Solve the equation on the interval [0, 2pi): 12cos^2 x-9=0 What to do?

siniylev [52]

Answer:

$\large\boxed{x=\dfrac{\pi}{6}\ \vee\ x=\dfrac{5\pi}{6}\ \vee\ x=\dfrac{7\pi}{6}\ \vee\ x=\dfrac{11\pi}{6}}$

Step-by-step explanation:

$12\cos^2x-9=0\qquad\text{add 9 to both sides}\\\\12\cos^2x=9\qquad\text{divide both sides by 12}\\\\\cos^2x=\dfrac{9}{12}\\\\\cos^2x=\dfrac{9:3}{12:3}\\\\\cos^2x=\dfrac{3}{4}\to\cos x=\pm\sqrt{\dfrac{3}{4}}\\\\\cos x=\pm\dfrac{\sqrt3}{2}\\\\\text{Look at the picture}\\\\x=\dfrac{\pi}{6}\ \vee\ x=\dfrac{5\pi}{6}\ \vee\ x=\dfrac{7\pi}{6}\ \vee\ x=\dfrac{11\pi}{6}$

Question 2 of 15. Step 1 of 1

Answer:

A = -68.75p +2906.25

Step-by-step explanation:

We can solve for m and b using the given values of A and p.

1600 = m·19 +b

2150 = m·11 +b

Subtracting the second equation from the first, we have ...

-550 = 8m

m = -550/8 = -68.75

Substituting this into the first equation gives ...

1600 = 19·(-68.75) +b

b = 1600 +1306.25 = 2906.25

The desired linear equation is ...

A = -68.75p +2906.25

Alisa had some juice in a bottle. Then she drank 3/8 liter of juice. If this was 3/4 of the juice that was originally in the bot

Inessa [10]

3/4 x ? = 3/8

3/8 ÷ 3/4 = ?

3/8 x 4/3 = 12/24

12/24 = 1/2

1/2 of a liter was there to start.
