Answer:
4.2 days
Step-by-step explanation:
Number of Weeks during which she practiced =4 weeks
Convert from weeks to days = 4 X 7=28 days
Since she practices all of her scales 15% of her practice days.
Number of Days that she practiced all her scales
=15% X 28
=0.15 X 28
=4.2 days
Answer:
The restrictions will be:
x ≠ 0;
x² ≠ 0 ⇒ x ≠ 0 ;
5x² ≠ 0 ⇒ x² ≠ 0 ⇒ x ≠ 0;
Step-by-step explanation:
As we know that
There are two genuine reasons why domains are restricted.
We cannot divide the expression by 0 as it would be undefined then.
We cannot take the square root of a negative number, as the result will not be a defined.
Considering the expression
As we can not put x = 0 in the denominator as it would make the expression undefined.
In other words, the certain values which make the denominator equal to zero for a rational expression will be restricted values.
Hence, the restrictions will be:
x ≠ 0;
x² ≠ 0 ⇒ x ≠ 0 ;
5x² ≠ 0 ⇒ x² ≠ 0 ⇒ x ≠ 0;
Answer:
5
Step-by-step explanation:
Each triangle is a myriad of both |, ||, and |||.
Because BE = || and FE = ||| then BF = |
CD = 10 but thats equal to 2 | meaning that 1 | is 5.
