Answer:
Step-by-step explanation:
The cube has 6 equal faces.
<u>Total surface area:</u>
- S = 6a²
- S = 6*(0.7 m)² = 6*(70 cm) ² = 29400 cm²
irrational number, any real number that cannot be expressed as the quotient of two integers.
Any number that can be written as a fraction with integers is called a rational number . For example, 17 and −34 are rational numbers. (Note that there is more than one way to write the same rational number as a ratio of integers.
1st Is rational
2nd one is irrational
3rd is irrational
4th is rational
Answer:
10
Step-by-step explanation:
The average r. of c. of a function f(x) on an interval [a,b] is:
f(b) - f(a)
--------------
b-a
You'll need to apply this to all four of the given functions.
First function: f(x) = x^2 + 3x
a= -2; b= 3
Then the ave. r. of c. for this function on this interval is:
18 - (-2) 20
------------------ = ---------- = 4. y increases by 4 for every unit increase in x.
3-(-2) 5
Do the same thing for the other 3 functions.
Then arrange your four results in descending order (greatest to least).
The range will be all ur y values...just as the domain is all the x values
so ur range is {5,6 }...notice that even though they repeat, u only have to list them once
