Answer:
0.2857 is not a rational number.
Step-by-step explanation:
Because rational numbers have to be greater than 1. Decimals are not over 1 so it is not a rational number. Your welcome!
Answer:
The set of all points on a plane equidistant to a given point.
Answer:
Step-by-step explanation:
Answer:
Ok, the domain is the set of values that we can input in a function.
In this case, we have:
y = Ix - 6I + 3.
Notice that there is no restriction here, x can actually take any value, then the domain will be the set of all real numbers.
The correct domain is x, x ∈ R
Now, if we had (for example) something like:
y = Ix - 6I < 3
Now we have a restriction in the domain because we can not have y equal or larger than 3.
To find the domain, we can break the absolute value:
Ix - 6I < 3
is equivalent to:
-3 < x - 6 < 3
now let's add 6 in each side.
-3 + 6 < x - 6 + 6 < 3 + 6
3 < x < 9
That will be the domain in that case.
Question: 50 is what percent of 32?
Answer:156.25 or 156.3
Step 1: We make the assumption that 32 is 100% since it is our output value.
Step 2: We next represent the value we seek with x
Step 3:100%=32
Step 4:x%=50
Step 5:100%=32 x%=50(2)
Step 6:100%/x%=32/50
Step 7:x%/100=50/32 will give u 156.25% or round to the nearest tenth 156.3%
