Answer: F

Step-by-step explanation:

We know the angle is in the first quadrant, so its argument is in between 0 and 90 degrees.

This eliminates D and E.

Also, its modulus is the distance from the origin, which in this case is $\sqrt{3^2 + 1^2}=\sqrt{10} \approx 3.16$

The answer that best matches this is F

Answer:

The number of tickets sold to the public was 375

Step-by-step explanation:

<u><em>The complete question is</em></u>

At a charity basketball game, 450 tickets were sold to students at a school. The remaining x tickets were sold to the public. The students paid $15 and public $25. When all the tickets were sold, $10,500 was collected. How many tickets were sold to the public?

Let

x ----> number of tickets sold to the students

y ----> number of tickets sold to the public

we know that

$x+y=450$ ----> equation A

$15x+25y=10,500$ ----> equation B

Solve the system by graphing

The solution is the intersection point both graphs

using a graphing tool

The solution is the point (75,375)

see the attached figure

therefore

The number of tickets sold to the public was 375

The function f(x) is defined as follows:

Leno4ka [110]

Answer:

$f(-3)=-8\\f(2)=4$

Step-by-step explanation:

In order to find the values of a piecewise function, we first have to determine which piece we are using.

For $f(-3)$ , x=-3. This means that we need to use $3x+1$ as $-3\leq 0$

$f(-3)=3(-3)+1\\\\f(-3)=-9+1\\\\f(-3)=-8$

For $f(2)$ , x=2. This means that we need to use $f(x)=4$ as x is equal to 2.

$f(x)=4$
