Answer:

-0.9231

Step-by-step explanation:

Given cos theta = 0.3846 within the range 3π/2<theta<2π

Costheta = 0.3846

Theta = arccos(0.3846)

Theta = 67.38°

Since 67.38° didn't fall within the range of theta, we will locate our theta using the quadrant.

Since cos is positive in the 4th quadrant,

Theta = 360-67.38°

Theta = 292.62°

Sin(theta) = sin(292.62°)

= -0.9231

DIA [1.3K]

Company A-> charges $75 and unlimited millage.

Company B-> initial fee $55 and charges +$0.8 for every mile driven.

The inequality that represents for what millage will company A charges less than company B is:

Let m be the number of miles

[tex]\begin{gathered} 75<55+0.8m \\ 75-55<0.8m \\ 20<0.8m \\ \frac{20}{0.8}For 25 miles company A will charge less than company B.

What is a common denominator for 1/7 and 1/3?<br><br> a 18<br> b 21<br> c 3<br> d 4
Nataliya [291]

Answer:

B. 21

Step-by-step explanation:

The fractions are there to just make the problem seem complicated, but just rewrite it without the fractions.

"What is a common multiple for 7 and 3?"

In this problem it's easy, all you have to do is guess and check.

A: A doesn't work. 7 is not a factor of 18.

B: B works! Both 3 and 7 are factors of 21.

C: C doesn't work. 7 is not a factor of 3.

D: D doesn't work. Neither are a factor of 4.

They only leave us with one solution, B.
