Answer:

A. The degree of the polynomial is even.

Step-by-step explanation:

The end behavior is the same in both directions (for -x and for +x, y → ∞), so the degree of the polynomial is even.

The constant term is the y-intercept. It is not an integer, so cannot be said to be even or odd.

Algebra need to solve question

Zigmanuir [339]

Answer:

Step-by-step explanation:

$(3+\sqrt{7})(3-\sqrt{7}) \\$

First do 3 x 3 = 9 - keep this 9 to the side for now

Then do 3 x $-\sqrt{7}$ = $-\sqrt{21}$ - also keep this to the side for now

Then do $\sqrt{7}$ x 3 = $\sqrt{21}$

Then do $-\sqrt{7}$ x $\sqrt{7}$ = -7

So,

9 $-\sqrt{21}$ + $\sqrt{21}$ - 7

Therefore, 9-7 = 2

a jewelry store buys 24 necklaces for $300. the store wants to make a profit of $540. assuming it sells all 24 necklaces, how mu

Serga [27]

If its meaning making a profit after the $300 then:
540+300=840
840/24= 33.60
They would charge $33.60 per necklace.

If you were meaning a profit of $540 total then:
540/24=22.5
They would charge $22.50 per necklace.

Which of the following best explains why

Dima020 [189]

We can see values of angles in degrees first

$\frac{5\pi}{6} = \frac{5 \times 180}{6}= \frac{900}{6}$ = 150°

Similarly

$\frac{5\pi}{3} = \frac{5 \times 180}{3}= \frac{900}{3}$ = 300°

Now reference angle means positive acute angle they will have

As we can see in attachment 150° lies in second quadrant so its reference angle will be 180°-150° = 30° from x axis line as shown.

Where as angle 300° lies in fourth quadrant so its reference angle will be 360° - 300° = 60° from x axis as shown. So clearly both reference angles are different . So 1st choice " angles donot have same reference angle" best explains it

Choice (2) and (3) are incorrect as tan is positive only in first and third quadrants and angle 300° is in fourth quadrant.

since angle 150° is in second quadrant and 300° is in fourth quadrant so both will have same negative sign so choice (4) is not correct.

So final ansewr is choice (1) "the angles donot have same reference angle"
