Answer:
Domain will be all positive numbers.
Therefore Option D is correct.
Step-by-step explanation:
A tire is of circular shape so the circumference of a circle we know which is:
Where, C is circumference,, r is radius
So, Here the circumference of tire will also be:
Domain is the value that x will take
And here r is corresponding with r.
So, radius cannot be negative,
So, Domain will be all positive numbers.
Therefore Option D is correct.
Its a rational number because it can be expressed as a fraction
Answer
Find out the how many birds were at the shelter on Wednesday .
To prove
let us assume that the number of birds be = x
let us assume that the number of cats be = y
As given
An animal shelter spends $3.00 per day to care for each bird and $7.00 per day to care for each cat.
Alexandra noticed that the shelter spent $174.00 caring for birds and cats on Wednesday.
than the equation becomes
3x + 7y = 174
As given
Alexandra found a record showing that there were a total of 34 birds and cats on Wednesday.
than the equation becomes
x + y = 34
Than the two equation are
3x + 7y = 174
and x + y = 34
multiply 3 by x + y = 34 and subracted from 3x + 7y = 174
3x - 3x + 7y - 3y = 174 - 102
4y = 72
y = 18
put in the equation x + y = 34
18 + x = 34
x = 34 - 18
x = 16
The number of birds at the shelter on wednesday is 16 .
8 + 3 (4 - n )
n= 3
8 + 3( 4-3)
8 + 3 * 1
8 + 3 = 11
