Step-by-step explanation:
√z is defined only when z >= 0
Therefore √x - 1 is defined only when (x - 1) >= 0, x >= 1.
The only graph that shows the domain x >= 1 is graph Y.

There is a cool trick you can do. Lets take 28 and square it.
First you round the number up. 28 rounded is 30. You rounded up by 2 (30-28=2) so you minus 2 from 28.
You are left with these two numbers, 26 and 30. Add a zero to the 26.
You now have 260 and 3 (you remove 0 on the 30 since you added it to the 26)
Then you multiply by 3.
260x3=780
Then you add the square of the number you rounded up too, which is 2.
You are left with this equation.
(2^2)+780= 784
28x28=784.
This works for numbers below 100 and integers

Need help plz don’t know what is the answer.
Answer:
A
Step-by-step explanation:
If you subtract 4 and add 16 you get 37
The square root of 36 is 6 and the square root of 49 is 7
so since 37 is closer to 36 it has to be than 7 and a little more than 6

Lamar is considering two loans.
Loan A
Loan B
Principal
$4,500
$4,300
Interest rate
5%
6%
Time in years
3
3
Which loan will have the lowest total payback?
Step-by-step explanation:
know:
Loan A
Principal
$4500
Interest rate
5%
Time in years
3
If 100% => $4500
5% =>X
X = 5% × $4500 ÷ 100% = $225
Loan A = $4500 + $225 = $4725
Loan B
Principal
$4300
Interest
6%
Time in years
3
If 100% => $4300
6% =>X
X = 6% × $4300 ÷ 100% = $258
Loan B = $4300 + $258 = $4558
Loan B has the lowest total payback.
The Loan B has the lowest total payback than the Loan A.
How to calculate the Payback?WE can calculate the payback in both loan as;
Loan A;
Principal = $4500
Interest rate = 5%
Time in years = 3
If 100% => $4500
X = 5% × $4500 ÷ 100%
X = $225
Loan A = $4500 + $225 = $4725
Loan B;
Principal = $4300
Interest = 6%
Time in years = 3
If 100% => $4300
X = 6% × $4300 ÷ 100%
X= $258
Loan B = $4300 + $258 = $4558
Hence, the Loan B has the lowest total payback than the Loan A.
