Answer:

x = 2+1/3i or 2-1/3i

Step-by-step explanation:

The equation of interest can be written in vertex form as ...

9(x -2)² +1 = 0

so its solutions can be found by subtracting 1, dividing by 9, taking the square root, then adding 2.

x = 2 ± √(-1/9)

In the desired form, the zeros of the given expression are ...

x = 2 +1/3i or 2 -1/3i

A student is trying to construct triangles using four different sets of angles. Th angles in each set are given below. Which set

sladkih [1.3K]

Well I can't be for sure but I know for a fact its not set IV it's not possible to make a triangle out of all right angles. Set II, well, that isn't right either. You can't make a triangle out of all obtuse angles. Like the right angle one, its not possible you can only use one obtuse or right angle in a triangle other wise it's not going to be a triangle. I'd say go try Set III since that would most likely make an equilateral triangle.

Misha Larkins [42]

Answer:

<em>The club needs to raise $477 to go on an the field trip.</em>

Step-by-step explanation:

Each student in the club has to raise $53 by selling chocolate bars.

There are 9 students in the club.

Now for finding the total money raised by all 9 students, we just need to multiply $53 by 9.

So, the total money raised $=\$53\times 9= \$477$

Thus, the club needs to raise $477 to go on an the field trip.
