degree of numerator is greater that the degree of denominator, therefore the horizontal asymptote is y=0 and there is no oblique asymptote.

Therefore, y=x is not an asymptote of the given hyperbola and the correct option is C.

Can I get some help here?
andrew-mc [135]

Answer:

AB, CB, AC

Step-by-step explanation:

All the angles in a triangle added up equal 180 degrees

Start by finding the measure of angle A

A + 86 + 27 = 180

A + 113= 180

A = 67 degrees

Now order them

86 is greater than 67 and 27 so B is the greatest

27 is less than 86 and 67 so C is the smallest

67 is less than 86 but greater than 27 so A is in the middle

Now for the sides..

AB is opposite angle C so it's the shortest

CB is opposite angle A so it's in the middle

AC is opposite angle B so it's the longest

I hope this helps!!!
