Answer:

C) Sin 2theta = root3/2, cos 2theta = 1/2

Step-by-step explanation:

If theta is between 0 degrees and 90 degrees, that means it's in the 1st quadrant.

If you look at a labeled unit circle, the only value where sin (y-value) of theta is at pi/6 radians. That means, theta equals pi/6. So 2theta is just pi/6 * 2 which is pi/3. Sin (pi/3) is equal to root3/2.

We know 2theta is pi/3, so the cos (x-value) of 2theta on a labeled unit circle is 1/2, which means cos 2theta is 1/2.

Answer:

\frac{\pi }{6}

Step-by-step explanation:

\frac{7\pi }{6} is an angle in the third quadrant

To find the reference angle subtract π from it

reference angle = \frac{7\pi }{6} - π = \frac{\pi }{6}

Points F and E on the coordinate grid below show the positions of two midfield players of a soccer team:
Lelechka [254]

Answer:

F is E reflected across the y-axis; only the signs of the x-coordinates of F and E are different.

Step-by-step explanation:

The question is incomplete. Here is the complete question.

" Points F and E on the coordinate grid below show the positions of two midfield players of a soccer team:

Coordinate grid shown from negative 4 to positive 4 on x-axis and negative 4 to positive 4 on y-axis. From the origin, point E is 1.5 units to the left and 3 units up. From the origin, point F is 1.5 units to the right and 3 units up.

Which statement best describes the relationship between the positions of the two midfield players? (1 point)

Based on the coordinate of E;

The value on the x axis is -1.5 since the point is 1.5unitsTO THE LEFT from the origin(-ve x-axis acts towards the left in space). The value on the y-axis will be +3units since its 3units UP(+ve y axis acts upward).

The E coordinates will therefore be (-1.5, 3)

Similarly, for coordinate F:

If from the origin, point F is 1.5 units TO THE RIGHT, then the x-axis will be +1.5 (x-axis is positive towards the right) and +3 units up(+ve y axis acts upward).

The F coordinate will therefore be;

(1.5, 3).

From both coordinates, it can be seen that both x axis are of the same value but different signs. This means that the points E and F will act in the opposite side of the y-axis and a reflector of each other.

Based on the explanation above, it can be concluded that "F is E reflected across the y-axis; only the signs of the x-coordinates of F and E are different."

A taxicab company charges $3.00 per ride and $0.75 for each mile driven. Your budget allows you to spend more than $10.00 but le
liraira [26]
The inequality is: x*0.75 + 3.00  < 20.00, where x represents the number of miles. When you solve the inequality, you get 22.66 miles. When you round up to 23 miles, you don't satisfy the inequality, so you have to round down to 22 miles.

Answer: (C) 22 miles
