A cube has side lengths of 2/5 of an inch, what is the surface area and volume of the cube?

Mathematics
1 answer:
saul85 [17]3 years ago
4 0

Answer:

Surface area - 0.96, Volume - 0.064

Step-by-step explanation:

2/5- 0.40

For surface area, the equation is 6a^2

When you fill in the variable its

6(0.4)^2

follow pemdas, so you do the exponents first

(0.4)(0.4)

0.16

6(0.16)

0.96

The formula for volume is a^3

0.4^3

(0.4)(0.4)(0.4)

(0.16)(0.4)

0.064

State whether f is a function
Alenkinab [10]
<h2>Answer:</h2>

y=\pm (\frac{x}{6})^{\frac{1}{4}} \ is \ not \ a \ function

<h2>Step by step solution:</h2>

A function f from a set A to a set B is a relation that assigns to each element x in the set A exactly one element y in the set B. The set A is the domain (also called the set of inputs) of the function and the set B contains the range (also called the set of outputs). On the other hand, a function has an inverse function if and only if passes the Horizontal Line Test for Inverse Functions. This test tells us that a function f has an inverse function if and only if there is no any horizontal line that intersects the graph of f at more than one point. So the function is called one-to-one. The graph of f is shown below. As you can see, this function does not pass the Horizontal Line Test, therefore the inverse is not a function. However, let's find f^-{1}(x):

f(x)=6x^4 \\ \\ Substitute \ f(x) \ by \ y \\ \\ y=6x^4 \\ \\ Interchange \ x \ and \ y: \\ \\ x=6y^4 \\ \\ Solve \ for \ y: \\ \\ y^4=\frac{x}{6} \\ \\ Solving \\ \\y=\pm \sqrt[4]{\frac{x}{6}} \\ \\ \boxed{y=\pm \left(\frac{x}{6}\right)^{\frac{1}{4}}}

and this is not a function because there are elements in the set of inputs that match with two elements in the set of outputs.

Answer:

4. slices

Step-by-step explanation:

because If you turn 3/5 in to a decimal you get 0.6 and each slice of cheese weighs 0.15 so you do 0.6 divided by 0.15

What are the important things to remember or be careful about when adding and subtracting polynomials?
prisoha [69]
Be careful you don't add unlike terms together (e.g. x^2 and x cannot be added or subtracted together). 
<span>Be careful you don't mistake the 2 in x^2 as another number. Same for x^3, x^4. etc.</span>
