Answer:
is the inequality to find the Domain of f(x)
Step-by-step explanation:
When we have a function where the variable "x" is inside a square root, we find its Domain by looking for all those values x for which the function is defined for the root, which means all the x-values that make the expression inside the root larger than or equal to zero, avoiding the values smaller for which the square root is not defined.
Therefore, in this case , for
we ask for the x-values that verify:
where we have isolated x on one side of the equal sign.
This would be the definition of the Domain of the function.
Answer:
The number of pages had Clint read prior to study hall were <u>127 pages</u>.
Step-by-step explanation:
Given:
Clint after 20 minutes is on page 151.
And, after 45 minutes he is on page 181.
Now, to find the pages Clint read prior to study hall.
<em>The time difference = 45 minutes - 20 minutes.</em>
<em> = 25 minutes.</em>
<em>Difference between the pages = 181 - 151</em>
<em> = 30 pages.</em>
If Clint is reading each page at same speed.
Then, in 25 minutes he can read = 30 pages.
So, in 1 minute he can read = 30 ÷ 25 = 1.2 pages.
Thus, in 20 minutes he can read
Now, number of pages Clint had read prior to study hall = 151 - 24
= 127 pages.
Therefore, the number of pages had Clint read prior to study hall were <u>127 pages</u>.
