If the domain of the square root function f(x) is x<=7, which statement must be true?7 is subtracted from the x-term inside the radical.
The radical is multiplied by a negative number.
7 is added to the radical term.
The x-term inside the radical has a negative coefficient.

Answers

Consider the funcion $y=√(x)$ . The dmain of this function is $\ge 0$ and the range is $y\ge 0$ .

Now if $x\le 7$ you can calculate that

$x-7\le 0,\n 7-x\ge 0$

and the function $y=√(7-x)$ will have the domain $x\le 7$ (state this using that expression under the root is $\ge 0$ ).

As you can see the x-term inside the radical has a negative coefficient.

Answer: correct choice is D.

Correct answer is D.

The expression inside the radical must be greater than or equal to zero.

$x \leq 7\n0 \leq 7-x\n7-x \geq 0$

Therefore, the x-term inside the radical has a negative coefficient.

Tourist: "How many birds and lions do you have in your zoo?" Zookeeper:"There are 30 heads and 100 feet." Find the number of each animal. I need to know how to set this problem up in a system of linear equations. Thank you.

Answers

Each lion has 1 head. The number of lion heads is L .
Each bird has 1 head. The number of bird heads is B.
The total number of heads of all species is (L + B) = 30

Each lion has 4 feet. The number of lion feet is 4L .
Each bird has 2 feet. The number of bird feet is 2B .
The total number of feet of all species is (4L + 2B) = 100

The system of linear equations is:

L + B = 30
4L + 2B = 100 .

How many radians are in 300 degrees?

Answers

There are 5π/3 radians in 300 degrees.

To convert degrees to radians, we can use the formula:

Radians = Degrees x (π / 180)

Given that we want to convert 300 degrees to radians, we can plug this value into the formula:

Radians = 300 x (π / 180)

Simplifying this expression, we get:

Radians = 5π/3

Therefore, there are 5π/3 radians in 300 degrees.
