I hope it’s helps i have to write more so I’m writing
Answer:
{2,3}
Step-by-step explanation:
The domain is the set of all the values of x. The range is the set of all the values of y.
Answer:
D, B, F
Step-by-step explanation:
$2 each pound
x= pounds
y= total cost
1 pound= $2
the $2 : constant
the number of pounds: variable
the equation is y=2x
1 pound: $2
2 pounds: $4
4 pounds: $8
5 pounds: $10
these also could be written as coordinates
the coordinates are (1,2),(2,4),(4,8),(5,10)
Answer:
A. 9.6
B. √92
Step-by-step explanation:
<h3>A.</h3>
Rational: 9.6. It is rational because it is a terminating decimal number.
__
<h3>B.</h3>
Irrational: √92 ≈ 9.59166.... It is irrational because it is the square root of an integer that is not a perfect square. All such square roots are irrational.
_____
<em>Additional comment</em>
In general, the n-th root of an integer that is not a perfect n-th power will be irrational. For example, ∛885 ≈ 9.600954766... is irrational, because 885 is not a perfect cube. (9³=729, 10³=1000)
Trig functions of (non-zero) rational angles in radians will be irrational. For example, tan(1.467) ≈ 9.5996286... is irrational.
